ABSTRACT:
An implanted microphone is provided that has reduced sensitivity to vibration and attendant acceleration forces to differentiate between desirable and undesirable components of a transcutaneously received signal. More specifically, the microphone utilizes an output that is indicative of acceleration forces acting on the implanted microphone to counteract and/or cancel the effects of acceleration-induced pressures in an output signal of a microphone diaphragm. In one arrangement, a microphone having two diaphragms pneumatically cancels acceleration pressures. In this arrangement, a first diaphragm receives and generates a response to commingled acoustic and acceleration forces and a second diaphragm is substantially isolated from the acoustic forces. That is, the second diaphragm generates a response to acceleration forces. The displacements of the first and second diaphragms are pneumatically combined. The result of such pneumatic combination is that the acoustic component of the first diaphragm is enhanced in a resulting output signal.
