Claims12
A cone speaker having a vibratory edge couplable to a frame, the cone speaker comprising:
- a gasket formed in a rectangular sheet with a flat opening of a girth of a prescribed length at a center, the rectangular sheet having two long sides and two short sides;
- and
- a flame-comprising a gasket holding means formed along an edge opening to hold the gasket and a region configured to hold the vibratory edge, the gasket holding means being separate and spaced from the region configured to hold the vibratory edge, wherein
- the gasket is deformable whereby the opening deforms from a first opening configuration to a second opening configuration generally corresponding to the edge opening and attachable along the edge opening of the frame;
- and
- the gasket holding means of the frame holds the gasket and keeps the gasket deformed so that the opening remains in the second opening configuration
- wherein the gasket holding means is an annular groove formed at an edge of the frame, and
- wherein the vibratory edge is held to the frame separately from the gasket.

A cone speaker having a vibratory edge couplable to a frame, the cone speaker comprising:
- a frame having at least one gasket retainer and a region configured to hold the vibratory edge, the gasket retainer defining an outer perimeter and being separate and spaced from the region configured to hold the vibratory edge;
- and
- a gasket formed with an opening having a first inner perimeter, said opening having an undefined configuration wherein said first inner perimeter of the opening is less than the outer perimeter and wherein the gasket is deformable such that said opening is expandable to a have a deformed configuration to define a second perimeter whereby said second perimeter approximates the outer perimeter;
- wherein the at least one gasket retainer comprises an annular groove formed at an edge of the frame, and
- wherein the vibratory edge is held to the frame separately from the gasket.

A cone speaker having a vibratory edge couplable to a frame, the cone speaker comprising:
- a frame having at least one gasket retainer and a region configured to hold the vibratory edge, the gasket retainer defining an outer perimeter and being separate and spaced from the region configured to hold the vibratory edge;
- and
- a gasket formed with an opening having a first inner perimeter, said opening having an undeformed configuration wherein said first inner perimeter of the opening is less than the outer perimeter and wherein the gasket is deformable such that said opening is expandable to a have a deformed configuration to define a second perimeter whereby said second perimeter approximates the outer perimeter;
- wherein the at least one gasket retainer comprises a plurality of projections formed at an edge of the frame, the plurality of projections separating the gasket retainer from the region configured to hold the vibratory edge, and
- wherein the vibratory edge is held to the frame separately from the gasket.
