An implantable microphone for use in hearing systems includes a housing having a sidewall, a first membrane coupled to a top portion of the housing and configured to move in response to movement from an auditory ossicle, and a second membrane coupled to the sidewall such that an interior volume of the housing is divided into a first volume and a second volume. The first volume has an opening that permits fluid to flow out from the first volume. The implantable microphone also includes a vibration sensor coupled to the second membrane and configured to measure the movement of the second membrane and to convert the measurement into an electrical signal. The vibration sensor may include a piezoelectric sensor and/or a MEMS sensor.

Implantable microphone for hearing systems

An implantable microphone for use in hearing systems includes a housing having a back wall. The back wall has a recess (e.g., blind hole) configured to be coupled to an auditory ossicle. The implantable microphone also includes a membrane coupled to a top portion of the housing and a vibration sensor adjacent to the membrane. The membrane is configured to move in response to movement from the auditory ossicle, and the vibration sensor is configured to measure the movement of the membrane and to convert the measurement into an electrical signal.

An explosion-proof housing includes at least one lower housing part which is provided with a housing wall defining a housing opening that can be closed by an articulated cover. The articulated cover is mounted by an articulation device to be pivotable between an opened and a closed position. In order to allow both a closely adjacent arrangement of housings and the complete utilization of the housing interior, the articulation device includes a lower articulation part arranged in the housing wall, and an upper articulation part arranged on a lower side of the articulated cover which faces the housing opening in a closed position. The lower articulation part and the upper articulation part are pivotably interconnected.

Housing

The invention relates to an implantable electromechanical converter for receiving oscillations from an ear ossicle and for converting them into an electrical voltage, for use as a microphone for a cochlea implant or an implantable hearing aid, consisting of one or more piezoelectric converter elements () housed in a hermetically sealed hollow body () made of a biocompatible material. The converter is characterized in that the hollow body has a thin shell () which is connected with its interior side to the piezoelectric converter elements and which can be coupled with its exterior side to an ear ossicle, and which is held by a stable edge (), whereby the stable edge can be coupled to a counter-support in the middle ear space.
