ABSTRACT:
A vibratory therapeutic cushion using multiple vibrator units enclosed in a flexible supple cushion, in a blanket-like pad or in a seat, each vibratory unit composed of an electrical coil slidably mounted in a magnetic field of a permanent magnet, the coil being supplied by an electrical oscillator with alternating electrical current or pulses of current at selectable magnitudes and frequencies, inducing vibrations in the coil which are transmitted to plates, one attached to the magnet assembly and one to the coil. The plates transmit the vibrations to the enclosure. The combination of vibrator units distributed in the seat produce uniformly distributed vibrations of desired intensity and frequency to vibrate the skin, muscles or internal organs as desired.
