Abstract

Enceinte acoustique simplifiée Enceinte acoustique (1) comprenant : - un caisson (5) comprenant une paroi (42) visible au moins en partie depuis l’extérieur de l’enceinte acoustique, et une partie de fixation (44) fixée sur la paroi visible, - au moins un haut-parleur (10) fixé sur la partie de fixation, le haut-parleur définissant un axe (D) et comprenant un circuit magnétique (18), et un équipage mobile (22) monté mobile axialement par rapport au circuit magnétique autour d’une position d’équilibre, l’équipage mobile comportant une membrane (32) adaptée pour émettre des ondes sonores, la membrane définissant un côté avant du haut-parleur, - un premier joint de suspension (14) comportant une première extrémité (50) radialement intérieure fixée sur l’équipage mobile, et - un deuxième joint de suspension (16) comportant une première extrémité (56) fixée sur l’équipage mobile, l’équipage mobile, le caisson et le premier joint de suspension définissant au moins en partie un volume intérieur (26) d’air confiné. Le premier joint de suspension comprend une deuxième extrémité (52) radialement extérieure fixée sur ladite paroi visible. Le deuxième joint de suspension comprend une deuxième extrémité (58) fixée sur le caisson. Figure pour l'abrégé : Figure 1Simplified acoustic enclosure Acoustic enclosure (1) comprising: - a box (5) comprising a wall (42) visible at least in part from the exterior of the acoustic enclosure, and a fixing part (44) fixed to the visible wall , - at least one loudspeaker (10) fixed to the fixing part, the loudspeaker defining an axis (D) and comprising a magnetic circuit (18), and a mobile assembly (22) mounted so as to be able to move axially with respect to the magnetic circuit around an equilibrium position, the movable assembly comprising a membrane (32) adapted to emit sound waves, the membrane defining a front side of the loudspeaker, - a first suspension joint (14) comprising a radially inner first end (50) fixed to the moving assembly, and - a second suspension joint (16) comprising a first end (56) fixed to the moving assembly, the moving assembly, the casing and the first suspension joint suspension defining at least in part a volume i interior (26) of confined air. The first suspension joint comprises a second radially outer end (52) fixed to said visible wall. The second suspension joint includes a second end (58) attached to the box.
