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
Der Wunsch nach kostengünstigen und miniaturisierten Hörgeräten führte zu kapselförmigen Geräten, die etwas mehr als einen Zentimeter lang sind und in der Helix bzw. der Cymba Conchae getragen werden können. Das Ausgangssignal des Hörgeräts wird über einen Schallschlauch oder im Falle eines RIC-Hörgeräts mit Hilfe eines elektrischen Leiters durch die Concha zum Gehörgang geführt.The desire for cost-effective and miniaturized hearing aids led to capsule-shaped devices that are a little over one centimeter long and in the helix or the Cymba Conchae can be worn. The output of the hearing aid is routed via a sound tube or in the case of a RIC hearing aid by means of an electrical conductor through the Concha to the ear canal.
Für das in der Helix tragbare Hörgerät werden soweit wie möglich Standardkomponenten eingesetzt, um den Preis des Hörgeräts möglichst gering zu halten. Dies schließt ein, dass das Gehäuse des Hörgeräts als einfaches Kunststoffspritzgussteil hergestellt wird. Ein derartiges Gehäuse besitzt eine Standardform und ist in der Regel unnachgiebig. Somit lässt der Tragekomfort vielfach zu wünschen übrig. Insbesondere kommt es zu Druckstellen an der Anti-Helix oder der Crus helicis.As far as possible standard components are used for the hearing aid that can be worn in the helix in order to keep the price of the hearing aid as low as possible. This includes that the housing of the hearing aid is made as a simple plastic injection molded part. Such a housing has a standard shape and is usually unyielding. Thus, the wearing comfort leaves much to be desired. In particular, there are pressure points on the anti-helix or the crus helicis.
Die Aufgabe der vorliegenden Erfindung besteht somit darin, den Tragekomfort einer in der Ohrmuschel zu tragenden Hörvorrichtung, die ein Standardgehäuse besitzt, zu verbessern.The object of the present invention is therefore to improve the wearing comfort of a hearing aid to be worn in the auricle, which has a standard housing.
Darüber hinaus soll ein Verfahren zum Herstellen einer derartigen Hörvorrichtung angegeben werden.In addition, a method for producing such a hearing device is to be specified.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine Hörvorrichtung zum Tragen in einer Ohrmuschel mit einem Gehäuse, in dem eine Schallsignalverarbeitungseinrichtung untergebracht ist, und einem Leiter zum Leiten eines akustischen oder elektrischen Signals von dem Gehäuse in einen Gehörgang eines Nutzers, wobei ein Formteil, das individuell an einen Teil der Ohrmuschel des Nutzers angepasst und zweiteilig mit dem Gehäuse gebildet ist, an dem Gehäuse befestigt ist.According to the invention, this object is achieved by a hearing device for carrying in an auricle with a housing in which a sound signal processing device is housed, and a conductor for conducting an acoustic or electrical signal from the housing into an auditory canal of a user, wherein a molded part, the individually a part of the user's ear is adapted and formed in two parts with the housing is attached to the housing.
In vorteilhafter Weise ist es so möglich, bei einer Hörvorrichtung mit Standardgehäuse den Tragekomfort eines individuell angepassten Gehäuses zu erreichen.Advantageously, it is possible to achieve in a hearing device with standard housing the comfort of an individually adapted housing.
Das Formteil kann an das Gehäuse angeklebt sein. Auf diese Weise ist es stabil ohne aufwändige Verbindungskomponenten an dem Gehäuse angebracht.The molded part can be glued to the housing. In this way, it is stable without expensive connecting components attached to the housing.

Die nachfolgend näher geschilderten Ausführungsbeispiele stellen bevorzugte Ausführungsformen der vorliegenden Erfindung dar. Zunächst sei jedoch anhand von
Die feste Geometrie des Gehäuses 11 des Hörgeräts 10 hat einerseits den Vorteil, dass es als Massenprodukt sehr kostengünstig für zahlreiche Nutzer in unveränderter Form hergestellt werden kann. Da jedoch andererseits die Ohrmuscheln der Hörgeräteträger stets individuell geformt sind, sitzt das Hörgerät entweder sehr locker oder es wird in gewissen Bereichen der Cymba unangenehmer Druck ausgeübt. Dieser Druck wird umso unangenehmer empfunden, je punktueller er ausfällt. Falls jedoch nur ein sehr geringer oder kein Druck auf den Cymbabereich ausgeübt wird, d. h. die Cymba Conchae ist etwas größer als eine Durchschnitts-Cymba Conchae, so besteht fortlaufend die Gefahr, dass das Hörgerät aus der Ohrmuschel fällt.The fixed geometry of the
In Anbetracht der obigen Problematik ist nun erfindungsgemäß vorgesehen, dass gemäß
Anhand der ermittelten individuellen Form des Teils der Ohrmuschel wird nun das Formteil 14 getrennt von dem Gehäuse 11 hergestellt. Die Kontur des Formteils 14 entspricht dann exakt der negativen Kontur des Teils der Ohrmuschel 17, in den das Hörgerät einzusetzen ist (vgl.
Durch das individuelle Anpassen des Formteils 14 an die vorliegende Ohrmuschel kommt es bei gleicher Haltekraft zu einer geringeren Deformation des Teils der Ohrmuschel 17, in das den Hörgerät 10 eingesetzt ist. Dies steigert den Tragekomfort, denn durch das Formteil 14 wird nun der Druck gleichmäßig auf die angrenzenden Teile der Ohrmuschel übertragen. Außerdem reduziert sich durch das Formteil 14 die Gefahr des Herausfallens des Hörgeräts 10, denn durch das Formteil 14 ist ein gewisser Formschluss gegeben.Due to the individual adaptation of the
Das Formteil 14 gleicht Lücken und Druckstellen aus. Um diese Funktion noch besser erfüllen zu können, kann das Material des Formteils 14 weich, insbesondere gummielastisch oder schaumstoffartig sein.The
Die Fertigung des Formteils 14 kann mit Hilfe einer üblichen SLA-Technik im Rahmen eines RSM-Verfahrens (Rapid Shell Manufacturing) erfolgen. Dies gewährleistet einen hohen Automatisierungsgrad.The production of the
Da das Hörgerät nicht in der Concha oder im Gehörgang platziert ist, kann wie bei HdO-Hörgeräten leicht eine offene Versorgung realisiert werden. Insbesondere ist, wie oben bereits angesprochen, eine RIC-Lösung möglich, was nicht nur zu einem hohen Tragekomfort führt, sondern auch hinsichtlich ästhetischen Aspekten vorteilhaft ist.Since the hearing aid is not placed in the concha or in the auditory canal, as in BTE hearing aids can be easily realized an open supply. In particular, as already mentioned above, a RIC solution is possible, which not only leads to a high wearing comfort, but is also advantageous in terms of aesthetic aspects.
In der Praxis wird sich ein Nutzer ein als Massenprodukt erhältliches Hörgerät beschaffen. Ein Akustiker wird einen Ohrabdruck des Teils des Ohr abnehmen, in dem das Hörgerät getragen wird. Alternativ scannt der Akustiker diesen Teil des Ohrs ein. Anschließend wird das entsprechende individuelle Formteil gefertigt. Schließlich wird das Formteil an das Gehäuse 11 des Hörgeräts 10 aufgeklebt, gesteckt, geklippst oder anderweitig befestigt. Damit ist das ursprünglich als Massenprodukt erworbene Hörgerät für komfortables Tragen individualisiert.In practice, a user will obtain a mass-produced hearing aid. An acoustician will remove an ear impression of the part of the ear in which the hearing aid is worn. Alternatively, the acoustician scans this part of the ear. Subsequently, the corresponding individual molded part is manufactured. Finally, the molding is adhered to the
