Definitions
- the document FR-A-2,521,808 discloses a ribbon speaker comprising a permanent magnet defining a gap in which is disposed a ribbon. The free ends of the ribbon are connected to electrical contacts. According to one embodiment, the ribbon consists of a series of strips that can be wound on a flexible support.
- a product such as the plasma chamber was close to the physical performance of the air since it acted on the particles of the air.
- the invention provides an apparatus according to claim 1 and its use as defined in claim 4, as well as a system as defined in claim 5.
- the other claims define preferred embodiments.
- the present apparatus complements 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 intermodulation sound.
- the present method and apparatus superimposes the coarse sound signal of the speakers,
- This sound information is the amplification and precise order of the harmonics in space-time.
- the sound emission is thus carried out by the sonic micro-vibrations of the electrical wires of the solenoid (s).
- a variant of the apparatus is a solenoid supplemented with at least one magnet inside or outside, which activates its effect but decreases its sensitivity due to the remanence of the magnetic field of the magnet which imposes its Magnetic field constant, masking the Earth's magnetic field.
- the apparatus is constituted ( Fig 1 ) by at least one winding of electrical wires (1) in this case of figure 1 / 10th 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 difference in voltage between the turns of the first and second layers. These micro-vibrations participate in the sound amplification of the harmonics.
- This device is coupled to an audio electrical signal of a acoustic enclosure or an acoustic power supply.
- This device comes in addition to usual electro-acoustic transducers.
- This apparatus is made by a person skilled in the art and represents a non-limiting example of embodiment of this method.
- This device ( Fig 1 ) is integrated ( Fig 2
- the electroacoustic transducer solenoid 10 of the present apparatus is freely mounted in the ambient air next to the tweeter 11. It is mounted on the facade mechanically held by two screws 12. and is electrically mounted with the tweeter 11 by the electrical wires (5, 6) from the electro-acoustic filter (7).
- the winding of the electric wire can have any type of shape, for example 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 supply between the amp and the speaker.
- These new electro-acoustic transducers can be connected together in series or in parallel or both.
- These acoustic transducers are harmonic amplifiers.
- the present method and electro-acoustic apparatus limited to a winding of electric wire without membrane gives an unmatched acoustic fineness.
- This apparatus and method can be used on all audio, audio-video and all communication systems such as telephones, radio, as well as by the medical world for improving the hearing comfort of the hearing impaired.

Description
- II est dans le monde de la reproduction du son, usuel d'utiliser des membranes excitées par des moteurs à aimants ou des systèmes électrostatiques à ruban.
- Le document
FR-A-2 521 808 - Il est habituel d'identifier ces produits par des rendements acoustiques et des vitesses d'accélération.
- 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 propagation sonore élevées, environ 300 mètres par seconde.
- 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.
- L'invention propose un appareil selon la revendication 1 et son utilisation telle que définie dans la revendication 4, ainsi qu'un système tel que défini dans la revendication 5. Les autres revendications définissent des modes de réalisations préférés.
- Le présent appareil 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.
- L'émission sonore est ainsi réalisée par les micro-vibrations sonores des fils électriques du ou des solénoïdes.
- Une variante de l'appareil 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.
- L'appareil est constitué (
Fig 1 ) par au moins un enroulement de fils électriques (1) dans ce cas defigure, 1 /10ème de millimétré 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 caractérise 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-vibrations 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 9. à Le solenoïde transducteur électro-acoustique 10 du présent appareil est monté libre dans l'air ambiant à côté du Tweeter 11. Il est monté sur la façade tenu mécaniquement par deux vis 12 et est monté électriquement avec le Tweeter 11 par les fils électriques (5, 6) provenant du filtre électro-acoustique (7). L'enroulement du fil électrique peut avoir n'importe quel 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.
- 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.
- Cet appareil et procédé sont utilisables sur tous les systèmes audio, audio-vidéo et tout mode de communication fel que téléphones, radio, ainsi que par le monde médical pour l'améloration du confort auditif des malentendants.
