Abstract

A seal consists of an annular thermoplastic body having a relatively thinner annular base and a relatively thicker, compressible annular bead. The annular body has a shape that corresponds to a mounting surface of a loudspeaker.

A surface of a rim of a loudspeaker basket is placed in contact with a mold to form a substantially annular cavity, a melted thermoplastic material is injected at low-pressure into the cavity to form a seal adhered to the surface.

Claims

1. A method comprising

placing a surface of a rim of a loudspeaker basket in contact with a mold to form a substantially annular cavity,

low-pressure injecting a melted thermoplastic material into the cavity to form a seal adhered to the surface, and

removing the loudspeaker basket from the mold.

2. The method of claim 1 also comprising

positioning the loudspeaker basket on a mounting surface with the thermoplastic material between the loudspeaker basket and the mounting surface, and

attaching the loudspeaker basket to the mounting surface.

3. The method of claim 2 in which the attaching compresses the thermoplastic material to form a seal between the loudspeaker basket and the mounting surface.
