Abstract

La présente invention concerne un procédé de sortie audio, qui est appliqué à un dispositif électronique pliable. Le dispositif électronique pliable comprend une unité d'affichage, une unité de détection, une unité de sortie audio, et une unité de traitement ; l'unité d'affichage comprend un premier sous-écran d'affichage et un second sous-écran d'affichage, et l'unité de sortie audio comprend une première interface audio et une seconde interface audio qui sont disposées sur le premier sous-écran d'affichage et le second sous-écran d'affichage respectivement. Le procédé de sortie audio comprend les étapes suivantes consistant à : détecter des informations de position relative du premier sous-écran d'affichage et du second sous-écran d'affichage au moyen de l'unité de détection ; acquérir les informations de position relative détectées par l'unité de détection afin de déterminer l'état de position relative du premier sous-écran d'affichage et du second sous-écran d'affichage ; selon l'état de position relative du premier sous-écran d'affichage et du second sous-écran d'affichage, commander l'unité de sortie audio pour délivrer en sortie les mêmes signaux audio identiques ou différents au moyen de la première interface audio et de la seconde interface audio. La présente invention concerne également un dispositif électronique portable.
