Title (EN) COMMUNICATION TERMINAL DEVICE
(FR) DISPOSITIF DE COMMUNICATION POUR UN TERMINAL
Abstract:
(EN) A communication terminal device carries out data processing based on key or touch panel operations and provides a telephone conversation function. When a key is actuated, a key input confirmation sound is generated. When data input is performed on the touch panel with a pen, a pen impact sound caused by striking the touch panel with the pen and a pen frictional sound caused by rubbing the touch panel with the pen are generated. In the telephone conversation mode, the key input confirmation sound, the pen impact sound, and the pen frictional sound are picked up as noises by the microphone. Upon detecting such noises, the communication terminal device generates noise and cancelling signals corresponding to the respective noises and cancels each noise from a voice signal input form the microphone. Thus, a voice signal free from noises is transmitted.
(FR) Un terminal de communication permet un traitement de données à l'aide d'un panneau à contact ou de touches et il permet également une conversation téléphonique. Quand une touche est activée, le dispositif génère un son de confirmation d'entrée. Lorsque l'utilisateur entre des données par le panneau à contact avec un stylo, et se produit un son d'impact du stylo, provoqué par le stylo venant en contact avec le panneau et un son de frottement provoqué par le frottement du stylo sur le panneau. Dans un mode conversation téléphonique, le son de confirmation d'entrée par les touches, le son d'impact du stylo et le son de frottement du stylo sont détectés par le microphone comme bruits. A la détection de ces brits, le terminal génère un signal de suppression de bruit correspondant au bruit respectif et supprime chaque bruit du signal vocal du microphone. Ainsi, on peut transmettre un signal vocal exempt de bruits.
