Abstract
An electronic device includes devices such as a power source, a power amplifier, and a speaker. The electronic device may supply an adaptable output voltage to the power amplifier based on a detected operating state of the speaker. Specifically, by designing a connecting circuit between the power source and the power amplifier, when the power amplifier operates on different circuits, the power source can provide different output voltages for the power amplifier, and then provide an adaptable driving power for the speaker.
