Abstract

L'invention concerne un système écouteur multifonction pour activités sportives, comprenant : un premier dispositif qui est conçu pour être porté dans une oreille d'un utilisateur et qui possède une première unité de communication de données et un premier haut-parleur, et un deuxième dispositif qui est conçu pour être porté dans l'autre oreille d'un utilisateur et qui possède une deuxième unité de communication de données et un deuxième haut-parleur. Au moins l'un des premier et deuxième dispositifs possède une unité de détection et une unité de traitement de données. L'unité de traitement de données est conçue pour générer des données de puissance en se basant sur des données de mesure acquises par l'unité de détection. Le premier dispositif possède en outre une unité de traitement de signal qui est conçue pour générer un signal audio binaural en se basant sur les données de puissance. Le signal audio binaural possède une première partie de signal destinée à être délivrée par le premier haut-parleur et une deuxième partie de signal destinée à être délivrée par le deuxième haut-parleur. La première unité de communication de données est conçue pour transmettre la deuxième partie du signal audio binaural à la deuxième unité de communication de données. L'invention concerne en outre un procédé.
