Abstract

L'invention concerne un écouteur, qui s'adapte au conduit auditif tout en atténuant une sensation de pression sur le canal auditif, et qui peut être utilisé pendant une longue période.　L'écouteur comprend : un élément de bouchon ayant un trou d'insertion au centre de celui-ci dans lequel la pointe d'un conduit sonore est insérée ; et un clapet de non-retour disposé à une extrémité de l'élément de bouchon. L'élément de bouchon a une section creuse entre la paroi périphérique externe de l'élément de bouchon et la paroi périphérique interne entourant le trou d'insertion. Le clapet de non-retour permet un écoulement d'air de l'intérieur vers l'extérieur de la section creuse et supprime le flux d'air opposé.
