Description

Die vorliegende Erfindung betrifft eine Hörvorrichtung mit einem Gehäuse einschließlich eines Gehäuseinnenraums, in dem Signalverarbeitungskomponenten untergebracht sind, und einem Batteriefach, das in oder an dem Gehäuse befestigt ist und das einen Batteriefachinnenraum aufweist, in den eine Batterie zur Energieversorgung der Hörvorrichtung einsetzbar ist. Unter einer Hörvorrichtung wird hier jedes im/am Ohr oder am Kopf tragbare Schall ausgebende Gerät verstanden, insbesondere ein Headset, ein Hörgerät, Kopfhörer und dergleichen.The present invention relates to a hearing device having a housing including a housing interior, are housed in the signal processing components, and a battery compartment, which is fixed in or on the housing and having a battery compartment interior into which a battery for powering the hearing device is used. A hearing device is understood here to mean any sound-emitting device which can be worn in / on the ear or on the head, in particular a headset, a hearing aid, 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. Die beispielhaft aufgeführten Hörgeräte werden am Außenohr oder im Gehörgang getragen. Darüber hinaus stehen auf dem Markt aber auch Knochenleitungshörhilfen, implantierbare oder vibrotaktile Hörhilfen zur Verfügung. Dabei erfolgt die Stimulation des geschädigten Gehörs entweder mechanisch oder elektrisch.Hearing aids are portable hearing aids that are used to care for the hearing impaired. In order to meet the numerous individual needs, different types of hearing aids such as behind-the-ear hearing aids (BTE), hearing aid with external receiver (RIC: receiver in the canal) and in-the-ear hearing aids (IDO), e.g. Concha hearing aids or canal hearing aids (ITE, CIC). The hearing aids listed by way of example are worn on the outer ear or in the ear canal.

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 Energieversorgung 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. In a hearing aid housing 1 for Carrying behind the ear, one or more microphones 2 are installed for recording the sound from the environment. A signal processing unit 3, which is also integrated in the hearing aid housing 1, processes the microphone signals and amplifies them. The output signal of the signal processing unit 3 is transmitted to a loudspeaker or earpiece 4, which outputs an acoustic signal. The sound is optionally transmitted via a sound tube, which is fixed with an earmold in the ear canal, to the eardrum of the device carrier. The power supply of the hearing device and in particular the signal processing unit 3 is effected by a likewise integrated into the hearing aid housing 1 battery. 5

Hörgeräte sind sehr empfindliche Geräte, die jedoch verhältnismäßig aggressiven Umgebungen ausgesetzt sein können. Hierbei ist nicht nur an hohe Luftfeuchtigkeit zu denken, sondern auch an den Schweiß, den ein Hörgerätträger abgibt, sowie aggressivere Gase und Dämpfe, denen Hörgeräteträger hin und wieder ausgesetzt sind. Derart aggressive Umgebungsbedingungen führen häufig zu Korrosionen von elektrischen Komponenten des Hörgeräts. Daher wurden bislang entsprechende Formen und Beschichtungen von Hörgerätegehäusen vorgeschlagen, um aggressive Substanzen vom Eindringen in das Hörgerätegehäuse abzuhalten.Hearing aids are very sensitive devices, but they may be exposed to relatively aggressive environments. Not only high humidity but also the sweat emitted by a hearing aid wearer, as well as more aggressive gases and vapors, are now and then exposed to hearing aid wearers. Such aggressive environmental conditions often lead to corrosion of electrical components of the hearing aid. Therefore, hitherto corresponding forms and coatings of hearing aid housings have been proposed to prevent aggressive substances from entering the hearing aid housing.

Aus der Druckschrift DE 199 03 090 A1 ist ein wasserdichtes Hör-Behandlungsgerät bekannt. Es umfasst ein Gehäuse mit Batteriefach sowie einer Schallaustrittsöffnung. Das Batteriefach ist gegenüber dem übrigen Gehäuse wasserdicht abgedichtet. Die Schallaustrittsöffnung ist durch eine akustisch durchlässige, wasserdichte Folie abgedichtet.From the publication DE 199 03 090 A1 is a waterproof hearing treatment device known. It includes a housing with battery compartment and a sound outlet. The battery compartment is watertight sealed from the rest of the housing. The sound outlet is sealed by an acoustically permeable, waterproof film.

Aus der Druckschrift DE 195 02 994 C2 ist eine ebenfalls wasserdichte Höfhilfe bekannt, die ein Gehäuse mit Belüftungsöffnung umfasst. Eine Wasserabdichtungseinrichtung versperrt die Belüftungsöffnung und dient dazu, Luft einzulassen, das Eindringen von Feuchtigkeit jedoch zu verhindern.From the publication DE 195 02 994 C2 a likewise waterproof Höfhilfe is known which comprises a housing with ventilation opening. A water seal device obstructs the ventilation opening and serves to admit air, but to prevent the ingress of moisture.

Vielfach werden heute Hörgeräte mit Zink-Luft-Batterien betrieben. Vor dem Einsatz dieser Zink-Luft-Batterien werden die Luftlöcher auf der Oberseite des Batteriegehäuses mit einem Klebeband verschlossen. Dies verhindert, dass Luft, insbesondere Sauerstoff, aus der Umgebung mit dem Zink der Batterie reagiert. Dieser Typ von nicht ladbarer, elektrochemischer Batterie erzeugt nämlich die elektrische Energie durch Oxidation von Zink mit dem Sauerstoff von Luft.In many cases today hearing aids are operated with zinc-air batteries. Before using these zinc-air batteries, the air holes on the top of the battery case are sealed with tape. This prevents air, especially oxygen, from the environment from reacting with the zinc of the battery. Namely, this type of non-chargeable electrochemical battery generates the electrical energy by oxidation of zinc with the oxygen of air.

Wenn der Hörgeräteträger die Batterie in seinem Hörgerät benutzen will, wird er zunächst den Klebestreifen von der Zink-Luft-Batterie entfernen. Sobald der Klebestreifen, abgenommen ist, wird Sauerstoff in die Luftlöcher der Batterie eindringen. Der Luftsauerstoff, der bei der Reaktion als Katode wirkt, wird mit der wässrigen Zinkanode in der Batterie reagieren. Aus der Reaktion ergeben sich entsprechende elektrische Ladungen.If the hearing aid user wants to use the battery in his hearing aid, he will first remove the adhesive strip from the zinc-air battery. Once the tape is removed, oxygen will penetrate into the air holes of the battery. The atmospheric oxygen, which acts as a cathode in the reaction, will react with the aqueous zinc anode in the battery. The reaction results in corresponding electrical charges.

Nicht selten kommt es zu weißen, puderigen Ablagerungen auf der Zink-Luft-Batterie, die aus den Luftlöchern der Batterie stammen. Diese Ablagerungen sind auf das Elektrolytmaterial Kaliumhydroxid (KOH) in der Batterie zurückzuführen. KOH ist in Verbindung mit Wasserdampf und Wasser sehr mobil und ist relativ aggressiv insbesondere gegenüber Leichtmetallen.Not infrequently, there are white, powdery deposits on the zinc-air battery, which come from the air holes of the battery. These deposits are due to the electrolyte material potassium hydroxide (KOH) in the battery. KOH is very mobile in conjunction with water vapor and water and is relatively aggressive, especially against light metals.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, Schaltelemente einer Hörvorrichtung auf einfache Art vor Korrosion zu schützen.The object of the present invention is thus to protect switching elements of a hearing device in a simple manner from corrosion.

Erfindungsgemäß wird die Aufgabe gelöst durch eine Hörvorrichtung mit einem Gehäuse einschließlich eines Gehäuseinnenraums, in dem Signalverarbeitungskomponenten untergebracht sind, und einem Batteriefach, das in oder an dem Gehäuse befestigt ist und das einen Batteriefachinnenraum aufweist, in den eine Batterie zur Energieversorgung der Hörvorrichtung einsetzbar ist, sowie mit einer Membran, die den Gehäuseinnenraum von dem Batteriefachinnenraum trennt.According to the invention the object is achieved by a hearing device having a housing including a housing interior, are accommodated in the signal processing components, and a battery compartment which is fixed in or on the housing and having a battery compartment interior into which a battery for powering the hearing device is used, and with a membrane that separates the housing interior from the battery compartment interior.

In vorteilhafter Weise kann durch die Membran verhindert werden, dass aggressive, von einer Batterie stammende Substanzen in den Innenraum einer Hörvorrichtung bzw. eines Hörgeräts gelangen und dort zu Korrosion von Elektronikkomponenten oder anderen Elementen führen. Insbesondere kann die Membran Ausfällungen, die durch Undichtigkeiten der Batterie entstehen, aus der Luft ausfiltern bzw. am Fließen hindern. So können insbesondere der Verstärker aber auch elektromechanische Komponenten wie Hörer, Mikrofone, Schalter und dergleichen vor Korrosion geschützt werden.Advantageously, it can be prevented by the membrane that aggressive, originating from a battery substances reach the interior of a hearing device or a hearing aid and there lead to corrosion of electronic components or other elements. In particular, the membrane precipitates resulting from leaks in the battery, filter out of the air or prevent it from flowing. Thus, in particular the amplifier but also electromechanical components such as handset, microphones, switches and the like can be protected from corrosion.

Vorzugsweise ist die Membran in der Hörvorrichtung austauschbar befestigt. Damit ist es möglich, beispielsweise beim Batteriewechsel auch die Membran zu wechseln, die mit aggressiven Substanzen gefüllt bzw. gesättigt ist.Preferably, the membrane is mounted interchangeably in the hearing device. This makes it possible, for example when changing the battery, to change the membrane which is filled or saturated with aggressive substances.

Des Weiteren kann das Batteriefach in das Gehäuse einschwenkbar sein. Ein derartiges Batteriefach ermöglicht einen komfortablen Austausch der Batterie.Furthermore, the battery compartment can be pivoted into the housing. Such a battery compartment allows a comfortable replacement of the battery.

In einer speziellen Ausführungsform kann die Membran in oder an dem Gehäuse befestigt sein. Dies hat den Vorteil, dass die Membran beim Austausch einer Batterie kaum verletzt werden kann.In a specific embodiment, the membrane may be fixed in or on the housing. This has the advantage that the membrane can hardly be injured when replacing a battery.

Speziell kann das Gehäuse einen Rahmen aufweisen und die Membran an dem Rahmen befestigt sein. Damit bleibt die Schutzfunktion der Membran erhalten, auch wenn beispielsweise die am Rahmen befestigten Gehäuseschalen ausgetauscht werden.Specifically, the housing may have a frame and the membrane may be attached to the frame. This preserves the protective function of the membrane, even if, for example, the housing shells attached to the frame are replaced.

Bei einer alternativen Ausführungsform ist die Membran in oder am Batteriefach befestigt. Vorteilhaft an dieser Ausgestaltung ist, dass die Membran beispielsweise beim Herausdrehen bzw. Herausschieben des Batteriefachs leicht ausgetauscht werden kann, da sie dann ohne weiteres zugänglich ist.In an alternative embodiment, the membrane is mounted in or on the battery compartment. An advantage of this configuration is that the membrane can be easily replaced, for example, when unscrewing or pushing out of the battery compartment, as it is then readily accessible.

Ferner kann die Membran weich und formbar sein. Dies wirkt sich insbesondere dann günstig aus, wenn die Membran hinter Vorsprüngen in dem Gehäuse bzw. Batteriefach einzubauen ist.Furthermore, the membrane may be soft and moldable. This has a favorable effect in particular when the membrane is to be installed behind projections in the housing or battery compartment.

Speziell sollte die Membran säurebeständig sein. Hierunter wird insbesondere auch verstanden, dass die Membran beständig gegenüber Kalilauge, also der wässrigen Lösung von Kaliumhydroxid ist. Weiterhin ist es günstig, wenn die Membran hydrophil ist. Eine derartige Membran kann dazu beitragen, dass die Luft im Hörgerät bzw. in der Hörvorrichtung entfeuchtet wird.Specifically, the membrane should be acid resistant. By this is meant in particular also that the membrane is resistant to potassium hydroxide solution, ie the aqueous solution of potassium hydroxide. Furthermore, it is advantageous if the membrane is hydrophilic. Such a membrane can contribute to the dehumidification of the air in the hearing device or in the hearing device.

Die vorliegende Erfindung wird anhand der beigefügten Zeichnungen näher erläutert, in denen zeigen:

  • FIG 1 den schematischen Aufbau eines Hörgeräts gemäß dem Stand der Technik;
  • FIG 2 die Ansicht eines HdO-Hörgeräts von der Unterseite gemäß einer ersten Ausführungsform und
  • FIG 3 die Ansicht eine HdO-Hörgeräts von der Unterseite gemäß einer zweiten Ausführungsform.
The present invention will be further explained with reference to the accompanying drawings, in which:
  • FIG. 1 the schematic structure of a hearing aid according to the prior art;
  • FIG. 2 the view of a BTE hearing aid from the bottom according to a first embodiment and
  • FIG. 3 the view of a BTE hearing aid from the bottom according to a second embodiment.

Die nachfolgend näher geschilderten Ausführungsbeispiele stellen bevorzugte Ausführungsformen der vorliegenden Erfindung dar.The embodiments described in more detail below represent preferred embodiments of the present invention.

In FIG 2 ist ein Teil eines HdO-Hörgeräts mit geöffnetem Batteriefach 10 dargestellt. Das Batteriefach 10 ist schwenkbar an dem Rahmen 11 befestigt. Ebenfalls an dem Rahmen 11 sind Gehäuseschalenteile 12 befestigt. Durch das Gehäuse, im vorliegenden Fall der Gehäuserahmen 11 und Gehäuseschalen 12, ergibt sich ein Gehäuseinnenraum, in dem Elektronikkomponenten wie Verstärker, Hörer, Mikrofone, Schalter und dergleichen angeordnet sind. Außerdem ist in FIG 2 ein Batteriekontakt 13 im Gehäuse des Hörgeräts sowie ein Schalter 14 außen am Gehäuse zu erkennen.In FIG. 2 is a part of a BTE hearing aid with the battery compartment 10 is shown. The battery compartment 10 is pivotally attached to the frame 11. Also on the frame 11 housing shell parts 12 are attached. Through the housing, in the present case, the housing frame 11 and housing shells 12, there is a housing interior in which electronic components such as amplifiers, headphones, microphones, switches and the like are arranged. It is also in FIG. 2 a battery contact 13 in the housing of the hearing aid and a switch 14 outside the housing to recognize.

Das schwenkbare Batteriefach 10 besitzt einen Batteriefachinnenraum 15, in den eine Batterie eingesetzt werden kann. An der dem Gehäuseinnenraum zugewandten Seite des Batteriefachs ist eine Membran 16 angebracht. Sie ist hier etwa halbkreisförmig ausgebildet und schließt den Batteriefachinnenraum 15 soweit wie möglich von dem Gehäuseinnenraum im geschlossenen Zustand des Batteriefachs 10 ab. Hierzu ist die Membran 16 etwa genauso breit wie das Batteriefach 10. D. h. die Erstreckung der Membran 16 in axialer Richtung des Batteriefachs 10 entspricht in etwa der axialen Erstreckung des zylinderförmigen Batteriefachs.The pivotable battery compartment 10 has a battery compartment interior 15 into which a battery can be inserted. At the housing interior facing side of the battery compartment, a membrane 16 is attached. It is designed here approximately semicircular and closes the battery compartment interior 15 as far as possible from the housing interior in the closed state of the battery compartment 10. For this purpose, the membrane 16 is about as wide as the battery compartment 10. D. h. the extent of the membrane 16 in the axial direction of the battery compartment 10 corresponds approximately to the axial extent of the cylindrical battery compartment.

Der Zweck der Membran 16 ist das Aufnehmen bzw. Ausfiltern von aggressiven Substanzen, die die Batterie verlassen und beispielsweise durch einen Luftstrom in den Gehäuseinnenraum gelangen könnten. Daher ist das Material der Membran so gewählt, dass es säure- bzw. laugenbeständig ist. Insbesondere ist sie in der Lage, Ausscheidungen der Batterie aufzunehmen, zu binden und gegebenenfalls chemisch umzusetzen.The purpose of the membrane 16 is the picking or filtering out of aggressive substances that could leave the battery and could get into the housing interior, for example by an air flow. Therefore, the material of the membrane is chosen so that it is acid or alkali resistant. In particular, it is able to absorb precipitates of the battery, to bind and, if necessary, to react chemically.

Weiterhin kann die Membran 16 weich und leicht formbar ausgebildet sein. Dadurch lässt sie sich leicht an Teile des Batteriefachs anlegen. Speziell können für die Membran 16 beispielsweise Bismaleimid-Polymere verwendet werden, die sich durch exzellente Lösungsmittelbeständigkeit auszeichnen. Ebenso können Polyethersulfon-Membranen eingesetzt werden, wenn hydrophile Eigenschaften im Vordergrund stehen und Partikel ausgefiltert werden sollen.Furthermore, the membrane 16 may be formed soft and easily moldable. This makes it easy to put on parts of the battery compartment. Specifically, for the membrane 16, for example, bismaleimide polymers can be used, which are characterized by excellent solvent resistance. Likewise, polyethersulfone membranes can be used if hydrophilic properties are in the foreground and particles are to be filtered out.

Wie bereits angedeutet wurde, lässt sich die Membran 16 leicht austauschen. Dies liegt nicht nur am Membranmaterial sondern auch an der Tatsache, dass die Membran 16 an dem ausschwenkbaren Batteriefach 10 befestigt ist. Durch das Aufschwenken des Batteriefachs 10 wird derjenige Teil des Batteriefachs, der im eingeschwenkten Zustand sich im Gehäuse befindet, nach außen geschwenkt. Da auf diesem nach außen schwenkbaren Teil des Batteriefachs die Membran 16 sitzt, ist sie im aufgeschwenkten Zustand des Batteriefachs leicht zugänglich.As already indicated, the membrane 16 can be easily replaced. This is due not only to the membrane material but also to the fact that the membrane 16 is attached to the swing-out battery compartment 10. By pivoting the battery compartment 10 of that part of the battery compartment, which is in the swung-in state in the housing, pivoted outwardly. Since on this outwardly pivotable part of the battery compartment, the membrane 16 is seated, is they easily accessible in the pivoted state of the battery compartment.

FIG 3 zeigt eine weitere Ausführungsform der vorliegenden Erfindung. Insbesondere handelt es sich bei FIG 3 ebenfalls um eine Ansicht eines Unterteils eines HdO-Hörgeräts. Dieses Hörgerät besitzt im Wesentlichen die gleichen Komponenten wie das von FIG 2, weshalb größtenteils die gleichen Bezugszeichen verwendet sind. Insbesondere sind ebenfalls zu erkennen: ein aufschwenkbares Batteriefach 10, ein Rahmen 11, Gehäuseschalen 12, ein Batteriekontakt 13, ein Schalter 14 und ein Batterieinnenraum 15. Bei diesem Ausführungsbeispiel ist jedoch eine Membran 17 nicht direkt am Batteriefach 10, sondern im Gehäuse bzw. am Rahmen 11 angebracht. Diese Membran 17 befindet sich an einem Ort, an dem das Batteriefach innerhalb des Gehäuses in seinem eingeschwenkten Zustand endet. Sie verschließt somit den Gehäuseinnenraum, in dem sich insbesondere Verstärker, Hörer, Mikrofone und dergleichen befinden, nach außen auch im aufgeschwenkten Zustand des Batteriefachs 10. Diese Ausführungsform schützt die Membran 17 also den Gehäuseinnenraum nicht nur gegenüber aggressiven Substanzen der Batterie, sondern auch gegenüber Umwelteinflüssen von außen. FIG. 3 shows a further embodiment of the present invention. In particular, it is with FIG. 3 also a view of a lower part of a BTE hearing aid. This hearing aid has substantially the same components as that of FIG. 2 , which is why most of the same reference numerals are used. In particular, can also be seen: a swing-open battery compartment 10, a frame 11, housing shells 12, a battery contact 13, a switch 14 and a battery compartment 15. In this embodiment, however, a membrane 17 is not directly on the battery compartment 10, but in the housing or on Frame 11 attached. This membrane 17 is located at a location where the battery compartment terminates within the housing in its pivoted state. It thus closes off the interior of the housing, in which in particular amplifiers, receivers, microphones and the like are located, even when the battery compartment 10 is pivoted outwards. This embodiment thus protects the diaphragm 17 not only against aggressive substances in the battery, but also against environmental influences from the outside.

Die Membran 17 ist ansonsten wie die Membran 16 aus dem vorhergehenden Beispiel gemäß FIG 2 ausgebildet, insbesondere was das Material betrifft. Daher ergeben sich die Vorteile der Membran 16 auch hier für die Membran 17.The membrane 17 is otherwise the same as the membrane 16 of the previous example FIG. 2 trained, especially as regards the material. Therefore, the advantages of the membrane 16 also arise here for the membrane 17th
