Abstract

Le présent modèle d'utilité concerne le domaine technique des écouteurs de type serre-tête et concerne une structure à engrenages multiples d'un bras de support d'écouteur de type serre-tête. Un second coussin élastique et un premier coussin élastique sont installés dans deux premières rainures d'assemblage au niveau d'une partie supérieure d'un revêtement extérieur de serre-tête. Une ligne de transmission audio pénètre dans un second trou traversant, une rainure de limitation et une partie interne d'un arbre rotatif. Une extrémité d'un arbre en acier pénètre dans un premier trou traversant et une première rainure d'assemblage, et en même temps, l'arbre rotatif s'ajuste étroitement avec le second coussin élastique et le premier coussin élastique. L'arbre en acier pénètre dans un revêtement intérieur de serre-tête pour presser les côtés extérieurs de l'arbre rotatif sur deux côtés, et est fixé sur le couvercle extérieur du serre-tête au moyen d'un couvercle d'extrémité de l'arbre rotatif, de sorte que le second coussin élastique et le premier coussin élastique sur les côtés gauche et droit se déforment et produisent un amortissement et une sensation d'engrenage, et tournent à différents angles d'ouverture et de fermeture pour obtenir l'ouverture et la fermeture de l'arbre rotatif. Dans un espace limité, une sensation de pliage à deux vitesses et une sensation d'amortissement de rotation pendant le pliage sont obtenues, ce qui permet d'obtenir une fonction de pliage à deux vitesses et d'augmenter l'amortissement pour améliorer l'expérience d'utilisateur.
