Description

AMPLIFICATEUR HARMONIQUE ET TRANSDUCTEUR ELECTRO-ACOUSTIQUE HARMONIC AMPLIFIER AND ELECTRO-ACOUSTIC TRANSDUCER
CORRESPONDANTCORRESPONDING
II est dans le monde de la reproduction du son, usuel d'utiliser des membranes excitées par des moteurs à aimants ou des systèmes électro- statiques à ruban.It is customary in the world of sound reproduction to use membranes excited by magnet motors or electrostatic ribbon systems.
Il est habituel d'identifier ces produits par des rendements acoustiques et des vitesses d'accélération.It is usual to identify these products by acoustic yields and acceleration speeds.
Tous ces produits ont des masses importantes en mouvements pour produire le son. Par opposition, le son est un choc entre particules de l'air qui ont des masses infiniment petites qui confèrent des vitesses de propagations sonores élevées, environ 300 mètres seconde.All of these products have large masses in motion to produce sound. In contrast, sound is a shock between particles of air which have infinitely small masses which confer high speeds of sound propagation, approximately 300 meters second.
Un produit tel que l'enceinte au plasma était proche des performances physiques de l'air puisqu'il agissait au niveau des particules de l'air. L'inconvénient de ce procédé passait par une transformation chimique de la composition de l'air et pour cela les moyens de mise en oeuvre étaient relativement coûteux.A product such as the plasma enclosure was close to the physical performance of air since it acted on the level of air particles. The disadvantage of this process was a chemical transformation of the air composition and for this the means of implementation were relatively expensive.
Le présent procédé est un complément aux systèmes de reproduction sonore actuels tels que les enceintes acoustiques utilisées. Ces enceintes créent les bases sonores nécessaires mais sans aucun raffinement, et notamment ont un défaut caractéristique qui est le non respect de l'intermodulation sonore. Le présent procédé et appareil superpose au signal sonore grossier des enceintes, l'information sonore fine contenue dans le signal électrique audio d'origine. Cette information sonore est l'amplification et l'ordre précis des harmoniques dans l' espace-temps. Le présent procédé utilise l' électro-magnétisme de faible niveau qui s'appuie sur les particules de l'air ambiant créant ainsi un nouveau champ magnétique sur le champ magnétique terrestre. Ainsi les particules de l'air sont agitées par le nouveau champ magnétique variable en opposition au champ magnétique terrestre de référence stable.The present method is a complement to the current sound reproduction systems such as the loudspeakers used. These speakers create the necessary sound bases but without any refinement, and in particular have a characteristic defect which is the non respect of the sound intermodulation. The present method and apparatus superimposes the coarse sound signal of the loudspeakers, the fine sound information contained in the original audio electric signal. This sound information is the amplification and the precise order of the harmonics in space-time. The present method uses low level electromagnetism which is based on the particles of the ambient air thus creating a new magnetic field on the terrestrial magnetic field. So the air particles are agitated by the new variable magnetic field in opposition to the stable reference earth magnetic field.
Le nouveau champ magnétique est défini par l'usage unique d'au moins un solénoïde excité, activé par le signal sonore électrique audio, d'un amplificateur acoustique.The new magnetic field is defined by the single use of at least one excited solenoid, activated by the electrical audio sound signal, of an acoustic amplifier.
Ainsi, le présent procédé amplifie les harmoniques sonores de faible niveau mais de grande importance pour la perception auditive et permettent ainsi une reproduction du son très claire. La rapidité d'exécution sonore de ce procédé est caractérisée par l'absence d'inertie et de trainage mécanique car exécutée par le solénoïde, sans mouvement mécanique apparent. L'émission sonore est ainsi réalisée par l'agitation des molécules dans l'espace d'une part et peut, d'autre part, suivant les types ou modes d'enroulements, être réalisée par les micro-vibrations sonores des fils électriques du ou des solénoïdes. Une variante du procédé est un solénoïde additionné d'au moins un aimant à l'intérieur ou à l'extérieur, qui active son effet mais en diminue la sensibilité du fait de la rémanence du champ magnétique de l'aimant qui impose sa constante de champ magnétique, masquant le champ magnétique terrestre. Ce procédé est caractérisé par un appareil constitué (Fig 1) par au moins un enroulement de fils électriques (1) dans ce cas de figure, l/10ème de millimètre enroulé sur un support souple (2) en polymère de 10 cm de long et 0.8 cm de diamètre. L'impédance de cet enroulement est de 8 Ohms, l'enroulement est caractérisé en ce que chaque couche (3, 4) est enroulée dans le même sens de bobinage, le fil de retour (5) étant placé le long du bobinage. Ce mode de bobinage permet des micro-vibrations entre les spires, étant donné la différence de tension entre les spires de la première et deuxième couche. Ces micro-vibratioήs participent à l'amplification sonore des harmoniques. Cet appareil est couplé à un signal électrique audio d'une enceinte acoustique ou d'une alimentation acoustique. Cet appareil vient en complément de transducteurs électro-acoustiques usuels. Cet appareil est réalisé par un homme de l'art et représente un exemple non limitatif de réalisation de ce procédé. Cet appareil (Fig 1) est intégré (Fig 2) dans une enceinte acoustique (8) devant la façade (1). Le solénoïde transducteur électro-acoustique (2) du présent appareil est monté libre dans l'air ambiant à côté du Tweeter (3). Il est monté sur la façade tenu mécaniquement par deux vis (4) et est monté électriquement avec le Tweeter (3) par les fils électriques (5, 6) provenant du filtre électro-acoustique (7). L'enroulement du fil électrique peut avoir n'importe quelle type de forme, par exemple de section ronde, conique, carrée ou toute autre forme. Ce montage n'est pas exhaustif de l'application de l'appareil. Ce nouveau transducteur électro-acoustique pourrait être monté directement sur l'alimentation générale audio entre l'ampli et l'enceinte acoustique. Ces nouveaux transducteurs électro-acoustiques peuvent être montés entre eux en série ou en parallèle ou les deux. Ces transducteurs acoustiques sont des amplificateurs harmoniques.Thus, the present process amplifies the sound harmonics of low level but of great importance for the auditory perception and thus allow a very clear reproduction of the sound. The speed of sound execution of this process is characterized by the absence of inertia and mechanical drag as executed by the solenoid, with no apparent mechanical movement. The sound emission is thus produced by the agitation of the molecules in space on the one hand and can, on the other hand, depending on the types or modes of windings, be produced by the sound micro-vibrations of the electrical wires of the or solenoids. A variant of the method is a solenoid with at least one magnet inside or outside, which activates its effect but reduces its sensitivity due to the remanence of the magnetic field of the magnet which imposes its constant of magnetic field, masking the earth's magnetic field. This process is characterized by an apparatus consisting (Fig 1) of at least one winding of electric wires (1) in this case, 1/10 of a millimeter wound on a flexible support (2) made of polymer 10 cm long and 0.8 cm in diameter. The impedance of this winding is 8 Ohms, the winding is characterized in that each layer (3, 4) is wound in the same winding direction, the return wire (5) being placed along the winding. This winding mode allows micro-vibrations between the turns, given the voltage difference between the turns of the first and second layer. These micro-vibratio ή s involved in the amplification of sound harmonics. This device is coupled to an audio electrical signal from a acoustic enclosure or acoustic power supply. This device complements the usual electro-acoustic transducers. This device is produced by a person skilled in the art and represents a non-limiting example of carrying out this process. This device (Fig 1) is integrated (Fig 2) in an acoustic enclosure (8) in front of the facade (1). The electro-acoustic transducer solenoid (2) of this device is mounted free in the ambient air next to the Tweeter (3). It is mounted on the facade mechanically held by two screws (4) and is electrically mounted with the Tweeter (3) by the electrical wires (5, 6) coming from the electro-acoustic filter (7). The winding of the electric wire can have any type of shape, for example of round, conical, square or any other shape. This assembly is not exhaustive of the application of the device. This new electro-acoustic transducer could be mounted directly on the general audio power supply between the amplifier and the acoustic enclosure. These new electro-acoustic transducers can be mounted together in series or in parallel or both. These acoustic transducers are harmonic amplifiers.
Le présent procédé et appareil électro-acoustique limité à un enroulement de fil électrique sans membrane donne une finesse acoustique inégalée. Plusieurs enroulements l'un sur l'autre constituent également un transducteur électro-acoustique de même nature que celui présenté dans le présent procédé, de réalisation plus complexe.The present electro-acoustic method and apparatus limited to a winding of electric wire without a membrane gives an unequaled acoustic finesse. Several windings one on the other also constitute an electro-acoustic transducer of the same kind as that presented in the present process, of a more complex embodiment.
Cet appareil et procédé sont utilisables sur tous les systèmes audio, audiovidéo et tout mode de communication tel que téléphones, radio, ainsi que par le monde médical pour l'améloration du confort auditif des malentendants. This device and method can be used on all audio systems, audiovideo and any mode of communication such as telephones, radio, as well as by the medical world for improving the hearing comfort of the hearing impaired.
