Abstract
An electronic device may be provided with electrical components such as a power supply that produce heat. Speakers and other components may be controlled using control circuitry within the electronic device. The electronic device may play audio signals through the speakers. Audio data may be received from external equipment or may be maintained locally within the device. A speaker such as a subwoofer may be mounted in a device housing above the power supply so that airflow from the speaker cools the power supply. To enhance cooling, the control circuitry may supply inaudible signals to the speaker that enhance airflow produced by the speaker. The inaudible signals may be supplied in response to detecting current heat-producing audio playback conditions, to predicting future heat-producing conditions, or real-time temperature measurements.
