摘要： An image capture device includes a housing that includes a pattern of apertures and a microphone disposed within the housing and proximate to the apertures. The image capture device includes a membrane assembly. The membrane assembly includes a support disposed between the housing and the microphone and a channel defined in the support that directs sound waves from only one of the apertures in the pattern to the microphone. The membrane assembly further includes a membrane that extends across the channel and separates the one of the apertures and the microphone.

摘要： The present invention provides a microphone assembly having shielding function for a motor vehicle, comprising: a microphone circuit board having a microphone, which is supplied by a differential audio bus such that the ground potential of the microphone is floating; a cover which is located outside the microphone circuit board; a foamy part which is located between the cover and the microphone circuit board; and a shielding film which is suitable for shielding the microphone against electrostatic discharge, wherein the shielding film is located between the cover and the foamy part and covers the outer surface of the foamy part, and wherein the shielding film is electrically conductive and grounded to a vehicle chassis ground potential. In this situation, the shielding film can collect electrostatic charges and guide them to the chassis ground of the vehicle, so that electronic components on the microphone circuit board under the shielding film, especially the microphones having the floating ground, can be shielded from electrostatic discharge (ESD) damage. As a result, the ESD robust performance of the microphone assembly is significantly improved.

摘要： The present disclosure relates to an integrated circuit connectable to a microelectromechanical system (MEMS) transducer. The MEMS transducer is configured to generate a transducer audio signal in response to sound. The integrated circuit comprises a digital scrambling circuit coupled to a data communication interface. The digital scrambling circuit is configured to convert a digital audio stream, representative of the transducer audio signal, into a corresponding scrambled data stream. The integrated circuit additionally comprises a data bus interface coupled to the digital scrambling circuit and configured to output the scrambled data stream.

摘要： A microelectromechanical system (MEMS) microphone includes a cavity to receive an acoustic signal. The acoustic signal causes movement of a diaphragm relative to one or more other surfaces, which in turn results in an electrical signal representative of the received acoustic signal. A light sensor is included within the packaging of the MEMS microphone such that an output of the light sensor is representative of a light signal received with the acoustic signal. The output of the light sensor is used to modify the electrical signal representative of the received acoustic signal in a manner that limits light interference with an acoustical output signal.

摘要： The present disclosure relates to devices and methods for programming one-time programmable fuses of microphone assemblies. One microphone assembly includes a housing, a transducer, a filter circuit, and an integrated circuit. The integrated circuit has a fuse block having a one-time programmable (OTP) fuse configurable in a programming mode of operation during which a voltage applied to the supply voltage contact is increased relative to a voltage applied to a supply voltage contact in a normal mode of operation. The microphone assembly further includes a protection circuit configured to regulate a voltage at the voltage input terminal of the integrated circuit during the programming mode of operation based on a comparison of a voltage at the voltage input terminal with a reference voltage. The voltage on the voltage input terminal of the integrated circuit tracks the reference voltage during the programming mode of operation.
