Patent ID: 7687697

Claim:
A method for manufacturing a sound panel for playing sounds and music, characterized in that it comprises the steps of: building a soundboard out of wood, which is substantially flat and has a preset shape, said building comprising: drawing said preset shape, gluing together a plurality of wooden strips arranging them on a single layer so as to form substantially the drawn preset shape and so that the fiber of the wood is substantially directed along a long side or a long diagonal of the drawn preset shape, the grain of said wooden strips being not parallel to the larger surface of the strips; determining an intrinsic vibration frequency of the soundboard; determining a nodal point of vibration of the soundboard; performing a frequency mapping on the surface of the soundboard in order to determine peaks of intensity in an audio frequency range along the surface of the soundboard; modifying the thickness of areas of the soundboard selected according to the value of the peaks of intensity obtained at the various frequencies; applying, to said soundboard, at least one tie having such a dimension and radius of curvature as to apply a mechanical tension to said soundboard; forming a seat inside the soundboard in said nodal point; mounting an electromechanical transducer within said seat, in order to transduce into mechanical pulses and consequent vibrations of the soundboard audio information which arrives from an electronic audio source in the form of electrical signals.
