US 9,872,119 B2 · Audio settings of multiple speakers in a playback device

Abstract

Techniques described herein may involve dynamically adjusting the equalization of multiple speakers in a playback device. An example implementation involves a playback device emitting, via a first speaker, a first audio signal and emitting, via a second speaker, a second audio signal. The playback device may detect, via a microphone, an audio signal representing (i) at least a portion of the first audio signal and (ii) at least a portion of the second audio signal. The implementation may further involve the playback device determining one or more reflection characteristics based on the detected audio signal. The example implementation may also involve identifying a first audio setting and a second audio setting based on one or more reflection characteristics and applying (i) the first audio setting to playback of media content via the first speaker and (ii) the second audio setting to playback of media content via the second speaker.

Dependent claims

A playback device of a media playback system, the media playback system consisting of the playback device, the playback device comprising:

a first speaker that is contained within a housing of the playback device;
a second speaker that is contained within the housing of the playback device;
a microphone that is contained within the housing of the playback device;
a processor;
and
memory having stored thereon instructions executable by the processor to cause the playback device to perform functions comprising:
emitting, via the first speaker, a first audio signal;
detecting, via the microphone, an audio signal representing at least a portion of the first audio signal and at least a portion of a reverberation of the first audio signal;
determining one or more reflection characteristics based on the detected audio signal;
identifying a first audio setting and a second audio setting based on the one or more reflection characteristics;
and
applying (i) the first audio setting to playback of media content via the first speaker and (ii) the second audio setting to playback of media content via the second speaker.

9 more elements

A method for a playback device of a media playback system, the media playback system consisting of the playback device, the method comprising:

emitting, via a first speaker contained within a housing of a playback device, a first audio signal;
detecting, via a microphone contained within the housing of the playback device, an audio signal representing at least a portion of the first audio signal and at least a portion of a reverberation of the first audio signal;
determining one or more reflection characteristics based on the detected audio signal;
identifying a first audio setting and a second audio setting based on the one or more reflection characteristics;
and
applying (i) the first audio setting to playback of media content via the first speaker and (ii) the second audio setting to playback of media content via a second speaker contained within the housing of the playback device.

3 more elements

A tangible, non-transitory computer-readable medium having stored thereon instructions executable by a processor to cause a playback device of a media playback system, the media playback system consisting of the playback device, to perform functions comprising:

emitting, via a first speaker contained within a housing of the playback device, a first audio signal;
emitting, via a second speaker contained within the housing of the playback device, a second audio signal;
detecting, via a microphone contained within the housing of the playback device, an audio signal representing (i) at least a portion of the first audio signal and (ii) at least a portion of the second audio signal;
determining one or more reflection characteristics based on the detected audio signal;
identifying a first audio setting and a second audio setting based on the one or more reflection characteristics;
and
applying (i) the first audio setting to playback of media content via the first speaker and (ii) the second audio setting to playback of media content via the second speaker.
