When the USB Type-C female socket 104 is connected to peripheral devices such as a USB disk, a mouse, and a keyboard, the processing procedure is similar to that of connecting a digital earphone, and is not described herein again. In summary, the interface conversion apparatus provided in this embodiment can be compatible with digital earphones and analog earphones of USB Type-C interfaces.
