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 hereinafter are preferred embodiments of the present invention.

[0020] The invention is based on the recognition that the spatial orientation of the receiving coils can shift within certain angular limits. On the one hand, this is limited by the need to ensure the radio transmission function, and on the other hand, the available space in the ear canal is also limited by the appearance. All current-carrying wires inside a hearing aid or hearing aid act as an induction antenna generating a disturbing magnetic field. The disturbing influence 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 guided geometrically according to different spatial orientations of the receiving coils, so that the coupling of the magnetic field within the receiving antenna is minimized. Interfering influences of the magneti...

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 supplying power to the signal processing device and a device for connecting the power supply unit with the signal processing device Electrically connected electrical conductors. The term "antenna" is here also understood in particular to mean coil parts and coils. Background technique [0002] Hearing aids are wearable hearing aids for the hearing impaired. Different hearing aid structures are available to meet a large number of individual needs, such as behind-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. Additionally, there are bone conduction hearing aids, implantable or vibrating (tactile) hearing aids on the market. The impaired hearing is ...
