Abstract

Ecouteur pour casque audio comprenant un système d’équilibrage de pression interne Ecouteur (14) pour casque audio, comprenant : une coque (22), un coussinet (24), et un haut-parleur (26). L’écouteur définit : - une première chambre (34) à une pression P1, s’étendant depuis la membrane (32) du haut-parleur vers l’avant, - une deuxième chambre (36) à une pression P2, s’étendant depuis la membrane vers l’arrière à l’intérieur du haut-parleur, - une troisième chambre (38) à une pression P3, délimitée par la coque et le haut-parleur, - un premier orifice (40) de communication entre la troisième chambre et l’atmosphère environnante (42), un deuxième orifice (44) de communication entre la troisième chambre et la deuxième chambre, et un système d’équilibrage de pression (46) reliant la première chambre à la deuxième chambre ou à la troisième chambre, configuré pour être passant ou non passant en fonction d’une différence de pression entre les chambres.
