PROBLEM TO BE SOLVED: To provide a vibration generator which controls a current with its simpler structure and reduces the number of parts. SOLUTION: The vibration generator is provided with a magnetic circuit 2; a coil 3 which is arranged in a magnetic field generated by the magnetic circuit 2; and an electric circuit 4 connected to the coil 3. In this case, a vibration is generated between the magnetic circuit 2 and the coil 3 by means of electromagnetic force generated by the magnetic field of the magnetic circuit 2 and the current applied to the coil 3 through the electric circuit 4. The electric circuit 4 is provided with a switch 9 which opens and closes by making use of the vibration between the magnetic circuit 2 and the coil 3. COPYRIGHT: (C)2004,JPO&NCIPI
