More Information
Summary:An external audio device includes a USB (Universal Serial Bus) plug, an audio socket, a USB communication circuit, an audio socket detection circuit, a first power circuit, a second power circuit, and a control circuit. The USB communication circuit establishes a connection with a computer device coupled to the USB plug according to the communication protocol of USB. The audio socket detection circuit detects a plug-in state of the audio socket. The first power circuit generates a second power to the USB communication circuit according to a first power received from the USB plug. The second power circuit generates a third power to the audio socket detection circuit according to the first power. The control circuit enables or disables the first power circuit according to the plug-in state of the audio socket.
