Abstract
(EN)
This earphone is provided with a speaker unit that generates sound waves, a sound conduit that is connected to the speaker unit, and an ear tip that is connected to the sound conduit and has at least one opening. The sound conduit includes: a sound hole, wherein sound waves generated by the speaker unit are inputted from a first opening, and are released from a second opening to which the ear tip is connected; and a vent that is provided independently of the sound hole, wherein some of the sound waves released from the second opening are inputted from a third opening, and released from a fourth opening. The second opening of the sound hole and the third opening of the vent are connected to the same opening in the ear tip.

La présente invention se rapporte à un écouteur comprenant : un module haut-parleur qui génère des ondes sonores ; un conduit sonore qui est connecté au module haut-parleur ; et un embout auditif qui est connecté au conduit sonore et qui a au moins une ouverture. Le conduit sonore comprend : un orifice sonore dans lequel des ondes sonores générées par le module haut-parleur sont amenées à entrer par une première ouverture, et sont amenées à sortir par une deuxième ouverture à laquelle est connecté l'embout auditif ; et un évent qui est placé indépendamment de l'orifice sonore, dans lequel une partie des ondes sonores qui sont amenées à sortir par la deuxième ouverture sont amenées à entrer par une troisième ouverture et sont amenées à sortir par une quatrième ouverture. La deuxième ouverture de l'orifice sonore et la troisième ouverture de l'évent sont connectées à la même ouverture dans l'embout auditif.
