Title
(EN) SPEAKER SYSTEM
(FR) SYSTEME DE HAUT-PARLEUR
Abstract
(EN)
A speaker system (10) includes a speaker unit (14) and a horn (12) having an end portion to which the speaker unit (14) is attached. A first membrane (24) is attached to an end portion of the horn (12) to block the end portion. A second membrane (26) is installed to the other end portion of the horn (12). A closed room (30) is provided by way of the first membrane (24) and second membrane (26). The room (30) is filled with a gas which is heavier than air.
(FR)
Selon cette invention, un système de haut-parleur (10) comprend une unité haut-parleur (14) et un cornet (12) possédant une partie d'extrémité à laquelle est fixée l'unité haut-parleur (14). Une première membrane (24) est fixée à une partie terminale du cornet (12) de manière à bloquer la partie terminale. Une deuxième membrane (26) est installée à l'autre partie terminale du cornet (12). Une enceinte close (30) est aménagée devant la première (24) et la deuxième (26) membranes. Cette enceinte (30) est remplie d'un gaz plus lourd que l'air.
