Embodiment
The embodiment that is described in more detail below is the preferred embodiments of the present invention.
The spatial orientation that the present invention is based on receiving coil can move this understanding in certain angle limit.This is subjected to guaranteeing the restriction of radio transmission function on the one hand, and the interior operational space of duct also is subjected to the restriction on the appearance on the other hand.All leads that have electric current to flow through have played the effect that produces the induction antenna of disturbing magnetic field in hearing aids or the hearing assistor.The amplitude and the direction in the magnetic field that is orientated about reception antenna depended in magnetic field to the interference effect of reception antenna.Lead now can be respectively be oriented on how much according to the different spaces of receiving coil and be directed, and makes the coupling of magnetic field in reception antenna be minimized.Magnetic field can be by this measure not only partly but also be retained as far as possible little in bigger space to the interference effect of receiving coil.
Even in order under the situation of hearing aids, also to guarantee to send optimum wireless radio transmission with receiving coil and arrange in parallel to each other.In in-the-ear hearing aid, antenna or coil are in a certain border that the orientation by duct determines, therefore perpendicular to panel plane ground orientation.Now, if as normal conditions the lead-in wire in the in-the-ear hearing aid is guided in panel plane, then lead expands into current circuit and produces magnetic field, and magnetic field mainly is parallel to the reception antenna orientation.This has caused maximum interference and coupling.
Yet, do not have regulation to be launched into the current circuit that is parallel to panel plane according to the present invention, but expand into current circuit, illustrated in Fig. 2 perpendicular to panel plane with lead-in wire.
In Fig. 2, provided the panel 10 that is equipped with battery 11 and circuit board 12 particularly.The parallel axes of battery 11 promptly is parallel to the main extension plane of panel 10 in panel plane.Metal bow 13 is used for electric current is transmitted to circuit board 12 from battery 11.The metal bow is constructed rigidly and is made by a kind of strip-shaped conductive material.This electric conducting material does not design at this with insulating, because it does not contact with electrode other electronic device in addition of battery 11.
In selected example, the metal bow is configured to L shaped.The leg 131 of bow stretches out and vertically protrudes on the panel plane along the radial direction of battery from the axle of battery.The one leg 132 in addition of metal bow 13 extends on the surface of shell of battery 11 along the axial direction of battery.Link to each other integratedly with battery contact 133 and remain in the specific section of panel 10 at its free end first leg 131.Second leg 132 is connected with circuit board 12 on its free end, and this can't see in Fig. 2.Therefore, metal bow 13 has formed the part of the ring that is essentially rectangle, and the parallel axes of this straight-flanked ring is moved towards in panel plane.Therefore alternating current component in metal bow 13 has caused the magnetic field with the principal component that is parallel to panel plane.
Because reception antenna almost vertically is arranged on the panel 10 usually as mentioned above, promptly its major directional component is perpendicular to panel plane, so be substantially perpendicular to reception antenna by metal bow 13 disturbing magnetic fields that cause.With this, minimized the influence of interference field.
Because metal bow is firm member and is welded on the battery contact 133 or itself is the part of battery contact 133, thus with lay loose wiring and compare and reduced structure tolerance.Structure for so-called " semi-modular " in-the-ear hearing aid, promptly, first panel-shaped that will have the signal processing electronic device as mentioned like that becomes first module, and the housing that will have receiver forms second module, and receiving coil and remaining hearing aids electronic device are irrespectively placed, and the position that clearly limits of metal bow is essential for the function of transmission system.
Under the orientation of reception antenna must remain on technology prerequisite in certain border, the position of receiving coil in hearing aids can change, because minimized the interference effect to bigger area of space according to the present invention.Therefore can realize a kind of hearing aids constructing technology that reception antenna and other parts are irrespectively placed.
Eliminated further by solution according to the present invention and usually only to have produced the expense in the additive wire loop of counter field in the part.In addition, can construct hearing assistor in the littler ear by bigger freely making about the locus of reception antenna.
