PURPOSE: A handsfree having a lip sync function is provided to make a doll to perform a lip sync according to a voice of the other party outputted from a handsfree when a call communication is made with the other party. CONSTITUTION: A terminal(1) performs a voice or character communication function wirelessly with a terminal of the other party. A handsfree(2) amplifies a voice input signal of a user at a remote area, transmits it to the terminal, amplifies a voice signal of the other party outputted from the terminal(1), and outputs the amplified voice signal to a speaker. A motor driver(3) drives a motor according to the voice signal of the other party inputted through a voice output line of the handsfree(2). A doll(4) converts a rotary force of the motor into a reciprocal motion and performs a lip sync function.
