Title (EN) ELECTRODYNAMIC LOUDSPEAKER HAVING A CENTRED SUSPENSION JOINT
(FR) HAUT-PARLEUR ÉLECTRODYNAMIQUE AVEC JOINT DE SUSPENSION CENTRÉ
Abstract:
(EN) The invention relates to an electrodynamic loudspeaker having: - a frame (17), - an assembly (23) that is movable in translation with respect to the frame along an axis (D) of the loudspeaker about an equilibrium position that is taken up when the loudspeaker is at rest, the assembly having at least one diaphragm (29) configured to emit sound waves, and - at least one suspension joint (25) for the assembly. The joint forms a loop around the assembly and comprises: - a first end (39A) secured to the assembly, - a second end (41A) secured to the frame, and - a main part (43) that connects the first end and the second end and ensures axial flexibility of the joint. The first end or the second end comprises a distal part with respect to the main part, and a proximal part, the distal part being more radially compressible than the proximal part, and being compressed radially between the proximal part and an end stop of the assembly or of the frame.
(FR) Haut-parleur électrodynamique comportant : - un châssis (17), - un ensemble (23) mobile par rapport au châssis en translation selon un axe (D) du haut-parleur autour d'une position d'équilibre occupée lorsque le haut-parleur est au repos, l'ensemble comportant au moins une membrane (29) configurée pour émettre des ondes sonores, et - au moins un joint (25) de suspension de l'ensemble. Le joint forme une boucle autour de l'ensemble, et comprend : - une première extrémité (39A) fixée sur l'ensemble, - une deuxième extrémité (41A) fixée sur le châssis, et - une partie principale (43) reliant la première extrémité et la deuxième extrémité et assurant une souplesse axiale du joint. La première extrémité ou la deuxième extrémité comprend une partie distale par rapport la partie principale, et une partie proximale, la partie distale étant plus compressible radialement que la partie proximale, et étant comprimée radialement entre la partie proximale et une butée de l'ensemble ou du châssis.
