Abstract: An acoustic sensor module includes an acoustic sensor device including a transducer and an enclosure configured to encapsulate and seal the acoustic sensor device within the enclosure. The enclosure includes a first sound port configured to couple a first side of the transducer to an embodiment environment via a first acoustic channel formed in the enclosure. The enclosure also includes a second sound port configured to couple a second side of the transducer to the embodiment environment via a second acoustic channel formed in the enclosure. The enclosure additionally includes a notch formed on a surface of the enclosure. The notch is configured to enable detection of a leakage path, within the enclosure, between the first sound port and the second sound port around an outside of the acoustic sensor device.

Abstract: An acoustic sensor device includes a substrate and a first transducer supported by the substrate, the first transducer configured to generate a first output signal when exposed to a sound wave. The acoustic sensor device also include a second transducer supported by the substrate, the second transducer configured to generate a second output signal when exposed to a sound wave. The first transducer and the second transducer are configured such that the first output signal generated by the first transducer and the second output signal generated by the second transducer are opposite in polarity.

Abstract: A microelectromechanical system (MEMS) transducer includes a substrate and a pair of electrodes supported by the substrate. The pair of electrodes are configured as a bias electrode-sense electrode couple. A moveable electrode of the pair of electrodes is configured for vibrational movement in a first direction during excitation of the moveable electrode. The pair of electrodes are spaced apart from one another by a gap in a second direction perpendicular to the first direction. The moveable electrode includes a cantilevered end, the cantilevered end being warped to exhibit a resting deflection along the first direction.

Abstract: Microphones, microphone systems, and methods for capturing and processing sound are described. The microphones and microphone systems may adaptively change the direction from which sound is captured. The microphones and microphone systems avoid the need to provide arrays of microphones, while providing adaptive beamforming without a time delay between each channel of information, and multi-directional sound capture. A dependency between the frequency response and system size is also avoided.

Abstract: An electrostatic transducer includes a substrate oriented in a plane, a fixed electrode supported by the substrate, and a moveable electrode supported by the substrate, spaced from the fixed electrode in a first direction parallel to the plane, and configured for movement in a second direction transverse to the plane, such that an extent to which the fixed and moveable electrodes overlap changes during the movement. The fixed and moveable electrodes comprise one or more of a plurality of conductive layers, the plurality of conductive layers including at least three layers. The fixed electrode includes a stacked arrangement of two or more spaced apart conductive layers of the plurality of conductive layers.
