Abstract

La présente invention concerne le domaine technique des dispositifs de conduction osseuse, et en particulier, un vibrateur pour conduction osseuse et un dispositif d'écoute à conduction osseuse. Le vibrateur pour conduction osseuse comprend un fer en forme de U, un aimant, une bobine acoustique, une feuille de conduction et un amortisseur électroconducteur. Un support est disposé sur la paroi latérale externe du fer en forme de U. Un coussinet est disposé sur le support. L'amortisseur électroconducteur est relié au support et connecté électriquement au coussinet. La bobine acoustique est fixée sur l'amortisseur électroconducteur et connectée électriquement à l'amortisseur électroconducteur. La feuille de conduction est connectée à la bobine acoustique et située à l'extérieur de l'amortisseur électroconducteur. Dans la présente invention, l'utilisation d'une approche d'électrification d'un fil de bobine acoustique avec une alimentation électrique externe évite la rupture du fil de bobine acoustique provoquée par le frottement entre le fil de bobine acoustique et des composants dans le vibrateur pour conduction osseuse en raison d'une vibration, et améliore la stabilité des produits et la qualité du dispositif vibrant à conduction osseuse ; en outre, lorsqu'il vibre, la bobine acoustique entraîne l'amortisseur électroconducteur à vibrer, de telle sorte que le support et l'amortisseur électroconducteur vibrent de manière synchrone, produisant ainsi un bon effet de basse.
