Abstract

L'invention concerne un casque à fonction égalisatrice de pression. Le casque comprend un logement avant de casque et un logement arrière de casque, des manchons d'oreilles étant disposés du côté extérieur du logement avant de casque ; un trou acoustique avant est formé dans le logement avant de casque ; et des dispositifs de résistance acoustique de type intercalaire sont agencés à la jonction des bords des manchons d'oreille et du logement avant de casque et à la jonction des bords du logement avant de casque et du logement arrière de casque respectivement. Selon le casque à fonction égalisatrice de pression selon la présente invention, la fuite d'énergie à basse fréquence peut être réduite quand la pression d'une cavité acoustique avant et d'une cavité acoustique arrière du casque est libérée, de sorte que le casque est confortable à porter sans sensation de pression, et la qualité acoustique est équilibrée.
