A mobile communication device including a connector, a judging circuit, a first transmission circuit, a second transmission circuit, a data processing module and an audio processing module is provided. The first end of the connector is for receiving and transmitting a data signal of the data processing module or an audio signal of the data processing module. The second end of the connector is for receiving and transmitting the data signal of the data processing module or the audio signal of the data processing module. The judging circuit is coupled to the first end of a connector and outputs a first indicative signal to determine the type of the plug connected to the connector.
