Claims (6)
- Hörhilfesystem (100) mit einer Kommunikationseinheit (120) zum induktiven Senden und Empfangen von Signalen, wobei die Kommunikationseinheit (120) aufweist:eine aktive Einheit (210), die ausgebildet ist, eine induktive Antenne (220) in einem Sendezustand mittels einer mit der Antenne (220) gekoppelten ersten Induktivität (255) zu treiben;einer Frequenzbestimmungseinheit (215), die mit der Antenne (220) mittels einer zweiten Induktivität (256) gekoppelt ist und ausgebildet ist, in dem Sendezustand die Sendefrequenz zu steuern und in einem Empfangszustand empfangene Signale an einen Empfänger-Frontend (225) zu liefern; dadurch gekennzeichnet, dass die aktive Einheit (210) eine dritte Induktivität (254) aufweist, die mit der Antenne (220) gekoppelt ist und ausgebildet ist, eine Rückkopplung von der Frequenzbestimmungseinheit (215) an die aktive Einheit (210) zu liefern.
- Hörhilfe gemäß Anspruch 1, bei dem die Frequenzbestimmungseinheit (215) die zweite Induktivität (256) und eine Kapazität (257) umfasst.
- Hörhilfe gemäß Anspruch 1, bei dem die Antenne (220) ein ferromagnetisches Element zum Koppeln der ersten und der zweiten Induktivität (255, 256) aufweist.
- Hörhilfe gemäß einem der Ansprüche 1 bis 3, bei dem die aktive Einheit ausgebildet ist, die induktive Antenne (220) in dem Sendezustand mittels eines Datenstromsignals zu treiben und in dem Empfangszustand das Datenstromsignal zu deaktivieren.
- Hörhilfe gemäß einem der Ansprüche 1 bis 4, bei dem die Übertragung zwischen der drahtlosen Kommunikationseinheit (120) und einem drahtlosem Gerät (115) puls-moduliert ist.
- Hörhilfe gemäß Anspruch 5, bei dem die Pulsmodulation einem Datenstrom entspricht, der die aktive Einheit (210) anregt.
