  • Publication number: 20160363477
    Abstract: Systems and method for providing an audio output with an acoustic intensity analyzer. The acoustic intensity analyzer includes an acoustic intensity array, a controller, and an orientation sensor. The acoustic intensity array is fixed to the acoustic intensity analyzer. The controller is coupled to the acoustic intensity array to produce the audio output using acoustic holography based on an input from the acoustic intensity array. The controller is configured to set an aim of the acoustic holography in a selected direction. The orientation sensor is coupled to the controller and mechanically fixed to the acoustic intensity analyzer such that there is no relative movement between the orientation sensor and the acoustic intensity array. The orientation sensor detects a change in an orientation of the acoustic intensity array and provides an orientation signal to the controller for adjusting the aim of the acoustic holography to maintain the selected direction.

  • Publication number: 20160080871
    Abstract: A microelectromechanical system (MEMS) microphone in one embodiment includes a backplate, a back cavity aligned with the backplate, at least one post extending from the backplate toward the back cavity, a membrane positioned between the backplate and the back cavity and including an inner portion and an outer portion, a gap defined by a planar portion of the inner portion and the backplate, a spring arm defined in the outer portion and supported by the at least one post, a first leak path between the back cavity and the gap defined between the inner portion and the spring arm, a second leak path between the back cavity and the gap defined between the spring arm and the back cavity, and a first leak path constriction configured to restrict leakage through at least one of the first leak path and the second leak path.
