Definitions

  • the present invention relates to a hearing device with a receiver, which has a receiver housing, and an electrical coil, which is mounted directly on a portion of the hearing housing.
  • a hearing device is understood to mean in particular a hearing aid, a headset, a headphone or the like.
  • Hearing aids are portable hearing aids that are used to care for the hearing impaired.
  • different types of hearing aids such as behind-the-ear hearing aids (BTE) and in-the-ear hearing aids (ITO), e.g. also Concha hearing aids or canal hearing aids (CIC), provided.
  • BTE behind-the-ear hearing aids
  • ITO in-the-ear hearing aids
  • CIC canal hearing aids
  • the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
  • bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
  • Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
  • the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
  • the output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized.
  • the amplifier is usually integrated in a signal processing unit. This basic structure is in FIG. 1 shown using the example of a behind-the-ear hearing aid. In a hearing aid housing 1 for carrying behind the ear, one or more microphones 2 for receiving the sound from the environment are installed.
  • a signal processing unit 3 which is also integrated into the hearing aid housing 1, processes the microphone signals and amplifies them she.
  • the output signal of the signal processing unit 3 is transmitted to a loudspeaker or earpiece 4, which outputs an acoustic signal.
  • the sound is optionally transmitted via a sound tube, which is fixed with an earmold in the ear canal, to the eardrum of the device carrier.
  • the power supply of the hearing device and in particular of the signal processing unit 3 is carried out by a likewise integrated into the hearing aid housing 1 battery. 5
  • Handset or loudspeakers in hearing aids generally work according to the electrodynamic principle.
  • the generated magnetic field can not be fully utilized and is partly lost as an interference field to the environment. This unwanted "magnetic radiation” is to shield it. Otherwise, the listener's magnetic field disturbs, for example, the telecoil built into the hearing aid.
  • Mu-metal sheets are used, which shield the magnetic field of a listener to the outside. It is also known to equip the amplifier hearing aids with compensation coils, also to reduce the magnetic radiation of the listener.
  • the antenna coil is wound around the receiver housing.
  • the earphone housing material virtually forms the core of the coil.
  • the precondition for the fact that the receiver coil does not disturb the antenna or telecoil coil is that the receiver housing is magnetically tight. This means that the magnetic field generated by the receiver coil must not go outside to the antenna coil.
  • complete decoupling of both coils is difficult to achieve.
  • the coil wound around the receiver housing not only serves as an antenna coil, but can also be used as a compensation coil. Owns for this the coil has several taps. However, this creates a very complex component, and an exchange of the handset, for example, always connected to an exchange of the antenna coil.
  • the object of the present invention is therefore to propose a simply constructed handset with an effective magnetic shielding.
  • a hearing device having a receiver which has a receiver housing, and an electrical coil which is fastened directly to a section of the receiver housing, wherein the main axis of the electrical coil is perpendicular to the surface of the section of the receiver housing and the electric coil is connected in series with the handset.
  • the electrical coil can be aligned on the receiver housing so that just the magnetically sensitive components in the hearing, z. As the telecoil, be shadowed.
  • the electric coil is formed spirally. As a result, a coil with a low overall height can be realized.
  • the electrical coil may also be an air coil. As a result, dispenses with a coil core, but which is usually not necessary for the magnetic shielding.
  • the electric coil desirably has a polyimide substrate as the support.
  • This can be used in particular as a film.
  • the space requirement of the electric coil can be further reduced.
  • the polyimide also provides sufficient electrical insulation and is also sufficiently mechanically robust.
  • the one in the example of FIG. 2 illustrated handset 4 has a receiver housing 10 and an attached nozzle 11 as a sound outlet.
  • the housing 10 is shown here cuboid but can also be formed, for example, cylindrical or in any other arbitrary shape. Even the edges and corners can be rounded.
  • contacts 12, 13 are arranged for wiring the receiver 4.
  • these contacts 12, 13 may also be arranged at a different location of the receiver housing 10.
  • a spiral-shaped air coil 14 It is applied to a polyimide film 15.
  • coil contacts 16, 17, On the polyimide film 15 are also coil contacts 16, 17, which are connected to the two ends of the coil 14.
  • the polyimide film with the electrical coil 14 and the coil contacts 16, 17 is flexible overall and adapts to the surface of the receiver housing 10. By the low Height of the coil 14 and the film 15 is virtually no additional space required for this compensation coil.
  • the polyimide film 15, which forms the carrier of the coil 14, can be glued on the receiver housing 10, for example. Overall, the size of the compensation coil 14, 15, 16, 17 are selected so that just located in a hearing aid telephone coil is magnetically shadowed by the handset 4.
  • the electric coil 14 extends mainly in a plane parallel to the surface portion of the receiver housing to which it is applied. Its main axis is perpendicular to this surface section.
  • This constellation can not only with a spiral coil, but also z. B. can be achieved with a coiled coil low number of turns.
  • the principle of operation of the air coil 14 is that it forms the opposite field to the interference field of the receiver 4.
  • she is using the receiver coil (in FIG. 2 not shown) connected in series.
  • the polarity of the air coil 14 is observed, so that the magnetic field generated by it is directed opposite to that of the earpiece.
  • FIG. 2 is therefore to operate the handset with the compensation coil a first strand 18 soldered to the handset contact 13.
  • the second handset contact 12 is connected to the coil contact 16.
  • a third strand 20 is soldered to the second coil contact 17.
  • the receiver coil and the compensation coil are thus connected in series.
  • Another advantage of this type of compensation is that each listener receives its own compensation. This makes you independent of the hearing aid amplifier, on which often compensation coils have been arranged. This advantage comes into play when, for example, two manufacturers are used as handset suppliers.
  • the compensation coil of the present invention mounted on the receiver housing may also be combined with a mu-metal and one or more compensation coils on the amplifier.
