Abstract:
1. An audio output device comprising: an audio processor configured to receive audio signals from one or more sources, generating a plurality of audio drive signals, and outputting said audio drive signals to a respective plurality of loudspeakers; a sensing module configured to receive first and second signals corresponding to sound sensed by the plurality loudspeakers, the sensing module including a discriminator configured to discriminate between the audio drive signals and the first and second signals from a first noise source and a second noise source, respectively, within a range of the plurality of loudspeakers, wherein the first noise source comprises a first listener and the second noise source comprises a second listener, and the sensing module is further configured to identify the first listener and the second listener; a position computation processor configured to determine a two or three dimensional position of the first noise source and the second noise source relative to the plurality of loudspeakers; and a user profile memory configured to store a first user preference of the first listener and a second user preference of the second listener defining a set of control parameters governing operation of an electronic device for each of the first and second listeners, wherein the sensing module is further configured to adjust a first drive signal of the plurality of audio drive signals for driving a first loudspeaker of the plurality of loudspeakers in accordance with the first user preference of the identified first listener and to simultaneously adjust a second drive signal of the plurality of audio drive signals for driving a second loudspeaker of the plurality of loudspeakers in accordance with the second user preference of the identified second listener.
