Loudspeaker array protection management
09743201 · 2017-08-22 · ·

A protection management unit is described that detects one or more poor performing transducers in a loudspeaker array. Upon detection of one or more poor performing transducers, the protection management unit adjusts driving signals for neighboring transducers to compensate for the reduced capabilities of the poor performing transducers. By adjusting driving signals to neighboring transducers, the protection management unit ensures that a desired tone and spatial response for sound emitted by the loudspeaker array is maintained despite one or more poor performing transducers. Other embodiments are also described.

PACKAGE WAVEGUIDE FOR ACOUSTIC SENSOR WITH ELECTRONIC DELAY COMPENSATION

A system and method use an array of ultrasonic transducers to emit and receive sound in a phased array fashion by using acoustic waveguides to achieve a desired acoustic radiation and reception pattern. A chip package attached to an acoustic transducer array includes acoustic waveguides coupled to acoustic ports. Each waveguide is coupled between a corresponding acoustic transducer and a corresponding acoustic port. A spacing of a pair of acoustic ports is different than a spacing of a corresponding pair of acoustic transducers.
