    摘要： A liquid-resistant microphone assembly includes a substrate defining a sound-entry region and a microphone transducer coupled with the substrate. The transducer has a sound-responsive region acoustically coupled with the sound-entry opening defined by the substrate. A liquid-resistant port membrane spans across the sound-entry opening defined by the substrate. The membrane is gas-permeable. An adhesive layer is positioned between the substrate and the liquid-resistant port membrane, coupling the liquid-resistant port membrane with the substrate and spacing the liquid-resistant port membrane from the substrate to form a gap between the membrane and the substrate. The adhesive layer defines an aperture having a periphery extending around and positioned outward of the sound-entry region. Modules and electronic devices incorporating such a microphone transducer also are disclosed.

    摘要： A micro-electro-mechanical system (MEMS) transducer including an enclosure defining an interior space and having an acoustic port formed through at least one side of the enclosure. The transducer further including a compliant member positioned within the interior space and acoustically coupled to the acoustic port, the compliant member being configured to vibrate in response to an acoustic input. A back plate is further positioned within the interior space, the back plate being positioned along one side of the compliant member in a fixed position. A filter is positioned between the compliant member and the acoustic port, and the filter includes a plurality of axially oriented pathways and a plurality of laterally oriented pathways which are acoustically interconnected and dimensioned to prevent passage of a particle from the acoustic port to the compliant member.

    摘要： A micro speaker having a capacitive sensor to sense a motion of a speaker diaphragm, is disclosed. More particularly, embodiments of the micro speaker include a conductive surface of a diaphragm facing conductive surfaces of several capacitive plate sections across a gap. The diaphragm may be configured to emit sound forward away from a magnet of the micro speaker, and the capacitive plate sections may be supported on the magnet behind the diaphragm. In an embodiment, the gap provides an available travel for the diaphragm, which may be only a few millimeters. A sensing circuit may sense capacitances of the conductive surfaces to limit displacement of the diaphragm to within the available travel.

    摘要： A mobile multi-function device that includes a speaker, two or more microphones, and a beamformer processor is described. The beamformer processor uses the microphones to perform beamforming operations. One of the microphones shares a receiver acoustic opening with the speaker while the other microphone uses a separate acoustic opening. The receiver acoustic opening may be an earpiece opening that is held to the ear of a user while conducting a phone call with the device and provides acoustic input and output paths for the microphone and the speaker, respectively.
