Definitions

  • the invention relates to a circuit board of a hearing aid, a method for producing a circuit board of a hearing aid and a hearing aid.
  • the hearing aid is in particular a hearing aid in each case.
  • Ambient sound is usually recorded by means of an electromechanical sound transducer.
  • the recorded electrical signals are processed by means of an amplifier circuit and introduced into the ear canal of the person by means of a further electromechanical transducer.
  • the recorded sound signals are usually processed, for which purpose a signal processor of the amplifier circuit is usually used. In this case, the amplification is matched to any hearing loss of the hearing aid wearer.
  • hearing aid devices Different types are known.
  • the so-called “behind-the-ear devices” are worn between the skull and the auricle.
  • the introduction of the amplified sound signal into the auditory canal takes place here by means of a sound tube.
  • Another common embodiment of a hearing aid device is an "in-the-ear device” in which the hearing aid device itself is inserted into the auditory canal.
  • the auditory canal is consequently at least partially closed by means of this hearing aid device, so that apart from the sound signals generated by the hearing aid device, no further sound - or only to a greatly reduced extent - sound can penetrate into the auditory canal.
  • EP 2 835 863 A1 it is therefore known to provide a throttle between the types of components connected to one another for signaling purposes.
  • the throttle suppresses interference introduced into the conductor tracks by means of the radio waves, so that undisturbed operation is still possible.

  • the circuit board has a first electrical component and a second electrical component, which are connected to the base body.
  • a specific function is fulfilled by means of each of the electrical components.
  • each of these electrical components comprises a number of electrical and / or electronic components which are suitably interconnected to form a common circuit.
  • Each of the electrical components is expediently a separate component, which is manufactured independently of the base body and connected to it for assembly and expediently electrically contacted with it.
  • the electrical components are attached to the base body by means of a THT process or an SMD process and are thus electrically contacted with it.
  • the two electrical components are electrically connected directly to one another by means of the conductor track or one of the conductor tracks.
  • the conductor track is, for example, a component of the base body or is attached to it.
  • the conductor tracks are made from a copper.
  • the two electrical components are directly electrically connected to one another. In other words, there is no further component between them by means of which data exchanged between the two electrical components by means of the conductor track is influenced.
  • the two electrical components are preferably connected to one another electrically directly and thus in terms of signal technology by means of a plurality of such conductor tracks, so that a data transmission speed between them is increased.
  • the printed circuit board preferably comprises further electrical components, which are connected to the first electrical component, the second electrical component and / or are connected to one another in terms of signaling by means of one of the conductor tracks.
  • the circuit board also has an electrically conductive, continuous antenna surface.
  • the antenna surface forms an antenna and is made of copper, for example.
  • the antenna surface is manufactured in one work step with the production of the conductor track and in the same way as the conductor track, for example by means of etching.
  • the antenna surface therefore does not have any components that are separate from one another, but these are electrically contacted with one another with low resistance, and there is no galvanic separation.

In particular, it is not necessary to use a specific filter or the like which is introduced into the conductor track and / or the data lines for signaling purposes and / or which is connected upstream of one of the electrical components for signaling purposes. As a result, fewer components are required, which reduces installation space. Manufacturing costs are also reduced in this way.

This also provides electrical insulation between the conductor track and the antenna surface.

If the position and the shape of the cutouts have been determined, this shape and this position of the cutout are expediently also used for subsequent circuit boards without the antenna surface being stimulated in each case. Thus, a manufacturing process is shortened. As an alternative to this, the antenna surface is excited for each printed circuit board and the cutout adapted to this is created. Manufacturing tolerances are thus also taken into account, which increases reliability

Due to the recess 36, the intrinsic impedance of the antenna surface 30 is changed, specifically to the impedance of the transceiver 32.
  • the first to third work steps 44-48 are carried out in particular at least partially by means of software. It is also possible to carry out the method 42 several times in succession, the fourth work step 50 also being carried out by means of software.
  • the cutouts 36 are not actually made in the antenna surface 30 until the last run of the method 42.
  • the method 42 thus performs a characteristic mode analysis by means of numerical field simulation of the entire antenna surface 30, which does not yet have a cutout 36.
  • the third work step 48 the current distribution of the modes is determined, and the modes are selected which are to be excited when the hearing aid 2 is in operation, that is to say in particular the first Frequency range.
  • the recess 36 or the plurality of recesses 36 is then placed in such a way that the selected modes are efficiently excited and, at the same time, the input impedance of the antenna surface 30 is adapted to the transceiver 32.
  • the recess 36 is placed in the current maxima of the selected mode.
  • the antenna surface 30 can then be excited by the transceiver 32 at the edges of the recess 36 and the excitation and the antenna characteristic, that is to say the characteristic of the antenna surface 30, can be measured.
  • the placement of the recess 36 and the subsequent excitation of the antenna surface 30 by means of the transceiver 32 as well as the measurement of the adaptation and the antenna characteristic are repeated several times, with an additional recess 36 expediently being used each time so that the Number of recesses 36 is increased.
  • the existing recess 36 is changed.
  • one or more recesses 36 are thus made in the antenna surface 30, the transceiver 32, that is to say the RF transceiver, being in contact with the antenna surface 30 via the feed points 34 on opposite edges of the antenna surface 30.
  • the transceiver 32 that is to say the RF transceiver, being in contact with the antenna surface 30 via the feed points 34 on opposite edges of the antenna surface 30.
  • a characteristic mode analysis is carried out, for example.
  • the recess 36 or the recesses 36 are then introduced into the antenna surface 30 where the current distribution of the mode or modes reaches its maximum.
  • the recess 36 is made at a position which it is located between the maximum and the minimum.
  • the transceiver 32 is connected to the antenna surface 30 via the feed points 34 on opposite sides of the recess 36, in particular in the area of its edges.
  • the individual are electrical conductive areas of the antenna surface 30 are not galvanically separated. All electrically conductive areas of the antenna surface 30 are thus galvanically connected to one another, and the connection is in particular made with low resistance. Because of the recess 36, no high impedance is required for electrical excitation in the first frequency range, which is why no additional electrical components are required. Material costs are thus reduced.
