Abstract

Selon un mode de réalisation de la présente invention, un appareil électronique comprend un écran, un haut-parleur, des bornes, et des moyens de réglage sonore. Les bornes servent à délivrer en sortie des signaux d'image et des signaux sonores. Elles sont connectées à un dispositif d'affichage externe. Les moyens de réglage sonore exécutent un réglage tel que, lorsqu'une première fenêtre est affichée sur un écran de l'affichage et une seconde fenêtre est affichée sur un écran du dispositif d'affichage externe, des premiers signaux sonores relatifs à la première fenêtre sont transmis au haut-parleur et des seconds signaux sonores relatifs à la seconde fenêtre sont transmis aux bornes.
