PURPOSE: A piezoelectric generator is provided to generate power using magnetic force in a contactless rotation manner. CONSTITUTION: A rotary shaft passes through a case(100). A rotary plate(300) comprises a pair of rotary plate iron pieces, and a magnet interposed between the pair of rotary plate iron pieces. The rotary plate is combined with the rotary shaft. The rotary shaft passes through a hole formed in the center of a circuit board(400). The printed circuit board is supported by a support stand(700). Multiple power generators are perpendicularly stood on the printed circuit board. The power generator comprises a vibration plate iron pieces(510), a piezoelectric body(520), and a vibration plate(530). |
