Abstract

La présente invention concerne un boîtier de protection destiné à être installé sur un dispositif électronique. L'étui de protection comprend au moins un cadre latéral, dans lequel le cadre latéral est configuré pour au moins venir en butée contre le dispositif électronique à l'endroit où un trou de sortie de son est prévu ; le cadre latéral est pourvu d'un canal de son qui est configuré pour être en communication avec le trou de sortie de son du dispositif électronique ; et le cadre latéral est pourvu d'au moins deux groupes de trous de son, qui sont tous deux en communication avec le canal de son, différents groupes de trous de son étant respectivement situés dans différentes surfaces du cadre latéral. Le son produit par le dispositif électronique peut être émis à partir d'au moins les trous sonores dans différentes positions, de sorte que lorsque le dispositif électronique fonctionne, il est généralement impossible de bloquer tous les trous sonores dans différentes positions, et donc, l'expérience de l'utilisateur n'est pas affectée. En outre, en prévoyant respectivement des trous sonores dans différentes surfaces, le son qui est initialement émis dans une direction peut être dispersé et émis dans différentes directions au moyen des trous sonores dans différentes directions, améliorant ainsi l'effet stéréophonique d'ambiance du son.
