Abstract
A vibrating plate apparatus including a vibrating plate on which a user rests, a vibration motor member connected to the vibrating plate, several air cushions provided under the vibrating plate for dampening vibration, and an air tank in communication with each of the air cushions. The tank establishes the air pressure in at least one of the air cushions at a predetermined value independently from the user's weight. The motor member includes two motors rotating in opposite directions, each of the two motors including a set of flyweights driven by the two motors and having a center of gravity offset relative to the axis, the two sets having the same mass, being symmetrical to each other and including at least one moveable flyweight that can assume at least one position to vary the vibrating plate's vibration amplitude.
