Abstract

L'invention concerne un téléphone sans fil destiné à être utilisé comme téléphone par fil ordinaire, tout en offrant l'ensemble des avantages d'un téléphone sans fil ordinaire. Le téléphone considéré comporte une partie mobile dont l'unité principale (8) est reliée à un combiné du type émetteur-récepteur (9) via un cordon spiralé (10). En outre, le téléphone comporte une partie fixe équipée d'un circuit de signal de sonnerie, d'un circuit de transmission sans fil (42), d'un circuit de réception sans fil (43), et d'un dispositif de contrôle de poste téléphonique. La partie mobile comporte un circuit émetteur-récepteur sans fil, un circuit de commande, un circuit de détection de récepteur (22), un circuit de microphone (18), une batterie (7), un cordon spiralé (10), un microphone (26), et un haut-parleur (11). Par rapport aux avantages que présente un téléphone sans fil classique, les utilisateurs jugent encore qu'il est parfois difficile de localiser l'endroit ou le combiné (9) a été reposé après la dernière utilisation et qu'il est parfois peu pratique de placer le combiné (9) sur une table en raison des lignes du téléphone (1) et de l'alimentation en énergie (45).
