Abstract
This invention relates to an implantable microphone device. The implantable microphone device typically comprises a housing defining an internal chamber. It typically further comprises a microphone arrangement on the housing, the microphone arrangement having a first cavity, a second cavity, and a membrane separating the first and second cavities such that vibrations entering the first cavity causes the membrane to vibrate, and to transmit vibrations into the second cavity. The implantable microphone device further comprises at least one vent extending between the second cavity of the microphone arrangement and the internal chamber of the housing so as to permit the vibrations to pass from the second cavity of the microphone arrangement into the internal chamber of the housing.
