Abstract
An audio system sets a signal line path between the medium of an audio device and an external device and uploads a digital audio file from the external device to the audio device according to a user's manipulation of the audio. In addition, a communication system selectively uses USB and UART communications by commonly using a single USB connector and connects a connector of an external device and an audio/USB/UART common connector through a single cable, so that audio/USB or audio/UART signals are selectively outputted through a common audio signal line. Accordingly, the audio system can interface with various kinds of external devices without external modification or additional installation of a dedicated interface in the audio device with a USB connector. In addition, the USB/UART common communication system can commonly use the USB connector without regard to USB and UART connection signals and can selectively output the audio/USB or audio/UART signals through the single cable in the audio device.
