Description

Die Erfindung bezieht sich auf ein Hörgerät mit einem Gehäuse, das in ein Ohr einer das Hörgerät tragenden Person (im Folgenden auch "Anwender") einsetzbar ist. Die Erfindung bezieht sich dabei insbesondere auf ein "Instant-Fit-Hörgerät", bei dem das Gehäuse eine nicht individuell angepasste Standard-Form aufweist, wobei ein flexibler Halteschirm, mit dem das Hörgerät im Gehörgang befestigbar ist, auf das Gehäuse aufgesetzt ist.The invention relates to a hearing aid with a housing which can be inserted into an ear of a person wearing the hearing device (hereinafter also referred to as "user"). The invention relates in particular to an "instant-fit hearing aid", in which the housing has a non-individually adapted standard shape, wherein a flexible holding screen, with which the hearing aid can be fastened in the ear canal, is placed on the housing.

Ein Hörgerät dient der Versorgung einer hörgeschädigten Person mit akustischen Umgebungssignalen, die zu einer Kompensation der jeweiligen Hörschädigung entsprechend verarbeitet und insbesondere verstärkt werden. Ein Hörgerät umfasst hierzu üblicherweise einen Eingangswandler, beispielsweise in Form eines Mikrofons, eine Signalverarbeitungseinheit mit einem Verstärker, sowie einen Ausgangswandler. Der Ausgangswandler ist in der Regel als Miniaturlautsprecher realisiert und wird auch als Hörer oder Receiver bezeichnet. Er erzeugt insbesondere akustische Ausgabesignale, die zum Gehör des Patienten geleitet werden und bei diesem die gewünschte Hörwahrnehmung erzeugen.A hearing aid is used to supply a hearing-impaired person with acoustic ambient signals, which are processed according to a compensation of the respective hearing impairment and in particular amplified. A hearing device for this purpose usually comprises an input transducer, for example in the form of a microphone, a signal processing unit with an amplifier, and an output transducer. The output transducer is usually realized as a miniature speaker and is also referred to as a handset or receiver. In particular, it generates acoustic output signals which are conducted to the patient's hearing and produce the desired auditory perception in the patient.

Um den zahlreichen individuellen Bedürfnissen entgegenzukommen, werden unterschiedliche Bauformen von Hörgeräten angeboten. Bei BTE-Hörgeräten (Behind-The-Ear, auch Hinter-dem-Ohr bzw. HdO) wird ein Gehäuse mit Komponenten wie einer Batterie und der Signalverarbeitungseinheit hinter dem Ohr getragen. Je nach Ausgestaltung kann der Receiver entweder direkt im Gehörgang des Trägers angeordnet sein (sogenannte Ex-Hörer-Hörgeräte oder Receiver-in-the-Canal (RIC)-Hörgeräte). Alternativ ist der Receiver innerhalb des Gehäuses selbst angeordnet und ein flexibler, auch als Tube bezeichneter Schallschlauch leitet die akustischen Ausgabesignale des Receivers vom Gehäuse zum Gehörgang (Schlauch-Hörgeräte). Bei ITE-Hörgeräten (In-the-Ear, auch IDO bzw. In-dem-Ohr) wird ein Gehäuse, welches sämtliche funktionale Komponenten einschließlich des Mikrofons und des Receivers enthält, zumindest teilweise im Gehörgang getragen. CIC-Hörgeräte (Completely-in-Canal) sind den ITE-Hörgeräten ähnlich, werden jedoch vollständig im Gehörgang getragen.To meet the numerous individual needs, different types of hearing aids are offered. For BTE hearing aids (behind-the-ear, also behind-the-ear or BTE) a housing with components such as a battery and the signal processing unit is worn behind the ear. Depending on the configuration, the receiver can either be arranged directly in the auditory canal of the wearer (so-called ex-earphone hearing aids or receiver-in-the-canal (RIC) hearing aids). Alternatively, the receiver is arranged inside the housing itself and a flexible, also referred to as a tube sound tube directs the acoustic output signals of the receiver from the housing to the ear canal (tube hearing aids). In ITE hearing aids (in-the-ear, also IDO or in-the-ear), a housing containing all functional components, including the microphone and the receiver, at least partially worn in the ear canal. Completely-in-Canal (CIC) hearing aids are similar to ITE hearing aids, but are worn fully in the ear canal.

Ein Instant-Fit-Hörgerät umfasst in einer herkömmlichen Bauform beispielsweise eine durch eine Frontplatte ("Face-Plate") verschlossene Gehäuseschale ("Shell"). Die Gehäuseschale ist dabei in zwei Halbschalen längsgeteilt, wobei an eine dieser Halbschalen an einem bestimmungsgemäß innenliegenden (d.h. dem Trommelfell zugewandten) Ende eine Schallauslassöffnung angeformt ist. Die Schallauslassöffnung weist einen Gelenkkopf eines Kugelgelenks auf, wobei auf diesen Gelenkkopf der eingangs erwähnte flexible Halteschirm aufsteckbar ist. Die beiden Gehäuseschalen werden nach der Montage der darin aufgenommenen Hörgerätekomponenten miteinander verklebt.An instant fit hearing aid in a conventional design includes, for example, a housing shell ("shell") closed by a faceplate. The housing shell is longitudinally divided into two half-shells, wherein a sound outlet opening is integrally formed on one of these half-shells at an end which is intended to be internal (i.e., facing the eardrum). The sound outlet opening has a joint head of a ball joint, wherein on this condyle of the above-mentioned flexible retaining screen can be plugged. The two housing shells are glued together after mounting the hearing aid components received therein.

Der Erfindung liegt die Aufgabe zugrunde, ein Hörgerät anzugeben, das besonders rationell herstellbar ist.The invention has for its object to provide a hearing aid that is particularly efficient to produce.

Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Anspruchs 1. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen und der nachfolgenden Beschreibung dargelegt.This object is achieved by the features of claim 1. Advantageous embodiments of the invention are set forth in the dependent claims and the description below.

Das erfindungsgemäße Hörgerät umfasst ein Gehäuse, das in einen Gehörgang einer das Hörgerät tragenden Person einsetzbar ist, sowie einen lösbar an dem Gehäuse befestigten oder befestigbaren Halteschirm zur Halterung des Gehäuses in dem Gehörgang. Der Halteschirm ist aus einem flexiblen Material, beispielsweise aus einem Gummi- oder einem Elastomermaterial, gefertigt.The hearing aid according to the invention comprises a housing which can be inserted into an auditory canal of a person carrying the hearing aid, as well as a retaining screen detachably fastened or attachable to the housing for holding the housing in the auditory canal. The retaining screen is made of a flexible material, for example of a rubber or an elastomeric material.

Das Gehäuse umfasst eine einteilige Gehäuseschale ("Shell"), in der eine Baueinheit aufgenommen ist, die zumindest einen Hörer ("Receiver") umfasst. Die Gehäuseschale ist als ein nicht individuell angepasstes Standardteil aus einem starren Material gefertigt.The housing comprises a one-piece housing shell ("shell"), in which a structural unit is accommodated, which comprises at least one receiver ("receiver"). The housing shell is made as a non-customized standard part of a rigid material.

Erfindungsgemäß weist die Gehäuseschale einerseits eine erste frontseitige Öffnung auf, die mit einer Frontplatte ("Face-Plate") verschlossen ist. Andererseits weist die Gehäuseschale eine der ersten Öffnung in etwa gegenüberliegende zweite rückseitige Öffnung auf, wobei die den Hörer umfassende Baueinheit mit einem Haltestutzen aus der rückseitigen Öffnung herausragt, und wobei die Baueinheit durch einen außenseitig (d.h. von außerhalb der Gehäuseschale) auf den Haltestutzen aufgesetzten Sicherungsring an der Gehäuseschale fixiert ist. Der Haltestutzen ist insbesondere zentral von einem Schallkanal durchdrungen, der von dem Hörer erzeugten Schall in den Gehörgang des Anwenders leitet.According to the invention, the housing shell on the one hand on a first front opening, which is closed with a front panel ("face-plate"). On the other hand, the housing shell has one of the first opening approximately opposite the second rear opening, wherein the assembly comprising the listener protrudes with a holding stub from the rear opening, and wherein the assembly by an outside (ie from outside the housing shell) placed on the support stub circlip is fixed to the housing shell. The holding stub is in particular centrally penetrated by a sound channel, which conducts sound generated by the listener into the auditory canal of the user.

Die frontseitige Öffnung der Gehäuseschale ist bei bestimmungsgemäß in den Gehörgang eines Anwenders eingesetztem Hörgeräte-Gehäuse dem Ohreingang zugewandt, während die rückseitige Öffnung dem Trommelfell zugewandt ist.The front opening of the housing shell is facing the ear of the earphone when intended inserted into the ear canal of a user hearing aid housing, while the rear opening facing the eardrum.

Zur Montage des erfindungsgemäßen Hörgeräts wird die den Hörer umfassende Baueinheit durch die frontseitige Öffnung der Gehäuseschale in einen von der Gehäuseschale eingefassten Gehäuseinnenraum eingeführt, wobei der Haltestutzen aus dem Gehäuseinnenraum durch die rückseitige Öffnung nach außen durchgesteckt wird. Anschließend wird der Sicherungsring auf den aus der rückseitigen Öffnung herausragenden Haltestutzen aufgesetzt, so dass die Baueinheit an der Gehäuseschale fixiert ist. Die Baueinheit wird zweckmäßigerweise vor ihrer Montage außerhalb der Gehäuseschale vorgefertigt.To assemble the hearing aid according to the invention, the assembly comprising the earpiece is inserted through the front-side opening of the housing shell into a housing interior enclosed by the housing shell, whereby the support neck is pushed outward from the housing interior through the rear opening. Subsequently, the retaining ring is placed on the protruding from the rear opening holding neck, so that the assembly is fixed to the housing shell. The assembly is advantageously prefabricated before being mounted outside the housing shell.

Durch die einteilige Gehäuseschale ist das Gehäuse des erfindungsgemäßen Hörgeräts vorteilhafterweise im Vergleich zu herkömmlichen Hörgeräten einfacher und in kürzerer Zeit und somit insbesondere kostengünstiger herstellbar. Insbesondere muss die Gehäuseschale des erfindungsgemäßen Hörgeräts vorteilhafterweise nicht verklebt oder verschweißt werden. Durch die einteilige Bauform ist die Gehäuseschale zudem vorteilhafterweise besonders robust und gegenüber mechanischem Versagen besonders zuverlässig gestaltet. Da auch die den Hörer umfassende Baueinheit in der Gehäuseschale weder verklebt noch verschweißt ist, ist diese vorteilhafterweise zerstörungsfrei demontierbar, und erleichtert somit vorteilhaft einen Ausbau des Hörers, beispielsweise zu Reparatur- oder Anpassungszwecken.As a result of the one-piece housing shell, the housing of the hearing device according to the invention is advantageously simpler and less expensive to manufacture compared to conventional hearing aids and thus more cost-effective. In particular, the housing shell of the hearing aid according to the invention advantageously does not have to be glued or welded. Due to the one-piece design, the housing shell is also advantageously particularly robust and designed to be particularly reliable against mechanical failure. Since the comprehensive construction of the listener unit in the housing shell is neither glued nor welded, this is advantageously destructively disassembled, and thus facilitates advantageous an expansion of the handset, for example, for repair or customization purposes.

In einer bevorzugten Ausführungsform umfasst die den Hörer umfassende Baueinheit weiterhin eine Ringantenne (Antennenspule) zur drahtlosen Datenübertragung mittels magnetischer Induktion. Die drahtlose Datenübertragung dient beispielsweise der Kommunikation mit einer Fernbedienung oder (bei einer binauralen Versorgung) der Kommunikation mit einem zweiten Hörgerät. Die Ringantenne ist in bevorzugter Anordnung dem Hörer und dem Haltestutzen zwischengeordnet, wobei die Ringantenne insbesondere den in dem Haltestutzen geführten Schallkanal umfänglich umgreift. Auch in diesem Fall wird die Baueinheit vorzugsweise vor ihrer Montage außerhalb der Gehäuseschale als fest zusammenhängende Baueinheit vormontiert.In a preferred embodiment, the assembly comprising the receiver further comprises a ring antenna (antenna coil) for wireless data transmission by means of magnetic induction. The wireless data transmission is used for example for communication with a remote control or (in the case of a binaural supply) the communication with a second hearing device. The ring antenna is interposed in a preferred arrangement of the handset and the holding stubs, wherein the ring antenna engages in particular circumferentially guided in the holding nozzle sound channel. Also in this case, the assembly is preferably preassembled before the assembly outside the housing shell as a fixed coherent unit.

In einer besonders bevorzugten Ausführungsform ist der Haltestutzen mit einem Außengewinde versehen, wobei der Sicherungsring mit einem korrespondierenden Innengewinde versehen ist. Der Sicherungsring ist in dieser Ausführungsform somit als ein auf den Haltestutzen aufschraubbarer Gewindering ausgeführt. Hierdurch ist die Baueinheit besonders einfach in der Gehäuseschale fixierbar, wobei vorteilhafterweise eine besonders einfach demontierbare Verbindung gegeben ist. Vorzugsweise ist der Sicherungsring dabei mit Hilfe einer Schraubensicherung, vorzugsweise mit einer mechanischen Schraubensicherung, gegen selbsttätiges Lösen gesichert. Beispielsweise weist die rückseitige Öffnung der Gehäuseschale eine Sägezahnkontur auf, die sich mit dem aufgeschraubten und angezogenen Sicherungsring verkrallt.In a particularly preferred embodiment, the holding neck is provided with an external thread, wherein the retaining ring is provided with a corresponding internal thread. The securing ring is thus executed in this embodiment as a threaded ring threaded onto the support neck. As a result, the assembly is particularly easy to fix in the housing shell, which advantageously is given a particularly simple disassemblable connection. Preferably, the locking ring is secured by means of a screw lock, preferably with a mechanical screw lock, against automatic loosening. For example, the rear opening of the housing shell on a Sägezahnkontur, which digs with the screwed-on and tightened circlip.

In einer alternativen aber ebenfalls vorteilhaften Ausführungsform ist der Sicherungsring durch eine andere kraft- und/oder formschlüssige Verbindung auf dem Haltestutzen befestigt. Der Sicherungsring ist in einer Ausführungsform beispielsweise mittels einer Schnapp- oder Rastverbindung an dem Haltestutzen fixiert. Zusätzlich oder alternativ sind Haltestifte zur Fixierung des Sicherungsrings eingesetzt.In an alternative but also advantageous embodiment, the retaining ring is secured by another non-positive and / or positive connection on the support stub. The securing ring is fixed in one embodiment, for example by means of a snap or locking connection to the holding stub. Additionally or alternatively, retaining pins are used for fixing the securing ring.

In einer Ausführungsform weist der Haltestutzen ein Verbindungselement auf, auf das der Halteschirm mit einem korrespondierenden Verbindungselement aufsteckbar oder aufgesteckt ist. Das Verbindungselement weist insbesondere einen Kugelgelenkkopf auf, auf den der Halteschirm mit einer entsprechenden Gelenkpfanne aufsteckbar ist. In montiertem Zustand ist das Verbindungselement zweckmäßigerweise jenseits des Sicherungsrings angeordnet, d.h. bei der Montage der Baueinheit wird der Sicherungsring über das Verbindungselement hinweg auf den Haltestutzen montiert.In one embodiment, the holding stub on a connecting element, on which the holding screen with a corresponding connecting element can be plugged or plugged. The connecting element has in particular a ball joint head, on which the retaining screen can be attached with a corresponding socket. In the assembled state, the connecting element is expediently arranged beyond the securing ring, i. during assembly of the assembly of the locking ring is mounted on the connecting element away on the support stub.

In einer alternativen Ausführungsform weist der Sicherungsring ein Verbindungselement auf, auf das der Halteschirm mit einem korrespondierenden Verbindungselement aufsteckbar oder aufgesteckt ist. Auch in diesem Fall weist das Verbindungselement vorzugsweise einen Kugelgelenkkopf auf. Ist das Verbindungselement an dem Sicherungsring angeordnet, kann es vorteilhafterweise besonders leicht von dem Hörgeräte-Gehäuse entfernt werden, beispielsweise zu Reparaturzwecken oder zur Reinigung. Außerdem kann das Verbindungselement besonders einfach ausgetauscht werden, beispielsweise bei einem Defekt oder wenn auf eine andere Verbindungsmethode gewechselt werden soll. Zusätzlich oder alternativ umfasst der Sicherungsring einen Cerumen-Filter, der dazu dient, den Schallkanal vor eindringendem Schmutz zu bewahren. Auch eine Reinigung oder ein Austausch des Cerumen-Filters ist vorteilhafterweise besonders einfach durchführbar, indem der Sicherungsring demontiert und ggf. gewechselt wird.In an alternative embodiment, the securing ring has a connecting element, on which the retaining screen can be plugged or plugged with a corresponding connecting element. Also in this case, the connecting element preferably has a ball joint head. If the connecting element is arranged on the securing ring, it can advantageously be removed from the hearing aid housing particularly easily, for example for repair purposes or for cleaning. In addition, the connecting element can be exchanged particularly easily, for example in the event of a defect or when changing to a different connection method. Additionally or alternatively, the retaining ring comprises a cerumen filter, which serves to protect the sound channel from penetrating dirt. A cleaning or replacement of the cerumen filter is advantageously particularly easy to perform by disassembling the locking ring and possibly replaced.

Unabhängig davon, ob das Verbindungselement an dem Haltestutzen oder an dem Sicherungsring angeordnet ist, sind in beiden Fällen mehrere Varianten zu dessen Herstellung vorgesehen. In einer Ausführungsform sind das Verbindungselement und der Haltestutzen bzw. der Sicherungsring einstückig (monolithisch) hergestellt. Beispielsweise sind das Verbindungselement und der Haltestutzen bzw. der Sicherungsring gemeinsam als ein Spritzgussteil, beispielsweise aus einem Kunststoff, hergestellt. In einer weiteren Variante sind das Verbindungselement und der Haltestutzen bzw. der Sicherungsring einstückig aus Metall hergestellt. In einer weiteren Variante ist das Verbindungselement aus Metall gefertigt, während der Haltestutzen bzw. der Sicherungsring aus Kunststoff hergestellt ist, wobei das metallische Verbindungselement insbesondere von dem Kunststoff umspritzt ist.Regardless of whether the connecting element is arranged on the holding neck or on the retaining ring, several variants are provided for its production in both cases. In one embodiment, the connecting element and the holding stub or the securing ring are produced in one piece (monolithic). For example, the connecting element and the retaining piece or the retaining ring are made together as an injection molded part, for example of a plastic. In a further variant, the connecting element and the holding connection or the securing ring are produced in one piece from metal. In a further variant, the connecting element is made of metal, while the holding neck or the retaining ring is made of plastic, wherein the metallic connecting element is in particular encapsulated by the plastic.

Unabhängig davon, ob das Verbindungselement an dem Haltestutzen oder an dem Sicherungsring angeordnet ist, sind alternative Ausgestaltungen des Verbindungselements auch denkbar.Regardless of whether the connecting element is arranged on the holding neck or on the retaining ring, alternative embodiments of the connecting element are also conceivable.

Da der Sicherungsring bestimmungsgemäß trommelfellseitig in dem Gehörgang eines Anwenders angeordnet ist, ist dessen zuverlässige Fixierung an der Gehäuseschale, konkret an dem Haltestutzen, besonders wichtig. In einer Ausführungsform ist daher dem Sicherungsring eine Schutzeinrichtung zugeordnet, die dazu dient, bei inkorrektem Sitz des Sicherungsrings einen funktionierenden Betrieb des Hörgeräts zu sperren. Wenn das Hörgerät durch die Schutzeinrichtung gesperrt ist, das Hörgerät also nicht funktioniert, wird der Anwender den korrekten Sitz des Sicherungsrings überprüfen. Der Anwender wird vorteilhafterweise mit vergleichsweise einfachen Mitteln zuverlässig darauf hingewiesen, wenn der Sicherungsring nicht korrekt auf dem Haltestutzen sitzt, und somit das Risiko besteht, dass sich der Sicherungsring in dem Gehörgang des Anwenders löst.Since the circlip is intended to be located eardrum side in the ear canal of a user, whose reliable fixation on the housing shell, specifically on the support stub, is particularly important. In one embodiment, therefore, the protective ring is associated with a protective device which serves to block a functioning operation of the hearing device when the safety ring is incorrectly seated. If the hearing aid is locked by the protective device, ie the hearing aid does not work, the user will check the correct fit of the safety ring. The user is advantageously pointed out with comparatively simple means reliably when the locking ring is not correctly seated on the support stub, and thus there is a risk that solves the circlip in the ear canal of the user.

Die Schutzeinrichtung ist dabei vorzugsweise mechanisch und/oder elektrisch realisiert.The protective device is preferably realized mechanically and / or electrically.

In einer Variante der Schutzeinrichtung ist der Sicherungsring mechanisch an eine Batterieklappe des Hörgeräts gekoppelt, so dass die Batterieklappe nur dann geschlossen werden kann, wenn der Sicherungsring korrekt sitzt. Bei geöffneter Batterieklappe ist die Spannungsversorgung des Hörgeräts in an sich herkömmlicher Weise unterbrochen, so dass hierdurch der Betrieb des Hörgeräts gesperrt ist.In a variant of the protective device, the circlip is mechanically coupled to a battery door of the hearing aid, so that the battery door can only be closed when the circlip is seated correctly. When the battery door is open, the power supply of the hearing aid is interrupted in a conventional manner, so that in this way the operation of the hearing aid is locked.

In einer weiteren Variante der Schutzeinrichtung ist dem Sicherungsring ein elektrischer Kontakt zugeordnet, der nur bei korrektem Sitz des Sicherungsrings geschlossen ist, so dass auch in diesem Fall die Spannungsversorgung des Hörgeräts unterbrochen ist, wenn der Sicherungsring nicht korrekt sitzt.In a further variant of the protective device, an electrical contact is assigned to the securing ring, which is closed only when the securing ring is seated correctly, so that even in this case the power supply of the hearing device is interrupted when the securing ring is not seated correctly.

In einer Ausführungsform übt der Sicherungsring neben seiner Hauptfunktion zur Fixierung der Baueinheit eine weitere Zusatzfunktion aus. Die Zusatzfunktion kann beispielsweise durch eine Schaltfunktion gegeben sein, die mittels des Sicherungsrings betätigbar ist. Die Zusatzfunktion ist vorzugsweise durch eine Ein-/Ausschaltfunktion gegeben, die insbesondere in etwa wie vorstehend beschrieben durch einen elektrischen Kontakt realisiert ist, der jeweils in einer bestimmten Stellung des Sicherungsrings geschlossen oder geöffnet ist. Das Ein- und Ausschalten des Hörgeräts wird dabei für den Anwender vorteilhafterweise vereinfacht. Bei herkömmlichen Hörgeräten ist das Ein- und Ausschalten üblicherweise über das Schließen bzw. Öffnen des Batteriefachs realisiert. Erkanntermaßen kann dabei das Batteriefach verhältnismäßig leicht beschädigt werden. Diese Gefahr besteht bei dem Ein- und Ausschalten mittels des Sicherungsrings vorteilhafterweise nicht. Zusätzlich oder alternativ ist der Sicherungsring dazu eingerichtet und eingesetzt, unterschiedliche Hörgeräteprogramme einzustellen.In one embodiment, the retaining ring exerts a further additional function in addition to its main function for fixing the structural unit. The additional function can be given for example by a switching function that can be actuated by means of the locking ring. The additional function is preferably provided by an on / off function, which is realized in particular approximately as described above by an electrical contact, which is closed or opened in each case in a specific position of the securing ring. The switching on and off of the hearing aid is advantageously simplified for the user. In conventional hearing aids, the switching on and off is usually realized by closing or opening the battery compartment. It can be recognized that the battery compartment can be damaged relatively easily. This danger is advantageously not when switching on and off by means of the locking ring. Additionally or alternatively, the retaining ring is set up and used to set different hearing aid programs.

Die Verwendung des Sicherungsrings als ein Schaltelement ist besonders bevorzugt bei einem Sicherungsring vorgesehen, der zur Halterung der Baueinheit drehbar auf den Haltestutzen aufgeschnappt ist.The use of the securing ring as a switching element is particularly preferably provided in a securing ring which is rotatably snapped onto the holding stub for holding the assembly.

Weiterhin zusätzlich oder alternativ dient die Zusatzfunktion zur Seitenindikation des Hörgeräts. Die Seitenindikation ist insbesondere durch eine Farbcodierung des Sicherungsrings realisiert.Furthermore, additionally or alternatively, the additional function serves to side indication of the hearing aid. The page indication is realized in particular by a color coding of the securing ring.

Vorzugsweise ist die Frontplatte mit Hilfe einer Rastverbindung an der Gehäuseschale befestigt, so dass die gesamte Herstellung des Hörgeräte-Gehäuses ohne einen Klebeschritt erfolgt. Die unaufwändige und kostengünstige Montage des Hörgeräts wird hierdurch weiterhin vorteilhaft unterstützt. Zusätzlich oder alternativ ist die Frontplatte an der Gehäuseschale verschraubt oder mit Hilfe von Haltestiften an der Gehäuseschale befestigt. Bevorzugt ist die Frontplatte hinsichtlich ihrer Dimensionierung an die frontseitige Öffnung der Gehäuseschale angepasst, so dass sie vorteilhafterweise nach ihrer Montage nicht mehr zugeschnitten werden muss - wie herkömmlicherweise vorgesehen.Preferably, the front panel is attached by means of a latching connection to the housing shell, so that the entire production of the hearing aid housing takes place without an adhesive step. The unobtrusive and cost-effective installation of the hearing aid is thereby further advantageously supported. Additionally or alternatively, the front panel is screwed to the housing shell or attached by means of retaining pins on the housing shell. Preferably, the front panel is adapted in terms of their dimensions to the front opening of the housing shell, so that they advantageously no longer needs to be cut after their assembly - as conventionally provided.

In Fig. 1 ist ein Hörgerät 1 gezeigt, dass ein Gehäuse 2 zur Aufnahme von Hörgerätekomponenten umfasst. In der Darstellung ist ein Längsschnitt durch das Hörgerät 1 gezeigt, so dass ein von dem Gehäuse 2 eingefasster Gehäuseinnenraum 3 und die darin ganz oder teilweise aufgenommenen Hörgerätekomponenten, umfassend ein Mikrofon 4, eine Signalverarbeitung 5, einen Hörer 6 ("Receiver") und eine ringförmige Induktionsspule, kurz Ringantenne 7, sichtbar sind.In Fig. 1 For example, a hearing device 1 is shown that comprises a housing 2 for accommodating hearing device components. The illustration shows a longitudinal section through the hearing aid 1, so that a housing interior 3 enclosed by the housing 2 and the hearing aid components wholly or partially accommodated therein, comprising a microphone 4, a signal processor 5, a receiver 6 ("receiver") and a receiver annular induction coil, short ring antenna 7, are visible.

Bei dem Hörgerät 1 handelt es sich um ein in dem Gehörgang zu tragendes "Indem-Ohr"-Hörgerät (IdO-Hörgerät), das als ein sogenanntes "Instant-Fit-Gerät" konzipiert ist. Das Gehäuse 2 ist entsprechend als ein nicht maßgefertigtes Standardteil hergestellt, wobei das Hörgerät 1 einen flexiblen Halteschirm 9 umfasst, der lösbar auf das Gehäuse 2 aufgesetzt ist. Der beispielsweise aus Silikon hergestellte Halteschirm 9 dient dazu, das Gehäuse 2, in dem Gehörgang einer das Hörgerät tragenden Person ("Anwender") zu fixieren. Der Halteschirm 9 ist hier lediglich schematisch angedeutet. Der Halteschirm 9 ist typischerweise als ein von dem Gehäuse 2 separates (losgelöstes oder lösbares) Ersatz- oder Austauschteil ausgeführt. Solche Halteschirme sind herkömmlicherweise beispielsweise als "Click Domes" "Click Sleeves" oder "Ear Molds" bezeichnet.The hearing aid 1 is a "in-the-ear" hearing aid (ITE hearing aid) to be worn in the auditory canal, which is designed as a so-called "instant-fit device". The housing 2 is accordingly manufactured as a non-custom-made standard part, wherein the hearing aid 1 comprises a flexible holding screen 9, which is detachably mounted on the housing 2. The retaining screen 9, for example made of silicone, serves to fix the housing 2 in the auditory canal of a person wearing the hearing device ("user"). The retaining screen 9 is indicated here only schematically. The holding screen 9 is typically designed as a separate or detachable from the housing 2 replacement or replacement part. Such holding screens are conventionally designated, for example, as "Click Domes" "Click Sleeves" or "Ear Molds".

Bei bestimmungsgemäß eingesetztem Hörgerät 1 ist eine als Rückseite 12 bezeichnete Seite des Gehäuses 2 dem Trommelfell des Anwenders zugewandt, während eine als Frontseite 13 bezeichnete Seite des Gehäuses 2 bestimmungsgemäß dem Ohreingang (der Ohrmuschel) zugewandt ist.When used as intended hearing aid 1 is designated as a rear side 12 of the housing 2 facing the eardrum of the user, while designated as a front side 13 of the housing 2 intended to the ear of the ear (the auricle) faces.

Das Gehäuse 2 umfasst eine einteilige Gehäuseschale 15 ("Shell"), sowie eine Frontplatte 16 ("Face-Plate") zum Verschluss der Gehäuseschale 15.The housing 2 comprises a one-piece housing shell 15 ("shell"), as well as a front plate 16 ("face-plate") for closing the housing shell 15.

Die Gehäuseschale 15 hat in groben Zügen eine schlauchartige Form, die sich zur Rückseite 12 hin verjüngt. Die Gehäuseschale 15 weist eine erste, frontseitige (Montage-)Öffnung 20, sowie in etwa gegenüberliegend eine zweite, rückseitige (Montage-)Öffnung 21 auf. Die frontseitige Öffnung 20 dient zum Einsetzen der Hörgerätekomponenten in die Gehäuseschale 15.The housing shell 15 has roughly a tubular shape, which tapers towards the rear side 12. The housing shell 15 has a first, front (mounting) opening 20, as well as approximately opposite a second, rear (mounting) opening 21. The front opening 20 serves to insert the hearing device components into the housing shell 15.

Die rückseitige Öffnung 21 dient zur Montage des Hörers 6 und der Ringantenne 7. Hierzu umfasst das Hörgerät 1 eine Baueinheit 25, die ihrerseits einen aus der Öffnung 21 herausragenden Haltestutzen 27 umfasst, wobei die Ringantenne 7 in dem Haltestutzen 27 aufgenommen ist, und wobei der Hörer 6 an der Ringantenne 7 fixiert ist. Ein von der Rückseite 12 her auf den Haltestutzen 27 aufgesetzter Sicherungsring 30, dient dazu, die Baueinheit 25 an der Gehäuseschale 15 zu fixieren.The rear opening 21 is used to mount the receiver 6 and the ring antenna 7. For this purpose, the hearing aid 1 comprises a structural unit 25, which in turn comprises a protruding from the opening 21 holding stubs 27, wherein the ring antenna 7 is received in the holding stub 27, and wherein the Handset 6 is fixed to the ring antenna 7. An attached from the back 12 forth on the support stub 27 retaining ring 30, serves to fix the assembly 25 on the housing shell 15.

Weiterhin weist der Haltestutzen 27 ein außerhalb des Gehäuses 2 angeordnetes Verbindungselement 35 auf, das mit einem Verbindungselement 36 des Halteschirms 9 korrespondiert, so dass der Halteschirm 9 auf das Gehäuse 2, konkret auf das Verbindungselement 35, aufgeklickt werden kann.Furthermore, the holding stub 27 has a connecting element 35 arranged outside the housing 2, which corresponds to a connecting element 36 of the holding screen 9, so that the holding screen 9 can be clicked onto the housing 2, specifically onto the connecting element 35.

Nachfolgend werden bezugnehmend auf Fig. 1 und Fig. 2 der Aufbau und die Montage der Baueinheit 25 detaillierter erläutert.Hereinafter, referring to Fig. 1 and Fig. 2 the structure and the assembly of the assembly 25 explained in more detail.

Der Haltestutzen 27 ist als ein topfartiges oder becherförmiges Bauteil aus Kunststoff gefertigt. Der Haltestutzen 27 umfasst entsprechend einen flachen Boden 40, und eine an den Boden 40 angrenzende Umfangswand 41, die einen hohlzylindrischen Stutzeninnenraum 42 einfasst. Der Durchmesser des Haltestutzens 27 entspricht in etwa dem Durchmesser der Öffnung 21. An einen Rand der Umfangswand 41 ist ein umlaufender, radial nach außen abragender Anschlag 44 angeformt. Im Montagezustand steckt der Haltestutzen 27 in der Öffnung 21, wobei er mit seinem überwiegenden Teil aus der Gehäuseschale 15 herausragt und im Gehäuseinnenraum 3 mit dem Anschlag 44 an einem die Öffnung 21 umgebenden Rand der Gehäuseschale 15 anliegt. An einer Stelle ist aus dem Anschlag 44 eine - ebenfalls radial nach außen abragende - Haltenase 45 herausgeformt, die im Montagezustand für den Haltestutzen 27 als Verdrehsicherung wirkt.The holding nozzle 27 is made as a pot-like or cup-shaped component made of plastic. The holding stub 27 accordingly comprises a flat bottom 40, and a circumferential wall 41 adjoining the bottom 40, which encloses a hollow-cylindrical stub interior 42. The diameter of the holding nozzle 27 corresponds approximately to the diameter of the opening 21. At one edge of the peripheral wall 41, a circumferential, radially outwardly projecting abutment 44 is formed. In the assembled state of the holding stub 27 is in the opening 21, wherein it protrudes with its predominant part of the housing shell 15 and rests in the housing interior 3 with the stopper 44 at an opening 21 surrounding edge of the housing shell 15. At one point from the stop 44 a - also radially outwardly projecting - retaining lug 45 is formed, which acts in the assembled state for the support stub 27 as rotation.

In den Boden 40 des Haltestutzens 27 ist zentral eine kreisrunde (Schall-)Öffnung 48 eingebracht, die von einem zum Stutzeninnenraum 42 hin vertikal abragenden Kranz 50 eingefasst ist. Nach außen hin schließt an die Öffnung 48 das Verbindungselement 35 an. Bei dem Verbindungselement 35 handelt es sich um ein kurzes Rohrstück aus Metall, das koaxial mit dem Haltestutzen 27 ausgerichtet ist, wobei das Rohrstück mit der Öffnung 48 fluchtet. Das Verbindungselement 35 ist an einem ersten Längsende mit Hilfe von außenseitig umlaufenden Rippen in den Boden 40 des Haltestutzens 27 eingeformt. An seinem zweiten Längsende weitet sich der Innendurchmesser des Verbindungselements 35 in einer Stufe auf. In diesem Bereich ist die Außenfläche des Verbindungselements 35 unter Ausbildung eines Kugelgelenkkopfs 52 nach außen ausgewölbt. Das Verbindungselement 35 ist entsprechend auch als "Ball Spout" bezeichnet.In the bottom 40 of the holding nozzle 27 a circular (sound) opening 48 is centrally introduced, which is bordered by a collar 50 projecting vertically towards the neck interior 42. Outwardly connects to the opening 48, the connecting element 35 at. The connecting element 35 is a short one Pipe piece of metal, which is aligned coaxially with the support stub 27, wherein the pipe piece is aligned with the opening 48. The connecting element 35 is formed at a first longitudinal end by means of externally encircling ribs in the bottom 40 of the holding nozzle 27. At its second longitudinal end, the inner diameter of the connecting element 35 widens in one step. In this area, the outer surface of the connecting element 35 is bulged to form a ball joint head 52 to the outside. The connecting element 35 is also referred to as "ball spout".

Der Haltestutzen 27 weist an einer Außenfläche der Umfangswand 41 ein Außengewinde 54 auf, auf das der Sicherungsring 30 zur Fixierung des Haltestutzens 27 an der Gehäuseschale 15 von außerhalb des Gehäuses 2 aufgeschraubt ist. Der Sicherungsring 30 ist hierzu mit einem auf das Außengewinde 54 abgestimmten Innengewinde 56 versehen. Der Sicherungsring 30 ist gegen selbsttätiges Lösen gesichert. Im Ausführungsbeispiel ist hierzu die Öffnung 21 mit einer dem Sicherungsring 30 zugewandten Sägezahnkontur 58 versehen, die durch ihre Widerhakenstruktur für den angezogenen Sicherungsring 30 als mechanische Schraubensicherung wirkt (vgl. insbesondere Fig. 2).The holding stub 27 has on an outer surface of the peripheral wall 41 an external thread 54, onto which the securing ring 30 for fixing the holding stub 27 to the housing shell 15 is screwed from outside the housing 2. The securing ring 30 is provided for this purpose with a matched to the external thread 54 internal thread 56. The locking ring 30 is secured against automatic release. In the exemplary embodiment, the opening 21 is provided for this purpose with a saw tooth contour 58 facing the securing ring 30, which acts as a mechanical screw lock by its barb structure for the tightened securing ring 30 (cf. Fig. 2 ).

Außenseitig weist der Sicherungsring 30 Längsrippen auf, die zur Montage des Sicherungsrings 30 mit Hilfe eines Werkzeugschlüssels dienen. Im Montagezustand liegt der Sicherungsring 30 mit einem radial nach innen abragenden Dichtrand 60 abdichtend an dem Haltestutzen 27 an. Die Außenfläche der Umfangswand 41 wirkt dabei in einem bodennahen Abschnitt als Dichtfläche. Überwiegend erfolgt die Abdichtung des Gehäuseinnenraums 3 gegenüber eindringendem Schmutz (Feuchtigkeit, Schweiß, Cerumen) jedoch durch eine aus der Verschraubung des Haltestutzens 27 in der Gehäuseschale 15 resultierende Flächenpressung, die insbesondere zwischen dem Anschlag 44 und dem die Öffnung 21 umgebenden Rand wirkt.
Optional ist der Sicherungsring 30 gefärbt, um die Kopfseite zu kennzeichnen, für die das Hörgerät bestimmt ist (beispielsweise rot für die rechte Seite und blau für die linke Seite).On the outside, the securing ring 30 has longitudinal ribs which serve for mounting the securing ring 30 with the aid of a tool wrench. In the assembled state of the locking ring 30 is sealingly abragenden with a radially inwardly projecting sealing edge 60 to the support stub 27. The outer surface of the peripheral wall 41 acts in a near-ground portion as a sealing surface. Mostly, the sealing of the housing interior 3 against penetrating dirt (moisture, sweat, Cerumen), however, by a resulting from the screwing of the holding nozzle 27 in the housing shell 15 surface pressure, which acts in particular between the stop 44 and the opening 21 surrounding edge.
Optionally, the circlip 30 is colored to identify the head side for which the hearing aid is intended (for example, red for the right side and blue for the left side).

In den Stutzeninnenraum 42 des Haltestutzens 27 ist die Ringantenne 7 eingesetzt, wobei beide Teile zumindest annähernd koaxial ausgerichtet sind. Die Ringantenne 7 ist als ein an beiden Längsenden offener zylindrischer Hohlkörper ausgebildet. An ihrem ersten Längsende sitzt die Ringantenne 7 mit ihrem Innendurchmesser auf dem die Öffnung 48 einfassenden Kranz 50 auf. Die Ringantenne 7 ist mit Silikon in dem Haltestutzen 27 eingeklebt. Das Silikon dient hierbei auch zur akustischen Abdichtung eines im Inneren der Ringantenne 7 geführten Schallkanals 62. An ihrem zweiten Längsende weitet sich der Außendurchmesser der Ringantenne 7 in einer Stufe radial nach außen auf, so dass eine Stirnfläche 64 der Ringantenne 7 vergrößert ist.Into the neck interior 42 of the holding nozzle 27, the ring antenna 7 is inserted, wherein both parts are aligned at least approximately coaxially. The ring antenna 7 is formed as an open at both longitudinal ends cylindrical hollow body. At its first longitudinal end, the ring antenna 7 sits with its inner diameter on the rim 48 enclosing the opening 48. The ring antenna 7 is glued with silicone in the support stub 27. At its second longitudinal end, the outer diameter of the ring antenna 7 widens in a step radially outward, so that an end face 64 of the ring antenna 7 is enlarged.

Auf die Stirnfläche 64 der Ringantenne 7 ist der Hörer 6 aufgeklebt, so dass der von dem Hörer 6 erzeugte Schall in den Schallkanal 62 geleitet wird. Dem Hörer 6 und der Ringantenne 7 ist eine dünne Kupferfolie zwischengeklebt, durch die die Ringantenne 7 gegen den Hörer 6 magnetisch abgeschirmt wird. Ein Kunststoff- oder Gummischlauch, wie er herkömmlicherweise zwischen dem Hörer 6 und der Ringantenne 7 vorgesehen ist, entfällt dabei.On the end face 64 of the ring antenna 7 of the handset 6 is glued, so that the sound generated by the handset 6 is directed into the sound channel 62. The receiver 6 and the ring antenna 7, a thin copper foil is glued, by which the ring antenna 7 is magnetically shielded against the handset 6. A plastic or rubber hose, as conventionally provided between the receiver 6 and the ring antenna 7, is omitted.

Zur Montage der Baueinheit 25 wird zunächst die Ringantenne 7 mit dem Hörer 6 (sowie mit der Kupferfolie) verklebt, und anschließend die Ringantenne 7 in dem Haltestutzen 27 verklebt. Anschließend wird die vormontierte Baueinheit 25 als Ganzes - wie insbesondere der Fig. 2 anhand der Darstellung des Haltestutzens 27 zu entnehmen ist - durch die Öffnung 20 in den Gehäuseinnenraum 3 des Gehäuses 2 bzw. der Gehäuseschale 15 eingebracht. Der Haltestutzen 27 wird mit dem Verbdingungselement 35 und dem Boden 40 voran durch die Öffnung 21 gesteckt, und anschließend von außen mit Hilfe des Sicherungsrings 30 fixiert.To mount the assembly 25, the ring antenna 7 is first glued to the handset 6 (as well as the copper foil), and then glued the ring antenna 7 in the support stub 27. Subsequently, the preassembled unit 25 as a whole - as in particular the Fig. 2 can be seen from the illustration of the holding nozzle 27 - introduced through the opening 20 in the housing interior 3 of the housing 2 and the housing shell 15. The holding stub 27 is inserted with the Verbdingungselement 35 and the bottom 40 ahead through the opening 21, and then fixed from the outside by means of the securing ring 30.

Zur weiteren Hörgerätemontage werden die übrigen Hörgerätkomponenten (konkret das Mikrofon 4 und die Signalverarbeitung 5) in an sich herkömmlicher Weise an der Frontplatte 16 montiert und nach deren Verdrahtung (sowie nach der Verdrahtung weiterer Bauteile, wie beispielsweise Batteriekontakte, Programmierkontakte, Hörer 6, Ringantenne 7 etc.) die Frontplatte 16 auf die Öffnung 20 der Gehäuseschale 15 aufgesetzt (vgl. Fig. 3).For further hearing aid installation, the remaining hearing aid components (specifically the microphone 4 and the signal processing 5) are mounted in a conventional manner on the front panel 16 and after the wiring (and after the wiring of other components, such as battery contacts, programming contacts, handset 6, ring antenna 7 etc.), the front plate 16 is placed on the opening 20 of the housing shell 15 (see. Fig. 3 ).

Anhand von Fig. 1 und Fig. 3 ist zu erkennen, dass sich die Öffnung 20 über die gesamte Frontseite 13 der Gehäuseschale 15 erstreckt. Die Frontplatte 16 ist in ihrer Form und Dimensionierung an die hier in etwa ovale Kontur der Öffnung 20 angepasst. Im zusammengesetzten Zustand des Gehäuses 2 liegt die Frontplatte 16 mit einer an ihrem Umfangsrand umlaufenden Stoßfläche 70 an einer Stoßfläche 71 der Gehäuseschale 15 an. Die Frontplatte 16 schließt dabei umfänglich bündig mit der frontseitigen Öffnung 20 der Gehäuseschale 15 ab. Ein Zuschnitt der Frontplatte 16 ist hierbei nicht erforderlich.Based on Fig. 1 and Fig. 3 It can be seen that the opening 20 extends over the entire front side 13 of the housing shell 15. The front plate 16 is adapted in shape and dimensions to the here approximately oval contour of the opening 20. In the assembled state of the housing 2, the front plate 16 bears against an abutting surface 71 of the housing shell 15 with an abutment surface 70 running around on its peripheral edge. The front panel 16 closes circumferentially flush with the front opening 20 of the housing shell 15 from. A blank of the front panel 16 is not required here.

Die Frontplatte 16 umfasst eine frontseitig angeordnete Batterieöffnung 75, welche durch eine verschwenkbare Batterieklappe 76 (vgl. Fig. 1) verschließbar ist. Die Batterieklappe 76 weist eine Batterieaufnahme 78 auf, in der eine Batterie 80 gehalten ist (vgl. Fig. 1). Weiterhin umfasst die Frontplatte 16 elektrische Kontaktelemente 82 (vgl. Fig.3), die in den Gehäuseinnenraum 3 hineinragen, und die bei geschlossener Batterieklappe 76 den elektrischen Kontaktschluss mit der Batterie 80 herstellen.
An der Gehäuseschale 15 und an der Frontplatte 16 sind jeweils Rastelemente angeformt. In der dargestellten Ausführungsform sind die Rastelemente durch einen an der Frontplatte 16 umfänglich umlaufenden wulstartigen Vorsprung 85, der an zugeordneten an der Öffnung 20 ausgeformten Vorsprüngen 86 einschnappt, realisiert. Mittels der Vorsprünge 85,86 wird die Frontplatte 16 durch einen "Schnappverschluss" oder eine "Klickverbindung" an der Gehäuseschale 15 fixiert.The front panel 16 includes a front side battery opening 75, which by a pivotable battery door 76 (see. Fig. 1 ) is closable. The battery door 76 has a battery receptacle 78 in which a battery 80 is held (see. Fig. 1 ). Furthermore, the front panel 16 includes electrical contact elements 82 (see. Figure 3 ), which protrude into the housing interior 3, and establish the electrical contact closure with the battery 80 when the battery door 76 is closed.
On the housing shell 15 and on the front panel 16 each latching elements are integrally formed. In the illustrated embodiment, the locking elements by a on the front plate 16 circumferentially encircling bead-like projection 85, which snaps at associated formed on the opening 20 projections 86 realized. By means of the projections 85,86, the front panel 16 is fixed by a "snap" or a "click connection" on the housing shell 15.

Optional ist die Frontplatte 16 an der Gehäuseschale 15 verschraubt. Zusätzlich oder alternativ ist die Frontplatte 16 an der Gehäuseschale 15 verklebt.Optionally, the front panel 16 is bolted to the housing shell 15. Additionally or alternatively, the front panel 16 is glued to the housing shell 15.

Die Fig. 4 und Fig. 5 erläutern jeweils in schematischer Darstellung zwei unterschiedliche Konzepte zur Realisierung einer Schutzeinrichtung 90. Die Schutzeinrichtung 90 soll sicherstellen, dass der Sicherungsring 30 korrekt auf den Haltestutzen 27 montiert ist, so dass keine Gefahr besteht, dass sich der Sicherungsring 30 in dem Gehörgang des Anwenders von dem Haltestutzen 27 ablöst. Die Schutzeinrichtung 90 sorgt dafür, dass das Hörgerät 1 nur dann betrieben werden kann, wenn der Sicherungsring 30 korrekt auf dem Haltestutzen 27 montiert ist. Gemäß der in Fig. 4 dargestellten Ausführungsform umfasst die Schutzeinrichtung 90 ein ringseitiges Kontaktelement 91, welches an dem Sicherungsring 30 angebracht ist, sowie eine gehäuseseitige elektrische Unterbrechung 92, welche an der Gehäuseschale 15, konkret an einem Umfangsrand der Öffnung 21 angeordnet ist. Das ringseitige Kontaktelement 91 ist beispielsweise als ein leitfähiger Ring an einer der Gehäuseschale 15 zugewandten Stirnfläche des Sicherungsrings 30 ausgeführt. Die gehäuseseitige Unterbrechung 92 unterbricht einen Stromkreis, der zur Strom- bzw. Spannungsversorgung des Hörgeräts 1 dient. Wird der Sicherungsring 30 ausreichend fest angezogen, wird die Unterbrechung 92 durch das Kontaktelement 91 überbrückt und der Stromkreis geschlossen. Somit wird sichergestellt, dass das Hörgerät 1 nur dann betrieben werden kann, wenn der Sicherungsring 30 ordnungsgemäß auf dem Haltestutzen 27 montiert ist.The Fig. 4 and Fig. 5 each illustrate in a schematic representation of two different concepts for the realization of a protective device 90. The protective device 90 is to ensure that the retaining ring 30 is correctly mounted on the support stub 27 so that there is no danger that the retaining ring 30 in the auditory canal of the user of the Retaining piece 27 replaces. The protective device 90 ensures that the hearing aid 1 can only be operated when the circlip 30 is correctly mounted on the support stub 27. According to the in Fig. 4 illustrated embodiment, the protective device 90 comprises a ring-side contact element 91 which is attached to the retaining ring 30, and a housing-side electrical interruption 92, which is arranged on the housing shell 15, specifically at a peripheral edge of the opening 21. The ring-side contact element 91 is embodied, for example, as a conductive ring on an end face of the securing ring 30 facing the housing shell 15. The housing-side interruption 92 interrupts a circuit which serves to supply power or the hearing aid 1. If the retaining ring 30 is tightened sufficiently firmly, the interruption 92 is bridged by the contact element 91 and the circuit is closed. This ensures that the hearing aid 1 can only be operated when the circlip 30 is properly mounted on the support stub 27.

Gemäß der in Fig. 5 dargestellten Ausführungsform umfasst die Schutzeinrichtung 90 eine mechanische Kopplung 95, die den Sicherungsring 30 mechanisch an einen der Batterieklappe 76 zugeordneten Sperrmechanismus 96 koppelt. Die Kopplung 95 und der Sperrmechanismus 96 sind hier lediglich symbolisch angedeutet. Die mechanische Kopplung 95 löst den Sperrmechanismus 96 erst dann, wenn der Sicherungsring 30 korrekt auf den Haltestutzen 27 montiert ist. Andernfalls ist die Batterieklappe 76 durch den Sperrmechanismus 96 blockiert, so dass sie nicht geschlossen werden kann. Bei geöffneter Batterieklappe 76 ist jedoch wiederum ein Stromkreis, der die Stromversorgung des Hörgeräts 1 sicherstellt, unterbrochen, und das Hörgerät 1 kann nicht betrieben werden.According to the in Fig. 5 In the embodiment shown, the protective device 90 comprises a mechanical coupling 95 which mechanically couples the securing ring 30 to a locking mechanism 96 assigned to the battery flap 76. The coupling 95 and the locking mechanism 96 are indicated here only symbolically. The mechanical coupling 95 releases the locking mechanism 96 only when the locking ring 30 is correctly mounted on the support stub 27. Otherwise, the battery door 76 is blocked by the lock mechanism 96 so that it can not be closed. When the battery door 76 is open, however, again a circuit that ensures the power supply of the hearing aid 1, interrupted, and the hearing aid 1 can not be operated.

In beiden Ausführungsformen (gemäß Fig. 4 und Fig. 5) wird der Anwender veranlasst, den korrekten Sitz des Sicherungsrings 30 zu prüfen, wenn das Hörgerät 1 nicht ordnungsgemäß funktioniert.In both embodiments (according to Fig. 4 and Fig. 5 ), the user is caused to check the correct fit of the locking ring 30 when the hearing aid 1 is not functioning properly.

In einer Weiterbildung der in Fig. 4 gezeigten Ausführungsform dienen das Kontaktelement 91 und die Unterbrechung 92 dafür, den Sicherungsring 30 als einen Ein- / Ausschalter für das Hörgerät 1 zu verwenden. Dem Sicherungsring 30 kommt somit als Zusatzfunktion eine Schaltfunktion zu. In einer alternativen (hier nicht dargestellten Ausführungsform) ist der Sicherungsring 30 dabei nicht auf den Haltestutzten 27 aufgeschraubt, sondern mit einer Klickverbindung aufgesteckt, so dass der Sicherungsring 30 rotierbar gelagert ist. Das Kontaktelement 91 überbrückt dabei nur in einer bestimmten Drehstellung des Sicherungsrings 30 die Unterbrechung 92. (Das Kontaktelement 91 erstreckt sich in diesem Fall nur über einen bestimmten Umfangsabschnitt des Sicherungsrings 30.)In a further development of in Fig. 4 In the embodiment shown, the contact element 91 and the interruption 92 serve to use the securing ring 30 as an on / off switch for the hearing aid 1. The locking ring 30 thus comes as an additional function to a switching function. In an alternative (here not shown embodiment), the securing ring 30 is not screwed onto the holding stubs 27, but plugged with a click connection, so that the securing ring 30 is rotatably mounted. The contact element 91 bridges the interruption 92 only in a certain rotational position of the securing ring 30. (The contact element 91 extends in this case only over a certain peripheral portion of the securing ring 30.)

Optional ist der Sicherungsring als 30 als Bedienelement zum Wechsel zwischen unterschiedlichen Hörgerätemodi, etc. eingesetzt.Optionally, the retaining ring 30 is used as an operating element for changing between different hearing device modes, etc.

Die Schaltfunktion des Sicherungsrings 30 ist beispielsweise durch einen spritzgegossenen Schaltungsträger ("Molded Interconnect Device", kurz MID) oder durch einen Reedschalter (auch Reed-Kontakt) - d.h. durch einen durch ein Magnetfeld betätigbaren Schalter - realisiert.The switching function of the locking ring 30 is, for example, by an injection-molded circuit carrier ("Molded Interconnect Device", short MID) or by a reed switch (also reed contact) -. by a switch actuated by a magnetic field - implemented.

Fig. 6 zeigt den Sicherungsring 30 in einer alternativen Ausführungsform, die weitgehend den vorstehenden Ausführungsformen entspricht. Im Unterschied zu den vorstehenden Ausführungsformen ist hier jedoch das Verbindungselement 35 an dem Sicherungsring 30 angeordnet. Das Verbindungselement 35 ist ebenfalls im Wesentlichen analog zu den vorstehenden Ausführungsformen ausgebildet und weist insbesondere den Kugelgelenkkopf 52 auf. Bei aufgeschraubtem Sicherungsring 30 fluchtet das Verbindungselement 35 mit dem Schallkanal 62 (wie in Fig. 1 gezeigt). Fig. 6 shows the locking ring 30 in an alternative embodiment, which largely corresponds to the preceding embodiments. In contrast to the above embodiments, however, the connecting element 35 is arranged on the securing ring 30 here. The connecting element 35 is also designed substantially analogously to the above embodiments and has, in particular, the ball joint head 52. When the securing ring 30 is screwed on, the connecting element 35 is aligned with the sound channel 62 (as in FIG Fig. 1 shown).

In der dargestellten Ausführungsform ist das Verbindungselement 35 aus Metall gefertigt und in einem Spritzgussprozess in den - aus Kunststoff hergestellten - Sicherungsring 30 eingebettet.In the illustrated embodiment, the connecting element 35 is made of metal and embedded in an injection molding process in the - made of plastic - locking ring 30.

Alternativ sind Verbindungselement 35 und Sicherungsring 30 einstückig (monolithisch) gefertigt, beispielsweise als Spritzgussteil aus Kunststoff oder als Drehteil aus Metall.Alternatively, connecting element 35 and securing ring 30 are produced in one piece (monolithic), for example as an injection molded part made of plastic or as a turned part made of metal.

Optional ist in einer Ausführungsform in den Sicherungsring 30 ein Cerumen-Filter integriert (hier nicht dargestellt), der ein Eindringen von Schmutz, insbesondere Cerumen (Ohrenschmalz) in den Schallkanal 62 verhindert.Optionally, in one embodiment, a cerumen filter is integrated in the securing ring 30 (not shown here), which prevents penetration of dirt, in particular cerumen (earwax) into the sound channel 62.

Die Erfindung wird an den vorstehend beschriebenen Ausführungsbeispielen besonders deutlich, ist auf diese Ausführungsbeispiele gleichwohl aber nicht beschränkt. Vielmehr können weitere Ausführungsformen der Erfindung aus den Ansprüchen und der vorstehenden Beschreibung abgeleitet werden. Insbesondere sind die Eigenschaften und Merkmale der vorstehend beschriebenen Ausführungsformen auch auf andere Hörgerätetypen, insbesondere auf ein (BTE/RIC)-Hörgerät übertragbar.The invention will be particularly apparent in the embodiments described above, is nevertheless not limited to these embodiments. Rather, other embodiments of the invention may be derived from the claims and the foregoing description. In particular, the characteristics and features of the embodiments described above can also be applied to other types of hearing aids, in particular to a (BTE / RIC) hearing aid.
