Claims (2)

  1. Lyttesystem
    1. Lyttesystem, der omfatter en første og en anden anordning, hvor den første anordning er et bærbart høreapparat, der er indrettet til at præsentere et elektrisk udgangsaudiosignal til en bruger af den første anordning, hvor det elektriske udgangsaudiosignal har en fuld båndbredde Affuii, der omfatter en lavfrekvent del og en højfrekvent del, hvor den anden anordning omfatter en sender til trådløs overførsel af et lavfrekvent signal, og den første anordning omfatter a) en modtager til modtagelse af det lavfrekvente signal og b) en båndbreddeforlængerenhed til at konstruere eller frembringe den højfrekvente del af udgangsaudiosignalet, der har en HF-båndbredde AfHF og danner det elektriske udgangsaudiosignal, der har en fuld båndbredde Affuii, som er baseret på det lavfrekvente signal, der har en LF-båndbredde AfLF, og den højfrekvente del har en FIF-båndbredde AfHF, og c) en signalprocessor, der er indrettet til at behandle det lavfrekvente signal og tilvejebringe et behandlet lavfrekvent signal til båndbreddeforlængerenheden, og hvor den anden anordning yderligere omfatter en indgangstransducer til at konvertere en indgangslyd til et elektrisk indgangssignal og en frekvensbegrænsende enhed til at frembringe det lavfrekvente signal, der har en LF-båndbredde AfLF til at blive trådløst overført til den første anordning.
  2. 2. Lyttesystem ifølge krav 1, hvor senderen og modtageren er indrettet til at tilvejebringe en induktiv kobling mellem den første og anden anordning, på hvilken overførslen af det lavfrekvente signal kan være baseret, når den første og anden anordning er placeret i en betjeningsafstand fra hinanden.
