The present invention is directed to a pad and sound transmission system which is adapted to directly transmit audible sound waves into the body at high intensity levels. In one embodiment, the pad is comprised of a padding material and speakers disposed within the padding material. The sound transmission system includes an amplifier, an automatic volume control, and a plurality of input parts. The pad includes a padding material comprised of a layer of highly porous material, a layer made of more dense foam and a stiff foam core in which the speakers are connected. The padding material preferably includes a plurality of openings that form resonant chambers that direct sound- generated vibrations to the shoulder blades, the center of the spine, and the hips of the user.

L'invention concerne un matelas et un système de transmission de sons conçu pour transmettre directement des ondes sonores audibles dans le corps à des niveaux d'intensités élevés. Dans un mode de réalisation de cette invention, le matelas est constitué d'un matériau de matelassage et de haut-parleurs placés dans ce matériau de matelassage. Le système de transmission de sons comprend un amplificateur, une commande automatique du volume et plusieurs parties d'entrée. Ce matelas comprend un matériau de matelassage constitué d'une couche de matériau hautement poreux, d'une couche de mousse plus dense et d'une partie centrale de mousse rigide dans laquelle des haut-parleurs sont connectés. Le matériau de matelassage comprend de préférence plusieurs ouvertures formant des chambres de résonance qui dirigent les vibrations générées par les sons en direction des omoplates, du centre de la colonne vertébrale et des hanches de l'utilisateur.
