Abstract

L'invention est relative à un module haut-parleur pour dispositif portable, comprenant un dispositif de communication en champ proche (NFC) et son antenne. Le haut-parleur (14) comprend une bobine principale (L) connectée pour recevoir un signal audio externe par un contact d'excitation (A1), et le dispositif NFC comprend un circuit de réception (Tx) configuré pour extraire des données d'un signal appliqué sur le contact d'excitation (A1) de la bobine principale du haut-parleur; et un circuit d'émission (Rx) configuré pour émettre des données dans le son émis par le haut-parleur.
