Abstract: A multi-functional automatic circular massaging device including at least a pair of motors respectively disposed in a pair of housings to rotatively drive cams for creating a vibrating massaging effect, a soft pad formed with two lateral recesses for receiving the housings, a heating coil sandwiched between two layers of unwoven fabrics, a surface layer covering the soft pad, and a controlling box connected to the motors and an external power source. The surface layer is formed with alternating X-shaped protuberances and spherical bosses and alternating long and short rod-like protuberances disposed on four side edges of the surface layer. The controlling box includes a circuit board having a specific chip which controls the motors to output varying power at a predetermined time interval, creating sequential automatic circularly varying at least eight stages of massaging effect from strongest stage to weakest stage.

Abstract: An electromechanical apparatus is disclosed herein such as a cushion, pad or mattress, including pulsing elements for massaging a variety of body locations having a plurality of vibrating transducers situated in groups within a cushioned member so that the groups of transducers operate in given locations or sections of the cushioned member to provide either an automatic or manually controlled rolling or travelling vibratory motion across the member. A manually operated dwell of the vibratory motion is provided at selected locations. A handheld controller supplies the groups of transducers with electrical signals to produce an operating sequence of vibratory oscillations in individual transducers as well as selected groups and the aforementioned rolling or travelling vibratory motion.

Abstract: An improved vibrating massage apparatus in the form of an elongated pad incorporating a plurality of independently controllable vibrating members to impose vibratory oscillations along the full extent of the apparatus. Each vibrating member includes a motor having a pair of rotatable shafts extending outward therefrom in axial opposition to one other, a fixed eccentric weight being secured at the end of each shaft. Each vibrating motor is secured within a housing, the outer surface thereof extending outwardly into a planar flange. The planar flanges of the motor housings are imbedded within a unitary foam member which substantially defines the shape of the pad. An electrical switching circuit sequentially activates and deactivates each of the vibrating motors in a predetermined manner.

Abstract: A multi-function cushion is provided having a slip cover, a soft pad enclosed within the slip cover, and having a plurality of magnets on the front side. A control panel with an outer instruction cover coupled to an inner housing chamber is disposed within a recess formed in the soft pad. The control panel includes a vibration switch, a heating switch and a power socket. A heating device is mounted between the front side of the soft pad and the slip cover, and is electrically connected with the heating switch of the control panel. A vibration motor disposed in the rear side of the soft pad is electrically connected with the vibration switch and the power socket of the control panel. A pressure switch is installed in the rear side of the soft pad and electrically connected with the power socket, the vibration switch and the heating device, whereby the cushion not only can support the user's lumbar region, but can also provide heating and massaging effects, and magnetic stimulation of the user.

Abstract: A massaging cushion device used in a car, which included a hollowed frame of suitable size. The frame is connected onto a seat in a car. On both lateral sides of the frame there are two massaging devices movably connected therewith. The ends of the massaging devices extend into the lateral sides respectively for pivotal connecting therewith. A plurality of driving structures are provided on one side of each of the massaging devices. The massaging devices are capable of being spread out about the pivot, and are capable of folding for storage in the hollowed interior of the frame.

Abstract: A neck pillow with internal vibrational mechanisms comprising a pillow positionable over a curved indentation at the edge of a shampooing sink, the pillow having a curved central extent to conform with the indentation of the sink and downwardly extending legs positionable interiorly and exteriorly of the sink, the pillow being of a waterproof external material configured to seal the interior of the pillow; and a plurality of vibrational balls secured together in a planar array beneath the foam, the balls being configured in a plurality of rows with the balls of each of the rows coupled by laterally extending wires with springs at the opposite ends thereof coupled to the lateral ends of the pillow, the central balls of the rows being hollow with a rotatable rod extending therethrough and with an eccentric within each central ball coupled for rotation with the rotation of the rod.

Abstract: A vibrating neck rest particularly adapted for attachment to and use in conjunction with a passenger seat a motor vehicle, the vibrating neck rest including a cushion, the cushion being substantially elongated and having a major longitudinal axis, a vibration unit disposed within the cushion for producing a vibration on at least a portion of a surface of the cushion, a pair of tubes, one each of the pair of tubes extending outward from an opposing side of the vibration unit, the pair of tubes extending outward from the vibration unit substantially parallel to the major longitudinal axis of the cushion, a pair of hammer members, one each of the hammer members being attached to a distal end of one each of the tubes, an attachment apparatus for attaching the cushion to the passenger seat of the motor vehicle, and a control mechanism for altering at least one characteristic of the vibration produced by the vibrating apparatus, the control mechanism being movable to a point remote from the cushion.

Abstract: A hollow member having a continuous sound-waveguide therein is formed by a plate shaped rigid base member microwave welded to an overriding member of flexible and semi-rigid plastic made, e.g., by vacuum forming. A speaker and an amplifier are confined in the hollow member which is filled with gas. The shape, material and thickness of the hollow member is selected to have a strength capable of retaining the shape of a sound-waveguide without an airpressure within the hollow member against reasonable external forces imposed, such as when under the usual condition of use on the back or seat of a chair.

Abstract: A device for enhancing enjoyment of electronically reproduced music including a chair with liquid-filled bladders coupled to transducers such as electromagnetic driver assemblies responsive to audio-frequency electrical signals. A diaphragm of elastic sheet material provides support for part of the bladder and part of the transducer. Bladders and transducers are located in the seat and back of the chair, and the transducers move the liquid in the bladders, so that movement of the liquid can be felt by a user sitting in the chair. The electrical signals are preferably filtered to pass only bass frequencies to the transducers.
