11/562576

Inventors:

Daniel John Sheehan - Holliston MA, US

International Classification:

H04R 25/00

US Classification:

381150

Abstract:

A mechanically interlocked acoustic radiator/surround assembly is disclosed wherein an edge of the acoustic radiator includes a protrusion extending from and/or a depression in a surface of the acoustic radiator. An elastomeric material is formed around the protrusion and/or fills the depression forming a radiator/surround interface that is not parallel to the surface of the acoustic radiator.

International Classification:

H04R 9/04

US Classification:

381398

Abstract:

An apparatus includes a suspension element coupling a first rigid element to a second rigid element such that the first rigid element is movable in a reciprocating manner relative to the second rigid element. The suspension element includes radial features, some of which may have radial segments of opposite concavity. The segments with opposite concavity provide added stiffness in the primary axis of vibration and may contribute to a more symmetrical force-deflection relationship.
