Abstract
For musical instruments or sound reproduction, it is important that the sound definition is as fine as possible. In the field of sound reproduction electroacoustic transducers provided with round diaphragms or electrostatic system tapes are used. There is no system which indicates if the generated sound is appropriate for the human ear. The method is a fractal shape which corresponds to the shape of the human ear. The method consists in a diaphragm which, just like the ear by its shape is a series of resonators with different frequencies. The shape of the diaphragm of said harmonic amplifier is characterised in that it comprises tongues originating from a common surface, like fingers of a hand originating from the palm. Said method is implemented by an apparatus consisting of a membrane digitised by tongues. The membrane is placed on the musical instrument. Another embodiment of the method consists in a membrane mounted on a sound frequency generator forming an electroacoustic transducer. The method and the apparatus can be used for all types of musical instruments and particularly in the whole of the audio and audio-visual field.
Description
MEMBRANES RÉSONATEURS A FRÉQUENCES DIFFÉRENTES RESONATOR MEMBRANES WITH DIFFERENT FREQUENCIES
Dans le domaine de la création des sons, ou de la reproduction des sons par l'usage de mécanisme électroacoustique, par des instruments 'de musique, il est utile que la définition sonore soit la plus intelligible.Les instrumentistes ont mis en oeuvre des objets sonores tel que les pianos ou violons, contre-basses, et instruments à vent, certains instruments prirent la renommée sur des critères de qualité acoustique, dont la qualité des harmoniques au même instant déterminent les timbres. L'auditiûn humaine est caractérisée par la perception simultanée de l'ensemble des harmoniques et des transitoires , ces critères correspondent à la forme de l'oreille par laquelle sont lus les sons. La forme de l'oreille est l'aspect mécanique de l'audition, le senseur, le capteur des informations . Le procédé est une forme fractale, qui répond aux résonances sonores de fréquences différentes inscrites physiquement par la forme de l'oreille humaine. Les sciences naturelles font remarquer les différentes formes d'oreilles liées aux différents spectres d'écoute de l'audition des animaux pour des appréciations du monde environnant différentes . Dans le domaine de la reproduction du son , il est fait usage des transducteurs électro acoustiques, munis de membranes rondes, coniques . Il est fait également usage de transducteur à ruban pour des systèmes électrostatiques . Le rendement acoustique est le premier paramètre quantifiable , mais aucun des systèmes n' indique si le son créé est bien ordonné en temps et qualité. Les musiciens indiquent que les transitoires ne sont pas retransmis . En effet les techniques actuelles manquent de précision . Le son émis peut être organisé codifié , formaté de façon à être plus structuré en chaque instant , plus complet, représentatif de la réalité sonore préhensible par l'oreille. Le présent procédé consiste à créer une forme de membrane, d'épaisseur constante ou variable pour la mise en phase des harmoniques et leur amplifications précises. Les notes sont réalisées par des languettes de dîmensions différentes et de résonance différentes, ce qui rend la lecture auditive très complète . Cette forme de membrane est active pour émettre la rapidité acoustique des harmoniques et des transitoires.
L'équilibre tonal est complet en chaque instant par la multitude d'informations sonores supplémentaires. La forme de la membrane est un ensemble de languettes résonateurs à fréquences différentes, nommé amplificateur d'harmoniques qui par sa forme est une série de résonateurs acoustiques a multiples fréquences différentes à chaque instant. La forme de la membrane est caractérisée par des languettes indépendantes, des résonateurs acoustiques, émanant d'une même surface , comme les doigts d'une main issus de la paume de la main. Cette membrane est fixée près d'un générateur de son, amplifiant par résonance mécanique les harmoniques.In the field of the creation of sounds, or the reproduction of sounds by the use of an electroacoustic mechanism, by musical instruments, it is useful that the sound definition is the most intelligible. The instrumentalists have implemented objects sound such as pianos or violins, double bass, and wind instruments, certain instruments gained fame on criteria of acoustic quality, the quality of the harmonics at the same time determining the timbres. Human hearing is characterized by the simultaneous perception of all the harmonics and transients, these criteria correspond to the shape of the ear by which the sounds are read. The shape of the ear is the mechanical aspect of hearing, the sensor, the sensor of information. The process is a fractal form, which responds to sound resonances of different frequencies physically registered by the shape of the human ear. The natural sciences point out the different shapes of ears linked to the different spectra of listening to the hearing of animals for different appreciations of the surrounding world. In the field of sound reproduction, use is made of electro-acoustic transducers, provided with round, conical membranes. Ribbon transducers are also used for electrostatic systems. Acoustic performance is the first quantifiable parameter, but none of the systems indicates whether the sound created is well ordered in time and quality. The musicians indicate that the transients are not retransmitted. Indeed, current techniques lack precision. The sound emitted can be organized codified, formatted so as to be more structured at each instant, more complete, representative of the sound reality graspable by the ear. The present method consists in creating a shape of membrane, of constant or variable thickness for the phasing of harmonics and their precise amplifications. The notes are produced by tabs of different dimensions and different resonance, which makes auditory reading very complete. This form of membrane is active to emit the acoustic speed of harmonics and transients. The tonal balance is complete at all times by the multitude of additional sound information. The shape of the membrane is a set of resonator tabs at different frequencies, called harmonic amplifier which by its shape is a series of acoustic resonators at multiple different frequencies at each moment. The shape of the membrane is characterized by independent tongues, acoustic resonators, emanating from the same surface, like the fingers of one hand from the palm of the hand. This membrane is fixed near a sound generator, amplifying the harmonics by mechanical resonance.

Cette membrane particulière est caractérisée par cinq languettes indépendantes, ou digitalisations , dont trois importantes (2) et deux petites (3) . Une dig'rtalisation supplémentaire (4) est un segment arrondi isolé . Une petite digitalisation (5) est placée sur le côté de l'ensemble . Les résonateurs formés par les languettes, ou la membrane peuvent être pourvus de trous (6).Cet appareil réalisé dans cet exemple non limitatif, en titane de 1/10 de millimètres d'épaisseur , d'une longueur de six centimètres est placé, dans un instrument de musique, par exemple dans un instrument à vent, posé à l'intérieur à proximité de l'évent, ou sur un violon.ou dans un piano. Une autre variante de cet appareil (Fig. 2) à résonateurs à fréquences différentes, est caractérisé par une membrane digitalisée (1) de vingt centimètres de long, montée sur un générateur de fréquence de son , créant un transducteur électro acoustique (2) d'une chaîne de reproduction sonore. Les segments servant d'appui au saladier (3), constituent ainsi un appareil électro acoustique d'une précision sonore remarquable. La membrane est réalisée en aluminium épais de trois millimètres vers le centre et affinée vers les extrémités des segments. Le procédé et appareil dit amplificateurs d'harmoniques, sont utiles aux instruments de musique et tout le monde de l'audio et l'audio visuel.

This particular membrane is characterized by five independent tabs, or digitalizations, of which three important (2) and two small (3). A dig additional rtalisation (4) is an isolated rounded segment. A small digitization (5) is placed on the side of the assembly. The resonators formed by the tongues, or the membrane may be provided with holes (6). This device produced in this nonlimiting example, made of titanium 1/10 of a millimeter thick, with a length of six centimeters is placed, in a musical instrument, for example in a wind instrument, placed indoors near the vent, or on a violin. or in a piano. Another variant of this device (Fig. 2) with resonators at different frequencies, is characterized by a digitized membrane (1) twenty centimeters long, mounted on a sound frequency generator, creating an electro-acoustic transducer (2) d 'a sound reproduction system. The segments serving as support for the salad bowl (3) thus constitute an electro-acoustic device with remarkable sonic precision. The membrane is made of aluminum three millimeters thick towards the center and refined towards the ends of the segments. The method and apparatus known as harmonic amplifiers, are useful for musical instruments and all of audio and visual audio.
