Die vorliegende Erfindung betrifft eine Hörereinrichtung für eine Hörvorrichtung mit einem länglichen Hörer und einem Ohrpassstück, das eine Bohrung aufweist, in die der Hörer eingesteckt ist. Unter einer Hörvorrichtung wird hier insbesondere ein Hörgerät, aber auch jedes andere am Ohr tragbare Gerät zur Schallausgabe verstanden, wie beispielsweise ein Headset, Kopfhörer und dergleichen.The present invention relates to a hearing device for a hearing device with an elongate receiver and an earmold having a bore into which the earpiece is inserted. A hearing device is understood here to mean in particular a hearing device, but also any other ear-portable device for sound output, such as a headset, headphones and the like.

Hörgeräte sind tragbare Hörvorrichtungen, die zur Versorgung von Schwerhörenden dienen. Um den zahlreichen individuellen Bedürfnissen entgegenzukommen, werden unterschiedliche Bauformen von Hörgeräten wie Hinter-dem-Ohr-Hörgeräte (HdO), Hörgerät mit externem Hörer (RIC: receiver in the canal) und In-dem-Ohr-Hörgeräte (IdO), z.B. auch Concha-Hörgeräte oder Kanal-Hörgeräte (ITE, CIC), bereitgestellt.

Hörgeräte besitzen prinzipiell als wesentliche Komponenten einen Eingangswandler, einen Verstärker und einen Ausgangswandler. Der Eingangswandler ist in der Regel ein Schallempfänger, z. B. ein Mikrofon, und/oder ein elektromagnetischer Empfänger, z. B. eine Induktionsspule. Der Ausgangswandler ist meist als elektroakustischer Wandler, z. B. Miniaturlautsprecher, oder als elektromechanischer Wandler, z. B. Knochenleitungshörer, realisiert. Der Verstärker ist üblicherweise in eine Signalverarbeitungseinheit integriert. Dieser prinzipielle Aufbau ist in FIG 1 am Beispiel eines Hinter-dem-Ohr-Hörgeräts dargestellt. In ein Hörgerätegehäuse 1 zum Tragen hinter dem Ohr sind ein oder mehrere Mikrofone 2 zur Aufnahme des Schalls aus der Umgebung eingebaut. Eine Signalverarbeitungseinheit 3, die ebenfalls in das Hörgerätegehäuse 1 integriert ist, verarbeitet die Mikrofonsignale und verstärkt sie. Das Ausgangssignal der Signalverarbeitungseinheit 3 wird an einen Lautsprecher bzw. Hörer 4 übertragen, der ein akustisches Signal ausgibt. Der Schall wird gegebenenfalls über einen Schallschlauch, der mit einer Otoplastik im Gehörgang fixiert ist, zum Trommelfell des Geräteträgers übertragen. Die Stromversorgung des Hörgeräts und insbesondere die der Signalverarbeitungseinheit 3 erfolgt durch eine ebenfalls ins Hörgerätegehäuse 1 integrierte Batterie 5.Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer. The input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil. The output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized. The amplifier is usually integrated in a signal processing unit. This basic structure is in FIG. 1 shown using the example of a behind-the-ear hearing aid.

HdO-Hörgeräte mit externer Hörereinheit (RIC-Geräte) bedürfen speziell hinsichtlich der Hörereinheit eines besonderen Augenmerks. So ist es wünschenswert, wenn die externe Hörereinheit beispielsweise in einer so genannten "Micro Earmold", d. h. einer sehr kleinen Bauform eines Ohrpassstücks, fixiert werden kann.BTE hearing aids with external receiver units (RIC devices) require special attention with regard to the earphone unit. Thus, it is desirable if the external handset unit is in a so-called "Micro Earmold", d. H. a very small design of an earmold, can be fixed.

Um weiterhin den Anforderungen der Akustik zu genügen, sollte die externe Hörereinheit elastisch in dem Ohrpassstück gelagert sein. Zudem soll die externe Hörereinheit vor Verschmutzungen durch Cerumen, Schweiß etc. geschützt sein. Die Hörereinheit sollte außerdem austauschbar sein, und zum Schutz des Hörers ist es günstig, wenn ein Hörer- bzw. Cerumenschutz an der Hörereinheit angebracht werden könnte.In order to continue to meet the requirements of the acoustics, the external receiver unit should be elastically mounted in the earmold. In addition, the external earphone should be protected from contamination by cerumen, sweat, etc. The earphone should also be interchangeable, and to protect the earphone it is beneficial if a earpiece or wax guard could be attached to the earphone.

Aus der Patentschrift DE 10 2004 009 268 B3 ist ein Ohreinsatz für ein Hörsystem bekannt. In eine Otoplastik ist nach akustischen Bedingungen ein Schallaustritt eingeformt. Ein in die Otoplastik integrierter Hörer kann mit Hilfe eines Adapters austauschbar in der Otoplastik befestigt sein.From the patent DE 10 2004 009 268 B3 is an ear insert known for a hearing system. In an earmold acoustical conditions a sound outlet is formed. An earpiece integrated in the earmold can be exchangeably fastened in the earmold with the aid of an adapter.

Darüber hinaus ist aus der Druckschrift DE 85 18 681 U1 eine Hörhilfe bekannt, deren Gehäuse einen sich verjüngenden Durchmesser hat. Mit einem Schnappverschluss, der eine Mehrzahl am äußeren Umfang des Gehäuses liegende Ansätze aufweist, die als Raststufen wirken, an denen beim Einfügen des Gehäuses in die Otoplastik Rastkanten einschnappen, sind Teile der Hörhilfe in der Otoplastik befestigt.In addition, from the document DE 85 18 681 U1 a hearing aid known, the housing has a tapered diameter. With a snap closure, a plurality of lying on the outer circumference of the housing approaches has, which act as latching steps, in which snap when inserting the housing into the earmold latching edges, parts of the hearing aid are mounted in the earmold.

Ferner beschreibt die Patentschrift US RE38,351 E einen Ohrlautsprecher, der mit Hilfe eines elastischen Ohrstücks in ein Ohr eingesetzt werden kann. In das elastische Ohrstück ist ein Gehäuse eingesetzt, in dessen Inneren sich ein Hörer befindet. Der Hörer selbst ist mit einem geschäumten Material in dem Gehäuse gelagert.Furthermore, the patent describes US RE38,351 E an ear speaker that can be inserted into an ear using an elastic earpiece. In the elastic earpiece, a housing is used, in the interior of which a handset is located. The listener itself is stored in the housing with a foamed material.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Hörereinrichtung bereitzustellen, bei der der Hörer in dem Ohrpassstück herausnehmbar, akustisch günstig und dicht gelagert ist.The object of the present invention is to provide a receiver device in which the receiver is removable, acoustically favorable and tightly mounted in the earmold.

Erfindungsgemäß wird diese Aufgabe gelöst durch eine Hörereinrichtung für eine Hörvorrichtung mit einem länglichen Hörer und einem Ohrpassstück, das eine Bohrung aufweist, in die der Hörer eingesteckt ist, sowie einem rohrförmigen Zwischenstück, wobei der Hörer im größten Teil seiner Längserstreckung in das Zwischenstück reibschlüssig eingepresst und das Zwischenstück seinerseits reibschlüssig in die Bohrung des Ohrpassstücks eingepresst ist.According to the invention, this object is achieved by a receiver device for a hearing device with an elongated receiver and an earmold having a bore into which the earpiece is inserted, and a tubular intermediate piece, wherein the handset in the largest part of its longitudinal extension in the intermediate piece frictionally pressed and the intermediate piece in turn is frictionally pressed into the bore of the ear mold.

Das elastische Zwischenstück gewährleistet nicht nur eine einfache Austauschbarkeit des Hörers in dem Ohrpassstück, sondern sorgt auch dafür, dass er größtenteils von dem Ohrpassstück akustisch abgekoppelt ist. Der Anteil an Körperschall, der vom Hörer über das Ohrpassstück zu den Gehörgangswänden des Nutzers der Hörvorrichtung übertragen wird, ist somit deutlich reduziert.The elastic intermediate piece not only ensures easy interchangeability of the earpiece in the earmold, but also ensures that it is acoustically decoupled from the earmold for the most part. The proportion of structure-borne noise that is transmitted by the listener via the earmold to the auditory canal walls of the user of the hearing device is thus significantly reduced.

Vorzugsweise ist in das Zwischenstück an dessen Schallaustrittsseite ein Cerumenschutzelement eingepresst. Hierdurch kommt dem Zwischenstück nicht nur die Funktion des Haltens des Hörers, sondern auch die des Haltens des Cerumenschutzes zu.Preferably, a cerumen protective element is pressed into the intermediate piece on its sound outlet side. As a result, the intermediate piece is not only the function of holding the handset, but also the holding of the cerumen protection.

Das Zwischenstück kann ferner an seinem Außenmantel mehrere in Umfangsrichtung verlaufende Rippen aufweisen. Hierdurch können sehr definierte Druck- und Reibungskräfte von dem Zwischenstück auf die Bohrung des Ohrpassstücks ausgeübt werden. Die Kräfte für das Ein- und Auspressen des Zwischenstücks aus der Bohrung des Ohrpassstücks lassen sich so in gewünschter Weise festlegen.The intermediate piece may further comprise on its outer casing a plurality of circumferentially extending ribs. As a result, very defined pressure and frictional forces can be exerted by the intermediate piece on the bore of the ear mold. The forces for the pressing in and out of the intermediate piece from the bore of the earmold piece can thus be determined in the desired manner.

Darüber hinaus kann das Zwischenstück aus Gummi oder einem gummielastischen Kunststoff gefertigt sein. In ein derartiges elastisches Zwischenstück lässt sich der Hörer leicht eindrücken. Ebenso lässt sich das Zwischenstück dann leicht auch in das Ohrpassstück einpressen.In addition, the intermediate piece may be made of rubber or a rubber-elastic plastic. In such an elastic intermediate piece, the handset can be easily pressed. Likewise, the adapter can then easily press into the earmold.

Entsprechend einer ebenfalls bevorzugten Ausführungsform dichtet das Zwischenstück den Hörer in dem Ohrpassstück derart ab, dass von der dem Schallauslass des Hörers gegenüberliegenden Seite des Hörers keine Verschmutzung in den Schallauslass gelangen kann. Dadurch kommt dem Zwischenstück nicht nur eine Abdichtfunktion gegenüber der Seite, die dem Trommelfell zugewandt ist, sondern auch gegenüber der Seite, die im getragenen Zustand nach außen gerichtet ist, zu.According to a likewise preferred embodiment, the intermediate piece seals the receiver in the earmold from such that from the side of the receiver opposite the sound outlet of the receiver, no contamination can enter the sound outlet. As a result, the intermediate piece not only has a sealing function with respect to the side which faces the eardrum, but also with respect to the side which is directed outward in the worn state.

Es wurde bereits angedeutet, dass die oben geschilderte Hörereinrichtung vorzugsweise für ein HdO-Hörgerät mit externem, in einen Gehörgang einsetzbarem Hörer, verwendet wird. Ein derartiger Hörer kann aber auch für Headsets, Musikgeräte und dergleichen eingesetzt werden.It has already been indicated that the above-described earphone device is preferably used for a BTE hearing aid with an external earphone which can be inserted into an ear canal. But such a handset can also be used for headsets, music devices and the like.

At the eardrum facing end face 12, the hollow cylindrical intermediate piece 11 is closed with a cerumen protection element 13. With the Cerumenschutzelemement 13 ensures that the receiver located in the interior of the intermediate piece 11 14 (see. FIG. 3 ) is not contaminated by cerumen.

In FIG 3 ist die Hörereinrichtung von FIG 2 von der Rückseite gezeigt, d. h. von der Seite, die beim Tragen nach außen weist. Der in dem Beispiel von FIG 3 gewählte Hörer 14 ragt aus dem Zwischenstück 12 in axialer Richtung des Zwischenstücks 12 heraus. Das Ohrpassstück 11 aber auch das Zwischenstück 11 kann in seiner axialen Erstreckung jedoch auch solange gewählt sein, dass der Hörer 14 nicht aus dem Zwischenstück 12 ragt.In FIG. 3 is the receiver of FIG. 2 shown from the back, ie from the side facing outward when worn. The one in the example of FIG. 3 selected listener 14 protrudes from the intermediate piece 12 in the axial direction of the intermediate piece 12 out. The earmold 11 but also the intermediate piece 11 may in its axial extent, however be chosen so long that the handset 14 does not protrude from the intermediate piece 12.

In FIG 3 ist ferner zu erkennen, dass aus dem Hörer 14 ein Kabel 15 geführt ist, über das der Hörer angesteuert wird. Am anderen Ende des Kabels 15 befindet sich ein Adapter 16, der an ein Hörgerät anzuschließen ist, so dass dem Hörer 14 die entsprechenden Signale bereitgestellt werden können.In FIG. 3 It can also be seen that from the handset 14, a cable 15 is guided over which the handset is controlled. At the other end of the cable 15 is an adapter 16, which is to be connected to a hearing aid, so that the listener 14, the corresponding signals can be provided.

In FIG 4 ist die externe Hörereinrichtung der FIG 2 und FIG 3 einschließlich eines kurzen Stücks des Kabels 15 bzw. dessen Schutzhülle im Längsschnitt dargestellt. Die äußere Kontur des Gehäuses des Hörers 14 ist in das elastische, zylindrische Zwischenstück 11 eingebettet. Hierzu kann in dem Zwischenstück eine in axialer Richtung durchgehende, entsprechend konturierte Aussparung vorgesehen sein. Um den Halt in dem Zwischenstück 11 zu verbessern, besitzt der Hörer 14 einen Schallauslassstutzen 17 mit umlaufendem Widerhaken 18.In FIG. 4 is the external handset of the 2 and FIG. 3 including a short piece of cable 15 and its protective sheath shown in longitudinal section. The outer contour of the housing of the receiver 14 is embedded in the elastic, cylindrical intermediate piece 11. For this purpose, in the intermediate piece a continuous, correspondingly contoured recess can be provided in the axial direction. In order to improve the hold in the intermediate piece 11, the receiver 14 has a sound outlet 17 with circumferential barbs 18th

An seinem Außenumfang besitzt das zylinderförmige Zwischenstück 11 Rippen 19, die in dem gewählten Beispiel in Umfangsrichtung verlaufen. Sie bestehen aus dem gleichen elastischen Material wie das Zwischenstück 11.On its outer circumference has the cylindrical intermediate piece 11 ribs 19 which extend in the selected example in the circumferential direction. They consist of the same elastic material as the spacer 11.

In dem Ohrpassstück 10 befindet sich eine definierte Bohrung 20, die in etwa den gleichen Innendurchmesser beisitzt wie das Zwischenstück 11 ohne die Rippen 19. In diese Bohrung 20 wird die Einheit aus Hörer 14 und elastischem Zwischenstück 11 eingepresst. Die Rippen 19 pressen dabei an den Innenumfang des Ohrpassstücks 10 und werden entsprechend eingedrückt.In the earmold 10 there is a defined bore 20 which is approximately the same inner diameter beisitzt as the intermediate piece 11 without the ribs 19. In this bore 20, the unit of earphone 14 and elastic spacer 11 is pressed. The ribs 19 press against the inner circumference of the earmold 10 and are pressed accordingly.

Nach der Montage der Einheit bestehend aus Hörer 14 und Zwischenstück 11 in das Ohrpassstück 10 kann von der Stirnseite 12 ein Cerumenschutz 13 in die Aussparung des Zwischenstücks 11 eingedrückt werden. Der Cerumenschutz 13 ist hier trichterförmig ausgebildet und weist an seiner Oberfläche eine Membran auf. Der Trichter des Cerumenschutzes 13 reicht bis zum Schallauslassstutzen 17 des Hörers 14, so dass der vom Hörer 14 produzierte Schall durch den Cerumenschutz 13 nach außen geführt wird und der Hörer gleichzeitig durch die Membran des Cerumenschutzes 13 vor Verschmutzungen geschützt ist. Im Falle einer Verschmutzung der Membran des Cerumenschutzes 13 ist dieser leicht aus dem elastischen Zwischenstück 11 zu entnehmen und auszutauschen.After mounting the unit consisting of earphone 14 and spacer 11 in the earmold 10 can be pressed from the front side 12 a wax guard 13 in the recess of the intermediate piece 11. The wax guard 13 is here funnel-shaped and has at its Surface on a membrane. The funnel of Cerumenschutzes 13 extends to the sound outlet 17 of the handset 14 so that the sound produced by the handset 14 is guided by the cerumen protector 13 to the outside and the listener is simultaneously protected by the membrane of the wax guard 13 from contamination. In the case of contamination of the membrane of Cerumenschutzes 13 this is easy to remove from the elastic spacer 11 and replace.

Für den Austausch des Hörers 14 wird vorzugsweise ein Werkzeug benutzt, das in FIG 5 dargestellt ist. Andernfalls besteht die Gefahr, dass der Hörer 14 am Kabel 15 aus dem Ohrpassstück 10 bzw. dem Zwischenstück 11 gezogen wird, wodurch die elektrischen Kontakte des Hörers unter Umständen mechanisch überbelastet werden.For the replacement of the handset 14 is preferably a tool used in FIG. 5 is shown. Otherwise, there is a risk that the handset 14 is pulled on the cable 15 from the ear mold piece 10 or the intermediate piece 11, whereby the electrical contacts of the listener may be mechanically overloaded under certain circumstances.

Das in FIG 5 dargestellte Werkzeug 21 besitzt im Wesentlichen einen zylinderförmigen Abschnitt, dessen Durchmesser in etwa dem der Bohrung 20 im Ohrpassstück 10 entspricht. Mit dem Werkzeug 21 lässt sich dann das Zwischenstück 11 aus dem Ohrpassstück 10 drücken, wobei der Stift bzw. das Werkzeug 21 mit einer Stirnseite gegen die Stirnseite 12 des Zwischenstücks 11 drückt. Hierbei sollte das Cerumenschutzelement 13 bereits entnommen sein, so dass es nicht bricht bzw. beschädigt wird. Auch der Hörer 14 selbst wird durch das Ausdrücken mit dem Werkzeug 21 nicht beschädigt, denn er befindet sich im Inneren des Zwischenstücks 11 axial von der Stirnseite 12 zurückgesetzt.This in FIG. 5 shown tool 21 has substantially a cylindrical portion whose diameter corresponds approximately to that of the bore 20 in the earmold 10. The adapter 21 can then be pressed out of the earmold 10 with the tool 21, the pin or the tool 21 pressing against the end face 12 of the intermediate piece 11 with one end face. Here, the cerumen protection element 13 should already be removed so that it does not break or be damaged. Even the listener 14 itself is not damaged by the expressions with the tool 21, because it is located in the interior of the intermediate piece 11 axially back from the end face 12.

Die in den FIG 2 bis FIG 5 dargestellte Hörereinrichtung besitzt den Vorteil, dass sie rasch und einfach wechselbar ist. Ferner kann durch die Lagerung des Hörers über die komplette Länge der Bohrung kein Cerumen, Schweiß, Feuchtigkeit etc. in den Hörer gelangen. Durch die Verwendung eines elastischen Materials ist der Hörer außerdem akustisch vorteilhaft gelagert. Da des Weiteren das elastische Zwischenstück 11 den Hörer 14 an der Rück- bzw. Außenseite im Ohrpassstück 10 abdichtet, kann kein Schmutz zwischen das Ohrpassstück 10 und den Hörer gelangen. Zur Reinigung der externen Hörereinrichtung ist es damit möglich, die komplette Einheit z. B. in einem Ultraschallbad zu reinigen. Dies bedeutet, dass der Hörer 14 nicht zwangsläufig aus dem Ohrpassstück 10 entfernt werden muss.The in the 2 to FIG. 5 The handset device shown has the advantage that it can be exchanged quickly and easily. Furthermore, no cerumen, sweat, moisture, etc. can get into the receiver through the storage of the listener over the entire length of the hole. By using an elastic material, the handset is also stored acoustically advantageous. Further, since the elastic intermediate piece 11 seals the listener 14 on the back or outer side in the earmold 10, no dirt between the Earpiece 10 and the listener arrive. To clean the external receiver device, it is thus possible, the complete unit z. B. to clean in an ultrasonic bath. This means that the handset 14 does not necessarily have to be removed from the earmold 10.
