An electromagnet 21 is operated by a sensor switch 22 utilizing a sound sensor. When a spring 7 is wound by pulling a string 10 of a reel 11 and released, a spring gear 12 is rotated to rotate a stop rotor 18 which engages a stopper 20 to stop unwinding. When continuous voice or clapping is given, the sensor switch 22 is repetitively turned on and off and the stopper 20 is repetitively engaged with an disengaged from the stop rotor 18 to move the movable arm 2 finely intermittently. In the stoppage of voice, the rotation of the eccentric rotor 17 and the movement of the movable arm are stopped.
