PURPOSE: A mobile communication terminal having an one-touch winding type ear-microphone used as a speaker is provided to easily carry and keep the ear-microphone, and prevent a connecting line from being twisted. CONSTITUTION: An ear-microphone(20,30) outputs signals demodulated by a terminal and provides input signals so that the terminal transmits modulated signals through a mobile communication network to be used as an earphone and a speaker. A connecting line(40) connects the terminal with the ear-microphone(20,30). A containing element is installed to contain the connecting line(40) inside the terminal. A winching element secures the expansion of variable length when the connecting line(40) is drawn out, and winds the connecting line(40) into the terminal. A control element downwardly controls output of the ear-microphone(20,30) to be corresponded to the earphone function in the case of drawing out the connecting line(40), and upwardly controls output of the ear-microphone(20,30) to be corresponded to the speaker function in the case of drawing in the connecting line(40).
