Title:
VIBRATION GENERATOR
Document Type and Number:
WIPO Patent Application WO/1998/019383
Kind Code:
A1
Abstract:
An inexpensive vibration generator which does not consume much electric power and has a small size and a long service life is provided with fixed permanent magnets (3 and 4) fixed to both ends of a cylindrical enclosure (1), a mobile permanent magnet (5) housed in the hollow section (2) of the enclosure (1), and a driving coil (6) which is provided on the outer circumference of the enclosure (1) to generate magnetism when the coil (6) is energized with electric power from a pulsative power source (7). The generator vibrates when a driving force generated by the changes of the magnetism generated from the coil (6) and magnetic fluxes from the fixed permanent magnets (3 and 4) and mobile permanent magnet (5) is applied to the mover (5) of the mobile permanent magnet (5) to allow the magnet (5) to make reciprocating motions in the hollow section (2) of the enclosure (1).
