ABSTRACT:
A massage device capable of producing vibrating or reciprocating motions for massaging muscles of a person comprises a shell, enclosed at the upper and lower end by a pair of end plates, houses a coaxial central axle provided with a middle voice coil having a plurality of brushes. The brushes are each slidably mounted on a longitudinal electric brush axle through an insulting sleeve The inner wall of the shell is provided by upper, middle and lower sets of magnets, whereby an electric current flowing into the electric brush axles and the coils mounted thereon will produces a magnetic field interacting with the field by the magnets, urging the central axle to move in the longitudinal direction. Since the current is alternating, the associated motion of central axle is reciprocating, ready for the purpose of massage.
