ABSTRACT:
The present invention is a receiver that includes electronics for converting an input audio signal to an output acoustic signal. The receiver has a housing for containing at least a portion of the electronics. The housing includes a port for broadcasting the output acoustic signal. A suspension system is coupled to the housing for dampening vibrations of the housing. In one preferred embodiment, the suspension system includes three resilient contact structures for contacting a surrounding structure in which the receiver is placed. The contact structures are positioned at specific locations to provide variable dampening levels. In another embodiment, the dampening is provided by a low-viscosity, gel-like material positioned between the housing and the surrounding structure.
