Acoustic receiver having improved mechanical suspension
First Claim
1. A miniature receiver, comprising:
- electro-acoustic components for converting an input audio signal to an output acoustic signal;
a housing for containing at least a portion of said electro-acoustic components, said housing including a port for broadcasting said output acoustic signal, said housing including an end surface through which an electrical connector receives said input audio signal, said end surface being generally opposite of said port; and
a suspension system coupled to said housing for dampening vibrations of said housing, said suspension system including exactly three resilient contact structures configured to maintain direct contact with external structures surrounding said receiver during operation that causes said vibrations, one of said exactly three resilient contact structures being at said end surface and two of said exactly three resilient contact structures being away from said end surface.

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.

7. A receiver, comprising:
-
electro-acoustic components for converting an input audio signal to an output acoustic signal; a housing for containing at least a portion of said electro-acoustic components, said housing including a port for broadcasting said output acoustic signal, said housing having a plurality of surfaces, adjacent ones of said plurality of surfaces meeting at a corner; and a suspension system coupled to said housing for dampening vibrations of said housing, said suspension system including three resilient contact structures having a region of reduced cross-section and configured to maintain direct contact with external structures surrounding said receiver during operation that causes said vibrations, at least one of said three resilient contact structures being positioned along said surfaces away from said corners, said three resilient structures being located away from said port so as to avoid being directly exposed to said output acoustic signal as said output acoustic signal exits said port. - View Dependent Claims (8, 9, 10, 11)
