Integrated beamforming microphone array and ceiling or wall tile
View Patent ↗This disclosure describes a beamforming microphone array integrated into a wall or ceiling tile as a single unit where the beamforming microphone array picks up audio input signals. The beamforming microphone array includes a plurality of microphones that picks up audio input signals. In addition, the wall or ceiling tile includes an outer surface on the front side of the tile where the outer surface is acoustically transparent. The beamforming microphone array is coupled to the tile as a single unit and is integrated into the back side of the tile. Additionally the beamforming microphone array picks up the audio input signals through the outer surface of the tile.

wherein said beamforming microphone array is coupled to the back side of said ceiling tile and all or part of said beamforming microphone array is in the drop space of the drop ceiling.
2. The claim according to claim 1 , wherein said plurality of microphones are positioned at predetermined locations on or in said ceiling tile.
3. The claim according to claim 1 , wherein said ceiling tile is configured to receive each of said plurality of microphones within one or more contours, corrugations, or depressions of said tile.
4. The claim according to claim 1 , wherein said ceiling tile comprises acoustic or vibration damping material.
5. The claim according to claim 1 , wherein said outer surface comprises a grille.
6. The claim according to claim 1 , wherein said outer surface is coplanar with said ceiling tile.
7. The claim according to claim 1 , wherein said outer surface extends below the plane of said ceiling tile.
8. A method of using a ceiling tile beamforming microphone array that integrates a ceiling tile with a beamforming microphone array into a single unit where the ceiling tile is used in a drop ceiling mounting configuration, comprising:
