Piezoelectric generator, electronic equipment and portable equipment

摘要

PROBLEM TO BE SOLVED: To use small-sized piezoelectrics which are high in generation efficiency and which cause piezoelectric effect. SOLUTION: This piezoelectric generator 100 comprises piezoelectrics which produce piezoelectric effect, displacing means 160, 161 which provide the piezoelectrics with displacement, and a means which supplies power produced at the piezoelectrics. The piezoelectric generator 100 is so designed that mechanical distortions produced in one of the piezoelectrics 170, 180 by the displacing means causes mechanical distortions to occur in the other piezoelectrics 170, 180 by means of a reaction force the mechanical distortion in the one of the piezoelectrics 170, 180.
