Claims (6)

  1. Système d'aide auditive (100) ayant une unité de communication (120) pour la transmission et la réception de signaux par voie inductive, ladite unité de communication (120) comprenant :
    une unité active (210) adaptée pour faire passer une antenne inductive (220) dans un état transmission au moyen d'une première inductance (255) couplée à ladite antenne (220) ;
    une unité de détermination de fréquence (215) couplée à ladite antenne (220) au moyen d'une deuxième inductance (256) et adaptée pour commander la fréquence de transmission dans ledit état transmission et pour envoyer les signaux reçus à un récepteur frontal (225) dans un état réception ; et caractérisé en ce que l'unité active (210) comprend une troisième inductance (254) couplée à ladite antenne (220) et adaptée pour envoyer à l'unité active (210) un retour d'informations provenant de l'unité de détermination de fréquence (215).
  2. Aide auditive selon la revendication 1, dans laquelle ladite unité de détermination de fréquence (215) comprend ladite deuxième inductance (256) et un condensateur (257).
  3. Aide auditive selon la revendication 1, dans laquelle ladite antenne (220) comprend un élément ferromagnétique pour le couplage desdites première et deuxième inductances (255, 256).
  4. Aide auditive selon l'une quelconque des revendications 1 à 3, dans laquelle ladite unité active est adaptée pour faire passer ladite antenne inductive (220) à l'état transmission au moyen d'un signal de flux de données et pour désactiver ledit signal de flux de données à l'état réception.
  5. Aide auditive selon l'une quelconque des revendications 1 à 4, dans laquelle la transmission entre ladite unité de communication sans fil (120) et un dispositif sans fil (115) est modulée par impulsions.
  6. Aide auditive selon la revendication 5, dans laquelle ladite modulation par impulsions correspond au flux de données excitant ladite unité active (210).
