    • An electret microphone having reduced noise due to reduced leakage current is provided. The microphone includes a flexible diaphragm, and sensor member disposed in opposing, spaced relation to the diaphragm and comprising a semi-conductor channel. At least one electret surface, comprised of a dielectric material having a permanently-embedded static electric charge, is disposed on one of the diaphragm and the sensor member. In turn, the semi-conductor channel of the sensor member has an electrical conductivity dependent upon relative movement of the diaphragm and support member responsive to acoustic signals incident upon the diaphragm, wherein the channel provides an output signal indicative of the acoustic signals. The electret surface may be disposed on the diaphragm. Alternatively, the electret surface may be disposed on the sensor member in spaced, face-to-face relation to an electrically conductive surface located on the diaphragm.

    • A hearing aid and method for stimulating the tympanic membrane of a patient via an input of acoustic signals into the middle ear cavity. The hearing aid includes an acoustic signal receiver, a signal processor, and an implantable transducer. In one aspect of the invention, the impedance of the implantable transducer is matched to a characteristic frequency range of the human tympanic membrane to acoustically couple the transducer with the tympanic membrane. In another aspect of the invention, the impedance of the implantable transducer is matched to a measured impedance of a patient's tympanic membrane to achieve the acoustic coupling. In either case, the acoustic signal receiver receives acoustic sounds and generates frequency response signals for the signal processor. The signal processor, in turn, processes the frequency response signals to generate transducer drive signals for the implanted transducer. The acoustically coupled transducer receives the drive signals to generate acoustic signals, e.g. acoustic sound, that are introduced into the middle ear cavity of the patient to stimulate the tympanic membrane.

    • 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. Specifically, the motion signal may be scaled to match the motion component of the microphone output such that upon removal of the motion signal from the microphone output, the remaining signal is an acoustic signal.
    • 本发明涉及具有降低的对振动的敏感性的植入式麦克风。 在这方面,麦克风通过利用至少一个运动传感器在植入的麦克风运动时产生运动信号来区分期望的和不期望的振动。 该运动信号用于产生较少振动敏感的麦克风输出信号。 在第一布置中,运动信号可以用可植入麦克风换能器的输出进行处理,以提供比单独的麦克风输出更少的振动敏感的音频信号。 具体地,可以对运动信号进行缩放以匹配麦克风输出的运动分量,使得在从麦克风输出移除运动信号时,剩余信号是声信号。
