Abstract

Selon cette invention, un écouteur exempt de bruit impulsif et servant à la protection contre la surdité de conduction comprend un boîtier d'écouteur (40) et un haut-parleur monté (50) dans la chambre acoustique (43) dudit boîtier. Une extrémité avant du boîtier d'écouteur possède un bouche-oreille (41) conçu pour être accroché entre le tragus et l'antitragus de l'oreille externe, son extrémité arrière étant munie d'un capuchon (42) avec une chambre creuse enroulée (43). Un haut-parleur est placé à l'intérieur de la chambre acoustique creuse du capuchon, avec des trous acoustiques (44) distribués sur le pourtour. Une extrémité de sortie acoustique du haut-parleur doit être placée face au capuchon et du côté opposé du bouche-oreille. Un fil conducteur (60), connecté au fond du boîtier d'écouteur, sert à alimenter le haut-parleur en courant électrique.
