Abstract

La présente invention concerne un appareil d'écoute, un support et un haut-parleur. L'appareil d'écoute comprend : un boîtier ; le haut-parleur, qui est placé à l'intérieur du boîtier ; le support, qui est respectivement relié au boîtier et au haut-parleur ; et un cadre d'isolation, qui est placé du côté opposé à une surface de production de son du haut-parleur. Le support est entouré par un trou traversant qui est en communication avec la surface de génération de son et un trou de sortie de son du boîtier. Une paroi de la cavité sonore arrière de l'appareil d'écoute comprend le cadre d'isolation et une paroi latérale extérieure du support à l'écart du trou de passage. De cette manière, la cavité sonore arrière peut être agrandie du côté de la surface de production du son proche de l'orifice de sortie du son, de sorte que le volume de la cavité sonore arrière est augmenté, ce qui facilite l'amélioration de la qualité du son de l'appareil d'écoute.
