Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
163 words
A speaker supporting device comprising an axially extending annular elastic body having a radially inner peripheral surface and a radially outer peripheral surface, said elastic body having a first open end and a second open end spaced axially apart from said first open end and said open ends each forming an opening therein extending transversely of the axial direction of said elastic body, a baffle plate extending transversely of the axial direction of said elastic body and disposed in tightly fitting contact with said elastic body at the first end thereof, said baffle plate having an opening therethrough aligned with the opening formed by said first open end, and a casing chassis having a portion thereof extending transversely of the axial direction of said elastic body and located in tightly fitting engagement with said second open end of said elastic body, said portion of said casing chassis having an aperture therethrough aligned with the opening in said second end of said elastic body.
Claim 2
Dependent Claim
163 words
A speaker supporting device comprising an axially extending annular elastic body having a radially inner peripheral surface and a radially outer peripheral surface, said elastic body having a first open end and a second open end spaced axially apart from said first open end and said open ends each forming an opening therein extending transversely of the axial direction of said elastic body, a baffle plate extending transversely of the axial direction of said elastic body and disposed in tightly fitting contact with said elastic body at the first end thereof, said baffle plate having an opening therethrough aligned with the opening formed by said first open end, and a casing chassis having a portion thereof extending transversely of the axial direction of said elastic body and located in tightly fitting engagement with said second open end of said elastic body, said portion of said casing chassis having an aperture therethrough aligned with the opening in said second end of said elastic body.
Claim 3
Dependent Claim
46 words
A speaker supporting device, as set forth in claim 1, including an annular groove formed in the inner peripheral surface of said elastic body for receiving an outwardly projecting flange on the circumferential peripheral surface of a speaker with the flange fitted into said annular groove.
Claim 4
Dependent Claim
102 words
A speaker supporting device, as set forth in claim 1, wherein a plurality of increased thickness portions project outwardly from the outer peripheral surface of said elastic body and said increased thickness portions are spaced angularly apart about said elastic body, each of said increased thickness portions having a groove therein in the surface thereof in the plane of the second end of said elastic body, and a plurality of projections on said chassis corresponding to the number of said increased thickness portions and each said projection arranged to fit into a different one of the grooves in said increased thickness portion.
Claim 5
Dependent Claim
62 words
A speaker supporting device, as set forth in claim 3, including a plurality of fittings secured to said casing chassis corresponding to the number of said projections thereon and each said fitting located adjacent a different one of said projections, said fitting shaped to interengage the outer peripheral surface of said elastic body for securing said elastic body to said casing chassis.
