Playback based on number of listeners
First Claim
1. A playback device comprising:
- one or more speakers;
at least one amplifier configured to drive the one or more speakers;
one or more location sensors comprising a network interface;
one or more processors comprising a digital signal processor; and
a housing carrying the one or more speakers, the at least one amplifier, the one or more location sensors, the one or more processors, and data storage for storing instructions that when executed cause the playback device perform functions comprising;
detecting, at a first time, a first number of listeners in a listening area, wherein detecting the first number of listeners comprises receiving, via the network interface of the one or more location sensors, network packets transmitted from a mobile device associated with a first listener, wherein the detected first number of listeners is one;
determining a first audio characteristic that adjusts a sound field generated by the one or more speakers to create a first sweet spot that includes a location of the first listener relative to the playback device;
processing, via the digital signal processor, an audio signal for playback according to the first audio characteristic;
playing the processed audio signal via the one or more speakers and the at least one amplifier according to the first audio characteristic;
while processing the audio signal for playback according to the first audio characteristic, detecting, at a second time, a second number of listeners in the listening area, wherein detecting the second number of listeners comprises receiving, via the network interface of the one or more location sensors, network packets transmitted from respective mobile devices associated with two or more second listeners, and wherein the detected second number of listeners is greater than one;
determining a second audio characteristic that adjusts the sound field generated by the one or more speakers to create a second sweet spot that includes respective locations of the two or more second listeners;
after determining the second audio characteristic, processing, via the digital signal processor, the audio signal for playback according to the second audio characteristic; and
playing the processed audio signal via the one or more speakers and the at least one amplifier according to the second audio characteristic.

Abstract
Systems, methods, and apparatus to process audio signals based on a number of listeners are disclosed. An example implementation involves a playback device processing, via an audio processing component, an audio signal for playback according to a first audio characteristic. While processing the audio signal for playback according to the first audio characteristic, the playback device detects, via a location component, a number of listeners in a listening area. The playback device determines a second audio characteristic based on the detected number of listeners in the listening area, and after determining the second audio characteristic, processes, via the audio processing component, the audio signal for playback according to the second audio characteristic.
