Abstract

La présente invention concerne un dispositif de haut-parleur. Le dispositif comprend un boîtier, une base et une partie de liaison élastique. L'un du boîtier ou de la base comporte un trou traversant, une première surface incurvée étant disposée autour de la périphérie extérieure du trou traversant, et l'autre du boîtier ou de la base ayant une partie de butée qui coopère avec la première surface incurvée. La partie de liaison élastique passe à travers le trou traversant et relie la base au boîtier. Le diamètre du trou traversant est supérieur au diamètre externe de la partie de liaison élastique. La partie de liaison élastique est configurée pour former une force élastique dirigée de la base vers le boîtier pour amener la partie de butée à venir en butée contre la première surface incurvée, et la partie de butée peut coulisser le long de la première surface incurvée. Un problème technique à résoudre par la présente invention est celui de l'angle fixe d'un dispositif de haut-parleur existant qui conduit à l'impossibilité de modifier la direction de réglage en fonction de différentes positions de montage et qui conduit en outre à un effet sonore médiocre. Une utilisation de la présente invention consiste à modifier la direction de réglage du haut-parleur.
