Aufgrund der bei Hörhilfegeräten angestrebten Miniaturisierung ist der an einem Gehäuse eines Hörhilfegerätes für die Anbringung von Bedienelementen zur Verfügung stehende Platz eng begrenzt. Daher werden bei Hörhilfegeräten auch Bedienelemente verwendet, bei denen mit einem Bedienelement mehrere Bedienfunktionen ausgeführt werden können. Üblicher Weise sind die Bedienelemente entweder direkt auf einer Leiterplatte befestigt oder am Gehäuse des betreffenden Hörhilfegerätes befestigt und mit Litzen oder Drähten elektrisch mit einer Leiterplatte verbunden.Due to the miniaturization aimed at in hearing aids, the space available on a housing of a hearing aid for attaching operating elements is narrowly limited. Therefore, in hearing aids also controls are used in which a control several functions can be performed. Usually, the controls are either attached directly to a circuit board or attached to the housing of the hearing aid in question and electrically connected to wires or wires with a circuit board.

The printed circuit board has a part of the electrical components on a boom and has a bending zone free of components. Due to the flexible circuit board, the electrical components of the known hearing aid can be accommodated very space-saving in the housing of the device.
Aus der DE 38 50 322 T2 ist ein Hörgerät mit Kontrollschalter mit zwei Arbeitsstellungen bekannt, bei dem eine Antriebswelle senkrecht zur Gehäusewand angeordnet ist und zwischen einer eingeschobenen Position nahe dem Gehäuse und einer ausgezogenen Position bewegbar ist, wobei in den verschiedenen Positionen entweder geschaltet oder der Wert eines variablen Widerstandes geändert werden kann.From DE 38 50 322 T2 a hearing aid with control switch with two working positions is known, in which a drive shaft is arranged perpendicular to the housing wall and between an inserted position near the housing and an extended position is movable, either switched in the various positions or the Value of a variable resistor can be changed.
Aufgabe der vorliegenden Erfindung ist es, bei einem Hörhilfegerät ein bewegliches Schaltelement mit einer Leiterplatte elektrisch zu verbinden.The object of the present invention is to electrically connect a movable switching element to a printed circuit board in a hearing aid.
Diese Aufgabe wird gelöst durch ein Hörhilfegerät mit einem Eingangswandler zur Aufnahme eines Eingangssignals und Wandlung in ein elektrisches Eingangssignal, einer Signalverarbeitungseinheit zur Verarbeitung des elektrischen Eingangssignals und einem Ausgangswandler zur Wandlung des verarbeiteten elektrischen Eingangssignals in ein von einem Benutzer wahrnehmbares Ausgangssignal, wobei die Signalverarbeitungseinheit mittels eines von dem Benutzer betätigbaren Bedienelements einstellbar ist, wobei das Bedienelement elektrische Anschlüsse aufweist und um eine erste Achse rotierbar sowie um eine zweite Achse schwenkbar ausgebildet ist, wobei elektrische Bauelemente der Signalverarbeitungseinheit auf einer Leiterplatte angeordnet sind und wobei zur Verbindung der elektrischen Kontakte des Bedienelements und der Leiterplatte eine flexible Leiterplatte vorhanden ist.This object is achieved by a hearing aid with an input transducer for receiving an input signal and conversion to an electrical input signal, a signal processing unit for processing the electrical input signal and an output transducer for converting the processed electrical input signal into a user-perceivable output signal, wherein the signal processing unit by means of a is adjustable by the user operable control element, wherein the control element has electrical connections and rotatable about a first axis and is pivotable about a second axis, wherein electrical components of the signal processing unit are arranged on a circuit board and wherein for connection of the electrical contacts of the control element and the PCB a flexible circuit board is present.
Bei der Erfindung ist ein Bedienelement um eine erste Achse rotierbar und um eine zweite Achse schwenkbar ausgebildet. Beispielsweise handelt es sich bei dem Bedienelement um einen VC-Steller (Volume Control), bei dem durch Druck auf das Stellrad neben der Drehbewegung auch die Funktion eines Tastschalters realisiert ist. Bei der Schwenkbewegung werden die Anschlusskontakte des Bedienelements ebenfalls um die Schwenkachse geschwenkt. Verwendet man zur elektrischen Verbindung des Bedienelements mit der Leiterplatte elektrische Leiter in Form von Litzen oder Drähten, so ergibt sich das Problem, dass durch die Schwenkbewegung die Leitungsverbindung beschädigt werden kann. Um dies zu vermeiden, ist bei der Erfindung eine flexible Leiterplatte vorgesehen, die so bemessen und angeordnet ist, dass diese auch bei sehr häufiger Betätigung der Tastfunktion der mechanischen Beanspruchung standhält. Insbesondere weist die flexible Leiterplatte wenigstens eine Biegezone auf, in der zumindest zum überwiegenden Teil die Biegung der flexiblen Leiterplatte während der Schwenkbewegung stattfindet. Diese Biegezone kann dann so ausgelegt werden, dass auch sehr häufig ausgeführte Schwenkbewegungen des Bedienelements zu keiner Beschädigung der flexiblen Leiterplatte führen.In the invention, an operating element is rotatable about a first axis and formed pivotable about a second axis. For example, the control element is a VC controller (Volume Control), in which by pressing the setting wheel in addition to the rotational movement and the function of a push-button is realized. During the pivoting movement, the connection contacts of the control element are also pivoted about the pivot axis. If electrical conductors in the form of strands or wires are used for the electrical connection of the operating element to the printed circuit board, the problem arises that the line connection can be damaged by the pivoting movement. To avoid this, a flexible printed circuit board is provided in the invention, which is dimensioned and arranged so that it withstands the mechanical stress even with very frequent actuation of the tactile function. In particular, the flexible printed circuit board has at least one bending zone in which, at least for the most part, the bending of the flexible printed circuit board takes place during the pivoting movement. This bending zone can then be designed so that even very often carried out pivoting movements of the control lead to any damage to the flexible circuit board.
Die flexible Leiterplatte umfasst bei der Erfindung vorzugsweise wenigstens zwei Schenkel, wobei der erste Schenkel mit den elektrischen Kontakten des Bedienelements und der zweite Schenkel mit der eigentlichen Leiterplatte des Hörhilfegerätes verbunden sind. Die Biegezone befindet sich vorzugsweise im Übergangsbereich zwischen den beiden Schenkeln.The flexible printed circuit board in the invention preferably comprises at least two legs, wherein the first leg are connected to the electrical contacts of the operating element and the second leg to the actual circuit board of the hearing aid. The bending zone is preferably in the transition region between the two legs.
Um insbesondere bei einem hinter dem Ohr tragbaren Hörhilfegerät eine schlanke Gehäusebauform zu erreichen, bildet der erste Schenkel der flexiblen Leiterplatte eine erste Ebene und der zweite Schenkel der flexiblen Leiterplatte eine zweite Ebene, wobei im in das Hörhilfegerät eingebautem Zustand der flexiblen Leiterplatte die erste Ebene senkrecht zu der zweiten Ebene orientiert ist.In order to achieve a slim housing design, in particular in a hearing aid device that can be worn behind the ear, the first leg of the flexible printed circuit board forms a first plane and the second leg of the flexible printed circuit board forms a second plane, wherein the first plane is perpendicular in the state of the flexible printed circuit board installed in the hearing aid device oriented to the second level.
Bei dem Bedienelement gemäß der Erfindung führt die bei der Betätigung ausgelöste Schwenkbewegung vorzugsweise zur Betätigung eines Miniatur-Tastschalters. Bei einer bevorzugten Ausführungsform der Erfindung ist dieser Miniatur-Tastschalter auf der flexiblen Leiterplatte, z. B. auf dem zweiten Schenkel der flexiblen Leiterplatte angeordnet. Dadurch wird ein besonders platzsparender und kompakter Aufbau des Bedienelements ermöglicht.In the operating element according to the invention, the pivoting movement triggered during the actuation preferably leads to the actuation of a miniature push-button switch. In a preferred embodiment of the invention, this miniature key switch on the flexible circuit board, z. B. on the second leg of the flexible printed circuit board arranged. This allows a particularly space-saving and compact design of the control element.
Die flexible Leiterplatte ist an einem Ende mit der Leiterplatte der Verstärkereinheit des Hörhilfegerätes verbunden. Vorzugsweise bilden die beiden Leiterplatten eine zusammenhängende, einstückige Leiterplatte, so dass keine Kontakte zwischen den Leiterplatten erforderlich sind. Dabei kann die Leiterplatte der Verstärkereinheit ebenfalls flexibel oder auch fest ausgebildet sein. Eine einstückig ausgebildete Leiterplatte reduziert die Anzahl der Bauteile des betreffenden Hörhilfegerätes, reduziert somit Kosten und vereinfacht die Montage.The flexible circuit board is connected at one end to the circuit board of the amplifier unit of the hearing aid. Preferably, the two circuit boards form a continuous, one-piece circuit board, so that no contacts between the circuit boards are required. In this case, the circuit board of the amplifier unit may also be flexible or fixed. An integrally formed printed circuit board reduces the number of components of the hearing aid in question, thus reducing costs and simplifies installation.
Die gemäß der Erfindung vorhandene flexible Leiterplatte kann neben dem ersten und zweiten Schenkel auch wenigstens einen weiteren Schenkel aufweisen, was zu einer Vergrößerung der zur Bestückung von Bauelementen vorhandenen Fläche führt.The existing according to the invention, flexible printed circuit board may also have at least one other leg in addition to the first and second leg, resulting in an increase in the existing surface for mounting components.
Bei einer bevorzugten Ausführungsform der Erfindung ist die flexible Leiterplatte als Polyamid-Folie ausgebildet, die Leiterbahnen umfasst. Die Leiterbahnen befinden sich vorzugsweise zumindest in der Biegezone nicht an einer Oberfläche, sondern innerhalb der flexiblen Leiterplatte, wodurch die mechanische Beanspruchung bei der Biegung reduziert wird.In a preferred embodiment of the invention, the flexible printed circuit board is designed as a polyamide film comprising printed conductors. The conductor tracks are preferably located at least in the bending zone not on a surface, but within the flexible printed circuit board, whereby the mechanical stress during bending is reduced.
