A recently granted patent (Publication Number: US11950050B1) discloses a ceiling tile microphone system that includes a plurality of microphones arranged as a microphone array for beamforming. The system is integrated into a single ceiling tile with an acoustically transparent outer surface, allowing it to be mounted in a drop ceiling. The microphone array is equipped with features such as beamforming, acoustic echo cancellation, auto mixing, auto voice tracking, Power over Ethernet, configurable pickup patterns, adjustable noise cancellation, and additional non-beamforming microphones for enhanced audio resolution. The system also includes adaptive acoustic processing to automatically adjust the beamforming operation based on room configuration, creating an audio beam over a predetermined frequency range.

Furthermore, the patent details a method for manufacturing and using the ceiling tile microphone system, emphasizing the integration of advanced functionalities like auto voice tracking, Power over Ethernet, adjustable noise cancellation, and adaptive acoustic processing. The system's design ensures that all microphones are housed behind the ceiling tile's outer surface in a common housing, with an ethernet connector for power supply and a USB port for additional connectivity. The method highlights the seamless integration of the microphone array into the ceiling tile, enabling easy installation in drop ceilings while providing high-quality audio capture and processing capabilities for various applications, including conference rooms, classrooms, and other commercial settings.
