Abstract

Système acoustique à multiples transducteurs à rubans reproduisant le spectre des fréquences audibles.L'invention concerne un dispositif acoustique constitué de plusieurs transducteurs comportant des membranes rigides à rubans multiples munis de joues et nervures de renfort, se déplaçant en piston dans un champ magnétique exempt de tout obstacle, grâce à des organes de suspension à grand débattement permettant la reproduction des très basses fréquences. Un transducteur de structure similaire restitue le spectre médium-aigu. Tous les transducteurs sont intégrés dans un baffle plan conférant à l'ensemble une couverture complète du spectre des fréquences audibles sans les désagréments des systèmes équipés de transducteurs à membranes coniques.Acoustic system with multiple ribbon transducers reproducing the spectrum of audible frequencies. The invention relates to an acoustic device made up of several transducers comprising rigid membranes with multiple ribbon provided with reinforcing cheeks and ribs, moving in piston in a magnetic field free of any obstacle, thanks to suspension members with large clearance allowing the reproduction of very low frequencies. A transducer of similar structure restores the mid-acute spectrum. All the transducers are integrated in a flat cabinet giving the whole complete coverage of the audible frequency spectrum without the inconvenience of systems fitted with conical membrane transducers.
