  • Beamforming a digital microphone array on a common platform
    Patent number: 9467778
    Abstract: An interface for an array of digital microphones in an electronic device may include a head-end chip coupled to the digital microphones through a bus. The bus may be shared by each microphone of the array of microphones and be multiplexed to allow transmission of data from the microphones to the head-end chip and transmission of power from the head-end chip to the array of digital microphones. The head-end chip may perform signal processing on receive data from the array of digital microphones to create beamforming arrays. The array of microphones may include microphones with different characteristics to improve performance of the array of microphones.
    Type: Grant
