Abstract
An audio device includes a digital-to-analog converter, an amplifier, a speaker, a power management unit and a temperature sensor. The digital-to-analog converter is configured to convert a digital audio signal into an analog audio signal. The amplifier is coupled to the digital-to-analog converter and configured to amplify the analog audio signal and generate an amplified analog audio signal. The speaker is coupled to the amplifier and configured to broadcast the amplified analog audio signal. The power management unit is configured to provide the amplifier with a first working voltage and provide the digital-to-analog converter with a second working voltage. The temperature sensor is coupled to the speaker and configured to generate a temperature detection signal according to a temperature of the speaker. Wherein, the power management unit adjusts at least one of the first working voltage and the second working voltage according to the temperature detection signal.
