1. Infringement Claim Chart for U.S. Pat. No. US7130430B2 v. Bose (“Defendant”)

Claim 3 Evidence

3. A speaker 

system for 

producing 

localized regions

of sound 

comprising:

The Bose MSA12X Array Loudspeaker is speaker a system for producing localized regions

of sound.

For example, the Bose MSA12X Array Loudspeaker array produces an acoustic beam of

sound. The beam can be aimed at the listening audience while keeping it away from

other surfaces (e.g. ceiling and walls) that may cause echoes and reverberation.

a multiplicity of 

audio frequency 

speakers;

The Bose MSA12X Array Loudspeaker array includes a multiplicity of audio frequency

speakers.

For example, Bose MSA12X Array Loudspeaker has an array of twelve individual audio

loudspeakers mounted along the axial direction of the loudspeaker.

at least one 

defined sound 

target spaced 

from each of the

speakers of the 

multiplicity of 

speakers, 

The Bose MSA12X Array Loudspeaker has at least one defined sound target spaced from

each of the speakers of the multiplicity of speakers. Each speaker has a means for

applying a time varying audio drive voltage which is substantially identical, except that

each audio drive voltage is offset in time by an amount which is related to the distance

between each speaker and the defined sound target. So that substantially identical

sound from each speaker reaches the sound target at the same time.

wherein each 

speaker has a

which is 

substantially 

identical, except

that each audio

from each 

speaker reaches

at the same 

time; and

For example, each of the Bose MSA12X Array Loudspeaker speakers is connected to an

audio amplifier. An audio signal is provided to each speaker via the speaker’s respective

amplifier. The audio signal is delayed more for speakers closer to the position at which

the acoustic beam is aimed and delayed less for speakers farther from that position.

wherein the 

means for 

applying a time 

varying audio 

drive voltage 

includes a class 

D amplifier.

The means for applying a time varying audio drive voltage includes amplifier.

For example, a twelve-channel audio amplifier is used to drive the Bose MSA12X Array

Loudspeaker.
