ABSTRACT:
Two stage implantable microphone devices suitable for use in hearing systems are provided. An implantable microphone device may include a housing including a diaphragm with the housing and diaphragm enclosing a chamber; a microphone coupled to the housing; and a vent connecting the microphone to the chamber. Vibrations of the diaphragm are transmitted through the chamber as a first stage and through the vent as a second stage to the microphone. The relative dimensions of the chamber and vent may be utilized to tune the frequency response and sensitivity of the device.
