US 2015/0085441 A1 · Speaker Cooling

Abstract

Embodiments are provided for cooling one or more components of a playback device using speaker vibrations that result from inaudible audio. Movement of air molecules arising from the speaker vibrations may disperse heat away from the one or more components of a playback device. The playback device may include a thermal sensor to determine the temperature on or around one or more components. If the playback device is no longer playing audible audio and temperature on or around one or more components rises above a first predetermined threshold, the playback device may play inaudible audio. Playback of inaudible audio may result in movement of air molecules and the dispersion of heat away from the one or more components. Playback of the inaudible audio may stop if the playback device begins playing audible audio or if the temperature on or around one or more components drops below a second predetermined threshold.

Claims21

Dependent claims

A method for dispersing heat inside a playback device, the method comprising:

determining, based on a detection by a thermal sensor, a temperature on or around one or more components that are located within an enclosure of a playback device, wherein the playback device comprises at least one speaker configured to play audio content;
determining that the temperature is greater than a predetermined value;
and
responsively causing the at least one speaker to play inaudible audio content, wherein playback of inaudible audio content causes the at least one speaker to vibrate and disperse heat away from the one or more components.
