Abstract
A receiver device for receiving audio signals from a remote source has a magnetic loop antenna for receiving radio frequency signals carrying audio signals, a signal processing unit for reproducing audio signals from the radio frequency signals received by the antenna, an output interface which is capable of being mechanically connected to an input interface of a hearing instrument to be worn at a user's ear in order to supply the audio signals from the signal processing unit as input to the hearing instrument, and a housing enclosing the antenna and the signal processing unit. The antenna is designed as a printed board circuit with a loop-shaped conductor on an at least partially flexible insulating substrate. A first portion defines a first plane and a second portion defines a second plane, the first plane and second planes being oriented at an angle of 60° to 120° relative to each other.
