Abstract

Le présent modèle d'utilité concerne des écouteurs Bluetooth, comportant un écouteur primaire et un écouteur secondaire. L'écouteur primaire et l'écouteur secondaire peuvent être interconnectés sans fil via Bluetooth en l'absence de fil de connexion. Lorsqu'un environnement ne permet pas à un utilisateur de porter les écouteurs sur les deux oreilles, l'utilisateur peut ne porter que l'écouteur primaire, et l'écouteur primaire à lui seul permet à l'utilisateur de communiquer lors d'un appel ou d'écouter des contenus audio. Lorsque l'utilisateur souhaite entendre des sons stéréo sur deux voies et lorsqu'un environnement permet à l'utilisateur de porter les écouteurs sur les deux oreilles, l'utilisateur peut porter les écouteurs primaire et secondaire en même temps. Dans ce cas, l'écouteur primaire transmet à l'écouteur secondaire un signal de voie sonore compris dans un contenu audio A2DP reçu, de façon à réaliser la reproduction de sons stéréo.
