Abstract

La présente invention concerne un procédé et un appareil de lecture audio, un dispositif électronique et un support lisible par ordinateur, se rapportant au domaine technique des communications. Le procédé comprend les étapes consistant à : lorsque deux dispositifs de lecture audio sans fil lisent différentes données audio pour réaliser une lecture mixte, déterminer si chacun des dispositifs de lecture audio sans fil est dans un état prédéfini ; prendre le dispositif de lecture audio sans fil dans l'état prédéfini en tant que premier dispositif de lecture audio sans fil, et prendre les données audio lues par celui-ci en tant que premières données audio ; prendre le dispositif de lecture audio sans fil non dans l'état prédéfini en tant que second dispositif de lecture audio sans fil, et prendre les données audio lues par celui-ci en tant que secondes données audio ; et commander le second dispositif de lecture audio sans fil pour lire simultanément les premières données audio et les secondes données audio de façon à réaliser une lecture mixte. Par conséquent, même si un utilisateur abandonne l'utilisation d'un des dispositifs de lecture audio sans fil pour écouter les données audio, l'autre dispositif de lecture audio sans fil peut également lire simultanément les deux éléments de données audio pour obtenir l'effet de lecture mixte.
