Description

Die Erfindung betrifft ein Im-Ohr-Hörgerät mit einer, an einer Otoplastik befestigten Faceplate, die wenigstens teilweise die Geräteelektronik insbesondere in Form eines Semimoduls trägt, wobei die Geräteelektronik in die Otoplastik hineinragt.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.

Aus der EP-A-210 550 ist ein derartiges Hörgerät bekannt. Das Semimodul ist als Steckmodul ausgebildet, wobei die elektrischen Verbindungen durch Kontaktzungen hergestellt werden. Der Drehknopf eines Potentiometers ist außerhalb der Faceplate angeordnet. Um an das Batteriefach heranzukommen, muß das Modul ausgerastet und herausgenommen werden.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.

Aus der DE-U-87 13 369 ist ein ähnliches Im-Ohr-Gerät bekannt, bei dem jedoch das Batteriefach von außen zugänglich in der Faceplate angeordnet und mittels eines Deckels verschließbar ist.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.

Die DE-A 37 19 830 Zeigt ein Im-Ohr-Hörgerät, bei dem das Elektronikmodul in der Faceplate herauskippbar gelagert ist, um an das bodenseitige Batteriefach heranzukommen. Das kippbar gelagerte Modul hat eine Abdeckplatte, die entweder fester Bestandteil des Moduls ist oder als großflächiger Drehknopf des Potentiometers ausgebildet ist.DE-A 37 19 830 shows an in-the-ear hearing aid in which the electronics module is tiltably mounted in the faceplate 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.

Die EP-A 196 366 zeigt ein zweiteiliges Gehäuse, in dem sich die Geräteelektronik befindet. Die beiden Teile sind miteinander verrastet und der Einstellbolzen des Potentiometers ist durch das obere Gehäuseteil herausgeführt und mit einem großflächigen Drehknopf verbunden, der vom Gehäuse abgezogen werden kann, um an die übrigen Einstellmittel heranzukommen. Der Vorteil dieser Ausführung besteht darin, daß der großflächige Drehknopf die dahinterliegende Technik verdeckt. Nachteilig ist aber,daß er auch unerwünscht betätigt werden kann, wenn man sich das Haar streicht und daß das Abnehmen des Drehknopfes und das Wiederaufsetzen kaum möglich ist, wenn sich das Hörgerät im Ohr befindet.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 design is that the large rotary knob hides the technology behind it. However, it is disadvantageous that it can also be operated undesirably if one strokes the hair and that it is hardly possible to remove the rotary knob and put it back on when the hearing aid is in the ear.

Aufgabe der Erfindung ist es, ein Im-Ohr-Hörgerät der eingangs genannten Art so auszubilden, daß das Einstellen des Potentiometers und ggf. weiterer Trimmwiderstände möglich wird, ohne das Hörgerät aus dem Ohr herausnehmen zu müssen, daß aber gleichwohl die technischen Einstellmittel beim normalen Tragen des Hörgerätes unsichtbar bleiben und daß schließlich das Hörgerät hinter einem Dekorelement verborgen werden kann.The object of the invention is to provide an in-the-ear hearing aid of the type mentioned at the outset in such a way that the adjustment of the potentiometer and possibly further trimming resistors is possible without having to remove the hearing aid from 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.

Diese Aufgabe wird bei einem Im-Ohr-Hörgerät der eingangs genannten Art dadurch gelöst, daß auf der Faceplate eine Bodenplatte eines mehrteiligen Dekorelementes befestigt ist, die mindestens im Mittelbereich eine, den Zugang zu Einstellmitteln des Hörgerätes ermöglichende Ausnehmung aufweist, und daß eine Abdeckplatte des Dekorelementes an der Bodenplatte abnehmbar gehaltert und/oder an dieser zwischen einer, die Ausnehmung wenigstens zum größten Teil abdeckenden Abdeckstellung und einer diese wenigstens zum Teil freilegenden Freilegestellung beweglich gelagert ist. Die Erfindung bringt wesentliche Vorteile. Da die Faceplate in der Regel mehr oder weniger tief in der Concha versenkt liegt und im übrigen für die jeweilige Trägerperson individuell konturiert ist, stellt die Bodenplatte ein Adaptionselement dar, das die Aufbauhöhe vergrößert, sodaß die Außenfläche der Bodenplatte mindestens in eine Ebene kommt, um die randständigen Bereiche der Concha zu tangieren. Die Abdeckplatte und die Bodenplatte können beide je als Dekorelement ausgebildet sein. Dieser Fall erlaubt es, die Abdeckplatte umfangsmäßig kleiner auszubilden als die Bodenplatte. Genausogut ist es aber möglich, die Abdeckplatte so groß auszubilden, daß sie die Bodenplatte völlig überdeckt. Die Bodenplatte kann z.B. mit der Faceplate fest verbunden, z.B. verschraubt sein, während die Abdeckplatte, die im Gegensatz zum Stand der Technik keine gerätetechnische Funktion hat,vorzugsweise in ihrer Ebene verschwenkbar gelagert ist, z.B. oberhalb ihres Massenschwerpunktes. Man braucht dann nur die Abdeckplatte nach oben zu schwenken, um die Einstellmittel freizulegen, um sie betätigen zu können. Nach dem Loslassen schwenkt die Abdeckplatte von selbst in ihre Abdeckstellung. Dabei liegt es im Rahmen der Erfindung, die Abeckplatte so leichtgängig zu lagern, daß sie bei einer Bewegung des Kopfes Eigenbewegungen ausführt, wodurch der Dekoreffekt verstärkt wird. Gemäß einer alternativen Ausgestaltung wird im größtmöglichen Abstand von der Schwenkachse des Abdeckelementes in diesem und in der Bodenplatte jeweils ein Magnetkörper eingesetzt, derart, daß die beiden Magnetkörper in der Abdeckstellung der Abdeckplatte ausgefluchtet sind und die Abdeckplatte in dieser Abdeckstellung arretieren.This object is achieved in an in-the-ear hearing aid of the type mentioned in that 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 removably supported and / or is movably mounted on this between a cover position that at least largely covers the recess and an exposed position that at least partially exposes it. The invention has significant advantages. Since the faceplate is generally 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 circumferentially smaller than the base plate. However, it is equally possible 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. One then only needs to pivot the cover plate upwards to expose the adjusting means in order to be able to operate them. After releasing the cover plate swings into its cover position by itself. It is within the scope of the invention to mount the cover plate so smoothly that it moves itself when the head moves executes, which enhances the decorative effect. According to an alternative embodiment, 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.

Während die Faceplate individuell konturiert ist, kann die Bodenplatte eine Standardform haben. In dieser können nun z.B. mehrere Magneten an vorgegebenen Stellen eingesetzt werden und die Abdeckplatte kann ebenfalls mit solchen Magneten bestückt sein, wobei vorzugsweise noch die Trennflächen beider Platten komplementäre Erhöhungen und Vertiefungen und/oder Randkonfigurationen aufweisen, die miteinander einen Formschluß oder mindestens eine Positionierhilfe bilden. Bei dieser Ausführung kann die Abdeckplatte mit einem einzigen Griff von der Bodenplatte gelöst werden, wodurch die Einstellmittel zugänglich sind. Das Wiederaufsetzen der Abdeckplatte ist dank des kombinierten Formschluß-Magnet-Sitzes besonders einfach, denn die Abdeckplatte orientiert sich auch bei anfänglicher Fehlausrichtung selbst und gelangt in die Abdeckstellung. Diese Ausführung bringt den weiteren Vorteil, daß verschiedene Dekorplatten als Wechselplatten verwendet werden können, wobei dank der Standardzuordnung der Haftmagnete keine individuelle Anpassung nötig ist, wie dies z.B. der Fall wäre, wenn die Dekorplatte direkt auf der Faceplate zu verankern wäre.While the faceplate is individually contoured, the base plate can have a standard shape. For example, several magnets can now be inserted in this position and the cover plate can also be equipped with such magnets, the separating surfaces of the two plates preferably also having complementary elevations and depressions and / or edge configurations which form a positive connection or at least one positioning aid. In this embodiment, 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 adaptation is necessary, as would be the case, for example, if the decorative plate was placed directly on the faceplate to be anchored.

Dennoch liegt es im Rahmen der Erfindung, die Abdeckplatte direkt an der Faceplate abnehmbar oder wegschwenkbar zu lagern, wie es natürlich auch möglich ist, das zweiteilige Dekorelement von der Faceplate leicht abnehmbar anzuordnen, indem z.B. drei Miniaturmagnete in der Bodenplatte und an den entsprechenden Stellen Magnete in der Faceplate angeordnet werden. Diese Ausbildung ist Teilgegenstand vom unabhängigen Anspruch 7 der die Aufgabe ebenfalls löst.Nevertheless, it is within the scope of the invention to mount the cover plate directly on the faceplate so that it can be removed or pivoted away, as is of course also possible to arrange the two-part decorative element so that it can be easily removed 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. This training is part of the independent claim 7 which also solves the task.

Die Abdeckplatte, aber auch die Bodenplatte können einen schalldurchlässigen gitterartigen Aufbau haben. Eine massive Abdeckplatte ist vorzugsweise mit einem Durchgangskanal z.B. in Form einer Bohrung versehen, um den Schall an das Mikrofon gelangen zu lassen.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.

Ein Im-Ohr-Hörgerat weist eine Faceplate 12 mit dahinterliegender und in den Gehörgang 14 eingreifender Otoplastik 16 auf. Im Mittelbereich der Faceplate befinden sich eine Mikrofonöffnung 18, eine Klappe 20 mit dahinterliegendem Batteriefach und ein Einstellknopf 22 eines Potentiometers. Der Einstellknopf 22 ragt, wie FIG. 5 veranschaulicht, über die Ebene der Faceplate 12 hinaus. Die Faceplate 12 ist je nach der Anatomie des Ohres individuell konturiert und weist an passenden Stellen Rastbuchsen 24 auf, die zur Aufnahme von Rastzapfen 26 ausgebildet sind, welche bodenseitig an einem nicht gezeigten einstückigen Dekorelement 28 angeordnet sind. Das Dekorelement 28 besteht im Ausführungsbeispiel aus einer Bodenplatte 30, die die Rastzapfen 26 aufweist und einer Abdeckplatte 32. Die Abdeckplatte 32 ist mittels eines Schwenkzapfens 34 an der Bodenplatte 30 in einer zur Ebene der Bodenplatte 30 parallelen Ebene schwenkbar gelagert. Die Bodenplatte 30 hat eine in FIG. 3 wappenartig konturierte Ausnehmung 36, deren Größe so bemessen ist, daß die Mikrofonöffnung 18,die Klappe 20 für das Batteriefach und der Einstellknopf 22 für das Potentiometer zugänglich sind. Dieser Einstellknopf 22 kann zur leichten Bedienbarkeit ausreichend weit über die Deckfläche der Bodenplatte 30 vorstehen, wobei dann die Abdeckplatte 32 im Mittelbereich eine entsprechende bodenseitige Vertiefung 38 aufweist, die auf einer Seite der Abdeckplatte bis zum Rand reicht.An in-the-ear hearing device has a faceplate 12 with otoplastic 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 adjusting knob 22 of a potentiometer. The knob 22 protrudes, as FIG. 5 illustrates beyond the faceplate 12 level. The faceplate 12 is depending on the anatomy of the ear is 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. In the exemplary embodiment, 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 pivotally 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.

In diesem Ausführungsbeispiel hat die Bodenplatte 30 eine größere Umfangskontur als die Abdeckplatte 32. Die Bodenplatte 30 ist so geformt, daß sie den Tragus T und die Anthelix A übergreift. Üblicherweise wird in der Abdeckplatte 32 eine Bohrung 40 vorgesehen, die einen Schalleintrittskanal schafft und im Bereich der Ausnehmung 36 der Bodenplatte 30 mündet. Im Ausführungsbeispiel ist die Abdeckplatte jedoch so gestaltet, daß ein Teil dieser Ausnehmung 36 einschließlich des Mikrofonloches 18 freiliegt, also von der Abdeckplatte 32 nicht abgedeckt ist. Bei dieser Ausführung ist ein zusätzlicher Schalleintrittskanal in der Abdeckplatte entbehrlich.In this exemplary embodiment, the base plate 30 has a larger circumferential 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. In the exemplary embodiment, however, 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 zeigt eine Ausführung, bei der die Bodenplatte 30 von der Abdeckplatte 32 allseitig übergriffen wird. Die Bodenplatte 30 hat angenähert die Kontur der Faceplate 12. Der Umfang der Abdeckplatte ist also wesentlich größer als der der Bodenplatte, die hier nur ein Funktionsteil ohne Dekorwirkung bildet.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.

Die Abdeckplatte 32 gemäß FIG. 6 trägt einen eingegossenen Schwenkbolzen 34, der mittels eines Querstiftes in der Abdeckplatte 32 verankert ist, bodenseitig vorsteht und am vorstehenden Ende ein Gewinde aufweist, mit dem er in ein Gewindestück 42 eingeschraubt ist, das in der Bodenplatte 30 eingegossen ist. Die Abdeckplatte 32 kann also wie bei der vorbeschriebenen Ausführungsform aus der Abdeckstellung in die Freigabestellung geschwenkt werden, in welcher die Ausnehmung 36 der Bodenplatte 30 freiliegt; sie kann aber auch um eine Anzahl Volldrehungen verschwenkt werden, um sie vollständig aus der Bodenplatte herauszuschrauben. Dadurch wird die Abdeckplatte 32 zu einer Schnellwechselplatte. An der Bodenplatte 30 können somit verschiedenartig gestaltete Abdeckplatten verankert werden. Der Schwenkzapfen 34 befindet sich im randnahen Bereich am oberen Ende der Bodenplatte 30 und im diametral gegenüberliegenden unteren Randbereich weist die Bodenplatte 30 einen oberflächenbündig eingesetzten Magneten 44 auf, dem ein in der Abdeckplatte 32 bodenseitig bündig eingesetzter Magnet 46 zugeordnet ist. In der Abdeckstellung der Abdeckplatte 32 sind die beiden Magneten 44, 46 rechtwinklig zur Ebene der Bodenplatte 30 ausgerichtet und da die ungleichnamigen Pole einander zugewandt sind sichert diese Magnetkörperkombination 44, 46 die Abdeckplatte 32 in ihre Abdeckstellung.The cover plate 32 according to FIG. 6 carries a cast-in pivot pin 34, which is anchored in the cover plate 32 by means of a cross 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. As in the embodiment described above, 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; 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. In the cover position of the cover plate 32, the two magnets 44, 46 are oriented at right angles to the plane 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.

Im Ausführungsbeispiel gemäß FIG. 6-9 ist das Dekorelement 28 insgesamt von der Faceplate 12 abnehmbar und die Arretierung erfolgt durch drei Magnetkörperkombinationen zwischen der Bodenplatte 30 und der Faceplate 12. In die Bodenplatte 30 ist nahe dem unteren Randbereich der schon genannte Magnet 44 eingesetzt. Weiterhin sind nahe dem oberen Randbereich zwei möglichst weit voneinander distanzierte Magneten 50, 52 eingesetzt. Die Faceplate weist diesen drei Magneten 44, 50, 52 zugeordnete Magnete 48, 54, 56 auf und es ist darauf hinzuweisen, daß der Magnet 44 in der Bodenplatte 30 eine Doppelfunktion hat, denn er wirkt, wie schon beschrieben, mit dem Magnet 46 zur Lagesicherung der Abdeckplatte 32 zusammen und hält außerdem zusammen mit dem Magneten 48 das ganze Dekorelement 28 zusammen mit den beiden weiteren Magnetkörperpaaren 50, 54 und 52, 56 an der Faceplate 12. Diese Magnethaftung des Dekorelementes 28 ist kombiniert mit einem formschlüssigen Sitz der Bodenplatte 30 auf der Faceplate 12. Dieser Formschlußsitz wird im Ausführungsbeispiel dadurch gebildet, daß die Bodenplatte 30 am oberen Ende einen bodenseitigen Ansatz 58 aufweist, der die Faceplate einfaßt. In der unteren Hälfte hat die Bodenplatte 30 zwei seitliche nach unten vorstehende Lappen 60, 62, die die Faceplate umgreifen. Zusätzlich oder alternativ können auch die einander zugewandten Trennflächen von Bodenplatte 30 und Faceplate 12 komplementäre Erhöhungen und Vertiefungen aufweisen, sodaß es nur eine einzige Formschluß-Paßstellung zwischen den beiden Teilen 12, 30 gibt, in denen die Magnetkörperpaare 44, 48; 50, 54 und 52, 56 miteinander jeweils ausgerichtet sind.In the embodiment shown in FIG. 6-9, 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. Furthermore, 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 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.

Der Benutzer kann also wahlweise die Abdeckplatte 32 um den Bolzen 34 nach oben schwenken, um an den Potentiometer-Drehknopf 22, das Batteriefach 20 bzw. weitere Einstellmittel heranzukommen, er kann aber auch das Dekorelement 28 insgesamt von der Faceplate 12 abheben. Beim erstgenannten Verschwenken der Abdeckplatte 32 verhindert die Formschlußverbindung zwischen Bodenplatte und Faceplate eine Relativverlagerung dieser beiden Teile.The user can thus optionally pivot the cover plate 32 upward 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. When the cover plate 32 is pivoted for the first time, the positive connection between the base plate and faceplate prevents a relative displacement of these two parts.

In allen Ausführungsbeispielen ist gewährleistet, daß die Abdeckplatte 32 die Einstellmittel des Hörgerätes abdeckt und damit gegen unbeabsichtigte Betätigung schützt, während gleichwohl eine einfache Fingerbewegung ausreicht, um die Abdeckplatte in eine Freilegestellung zu bewegen oder das ganze Dekorelement 28 abzunehmen, um die Einstellmittel zu betätigen, während das Hörgerät sich im Ohr befindet.In all exemplary embodiments it is ensured that the cover plate 32 covers the adjustment 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.
