Abstract

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.

Description

RESONATEUR ACOUSTIQUE A VOLUME OUVERT TROUE -La création des sons par des instruments de musique ou des systèmes de reproduction sonore.n'est pas parfaite, des dissonances acoustiques ou insuffisances sonores inhérentes à la création des générateurs de son peuvent être corrigées, pour un son total , plein. -Le présent procédé utilise les caractéristiques sonores d'un volume ouvert tel que un vase en terre ou un verre, aménagé éventuellement d'au moins une coupure une fragmentation, créant un orifice qui peut être décentré par rapport à l'axe principal virtuel de l'objet. . Cet objet, exité par la proximité ou placé sur un générateur de son, dégage des ondes sonores supplémentaires en accord avec le générateur de son par couplage mécanique ou par resonnance des ondes aériennes due au volume et de la fragmentation du résonateur fixe en un emplacement défini. La qualité sonore globale est plus riche et plus précise. Un grand vase, avec l'orifice à sa base, par resonnance du volume, peut modifier l'acoustique d'une salle d'écoute.Le présent procédé est un résonateur acoustique fixe qui améliore les créations de son, d'un générateur de son, ou équilibre l'aspect tonal d'une salle. Le présent procédé est réalisé par un appareil en quartz, de la forme d' un verre (1) qui est coupé (2) près de sa base comme le montre (Fig. 1) . Dans cet exemple non limitatif de réalisation du procédé, l'addition d'un pied creux (3) permet à l'air de circuler de l'intérieur du volume (4) à la fin du pied (5).Ces circulations d'air en vibration sonore par le résonateur ainsi constitué sont utiles.les unes indépendantes des autres s'ajoutant ainsi aux qualités sonores de l'instrument .Ce pied permet de fixer ce résonateur dans un support (6) en laiton qui fixé sur un piano (7) transmet les vibrations mécaniques sonores.L'acoustique des résonateurs est excellente avec des matières rigides telles que le cristal, le verre et les métaux ou les alliages comme le bronze. Les matières telles que les céramiques sont également bonnes. Les matières dont la dureté est supérieure à 60 dureté Shore permettent de réaliser l'appareil . Les formes peuvent être (Fig.2) homogènes, mais pas symétriques. Procédé et appareil sont une amélioration utile pour le monde de la reproduction ou la création des sons.  OPEN HOLE VOLUME ACOUSTIC RESONATOR -The creation of sounds by musical instruments or sound reproduction systems is not perfect, acoustic dissonances or sound insufficiencies inherent in the creation of sound generators can be corrected, for a sound total, full. -The present process uses the sound characteristics of an open volume such as an earthen vase or a glass, possibly fitted with at least one cut, a fragmentation, creating an orifice which can be off-center with respect to the virtual main axis of the object. .

The overall sound quality is richer and more precise. A large vase, with the orifice at its base, by resonance of the volume, can modify the acoustics of a listening room. The present process is a fixed acoustic resonator which improves the creations of sound, of a generator. sound, or balances the tonal aspect of a room. The present process is carried out by a quartz apparatus, in the form of a glass (1) which is cut (2) near its base as shown (Fig. 1). In this nonlimiting example of embodiment of the method, the addition of a hollow foot (3) allows the air to circulate from the interior of the volume (4) to the end of the foot (5). air in sound vibration by the resonator thus constituted are useful. the ones independent of the others thus adding to the sound qualities of the instrument.
