Abstract

L'invention concerne un procédé de lecture de données audio et un terminal mobile à double écran. Le terminal mobile à double écran comprend au moins deux circuits de lecture audio. Le procédé consiste à : identifier un écran cible, l'écran cible affichant des données d'affichage d'une application cible, et l'écran cible étant l'un des deux écrans du terminal mobile à double écran (S101) ; rechercher un circuit de lecture audio cible correspondant à l'écran cible, le circuit de lecture audio cible étant l'un des deux circuits de lecture audio (S102) ; et lire des données audio au moyen du circuit de lecture audio cible (S103). Dans la présente invention, lorsque des données d'affichage d'une application sont affichées sur un écran, des données audio de l'application sont lues par un circuit de lecture audio correspondant à l'écran, ce qui permet d'éviter un méli-mélo de sons et d'obtenir un meilleur effet de lecture sonore.
