System and method for omnidirectional adaptive loudspeaker

A method for providing an adaptive loudspeaker assembly, the method comprising:

• transmitting, a loudspeaker array, an audio output signal in an omnidirectional sound mode in a room having a plurality of walls;
• capturing, via a microphone array, the audio output signal in the room;
• determining with at least one controller that at least one first wall of the plurality of walls is closest to the loudspeaker array based on the captured audio output signal;
• and
• changing a sound mode of the loudspeaker array from transmitting the audio output signal in the omnidirectional mode into a beamforming sound mode to transmit the audio output signal away from the at least one first wall of the plurality walls;
• receiving by the at least one controller, a captured audio signal including background noise from the microphone array and a reference signal indicative of an equalized audio input prior to the loudspeaker array transmitting the audio output signal, wherein the background noise and the reference signal are uncorrelated;
• and
• executing an adaptive algorithm by the at least one controller to reduce the background noise on the captured audio signal prior to determining that the at least one first wall of the plurality of walls is closest to the loudspeaker array.

A system for providing an adaptive loudspeaker assembly, the system comprising:

• a circular loudspeaker array for transmitting an audio output signal in an omnidirectional sound mode in a room having a plurality of walls;
• a circular microphone array being coupled to the circular loudspeaker array to capture the audio output signal in the room;
• and
• at least one controller programmed to:
• receive the captured audio output signal indicating a plurality of sound reflections from the plurality of walls;
• determine that at least one first wall of the plurality of walls is closest to the circular loudspeaker array based on a first sound reflection from the at least one first wall being the strongest reflection out of the plurality of sound reflections;
• and
• change a sound mode of the circular loudspeaker array from transmitting the audio output signal in the omnidirectional mode into a beamforming sound mode to transmit the audio output signal away from the at least one first wall of the plurality walls,
• wherein the at least one controller is further programmed to:
• receive a captured audio signal including background noise from the microphone array and a reference signal indicative of an equalized audio input prior to the circular loudspeaker array transmitting the audio output signal;
• and
• wherein the background noise and the reference signal are uncorrelated and the at least one controller executes an adaptive algorithm to reduce the background noise on the captured audio signal prior to determining that the at least one first wall of the plurality of walls is closest to the loudspeaker array.
