Patent ID: 8058774

Claim:
A piezoelectric generator comprising: a vibrating plate including a vibrating-plate main section, a first bend disposed at a first side of the vibrating-plate main section, and a second bend disposed at a second side of the vibrating-plate main section opposite the first side; a mass load member attached to a surface of the vibrating plate opposite to the piezoelectric element; a piezoelectric element disposed adjacent the vibrating-plate main section such that the piezoelectric element is positioned between the first and second bends, the piezoelectric element including a piezoelectric ceramic body and first and second electrodes, the piezoelectric ceramic body having first and second surfaces facing each other, the first and second electrodes being disposed on the first and second surfaces of the piezoelectric ceramic body, respectively; and a support member supporting the vibrating plate at a location outside the first and second bends of the vibrating plate relative to the piezoelectric element.
