摘要:
An implanted microphone is provided that has reduced sensitivity to vibration and attendant acceleration forces. In this regard, the microphone differentiates between the desirable and undesirable components of a transcutaneously received signal. More specifically, the present invention utilizes an output that is indicative of acceleration forces acting on the implanted microphone (e.g., an acceleration signal) to counteract and/or cancel the effects of acceleration induced pressures in an output signal of a microphone diaphragm. This may be done in a variety of ways, including but not limited to, pneumatically, mechanically, electrical analog, or digitally, or combinations thereof. In one arrangement, the generated output may be filtered to match the an acceleration response of the output signal of the microphone diaphragm such that upon removal of the motion signal from the microphone output, the remaining signal is an acoustic signal.
摘要:
A system for reducing the vibration sensitivity of an implantable microphone without an equal or greater reduction in sound sensitivity. The system reduces non-ambient vibrations by placing at least one compliant member into the path of transmission for tissue-borne vibration, but not into the path for ambient sound-induced vibration. More particularly, a compliant member is interposed along the path between a source of non-ambient vibration and an implanted microphone. In one aspect, a compliant base member is disposed between an implanted microphone and an implant wearer's skull. In another aspect, a microphone is compliantly suspended relative to an implant housing using a support membrane. In either aspect, the compliant member (i.e., base member and/or membrane) and the supported member (i.e., housing and/or microphone) define a supported system having a natural or resonant frequency. This natural frequency may be set to a value to advantageously isolate the microphone against transmitted vibration.

The invention is directed to an implanted microphone having reduced sensitivity to vibration. In this regard, the microphone differentiates between the desirable and undesirable vibration by utilizing at least one motion sensor to produce a motion signal when an implanted microphone is in motion. This motion signal is used to yield a microphone output signal that is less vibration sensitive. In a first arrangement, the motion signal may be processed with an output of the implantable microphone transducer to provide an audio signal that is less vibration-sensitive than the microphone output alone. In another arrangement, the motion signal may be utilized to actuate at least one actuator. Such an actuator may be capable of applying a force to move the implantable microphone or an implant capsule so as to reduce movement of a microphone diaphragm relative to the skin of a patient which covers the microphone diaphragm.
摘要:
An implantable microphone for use with an implantable hearing instrument that has a reduced vibration sensitivity in comparison with its acoustic sensitivity. The microphone utilizes a plurality of small diaphragms as opposed to a single large diaphragm in order to reduce vibration sensitivity caused by mass loading of the diaphragms by overlying skin and tissue. The acoustic outputs of the plurality of small diaphragms are summed (e.g., acoustically or electronically), which allows the microphone to maintain adequate acoustic sensitivity for hearing augmentation purposes while having a reduced vibration sensitivity. In one aspect, the plurality of diaphragms is formed from a single membrane and a multi-apertured support structure in contact with the membrane. Each aperture in combination with the membrane defines a single diaphragm.
