Definitions

  • the invention relates to a hearing aid with wireless remote control.
  • the signal is then fed to a shift register 17 for code recognition, from which it reaches a decoder 18; there the signal is decrypted so that it arrives via connections 19, 20, 21 and 22 to switch 5 or to a sound shield 7 or electronic, ie remote-controlled, potentiometer 8.
  • the lines 19 to 22 also have connections 23, to which a manually operable control 25 can be connected, which is shown in FIG.
  • This signal is then fed to the modulation of a clock frequency control 33, to which the signals of a timer 34, which defines the duration of the logical ⁇ , and the signals of a timer 35, which specifies the duration of the logical 1, also arrive.
  • the signal is processed so that it then arrives at a clock frequency generator 36, where it is modulated with the clock frequency in the ultrasound range.
  • the intensity of the signals is increased in an amplifier 37 so that they are then emitted via a loudspeaker 38 and can act on the microphone 3.

Claims (6)

  1. Appareil de correction auditive, dont au moins des parties de ses fonctions réglables sont commandées au moyen d'une télécommande sans fil, et dans lequel aussi bien les éléments de correction auditive que les éléments servant à régler les fonctions de l'appareil et un récepteur à ultrasons pour des signaux ultrasonores délivrés par un appareil de commande séparé pour réaliser la télécommande de ces fonctions sont logés dans un boîtier porté sur la tête, et dans lequel un microphone d'écoute (3), qui peut convertir les ultrasons en dehors de sa gamme de transmission pour le son audible en signaux électriques, est utilisé en tant qu'élément récepteur pour les signaux de commande ultrasonores, et dans lequel les signaux audibles et les signaux ultrasonores, qui sont reçus par le microphone (3), sont délivrés sous la forme de signaux électriques par l'intermédiaire de branches, dont l'une aboutit à la partie (1) de l'appareil de correction auditive et dont l'autre aboutit, après traversée d'un filtre (13) bloquant tous les signaux en dehors des fréquences ultrasonores, à la partie de télécommande (2) de l'appareil de correction auditive.
  2. Appareil de correction auditive suivant la revendication 1, dans lequel le filtre qui bloque tous les signaux en dehors des fréquences ultrasonores, est réalisé sous la forme d'un filtre passe-haut (13), qui est passant à partir des fréquences ultrasonores et en aval duquel sont branchés un redresseur (14) et un filtre passe-bas (15), à l'aide desquels les signaux parviennent, en vue de leur traitement numérique ultérieur, à un déclencheur de Schmitt (16), à un registre à décalage (17) et à un décodeur (18), l'appareil de commande contenant un générateur d'ultrasons, qui délivre, par l'intermédiaire d'un haut-parleur (38), des signaux ultrasonores codés au moyen d'une unité de commande à touches (30).
  3. Appareil de correction auditive suivant la revendication 2, dans lequel les signaux décodés dans le décodeur sont envoyés, par l'intermédiaire de liaisons (19 à 22), à un commutateur inverseur (5), à un dispositif de réglage de tonalité (7) ou à un potentiomètre télécommandable (8) de la partie (1) de l'appareil de correction auditive, et les liaisons (19 à 22) possèdent des bornes (23) pour une unité manuelle de commande à touches (25), qui peut être raccordée à ces bornes et comporte des touches d'actionnement (24.1 à 24.4), à l'aide desquelles des signaux de commande peuvent être envoyés au commutateur inverseur (5) pour réaliser la commutation entre le microphone (3) et la bobine réceptrice à induction (4), au dispositif de réglage de tonalité (7) pour modifier la réponse en fréquence audio (réponse en fréquence audible) ou au potentiomètre (8) pour modifier l'intensité acoustique.
  4. Appareil de correction auditive suivant la revendication 1, dans lequel la transmission des signaux de commande est prévue dans la gamme des ultrasons, de 25 à 50 kHz.
  5. Appareil de correction auditive suivant la revendication 1, dans lequel les circuits de commande contenus dans la partie (1) de l'appareil de correction auditive et dans la partie de télécommande (2), sont réalisés sous la forme de modules intégrés.
  6. Appareil de correction auditive suivant la revendication 1, dans lequel la transmission des signaux de télécommande se situe dans une zone de résonance du microphone, située dans la gamme des ultrasons.
