Abstract

Haut-parleur comprenant une membrane montée réversiblement, et enceinte acoustique intégrant un tel haut-parleur Haut-parleur (16) comprenant : - un circuit magnétique (26) définissant au moins un entrefer (28), - un équipage mobile (30) comprenant un porte-bobine (36), une bobine (38) située dans l’entrefer, une membrane (40) adaptée pour émettre des ondes sonores, et un système de liaison (42) reliant la membrane et le porte-bobine. La membrane est mobile réversiblement par rapport au système de liaison entre une position montée, dans laquelle la membrane est solidaire du système de liaison, et une position démontée, dans laquelle la membrane est à l’écart du système de liaison. Dans la position montée, la membrane forme un écran entre l’extérieur du haut-parleur et le circuit magnétique. Procédé correspondant, et enceinte acoustique intégrant un tel haut-parleur. Figure pour l'abrégé : Figure 2Loudspeaker comprising a reversibly mounted membrane, and acoustic enclosure integrating such a loudspeaker Loudspeaker (16) comprising: - a magnetic circuit (26) defining at least one air gap (28), - a mobile assembly (30) comprising a coil holder (36), a coil (38) located in the air gap, a membrane (40) adapted to emit sound waves, and a connection system (42) connecting the membrane and the coil holder. The membrane is reversibly movable relative to the connection system between an mounted position, in which the membrane is integral with the connection system, and a disassembled position, in which the membrane is away from the connection system. In the mounted position, the membrane forms a screen between the exterior of the speaker and the magnetic circuit. Corresponding method, and acoustic enclosure integrating such a loudspeaker.
