Abstract

L'invention porte sur un mécanisme de montage de lecteur audio qui est capable d'empêcher l'endommagement d'un connecteur lorsqu'un utilisateur attache le lecteur audio au connecteur ou l'en détache. Une poignée (16) faite d'un élément métallique en forme de tige s'étend vers le haut à partir des composants latéraux (101) d'un boîtier (11) de manière à prendre en sandwich les côtés droit et gauche d'un siège (31), et fléchit verticalement à des emplacements situés à une distance prédéterminée du siège (31) afin de devenir parallèle à la surface supérieure du siège (31). La poignée (16) s'étend vers le haut au même angle d'inclinaison que celle du connecteur (18), à l'arrière de l'emplacement où le connecteur (18) est installé. Ainsi, en appuyant le lecteur audio portable contre cette poignée (16), le lecteur audio portable peut être monté au même angle d'inclinaison que celle du connecteur (18), empêchant le lecteur audio portable de s'incliner vers l'arrière.
