Abstract
A vibration generating mechanism includes at least first and second permanent magnets spaced from each other with the same magnetic poles opposed to each other. The first permanent magnet is coupled to a link mechanism so that the drive force of a drive source may be transmitted to the first permanent magnet via the link mechanism. A periodic and reciprocating movement of the first permanent magnet relative to the second permanent magnet changes the opposing area thereof, causing vibration of the second permanent magnet.
