<P>PROBLEM TO BE SOLVED: To provide an oscillating generator that is superior in efficiency of power conversion though its case is compact, and can boost an output voltage, related to the oscillating generator which converts motion energy generated by vibration at reciprocation into power. <P>SOLUTION: The oscillating generator includes coils, the cylindrical case to which the coils are wound, fixed bodies arranged at both ends of the case, and a magnet body which includes magnetized magnets and is arranged so as to be reciprocative between the fixed bodies along the internal face of the case. In one or both the fixed bodies, there are arranged piezoelectric generation units which include piezoelectric elements and are arranged so as to be approachable to the magnet body, and coil electromotive forces generated at the coils and piezoelectric electromotive forces generated at the piezoelectric elements of the piezoelectric generation unit are output. <P>COPYRIGHT: (C)2011,JPO&INPIT |
