Definitions

  • the invention relates to an in-the-ear hearing device with a faceplate attached to an otoplastic, which at least partially carries the device electronics, in particular in the form of a semimodule, the device electronics protruding into the otoplastic.
  • Such a hearing device is known from EP-A-210 550.
  • the semimodule is designed as a plug-in module, the electrical connections being made by contact tongues.
  • the rotary knob of a potentiometer is located outside the faceplate. To access the battery compartment, the module must be disengaged and removed.
  • a similar in-the-ear device is known from DE-U-87 13 369, but in which the battery compartment is arranged in the faceplate and is accessible from the outside and can be closed by means of a cover.
  • DE-A 37 19 830 shows an in-the-ear hearing aid in which the electronics module is mounted in the faceplate so that it can be tilted out in order to access the battery compartment on the bottom.
  • the tiltable module has a cover plate, which is either an integral part of the module or is designed as a large rotary knob on the potentiometer.
  • EP-A 196 366 shows a two-part housing in which the device electronics is located. The two parts are locked together and the adjusting bolt of the potentiometer is led out through the upper housing part and connected to a large rotary knob that can be pulled off the housing to access the other setting means.
  • the advantage of this version is that the large rotary knob hides the technology behind it. It is disadvantageous, however, that it can also be operated undesirably if one strokes the hair and that removing the rotary knob and putting it back on is hardly possible if the hearing aid is in the ear.
  • the object of the invention is to provide an in-the-ear hearing aid of the type mentioned in such a way that the adjustment of the potentiometer and possibly further trimming resistors is possible without having to take the hearing aid out of the ear, but nevertheless the technical adjustment means in normal Wear the hearing aid remain invisible and that the hearing aid can finally be hidden behind a decorative element.
  • a base plate of a multi-part decorative element is attached to the faceplate, which has at least in the central region a recess that enables access to the adjusting means of the hearing aid, and that a cover plate of the Decorative element on the base plate is detachably supported and / or is movably mounted on this between a covering position that at least largely covers the recess and an exposed position that at least partially exposes it.
  • the invention has significant advantages.
  • the base plate Since the faceplate is usually sunk more or less deeply in the concha and is otherwise individually contoured for the respective wearer, the base plate represents an adaptation element that increases the construction height, so that the outer surface of the base plate comes at least in one plane to touch the marginal areas of the concha.
  • the cover plate and the base plate can both be designed as a decorative element. This case allows the cover plate to be made smaller circumferentially than the base plate. It is equally possible, however, to design the cover plate so large that it completely covers the base plate.
  • the base plate can, for example, be firmly connected to the faceplate, for example screwed on, while the cover plate, which in contrast to the prior art has no technical function, is preferably pivotally mounted in its plane, for example above its center of mass.
  • a magnetic body is used at the greatest possible distance from the pivot axis of the cover element in this and in the base plate, such that the two magnetic bodies are aligned in the cover position of the cover plate and lock the cover plate in this cover position.
  • the base plate can have a standard shape.
  • the cover plate can also be equipped with such magnets, the separating surfaces of the two plates preferably also having complementary elevations and depressions or edge configurations which form a positive connection or at least one positioning aid.
  • the cover plate can be detached from the base plate with a single handle, making the adjustment means accessible. Replacing the cover plate is particularly easy thanks to the combined positive-locking magnetic seat, because the cover plate orientates itself even in the event of an initial misalignment and reaches the cover position.
  • This version has the further advantage that different decorative plates can be used as interchangeable plates, whereby thanks to the standard assignment of the holding magnets, no individual adjustment is necessary, as would be the case, for example, if the decorative plate was directly on the faceplate to be anchored.
  • cover plate directly on the faceplate in a removable or pivotable manner, as it is of course also possible to arrange the two-part decorative element easily removable from the faceplate, for example by three miniature magnets can be arranged in the base plate and magnets in the corresponding places in the faceplate.
  • the cover plate, but also the base plate can have a sound-permeable grid-like structure.
  • a solid cover plate is preferably with a through channel e.g. in the form of a hole to allow the sound to reach the microphone.
  • An in-the-ear hearing device has a faceplate 12 with an earmold 16 behind it and engaging in the auditory canal 14. In the middle area of the faceplate there is a microphone opening 18, a flap 20 with a battery compartment behind it and an adjustment button 22 of a potentiometer.
  • the adjustment knob 22 protrudes as FIG. 5 illustrates beyond the faceplate 12 level.
  • the faceplate 12 depends on the anatomy of the ear individually contoured and has locking bushes 24 at suitable points, which are designed to receive locking pins 26, which are arranged on the bottom of a one-piece decorative element 28, not shown.
  • the decorative element 28 consists of a base plate 30, which has the locking pins 26 and a cover plate 32.
  • the cover plate 32 is pivotably mounted on the base plate 30 by means of a pivot pin 34 in a plane parallel to the base plate 30 level.
  • the bottom plate 30 has one in FIG. 3 crest-like contoured recess 36, the size of which is such that the microphone opening 18, the flap 20 for the battery compartment and the adjusting knob 22 for the potentiometer are accessible.
  • This adjustment button 22 can protrude sufficiently far beyond the top surface of the base plate 30 for ease of use, the cover plate 32 then having a corresponding base-side depression 38 in the central region which extends to the edge on one side of the cover plate.
  • the base plate 30 has a larger peripheral contour than the cover plate 32.
  • the base plate 30 is shaped such that it overlaps the tragus T and the anthelix A.
  • a hole 40 is usually provided in the cover plate 32, which creates a sound inlet channel and opens in the region of the recess 36 of the base plate 30.
  • the cover plate is designed that part of this recess 36 including the microphone hole 18 is exposed, that is, is not covered by the cover plate 32. In this version, an additional sound inlet duct in the cover plate is unnecessary.
  • FIG. 6 shows an embodiment in which the base plate 30 is overlapped on all sides by the cover plate 32.
  • the base plate 30 has approximately the contour of the faceplate 12.
  • the circumference of the cover plate is therefore substantially larger than that of the base plate, which here only forms a functional part without a decorative effect.
  • the cover plate 32 carries a cast-in pivot pin, which is anchored in the cover plate 32 by means of a transverse pin, protrudes on the base side and has a thread at the projecting end, with which it is screwed into a threaded piece 42 which is cast in the base plate 30.
  • the cover plate 32 can thus be pivoted from the cover position into the release position, in which the recess 36 of the base plate 30 is exposed, as in the embodiment described above; however, it can also be pivoted through a number of full rotations in order to completely unscrew it from the base plate. As a result, the cover plate 32 becomes a quick-change plate.
  • Variously designed cover plates can thus be anchored to the base plate 30.
  • the pivot pin 34 is located in the area near the edge at the upper end of the base plate 30 and in the diametrically opposite lower edge area the base plate 30 has a magnet 44 inserted flush with the surface, to which a magnet 46 inserted flush in the cover plate 32 is assigned.
  • the two magnets 44, 46 are aligned at right angles to the level of the base plate 30 and since the poles of the same name face each other, this combination of magnetic bodies 44, 46 secures the cover plate 32 in its cover position.
  • the decorative element 28 can be removed from the faceplate 12 as a whole and the locking takes place by means of three magnet body combinations between the base plate 30 and the faceplate 12.
  • the magnet 44 already mentioned is inserted into the base plate 30 near the lower edge region.
  • two magnets 50, 52 spaced as far apart as possible are used near the upper edge region.
  • the faceplate has magnets 48, 54, 56 assigned to these three magnets 44, 50, 52 and it should be pointed out that the magnet 44 in the base plate 30 has a double function, since, as already described, it acts with the magnet 46 to Securing the position of the cover plate 32 together and also holding the entire decorative element 28 together with the magnet 48 together with the two further pairs of magnetic bodies 50, 54 and 52, 56 on the faceplate 12.
  • This magnetic liability of the decorative element 28 is combined with a form-fitting seat of the base plate 30 on the faceplate 12.
  • This form-fit seat is formed in the exemplary embodiment in that the base plate 30 has a base 58 at the upper end, which surrounds the faceplate. In the lower half, the base plate 30 has two tabs 60, 62 which project downwards and which grip around the faceplate. Additionally or alternatively, the mutually facing separating surfaces of base plate 30 and faceplate 12 can have complementary elevations and depressions, so that there is only a single form-fitting position between the two parts 12, 30, in which the magnet body pairs 44, 48; 50, 54 and 52, 56 are aligned with each other.
  • the user can thus optionally pivot the cover plate 32 upwards about the bolt 34 in order to access the potentiometer rotary knob 22, the battery compartment 20 or other setting means, but he can also lift the decorative element 28 as a whole from the faceplate 12.
  • the cover plate 32 is pivoted for the first time, the positive connection between the base plate and the faceplate prevents a relative displacement of these two parts.
  • the cover plate 32 covers the setting means of the hearing aid and thus protects against unintentional actuation, while a simple finger movement is sufficient to move the cover plate into an exposed position or to remove the entire decorative element 28 in order to actuate the setting means while the hearing aid is in the ear.
