Title (EN) PRESSURE EQUALIZATION IN EARPHONES
(FR) ÉGALISATION DE PRESSION DANS DES ÉCOUTEURS
Abstract:
(EN) An earphone includes an acoustic transducer and a housing that includes a first acoustic chamber acoustically coupled to a first side of the acoustic transducer and a second acoustical chamber acoustically coupled to a second side of the acoustic transducer. The housing further includes a port acoustically coupling the first acoustic chamber and the second acoustic chamber. Acoustic resistive material is positioned proximate the port.
(FR) Selon l'invention, un écouteur comprend un transducteur acoustique, et un boîtier comprenant une première chambre acoustique couplée acoustiquement à un premier côté du transducteur acoustique et une seconde chambre acoustique couplée acoustiquement à un second côté du transducteur acoustique. Le boîtier comprend en outre un orifice qui couple acoustiquement la première chambre acoustique et la seconde chambre acoustique. Un matériau à résistance acoustique est placé à proximité de l'orifice.
