Abstract:
The influence of interference from power supply lines in hearing devices is to be reduced. Thus a hearing device with an antenna for receiving and/or sending inductive signals, a signal processing device, to which the antenna is connected, a power supply unit for supplying power to the signal processing device and an electrical conductor for electrical connection of the power supply unit to the signal processing device is provided. The electrical conductor is L-shaped or U-shaped and closely follows the contours of the power supply unit. In addition the electrical conductor forms a part of an essentially round or rectangular ring, the axis of which has a main directional component perpendicular to the longitudinal axis of the antenna. A magnetic field created by the conductor is thus perpendicular to the antenna, so that its magnetic interference influence is reduced.
