Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
60 words
An acoustic system for dispostion proximate to an acoustical boundary comprising at least one acoustic transducer, with a diaphragm, for directing acoustic energy away from the boundary and an acoustic reflector surface extending from proximate to the center of said diaphragm to said boundary without substantial acoustic discontinuity along its extent and at the junction of said boundary and surface.
Claim 2
Dependent Claim
60 words
An acoustic system for dispostion proximate to an acoustical boundary comprising at least one acoustic transducer, with a diaphragm, for directing acoustic energy away from the boundary and an acoustic reflector surface extending from proximate to the center of said diaphragm to said boundary without substantial acoustic discontinuity along its extent and at the junction of said boundary and surface.
Claim 3
Dependent Claim
55 words
The system of claim 1 in which said boundary includes at least two areas and said surface includes at least two sections which extend from proximate to the center of said diaphragm to the corresponding area of the boundary without substantial acoustic discontinuity along their extent and at the junctions of said boundary and sections.
Claim 4
Dependent Claim
15 words
The system of claim 1 in which said surface is acoustically sealed to said transducer.
Claim 5
Dependent Claim
11 words
The system of claim 1 in which said surface is smooth.
Claim 6
Dependent Claim
22 words
The system of claim 1 in which the portion of said surface proximate to said transducer extends in front of said transducer.
Claim 7
Dependent Claim
54 words
The system of claim 1 in which said boundary includes at least two areas and said surface includes at least one section extending from proximate to the center of said diaphragm to the corresponding area of the boundary without substantial acoustic discontinuity along its extent and at the junction of said boundary and surface.
Claim 8
Dependent Claim
22 words
The system of claim 1 in which at least a portion of the frequency range of said acoustic system is above 20kHz.
Claim 9
Dependent Claim
14 words
The system of claim 1 in which there is at least two acoustic transducers.
Claim 10
Dependent Claim
75 words
An acoustic system for disposition proximate to an acoustic boundary having two areas comprising at least one acoustic transducer, with a diaphragm, for directing acoustic energy away from said boundary and an acoustic reflector surface including two sections, each section extending from proximate to the center of said diaphragm to the corresponding one of the area of the boundary without substantial acoustic discontinuity along its extent and at the junction of said boundary and surface.
Claim 11
Dependent Claim
75 words
An acoustic system for disposition proximate to an acoustic boundary having two areas comprising at least one acoustic transducer, with a diaphragm, for directing acoustic energy away from said boundary and an acoustic reflector surface including two sections, each section extending from proximate to the center of said diaphragm to the corresponding one of the area of the boundary without substantial acoustic discontinuity along its extent and at the junction of said boundary and surface.
Claim 12
Dependent Claim
72 words
An acoustic system for disposition proximate to an acoustic boundary having three areas comprsing at least one acoustic transducer, with a diaphragm, for directing acoustic energy away from said boundary and an acoustic reflector surface including three sections, each section extending from proximate to the center of said diaphragm to the corresponding area of the boundary without substantial acoustical discontinuity along its extent and at the junction of said boundary and surface.
Claim 13
Dependent Claim
72 words
An acoustic system for disposition proximate to an acoustic boundary having three areas comprsing at least one acoustic transducer, with a diaphragm, for directing acoustic energy away from said boundary and an acoustic reflector surface including three sections, each section extending from proximate to the center of said diaphragm to the corresponding area of the boundary without substantial acoustical discontinuity along its extent and at the junction of said boundary and surface.
Claim 14
Dependent Claim
62 words
An acoustic system for disposition proximate to an acoustical boundary comprising at least two acoustic transducers, each having a diaphragm, for directing acoustic energy away from said boundary and an acoustic reflector surface extending from proximate to the center of each said diaphragm to the boundary without substantial acoustic discontinuity along its extent and at the junction of said boundary and surface.
Claim 15
Dependent Claim
62 words
An acoustic system for disposition proximate to an acoustical boundary comprising at least two acoustic transducers, each having a diaphragm, for directing acoustic energy away from said boundary and an acoustic reflector surface extending from proximate to the center of each said diaphragm to the boundary without substantial acoustic discontinuity along its extent and at the junction of said boundary and surface.
Claim 16
Dependent Claim
48 words
The system of claim 11 in which said boundary includes at least two areas and said surface includes at least two sections, each section extending to the corresponding area of the boundary without substantial acoustic discontinuity along its extent and at the junction of said boundary and surface.
