摘要： A microphone includes a microelectromechanical system (MEMS) device, an amplifier, and an attenuation apparatus. The MEMS device converts acoustic energy into electrical signals. The amplifier is coupled to the MEMS device and receives an input signal from the MEMS device and performs amplification on the input signal to produce an output signal. The attenuation apparatus is coupled to the amplifier. Activation of the attenuation apparatus is effective to attenuate the output signal of the amplifier. A self-noise of the amplifier is attenuated and a sensitivity of the microphone is reduced such that a first signal-to-noise ratio is substantially the same as a second signal-to-noise ratio. The first signal-to-noise ratio occurs when the attenuation apparatus is not activated, and the second signal-to-noise ratio occurs when the attenuation apparatus is activated.

摘要： A surface micromachined microphone with a 230 kHz bandwidth. The structure uses a 2.25 μιη thick, 305 μιη radius polysilicon diaphragm suspended above an 11 μιη gap to form a variable parallel-plate capacitance. The backcavity of the microphone consists of the 11 μιη thick air volume immediately behind the moving diaphragm, and also an extended larger cavity with a radius of 504 μιη. The dynamic frequency response of the sensor in response to electrostatic signals is presented using laser Doppler vibrometry, and indicates a system compliance of 0.4 nm/Pa in the flat-band of the response. The sensor is configured for acoustic signal detection using a charge amplifier configuration, and signal to noise ratio measurements and simulations are presented herein. A resolution of 0.80 mPa/√Hz (32 dB SPL in a 1 Hz bin) is achieved in the flat-band portion of the response extending from 10 kHz to 230 kHz.

摘要： A transducer of the preferred embodiment including a transducer and a plurality of adjacent, tapered cantilevered beams. Each of the beams define a beam base, a beam tip, and a beam body disposed between the beam base and the beam tip. The beams are arranged such that each of the beam tips extends toward a common area. Each beam is joined to the substrate along the beam base and is free from the substrate along the beam body. A preferred method of manufacturing a transducer can include: depositing alternating layers of piezoelectric and electrode onto the substrate in block, processing the deposited layers to define cantilever geometry in block, depositing metal traces in block, and releasing the cantilevered beams from the substrate in block.

摘要： Intra-oral tissue conduction microphone apparatus and methods are described for internal, but non-surgically installed microphones located in the oral cavity. An intra-oral tissue conduction microphone may be attached, adhered or integrated with a removable dental appliance which is positioned against the inside surfaces of the cheek, palate or gingiva. The sensor serves as a component in a non-observable hearing, body sound monitoring or communications device that can operate in environments incompatible with most existing devices. Generally, a piezoelectric film serves as the sensor that is well matched to tissue and which directly converts to an electrical signal by the piezoelectric effect signals which are received through the oral mucosa, gingiva or palate.

摘要： Acoustic transducer means are provided. A monolithic semiconductor layer defines a plate, a pair of oppositely disposed torsional hinges, a flexible extension and at least a portion of a support structure. Acoustic pressure communicated to the plate results in tensile strain of the flexible extension. The flexible extension provides a varying electrical characteristic responsive to the tensile strain. An electric signal corresponding to the acoustic pressure can be derived from the varying electrical characteristic of the flexible extension.

摘要： A piezoelectric MEMS microphone comprising a multi-layer sensor that includes at least one piezoelectric layer between two electrode layers, with the sensor being dimensioned such that it provides a near maximized ratio of output energy to sensor area, as determined by an optimization parameter that accounts for input pressure, bandwidth, and characteristics of the piezoelectric and electrode materials.
