Abstract
A wireless charging system may include a wireless power receiving device that receives wireless power signals form a wireless power transmitting device. To reduce temperature of the wireless power receiving device during wireless charging operations, an air-circulating component may at least intermittently circulate air within an interior cavity that includes wireless charging components.
Claims20
An electronic device, comprising:
- one or more components forming an interior cavity;
- one or more wireless charging components disposed in the interior cavity;
- a speaker at least partially exposed to the interior cavity and an external environment;
- and
- control circuitry disposed in the interior cavity and configured to, in accordance with detecting a temperature condition, use the speaker to circulate air in the interior cavity.
A method of operating an electronic device that includes one or more components forming an interior cavity, one or more wireless charging components disposed in the interior cavity, and a speaker at least partially exposed to the interior cavity and an external environment, the method comprising:
- in accordance with detecting a temperature condition, using the speaker to circulate air in the interior cavity.
A non-transitory computer-readable storage medium storing one or more programs configured to be executed by one or more processors of an electronic device that includes one or more components forming an interior cavity, one or more wireless charging components disposed in the interior cavity, and a speaker at least partially exposed to the interior cavity and an external environment, the one or more programs including instructions for:
- in accordance with detecting a temperature condition, using the speaker to circulate air in the interior cavity.
