Definitions
- the invention relates to a hearing aid for the hearing impaired, in particular to behind-the-ear device, with a hearing device parts, such as a microphone, amplifier, earpiece, battery, etc., housing, the parts of which are held together by releasable connecting elements, such as screws, and with an audio input connector.
- a hearing device parts such as a microphone, amplifier, earpiece, battery, etc., housing, the parts of which are held together by releasable connecting elements, such as screws, and with an audio input connector.
- the audio input is an electrical contact device, via which a sound-frequency electrical signal can be directly - galvanically - fed into the hearing aid amplifier.
- the audio input is often used in schools for the hearing impaired in connection with a "frequent hearing facility" or with FM or infrared transmission systems and the like. But also in the private area the hearing impaired can be used by many additional devices such as hand microphones, TV Adapters, portable cassette players, etc., which can be connected to the audio input, benefit.
- the audio input is a contact device that enables the connection of the output cable of an external signal source either via a pin / socket combination or via a pressure contact.
- the so-called "audio shoe” was proposed as a way out of this situation. It is a cup-like structure that clamps or snaps around the lower part of the hearing aid. On the inside, the audio shoe has contact springs which are in line with the individual contact devices of the hearing aid in question, and on the outside there is a socket for two or three sockets has a standard Euro audio plug.
- Such an audio shoe is described for example in DE-PS 27 51 755. However, a special manufacturer-specific audio shoe is required for each hearing aid type.
- the object of the invention is to provide a hearing aid of the type mentioned at the outset which eliminates the disadvantages described.
- the audio input connection takes place via at least two of the connecting elements holding the detachable housing parts together.
- the invention thus proposes to use at least two of the connecting elements that are present anyway, such as screws, by means of which the two halves of the device housing are held together, as a contact device for the audio input.
- This solution has the advantage that no special housing and no additional space for the contact device is required. Furthermore, when the audio shoe is removed, no components that increase the dimensions of the device are required.
- Fig. 1 shows schematically a BTE device housing, which as usual consists of two shell halves (1, 2) and is held together by the screws (3, 4, 5), of which the screws (3, 4) as connections for the audio - Entrance can be used.
- FIG. 2 shows in detail a sectional view of the inner construction of the housing in the area of one of the connecting elements 3 or 4.
- a metallic stud 6 with an internal thread is injected into the lower shell 2.
- a screw 3, which holds the upper shell 1, is screwed into this.
- the stud 6 can be molded with the lower shell 2 and in this case is made of plastic.
- the screw 3 In order to be able to use the screw 3 as a contact for an attached audio shoe, it is necessary to electrically connect the stud 6 to the circuit of the hearing aid. This is done with the aid of a compression spring 8, which in turn is attached to the amplifier board 7 by riveting or soldering. If there is no space for this, you can contact the stud 6 - or in the event that this is made of plastic, the screw 3 itself - with the help of a hairpin-like fork spring.
- a connecting wire 10 can be soldered to the fork spring 9. Direct soldering to the stud is generally not advisable, since there is a risk of the housing being damaged by the soldering heat. You can also weld the connecting wire 10 - as a non-releasable connection - to the bolt 6.
- Fig. 4 shows in section a part of the housing in the area of the connecting element with an attached audio shoe 11.
- the shoe 11 contains resilient sleeves 12 for the euro audio connector, which make a connection to the housing screws via attached contact springs 13.
- the head of the screw serving as contact is conical and the end of the contact spring 14 has the shape of a spherical cap. These two parts then form a clean, self-cleaning contact when the audio shoe is placed on the hearing aid.
- the housing is therefore not damaged by the contact springs. It is also advantageous to at least lower the screw heads serving as contacts so far in the housing 1 that they cannot make contact with the skin of the hearing device wearer in the use position of the device in order to avoid undesired electrical effects or interference if no audio shoe is fitted is.
- the resulting recesses in the housing can serve in cooperation with the spherical end of the contact springs 14 as a locking device for the entire audio shoe 11.

Description
Die Erfindung betrifft ein Hörgerät für Schwerhörige, insbesonders an Hinter-Ohr-Gerät, mit einem Hörgeräteteile, wie etwa Mikrofon, Verstärker, Hörer, Batterie etc., aufnehmenden Gehäuse, dessen Teile durch lösbare Verbindungselemente, wie etwa Schrauben, zusammengehalten sind, und mit einem Audio-Eingangs-Anschluß.The invention relates to a hearing aid for the hearing impaired, in particular to behind-the-ear device, with a hearing device parts, such as a microphone, amplifier, earpiece, battery, etc., housing, the parts of which are held together by releasable connecting elements, such as screws, and with an audio input connector.
Der Audio-Eingang ist eine elektrische Kontaktvorrichtung, über die ein tonfrequentes elektrisches Signal direkt -galvanisch- in den Hörgeräteverstärker eingespeist werden kann. Verwendung findet der Audio-Eingang vielfach in Schwerhörigen-Schulen in Verbindung mit einer "Vielhör-Einrichtung" oder mit FM- oder Infrarot-Übertragungsanlagen u.dgl.. Aber auch im privaten Bereich kann der Schwerhörige von vielen Zusatzeinrichtungen, wie Handmikrofone, TV-Adapter, tragbare Kasettenspieler etc. profitieren, die sich an den Audio-Eingang anschließen lassen.The audio input is an electrical contact device, via which a sound-frequency electrical signal can be directly - galvanically - fed into the hearing aid amplifier. The audio input is often used in schools for the hearing impaired in connection with a "frequent hearing facility" or with FM or infrared transmission systems and the like. But also in the private area the hearing impaired can be used by many additional devices such as hand microphones, TV Adapters, portable cassette players, etc., which can be connected to the audio input, benefit.
Elektrisch gesehen ist der Audio-Eingang eine Kontaktvorrichtung, die entweder über eine Stift/Büchse-Kombination oder über einen Druckkontakt den Anschluß des Ausgangskabels einer externen Signalquelle ermöglicht.Electrically speaking, the audio input is a contact device that enables the connection of the output cable of an external signal source either via a pin / socket combination or via a pressure contact.
Bedingt durch den notorischen Platzmangel in modernen Hinter-Ohr-Geräten sind die Kontaktvorrichtungen von Fabrikat zu Fabrikat und oft sogar von Modell zu Modell eines einzelnen Herstellers sehr verschieden. Dies hat insbesonders in Schwerhörigen-Schulen zu einer unvorstellbar hohen Anzahl verschiedener Stecker und Kabel geführt.Due to the notorious lack of space in modern behind-the-ear devices, the contact devices differ from brand to brand and often even from model to model from a single manufacturer. This has led to an unimaginably high number of different plugs and cables, especially in schools for the hard of hearing.
Als Ausweg aus dieser Situation wurde der sogenannte "Audio-Schuh" vorgeschlagen. Es ist dies ein becherartiges Gebilde, das den unteren Teil des Hörgerätes klemmend oder rastend umschließt. An seiner Innenseite hat der Audio-Schuh Kontaktfedern, die mit den individuellen Kontaktvorrichtungen des betreffenden Hörgerätes in Einklang stehen, und an seiner Außenseite eine aus zwei oder drei Buchsen bestehende Steckdose für einen genormten Euro-Audiostecker aufweist. Ein derartiger Audio-Schuh ist etwa in der DE-PS 27 51 755 beschrieben. Dabei ist jedoch für jeden Hörgeräte-Typ ein spezieller herstellerspezifischer Audio-Schuh nötig.The so-called "audio shoe" was proposed as a way out of this situation. It is a cup-like structure that clamps or snaps around the lower part of the hearing aid. On the inside, the audio shoe has contact springs which are in line with the individual contact devices of the hearing aid in question, and on the outside there is a socket for two or three sockets has a standard Euro audio plug. Such an audio shoe is described for example in DE-PS 27 51 755. However, a special manufacturer-specific audio shoe is required for each hearing aid type.
Auf Grund der laufenden Miniaturisierung aller Einzelteile werden auch Hinter-Ohr-Hörgeräte immer kleiner, sodaß sich in modernsten Miniatur-Konstruktionen aber immer seltener noch Platz für die Kontaktvorrichtung für einen Audio-Eingang findet. Dies hat dazu geführt, daß heute zahlreiche Miniatur-Hör-Geräte ohen Audio-Eingang am Markt sind, die gerade für Kinder besonders geeignet wären, aber von diesen nur eingeschränkt benützt werden können. Einen Ausweg bieten hier noch etwa Lösungen gemäß dem DE-GM 83 19 075, wo vorgeschlagen wird, die Steckvorrichtung für den Audio-Eingang in Form eines "Rucksacks" außen am Gerät anzuhängen. Diese Lösung ist aber wenig attraktiv, weil sie das Gerät insgesamt vergrößert und der Rucksack ja auch dann vorhanden ist, wenn der Audio-Eingang nicht benötigt wird.Due to the ongoing miniaturization of all individual parts, even behind-the-ear hearing aids are getting smaller, so that there is less and less space for the contact device for an audio input in the most modern miniature constructions. This has resulted in numerous miniature hearing aids with no audio input on the market today, which would be particularly suitable for children, but can only be used by them to a limited extent. Solutions according to DE-GM 83 19 075, where it is proposed to attach the plug-in device for the audio input in the form of a "backpack" on the outside of the device, offer a way out. However, this solution is not very attractive because it enlarges the device as a whole and the backpack is also available when the audio input is not required.
Aufgabe der Erfindung ist es, ein Hörgerät der eingangs angeführten Art zu schaffen, welches die beschriebenen Nachteile beseitigt.The object of the invention is to provide a hearing aid of the type mentioned at the outset which eliminates the disadvantages described.
Dies wird erfindungsgemäß dadurch erreicht, daß der Audio-Eingangs-Anschluß über mindestens zwei der die lösbaren Gehäuseteile zusammenhaltenden Verbindungselemente erfolgt.This is achieved according to the invention in that the audio input connection takes place via at least two of the connecting elements holding the detachable housing parts together.
Die Erfindung schlägt somit vor, mindestens zwei der ohnehin vorhandenen Verbindungselemente, etwa Schrauben, mit deren Hilfe die beiden Hälften des Geräte-Gehäuses zusammengehalten werden, als Kontaktvorrichtung für den Audio-Eingang zu benützen.The invention thus proposes to use at least two of the connecting elements that are present anyway, such as screws, by means of which the two halves of the device housing are held together, as a contact device for the audio input.
Diese Lösung hat den Vorteil, daß kein spezielles Gehäuse und keinerlei zusätzlicher Platz für die Kontaktvorrichtung benötigt wird. Weiters benötigt man bei abgezogenem Audio-Schuh keine die Abmessungen des Gerätes vergrößernden Bauteile.This solution has the advantage that no special housing and no additional space for the contact device is required. Furthermore, when the audio shoe is removed, no components that increase the dimensions of the device are required.
Die Erfindung wird nun näher unter Bezugnahme auf die Zeichnungen beschrieben. In den Zeichnungen zeigen:
- Fig. 1 eine perspektivische Ansicht eines HdO-Hörgerätes, bei welchem erfindungsgemäße Audio-Eingangs-Anschlüsse vorgesehen werden können;
- Fig. 2 einen Schnitt durch das Hörgerätegehäuse im Bereich der Verbindungselemente;
- Fig. 3 eine Draufsicht auf die untere Gehäuseschale mit einem gabelförmigen Anschlußkontakt;
- Fig. 4 einen Schnitt durch einen Teil eines Hörgerätegehäuses mit einem aufgesetzten Audio-Schuh.
- 1 shows a perspective view of a BTE hearing aid in which audio input connections according to the invention can be provided;
- 2 shows a section through the hearing aid housing in the region of the connecting elements;
- 3 shows a plan view of the lower housing shell with a fork-shaped connection contact;
- Fig. 4 shows a section through part of a hearing aid housing with an attached audio shoe.
Fig. 1 zeigt schematisch ein HdO-Gerätegehäuse, das wie üblich aus zwei Schalenhälften (1, 2) besteht und durch die Schrauben (3, 4, 5) zusammengehalten wird, wovon etwa die Schrauben (3, 4) als Anschlüsse für den Audio-Eingang benützt werden.Fig. 1 shows schematically a BTE device housing, which as usual consists of two shell halves (1, 2) and is held together by the screws (3, 4, 5), of which the screws (3, 4) as connections for the audio - Entrance can be used.
Fig. 2 zeigt im Detail eine Schnittansicht der Innenkonstruktion des Gehäuses im Bereich eines der Verbindungselemente 3 oder 4. In die untere Schale 2 ist ein metallischer Stehbolzen 6 mit Innengewinde eingespritzt. In dieses wird eine Schraube 3 eingedreht, die die obere Schale 1 festhält. Der Stehbolzen 6 kann mit der Unterschale 2 mitgespritzt sein und besteht in diesem Fall aus Kunststoff.2 shows in detail a sectional view of the inner construction of the housing in the area of one of the connecting
Um die Schraube 3 als Kontakt für einen aufgesteckten Audio-Schuh verwenden zu können, ist es notwendig, den Stehbolzen 6 elektrisch mit der Schaltung des Hörgerätes zu verbinden. Dies erfolgt mit Hilfe einer Druckfeder 8, die ihrerseits auf der Verstärkerplatine 7 durch Nieten oder Löten befestigt ist. Ist dafür kein Platz vorhanden, kann man den Stehbolzen 6 - oder für den Fall, daß dieser aus Kunststoff besteht, die Schraube 3 selbst - mit Hilfe einer haarnadelähnlichen Gabelfeder kontaktieren.In order to be able to use the
Fig. 3 zeigt eine solche Lösung als Draufsicht auf die Unterschale 2. An die Gabelfeder 9 kann ein Anschlußdraht 10 angelötet werden. Ein direktes Löten an dem Stehbolzen ist in der Regel nicht zweckmäßig, da die Gefahr einer Beschädigung des Gehäuses durch die Löthitze gegeben ist. Man kann den Anschlußdraht 10 auch - als nicht lösbare Verbindung - an den Bolzen 6 anschweißen.3 shows such a solution as a top view of the
Fig. 4 zeigt im Schnitt einen Teil des Gehäuses im Bereich des Verbindungselementes mit einem aufgesetzten Audio-Schuh 11. Der Schuh 11 enthält federnde Büchsen 12 für den Euro-Audiostecker, die über daran befestigte Kontaktfedern 13 eine Verbindung zu den Gehäuseschrauben herstellen.Fig. 4 shows in section a part of the housing in the area of the connecting element with an attached
Es hat sich als vorteilhaft herausgestellt, wenn der Kopf der als Kontakt dienenden Schraube kegelförmig ist und das Ende der Kontaktfeder 14 die Form einer Kugelkalotte hat. Diese beiden Teile bilden beim Aufsetzen des Audio-Schuhs auf das Hörgerät dann einen sauberen, selbstreinigenden Kontakt. Das Gehäuse wird daher durch die Kontaktfedern nicht beschädigt. Es ist weiters vorteilhaft, zumindest die als Kontakte dienenden Schraubenköpfe soweit im Gehäuse 1 zu versenken, daß sie in Gebrauchslage des Gerätes keinen Kontakt zur Haut des Hörgeräte-Trägers machen können, um unerwünschte elektrische Effekte oder Einstreuungen zu vermeiden, wenn kein Audio-Schuh aufgesetzt ist.It has turned out to be advantageous if the head of the screw serving as contact is conical and the end of the
Die auf diese Weise entstehenden Vertiefungen im Gehäuse können in Zusammenwirken mit dem kugeligen Ende der Kontaktfedern 14 gleich als Rastvorrichtung für den ganzen Audio-Schuh 11 dienen.The resulting recesses in the housing can serve in cooperation with the spherical end of the
Natürlich ist auch eine getrennte Rastvorrichtung möglich. Als die Gehäuseteile zusammenhaltende Verbindungselemente können neben den üblicherweise verwendeten Schrauben auch andere bekannte Ausführungsformen, wie etwa Rastelemente verwendet werden. Mikrofon, Verstärker, Hörer, Batterie, Bedienungselemente etc. sind in den Abbildungen nicht dargestellt, da sie für die vorliegende Erfindung nicht wesentlich sind. Diese Teile sind entsprechend dem Stand der Technik im Gehäuse bzw. an dessen Außenseite untergebracht.Of course, a separate locking device is also possible. In addition to the screws commonly used, other known embodiments, such as latching elements, can be used as the connecting elements holding the housing parts together. Microphone, amplifier, handset, battery, operating elements etc. are not shown in the figures since they are not essential for the present invention. These parts are accommodated in the housing or on the outside thereof in accordance with the prior art.
