Abstract
Systems and methods are described to extract desired audio from an apparatus to be worn on a user's head. An apparatus includes a head wearable device and an array of at least three microphones. The at least three microphones are arranged along a plurality of at least two non-parallel axes. Selection logic is configured to identify a selected axis from the plurality and two microphones from the array that form the selected axis. A beamformer is configured to accept as inputs, signals from the two microphones and to output a main microphone channel and a reference microphone channel.
Claims20
An apparatus to be worn on a user's head, comprising:
- a head wearable device;
- an array of at least three microphones, the at least three microphones are arranged along a plurality of at least two non-parallel axes, wherein a first microphone and a second microphone of the array define a first axis of the plurality of at least two non-parallel axes, wherein the second microphone and a third microphone define a second axis of the plurality of at least two non-parallel axes, and wherein the first microphone and the second microphone are located on an inside surface of a first temple of the head wearable device and the third microphone is located on a bottom surface of the first temple;
- selection logic, the selection logic is configured to identify a selected axis from the plurality and two microphones from the array that form the selected axis;
- and
- a beamformer, the beamformer is configured to accept as inputs, signals from the two microphones and to output a main microphone channel and a reference microphone channel.
