Ceiling tile microphone
5 Apr 22
This disclosure describes a ceiling tile microphone that includes: a plurality of microphones coupled together as a microphone array used for beamforming, the plurality of microphones are positioned at predetermined locations; a single ceiling tile with an outer surface on the front side of the ceiling tile where the outer surface is acoustically transparent, the microphone array combines with the ceiling tile as a single unit, the ceiling tile being mountable in a drop ceiling in place of a ceiling tile included in the drop ceiling; where the ceiling tile microphone further includes beamforming, acoustic echo cancellation, and auto voice tracking; where the ceiling tile microphone is used in a drop ceiling mounting configuration; where the microphone array couples to the back side of the ceiling tile and all or part of the ceiling tile microphone is in the drop space of the drop ceiling.

Utility
Band-limited beamforming microphone array with acoustic echo cancellation
1 Feb 22
This disclosure describes an apparatus and method of an embodiment of an invention that is a band-limited beamforming microphone array with acoustic echo cancellation that includes: a plurality of first microphones configured as a beamforming microphone array to resolve first audio input signals within a first frequency range, the beamforming microphone array includes acoustic echo cancellation; one or more additional microphone(s) configured to resolve second audio input signals within a restricted second frequency range such that the additional microphone(s) are coupled to the beamforming microphone array; augmented beamforming that processes audio signals from the beamforming microphone array and the additional microphone(s).
