Abstract:
The present invention relates to a stereo automatic conversion audio output device comprising: a first input unit and a second input unit which are connected to a portable terminal and receive audio input signals or operation power transmitted via the portable terminal; a first output unit and a second output unit which output the audio input signals received by the first input unit and the second input unit; a function unit which receives the operation power from the portable terminal via the first input unit or the second input unit and performs a unique function; a first switching unit for interrupting a path through which the operation power is supplied from the first input unit to the function unit; a second switching unit for interrupting a path through which the operation power is supplied from the second input unit to the function unit; and a third switching unit for interrupting a path which electrically connects the first input unit and the second input unit. Accordingly, even if one signal line is used as a power supply line in order to supply the operation power to the function unit of the stereo automatic conversion audio output device, the stereo automatic conversion audio output device receives audio input signals from the other signal line, and thus can receive stereo type audio.
