Abstract
A directional microphone array which can be integrated into a case for a portable computing device. A microphone array board connects to a surface of a laptop computer, tablet computer or smart phone, which can be steered in the direction of a target source. An audio processing module (APM) is operably engaged with the array board to receive a first staged beamformed audio input from the array board, and process a second beamformed stage audio output.
Claims13
A microphone array apparatus comprising:
- a housing configured to be selectively coupled to a substantially planar surface of an electronic device such that a perimeter of the housing is configured to partially encompass the substantially planar surface of the electronic device, the housing having an interior surface and an exterior surface and at least one aperture configured to pass acoustic signals there through;
- and,
- a plurality of microphones being coupled to interior surface of the housing to comprise an array surface such that the plurality of microphones is operable to receive acoustic signals passed through the at least one aperture, the plurality of microphones being arranged in a nested circle configuration with fractal-based spacing between the circles and the microphones.
A microphone array apparatus comprising:
- a coupling mechanism configured to be removably attached to a surface of a smart phone or tablet computer by at least partially encompassing a portion of the smart phone or tablet computer;
- an articulating mechanism coupled to the coupling mechanism;
- an array surface coupled to the articulating mechanism such that the array surface may be selectively positioned in the range of about 180 degrees vertically and about 180 degrees horizontally in the direction of a target audio source;
- and,
- a plurality of microphones comprising an array disposed on the array surface.
