believe we are also the leader in developing and commercializing high intensity directed
acoustical devices, branded as our Long Range Acoustic Device or LRAD&#153;. We have filed
over 70 patent applications in the United States, and over 90 patent applications
internationally covering our various sound technologies and products. </FONT></P>

acoustic challenges. We offer our products for sale worldwide, but expect the largest

Our HyperSonic sound, or HSS, technology is a new parametric speaker technology that
creates sound &#147;in the air.&#148; Sound is generated along an air column using
ultrasonic frequencies, which are those above the normal range of hearing. The HSS sound
beam is highly directional and maintains sound volume over longer distances than
traditional loudspeakers. We believe our substantial intellectual property portfolio and
pioneering HSS products support our leadership position in the field of parametric
non-linear acoustics for sound reproduction. In October 2004, we released our HSS
Generation III (T120 and T220) product family, which has higher reliability, lower
distortion and higher output levels than previous models of our HSS products. </FONT></TD>

Our Long Range Acoustic Device, or LRAD technology produces variable intensity acoustical
sound intended for use in long-range delivery of directional sound information, which is
effectively a supercharged megaphone. LRAD products are designed and used as directed
long-range hailing and warning systems by both government and commercial customers. We
believe our LRAD product innovation, our growing engineering capabilities, and our
manufacturing and marketing competencies have established us as the leader in this new
marketplace. We are marketing LRAD throughout the U.S. Department of Defense as &#147;The
Sound of Force Protection&#153;&#148;, and our markets are expanding to include law
enforcement and commercial customers with significant security concerns. In fiscal 2004,
we developed a remote controlled pan/tilt version of LRAD for critical infrastructure
force protection applications, and we demonstrated our competency to engineer additional
new sound solutions for the U.S. Department of Defense. </FONT></TD>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
December 14, 2004, we entered into a Common Stock Purchase Agreement with Kingsbridge
Capital Limited which established a Committed Equity Financing Facility. Under the
Committed Equity Financing Facility we may, at our sole discretion, sell to Kingsbridge
and Kingsbridge has committed to purchase subject to certain significant limitations and
conditions precedent, up to $25,000,000 of our common stock. As part of this arrangement,
we issued a warrant to Kingsbridge to purchase 275,000 shares of our common stock at a
price of $8.60 per share. The warrant is exercisable beginning June&nbsp;14, 2005 and
until June&nbsp;14, 2010. </FONT></P>

Facility or upon exercise of the warrant. The number of shares ultimately offered for sale
by Kingsbridge is dependent upon the number of shares (i)&nbsp;we may decide to sell to
Kingsbridge under the Committed Equity Financing Facility at our sole discretion, subject
to certain significant limitations and conditions precedent, and (ii)&nbsp;we may be
required to sell to Kingsbridge upon exercise of the warrant. Kingsbridge does not have

Kingsbridge. However, we may receive up to $25 million in gross proceeds from the sale of
our stock to Kingsbridge under the Committed Equity Financing Facility, and up to
approximately $2.4 million upon exercise of the warrant. We are obligated to use 40% of
any funds we receive from sales of shares under the Committed Equity Financing Facility,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
have entered into a Committed Equity Financing Facility with Kingsbridge Capital Limited.
Under the terms of our agreement with Kingsbridge, we may, at our sole discretion, sell to
Kingsbridge, and Kingsbridge would be obligated to purchase, shares of our common stock
for up to $25 million in proceeds to us. The price at which we may sell shares of common
stock under the agreement is based on a discount to the volume weighted average market
price of the common stock for fifteen trading days following each of our elections to sell
shares. For each election to sell shares, we select the lowest threshold price at which
our stock may be sold, but the threshold price cannot be lower than $3.00 per share. In
the event the market price of our common stock falls below $3.41 per share, which after
giving affect to the discount would result in a price per share lower that the $3.00
minimum threshold price, the Committed Equity Financing Facility will not be an available
source of financing. In addition, we are obligated to use 40% of the proceeds we may raise
from the Committed Equity Financing Facility to prepay any outstanding interest and
principal on promissory notes we sold in December 2004 with an aggregate principal amount
of $2 million. Our agreement with Kingsbridge permits Kingsbridge to terminate the
Committed Equity Financing Facility if Kingsbridge determines that a material and adverse
event has occurred affecting the business, operations, properties or financial condition
of our company, or if any situation occurs that would interfere with our ability to
perform any of our obligations under the agreement. </FONT></P>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
issuance of shares under the Committed Equity Financing Facility will have a dilutive
impact on other stockholders and the issuance or even potential issuance of such shares
could have a negative effect on the market price of our common stock. In addition, if we
draw down the Committed Equity Financing Facility, we will issue shares to Kingsbridge at
a discount ranging from 8% to 12% of the daily volume weighted average prices of our
common stock during the fifteen day trading period after initiation of each draw down.
Issuing shares at such a discount will further dilute the interests of other stockholders. </FONT></P>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;To
the extent that Kingsbridge sells shares of our common stock issued under the Committed
Equity Financing Facility under this prospectus, our stock price may decrease due to the
additional selling pressure in the market. The perceived risk of dilution from sales of
stock to or by Kingsbridge may cause holders of our common stock to sell their shares, or
it may encourage short sales. This could contribute to a decline in our stock price. </FONT></P>

the date the registration statement becomes unavailable, multiplied by any positive
difference in price between the volume weighted average price on the trading day prior to
such period of unavailability and the volume weighted average price on the first trading

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
are permitted to suspend the availability of the registration statement if there is
material undisclosed information then existing or if we intend to file another
registration statement. However, if we suspend the registration statement for more than 30
days during any calendar year or more than six times in any twelve month period, we are
obligated to pay Kingsbridge liquidated damages. These liquidated damages provisions
generally provide that if the registration statement is suspended within fifteen trading
days following any settlement date for the purchase of our stock under the Committed
Equity Financing, we shall pay Kingsbridge a percentage of the decline in value, if any,
of shares held by Kingsbridge during the time the availability of the registration
statement is suspended as follows: 75% if such notice of suspension is delivered prior to
the fifth trading day after a settlement date, 50% if such notice of suspension is
delivered on or after the fifth and prior to the tenth trading day after a settlement
date, and 25% if such notice of suspension is delivered on or after the tenth and prior to
the fifteenth trading day after a settlement date. The amount of such liquidated damages
for any one period of suspension may not exceed $1.75 million. We may, in lieu of paying
such liquidated damages, offer to repurchase the securities held by Kingsbridge for a
price equal to the volume weighted average price on the trading day prior to such period
of ineffectiveness. We may also elect to pay such liquidated damages in shares of common
stock valued at the market value on the first trading day after such permitted suspension
ends. The liquidated damages could severely affect our liquidity, or to the extent we are

without the prior written consent of Kingsbridge, we are prohibited from issuing
securities that are, or may become, convertible or exchangeable into shares of common
stock where the purchase, conversion or exchange price for such common stock is determined
using a floating or otherwise adjustable discount to the market price of the common stock
(including pursuant to an equity line or other financing that is substantially similar to
an equity line with an investor other than Kingsbridge). In the past, we met our capital
needs through the sale of preferred stock and convertible notes which had floating price
features. We may have difficulty raising capital if Kingsbridge does not consent to our
use of such securities in the future. If we are unable to raise capital from Kingsbridge
or from sources that do not demand a floating price feature, we may have to severely
curtail our operations, which could cause a significant decrease in the price of our
common stock. </FONT></P>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Although
our LRAD products are designed to be used by both government and commercial customers, our
LRAD products have to date been predominately sold for government use. Within the
Government Group, our largest customer is a reseller of our products to end users in
various branches of the military such as the U.S. Navy, U.S. Marine Corps, U.S. Army and
the Department of Homeland Security. We have only recently achieved significant sales of
LRAD products, and the product has not yet been widely accepted in the government market.
Furthermore, the force protection and emergency response market is itself an emerging
market which is changing rapidly. If our LRAD product is not widely accepted by the
government, military and the developing force protection and emergency response markets,
we may not be able to identify other markets, and we may fail to achieve our sales

HSS, NeoPlanar and LRAD technologies have only recently been introduced to market and are
still being improved. Commercially viable sound technology systems may not be successfully
and timely produced by us due to the inherent risks of technology development, new product
introduction, limitations on financing, manufacturing problems, competition, obsolescence,
loss of key technical personnel and other factors. Revenues from our sound products have
been limited to date and we cannot guarantee significant revenues in the future. The
development and introduction of our products took longer than anticipated by management
and the introduction of new products could also be subject to delays. Customers may not
wait for newer versions of existing products or new products and may elect to purchase
products from competitors. We experienced quality control problems with some of our
initial commercial HSS units, and we may not be able to resolve future similar problems in
a timely and cost effective manner. Products employing our sound technology may not
achieve market acceptance. Our various sound projects are high risk in nature, and
unanticipated technical obstacles can arise at any time and result in lengthy and costly
delays or result in a determination that further exploitation is unfeasible. If we do not
successfully exploit our technology, our financial condition and results of operations and
business prospects would be adversely affected. </FONT></P>

fiscal 2003, due to performance failures of components in some of our first generation of
HSS systems, we agreed to voluntarily replace emitters on an estimated 700 HSS Generation
I units. At September 30, 2004, we had a warranty reserve of $331,917, of which $186,454
was reserved for this replacement program. During fiscal 2004, we incurred warranty
expense of $145,463 and we reduced our warranty reserve by $43,792 for products that were
no longer under warranty. We also applied $89,254 of incurred costs against the special

success, in part, depends on our ability to obtain and enforce intellectual property
protection for our technology, particularly our patents.&nbsp;&nbsp;There is no guarantee
any patent will issue on any patent application that we have filed or may file. Claims
allowed from existing or pending patents may not be of sufficient scope or strength to
protect the economic value of our technologies. Further, any patent that we may obtain
will expire, and it is possible that it may be challenged, invalidated or circumvented. If
we do not secure and maintain patent protection for our technology and products, our
competitive position will be significantly harmed because it will be much easier for
competitors to sell products similar to ours. Alternatively, a competitor may
independently develop or patent technologies that are substantially equivalent to or
superior to our technology.&nbsp;&nbsp;For example, patent protection on our LRAD product
is limited, and we may not be able to prevent others from introducing products with
similar functionality.&nbsp;&nbsp;If this happens, any patent that we may obtain may not

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
we expand our product line or develop new uses for our products, these products or uses

intellectual property rights. In addition, if we develop new products or enhancements to
existing products we cannot assure you that we will be able to obtain patents to protect
them. Even if we do receive patents for our existing or new products, these patents may
not provide meaningful protection. In some countries outside of the United States where
our products can be sold or licensed, patent protection is not available. Moreover, some
countries that do allow registration of patents do not provide meaningful redress for
violations of patents. As a result, protecting intellectual property in these countries is
difficult and our competitors may successfully sell products in those countries that have
functions and features that infringe on our intellectual property. </FONT></P>

companies in general and our company in particular have a history of depending upon and
using broad based employee stock option programs to hire, incentivize and retain employees
in a competitive marketplace. Currently, we do not recognize compensation expense for
stock options issued to employees or directors, except in limited cases involving
modifications of stock options, and we instead disclose in the notes to our financial
statements information about what such charges would be if they were expensed. An
accounting standard setting body has recently adopted a new accounting standard that will
require us to record equity-based compensation expense for stock options and employee
stock purchase plan rights granted to employees based on the fair value of the equity
instrument at the time of grant. We will be required to record these expenses beginning
with our fourth quarter of fiscal 2005. The change in accounting rules will lead to
increased reported net loss or, should we become profitable, a decrease in reported
earnings. This may negatively impact our future stock price. In addition, this change in
accounting rules could impact our ability to utilize broad based employee stock plans to
reward employees and could result in a competitive disadvantage to us in the employee
marketplace. </FONT></P>

the date the registration statement becomes unavailable, multiplied by any positive

or if we intend to file another registration statement with the SEC. However, we are
permitted to suspend the use of the registration statement for only up to 30 days during
any calendar year, and no more than six times in any 12 month period. In the event that we
exercise this right of suspension within fifteen trading days following any settlement
date for the purchase of our stock under the Committed Equity Financing Facility, we must
pay to Kingsbridge as liquidated damages a percentage of the decline in value, if any, of
shares purchased during the most recent draw down period and held by Kingsbridge, as
follows: 75% if such notice of suspension is delivered prior to the fifth trading day
after a settlement date, 50% if such notice of suspension is delivered on or after the
fifth and prior to the tenth trading day after a settlement date, and 25% if such notice
of suspension is delivered on or after the tenth and prior to the fifteenth trading day
after a settlement date. The amount of such liquidated damages for any one period of
suspension may not exceed $1.75 million. We may, in lieu of paying such liquidated
damages, offer to repurchase the securities held by Kingsbridge for a price equal to the
volume weighted average price on the trading day prior to such period of ineffectiveness.
We may also elect to pay such liquidated damages in shares of common stock valued at the
market value on the first trading day after such permitted suspension ends. </FONT></P>

as indemnification for liabilities arising under the Securities Act of 1933 may be
permitted to our directors, officers and  controlling persons pursuant to the foregoing
provisions, or otherwise, we have been advised that in the opinion of the SEC such
indemnification is  against public policy as expressed in the Securities Act of 1933 and
is, therefore, unenforceable.  In the event that a claim for indemnification  against
such liabilities (other than our payment of expenses incurred or paid by one of our
directors, officers or controlling persons in the  successful defense of any action, suit
or proceeding) is asserted by such director, officer or controlling person in connection
with the securities  being registered, we will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of  appropriate
jurisdiction the question whether such indemnification by it is against public policy as
expressed in the Securities Act of 1933 and will  be governed by the final adjudication
of such issue. </FONT></P>

                                     BYLAWS
                                       OF
                         AMERICAN TECHNOLOGY CORPORATION
                            (A DELAWARE CORPORATION)
                    (AS AMENDED AND RESTATED APRIL 13, 2004)

                                   ARTICLE I
                                     GENERAL

         1.01. APPLICABILITY. These Bylaws provide rules for conducting the
business of this corporation (the "COMPANY"). Every shareholder and person who
subsequently becomes a shareholder, the Board of Directors, Committees and
Officers of the Company shall comply with these Bylaws, as amended from time to
time. All Bylaws and resolutions heretofore adopted by the Board of Directors
are hereby repealed, to the extent in conflict with the provisions of these
Bylaws.

         1.02. OFFICES. The principal office of Company shall be selected by the
Board of Directors from time to time and may be within or without the State of
Delaware. The Company may have such other offices, within or without the State
of Delaware, as the Board of Directors may, from time to time, determine. The
registered office of the Company required by the General Corporation Law of
Delaware to be maintained in Delaware may be, but need not be, identical with
the principal office if in Delaware, and the address of the registered office
may be changed from time to time by the Board of Directors.

         1.03. DEFINITION OF TERMS. Terms defined in the Company's Certificate
of Incorporation, as amended and restated from time to time in effect (the
"CHARTER"), shall have the same meanings when used in these Bylaws.

                                   ARTICLE II
                         STOCK AND THE TRANSFER THEREOF

         2.01. STOCK CERTIFICATES. The shares of the Company's capital stock
shall be represented by consecutively numbered certificates signed by the
President or a Vice President and the Secretary or Assistant Secretary of the
Company, and sealed with the seal of the Company, or a facsimile thereof. If
certificates are signed by a transfer agent and registrar other than the Company
or an employee thereof, the signatures of the officers of the Company may be
facsimile. In case any officer who has signed (by real or facsimile signature) a
certificate shall have ceased to hold such office before the certificate is
issued it may be issued by the Company with the same effect as if he continued
to hold such office on the date of issue. Each certificate representing shares
shall state upon the face thereof: (i) that the Company is organized under the
laws of the State of Delaware; (ii) the name of the person to whom issued; (iii)
the number, class and series (if any) of shares which such certificate
represents; and (iv) the par value, if any, of the shares represented by such
certificate, or a statement that the shares have no par value.

         If any class or series of shares is subject to special powers,
designations, preferences or relative, participating or other special rights,
then such (together with all qualifications, limitations or restrictions of such
preferences or rights) shall be set forth in full or summarized on the
certificate representing such class or series. Moreover, each certificate shall
state that the Company will furnish, without charge, to the registered holder of
the shares represented by such certificate who so requests a statement setting
forth such information in full.

                                      -1-


<PAGE>

         Each certificate also shall set forth restrictions upon transfer, if
any, or a reference thereto, as shall be adopted by the Board of Directors or by
the shareholders, or as may be contained in this Article II. Any shares issued
without registration under the Securities Act of 1933, as amended, shall bear a
legend restricting transfer unless such shares are registered under such act or
an exemption from registration is available for a proposed transfer.

         2.02. CONSIDERATION FOR SHARES. Shares shall be issued for such
consideration or considerations as shall be fixed from time to time by the Board
of Directors. Treasury shares may be disposed of by the Company for such
consideration as may be fixed from time to time by the Board of Directors. No
shares shall be issued for less than the par value thereof. The consideration
for the issuance of shares may be paid, in whole or in part, in money, in other
property, tangible or intangible, or in labor or services actually received by
or performed for the Company or for its benefit or in its formation or
reorganization, or as otherwise permitted in the Charter.

         2.03. LOST CERTIFICATES. The Board of Directors may direct a new
certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the Company alleged to have been lost or
destroyed, upon the making of an affidavit of that fact by the person claiming
the certificate of stock to be lost, and the Board of Directors when authorizing
such issue of a new certificate or certificates may in its discretion, and as a
condition precedent to the issuance thereof, require the owner of such lost or
destroyed certificate or certificates or his legal representative to advertise
the same in such manner as it shall require, and/or furnish to the Company a
bond in such sum as it may direct, as indemnity against any claim that may be
made against the Company. Except as hereinabove in this section provided, no new
certificate or certificates evidencing shares of stock shall be issued unless
and until the old certificate or certificates, in lieu of which the new
certificate or certificates are issued, shall be surrendered for cancellation.

         2.04. REGISTERED HOLDER AS OWNER. The Company shall be entitled to
treat the registered holder of any shares of the Company as the owner of such
shares, and shall not be bound to recognize any equitable or other claim to, or
interest in, such shares or rights deriving from such shares, unless and until
such purchaser, assignee, transferee or other person becomes the registered
holder of such shares, whether or not the Company shall have either actual or
constructive notice of the interests of such purchaser, assignee, or transferee
or other person. The purchaser, assignee, or transferee of any of the shares of
the Company shall not be entitled to receive notice of the meetings of the
shareholders; to vote at such meetings; to examine a list of the shareholders;
to be paid dividends or other sums payable to shareholders; or to own, enjoy and
exercise any other property or rights deriving from such shares against the
Company, until such purchaser, assignee, or transferee has become the registered
holder of such shares.


                                      -2-


<PAGE>

         2.05. REVERSIONS. Cash, property or share dividends, shares issuable to
shareholders in connection with a reclassification of stock, and the redemption
price of redeemed shares, which are not claimed by the shareholders entitled
thereto within TWO years after the dividend or redemption price became payable
or the shares became issuable, despite reasonable efforts by the Company to pay
the dividend or redemption price or deliver the certificate(s) for the shares to
such shareholders within such time shall, at the expiration of such time, revert
in full ownership to the Company, and the Company's obligation to pay any such
dividend or redemption price or issue such shares, as the case may be, shall
thereupon cease; provided, that the Board of Directors may at any time and for
any reason satisfactory to it, but need not, authorize (i) payment of the amount
of cash or property dividend or (ii) issuance of any shares, ownership of which
has reverted to the Company pursuant to this Section of Article II, to the
person or entity who or which would be entitled thereto had such reversion not
occurred.

         2.06. RETURNED CERTIFICATES. All certificates for shares changed or
returned to the Company for transfer shall be marked by the Secretary
"CANCELLED," with the date of cancellation, and the transaction shall be
immediately recorded in the certificate book opposite the memorandum of their
issue. The returned certificate may be inserted in the certificate book.

         2.07. TRANSFER OF SHARES. Upon surrender to the Company or to a
transfer agent of the Company of a certificate of stock endorsed or accompanied
by proper evidence of succession, assignment or authority to transfer, and such
documentary stamps as may be required by law, it shall be the duty of the
Company to issue a new certificate, upon payment by the transferree of such
nominal charge therefor as the Company or its transfer agent may impose. Each
such transfer of stock shall be entered on the stock book of the Company.
Respecting any securities issued in reliance upon Rule 903 of Regulation S of
the Securities and Exchange Commission at any time when the Company is not a
"reporting issuer" as defined in Regulation S, no transfer of such securities
shall be registered unless made in accordance with the provisions of Regulation
S, except where foreign law prevents the Company from refusing to register the
securities.

         At any time when the Company has appointed a transfer agent for its
shares, this paragraph shall apply. A transfer of shares evidenced by a
certificate bearing a standard form of legend which restricts transfer of the
shares (except in the event of registration or the availability of an exemption
under the Securities Act of 1933) shall not require the Company's consent if the
shares to be sold are proposed to be sold in compliance with either Rule 144,
Rule 701 or Rule 904 of Regulation S of the Securities and Exchange Commission
and the transfer is accompanied by an opinion of counsel (which need not be the
Company's counsel) which states that the proposed transfer will comply with the
applicable rule or regulation being relied upon for transfer. In view of
potential liability to the Company and its officers and directors for
interfering without firm and clear legal grounds in the making of, or delaying,
any sale of the Company's shares pursuant to Rules 144, 701 or 904, it is
declared to be the Company's policy not to interfere with, object to or hinder,
in any way, any transfer proposed to be made pursuant to either of Rules 144,
701 or 904, if accompanied by an opinion of counsel which states that the
proposed sale will, in the manner proposed to be made, comply with the
applicable rule or regulation being relied upon for sale. The Company shall be
deemed automatically to have consented to any transfer which complies with the
immediately preceding sentence.


                                      -3-


<PAGE>

         2.08. TRANSFER AGENT. The Board of Directors shall have power to
appoint one or more transfer agents and registrars for the transfer and
registration of certificates of stock of any class, and may require that stock
certificates shall be counter signed and registered by one or more of such
transfer Agents and registrars. Any powers or duties with respect to the
transfer and registration of certificates may be delegated to the transfer agent
and registrar.

                                  ARTICLE III
                          MEETINGS OF THE SHAREHOLDERS

         3.01. ANNUAL MEETING.

             (a) The annual meeting of the shareholders of the Company, for the
purpose of election of Directors and for such other business as may lawfully
come before it, shall be held on such date and at such time as may be designated
from time to time by the Board of Directors.

             (b) At an annual meeting of the shareholders, only such business
shall be conducted as shall have been properly brought before the meeting. To be
properly brought before an annual meeting, business must be: (A) specified in
the notice of meeting (or any supplement thereto) given by or at the direction
of the Board of Directors, (B) otherwise properly brought before the meeting by
or at the direction of the Board of Directors, or (C) otherwise properly brought
before the meeting by a shareholder. For business to be properly brought before
an annual meeting by a shareholder, the shareholder must have given timely
notice thereof in writing to the Secretary of the Company. To be timely, a
shareholder's notice must be delivered to or mailed and received at the
principal executive offices of the Company not later than the close of business
on the sixtieth (60th) day nor earlier than the close of business on the
ninetieth (90th) day prior to the first anniversary of the preceding year's
annual meeting; provided, however, that in the event that no annual meeting was
held in the previous year or the date of the annual meeting has been changed by
more than thirty (30) days from the date contemplated at the time of the
previous year's proxy statement, notice by the shareholder to be timely must be
so received not earlier than the close of business on the ninetieth (90th) day
prior to such annual meeting and not later than the close of business on the
later of the sixtieth (60th) day prior to such annual meeting or, in the event
public announcement of the date of such annual meeting is first made by the
Company fewer than seventy (70) days prior to the date of such annual meeting,
the close of business on the tenth (10th) day following the day on which public
announcement of the date of such meeting is first made by the Company. A
shareholder's notice to the Secretary shall set forth as to each matter the
shareholder proposes to bring before the annual meeting: (i) a brief description
of the business desired to be brought before the annual meeting and the reasons
for conducting such business at the annual meeting, (ii) the name and address,
as they appear on the Company's books, of the shareholder proposing such
business, (iii) the class and number of shares of the Company which are
beneficially owned by the shareholder, (iv) any material interest of the
shareholder in such business and (v) any other information that is required to
be provided by the shareholder pursuant to Regulation 14A under the Securities
Exchange Act of 1934, as amended (the "1934 Act"), in his capacity as a
proponent to a shareholder proposal. Notwithstanding the foregoing, in order to
include information with respect to a shareholder proposal in the proxy
statement and form of proxy for a shareholders' meeting, shareholders must
provide notice as required by the regulations promulgated under the 1934 Act.
Notwithstanding anything in these Bylaws to the contrary, no business shall be
conducted at any annual meeting except in accordance with the procedures set
forth in this paragraph (b). The chairman of the annual meeting shall, if the
facts warrant, determine and declare at the meeting that business was not
properly brought before the meeting and in accordance with the provisions of
this paragraph (b), and, if he should so determine, he shall so declare at the
meeting that any such business not properly brought before the meeting shall not
be transacted.

             (c) Only persons who are nominated in accordance with the
procedures set forth in this paragraph (c) shall be eligible for election as
Directors. Nominations of persons for election to the Board of Directors of the
Company may be made at a meeting of shareholders by or at the direction of the
Board of Directors or by any shareholder of the Company entitled to vote in the
election of Directors at the meeting who complies with the notice procedures set
forth in this paragraph (c). Such nominations, other than those made by or at
the direction of the Board of Directors or a duly authorized committee thereof,
shall be made pursuant to timely notice in writing to the Secretary of the
Company in accordance with the provisions of paragraph (b) of this Section 3.01.
Such shareholder's notice shall set forth (i) as to each person, if any, whom
the shareholder proposes to nominate for election or re-election as a Director:
(A) the name, age, business address and residence address of such person, (B)
the principal occupation or employment of such person, (C) the class and number
of shares of the Company that are beneficially owned by such person, (D) a
description of all arrangements or understandings between the shareholder and
each nominee and any other person or persons (naming such person or persons)
pursuant to which the nominations are to be made by the shareholder, and (E) any
other information relating to such person that is required to be disclosed in
solicitations of proxies for elections of Directors, or is otherwise required,
in each case pursuant to Regulation 14A under the 1934 Act (including without
limitation such person's written consent to being named in the proxy statement,
if any, as a nominee and to serving as a Director if elected); and (ii) as to
such shareholder giving notice, the information required to be provided pursuant
to paragraph (b) of this Section 3.01. At the request of the Board of Directors,
any person nominated by a shareholder for election as a Director shall furnish
to the Secretary of the Company that information required to be set forth in the
shareholder's notice of nomination which pertains to the nominee. No person
shall be eligible for election as a Director of the Company unless nominated in
accordance with the procedures set forth in this paragraph (c). The chairman of
the annual meeting shall, if the facts warrant, determine and declare at the
meeting that a nomination was not made in accordance with the procedures
prescribed by these Bylaws, and if he should so determine, he shall so declare
at the meeting, and the defective nomination shall be disregarded.

             (d) For purposes of this Section 301, "public announcement" shall
mean disclosure in a press release reported by the Dow Jones News Service,
Associated Press or comparable national news service or in a document publicly
filed by the Company with the Securities and Exchange Commission pursuant to
Section 13, 14 or 15(d) of the 1934 Act.

         3.02. SPECIAL MEETINGS.

             (a) Special meetings of the shareholders of the Company may be
called, for any purpose or purposes, by (i) the Chairman of the Board of
Directors, (ii) the Chief Executive Officer, (iii) the Board of Directors
pursuant to a resolution adopted by a majority of the total number of authorized
Directors (whether or not there exist any vacancies in previously authorized
directorships at the time any such resolution is presented to the Board of
Directors for adoption) or (iv) by the holders of shares entitled to cast not
less than 10 percent (10%) of the votes at the meeting, and shall be held at
such place, on such date, and at such time as the Board of Directors shall fix.


                                      -5-


<PAGE>

             (b) If a special meeting is properly called by any person or
persons other than the Board of Directors, the request shall be in writing,
specifying the general nature of the business proposed to be transacted, and
shall be delivered personally or sent by registered mail or by telegraphic or
other facsimile transmission to the Chairman of the Board of Directors, the
Chief Executive Officer, or the Secretary of the Company. No business may be
transacted at such special meeting otherwise than specified in such notice. The
Board of Directors shall determine the time and place of such special meeting,
which shall be held not less than thirty-five (35) nor more than one hundred
twenty (120) days after the date of the receipt of the request. Upon
determination of the time and place of the meeting, the officer receiving the
request shall cause notice to be given to the shareholders entitled to vote, in
accordance with the provisions of Section 3.03 of these Bylaws. If the notice is
not given within sixty (60) days after the receipt of the request, the person or
persons properly requesting the meeting may set the time and place of the
meeting and give the notice. Nothing contained in this paragraph (b) shall be
construed as limiting, fixing, or affecting the time when a meeting of
shareholders called by action of the Board of Directors may be held.

         3.03. NOTICE OF MEETINGS. Except as otherwise provided by law, the
Charter or these Bylaws, written notice of any annual or special meeting of the
shareholders shall state the place, date, and time thereof and, in the case of a
special meeting, the purpose or purposes for which the meeting is called, shall
be given to each shareholder of record entitled to vote at such meeting not
fewer than 10 nor more than 60 days prior to the meeting by any means permitted
in Section 9.01 hereof. No business other than that specified in the notice of a
special meeting shall be transacted at any such special meeting.

         3.04. RECORD DATE. In order that the Company may determine shareholders
of record who are entitled (i) to notice of or to vote at any shareholders
meeting or adjournment thereof, (ii) to express written consent to corporate
action in lieu of a meeting, (iii) to receive payment of any dividend or other
distribution, or (iv) to allotment of any rights or to exercise any rights in
respect of any change, conversion or exchange of stock, or in order that the
Company may make a determination of shareholders of record for any other lawful
purpose, the Board of Directors may fix in advance a date as the record date for
any such determination. Such date shall not be more than 60 days, and in case of
a meeting of shareholders, not less than 10 days prior to the date on which the
particular action, requiring such determination of shareholders, is to be taken,
and in no event may the record date precede the date upon which the Directors
adopt a resolution fixing the record date.

         If no record date is fixed for the determination of shareholders
entitled to notice of or to vote at a meeting of shareholders, or shareholders
entitled to receive payment of a dividend, the date on which notice of the
meeting is given (as defined in Section 9.01 hereof) or the date on which the
resolution of the Board of Directors declaring such dividend is adopted, as the
case may be, shall be the record date for such determination of the
shareholders. When a determination of shareholders entitled to vote at any
meeting of shareholders has been made as provided in this Section such
determination shall apply to any adjournment thereof, unless the Board of
Directors fixes a new record date for the adjournment. The record date for
determining shareholders entitled to consent to corporate actions without a
meeting shall be fixed as provided in Section 3.12 hereof.

any meeting of shareholders, the officer or transfer agent in charge of the
Company's stock transfer books shall prepare a complete alphabetical list of the
shareholders entitled to vote at such meeting, which list shows the address of
each shareholder and the number of shares registered in his or her name. The
list so prepared shall be maintained at the corporate offices of the Company and
shall be open to inspection by any shareholder, for any purpose germane to the
meeting, at any time during usual business hours during a period of no fewer
than 10 days prior to the meeting. The list shall also be produced and kept open
at any shareholders meeting and, except as otherwise provided by law, may be

         3.06. QUORUM; ADJOURNMENTS.

             (a) The holders of a majority of the total voting power at any
shareholders meeting present in person or by proxy shall be necessary to and
shall constitute a quorum for the transaction of business at all shareholders
meetings, except as otherwise provided by law or by the Charter.

             (b) If a quorum is not present in person or by proxy at any
shareholders meeting, a majority of the voting shares present or represented
shall have the power to adjourn the meeting from time to time to the same or
another place within 30 days thereof and no further notice of such adjourned
meeting need be given if the time and place thereof are announced at the meeting
at which the adjournment is taken.

             (c) Even if a quorum is present in person or by proxy at any
shareholders meeting, a majority of the voting shares present or represented
shall have the power to adjourn the meeting from time to time, for good cause,
without notice of the adjourned meeting if the time and place thereof are
announced at the meeting at which the adjournment is taken, until a new date
which is not more than 30 days after the date of the original meeting.

             (d) Any business which might have been transacted at a shareholders
meeting as originally called may be transacted at any meeting held after
adjournment as provided in this Section 3.06 at which reconvened meeting a
quorum is present in person or by proxy. Anything in paragraph (b) of this
Section to the contrary notwithstanding, if an adjournment is for more than 30
days, or if after an adjournment a new record date is fixed for the adjourned
meeting, notice of the adjourned meeting shall be given to each shareholder of
record entitled to vote thereat.

             (e) The shareholders present at a duly called meeting may continue
to transact business until adjournment, notwithstanding the withdrawal of enough
shareholders to leave less than a quorum.

<PAGE>

         3.07. PROXIES. At all meetings of shareholders, a shareholder may vote
by proxy, executed in writing by the shareholder or by his duly authorized
attorney in fact. Any proxyholder shall be authorized to sign, on the
shareholder's behalf, any written consent for shareholder action taken in lieu
of a meeting. Such proxy shall be filed with the Secretary of the Company before
or at the time of the meeting. No proxy shall be valid after three (3) years
from the date of its execution, unless otherwise provided in the proxy.

         3.08. VOTING OF SHARES. At any shareholders meeting every shareholder
having the right to vote shall be entitled to vote in person or by proxy. Except
as otherwise provided by law, by the Articles or in the Board resolution
authorizing the issuance of shares, each shareholder of record shall be entitled
to one vote (on each matter submitted to a vote) for each share of capital stock
registered in his, her or its name on the Company's books. Except as otherwise
provided by law or by the Articles, all matters submitted to the shareholders
for approval shall be determined by a majority of the votes cast (not counting
abstentions) at a legal meeting commenced with a quorum.

         3.09. VOTING OF SHARES BY CERTAIN HOLDERS. Neither treasury shares, nor
shares of its own stock held by the Company in a fiduciary capacity, nor shares
held by another corporation if the majority of the shares entitled to vote for
the election of directors of such other corporation is held by the Company,
shall be voted at any meeting or counted in determining the total number of
outstanding shares at any given time.

         Shares standing in the name of another corporation, domestic or
foreign, may be voted by such officer, agent, or proxy as the bylaws of such
corporation may prescribe, or, in the absence of such provision, as the board of
directors of such corporation may determine.

         Shares held by an administrator, executor, personal representative,
guardian, or conservator may be voted by him, either in person or by proxy,
without a transfer of such shares into his name. Shares standing in the name of
a trustee may be voted by him, either in person or by proxy, but no trustee
shall be entitled to vote shares hold by him without a transfer of such shares
into his name.

         Shares standing in the name of a receiver may be voted by such
receiver, and shares held by or under the control of a receiver may be voted by
such receiver without the transfer thereof into his name if authority to do so
be contained in an appropriate order of the court by which such receiver was
appointed.

         A shareholder whose shares are pledged shall be entitled to vote such
shares until the shares have been transferred into the name of the pledgee, and
thereafter the pledgee shall be entitled to vote the shares so transferred.

         3.10. CHAIRMAN. The Chairman of the Board of Directors of the Company,
if there is one, or is his absence, the President, shall act as chairman at all
meetings of shareholders.

         3.11. MANNER OF SHAREHOLDER VOTING. Voting at any shareholders meeting
shall be oral or by show of hands; PROVIDED HOWEVER, that voting shall be by
written ballot if such demand is made by any shareholder present in person or by
proxy and entitled to vote.

                                      -8-


<PAGE>

         3.12. ACTION BY SHAREHOLDERS WITHOUT A MEETING RECORD DATE. Any action
required or permitted to be taken at a meeting of the shareholders may be taken
without a meeting, without prior notice and without a vote, if a consent in
writing, setting forth the action so taken, shall be signed by a majority of the
total voting power; PROVIDED, that where an action requires a greater proportion
of the total voting power, then the consent shall be signed by such greater
proportion. No written consent will be effective unless written consents, signed
by a sufficient proportion of shareholders to take action, are delivered to the
Company within sixty (60) days of the date of the earliest such consent. Such
consent shall have the same force and effect as a vote of the shareholders, and
may be stated as such in any document filed with the Secretary of State of
Delaware under the General Corporation Law of Delaware. Prompt notice of such
action by written consent of less than all shareholders entitled to vote shall
be given to all shareholders who have not consented in writing to the action
taken.

         The record date for determining shareholders entitled to consent to
corporate actions in writing without a meeting (the "CONSENT RECORD DATE") shall
not precede, and shall not be more than ten (10) days after, the date upon which
the resolution fixing the record date was adopted. However, if no consent record
date is fixed, the consent record date shall be, respectively, (i) if prior
action by the Board of Directors IS required under the General Corporation Law
of Delaware for the consent to be validly taken, the close of business on the
day on which the Board of Directors adopts the resolution taking such prior
action; and (ii) if prior action by the Board of Directors IS NOT so required,
the first date on which a properly signed and dated consent setting forth the
action taken or proposed to be taken is delivered as required above.

         3.13. PRESIDING OFFICERS; ORDER OF BUSINESS.

             (a) Shareholders meetings shall be presided over by the Chairman of
the Board; or if the Chairman (and Vice Chairman) is not present, by the
President; or if the President is not present, by a Vice President; or if a Vice
President is not present, by such person chosen by the Board of Directors; or if
none, by a chairperson to be chosen at the meeting by shareholders present in
person or by proxy who own a majority of the voting power present. The Secretary
of a shareholders meeting shall be the Secretary of the Company; or if the
Secretary is not present, an Assistant Secretary, or if an Assistant Secretary
is not present, such person as may be chosen by the Board of Directors; or if
none, by such person who is chosen by the chairperson at the meeting.

             (b) The following order of business, unless otherwise ordered at
the shareholders meeting by the chairperson thereof, shall be observed as far as
practicable and consistent with the purposes of the meeting:

             1.   Calling of the shareholders' meeting to order.

             2.   Presentation of proof of mailing of the notice of the meeting

             5.   Reading and approval (or waiver thereof) of the minutes of the
                  previous meeting of shareholders.

             6.   Reports, if any, of officers.

             7.   Election of directors, if the meeting is an annual meeting or
                  a meeting called for such purpose.

             8.   Consideration of the specific purpose or purposes for which
                  the meeting has been called, other than election of directors.

             9.   Transaction of such other business as may properly come before
                  the meeting.

             10.  Adjournment.

         3.14. ANNUAL REPORT. The President of the Company shall prepare an
annual report which will set forth a statement of affairs of the Company as of
the end of its last fiscal year, including a balance sheet, an income statement
and a statement of changes in financial position, which need not be audited, and
present them at the annual meeting of shareholders. Failure to prepare or
present an annual report shall not affect the validity of any shareholder

                  Re:      Registration Statement on Form S-3
                           ----------------------------------

Ladies and Gentlemen:

                  We have acted as special counsel to American Technology
Corporation, a Delaware corporation (the "Company"), in connection with the
filing of a registration statement on Form S-3 (the "Registration Statement")
under the Securities Act of 1933, as amended, covering the offering for resale
of up to 3,959,782 shares of the Company's common stock, par value $0.00001 per
share (the "Common Stock"), by the selling stockholder named therein (the
"Selling Stockholder"), which includes (i) up to 3,684,782 shares of Common
Stock (the "Shares") which the Company may issue from time to time after the
Registration Statement becomes effective pursuant to an executed and delivered
purchase agreement (the "Purchase Agreement"); and (ii) up to 275,000 shares of
Common Stock (the "Warrant Shares") issuable upon the exercise of an issued and
outstanding warrant (the "Warrant"). This opinion is being furnished in
accordance with the requirements of Item 16 of Form S-3 and Item 601(b)(5)(i) of
Regulation S-K.

                  In connection with this opinion, we have reviewed the
Registration Statement, the Company's charter documents, the resolutions adopted
by the Board of Directors of the Company on December 10, 2004 (the
"Resolutions"), certificates of government officials and such other documents,
records, certificates, memoranda and other instruments as we deem necessary as a
basis for this opinion. With respect to the foregoing documents, we have assumed
the genuineness of all signatures, the authenticity of all documents submitted
to us as originals and the conformity to originals of all documents submitted to
us as certified or reproduced copies. We have also assumed that the specimen
common stock certificate submitted to us will conform to the common stock
certificates issued to represent the Shares or Warrant Shares (the "Share
Certificates"), that the Share Certificates will be duly executed by the Company
and countersigned by the transfer agent therefor in accordance with Section 158
of the Delaware General Corporation Law, that shares currently reserved will
remain available for the issuance of the Shares or Warrant Shares, and that the
Company's charter documents and Resolutions will not be amended or otherwise
modified prior to the issuance of any Shares or Warrant Shares. We have obtained
from the officers of the Company certificates as to certain factual matters and,
insofar as this opinion is based on matters of fact, we have relied on such
certificates without independent investigation.

                  Based on the foregoing review, and in reliance thereon, we are
of the opinion that if, as and when the Shares and Warrant Shares are issued and
delivered by the Company in accordance with the terms of the Purchase Agreement
and Warrant, respectively, including without limitation payment in full of the
consideration therefor, the Shares and Warrant Shares will be validly issued,
fully paid and nonassessable.

                  We consent to the filing of this opinion letter as Exhibit 5.1
to the Registration Statement and the naming of our firm in the "Legal Matters"
portion of the prospectus included in the Registration Statement.

                  We express no opinion as to matters governed by any laws other
than the Delaware General Corporation Law, the applicable provisions of the
Delaware Constitution and reported decisions of the Delaware courts interpreting
these laws.

                  This opinion letter is rendered as of the date first written
above, and we disclaim any obligation to advise you of facts, circumstances,
events or developments which hereafter may be brought to our attention and which
may alter, affect or modify the opinion expressed herein. Our opinion is
expressly limited to the matters set forth above, and we render no opinion,
whether by implication or otherwise, as to any other matters relating to the
Company, the Shares or the Warrant Shares.


                                     Respectfully submitted,

                                     /s/ Sheppard, Mullin, Richter & Hampton LLP
