Headset loop antenna for audio devices

摘要

The present invention relates to a headset device, an audio device and methods of receiving a radio signal via the headset device, wherein the headset device comprises at least one first conductor for supplying an audio signal to a respective ear-piece, a second conductor arranged in a loop configuration for providing a magnetic antenna, and a connector (50) having at least one respective first connecting portion (3, 4) for providing a connection to the at least one first conductor (140), a second connecting portion (1) for providing a connection to a first end of the second conductor (70), and a third connecting portion (2) for providing a connection to a second end of the second conductor (70), wherein an output of the magnetic antenna is provided between the second and third connecting portions (1, 2). At the audio device, an impedance transformer (10) is coupled to the second and third connecting portions at its primary side and to an amplifier (20) at its secondary side.
