Mobile device for multi-channel sound collection and output using common connector, and driving method thereof

摘要

A mobile device for providing multi-channel sound collection and output using a common connector, and a driving method thereof are provided. A mobile device having a sound compressor and a sound decompressor includes a connector slidably receiving a sound collector plug or a sound output plug, a plug identification unit for, if one of the sound collector plug and the sound output plug is coupled to the connector, identifying if the plug coupled to the connector is the sound collector plug or is the sound output plug, a switching unit for electrically coupling the plug coupled to the connector, to the sound compressor, or electrically coupling the plug coupled to the connector, to the sound decompressor, and a controller for controlling switching of the switching unit according to the identification outcome.

1. A mobile device having a sound compressor and a sound decompressor, comprising:
a connector for receiving a sound collector plug or a sound output plug; a plug identification unit for identifying whether the plug electrically coupled to the connector is the sound collector plug or the sound output plug; a switching unit for selectively coupling the plug coupled to the connector to one of the sound compressor and the sound decompressor; and a controller for selectively switching of the switching unit according to an identification outcome, wherein the plug identification unit identifies multi-channel stereophonic sound if three or more audio input lines of the sound collector plug or three or more audio output lines of the sound output plug are identified with compression or decompression of sound.
