Wie in FIG 3 dargestellt, ermöglichen die Klammern 12 und 13 des Audioschuhs 10 eine Befestigung des Audioschuhs 10 an der Stirnseite 11 des Hörgeräts.As in FIG. 3 illustrated, allow the brackets 12 and 13 of the audio shoe 10 attachment of the audio shoe 10 on the front side 11 of the hearing aid.

Die zu den Klammern 12, 13 korrespondierenden Nuten 15 und 16 sind, wie in FIG 4 dargestellt, an gegenüberliegenden Seiten der Stirnseite 11 des Hörgeräts parallel zueinander angeordnet. Außerdem weist die Stirnseite 11 des Hörgeräts eine Öffnung 17 auf, die in unmittelbarer Nähe einer Kante der Stirnseite 11 und hier senkrecht zu den Nuten 11 und 15 angeordnet ist. In diese Öffnung 17 kann die Anschlussplatte 14 des Audioschuhs 10 aufgenommen und somit die elektrische Verbindung zwischen dem Audioschuh 10 und dem Hörgerät hergestellt werden.The corresponding to the brackets 12, 13 grooves 15 and 16 are, as in FIG. 4 shown, arranged on opposite sides of the end face 11 of the hearing aid parallel to each other. In addition, the end face 11 of the hearing aid has an opening 17, which is arranged in the immediate vicinity of an edge of the end face 11 and here perpendicular to the grooves 11 and 15. In this opening 17, the connection plate 14 of the audio shoe 10 can be received and thus the electrical connection between the audio shoe 10 and the hearing aid are made.

Um die Klammern 12 und 13 des Audioschuhs 10 in die korrespondierenden Nuten 15 und 16 aufzunehmen, sind die Klammern 12 und 13 an dem Audioschuh 10 bewegbar gelagert, so dass durch beidseitiges Drücken des Audioschuhs 10 an Seitenflächen 18 und 19 die Klammern 12 und 13 geöffnet werden und eine Aufnahme des Audioschuhs 10 an der Stirnseite 11 des Hörgeräts ermöglicht wird. Dieser Vorgang ist in FIG 4 anhand von Pfeilen A, B und C dargestellt. Weil die Klammern 12 und 13 bewegbar gelagert sind und eine entsprechende Phase besitzen, kann der Audioschuh 10 an die Stirnseite 11 des Hörgeräts auch ohne die Drückbewegung angesteckt werden. Der angesteckte Audioschuh 10, wie in FIG 5 gezeigt, kann dann durch Drücken an die Seitenflächen 18 und 19 des Audioschuhs 10 von dem Hörgerät wieder entfernt werden. Zum Anschließen von externen Anschlusselementen weist der Audioschuh 10 standardmäßig drei Buchsen 20 auf.To accommodate the brackets 12 and 13 of the audio shoe 10 in the corresponding grooves 15 and 16, the brackets 12 and 13 are movably mounted on the audio shoe 10, so that by pressing both sides of the audio shoe 10 at Side surfaces 18 and 19, the brackets 12 and 13 are opened and a recording of the audio shoe 10 on the front side 11 of the hearing aid is possible. This process is in FIG. 4 shown by arrows A, B and C. Because the brackets 12 and 13 are movably mounted and have a corresponding phase, the audio shoe 10 can be plugged to the end face 11 of the hearing aid without the pushing movement. The infected audio shoe 10, as in FIG. 5 can then be removed by pressing on the side surfaces 18 and 19 of the audio shoe 10 of the hearing aid again. For connecting external connection elements, the audio shoe 10 by default has three sockets 20.

Wie in FIG 6 zu erkennen ist, besteht der Audioschuh 10 essentiell aus zwei Teilen, einem Deckel 23 und einer Steckermechanik 24, die in dem Deckel 23 gelagert und mittels eines Befestigungsbolzen 22 befestigt wird. Dabei erstreckt sich der Befestigungsbolzen 22 über den Audioschuh 10 zwischen zwei gegenüberliegenden Seiten 25 und 26 des Deckels 23.As in FIG. 6 can be seen, the audio shoe 10 consists essentially of two parts, a lid 23 and a plug mechanism 24 which is mounted in the lid 23 and fastened by means of a fastening bolt 22. In this case, the fastening bolt 22 extends over the audio shoe 10 between two opposite sides 25 and 26 of the lid 23.

Die Steckermechanik 24 des Audioschuhs 10 weist eine Grundplatte 21 auf, die ferner eine durchgängige Öffnung aufweist, durch welche sich der Befestigungsbolzen 22 im befestigten Zustand erstreckt. Dadurch, dass der Befestigungsbolzen 22 an seinen beiden Enden 22a und 22b entsprechend an den beiden Seiten 25 und 26 des Deckels 23 anliegt, wird eine stabile Befestigung des wesentlichen Teils 24 in dem Deckel 23 ermöglicht.The plug mechanism 24 of the audio shoe 10 has a base plate 21, which further has a continuous opening through which the fastening bolt 22 extends in the attached state. Characterized in that the fastening bolt 22 abuts at its two ends 22a and 22b corresponding to the two sides 25 and 26 of the lid 23, a stable attachment of the essential part 24 in the lid 23 is made possible.

Entsprechend der Explosionsdarstellung von FIG 7 umfasst die Steckermechanik 24 des Audioschuhs 10 drei Schraubenfedern 31, 32 und 33, die eine Spannungskraft zwischen den Klammern 12 und 13 bewirken. Mit den Schraubenfedern 31, 32 und 33, sowie dadurch, dass die Klammern 12 und 13 bewegbar gelagert sind, ist ein Eingreifen der Klammern 12 und 13 in die korrespondierenden Nuten 15 und 16 des Hörgeräts und auf Grund der so erzielten Vorspannung eine stabile Haltung des Audioschuhs 10 an dem Hörgerät ermöglicht. Darüber hinaus sind zwei weitere Befestigungsbolzen 29 und 30 vorgesehen, die die Aufgabe haben, die Klammern 12 und 13 an der Grundplatte 21 schwenkbar zu lagern. Hierzu weist die Grundplatte 21 zwei weitere durchgängige Öffnungen auf, die sich entlang der Grundplatte 21 erstrecken.According to the exploded view of FIG. 7 For example, the plug mechanism 24 of the audio shoe 10 includes three coil springs 31, 32, and 33 that provide a clamping force between the clips 12 and 13. With the coil springs 31, 32 and 33, and in that the brackets 12 and 13 are movably mounted, an engagement of the brackets 12 and 13 in the corresponding grooves 15 and 16 of the hearing aid and due to the bias thus achieved a stable posture of Audio shoe 10 allows the hearing aid. In addition, two further fastening bolts 29 and 30 are provided, which have the task of pivotally supporting the clamps 12 and 13 on the base plate 21. For this purpose, the base plate 21 has two further continuous openings which extend along the base plate 21.

Die Grundplatte 21 weist außerdem zwei Ausschnitte 34 und 35 auf. In diese beiden Ausschnitte 34 und 35 werden die Klammern 12 und 13 im Wesentlichen senkrecht zu der Grundplatte 21 aufgenommen. Die Klammern 12 und 13 weisen jeweils eine entsprechende Aufnahme für einen Befestigungsbolzen 29, 30 auf.The base plate 21 also has two cutouts 34 and 35. In these two cutouts 34 and 35, the brackets 12 and 13 are received substantially perpendicular to the base plate 21. The brackets 12 and 13 each have a corresponding receptacle for a fastening bolt 29, 30.

Die Steckermechanik 24 des Audioschuhs 10 umfasst ferner zwei Führungselemente 27 und 28, die ausgelegt sind, die Schraubenfedern 31, 32 und 33 in Bezug auf die Klammern 12 und 13 zu führen bzw. zu stabilisieren.The plug mechanism 24 of the audio shoe 10 further comprises two guide elements 27 and 28 which are designed to guide or stabilize the coil springs 31, 32 and 33 with respect to the clamps 12 and 13.

Außerdem ist die Grundplatte 21 mit einer länglichen Öffnung 36 versehen, deren Längsrichtung senkrecht zu den Befestigungsbolzen 22, 29, 30 verläuft und durch welche die Anschlussplatte 14 aus dem Audioschuh 10 hinausragt. Wie bereits erwähnt, weist der Audioschuh 10 drei Buchsen 20 auf, die den Anschluss von externen Steckern ermöglichen. Um die elektrische Verbindung zwischen den externen Steckern und dem Hörgerät zu ermöglichen, weist die Anschlussplatte 14 drei entsprechende Leiterbahnen auf. Hierzu haben die Schraubenfedern 31, 32 und 33 weiterhin die Aufgabe, die externen Stecker mit jeweils einer entsprechenden Leiterbahn der Anschlussplatte zu verbinden, indem ein Steckerstift zwischen zwei Windungen einer Schraubenfeder geklemmt wird. Diese doppelte Funktion der Schraubenfedern 31, 32 und 33 erlaubt es, auf zusätzliche Bauelemente zur Verbindung der Buchsen 20 mit der Anschlussplatte 14 zu verzichten. Dadurch wird auch ein platzsparender Aufbau des Audioschuhs geschaffen.In addition, the base plate 21 is provided with an elongated opening 36 whose longitudinal direction is perpendicular to the fastening bolts 22, 29, 30 and through which the connection plate 14 protrudes from the audio shoe 10. As already mentioned, the audio shoe 10 has three sockets 20 which allow the connection of external plugs. In order to enable the electrical connection between the external plugs and the hearing aid, the connection plate 14 has three corresponding conductor tracks. For this purpose, the coil springs 31, 32 and 33 continue to have the task to connect the external connector, each with a corresponding trace of the terminal plate by a pin between two turns of a coil spring is clamped. This dual function of the coil springs 31, 32 and 33 makes it possible to dispense with additional components for connecting the sockets 20 to the connection plate 14. This also creates a space-saving design of the audio shoe.
