Abstract

L'invention concerne un vibrateur à conduction osseuse à réduction du bruit, qui comprend un boîtier cylindrique (2) et une pièce élastique (4) disposée à proximité du fond du boîtier (2). Un bossage (6) faisant saillie vers l'intérieur dans une direction radiale est disposé sur le fond du boîtier (2). La pièce élastique (4) est disposée sur le bossage (6). La pièce élastique (4) est une plaque métallique mince, un trou traversant (8) est ménagé sur la pièce élastique (4), et un support cupuliforme (10) est disposé sur un côté de la pièce élastique (4) en regard de l'ouverture du boîtier (2). Pour fixer davantage la pièce élastique (4) et le support (10), la pièce élastique (4) est soudée par points à la partie inférieure du support (10). Un aimant (12) est disposé sur le fond du support (10). En outre, une cavité de réception (14) destiné à recevoir l'aimant (12) est disposée au centre du fond du support (10). L'aimant (12) est fixé de manière stable dans le support (10). Une carte de circuit imprimé (16) et un couvercle supérieur (18) agencé côté extérieur de la carte de circuit imprimé (16) sont disposés au niveau de l'ouverture du boîtier (2). Une surface d'extrémité supérieure du couvercle supérieur (18) est alignée avec une surface d'extrémité supérieure du boîtier (2). Le couvercle supérieur (18) est respectivement collé et fixé sur le boîtier (2) et la carte de circuit imprimé (16) par utilisation d'un adhésif résistant à l'eau. Un cadre de support annulaire (20) est soutenu entre la pièce élastique (4) et la carte de circuit imprimé (16). Une bobine (22) est disposée sur un côté de la carte de circuit imprimé (16) en regard du support (10). La bobine (22) est électriquement connectée à la carte de circuit imprimé (16). La bobine (22) et l'aimant (12) sont agencés concentriques, et la bobine (22) est au moins partiellement enroulée autour de l'aimant (12). La structure interne du vibrateur est installée de manière stable et fixe, aucun bruit n'est fait et de bons effets stéréo sont produits, et le volume du vibrateur entier est petit, de sorte que le vibreur peut être agencé dans le corps principal d'un écouteur, et en conséquence une vibration externe est réduite et une réduction du bruit est obtenue.
