Definitions

  • the present invention relates to a battery contact device for a hearing device, in particular a hearing aid, having a first contact for contacting a first pole of a battery and a second contact for contacting a second pole of the battery.
  • telephone coils are often provided with which telephone signals can be received and emitted inductively.
  • the inductive transmission is relatively susceptible to interference when there are further electrical and / or magnetic components in the range of the transmission path. It has been found that in particular the electromagnetic receiver of a hearing aid interferes with the received or emitted signals of a telephone coil.
  • the battery contacts of a hearing aid also act as jammers. Depending on the shape and current flow, they generate more or less strong magnetic fields and thus reduce the signal-to-noise ratio during signal transmission with the telecoil.
  • a hearing aid in which a parallel spaced second induction coil is provided for suppressing genetic interference fields to a first induction coil.
  • the generated induced voltages act against each other, whereby noise can be minimized.
  • a hearing aid in which the effect of the magnetic interference is reduced by means of a compensation coil and a capacitor connected in parallel with a battery.
  • the object of the present invention is to reduce the caused by battery contacts disturbances of telephone coils.
  • a battery contact device for a hearing device in particular a hearing aid, with a first contact for contacting a first pole of a battery and a second contact for contacting a second pole of the battery, wherein the second contact configured at least in a section as an induction coil is, over which the electricity supplied by the battery can be derived.
  • one of the battery contacts thus receives twice the functionality of the battery contacting and the interference field compensation.
  • the installation space for a separate compensation coil can be saved.
  • the induction coil serving as a contact has a spiral shape. This can be achieved with a very small footprint a high compensation effect.
  • a contact region may be provided to contact the corresponding pole of the battery. This also allows smaller battery poles to be contacted. In principle, however, it is also possible that the contacting the battery pole in the outer area of the spiral takes place. In this case, the further current flow takes place from the center of the spiral. With this variant, correspondingly larger pole faces can be contacted well.
  • the two contact forces are substantially perpendicular to each other. This ensures that one of the two contacts the battery, for example, from the top and the other of the two contacts contacted the battery from the side. Through this spatial arrangement, the interference can be further reduced.
  • a hearing aid is powered by a battery 1 with power.
  • This battery 1 is substantially cylindrical and has a first pole 2 on its front side and a second pole 3 on the lateral surface or the opposite end side.
  • the pole 2 at the front or top usually represents the positive pole of the battery.
  • the negative pole of the battery 1 is formed by the jacket.
  • the positive pole 2 of the battery is contacted with a conventional contact spring 4.
  • the negative pole 3 of the battery 1 is formed with a spiral contact 5 according to the invention, which acts as a coil.
  • the first contact 4 can also be used as a plus battery contact and the spiral contact 5 will be referred to as a minus battery contact.
  • the hearing aid pulls current via the contacts 4 and 5
  • an electromagnetic interference field is generated by the current flow in the contacts. Due to the lateral placement of the negative battery contact 5, however, this interference field is reduced.
  • the coil at the contact 5 also a possible interference field of an electromagnetic handset is compensated.
  • Essential for the reduction is the exact alignment and arrangement of the coil of the contact 5.
  • all these parameters depend on the specific design of the hearing aid.
  • the coil of the contact 5 is to be adapted in terms of shape, position and orientation to the spatial design of the hearing aid and its electrical wiring. This adjustment can only be made individually for each hearing aid.
  • both contacts may be provided with an induction coil.
  • the interference field of the battery contacts 4, 5 is reduced.
  • the lateral placement of the battery contact 5 will reduce the interference field of the battery contacts and compensate for the execution of this contact 5 as a coil, the interference field of the hearing aid to a large extent. This is not a separate compensation coil more necessary and the hearing aid can be downsized overall.
  • a helical coil integrated in the contact 5 may also be provided. Although this coil shape increases the necessary space, but it may be in terms of the contact force and the coil effect of advantage.
  • the effect of the interference field compensation according to the invention can be maintained.
  • the coupling factor which is incorporated in the battery contact, reduces the coupling factor with respect to the coupling of interference into the telecoil of a hearing device. Accordingly, the hearing aid can be operated with a higher signal-to-noise ratio.
