Abstract
To avoid damage from overheating, playback device operation can be modulated based on input from temperature sensors. An example method includes obtaining, via one or more temperature sensors carried by the playback device, temperature data. Based on the temperature data, a first temperature parameter is detected. In response to detecting the first temperature parameter, a gain of audio playback is decreased by a first amount. After decreasing the gain of audio playback by the first amount, a second temperature parameter is detected. In response to detecting the second temperature parameter, the gain of audio playback is decreased by a second amount different than the first amount.
Claims20
A playback device comprising:
- a plurality of temperature sensors;
- at least one audio transducer;
- one or more processors;
- and
- data storage having instructions thereon that, when executed by the one or more processors, cause the playback device to perform operations comprising:
- obtaining sensor data from each of the plurality temperature sensors, the sensor data indicating an increase in temperature;
- for each temperature sensor, determining an amount of gain reduction to be applied to audio playback based at least in part on the sensor data;
- and
- decreasing a gain of audio playback by a first amount, wherein the first amount comprises the largest gain reduction from among the gain reductions determined for each of the temperature sensors.
A method of thermal control of a playback device, the method comprising:
- obtaining sensor data from each of a plurality of temperature sensors carried by the playback device, the sensor data indicating an increase in temperature;
- for each temperature sensor, determining an amount of gain reduction to be applied to audio playback based at least in part on the sensor data;
- and
- decreasing a gain of audio playback by a first amount, wherein the first amount comprises the largest gain reduction from among the gain reductions determined for each of the temperature sensors.
One or more tangible, non-transitory computer-readable media storing instructions that, when executed by one or more processors of a playback device, cause the playback device to perform operations comprising:
- obtaining sensor data from each of a plurality of temperature sensors carried by the playback device, the sensor data indicating an increase in temperature;
- for each temperature sensor, determining an amount of gain reduction to be applied to audio playback based at least in part on the sensor data;
- and
- decreasing a gain of audio playback by a first amount, wherein the first amount comprises the largest gain reduction from among the gain reductions determined for each of the temperature sensors.
