Description

Die vorliegende Erfindung betrifft ein Hörgerät mit einer gedruckten Leiterplatine, die mit elektronischen Signalverarbeitungselementen bestückt ist, und die mindestens eine Anschlusskontaktstelle für einen Audioschuh aufweist, und einem Audioschuh, der mindestens eine Kontaktfeder zum Anschluss an die Leiterplatine aufweist.The present invention relates to a hearing aid with a printed circuit board, which is equipped with electronic signal processing elements, and which has at least one connection pad for an audio shoe, and an audio shoe having at least one contact spring for connection to the printed circuit board.

Zahlreiche Hörgeräte besitzen die Möglichkeit, über einen speziellen Audioschuh Audiosignale einzukoppeln. Hierzu wird in den Audioschuh ein externes Audiogerät eingesteckt. Der Audioschuh bildet dann die Schnittstelle zwischen dem Hörgerät und dem externen Audiogerät.Numerous hearing aids have the option of coupling in audio signals via a special audio shoe. For this purpose, an external audio device is plugged into the audio shoe. The audio shoe then forms the interface between the hearing aid and the external audio device.

Üblicherweise besitzt ein Audioschuh mehrere Kontakte, z. B. vier Stück, die mit entsprechenden Anschlüssen auf der Leiterplatine des Hörgeräts kontaktiert werden müssen. Da sich die Leiterplatine üblicherweise im Mittelbereich des Hörgerätegehäuses befindet, wohingegen der Audioschuh an dem dem Hörer gegenüberliegenden Ende (Batteriefachende) eingesteckt oder angeordnet ist, ist ein spezielles Zwischenstück notwendig, um die Kontakte dieser beiden Elemente zu verbinden. In FIG 1 ist ein derartiges Zwischenstück ZS dargestellt. Es ist an der Leiterplatine LP, die mit Bauelementen zur Signalverarbeitung bestückt ist, kontaktiert.Typically, an audio shoe has multiple contacts, eg. B. four pieces that must be contacted with appropriate connections on the printed circuit board of the hearing aid. Since the printed circuit board is usually in the middle region of the hearing aid housing, whereas the audio shoe is inserted or arranged at the end opposite the listener (battery end), a special intermediate piece is necessary to connect the contacts of these two elements. In FIG. 1 is such an intermediate piece ZS shown. It is contacted on the printed circuit board LP, which is equipped with components for signal processing.

Das Zwischenstück ZS wird meist als Spritzgussteil realisiert. In das Zwischenstück ZS sind Metallkontakte MK eingespritzt oder eingeformt, die dann an der Außenseite des Hörgeräts liegen. Diese Kontakte korrodieren oftmals, so dass es Kontaktprobleme zwischen der Leiterplatine LP und einem in FIG 1 nicht dargestellten Audioschuh gibt. Aus diesem Grund werden in der Regel für den Audioschuh spezielle Abdeckklappen benötigt. Ein weiterer Nachteil des separaten Zwischenstücks ZS besteht darin, dass die Montagezeit für ein Hörgerät durch dieses separate Teil zunimmt.The intermediate piece ZS is usually realized as an injection molded part. In the intermediate piece ZS metal contacts MK are injected or molded, which then lie on the outside of the hearing aid. These contacts often corrode, causing contact problems between the PCB and an LP in FIG. 1 not shown audio shoe. For this reason, special cover flaps are usually required for the audio shoe. Another disadvantage of the separate intermediate piece ZS is that the assembly time for a hearing aid increases by this separate part.

Aus der Druckschrift DD 279 365 A1 ist ein Audioeingang für ein Hörgerät bekannt. Eine mit Schrägen versehene Gehäuseöffnung im Bereich der Schwenkachse der Batterielade wird als Einführungsöffnung für die Kontakte des Audiosteckers benutzt. Die federnden hörgeräteseitigen Kontakte sind auf einer quer stehenden, Bauelemente, wie Schalter und Batteriekontakt, tragenden Platte im Innenraum des Hörgeräts geschützt angeordnet.From the publication DD 279 365 A1 An audio input for a hearing aid is known. A beveled housing opening in the region of the pivot axis of the battery charger is used as an insertion opening for the contacts of the audio plug. The resilient hearing device side contacts are arranged on a transverse, components, such as switches and battery contact, supporting plate protected inside the hearing aid.

Darüber hinaus ist in der Patentschrift US 4 539 439 A ein Hörgerät mit einem externen Mikrofon beschrieben. Das externe Mikrofon wird mit einem Adapter an eine Buchse des Hörgeräts angesteckt. Die Buchse weist eine Platine auf, auf der mehrere Federkontakte aufgelötet sind.In addition, in the patent US 4 539 439A a hearing aid with an external microphone described. The external microphone is plugged with an adapter to a socket of the hearing aid. The socket has a board on which a plurality of spring contacts are soldered.

Die Patentschrift DE 41 09 306 C 1 beschreibt ein Hörgerät mit in einem Batteriefach angeordneten elektrischen Kontaktmitteln. Damit kann ein externes Programmiergerät mit einem programmierbaren Hörgeräteteil verbunden werden.The patent DE 41 09 306 C 1 describes a hearing aid with arranged in a battery compartment electrical contact means. Thus, an external programming device can be connected to a programmable hearing aid part.

Die europäische Patentschrift EP 0 334 837 B1 zeigt ferner ein Hörgerät mit einem Audioschuh. Im Audioschuh befindliche Kontaktfedern stellen Kontakt zu Gehäuseschrauben des Hörgeräts her.The European patent EP 0 334 837 B1 further shows a hearing aid with an audio shoe. Contact springs located in the audio shoe make contact with housing screws of the hearing aid.

Darüber hinaus offenbaren die Druckschriften WO 2004/112431 A1 , EP 1 346 602 B1 und CH 675 657 A5 jeweils Hörgeräte mit einem abnehmbaren Audioschuh. Die Kontakte des Audioschuhs werden mit entsprechenden Gegenkontakten am Hörgerätegehäuse verbunden.In addition, the pamphlets reveal WO 2004/112431 A1 . EP 1 346 602 B1 and CH 675 657 A5 each hearing aid with a removable audio shoe. The contacts of the audio shoe are connected to corresponding mating contacts on the hearing aid housing.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, die Montage eines Hörgeräts, an das ein Audioschuh anschließbar ist, zu vereinfachen und die Störanfälligkeit des Kontakts zwischen Audioschuh und der Leiterplatte zu reduzieren. Erfindungsgemäß wird diese Aufgabe gelöst durch ein Hörgerät mit einer gedruckten Leiterplatine, die mit elektronischen Signalverarbeitungselementen zur Signalverstärkung bestückt ist, und die mindestens eine Anschlusskontaktstelle für einen Audioschuh aufweist, und einem Audioschuh, der mindestens eine Kontaktfeder zum Anschluss an die Leiterplatine aufweist, wobei die mindestens eine Kontaktfeder derart gestaltet ist, dass sie die mindestens eine Anschlusskontaktstelle direkt berührt.The object of the present invention is thus to simplify the installation of a hearing device to which an audio shoe can be connected and to reduce the susceptibility of the contact between the audio shoe and the printed circuit board. According to the invention this object is achieved by a hearing aid with a printed circuit board, which is equipped with electronic signal processing elements for signal amplification, and having at least one terminal pad for an audio shoe, and an audio shoe having at least one contact spring for connection to the printed circuit board, wherein the at least a contact spring is designed such that it touches the at least one terminal contact point directly.

In vorteilhafter Weise kann durch die spezielle(n) Kontaktfeder (n) auf ein teures mit Leiterbahnen versehenes Kunststoffteil verzichtet werden. Damit entfallen auch Korrosionsprobleme, die mit den sonst üblichen Zwischenstücken aufgetreten sind. Darüber hinaus entfällt auch der verhältnismäßig aufwendige Montageschritt, dass Leiterbahnen für den Audioschuh an die Leiterplatine des Hörgeräts angelötet werden müssen, um die Kontaktsicherheit zwischen diesen beiden Komponenten zu erhöhen.Advantageously, can be dispensed with by the special (n) contact spring (s) on an expensive provided with conductor tracks plastic part. This eliminates corrosion problems that have occurred with the usual spacers. In addition, eliminates the relatively expensive assembly step that traces for the audio shoe must be soldered to the printed circuit board of the hearing aid in order to increase the contact reliability between these two components.

Vorzugsweise weist der Audioschuh eine Batteriehalteeinrichtung auf und ist in ein Batteriefach des Hörgeräts zumindest teilweise einsteckbar. Dadurch kann eine stabile mechanische Verbindung zwischen dem Hörgerät und dem Audioschuh erzielt werden.Preferably, the audio shoe on a battery holding device and is at least partially inserted into a battery compartment of the hearing aid. As a result, a stable mechanical connection between the hearing aid and the audio shoe can be achieved.

Die mindestens eine Kontaktfeder ist in vorteilhafter Weise durch die Batteriehalteeinrichtung gestützt. Dadurch gewährleisten die Kontaktfedern trotz ihrer verhältnismäßig großen Länge eine hinreichende Kontaktkraft gegenüber der Leiterplatine des Hörgeräts.The at least one contact spring is supported by the battery holding device in an advantageous manner. As a result, the contact springs ensure a sufficient contact force against the printed circuit board of the hearing aid despite their relatively long length.

Die mindestens eine Kontaktfeder kann teilweise in die Batteriehalteeinrichtung eingegossen sein. Dadurch lassen sich die Kontaktfedern in ihrer Lage sehr gut stabilisieren.The at least one contact spring may be partially molded into the battery holding device. This allows the contact springs to stabilize very well in their position.

Darüber hinaus kann der Audioschuh eine Abdeckung des Batteriefachs des Hörgeräts darstellen. Damit kann auf eine separate Abdeckung verzichtet werden, wenn ein Audioschuh eingesetzt wird.In addition, the audio shoe can represent a cover of the battery compartment of the hearing aid. This can be dispensed with a separate cover when an audio shoe is used.

Bei einer besonders günstigen Ausführungsform ist der Audioschuh fest an das Hörgerät installiert. Damit kann der Nutzer stets ein externes Audiogerät an sein Hörgerät anschließen, ohne hierzu einen speziellen Adapter bereithalten oder suchen zu müssen.In a particularly favorable embodiment of the audio shoe is firmly installed on the hearing aid. Thus, the user can always connect an external audio device to his hearing aid, without having to hold a special adapter or search for it.

Die vorliegende Erfindung wird nun anhand der beigefügten Zeichnungen näher erläutert, in denen zeigen:

eine Ansicht einer Leiterplatine mit einem Zwischenstück zur Kontaktierung eines Audioschuhs gemäß dem Stand der Technik;
FIG 2
ein Hörgerät mit erfindungsgemäßem Audioschuh;
FIG 3
eine Detailansicht des Verbindungsbereichs der Kontaktfedern mit der Leiterplatine; und
FIG 4
eine 3D-Ansicht eines erfindungsgemäßen Audioschuhs.
The present invention will now be explained in more detail with reference to the accompanying drawings, in which:
FIG. 1
a view of a printed circuit board with an intermediate piece for contacting an audio shoe according to the prior art;
FIG. 2
a hearing aid with audio shoe according to the invention;
FIG. 3
a detailed view of the connecting portion of the contact springs with the printed circuit board; and
FIG. 4
a 3D view of an audio shoe according to the invention.

Das nachfolgend näher geschilderte Ausführungsbeispiel stellt eine bevorzugte Ausführungsform der vorliegenden Erfindung dar.The embodiment described in more detail below represents a preferred embodiment of the present invention.

Entsprechend FIG 2 ist ein erfindungsgemäßes Hinter-dem-Ohr-Hörgerät HG an dem dem Tragehaken TH abwandten Ende mit einem Audioschuh AS ausgestattet. In dem Bild von FIG 2 ist ferner eine Batterie BA und eine bestückte Leiterplatine LP zu erkennen. Kontaktfedern KF stellen den Kontakt zwischen dem Audioschuh AS und der Leiterplatine LP her.Corresponding FIG. 2 a behind-the-ear hearing aid HG according to the invention is equipped with an audio shoe AS on the end facing away from the wearing hook TH. In the picture of FIG. 2 Furthermore, a battery BA and a populated printed circuit board LP can be seen. Contact springs KF establish contact between the audio shoe AS and the printed circuit board LP.

Der Audioschuh AS ist somit direkt in das Hörgerätegehäuse montiert bzw. integriert. Dies bedeutet, dass der Audioschuh nicht wie sonst üblich vom Hörgerät auf- und abgenommen werden kann. In einer alternativen Ausführungsform kann der Audioschuh natürlich nach wie vor steckbar realisiert sein. In beiden Fällen kann das Hörgerät im Normalmodus oder im Audioschuhmodus betrieben werden.The audio shoe AS is thus mounted or integrated directly into the hearing aid housing. This means that the audio shoe can not be attached and removed by the hearing aid as usual. Of course, in an alternative embodiment, the audio shoe can still be implemented pluggable. In both cases, the hearing aid can be operated in normal mode or in audio shoe mode.

In FIG 3 ist der Ausschnitt von FIG 2 vergrößert dargestellt, der den Verbindungsbereich zwischen den Kontaktfedern KF und der Leiterplatine LP zeigt. In der Figur sind jedoch nur drei von vier Kontaktfedern direkt erkennbar. Eine vierte Kontaktfeder ist schematisch im Hintergrund zu erkennen. Die Kontaktfedern KF sind in einen Batteriehalteabschnitt BH eingegossen. Dadurch wird der federnde Abschnitt der relativ langen Kontaktfedern (vgl. FIG 2) kurz gehalten, so dass eine entsprechend hohe Federkraft am Ende der Kontaktfedern KF erzielt werden kann.In FIG. 3 is the section of FIG. 2 shown enlarged, showing the connection area between the contact springs KF and the printed circuit board LP. In the figure, however, only three out of four contact springs are directly recognizable. A fourth contact spring can be seen schematically in the background. The contact springs KF are cast in a battery holding portion BH. As a result, the resilient portion of the relatively long contact springs (see. FIG. 2 ) kept short so that one correspondingly high spring force at the end of the contact springs KF can be achieved.

An der Unterseite der Leiterplatine LP sind entsprechend vier Kontaktbereiche KB, sogenannte Kontakt-Pads, vorgesehen. Von den vier Kontaktbereichen sind in FIG 3 lediglich drei erkennbar und der Ort des vierten lediglich durch eine Bezugslinie angedeutet.On the underside of the printed circuit board LP are correspondingly four contact areas KB, so-called contact pads, provided. Of the four contact areas are in FIG. 3 only three visible and the location of the fourth indicated only by a reference line.

Nach der Montage des Audioschuhs AS an das Hörgerät HG drücken die vier Kontaktfedern KF des Audioschuhs AS jeweils unmittelbar an die jeweiligen Kontaktbereiche KB der Leiterplatine LP. Dadurch kann auf ein spezielles Zwischenstück zwischen dem Audioschuh AS und der Leiterplatine LP verzichtet werden, das gegebenenfalls Kontaktprobleme verursacht.After the audio shoe AS has been mounted on the hearing aid HG, the four contact springs KF of the audio shoe AS each press directly against the respective contact areas KB of the printed circuit board LP. As a result, it is possible to dispense with a special intermediate piece between the audio shoe AS and the printed circuit board LP, which possibly causes contact problems.

FIG 4 zeigt den Audioschuh AS in dem vom Hörgerät HG entnommenen Zustand. Der Audioschuh AS besteht aus einem Kunststoffgebilde, das unter anderem aus dem Batteriehalter BH besteht. In den Batteriehalter BH sind die vier Kontaktfedern KF teilweise eingegossen, wobei ihre Enden frei sind. FIG. 4 shows the audio shoe AS in the state removed by the hearing aid HG. The audio shoe AS consists of a plastic structure, which consists inter alia of the battery holder BH. In the battery holder BH, the four contact springs KF are partially molded, with their ends are free.

Der Batteriehalter BH wird bei der Montage des Audioschuhs an das Hörgerät in das Batteriefach des Hörgeräts eingeführt. Der Audioschuh AS bzw. der Teil des Audioschuhs mit der Kontaktschnittstelle KS bildet dann den Batteriefachdeckel. Somit vereint der erfindungsgemäße Audioschuh, wie er in FIG 4 dargestellt ist, die vier Funktionalitäten: Audioschuh, Zwischenstück, Batteriehalter und Batteriefachdeckel.The battery holder BH is inserted in the mounting of the audio shoe to the hearing aid in the battery compartment of the hearing aid. The audio shoe AS or the part of the audio shoe with the contact interface KS then forms the battery compartment cover. Thus, the audio shoe according to the invention, as in FIG. 4 The four functionalities are shown: audio shoe, adapter, battery holder and battery compartment cover.
