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: 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: 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: A microelectromechanical (MEMS) transducer includes a substrate, a moveable electrode supported by the substrate, and a pair of fixed electrodes supported by the substrate, each fixed electrode of the pair of fixed electrodes being configured as a bias or sense electrode. The pair of fixed electrodes are disposed in a stacked arrangement. An end of the moveable electrode is configured for vibrational movement along the stacked arrangement during excitation of the moveable electrode. The pair of fixed electrodes are laterally spaced apart from the end of the moveable electrode to establish a capacitance indicative of the vibrational movement.
