CA 2352989

The generation of sounds by musical instruments or sound reproduction system is not perfect and the acoustic discord can be resolved. The invention concerns a method using open volumes such as a glass (1), optionally provided with a cut, a fracture (2) producing at least an orifice. Said object placed in the proximity or on a sound generator, releases additional sound waves in tune with the sound generator, by mechanical coupling or aerial sound linkage resulting from the resonator volume and its fracture. The invention also concerns an apparatus made of a material with Shore hardness higher than 60 enabling to transmit mechanical sound vibrations by having its leg (3) fixed to a piano (7). The method and apparatus constitute an improvement for the field of sound reproduction and generation.

La création des sons par des instruments de musique ou des systèmes de reproduction du son, n'est pas parfaite, des dissonances acoustiques inhérentes à la réalisation des générateurs de son peuvent être corrigées. Le présent procédé utilise des volumes ouverts tels que un verre (1) éventuellement aménagé d'une coupure, une fragmentation (2) créant au moins un orifice. Cet objet placé à proximité ou sur un générateur de son, dégage des ondes sonores supplémentaires en accord avec le générateur de son, par couplage mécanique ou liaison sonore aérienne due au volume du résonateur et sa fragmentation. Un appareil réalisé en matière supérieure à 60 de dureté Shore permet par son pied (3) fixé à un piano (7) de transmettre les vibrations mécanique sonores. Procédé et appareil son une amélioration utile pour le monde de la reproduction ou la création des sons.
