Abstract: The present invention provides an electronic device having remote control functions, comprising a baseband circuit, a PWM circuit, and an external wireless transmitting circuit. The external wireless transmitting circuit includes a second I/O port and a wireless transmitting unit. The PWM circuit is disposed at the output of the baseband circuit; the driving signal is output according to the control signal output by the baseband circuit for enhancing the intensity of the control signal and thus further reducing the volume of the external wireless transmitting circuit. In addition, by adding an infrared contact part of the first I/O port, the electronic device can transmit the driving signal to the external wireless transmitting circuit via the infrared contact part. Alternatively, the electronic device can transmit the driving signal to the external wireless transmitting circuit via one of the plurality of audio contact parts of the first I/O port by switching.
