Abstract

Various aspects include a speaker including: an acoustic transducer for providing an audio output; a set of microphones for detecting a user voice command; and a controller coupled with the acoustic transducer and the set of microphones, wherein the controller is configured to: in response to detecting a power down command, switch the set of microphones from an active listening mode to a standby mode for a parking period, in response to detecting a power up command during the parking period, switch the set of microphones from the standby mode to the active listening mode after a first time period, and in response to detecting the power up command after expiration of the parking period switch the set of microphones from the standby mode to the active listening mode after a second time period that is greater than the first time period.

Dependent claims

A speaker, comprising:

an acoustic transducer for providing an audio output;
a set of microphones for detecting a user voice command;
and
a controller coupled with the acoustic transducer and the set of microphones, wherein the controller is configured to:
in response to detecting a power down command, switch the set of microphones from an active listening mode to a standby mode for a parking period,
in response to detecting a power up command during the parking period, switch the set of microphones from the standby mode to the active listening mode after a first time period, and
in response to detecting the power up command after expiration of the parking period, switch the set of microphones from the standby mode to the active listening mode after a second time period that is greater than the first time period.

4 more elements

A non-transitory machine-readable medium comprising a computer program product, which when executed by a processor, causes the processor to control a speaker having an acoustic transducer for providing an audio output, and a set of microphones for detecting a user voice command, wherein controlling the speaker comprises:

in response to detecting a power down command for the speaker, switching the set of microphones from an active listening mode to a standby mode for a parking period,
in response to detecting a power up command during the parking period, switching the set of microphones from the standby mode to the active listening mode after a first time period, and
in response to detecting the power up command after expiration of the parking period, switch the set of microphones from the standby mode to the active listening mode after a second time period that is greater than the first time period.
