Abstract

The invention relates to a loudspeaker module for a portable device, comprising a near field communication device (NFC) and its antenna. The loudspeaker (14) comprises a main coil (L) connected so as to receive an external audio signal through an excitation contact (A1), and the NFC device comprises a reception circuit (Tx) configured to extract data from a signal applied to the excitation contact (A1) of the main coil of the loudspeaker; and an emission circuit (Rx) configured to emit data in the sound emitted by the loudspeaker.
