Abstract
Abstract A loudspeaker assemblage is made up of a group of cylindrical speaker housings, with a speaker mounted in each housing. A respective spacer in the form of a wedge block or angle sleeve is interposed between adjacent housings, so that housing end closures abut respective wedges. A flexible tension member passes through each speaker housing and spacer so that when the tension member is taut, the housings and spacers are clamped to make up a relatively rigid structure having a generally toroidal shape. The tension member is releasable so that the speaker housings can be rotated about a respective axis normal to the speaker axis to selectively orient the speakers. When the tension member is taut, the speakers are retained in the selected orientation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A loudspeaker assemblage comprising: a. a group of speakers, with each speaker having a central axis; b. support means for each said speaker, with each said speaker being fixed to a respective said support means; c. means interconnecting all said support means to form an annular structure having a central axis and providing individual adjustment of said speakers to respective selected positions relative to a respective rotational axis which intersects and is normal to the respective said speaker central axis and also is normal to a radial plane of said annular structure that bisects said respective speaker and contains the speaker central axis, and with each said speaker facing away from a common side of the central plane of said annular structure.
Claim 2
Dependent Claim
122 words
A loudspeaker assemblage comprising: a. a group of speakers, with each speaker having a central axis; b. support means for each said speaker, with each said speaker being fixed to a respective said support means; c. means interconnecting all said support means to form an annular structure having a central axis and providing individual adjustment of said speakers to respective selected positions relative to a respective rotational axis which intersects and is normal to the respective said speaker central axis and also is normal to a radial plane of said annular structure that bisects said respective speaker and contains the speaker central axis, and with each said speaker facing away from a common side of the central plane of said annular structure.
Claim 3
Dependent Claim
51 words
The device of claim 1 wherein said support means for each speaker comprises a housing and said interconnecting means includes a respective spacer disposed between each adjacent pair of speaker housings; each said speaker being fixed relative to its housing and each said housing being rotatably adjustable relative to adjacent spacers.
Claim 4
Dependent Claim
37 words
The device of claim 2 wherein each said housing has a cylindrical shape and each said spacer is a wedge shaped block with an end surface of each housing abuting a side surface of each adjacent spacer.
Claim 5
Dependent Claim
26 words
The device of claim 3 wherein a flexible tension member passes through each said housing and each said spacer to releasably clamp said housings and spacers.
Claim 6
Dependent Claim
33 words
The device of claim 2 wherein each said housing has a cylindrical shape and each said spacer is an angle sleeve having end flanges sized to receive ends of respective adjacent cylindrical housings.
Claim 7
Dependent Claim
18 words
The device of claim 4 wherein the cylindrical portion of each said housing is made of laminated fibreboard.
Claim 8
Dependent Claim
18 words
The device of claim 5 wherein the cylindrical portion of each said housing is made of laminated fibreboard.
Claim 9
Dependent Claim
16 words
The device of claim 6 wherein said housing forms an effectively closed baffle for its speaker.
Claim 10
Dependent Claim
16 words
The device of claim 7 wherein said housing forms an effectively closed baffle for its speaker.
