Abstract
(EN)
An earpiece device includes a microphone and a speaker having a common acoustic channel to reduce complexity and minimize components in an ear canal region. The earpiece device also includes a logic circuit operatively connected into an earpiece, where the microphone is configured to sample an acoustic signal traveling from either end of an acoustic channel. The earpiece device further includes a selective attenuation mechanism for varying the acoustic energy from one end of the acoustic channel or combining the acoustic energies in a controlled ratio from both ends of the acoustic channel before reaching the microphone.
(FR)
L'invention concerne une oreillette comprenant un microphone et un haut-parleur qui présentent un canal acoustique commun de manière à réduire la complexité et à ramener à un minimum des composants reçus dans une région de canal auriculaire. L'oreillette comprend également un circuit logique relié opérationnel dans une oreillette, le microphone étant conçu pour échantillonner un signal acoustique se déplaçant à partir de l'une ou l'autre des extrémités d'un canal acoustique. L'oreillette comprend en outre un mécanisme d'atténuation sélective permettant de faire varier l'énergie acoustique d'une extrémité du canal acoustique ou de combiner les énergies acoustiques en un rapport contrôlé à partir des deux extrémités du canal acoustique avant que l'énergie acoustique n'atteigne le microphone.
