PURPOSE:To improve interest and operability in a fan which has a fan body opened and a case body gripped and swung to swing a swing arm supporting the fan body and close a switch for operatively generating a voice from a voice generator. CONSTITUTION:After a swing arm 11 is made pivotable about a shaft part 15 while a fan body 1 is opened, a case body 21 is gripped to swing the fan body 1. Then, the swing arm 11 is swung about the shaft part 15 and a switch operating part 16 repetitively presses an actuator 34 of a switch 33. Every time the actuator 34 is pressed, the switch 33 is closed and the voltage of a power battery 32 is applied to a piezoelectric vibrator element 50 through reactance 46. When the voltage is applied to the piezoelectric vibrator element 50, the piezoelectric vibrator element 50 is displayed to generate a signal in a feedback electrode F in an instant of the displacement. The signal is applied to the base of a transistor 47 so that the transistor 47 is made non-conductive. Then, the transistor is made again conductive to apply the voltage to the piezo-electric vibrator element 50, so that self-oscillation is generated by the repetition of the operation to produce a sound. |
