<p>[Object] An object is to obtain a piezoelectric power generator that generates a large amount of electric power by amplifying a displacement of a generating device. [Solution] A piezoelectric power generator A includes a resonator 10 including a first weight member 13 supported on a base member 11 via a spring means 12; a second weight member 23; and a generating device 20 including a vibrating plate 21 having a piezoelectric element 22 attached to a principal surface thereof, the vibrating plate 21 having one end 21a secured to the first weight member 13 and the other end being a free end to which the second weight member 23 is attached, the generating device 20 being capable of bending and vibrating in an up-and-down direction. The first weight member 13 swings at a predetermined frequency about an axis perpendicular to a bending vibration plane of the generating device 20. Thus, it is possible to generate a larger amount of electric power than in the case of the generating device alone.</p> |
