Definitions

  • the invention relates to a specified in claim 1 hearing aid assembly with a neckband and a specified in claim 10 method for the wireless transmission of data between a hearing aid and an external unit.
  • the reception level at a programming device is low because the transmission power of the hearing aids is limited and the hearing aid antennas are made small.
  • the cause is the limited battery capacity and the limited space available in hearing aids.
  • the signal / noise ratio is small, whereby the maximum data rate between hearing aid and programmer is greatly limited. To improve the exact alignment of the antennas to each other is required. Head rotations of a hearing device wearer have an unfavorable effect on the signal / noise ratio.
  • the transmission level in the programmer is high because there is enough room for a battery with a large storage capacity.
  • the signal / noise ratio at the location of the hearing aid is large, whereby a high maximum data rate between the programmer and hearing aid is possible.
  • a precise alignment of the antennas to each other is not essential.
  • the wireless programming of hearing aids is therefore very asymmetrical. There is fast and secure data transfer when the programmer sends data to the hearing aid, but slow and unsafe data transmission when the programmer receives data from the hearing aid. It would therefore be advantageous to find a way to increase the received signal in the programmer.
  • One known solution is to connect the programmer with a neckband, also called a "lanyard".
  • a neckband also called a "lanyard”.
  • the length of the neckband must be as short as possible to minimize the distance between the hearing aid and the programmer.
  • the disadvantage of this is that a use of short necklaces is often rejected by the hearing device users, since the wearing comfort is poor. The negative impact of head turns during a program operation will persist even with short neck collars.
  • a multi-wire loop antenna is integrated into a neckband.
  • the loop antenna is balanced with a capacitor in series resonance to increase the signal strength.
  • the disadvantage of this is that the loop inductance of the loose neckband during use varies greatly, making resonance matching difficult.
  • so-called triggering or separating elements are integrated into the neckband for safety reasons to avoid impending strangulation, which open the neckband when a predetermined force. Since the loop antenna must be guided by the trigger element, often contact problems occur, which limits the functionality.
  • the US 2006/0039577 A1 discloses a hearing aid that can communicate with a remote unit.
  • the unit communicates with the hearing aid via a neck strap having two antennas.
  • the US 6,594,370 B1 discloses a hearing aid arrangement for wireless transmission between a left and a left right hearing aid and a remote control unit using a neckband.
  • the neckband includes two antennas with which data can be exchanged with the left or right hearing aid.
  • the stated object is achieved with the hearing aid assembly with a necking collar of the independent patent claim 1 and the method for the wireless transmission of data between a hearing aid and an external unit of the independent patent claim 6.
  • the neckband can be carried out in a convenient to be worn length and that nevertheless a sufficiently high received signal of the wireless data transmission arrives at the external unit.
  • the second and third antenna can each be an inductive antenna. This ensures secure near-field data transmission with low power requirements.
  • the data from the hearing aid will be coupled into the second antenna and the data coupled into the second antenna can be coupled from the third antenna into the external unit. This offers the advantage of an additional indirect transmission path between hearing aid and external unit.
  • the arrangement comprises at least one first antenna arranged in the hearing device and at least one fourth antenna arranged in the external unit. This allows wireless data exchange.
  • the external unit may be a hearing aid programmer.
  • the second antenna may be located near the hearing aid and the third antenna may be located near the external unit. This improves data transfer.
  • the at least one second antenna can be arranged such that when the hearing device user turns his head, the first antenna approaches the second antenna. This has the advantage that a head rotation has less effect on the power received in the external unit.
  • the arrangement may also comprise two oppositely-oriented diodes which are arranged parallel to the third antenna. As a result, the statutory radio regulations can be met.
  • the arrangement may comprise at least a first and a second capacitor, which are arranged in series with the second and third antenna.
  • resonant circuits can thereby be formed.
  • the at least one second and the at least one third antenna are arranged in a carrying collar.
  • the second antenna may be located near the hearing aid and the third antenna may be located near the external unit.
  • the at least one second antenna can be arranged in such a way that the first antenna of the second antenna is approached during head rotation of a wearer of the hearing aid.
  • the antennas may be inductive antennas.
  • FIG. 1 shows the principle of a wireless data exchange 12 between a hearing aid 1 and a programming device 2 according to the prior art.
  • To change settings of the hearing aid 1 are to be transmitted to the programmer 2 Data exchanged.

  • the antennas 11, 21 are preferably designed as wound on a ferrite core wire coils.

  • a right-handed head rotation of the hearing aid user by a rotation angle 41 deteriorates for the right-worn hearing aid 1, the signal / noise ratio at the location of the fourth antenna 21, since the distance to the programmer 2 and the shadowing by the head 4 increase.
  • FIG. 2 shows the head 4 of a hearing aid wearer with a left and a right hearing aid 1.
  • the hearing aid user carries a attached to a neck 3 handheld programmer 2 around the neck.

  • the series connection is coupled into the second antenna 31 field performance - reduced by the efficiency of Arrangement - coupled to the third antenna 32, to be received after a short distance from the fourth antenna 21 of the programmer 2 as an indirect signal 38.
  • the second antenna 31 is advantageously arranged so that in a head rotation 41, the hearing aid 1, which is rotated away from the programming device 2, moves to the second antenna 31.
