<P>PROBLEM TO BE SOLVED: To provide a vibration-force power generator capable of keeping efficiency of power generation by a piezo electric element even if diaphragms are harder in material than the piezo electric element. <P>SOLUTION: A vibration force power generator 1 which generates power with pressure fluctuation caused by vibration comprises: diaphragms 20a and 20b disposed with a space 50 therebetween; and a piezo electric element 10 for interconnecting the diaphragms 20a and 20b. Each of the diaphragms 20a and 20b are formed in a rectangular parallelepiped shape. In order to equalize the longitudinal directions of the diaphragms 20a and 20b, the diaphragms 20a and 20b are arranged side by side along an identical straight line, and the piezo electric element 10 interconnecting the end faces of the diaphragms 20a and 20b facing each other across the space 50 is disposed between the end faces of the diaphragms 20a and 20b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
