    摘要： A microphone includes a microelectromechanical system (MEMS) circuit and an integrated circuit. The MEMS circuit is configured to convert a voice signal into an electrical signal, and the integrated circuit is coupled to the MEMS circuit and is configured to receive the electrical signal. The integrated circuit and the MEMS circuit receive a clock signal from an external host. The clock signal is effective to cause the MEMS circuit and integrated circuit to operate in full system operation mode during a first time period and in a voice activity mode of operation during a second time period. The voice activity mode has a first power consumption and the full system operation mode has a second power consumption. The first power consumption is less than the second power consumption. The integrated circuit is configured to generate an interrupt upon the detection of voice activity, and send the interrupt to the host.

    摘要： An acoustic apparatus includes a substrate, micro electro mechanical system (MEMS) die, and an integrated circuit. The substrate includes a permanent opening that extends there through. The micro electro mechanical system (MEMS) die is disposed over the permanent opening and the MEMS die includes a pierce-less diaphragm that is moved by sound energy. A first temporary opening extends through the substrate. The integrated circuit is disposed on the substrate and includes a second opening. The first temporary opening and the second opening are generally aligned. A cover that is coupled to the substrate and encloses the MEMS die and the integrated circuit. The cover and the substrate form a back volume, and the diaphragm separates the back volume from a front volume. The first temporary opening is unrestricted at a first point in time to allow gasses present in the back volume to exit through the temporary opening to the exterior and the pierce-less diaphragm prevents the gasses from passing there through. The first temporary opening is later substantially filled and closed at a second point in time, after which the acoustic device becomes operational.

    摘要： An the acoustic apparatus comprising a first MEMS motor that includes a first diaphragm and a first back plate, and a second MEMS motor that includes a second diaphragm and a second back plate. The first motor is biased with a first electrical polarity and a second motor is biased with a second electrical polarity such that the first electrical polarity and the second electrical polarity are opposite. At the first motor, a first signal is created that is representative of received sound energy. At the second motor, a second signal is created that is representative of the received sound energy. A differential output signal that is the representative of the difference between the first signal and the second signal is obtained. In obtaining the differential output signal, common mode noise between the first motor and the second motor is rejected.

    摘要： A Microelectromechanical system (MEMS) assembly includes a substrate, lid, MEMS device, and at least one wall. The substrate has electrical connection pads and the electrical connection pads are coupled to electrical conductors extending through the substrate. The MEMS device is attached to the lid. The at least one wall is coupled to the lid and the substrate and is formed separately from the lid and has an electrical conduit disposed therein. The electrical conduit is electrically coupled to the electrical conductors on the substrate. The electrical conduit and electrical conductors form an electrical path between the MEMS device and the electrical connection pads.
