ABSTRACT:
The present invention provides a method and portable apparatus for massaging particular portions of the body. In one embodiment, the invention comprises a face mask made out of a pliable member and having a plurality of compressible fingers mounted on the inner surface of the face mask for contacting and massaging the face portion. The vibrations are generated by a plurality of coaxially arranged, separately energized motors having weights slidably mounted for radial movement to the shafts of the motors. The motors can be energized through a pulse generating network which supplies power having an oscillating amplitude which produces a corresponding oscillation of the speed of the motors. By setting the speeds of the motors so as to produce beats, a complex vibrational wave is generated in which the vibrational beat frequency is modulated by or modulates the oscillating amplitude of the speed of the motors.
