Abstract
A novel electromagnetic vibration generator, wherein a coil member capable of generating magnetic line of force and its magnetic counterpart are placed in parallel and united in one body in such a manner that the coil member and magnetic counterpart form a uniform gap, is disclosed. A coil member and a vibration plate are feasible as the magnetic counterpart. The vibration generator is driven by supplying an alternating current to the coil member so that a set of coil member successively attract or repel each other, or that the magnetomotive force of single coil member successively attracts the vibration plate. The vibration generator is vibrotherapeutically effective in the vibration frequency range of 50-80 times/sec, and 100-280 times/sec.
