Abstract
Il est dans le monde de la reproduction du son, usuel d'utiliser des membran es excitées par des moteurs à aimants ou des systèmes électrostatiques à ruban. Tous ces produits ont des masses importantes en mouvement pour produire le son. Par opposition, le son est un choc entre particules de l'air qui ont de s masses infiniment petites qui confèrent des vitesses de propagations sonores élevées. Le présent procédé utilise l'électromagnétisme de faible niveau qui s'appuie sur les particules de l'air ambiant créant ainsi un nouveau champ magnétique. Ce procédé est caractérisé par un appareil constitué par au moin s un enroulement de fils électriques (1) enroulé sur un support souple (2) en polymère. L'impédance de cet enroulement est de 8 Ohms. Cet appareil est couplé à un signal électrique audio d'une enceinte acoustique ou d'une alimentation acoustique. Cet appareil et procédé sont utilisables sur tous l es systèmes audio, audio-vidéo et tout mode de communication tel que téléphones , radio, ainsi que par le monde médical pour l'amélioration du confort auditif des malentendants.
