Patent
CA 2633370
A device for imparting vibration to a body is disclosed, such as may be used for whole body vibration treatment. In one embodiment, a pair of linear motors are disposed on a base. Each linear motor has a stator portion secured to the base and a moveable portion that linearly reciprocates with respect to the stator in response to a supplied current. A current source is electrically coupled to the linear motors for supplying alternating current to the linear motors. A controller is in communication with the current source for controlling movement of the linear motors at a selected phase relationship between the linear motors. A platform is coupled to the moveable portions of both linear motors using rigid rubber supports. The platform moves with respect to the base in response to movement of the linear motors. In a level mode, the dual linear motors are operated in phase, such that the platform remains level. In a tilt mode, the linear motors operate out of phase, imparting a vibrating tilt to the platform. A moveable mount, such as a rubber mount, couples the platform to the moveable portions of each linear motor to accommodate the tilt.
