Abstract

Le présent modèle d'utilité fournit un haut-parleur Bluetooth comprenant un corps de haut-parleur. Le corps de haut-parleur comprend une puce de commande disposée dans le corps de haut-parleur ainsi qu'un module haute fréquence d'émission numérique connecté à la puce de commande. L'invention concerne également un système de partage basé sur un haut-parleur Bluetooth, comprenant au moins deux haut-parleurs Bluetooth qui sont tels que le haut-parleur Bluetooth mentionné ci-dessus, et comprenant en outre un dispositif d'entrée externe. Une unité d'émetteur-récepteur Bluetooth de l'un des haut-parleurs Bluetooth est en connexion de signal avec le dispositif d'entrée externe et délivre un signal à une unité de microcontrôleur ; l'unité de microcontrôleur délivre le signal au module haute fréquence d'émission numérique du haut-parleur Bluetooth ; puis le module haute fréquence d'émission numérique du haut-parleur Bluetooth délivre le signal au module haute fréquence d'émission numérique du reste des haut-parleurs Bluetooth. Le haut-parleur Bluetooth permet à plusieurs personnes de partager des informations audio (telles que de la musique) et assure la qualité sonore des informations audio partagées (telles que la musique).
