PURPOSE: A handsfree device for a mobile communication terminal is provided to confirm incoming and outgoing telephone numbers without confirming an LCD of the mobile communication terminal although the mobile communication terminal is located in a remote place. CONSTITUTION: A plug(110) is inserted into a jack connection hole(101) or a receptacle of a mobile communication terminal for inputting and outputting a voice signal and receiving a DTMF(Dual Tone Multi Frequency) signal of the mobile communication terminal. A speaker(112) outputs the voice signal inputted through the plug(110) to the outside. A microphone(113) and a hook button(114) receive an external voice signal and inputs the received voice signal to the plug(110). An LCD(116) displays the DTMF signal of the mobile communication terminal inputted through the plug(110).
