Abstract
A portable electronic device includes a built-in speaker, an interface configured to connect to an external audio device to output sound, a switch, and a main microchip. The main microchip detects whether the external audio device is connected to the portable electronic device. When the external audio device is connected to the portable electronic device, the main microchip selects the audio device to output sound. When the audio device is not connected to the portable electronic device, the main microchip selects the built-in speaker to output the audio signals.
