Problems solved by technology

However, the disadvantage of the compensation of the induced interference field is that the size of the interference field must be known at least in the order of magnitude
Another disadvantage of this type of wiring is that the wires can get jammed, frayed or loosened when the hearing aid is turned off

Embodiment Construction

[0019] The embodiments described in detail below are preferred embodiments of the present invention.

[0020] The present invention is based on the recognition that the spatial orientation of the receiving coil will move within a certain angular limit. On the one hand, it is restricted by the need to ensure the radio transmission function. On the other hand, the available space in the ear canal is also restricted by appearance. All the wires in the hearing aid or hearing aid that have current flowing through it act as an inductive antenna that generates an interference magnetic field. The interference effect of the magnetic field on the receiving antenna depends on the magnitude and direction of the magnetic field with respect to the orientation of the receiving antenna. The wires can now be respectively guided geometrically according to the different spatial orientations of the receiving coil, so that the coupling of the magnetic field in the receiving antenna is minimized. The i...

Abstract

In order to decrease interference effect of power-supply in a hearing aid, to provide such a hearing aid with an antenna for receiving and / or sending induction signal, a signal processing device (12) connecting with the antenna, a power-supply unit (11) for supplying power to the signal processing device and a conducting object for electric connecting the power supply unit (11) and the signal processing device (12). The conducting object (13) is like L or U-shape and abuts on power-supply unit (11). Furthermore, the conducting object constitutes into one part of a basic round or rectangle ring, the ring axes has a main direction component vertical to the antenna longitudinal axis. Therefore the magnetic field generated by the conducting object (13) vertical to the antenna, minimizing the magnetic interference of the magnetic field.

Description

Technical field [0001] The invention relates to a hearing aid with an antenna for receiving and / or transmitting induction signals, a signal processing device connected to the antenna, a power supply unit for powering the signal processing device, and a power supply unit for connecting the power supply unit and the signal processing device Electrical conductor for electrical connection. The term "antenna" is also understood here in particular as coil parts and coils. Background technique [0002] Hearing aids are wearable hearing aids for the hearing impaired. In response to a large number of individual needs, different hearing aid structures are provided, such as back-of-the-ear hearing aids (HdO), in-ear hearing aids (IdO) and external ear hearing aids. Hearing aids are typically designed to be worn on the outer ear or in the ear canal. In addition, there are bone conduction hearing aids, implantable or vibration (tactile) hearing aids on the market. The impaired hearing is thus...
