CA 2408724

An acoustic transmission connection, e.g. for a headset (13), comprises a sound tube (2) through which speech signals can be transmitted from a first end (16) to a transducer, e.g. a microphone, in a housing or a housing part (3) of the headset. In the sound tube (2) and in the housing part (3), means are provided for acoustic impedance matching and possibly means for achieving acoustic directivity.

L'invention concerne une connexion d'émission acoustique, par exemple pour un casque (13), comprenant un tube son (2) à travers lequel des signaux vocaux peuvent passer d'une première extrémité (16) vers un transducteur, par exemple un microphone, disposé dans un logement ou dans une partie de logement (3) du casque. On a placé dans le tube son (2) et dans la partie logement (3) des moyens permettant une adaptation d'impédance acoustique et si possible des moyens de réalisation de directivité acoustique.
