Abstract

L'invention concerne un dispositif de lecture audio (100) et son utilisation et un procédé de mise à jour de données associé. Le dispositif de lecture audio (100) comprend : un ensemble de commande (110), un ensemble mémoire (120), un ensemble de déclenchement (130) et un ensemble de communication (140), l'ensemble mémoire (120) étant configuré pour mémoriser une liste de lecture de fichiers audio locaux comprenant au moins un fichier audio ; l'ensemble de déclenchement (130) étant configuré pour envoyer un signal de déclenchement à l'ensemble de commande (110) lorsqu'un environnement actuel déclenche une condition de lecture prédéfinie d'un dispositif de lecture audio actuel (100) ; l'ensemble de commande (110) étant configuré pour appeler, selon une première stratégie de lecture, un fichier audio pré-mémorisé correspondant de la liste de lecture audio locale de l'ensemble mémoire et le lire (120) ; l'ensemble de commande (110) étant en outre configuré pour collecter des données de lecture et les téléverser vers un système de commande central prédéfini pour effectuer un réglage de stratégie ; et l'ensemble de communication (140) étant configuré pour recevoir une instruction de mise à jour provenant du système de commande central et mettre à jour les données. Le dispositif de lecture audio (100) est géré à distance, de façon à s'adapter à différents environnements et exigences de scénario, et à pousser des informations requises et notables à un utilisateur.
