PROBLEM TO BE SOLVED: To provide a vibration generator of simple structure, manufacturable with an easy technology. SOLUTION: A magnetic body is fitted to one end of a pipe made of a non-magnetic body; a magnetic body easily slidable inside the pipe is loosely inserted thereinto as a vibrator with a same pole and faced to the magnetic body; and an electromagnet is inserted into the other pipe end. By carrying AC current to the electromagnet, magnetic poles of the core of the electromagnet are alternately reversed to provide reciprocating movement of the vibrator. COPYRIGHT: (C)2006,JPO&NCIPI
