Description

Die vorliegende Erfindung betrifft eine Hörvorrichtung mit einem Hörer, der ein Hörergehäuse aufweist, und einer elektrischen Spule, die unmittelbar auf einem Abschnitt des Hörgehäuses befestigt ist. Unter einer Hörvorrichtung wird hier insbesondere ein Hörgerät, ein Headset, ein Kopfhörer oder dergleichen verstanden.The present invention relates to a hearing device with a receiver, which has a receiver housing, and an electrical coil, which is mounted directly on a portion of the hearing housing. A hearing device is understood to mean in particular a hearing aid, a headset, a headphone or 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) und In-dem-Ohr-Hörgeräte (IdO), z.B. auch Concha-Hörgeräte oder Kanal-Hörgeräte (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) and in-the-ear hearing aids (ITO), e.g. also Concha hearing aids or canal hearing aids (CIC), provided. The hearing aids listed by way of example are worn on the outer ear or in the ear canal. In addition, bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.

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.

Hörer bzw. Lautsprecher in Hörgeräten arbeiten in der Regel nach dem elektrodynamischen Prinzip. Das dabei erzeugte magnetische Feld kann nicht vollständig genutzt werden und geht zum Teil als Störfeld an die Umgebung verloren. Diese ungewollte "magnetische Abstrahlung" gilt es abzuschirmen. Andernfalls stört das Magnetfeld des Hörers beispielsweise die in das Hörgerät eingebaute Telefonspule.Handset or loudspeakers in hearing aids generally work according to the electrodynamic principle. The generated magnetic field can not be fully utilized and is partly lost as an interference field to the environment. This unwanted "magnetic radiation" is to shield it. Otherwise, the listener's magnetic field disturbs, for example, the telecoil built into the hearing aid.

Um das Klirren bei Telefonspulenanwendungen möglichst gering zu halten und die entsprechenden Normen bezüglich der elektromagnetischen Interferenzen (EMI) einzuhalten, werden beispielsweise sogenannte Mu-Metallbleche eingesetzt, die das Magnetfeld eines Hörers nach außen abschirmen. Außerdem ist bekannt, die Verstärker von Hörgeräten mit Kompensationsspulen auszustatten, um ebenfalls die magnetische Abstrahlung der Hörer zu reduzieren.In order to keep the clinking in telecoil applications as low as possible and to comply with the corresponding standards for electromagnetic interference (EMI), for example, so-called Mu-metal sheets are used, which shield the magnetic field of a listener to the outside. It is also known to equip the amplifier hearing aids with compensation coils, also to reduce the magnetic radiation of the listener.

Weiterhin ist aus der Druckschrift US 2004/0028251 A1 eine raumsparende Antennenanordnung für Hörgeräte bekannt. Dabei wird die Antennenspule um das Hörergehäuse gewickelt. Das Hörergehäusematerial bildet praktisch den Kern der Spule. Voraussetzung dafür, dass die Hörerspule die Antennen- bzw. Telefonspule nicht stört, ist, dass das Hörergehäuse magnetisch dicht ist. Dies bedeutet, dass das von der Hörerspule erzeugte Magnetfeld nicht nach außen zur Antennenspule gelangen darf. Eine vollständige Entkopplung beider Spulen ist jedoch nur schwer zu erreichen. Die um das Hörergehäuse gewickelte Spule dient nicht nur als Antennenspule, sondern kann gleichzeitig als Kompensationsspule verwendet werden. Hierzu besitzt die Spule mehrere Abgriffe. Damit entsteht jedoch ein sehr komplexes Bauteil, und ein Austausch des Hörers ist beispielsweise immer auch mit einem Austausch der Antennenspule verbunden.Furthermore, from the document US 2004/0028251 A1 a space-saving antenna arrangement for hearing aids known. The antenna coil is wound around the receiver housing. The earphone housing material virtually forms the core of the coil. The precondition for the fact that the receiver coil does not disturb the antenna or telecoil coil is that the receiver housing is magnetically tight. This means that the magnetic field generated by the receiver coil must not go outside to the antenna coil. However, complete decoupling of both coils is difficult to achieve. The coil wound around the receiver housing not only serves as an antenna coil, but can also be used as a compensation coil. Owns for this the coil has several taps. However, this creates a very complex component, and an exchange of the handset, for example, always connected to an exchange of the antenna coil.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, einen einfach aufgebauten Hörer mit einer wirksamen magnetischen Abschirmung vorzuschlagen.The object of the present invention is therefore to propose a simply constructed handset with an effective magnetic shielding.

Erfindungsgemäß wird diese Aufgabe gelöst durch eine Hörvorrichtung mit einem Hörer, der ein Hörergehäuse aufweist, und einer elektrischen Spule, die unmittelbar auf einem Abschnitt des Hörergehäuses befestigt ist, wobei die Hauptachse der elektrischen Spule senkrecht zur Oberfläche des Abschnitts des Hörergehäuses steht und die elektrische Spule mit dem Hörer in Serie geschaltet ist.According to the invention, this object is achieved by a hearing device having a receiver which has a receiver housing, and an electrical coil which is fastened directly to a section of the receiver housing, wherein the main axis of the electrical coil is perpendicular to the surface of the section of the receiver housing and the electric coil is connected in series with the handset.

In vorteilhafter Weise ist es so möglich, einen günstigen Hörer mit wirksamer magnetischer Abschirmung herzustellen. Dabei kann die elektrische Spule auf dem Hörergehäuse so ausgerichtet werden, dass gerade die magnetisch empfindlichen Bauteile in der Hörvorrichtung, z. B. die Telefonspule, abgeschattet werden.Advantageously, it is thus possible to produce a cheap handset with effective magnetic shielding. In this case, the electrical coil can be aligned on the receiver housing so that just the magnetically sensitive components in the hearing, z. As the telecoil, be shadowed.

Vorzugsweise ist die elektrische Spule spiralförmig ausgebildet. Hierdurch kann eine Spule mit geringer Bauhöhe realisiert werden.Preferably, the electric coil is formed spirally. As a result, a coil with a low overall height can be realized.

Die elektrische Spule kann außerdem eine Luftspule sein. Hierdurch wird auf einen Spulenkern verzichtet, der aber in der Regel für die magnetische Abschirmung nicht notwendig ist.The electrical coil may also be an air coil. As a result, dispenses with a coil core, but which is usually not necessary for the magnetic shielding.

Darüber hinaus besitzt die elektrische Spule günstigerweise als Träger ein Polyimidsubstrat. Dieses lässt sich insbesondere als Folie einsetzen. Durch den Folienträger kann der Raumbedarf der elektrischen Spule weiter reduziert werden.In addition, the electric coil desirably has a polyimide substrate as the support. This can be used in particular as a film. By the film carrier, the space requirement of the electric coil can be further reduced.

Das Polyimid sorgt ferner für eine ausreichende elektrische Isolierung und ist außerdem genügend mechanisch robust.The polyimide also provides sufficient electrical insulation and is also sufficiently mechanically robust.

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

FIG 2
den erfindungsgemäßen Aufbau eines Hörer mit einer Kompensationsspule.
The present invention will be further explained with reference to the accompanying drawings, in which:
FIG. 1
the basic structure of a hearing aid according to the prior art and
FIG. 2
the inventive structure of a listener with a compensation coil.

Das nachfolgend näher geschilderte Ausführungsbeispiel stellt eine bevorzugte Ausführungsform der vorliegenden Erfindung dar.The embodiment described in more detail below represents a preferred embodiment of the present invention.

Der in dem Beispiel von FIG 2 dargestellte Hörer 4 besitzt ein Hörergehäuse 10 und einen daran angebrachten Stutzen 11 als Schallauslass. Das Gehäuse 10 ist hier quaderförmig dargestellt kann aber auch beispielsweise zylinderförmig oder in einer anderen beliebigen Form ausgebildet sein. Auch die Kanten und Ecken können abgerundet sein.The one in the example of FIG. 2 illustrated handset 4 has a receiver housing 10 and an attached nozzle 11 as a sound outlet. The housing 10 is shown here cuboid but can also be formed, for example, cylindrical or in any other arbitrary shape. Even the edges and corners can be rounded.

An der dem Stutzen 11 gegenüberliegenden Seite des Hörergehäuses 10 sind Kontakte 12, 13 zur Beschaltung des Hörers 4 angeordnet. Selbstverständlich können diese Kontakte 12, 13 auch an einer anderen Stelle des Hörergehäuses 10 angeordnet sein.At the opposite side of the nozzle 11 of the receiver housing 10 contacts 12, 13 are arranged for wiring the receiver 4. Of course, these contacts 12, 13 may also be arranged at a different location of the receiver housing 10.

In dem Beispiel von FIG 2 ist an der Oberseite des Hörergehäuses 10 eine spiralförmige Luftspule 14 befestigt. Sie ist auf einer Polyimidfolie 15 aufgebracht. Auf der Polyimidfolie 15 befinden sich außerdem Spulenkontakte 16, 17, die mit den beiden Enden der Spule 14 verbunden sind.In the example of FIG. 2 is attached to the top of the receiver housing 10, a spiral-shaped air coil 14. It is applied to a polyimide film 15. On the polyimide film 15 are also coil contacts 16, 17, which are connected to the two ends of the coil 14.

Die Polyimidfolie mit der elektrischen Spule 14 und den Spulenkontakten 16, 17 ist insgesamt flexibel und passt sich an die Oberfläche des Hörergehäuses 10 an. Durch die geringe Bauhöhe der Spule 14 und der Folie 15 entsteht praktisch kein zusätzlicher Raumbedarf für diese Kompensationsspule. Die Polyimidfolie 15, die den Träger der Spule 14 bildet, kann beispielsweise auf dem Hörergehäuse 10 aufgeklebt werden. Damit bedeckt sie einen entsprechenden Abschnitt des Hörergehäuses 10. Insgesamt kann die Größe der Kompensationsspule 14, 15, 16, 17 so gewählt werden, dass gerade eine in einem Hörgerät befindliche Telefonspule von dem Hörer 4 magnetisch abgeschattet wird.The polyimide film with the electrical coil 14 and the coil contacts 16, 17 is flexible overall and adapts to the surface of the receiver housing 10. By the low Height of the coil 14 and the film 15 is virtually no additional space required for this compensation coil. The polyimide film 15, which forms the carrier of the coil 14, can be glued on the receiver housing 10, for example. Overall, the size of the compensation coil 14, 15, 16, 17 are selected so that just located in a hearing aid telephone coil is magnetically shadowed by the handset 4.

Die elektrische Spule 14 erstreckt sich hauptsächlich in einer Ebene parallel zu dem Oberflächenabschnitt des Hörergehäuses, auf den sie aufgebracht ist. Ihre Hauptachse steht senkrecht zu diesem Oberflächenabschnitt. Diese Konstellation kann nicht nur mit einer spiralförmigen Spule, sondern auch z. B. mit einer gewendelten Spule geringer Windungszahl erreicht werden.The electric coil 14 extends mainly in a plane parallel to the surface portion of the receiver housing to which it is applied. Its main axis is perpendicular to this surface section. This constellation can not only with a spiral coil, but also z. B. can be achieved with a coiled coil low number of turns.

Das Wirkungsprinzip der Luftspule 14 besteht darin, dass sie ein das Gegenfeld zum dem Störfeld des Hörers 4 bildet. Hierzu wird sie mit der Hörerspule (in FIG 2 nicht dargestellt) in Serie geschaltet. Dabei ist die Polung der Luftspule 14 zu beachten, damit das von ihr erzeugte Magnetfeld zu dem der Hörerspule entgegengesetzt gerichtet ist. In dem konkreten Beispiel von FIG 2 ist zum Betreiben des Hörers mit der Kompensationsspule daher eine erste Litze 18 an den Hörerkontakt 13 angelötet. Über eine weitere Litze 19 ist der zweite Hörerkontakt 12 mit dem Spulenkontakt 16 verbunden. Schließlich wird noch eine dritte Litze 20 an den zweiten Spulenkontakt 17 angelötet. Die Hörerspule und die Kompensationsspule sind somit in Reihe geschaltet.The principle of operation of the air coil 14 is that it forms the opposite field to the interference field of the receiver 4. For this purpose, she is using the receiver coil (in FIG. 2 not shown) connected in series. In this case, the polarity of the air coil 14 is observed, so that the magnetic field generated by it is directed opposite to that of the earpiece. In the concrete example of FIG. 2 is therefore to operate the handset with the compensation coil a first strand 18 soldered to the handset contact 13. About another strand 19, the second handset contact 12 is connected to the coil contact 16. Finally, a third strand 20 is soldered to the second coil contact 17. The receiver coil and the compensation coil are thus connected in series.

Der besondere Vorteil dieser Kompensation liegt darin, dass sie direkt auf der Störquelle stattfindet. Damit kann ein verhältnismäßig großer Raumwinkel mit einer kleinen Kompensationsspule abgedeckt werden. Der weitere Vorteil, dass die Kompensationsspule sehr klein ist, wurde bereits genannt. Dies ist insbesondere für die In-dem-Ohr-Hörgeräte von großer Bedeutung, da dort nur äußerst wenig Platz zur Verfügung steht.The particular advantage of this compensation is that it takes place directly on the source of interference. Thus, a relatively large solid angle can be covered with a small compensation coil. The further advantage that the compensation coil is very small has already been mentioned. This is especially great for in-the-ear hearing aids Meaning, since there is very little space available.

Ein weiterer Vorteil dieser Art der Kompensation besteht darin, dass jeder Hörer seine eigene Kompensation erhält. Damit ist man unabhängig vom Hörgeräteverstärker, auf dem vielfach Kompensationsspulen angeordnet wurden. Dieser Vorteil kommt zum Tragen, wenn beispielsweise zwei Hersteller als Hörerlieferanten eingesetzt werden.Another advantage of this type of compensation is that each listener receives its own compensation. This makes you independent of the hearing aid amplifier, on which often compensation coils have been arranged. This advantage comes into play when, for example, two manufacturers are used as handset suppliers.

Als weiterer Vorteil ist schließlich zu nennen, dass kein Mu-Metall mehr in der Hörvorrichtung, bzw. dem Hörgerät eingebaut werden muss. Damit reduzieren sich die Herstellungskosten. Falls es jedoch zur Verbesserung der Abschirmung erwünscht oder erforderlich ist, kann die auf dem Hörergehäuse montierte erfindungsgemäße Kompensationsspule auch mit einem Mu-Metall und einer oder mehreren Kompensationsspulen auf dem Verstärker kombiniert werden.Finally, another advantage is that no Mu metal has to be installed in the hearing device or the hearing aid. This reduces the production costs. However, if it is desired or necessary to improve shielding, the compensation coil of the present invention mounted on the receiver housing may also be combined with a mu-metal and one or more compensation coils on the amplifier.
