ABSTRACT:
A pulse action facial massager apparatus including a headset assembly for mounting to a user's head. A pair of flexible extension fingers extending from opposite sides of the headset assembly each of which is operably coupled to a vibrating device each generating an independent vibrating action. A tip portion of each extension finger is manually movable for selected contact at independent portions of the user's head. Hence, the respective vibrating device transmits the vibrating action thereof along the extension finger to the respective tip portion. Each vibrating device includes a motor that is controlled by an electronic controller mounted on the headset assembly. The controller permits user-variation of the repetition rate and duty cycle of the motors. This permits the user to vary the vibrational patterns produced by the present invention. In an automatic mode, duty cycle is automatically varied by a sawtooth waveform to produce a dynamically changing pattern of massage intensity. The control also includes a timer that after a preset time gradually diminishes the duty cycle and thus the intensity of the vibrations.
