Abstract

Le modèle d'utilité concerne un écouteur bouton, comprenant un boîtier de casque, un boîtier, une carte de circuit imprimé, un haut-parleur et un élément magnétique. Le boîtier a un espace de réception à l'intérieur de celui-ci; la carte de circuit imprimé et le haut-parleur sont tous deux disposés dans l'espace de réception; le boîtier est au moins partiellement emmanché avec le boîtier de casque; l'élément magnétique est disposé entre le boîtier de casque d'écoute et le boîtier. En disposant l'élément magnétique entre le boîtier et le boîtier de casque, par exemple, dans une rainure de réception utilisée pour recevoir l'élément magnétique et formé par dénervation vers l'intérieur du côté du boîtier recouvert par le boîtier de casque, l'élément magnétique est placé à l'extérieur du boîtier, de telle sorte que l'élément magnétique n'est pas bloqué depuis l'extérieur par le boîtier, et ainsi, la force magnétique est augmentée lorsque l'écouteur bouton est attiré magnétiquement, rendant le positionnement plus stable. L'écouteur bouton fourni par le modèle d'utilité a une structure simple et une grande facilité de mise en œuvre, et est facile à mettre en œuvre et approprié pour la promotion et l'application.
