Abstract
An electronic device includes a central processing unit, a USB connector, a USB switch, and an audio path selector. The USB switch has a data transmission path and an audio signal transmission path for signal transmission between the central processing unit and the USB connector. The USB switch selects the data transmission path for data transmission according to a first selection signal from the central processing unit, and selects the audio signal transmission path for audio signal transmission according to a second selection signal from the central processing unit. The audio path selector interconnects the central processing unit and the USB switch, and has a first audio path for output of audio signals from the central processing unit to the audio signal transmission path, and a second audio path for output of audio signals from the audio signal transmission path to the central processing unit.
