Abstract

Abstract High quality stereo sound dispersion is obtained through the use of a speaker cabinet having three tiers of speakers which are effectively sound insulated from one another. The topmost and bottommost tiers have speakers which are oriented in divergent directions from one another, while the intermediate tier has speakers which are unidirectionally oriented. Horizontal sound panels are provided between the respective tiers of speakers to accomplish the sound insulating effect, and the speakers themselves are mounted in vertical panels which form walls associated with sound compartments. In this respect, the divergently oriented speakers are positioned within walls of triangularly shaped sound compartments, while the unidirectionally oriented speakers are contained within a wall of a rectangularly shaped sound compartment. The respective sound compartments are sealed airtight and are filled with acoustical fiber glass to create the desired sound enhancement characteristics. A felt material is provided as a covering over the horizontal sound panels so as to further modify the tonal effects of the projected sound.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 143 words
An acoustic system comprising: a speaker support means having a plurality of tiers forming airtight spaces containing a plurality of sound dispersing speakers positioned within said speaker support means, a topmost tier of said speakers and a bottommost tier of said speakers each utilizing speakers divergently aligned with one another; sound chamber means associated with said airtight spaces of said plurality of sound dispersing speakers, said sound chamber means serving to modify the tonal quality of sound emitted by said plurality of speakers; sound obstructing means including material covering means performing as a sound insulation means associated with said support means and forming sound panel means positioned between adjacent tiers of said plurality of tiers serving to selectively prevent an interference of dispersed sound between said plurality of speakers; and sound directing means serving to direct said dispersed sound in a desired direction.
Claim 2
Dependent Claim 143 words
An acoustic system comprising: a speaker support means having a plurality of tiers forming airtight spaces containing a plurality of sound dispersing speakers positioned within said speaker support means, a topmost tier of said speakers and a bottommost tier of said speakers each utilizing speakers divergently aligned with one another; sound chamber means associated with said airtight spaces of said plurality of sound dispersing speakers, said sound chamber means serving to modify the tonal quality of sound emitted by said plurality of speakers; sound obstructing means including material covering means performing as a sound insulation means associated with said support means and forming sound panel means positioned between adjacent tiers of said plurality of tiers serving to selectively prevent an interference of dispersed sound between said plurality of speakers; and sound directing means serving to direct said dispersed sound in a desired direction.
Claim 3
Dependent Claim 34 words
The acoustic system as described in claim 1, wherein said plurality of tiers includes at least three tiers, said at least three tiers being sound insulated from one another by said sound obstructing means.
Claim 4
Dependent Claim 22 words
The acoustic system as described in claim 1, wherein four speakers are provided in each of said plurality of tiers of speakers.
Claim 5
Dependent Claim 19 words
The acoustic system as described in claim 1, wherein an intermediate tier of speakers has four speakers unidirectionally aligned.
Claim 6
Dependent Claim 45 words
The acoustic system as described in claim 1, wherein said sound directing means includes wall members into which said plurality of speakers are fixedly mounted, said wall members being positioned so as to cause an alignment of said plurality of speakers in a desired direction.
Claim 7
Dependent Claim 46 words
The acoustic system as described in claim 4, wherein said sound chamber means associated with said topmost and bottommost divergently aligned tiers of speakers are of a triangular shape and said sound chamber means associated with said intermediate unidirectionally aligned speakers is of a rectangular shape.
Claim 8
Dependent Claim 19 words
The acoustic system as described in claim 1, wherein said sound chamber means are packed with acoustical fiber glass.
Claim 9
Dependent Claim 326 words
A stereo speaker support means in a cabinet comprising: a base member, said base member comprising a sound insulating horizontal panel; a top member, said top member comprising a horizontal sound panel; a back wall member, said back wall member serving to connect said base member with said top member; a first sound panel horizontally aligned with and positioned between said top member and said base member; a second sound panel horizontally aligned with and positioned between said top member and said base member; a first group of stereo speakers positioned between said top member and said first sound panel, said first group of stereo speakers being divergently aligned with respect to one another; a second group of stereo speakers positioned between said first sound panel and said second sound panel, said second group of stereo speakers being unidirectionally aligned; and a third group of stereo speakers positioned between said second sound panel and said base member, said third group of stereo speakers being divergently aligned with respect to one another; said first and third groups of stereo speakers being sealingly mounted in airtight triangularly shaped sound chamber means each packed with acoustical fiber glass and said second group of stereo speakers sealingly mounted in a rectangularly shaped airtight sound chamber means packed with acoustical fiber glass; said first and third groups of stereo speakers each including at least a first pair of parallelly aligned speakers which are orthogonally aligned with at least a second pair of parallelly aligned speakers; said first and second pairs of aligned speakers being positioned outwardly from said triangularly shaped sound chamber means and having vertically positioned sound insulating panels respectively disposed between said top member and said first sound panel and between said second sound panel and said base member; said second group of speakers including at least four unidirectionally aligned speakers, said second group of speakers being divergently aligned with respect to said first and third groups of speakers.
Claim 10
Dependent Claim 326 words
A stereo speaker support means in a cabinet comprising: a base member, said base member comprising a sound insulating horizontal panel; a top member, said top member comprising a horizontal sound panel; a back wall member, said back wall member serving to connect said base member with said top member; a first sound panel horizontally aligned with and positioned between said top member and said base member; a second sound panel horizontally aligned with and positioned between said top member and said base member; a first group of stereo speakers positioned between said top member and said first sound panel, said first group of stereo speakers being divergently aligned with respect to one another; a second group of stereo speakers positioned between said first sound panel and said second sound panel, said second group of stereo speakers being unidirectionally aligned; and a third group of stereo speakers positioned between said second sound panel and said base member, said third group of stereo speakers being divergently aligned with respect to one another; said first and third groups of stereo speakers being sealingly mounted in airtight triangularly shaped sound chamber means each packed with acoustical fiber glass and said second group of stereo speakers sealingly mounted in a rectangularly shaped airtight sound chamber means packed with acoustical fiber glass; said first and third groups of stereo speakers each including at least a first pair of parallelly aligned speakers which are orthogonally aligned with at least a second pair of parallelly aligned speakers; said first and second pairs of aligned speakers being positioned outwardly from said triangularly shaped sound chamber means and having vertically positioned sound insulating panels respectively disposed between said top member and said first sound panel and between said second sound panel and said base member; said second group of speakers including at least four unidirectionally aligned speakers, said second group of speakers being divergently aligned with respect to said first and third groups of speakers.
