- a cross section through an inventively protected hearing aid opening, and
- FIG. 2
- a plan view of the opening of FIG. 1
Das nachfolgend geschilderte Ausführungsbeispiel stellt eine bevorzugte Ausführungsform der vorliegenden Erfindung dar.The embodiment described below provides a preferred embodiment of the present invention.
In dem Gehäuse G eines Hörgeräts ist eine Bohrung B vorgesehen. Unterhalb der Bohrung B ist ein Wandler W, z.B. ein Hörer oder Mikrofon, angeordnet. Um den Wandler W in der Bohrung B dämpfend zu fixieren befindet sich ein Dämpfungsring D zwischen der Bohrungsinnenwand und dem zylindrischen Teil des Wandlers W, der in die Bohrung B ragt. Der Öffnungsquerschnitt des Dämpfungsrings D nimmt beginnend von der Stirnseite des Wandlers W nach außen bzw. oben konisch zu.In the housing G of a hearing aid, a bore B is provided. Below the bore B is a transducer W, e.g. a listener or microphone, arranged. To the transducer W in the hole B damping to fix is a damping ring D between the bore inner wall and the cylindrical part of the Converter W, which projects into the hole B. The opening cross-section of the damping ring D starts from the front side of the transducer W to the outside or top conical to.
An der Außenseite der Bohrung ist zentrisch ein Kegel K angebracht, der mit Hilfe von Stützen S in dieser Position gehalten wird, wie dies insbesondere FIG 2 zu entnehmen ist. Der Kegel K ist mit dem Gehäuse G einteilig verbunden und stellt mit diesem ein Spritzgussteil dar. Darüber hinaus kann der Kegel K zu einem Teil in den Wandler W hineinragen.On the outside of the hole centric a cone K is attached, which held by means of supports S in this position is, as shown in particular FIG 2 can be seen. Of the Kegel K is integrally connected to the housing G and provides In addition, the one injection molded part Cone K protrude to a part in the transducer W.
Der Winkel des Kegels K ist so gestaltet, dass sich im Zusammenspiel mit dem Öffnungswinkel des Dämpfungsrings D der gesamte Öffnungsquerschnitt zum Wandler W hin verringert. Damit können Verschmutzungspartikel, die in die Öffnung geraten, leicht wieder entfernt werden. Akustisch hat der Kegel K keinen Einfluss, da der gesamte Querschnitt der Öffnung in der axialen Richtung der Öffnung etwa gleich bleibt. Vielmehr ist der Öffnungsquerschnitt an allen axialen Stellen groß genug, dass die ein- bzw. ausfallenden Schallwellen ungehindert durchtreten können.The angle of the cone K is designed so that in interaction with the opening angle of the damping ring D of the entire Opening cross-section of the transducer W toward reduced. In order to Pollution particles that get into the opening can easily removed again. Acoustically, the cone K has no Influence, since the entire cross section of the opening in the axial direction of the opening remains approximately the same. Rather, it is the opening cross-section is large enough at all axial points, that the incoming and outgoing sound waves unhindered can pass through.
Im vorliegenden Beispiel sind das Gehäuse G und der als Schutzeinrichtung dienende Kegel K, die miteinander einteilig ausgebildet sind, mit einer schmutzabweisenden Schutzschicht beschichtet. Diese Schutzschicht zeichnet sich dadurch aus, dass die Adhäsionskräfte zu Schmutzpartikeln verhältnismäßig gering sind. Daher kann sich das an vielen anderen Materialien an sich stark anhaftende Cerumen an dieser Schutzschicht kaum anlagern. Ähnliches gilt auch beispielsweise für Schweiß. Diejenigen Partikel, die sich dennoch an dem beschichteten Gehäuse bzw. der Schutzeinrichtung anlagern, können in der Regel durch Abklopfen entfernt werden. In the present example, the housing G and the as Guard cone K, which are integral with each other are formed, with a dirt-repellent protective layer coated. This protective layer is characterized by that the adhesion forces to dirt particles relatively are low. Therefore, this can affect many other materials strongly adhering cerumen to this protective layer hardly attach. The same applies, for example, to Sweat. Those particles that still stick to the coated one Housing or the protective device attach, can usually removed by tapping.
Auch der Dämpfungsring D oder andere Komponenten wie beispielsweise der Wandler W können mit der Schutzschicht versehen sein. Damit können sich auch an diesen Komponenten Schmutzpartikel weniger stark anlagern.Also, the damping ring D or other components such as the transducer W can be provided with the protective layer be. This can also affect these components Apply dirt particles less strongly.
