Abstract

La présente invention concerne un haut-parleur. Le haut-parleur comprend un boîtier, et un système de résonance et un système de circuit magnétique logés dans le boîtier. Le système de résonance comprend un encadrement, un cône acoustique, une carcasse de bobine et un atténuateur. Le cône acoustique est un mécanisme en forme d'arc, l'encadrement est fixé à un bord extérieur du cône acoustique, et une partie d'extension vers le bas est disposée sur la position du bord extérieur au niveau de laquelle le cône acoustique est fixé à l'encadrement. L'atténuateur a une structure annulaire, un côté extérieur de l'atténuateur ayant la structure annulaire est fixé au boîtier, et un côté intérieur de l'atténuateur ayant la structure annulaire est fixé à une extrémité inférieure de la partie d'extension. L'atténuateur du haut-parleur dans la présente invention est situé sur un côté extérieur du cône acoustique et n'occupe pas un espace de résonance du cône acoustique, augmentant ainsi efficacement l'espace de résonance, et améliorant également les performances du produit tout en réduisant la hauteur du haut-parleur, et permettant en outre un design mince du haut-parleur. Le haut-parleur de la présente invention a comme avantages des performances acoustiques favorables et un design mince.
