Abstract

La présente invention concerne un boîtier de haut-parleur et un dispositif terminal électronique. La boîte de haut-parleur comprend un boîtier ayant un espace de réception et une unité de génération de son reçue dans l'espace de réception. Le boîtier comprend un boîtier supérieur ayant une première ouverture, un boîtier inférieur ayant une seconde ouverture, une première plaque d'acier fixée sur le boîtier supérieur et recouvrant de manière correspondante le boîtier supérieur, et une seconde plaque d'acier fixée au boîtier inférieur et recouvrant de manière correspondante le boîtier inférieur. Le boîtier de haut-parleur comprend en outre une languette élastique conductrice fixée à la surface extérieure du boîtier, une extrémité de la languette élastique conductrice étant reliée à la première plaque d'acier, et l'autre extrémité de la languette élastique conductrice étant reliée à la seconde plaque d'acier. La languette élastique conductrice est reliée et conduite à la première plaque d'acier au niveau du boîtier supérieur et de la seconde plaque d'acier au niveau du boîtier inférieur, respectivement. La fonction de mise à la masse simultanée de la première plaque d'acier et de la seconde plaque d'acier peut être mise en œuvre simplement par mise à la terre de la languette élastique conductrice ou de la première plaque d'acier ou de la seconde plaque d'acier. La présente invention optimise efficacement une solution de conception de mise à la masse d'une unité entière, économise un espace de conception de l'unité entière, et est ainsi plus fiable.
