Description

Die vorliegende Erfindung betrifft ein Hörgerät mit einem Gehäuse zur Aufnahme von internen Elektronikkomponenten, einer außerhalb des Gehäuses angeordneten externen Elektronikkomponente und einer Verbindungseinrichtung zum mechanischen und elektrischen Verbinden des Gehäuses und mindestens einer der internen Elektronikkomponenten mit der externen Elektronikkomponente.The present invention relates to a hearing aid with a housing for receiving internal electronic components, an external electronic component arranged outside the housing and a connecting device for mechanical and electrical connection of the housing and at least one of the internal electronic components with the external electronic component.

Es besteht der Bedarf, an ein Hörgerät externe Elektronikkomponenten anzuschließen. Beispiele für diese externen Elektronikkomponenten sind Hörer, externe Mikrofone oder Mikrofonarrays, Kabel für Crossverbinder zu einem zweiten Hörgerät, Funkempfänger und dergleichen. Der bislang häufigste Anwendungsfall ist die Verbindung des Hörgeräts mit einem externen Hörer. Aus Gründen der Rückkopplung oder des Platzbedarfs kann es notwendig sein, einen externen Hörer für das Hörgerät vorzusehen.There is a need to connect external electronic components to a hearing aid. Examples of these external electronic components are earphones, external microphones or microphone arrays, cables for cross connectors to a second hearing device, radio receiver and the like. The most common application to date is the connection of the hearing aid to an external handset. For reasons of feedback or space requirements, it may be necessary to provide an external handset for the hearing aid.

Bislang sind Hörgeräte mit externem Hörer bekannt, bei denen die Verbindung zwischen Hörgerät und Hörer vom Akustiker nicht lösbar ist. Der Grund hierfür liegt darin, dass die elektrischen Versorgungsleitungen für den Hörer an das Hörgerät angelötet sind. Die elektrischen Verbindungsleitungen werden bei einer bekannten Variante durch einen Tragehaken und weiter durch einen biegsamen Formschlauch geführt. Eine gewisse individuelle Längenanpassung ist dadurch möglich, dass der Formschlauch in dem Tragehaken verschiebbar ist. Bei mechanischer Beanspruchung kann sich jedoch der Formschlauch aus dem Tragehaken lösen, so dass sich die eingestellte Länge verändert.Hearing aids with an external handset are known so far, in which the connection between the hearing aid and the handset cannot be released by the acoustician. The reason for this is that the electrical supply lines for the listener are soldered to the hearing aid. In a known variant, the electrical connecting lines are guided through a carrying hook and further through a flexible molded hose. A certain individual length adjustment is possible in that the molded hose can be moved in the carrying hook. With mechanical stress, however, the molded hose can come loose from the carrying hook, so that the set length changes.

Bei anderen Hörgeräten wird der externe Hörer mittels eines Steckverbinders an das Hörgerät angeschlossen. Da die elektrischen Verbindungsleitungen konfektioniert sind, ist hier eine individuelle Längenanpassung nicht möglich.With other hearing aids, the external handset is connected to the hearing aid by means of a plug connector. Because the electrical Connection cables are assembled, an individual length adjustment is not possible here.

Für die Verbesserung von Hörgeräten sind stets die Gewohnheiten der Hörgeräteträger zu berücksichtigen. So ist es hinsichtlich der mechanischen Verbindung zwischen externem Hörer und Hörgerät notwendig zu beachten, dass der Hörgeräteträger ein Ohrpassstück (Otoplastik) am Schlauch aus dem Ohr zieht. Daher muss die mechanische Verbindung zwischen dem Schlauch beziehungsweise Kabel und dem Ohrpassstück aber auch die Verbindung zwischen dem Kabel und dem Hörgerät für eine entsprechende mechanische Beanspruchung ausgelegt sein.The habits of the hearing aid wearer must always be taken into account when improving hearing aids. With regard to the mechanical connection between the external earpiece and the hearing aid, it is necessary to ensure that the hearing aid wearer pulls an earmold (otoplastic) on the tube out of the ear. Therefore, the mechanical connection between the tube or cable and the earmold but also the connection between the cable and the hearing aid must be designed for a corresponding mechanical stress.

In diesem Zusammenhang ist aus der Druckschrift DE 195 41 648 A1 ein Hörhilfegerät bekannt, dem ein mobiles Sende- und Empfangsmodul zugeordnet ist. Das mobile Sende- und Empfangsmodul weist Kontaktelemente auf und ist mit entsprechenden Gegenkontakten des Hörhilfegeräts koppelbar. Gemäß einer weiteren Ausgestaltung ist das mobile Sende- und Empfangsmodul über eine Verdrahtung an das Hörhilfegerät anschließbar.In this context, a hearing aid device is known from the publication DE 195 41 648 A1, to which a mobile transmitting and receiving module is assigned. The mobile transmitting and receiving module has contact elements and can be coupled to corresponding counter-contacts of the hearing aid. According to a further embodiment, the mobile transmitting and receiving module can be connected to the hearing aid device via wiring.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine leicht handhabbare elektrische und mechanische Verbindung vom Hörgerät zu einer externen Elektronikkomponente bereitzustellen.The object of the present invention is to provide an easily manageable electrical and mechanical connection from the hearing aid to an external electronic component.

Erfindungsgemäß wird diese Aufgabe gelöst durch ein Hörgerät mit einem Gehäuse zur Aufnahme von internen Elektronikkomponenten, einer außerhalb des Gehäuses angeordneten externen Elektronikkomponente und einer Verbindungseinrichtung zum mechanischen und elektrischen Verbinden des Gehäuses und zumindest einer der internen Elektronikkomponenten mit der externen Elektronikkomponente, wobei die Verbindungseinrichtung eine Schneidklemme, die an dem Gehäuse oder der externen Elektronikkomponente angeordnet ist, oder mindestens zwei Schneidklemmen, von denen eine an dem Gehäuse und eine zweite an der externen Elektronikkomponente angeordnet sind, und ein Verbindungskabel, das in die eine Schneidklemme oder die mindestens zwei Schneidklemmen unter Herstellung einer elektrischen und mechanischen Verbindung einklemmbar ist, aufweist.According to the invention, this object is achieved by a hearing aid with a housing for receiving internal electronic components, an external electronic component arranged outside the housing and a connecting device for mechanically and electrically connecting the housing and at least one of the internal electronic components to the external electronic component, the connecting device being an insulation displacement terminal , which is arranged on the housing or the external electronic component, or at least two insulation displacement terminals, one of which is arranged on the housing and a second on the external electronic component, and one Connecting cable, which can be clamped into one insulation displacement terminal or the at least two insulation displacement terminals with the production of an electrical and mechanical connection.

In vorteilhafter Weise kann durch diese Verbindungstechnik der Akustiker die Länge der Verbindung individuell für jeden Patienten während der Anpassung z. B. mit einer Schere einfach einstellen. Die verwendeten Verbindungsleitungen beziehungsweise -kabel können als Kunststoffvollprofil oder Kunststoffschlauch mit integrierten elektrischen Leitern ausgeführt sein, die selbst keine speziellen Verbindungselemente besitzen. Damit lassen sich die Verbindungskabel als Meterware herstellen und können ohne weiteres individuell in der Länge angepasst werden. Die Verbindung in Schneid-Klemm-Technik ist darüber hinaus lösbar, so dass sich ein Kürzen des Verbindungskabels durch Abschneiden und ein Verlängern durch Einsetzen eines längeren Verbindungskabels realisieren lässt. Durch die Schneid-Klemm-Technik ist eine stabile, leicht anpassbare, auch mehradrige Verbindung zwischen Hörgerät und externer Elektronikkomponente, insbesondere Hörer, gewährleistet.Advantageously, this connection technique allows the acoustician to determine the length of the connection individually for each patient during the adaptation, e.g. B. simply adjust with scissors. The connecting lines or cables used can be designed as a solid plastic profile or plastic hose with integrated electrical conductors, which themselves have no special connecting elements. This means that the connecting cables can be manufactured by the meter and can easily be individually adjusted in length. The connection using insulation displacement technology can also be detached, so that the connecting cable can be shortened by cutting and extended by inserting a longer connecting cable. The insulation displacement technology ensures a stable, easily adaptable, even multi-core connection between the hearing aid and the external electronic component, in particular the handset.

In einer vorteilhaften Ausgestaltung umfasst die Elektronikkomponente eine Hörereinrichtung, einen Funkempfänger, ein externes Mikrofon oder ein Mikrofonarray. Die Elektronikkomponente kann aber auch ein zweites Hörgerät sein, zu dem eine Crossverbindung hergestellt ist.In an advantageous embodiment, the electronic component comprises a receiver device, a radio receiver, an external microphone or a microphone array. However, the electronic component can also be a second hearing device to which a cross connection is established.

Das Verbindungskabel kann an einer Seite mit einer Schneidklemme und an der anderen Seite fest oder über einen Stecker mit der jeweiligen Komponente verbunden sein. Damit sind beliebige Kombinationen der Verbindungstechnik zwischen dem Hörgerät, dem Verbindungskabel und der externen Elektronikkomponente ausführbar.The connecting cable can be fixed on one side to an insulation displacement terminal and on the other side or connected to the respective component via a plug. Any combination of the connection technology between the hearing aid, the connection cable and the external electronic component can thus be carried out.

Das Verbindungskabel beziehungsweise dessen Kunststoff als Trägermaterial sollte günstigerweise transparent sein. Damit kann das Hörgerät wenig auffällig am Ohr angebracht werden.The connecting cable or its plastic as the carrier material should advantageously be transparent. This means that the hearing aid can be attached to the ear in an unobtrusive manner.

Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.Further advantageous configurations result from the subclaims.

Die nachfolgend beschriebenen Ausführungsbeispiele stellen bevorzugte Ausführungsformen der Erfindung dar.The exemplary embodiments described below represent preferred embodiments of the invention.

In FIG 1 ist schematisch der Querschnitt durch ein erfindungsgemäßes, zweiadriges Verbindungskabel zwischen einem Hörgerät und einer externen Elektronikkomponente dargestellt. Das Verbindungskabel 1 besteht aus einem im Wesentlichen transparenten Trägermaterial 2. In das Trägermaterial 2 sind zwei elektrische Leiter 3 eingegossen. In Längsrichtung des Verbindungskabels 1 ist eine Nut 4 vorgesehen, die als mechanischer Schlüssel zur Verpolsicherung dient. Das Verbindungskabel besitzt ferner eine Außenhülle 5 aus einem biokompatiblen Material, das für den Hörgeräteträger hautverträglich ist.1 schematically shows the cross section through an inventive two-core connecting cable between a hearing aid and an external electronic component. The connecting cable 1 consists of an essentially transparent carrier material 2. Two electrical conductors 3 are cast into the carrier material 2. In the longitudinal direction of the connecting cable 1, a groove 4 is provided, which serves as a mechanical key for reverse polarity protection. The connecting cable also has an outer sheath 5 made of a biocompatible Material that is skin-friendly for the hearing aid wearer.

In Abhängigkeit von der Materialwahl des Trägers 2 und der Außenhülle 5 kann das Verbindungskabel 1 plastisch verformbar und formstabil oder vollflexibel sein. Die elektrischen Leiter 3 können aus Metall oder einem leitenden Kunststoff bestehen.Depending on the choice of material for the carrier 2 and the outer sheath 5, the connecting cable 1 can be plastically deformable and dimensionally stable or fully flexible. The electrical conductors 3 can consist of metal or a conductive plastic.

Da das Verbindungskabel über die gesamte Länge den gleichen Querschnitt aufweist - es liegt beispielsweise als Meterware vor -, können durch Abschneiden beliebig lange Stücke hergestellt und die Verbindung zwischen Hörgerät und externer Elektronikkomponente individuell eingestellt werden. Darüber hinaus kann das Verbindungskabel 1 nicht dargestellte, elektrische Bauelemente wie beispielsweise Schalter, Taster, ICs etc. enthalten.Since the connecting cable has the same cross-section over the entire length - it is available by the meter, for example - pieces of any length can be cut and the connection between the hearing aid and the external electronic component can be set individually. In addition, the connecting cable 1 may contain electrical components, not shown, such as switches, buttons, ICs, etc.

Eine abgewandelte Ausführungsform eines erfindungsgemäßen Verbindungskabels ist in FIG 2 dargestellt. In diesem Fall besitzt das Verbindungskabel 1 einen länglichen Querschnitt, wobei die beiden Leiter in der Nähe der Enden der Querschnittslängsform angeordnet sind. Als mechanischer Schlüssel zur Verpolsicherung ist hier eine nach außen ragende Rille beziehungsweise Nase 5 gewählt. Eine biokompatible Außenhülle ist hier nicht eingezeichnet, sie kann aber dennoch vorhanden sein. Sie ist jedoch nicht notwendig, wenn das Trägermaterial bereits biokompatibel ist.A modified embodiment of a connecting cable according to the invention is shown in FIG. In this case, the connecting cable 1 has an elongated cross section, the two conductors being arranged near the ends of the cross-sectional longitudinal shape. An outwardly protruding groove or nose 5 is selected here as the mechanical key for reverse polarity protection. A biocompatible outer shell is not shown here, but it can still be present. However, it is not necessary if the carrier material is already biocompatible.

In FIG 3 ist eine mehradrige Variante eines erfindungsgemäßen Verbindungskabels 1 dargestellt. Der Aufbau entspricht grundsätzlich dem des Verbindungskabels von FIG 1. In dem Kabel sind jedoch insgesamt sechs Leiter 3 gegeneinander durch das Trägermaterial 2 isoliert angeordnet. Fünf der Leiter 3 sind am Außenumfang des Trägers 2 angeordnet und ringsegmentförmig ausgebildet. Selbstverständlich können die fünf Leiter 3 auch kreisförmigen Querschnitt besitzen. Ein sechster Leiter 3 mit kreisförmigem Querschnitt ist im Zentrum des Verbindungskabels 1 angeordnet. Derartige mehradrige Kabel eignen sich insbesondere für Crossverbindungen von Hörgeräten.3 shows a multi-core variant of a connecting cable 1 according to the invention. The structure basically corresponds to that of the connecting cable from FIG. 1. However, a total of six conductors 3 are insulated from one another by the carrier material 2 in the cable. Five of the conductors 3 are arranged on the outer circumference of the carrier 2 and have the shape of a ring segment. Of course, the five conductors 3 can also have a circular cross section. A sixth conductor 3 with circular cross section is arranged in the center of the connecting cable 1. Such multi-core cables are particularly suitable for cross connections of hearing aids.

In FIG 4 ist eine erfindungsgemäße Schneidklemme im Querschnitt dargestellt. Die Schneidklemme besitzt einen zylinderförmigen Grundkörper 10, an dessen Außenumfang mehrere Schneiden 11 angebracht sind. Die Schneiden ragen bezogen auf die Längsachse des Zylinders 10 schräg nach außen. Sie bestehen aus einem flexiblen Arm 12, der am proximalen Ende fest am Außenumfang des Zylinderkörpers 10 angebracht ist, und aus einer Messerklinge 13, die am distalen Ende des Arms 12 zur Längsachse des Zylinderkörpers 10 nach innen ragend angeordnet ist. Alternativ können die Arme 12 auch starr ausgeführt und schwenkbar an dem Zylinderkörper 10 befestigt sein.4 shows an insulation displacement terminal according to the invention in cross section. The insulation displacement terminal has a cylindrical base body 10, on the outer circumference of which a plurality of cutting edges 11 are attached. The cutting edges protrude obliquely outwards with respect to the longitudinal axis of the cylinder 10. They consist of a flexible arm 12, which is fixedly attached to the outer periphery of the cylinder body 10 at the proximal end, and of a knife blade 13, which is arranged on the distal end of the arm 12 and projects inwards to the longitudinal axis of the cylinder body 10. Alternatively, the arms 12 can also be rigid and pivotally attached to the cylinder body 10.

Im Zentrum des Zylinderkörpers 10 ist ein Dorn vorgesehen, der zur Kontaktierung einer zentral in dem Verbindungskabel 1 angeordneten Ader dient. Sowohl der Dorn 14 als auch die Arme 12 der Schneiden 11 sind durch elektrische Anschlüsse 15 kontaktiert. Um den Zylinderkörper 10 ist ein Klemmring 16 angeordnet, der längs der Rotationssymmetrie des Zylinderkörpers 10 verschiebbar ist und der zum Eindrücken und Festklemmen der Schneiden 11 in das Verbindungskabel 1 dient.In the center of the cylinder body 10, a mandrel is provided, which serves to contact a core arranged centrally in the connecting cable 1. Both the mandrel 14 and the arms 12 of the cutting edges 11 are contacted by electrical connections 15. Arranged around the cylinder body 10 is a clamping ring 16 which can be displaced along the rotational symmetry of the cylinder body 10 and which is used for pressing and clamping the cutting edges 11 into the connecting cable 1.

Eine Draufsicht auf die erfindungsgemäße Schneidklemme ist in FIG 5 wiedergegeben. Bei diesem Ausführungsbeispiel sind sechs Schneiden 11, jeweils bestehend aus einem Arm 12 und einer Messerklinge 13, gleichmäßig am Außenumfang des Zylinderkörpers 10 schräg nach außen ragend angeordnet. Der Klemmring 16 ist in FIG 5 nicht dargestellt. In der Draufsicht ist jedoch eine Nase 17 zu erkennen, die als Verpolschutz dient und in die Nut 4 eines Verbindungskabels 1 eingreift. Die Nase 17 ragt aus der Oberfläche des Zylinderkörpers 10 in Richtung der Rotationssymmetrieachse des Zylinderkörpers 10.A top view of the insulation displacement clamp according to the invention is shown in FIG. 5. In this exemplary embodiment, six cutting edges 11, each consisting of an arm 12 and a knife blade 13, are arranged so as to protrude evenly on the outer circumference of the cylinder body 10. The clamping ring 16 is not shown in FIG 5. In the top view, however, a nose 17 can be seen, which serves as reverse polarity protection and engages in the groove 4 of a connecting cable 1. The nose 17 protrudes from the surface of the cylinder body 10 in the direction of the rotational symmetry axis of the cylinder body 10.

Bei der Herstellung der Schneid-Klemm-Verbindung wird die Verbindungsleitung 1 mit ihrer Stirnseite auf die Stirnseite des Zylinderkörpers 10 gedrückt. Hierdurch wird gegebenenfalls der Kontakt zwischen dem Dorn 14 und einem zentral in dem Verbindungskabel 1 angeordneten Leiter 3 hergestellt. Anschließend wird der Klemmring 16 in FIG 4 nach oben (Pfeilrichtung A) geschoben. Hierdurch werden die Schneiden 11 nach innen gedrückt, wodurch die Messerklingen 13 durch die Außenhülle 5 des Verbindungskabels 1 in die entsprechenden Leiter 3 eindringen und elektrische Verbindung herstellen. Die Schneiden 11 vollziehen hierbei die mit den Pfeilen B angedeutete nach innen gerichtete Bewegung. Der Klemmring 16 wird mit seiner Oberkante geringfügig über das distale Ende der Arme 12 der Schneiden 11 geschoben und rastet in dieser Stellung ein, wobei die Schneiden 11 in das Verbindungskabel 1 gedrückt sind. In diesem Zustand sorgen die Schneiden 11 nicht nur für einen elektrischen Kontakt zu den Leitern 3 sondern fixieren das Verbindungskabel 1 auch in seiner Längsrichtung auf dem Zylinderkörper 10, der seinerseits an dem Hörgerät oder der externen Elektronikkomponente befestigt ist.When producing the insulation displacement connection, the end face of the connecting line 1 is pressed onto the end face of the cylinder body 10. As a result, the contact between the mandrel 14 and a conductor 3 arranged centrally in the connecting cable 1 is established. Subsequently, the clamping ring 16 in FIG. 4 is pushed upward (arrow direction A). As a result, the cutting edges 11 are pressed inwards, as a result of which the knife blades 13 penetrate into the corresponding conductors 3 through the outer casing 5 of the connecting cable 1 and establish an electrical connection. The cutting edges 11 carry out the inward movement indicated by the arrows B. The clamping ring 16 is pushed with its upper edge slightly over the distal end of the arms 12 of the cutting edges 11 and engages in this position, the cutting edges 11 being pressed into the connecting cable 1. In this state, the cutters 11 not only ensure electrical contact with the conductors 3 but also fix the connecting cable 1 in its longitudinal direction on the cylinder body 10, which in turn is attached to the hearing aid or the external electronic component.

Die dargestellte Schneid-Klemm-Verbindung kann in Kombination mit anderen Verbindungstechniken beliebig eingesetzt werden. So können beispielsweise folgende Verbindungskombinationen praktikabel sein:

  • a) Schneid-Klemm-Verbindung sowohl am Hörgerät als auch an der externen Elektronikkomponente
  • b) Steckverbinder am Hörgerät und Schneid-Klemm-Verbindung an der externen Elektronikkomponente
  • c) Steckverbinder an der externen Elektronikkomponente und Schneid-Klemm-Verbindung am Hörgerät
  • d) feste Verbindung am Hörgerät und Schneid-Klemm-Verbindung an der externen Elektronikkomponente und
  • e) feste Verbindung an der externen Elektronikkomponente und Schneid-Klemm-Verbindung am Hörgerät.
