Abstract

La présente invention concerne un téléphone mains-libres comportant un combiné (1) séparable en première et seconde parties (2, 3) et un serre-tête séparé (17) conçu pour recevoir les première et seconde parties, de manière à permettre l'utilisation mains-libres du téléphone. Lorsque les première et seconde parties du combiné sont reliées ensemble, le téléphone peut être utilisé de manière conventionnelle. Dans une variante, lorsque les première et seconde parties sont séparées l'une de l'autre et attachées au serre-tête et qu'un microphone sur tige (18, 19) est employé, le téléphone peut être utilisé en mode mains-libres.
