The control module is electrically connected to the acoustic wave sensors and the vibrators. Each acoustic wave sensor is driven by a sound signal generated by an external object to generate a response signal, the control module receives and compares the response signals to recognize the direction of the external object, and controls the vibrator to generate the vibration signal.
