Audio voice coil adaptor ring
First Claim
1. A loudspeaker adaptor ring for use with loudspeakers having a lower suspension a cone diaphragm, cone volume and voice coil former for supporting a voice coil, said adaptor ring comprising:
- a sleeve formed with a wall having a first end, a second end, an inner surface defining a hollow interior and an outer surface spaced from said inner surface, said hollow interior being adapted to receive the voice coil former said wall of said sleeve being formed with at least one passage located in between said inner surface and said outer surface thereof for venting air;
a ledge extending outwardly from said outer surface of said sleeve, said ledge defining a planar surface adapted to support at least one of the lower suspension and cone; and
means for securing said sleeve to the voice coil former, said securing means being partially defined by said sleeve.

Abstract
A voice coil adaptor ring and loudspeaker system of the moving coil type including a cone diaphragm supported by a frame, a voice coil former for supporting a voice coil, and a lower suspension for securing and centering the voice coil former in a magnetic gap while it is displaced by a magnetic circuit. The voice coil adaptor ring is mounted over the voice coil former and comprises a substantially cylindrical sleeve having at least one ledge extending outward from said sleeve for supporting the cone and lower suspension and a plurality of venting passages in fluid communication with a cone volume defined by the cone for venting hot air from the cone volume.
