Abstract
A piezoelectric bimorph element two piezoelectric elements to produce an electromotive force by imparting a stress to respective piezoelectric elements. The piezoelectric bimorph element is arranged in an oscillator such that the piezoelectric bimorph element is deformed in the electromotive force generating direction. An electrode having a predetermined area connected with a good electric conductor which is connected to conduct a current generated from the piezoelectric bimorph element is arranged at a patting part interlocked with the oscillator to oscillate. An electrode of opposite pole is connected with the piezoelectric bimorph element through the good electric conductor and arranged at a handle to be coupled with the oscillator, and a rectifier for rectifying an AC electromotive force generated by oscillating the oscillator is arranged to connect the good electric conductors which are connected with both electrodes.
