ABSTRACT:
A mechanism for a speaker assembly utilizing a brace for confining a speaker cone in a particular orientation. The brace is provided with at least first and second feet which append therefrom. At least one of the feet is fastened to a permanent magnet associated with the cone to isolate vibrations originating in the permanent magnet. In this regard, a plate is employed in conjunction with an elastomeric member such that the elastomeric member is interposed the foot and the plate. The elastomeric member is held to the plate and the first foot. The elastomeric member is sized to create a bias for movement of the brace only in a shear direction relative to the plate and the first foot. A fastener is also employed to support the first and second feet to the permanent magnet at predetermined distances from the permanent magnet.
