Abstract
In bone conduction auditory prostheses, a suspension of the electronic components relative to the vibrating mass is beneficial for a number of reasons. The suspension systems depicted also function as a seal, so as to prevent infiltration of direct, water, or other contaminants into the housing. The present technology utilizes a combination suspension and sealing system that seals the housing of an auditory prosthesis while still providing sufficient suspension functionality.
Claims20
An apparatus comprising:
- a rigid housing comprising an interface surface defining an opening through a wall of the rigid housing;
- a vibration transmission element extending at least partially through the opening, wherein the vibration transmission element comprises an outer surface facing the interface surface;
- and
- an elastic element disposed within the opening between the interface surface and the outer surface.

An apparatus comprising:
- a rigid housing comprising a pitched interface surface defining an opening through a wall of the rigid housing, wherein the opening comprises a maximum diameter proximate an outer surface of the wall a minimum diameter proximate an inner surface of the wall;
- and
- a vibration transmission element extending at least partially through the opening, wherein the vibration transmission element comprises:
- a stimulation surface;
- and
- an outer surface facing the interface surface, wherein the diameter of the stimulation surface is greater than the minimum opening diameter;
- and
- an elastic element disposed between the interface surface and the outer surface.
5 more elements
A bone conduction device comprising:
- a rigid housing defining an opening;
- a vibration transmission element protruding through the opening;
- and
- a resilient material disposed around the vibration transmission element that seals the opening and deforms elastically to facilitate stimulation of a recipient via reciprocating movement of the vibration transmission element relative to the housing without deflection of the housing.
