<P>PROBLEM TO BE SOLVED: To provide a generator in which a voltage generated from a piezoelectric element is taken out efficiently. <P>SOLUTION: The generator comprises a piezoelectric vibrator 1 supported flexibly by supporting shafts 1a and 1b inserted into a round hole 1c and an oval hole 1d centering the nodes 2a and 2b of bending oscillations 11a and 11b being generated in the vibrator; piezoelectric elements 3a and 3b stuck on the antinodes of bending oscillations 11a and 11b of the piezoelectric vibrator 1; a forced oscillating part 4 having a magnet 8 fitted in the upper surface and coupled with the piezoelectric vibrator 1 through a spring 5; and a columnar rotator 9 having four magnets 10 fitted in the outer circumferential surface in the direction of the central axis. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
