Modular hearing device receiver suspension
First Claim
1. A receiver suspension for isolating a hearing device receiver within a hearing device shell, comprising:
- a housing having an inside surface that defines a chamber, an open proximal end, and a distal end;
a cover adapted to engage with the proximal end of the housing; and
an isolation membrane, the isolation membrane at least partially surrounding the hearing device receiver such that, upon insertion of the hearing device receiver into the housing, the isolation membrane suspends the receiver within the housing chamber and prevents contact between the receiver and the housing inside surface, wherein the isolation membrane has a first side, a second side, an opening through its center that is sized to stretch over substantially the entire receiver, and at least one pleat lying parallel with the opening, said pleat folding away from the opening when the receiver is inserted through the opening.

Abstract
A receiver suspension for isolating a hearing device receiver within a hearing device comprises a housing that defines a chamber. The housing is adapted to be inserted into a hearing device shell. The receiver suspension also comprises a cover that is adapted to engage with a proximal end of the housing. An isolation membrane at least partially surrounds the hearing device receiver such that, upon inserting the hearing device receiver into the housing, the isolation membrane suspends the receiver within the housing chamber, thus preventing the receiver from contacting the inside surface of the housing. Preferably, the isolation membrane is formed from a stretched polymer material such as polyurethane or silicone and forms a series of pleats when engaged with the receiver. Alternately, the receiver suspension includes an isolation spring having two grasping members interconnected with a flexure member.
