Abstract

Disclosed herein are example techniques for acoustic position measurement in an example listening environment. One example includes determining a requirement for position information of a speaker-equipped device within a room in which a media playback system is located, and in response to determining the requirement for position information of the speaker-equipped device, determining a position of the speaker-equipped device relative to a microphone-equipped device of the media playback system based at least in part on a test sound emitted from the speaker-equipped device. After determining the position of the speaker-equipped device relative to the microphone-equipped device, some examples further include configuring one or more audio configuration parameters of the media playback system based on the position of the speaker-equipped device relative to the microphone-equipped device.

Dependent claims

Tangible, non-transitory, computer-readable media having instructions encoded therein, wherein the instructions, when executed by one or more processors, cause a microphone-equipped device to perform a method comprising:

determining a requirement for position information of a speaker-equipped device within a room in which a media playback system is located, wherein determining a requirement for position information of the speaker-equipped device in the media playback system comprises receiving a command that causes the microphone-equipped device to configure a beamforming microphone array of the microphone-equipped device based at least in part on a location of the speaker-equipped device relative to the microphone-equipped device;
in response to determining the requirement for position information of the speaker-equipped device, determining a position of the speaker-equipped device relative to the microphone-equipped device based at least in part on a test sound emitted from the speaker-equipped device;
and
after determining the position of the speaker-equipped device relative to the microphone-equipped device, configuring one or more audio configuration parameters of the media playback system based at least in part on the position of the speaker-equipped device relative to the microphone-equipped device, wherein configuring one or more audio configuration parameters of the media playback system based on the position of the speaker-equipped device relative to the microphone-equipped device comprises configuring the beamforming microphone array of the microphone-equipped device to attenuate sound originating from the position of the speaker-equipped device.

A microphone-equipped device comprising:

a network interface;
one or more processors;
and
tangible, non-transitory computer-readable media having instructions encoded therein, wherein the instructions, when executed by the one or more processors, cause the microphone-equipped device to perform functions comprising:
determining a requirement for position information of a speaker-equipped device within a room in which a media playback system is located, wherein determining a requirement for position information of the speaker-equipped device in the media playback system comprises receiving a command to configure a beamforming microphone array of the microphone-equipped device based at least in part on a location of the speaker-equipped device relative to the microphone-equipped device;
in response to determining the requirement for position information of the speaker-equipped device, determining a position of the speaker-equipped device relative to the microphone-equipped device of the media playback system based at least in part on a test sound emitted from the speaker-equipped device;
and
after determining the position of the speaker-equipped device relative to the microphone-equipped device, configuring one or more audio configuration parameters of the media playback system based on the position of the speaker-equipped device relative to the microphone-equipped device, wherein configuring one or more audio configuration parameters of the media playback system based on the position of the speaker-equipped device relative to the microphone-equipped device comprises configuring the beamforming microphone array of the microphone-equipped device to attenuate sound originating from the position of the speaker-equipped device.

5 more elements

A method comprising:

determining a requirement for position information of a speaker-equipped device within a room in which a media playback system is located;
in response to determining the requirement for position information of the speaker-equipped device, determining a position of the speaker-equipped device relative to one or more microphone-equipped devices of the media playback system based at least in part on a test sound emitted from the speaker-equipped device, wherein determining a requirement for position information of the speaker-equipped device in the media playback system comprises receiving a command to configure a beamforming microphone array of the microphone-equipped device based at least in part on a location of the speaker-equipped device relative to at least one of the one or more microphone-equipped devices;
and
after determining the position of the speaker-equipped device relative to the one or more microphone-equipped devices, configuring one or more audio configuration parameters of the media playback system based on the position of the speaker-equipped device relative to the one or more microphone-equipped devices, wherein configuring one or more audio configuration parameters of the media playback system based on the position of the speaker-equipped device relative to the one or more microphone-equipped devices comprises configuring the beamforming microphone array of the microphone-equipped device to attenuate sound originating from the position of the speaker-equipped device.
