Abstract

La présente invention concerne un haut-parleur plat qui peut être monté n'importe où, par exemple à la surface d'un mur ou d'un sol, au moyen d'un aimant de fixation monté sur le haut-parleur. Ce haut-parleur offre l'effet d'un grand haut-parleur, mais sous forme d'un petit haut-parleur, il traite des signaux sonores de diverses bandes de fréquences étant donné que la surface du mur ou du sol à laquelle le haut-parleur plat est fixé sert de membrane pour amplifier des sons, il améliore les courbes de réponse en fréquence étant donné qu'un film de vibration composé d'un stratifié de carbone ou de verre est fixé au haut-parleur, et il reçoit des signaux provenant de moyens de génération de source sonore, tels que des lecteurs de CD, des lecteurs MP3, etc, par le biais d'une communication radio Bluetooth.
