Description

Die Erfindung betrifft ein Hörgerät gemäß dem Oberbegriff des Anspruchs 1. Ein derartiges Hörgerät ist beispielsweise aus der DE 198 25 998 A1 bekannt.The invention relates to a hearing aid according to the preamble of claim 1. Such a hearing aid is for example from the DE 198 25 998 A1 known.

In Hörgeräten entstehen akustische Rückkopplungen (Feedback), welche durch verschiedene Konstruktionsmerkmale bedingt sind. Zwei Hauptmerkmale, welche Feedback beeinflussen, sind Gewicht und Länge des Hörgeräts. Daher neigen insbesondere leistungsstarke Hörgeräte (sog. Super Power Geräte) mit einer hohen Verstärkung und schweren Batterien dazu, Feedback im akustischen Bereich zwischen 2 und 6 kHz zu erzeugen. In fast allen Fällen kann daher im Richtmikrofonmodus keine ausreichende Verstärkung erreicht werden. Solche Hörgeräte sind üblicherweise als Hinter-dem-Ohr Hörgerät (HdO) ausgeführt und weisen ein Gehäuse auf, welches hinter dem Ohr mittels einer Aufhängung (Hook) getragen wird. Das Gehäuse umschließt den Lautsprecher (Hörer) und beherbergt Batterien zur Stromversorgung.Hearing aids generate acoustic feedbacks (feedback), which are caused by various design features. Two key features that affect feedback are the weight and length of the hearing aid. Therefore, especially high performance hearing aids (so-called super power devices) with a high gain and heavy batteries tend to generate feedback in the acoustic range between 2 and 6 kHz. In almost all cases, therefore, sufficient amplification can not be achieved in directional microphone mode. Such hearing aids are usually designed as behind-the-ear hearing aids (BTE) and have a housing which is worn behind the ear by means of a hook. The housing encloses the speaker (earphone) and houses batteries for power supply.

Alle Versuche das Rückkopplungsproblem zu lösen, basieren darauf, das Mikrophon vom Gehäuse zu entkoppeln, in dem es aufgehängt ist, oder den Hörer so aufzuhängen, dass so viel Vibrationsenergie wie möglich durch die anwendungsspezifisch geformten Aufhängungen, die aus weichem Gummimaterial gebildet sind, aufgenommen werden ( US 20100208927 ). Diese Konzepte haben physikalische Grenzen und sind meist nicht genügend, um hohe Verstärkung im Richtmikrophonmodus zu erzielen. Bis jetzt gibt es nur eine bekannte Vorrichtung (Sumo von Oticon) mit einem äußerststabilen omnidirektionalen Modus, die aber kein Richtmikrophonmodus anbietet. Es gibt auch ein spezielles Hook Design ( US 20080085024 A1 ), das die Vibrationen verringert.All attempts to solve the feedback problem are based on decoupling the microphone from the housing in which it is suspended or suspending the handset so as to absorb as much vibrational energy as possible through the custom shaped suspensions formed of soft rubber material ( US 20100208927 ). These concepts have physical limitations and are usually insufficient to achieve high gain in the directional microphone mode. So far, there is only one known device (Sumo of Oticon) with a highly stable omnidirectional mode, but does not offer a directional microphone mode. There is also a special hook design ( US 20080085024 A1 ), which reduces the vibrations.

Ein Hörgerät mit Dämpfungselement zwischen einem Hauptgehäuse und einem Schlauch zum Hauptgehäuse ist in CH 699444 B1 gezeigt. Diese Lösung ist ausreichend für kleinere und weniger leistungsfähige Vorrichtungen, aber stärkere Geräte benötigen andere Lösungen.A hearing aid with a damping element between a main housing and a hose to the main housing is in CH 699444 B1 shown. This solution is sufficient for smaller and less powerful devices, but more powerful devices require different solutions.

Aufgabe der Erfindung ist es, ein Hörgerät bereitzustellen, welches verringerte Rückkopplung aufweist. Diese Aufgabe wird durch das Hörgerät gemäß Anspruch 1 gelöst.The object of the invention is to provide a hearing aid which has reduced feedback. This object is achieved by the hearing aid according to claim 1.

Die Erfindung betrifft ein Hörgerät nach Anspruch 1, aufweisend ein Gehäuse, in welchem ein Hörer und eine Batterie angeordnet sind, wobei das Gehäuse ein erstes Gehäuseteil, in dem die Batterie ausschlisßlich angeordnet ist, und ein zweites Gehäuseteil aufweist, in dem der Hörer ausschließlich angeordnet ist, wobei die Gehäuseteile über eine Verbindung vibrationstechnisch entkoppelt miteinander verbunden sind, und wobei mindestens das erste Gehäuseteil aus einem elastischen Material ausgebildet ist. Die Verbindung zwischen dem ersten und zweiten Gehäuseteil ist vorzugsweise eine Bajonettverbindung, kann jedoch auch eine Steckverbindung oder eine Schraubverbindung sein.The invention relates to a hearing aid according to claim 1, comprising a housing in which a receiver and a battery are arranged, wherein the housing has a first housing part in which the battery is arranged ausschlissslich, and a second housing part, in which the handset exclusively arranged is, wherein the housing parts are connected via a connection vibration-decoupled from each other, and wherein at least the first housing part is formed of an elastic material. The connection between the first and second housing part is preferably a bayonet connection, but may also be a plug connection or a screw connection.

Ein z.B. ringförmiges oder scheibenförmiges Dämpfungselement ist vorzugsweise zwischen dem ersten und dem zweiten Gehäuseteil angeordnet.An e.g. annular or disc-shaped damping element is preferably arranged between the first and the second housing part.

Bevorzugt kann das Hörgerät ein Hinter-dem-Ohr Hörgerät mit einem Hook sein. Vorzugsweise bildet der Hook das zweite Gehäuseteil, welches über die Verbindung mit dem ersten Gehäuseteil verbunden ist, wobei bei der Verbindung ein Dämpfungselement angeordnet ist.Preferably, the hearing aid may be a behind-the-ear hearing aid with a hook. Preferably, the hook forms the second housing part, which is connected via the connection with the first housing part, wherein a damping element is arranged in the connection.

Es ist bevorzugt, dass der zweite Gehäuseteil aus einem nicht-elastischen Material ausgebildet ist. Es ist ferner bevorzugt, dass das nicht-elastische Material ein Duroplastkunststoff, insbesondere ABS ist. Das elastische Material ist vorzugsweise ein Elastomerkunststoff, z.B. Silikongummi, ein Thermoplast-Elastomer (TPE) oder ein Fluorelastomer wie Viton®.It is preferred that the second housing part is formed of a non-elastic material. It is further preferred that the non-elastic material is a thermoset plastic, in particular ABS. The elastic material is preferably an elastomeric plastic, eg silicone rubber, a thermoplastic elastomer (TPE) or a fluoroelastomer such as Viton®.

Hohes Gewicht sowie die Länge des Gehäuses sind die Hauptfaktoren für starke Rückkopplung eines Hörgeräts. Dies gilt insbesondere für schwere, leistungsstarke Geräte. Besonders zwei Komponenten tragen zu einem hohen Gewicht bei schweren, leistungsstarken Geräten bei: Die Batterie und der Hörer. Ihr Gewicht kann nicht reduziert werden, ohne Leistungseinbußen hinzunehmen. Es ist jedoch möglich und erfindungsgemäß vorgesehen, diese beiden Komponenten in separaten, entkoppelten Gehäuseteilen unterzubringen. Dadurch erhält man ein Hörgerät mit zwei Teilen, die unabhängig voneinander vibrieren, und die Rückkopplungsfrequenzen werden in einen höheren Frequenzbereich verschoben (≥ 6kHz). Das ist sehr effektiv, da sowohl Länge als auch Gewicht durch die Trennung vibrationstechnisch reduziert werden.High weight as well as the length of the housing are the main factors for strong feedback of a hearing aid. This is especially true for heavy, powerful devices. Especially two components contribute to a high weight in heavy, powerful devices: the battery and the handset. Your weight can not be reduced without sacrificing performance. However, it is possible and inventively provided to accommodate these two components in separate, decoupled housing parts. This gives a hearing aid with two parts that vibrate independently of each other and the feedback frequencies are shifted to a higher frequency range (≥ 6kHz). This is very effective, as both length and weight are reduced by vibration vibration.

Die Entkopplung kann durch ein Dämpfungselement erreicht werden, dass zwischen dem ersten und zweiten Gehäuseteil angeordnet ist, z.B. ein Ring oder eine Scheibe aus dämpfendem Material, z.B. ein Elastomermaterial.The decoupling can be achieved by a damping element which is arranged between the first and second housing part, e.g. a ring or disc of damping material, e.g. an elastomeric material.

Erfindungsgemäß ist bevorzugt der Gehäuseteil, welcher die Batterie enthält, aus einem dämpfenden Material, z.B. einem Elastomermaterial, gebildet. Der andere Gehäuseteil nimmt den Hörer und vorzugsweise das Mikrophon auf, und ist geeigneterweise aus einem starren, nicht-elastischen Material, z.B. ein Duroplastmaterial oder ein starres Thermoplastmaterial, gebildet.According to the invention, the housing part which contains the battery is preferably made of a damping material, e.g. an elastomeric material formed. The other housing part receives the earphone and preferably the microphone, and is suitably made of a rigid, non-elastic material, e.g. a thermoset material or a rigid thermoplastic material.

Es wurde herausgefunden, dass bereits eine Entkopplung des Hooks vom restlichen Gehäuse durch eine Verbindung, die ein Dämpfungselement enthält, eine effektive Maßnahme zur Reduktion von Rückkopplungen ist. Eine noch effektivere Dämpfung ist gegeben, wenn das Gehäuse in zwei Gehäuseteile aufgeteilt ist, wobei in einem Gehäuseteil die Batterie und im anderen Gehäuseteil der Hörer untergebracht ist, und wobei ein Gehäuseteil aus einem elastischen oder weichen dämpfenden Material gebildet ist oder ein Dämpfungselement zwischen den beiden Gehäuseteilen angeordnet ist. Die Ausführungsform mit einem Gehäuseteil aus einem elastischen oder weichen dämpfenden Material hat sich in Versuchen als die effektivste Maßnahme zur Unterdrückung von Rückkopplungen erwiesen.It has been found that even decoupling the hook from the remainder of the housing through a connection that includes a damping element is an effective measure for reducing feedback. An even more effective damping is given when the housing is divided into two housing parts, wherein in one housing part, the battery and in the other Housing part of the listener is housed, and wherein a housing part made of an elastic or soft damping material is formed or a damping element between the two housing parts is arranged. The embodiment with a housing part made of an elastic or soft damping material has proved in experiments as the most effective measure for suppressing feedback.

Diese Ausführungsform weist einen ersten Gehäuseteil aus elastischem und dämpfendem Material auf, der die Batterie des Hörgeräts umschließt. Die gestrichelte Linie zeigt das Rückkopplungsverhalten eines Hörgeräts mit einem einteiligen, starren Gehäuse gemäß dem Stand der Technik. FIG. 7 shows a diagram illustrating the feedback behavior of the hearing aid according to the invention according to the embodiment of FIG FIG. 2 represents. This embodiment has a first housing part made of elastic and damping material, which encloses the battery of the hearing aid. The dashed line shows the feedback behavior of a hearing aid with a one-piece, rigid housing according to the prior art.

Bei ca. 4 kHz und 6-7 kHz sind hohe Maxima der Übertragungsfunktion zu sehen, die auf Rückkopplungen in diesen Frequenzbereichen hinweisen (ideal wäre ein linearer Frequenzverlauf ohne Minima oder Maxima). Die durchgezogene dicke Linie zeigt das Rückkopplungsverhalten eines erfindungsgemäßen Hörgeräts mit einem ersten Gehäuseteil aus elastischem und dämpfendem Material. Die durchgezogene dünne Linie zeigt das Rückkopplungsverhalten eines erfindungsgemäßen Hörgeräts mit einem ersten Gehäuseteil aus elastischem und dämpfendem Material und einem Dämpfungselement zwischen Hook und dem restlichen Gehäuse, was einer Kombination der Merkmale der Ausführungsformen nach Figur 2 und Figur 4 entspricht. Bei beiden erfindungsgemäßen Hörgeräten ist zu erkennen, dass die scharf abgegrenzten Maxima bei ca. 4 kHz und 6-7 kHz nicht mehr vorhanden sind und der Frequenzverlauf insgesamt dem angestrebten idealen Frequenzverlauf viel näher kommt.At approx. 4 kHz and 6-7 kHz high maxima of the transfer function are to be seen, which indicate feedbacks in these frequency ranges (ideal would be a linear frequency curve without minima or maxima). The solid thick line shows the feedback behavior of a hearing aid according to the invention with a first housing part made of elastic and damping material. The solid thin line shows the feedback behavior of a hearing aid according to the invention with a first housing part made of elastic and damping material and a damping element between the hook and the rest of the housing, resulting in a combination of the features of the embodiments FIG. 2 and FIG. 4 equivalent. In the case of both hearing aids according to the invention, it can be seen that the sharply delimited maxima are no longer present at approximately 4 kHz and 6-7 kHz, and the frequency curve as a whole comes much closer to the desired ideal frequency response.

Figur 8 zeigt ein Diagramm, welches das Rückkopplungsverhalten des Hörgeräts gemäß der Ausführungsform nach Figur 4-6 darstellt. Diese Ausführungsform weist ein Dämpfungselement zwischen Hook und dem restlichen Gehäuse auf. Die gestrichelte Linie zeigt das Rückkopplungsverhalten eines Hörgeräts gemäß dem Stand der Technik mit einem einteiligen, starren Gehäuse. FIG. 8 shows a diagram showing the feedback behavior of the hearing aid according to the embodiment according to Figure 4-6 represents. This embodiment has a damping element between the hook and the rest of the housing. The dashed line shows the feedback behavior of a hearing aid according to the prior art with a one-piece, rigid housing.

Bei ca. 4 kHz und 6 kHz sind hohe Maxima der Übertragungsfunktion zu sehen. Die durchgezogene dünne Linie zeigt das Rückkopplungsverhalten des erfindungsgemäßen Hörgeräts mit einem Dämpfungselement zwischen Hook und dem restlichen Gehäuse, was der Ausführungsform nach Figuren 4 bis 6 entspricht. Es ist zu erkennen, dass die scharf abgegrenzten Maxima bei ca. 4 kHz und 6 kHz nicht mehr vorhanden sind und der Frequenzverlauf insgesamt dem angestrebten idealen Frequenzverlauf viel näher kommt. Auch diese Dämpfungsmaßnahme ist schon überraschend gut geeignet, Rückkopplungen effektiv zu minimieren, wenn gleich die Konstruktion mit einem Gehäuseteil aus einem elastischen oder weichen dämpfenden Material noch effektiver ist (vgl. Fig. 7, wo die Rückkopplungen bei ca. 6-7 kHz vollständig unterdrückt sind).At approx. 4 kHz and 6 kHz, high maxima of the transfer function can be seen. The solid thin line shows the feedback behavior of the hearing aid according to the invention with a damping element between the hook and the remaining housing, what the embodiment FIGS. 4 to 6 equivalent. It can be seen that the sharply delimited maxima are no longer present at approx. 4 kHz and 6 kHz, and that the overall frequency curve is much closer to the ideal frequency curve. Also, this damping measure is surprisingly well suited to minimize feedback effectively if the same construction with a housing part made of an elastic or soft damping material is more effective (see. Fig. 7 where the feedback is completely suppressed at about 6-7 kHz).
