Die vorliegende Erfindung betrifft ein Hinterohr-Hörgerät nach dem Oberbegriff von Anspruch 1.The present invention relates to a behind-the-ear hearing aid the preamble of claim 1.

Bei derartigen Hörgeräten ist es üblich, den Gerätekörper mit einem rohrförmig gebogenen Gehäuseteil aufzubauen, welches im wesentlichen entlang Mantellinien geteilt ist, in zwei Schalen. Die Assemblierung erfolgt durch Öffnen der Schalen, Einlegen der dem Hörgerät zugehörigen Funktionseinheiten und Verschliessen der Schalen, sei dies durch Verkleben oder Verschrauben. Dies erfordert gut ausgebildetes Personal und präzise Arbeit, sowohl was das Einlegen der erwähnten Funktionseinheiten anbelangt, wie auch deren elektrische Kontaktierung, oft durch Löten, und schliesslich, was das Verschliessen der Schalen anbelangt. Zudem ergeben sich entlang der verbundenen Schalen Verbindungsstellen, die bezüglich Dichtheit kritisch sind.In such hearing aids, it is customary with the device body to build a tubular curved housing part, which in essentially divided along generatrices, in two shells. The assembly takes place by opening the trays, inserting the functional units and closures associated with the hearing aid the shells, either by gluing or screwing. This requires well-trained staff and precise work, as far as the insertion of the mentioned functional units is concerned, as well as their electrical contact, often by soldering, and finally, as far as the closure of the bowls is concerned. In addition, connecting points arise along the connected shells, which are critical in terms of tightness.

Die vorliegende Erfindung bezweckt, diese Nachteile zu beheben. Zu diesem Zweck zeichnet sich das eingangs genannte Hörgerät nach dem Kennzeichen von Anspruch 1 aus.The present invention aims to remedy these disadvantages. For this purpose, the above-mentioned hearing aid is characterized according to the characterizing part of claim 1.

Demnach umfasst der Gerätekörper einen einteiligen, mindestens zum Teil rohrförmig geschlossenen Gehäuseteil. Damit entfallen die obgenannte Verbindungsstellen, und wie sich nun ohne weiteres ergibt, muss und kann das Assemblieren durch axiales Einschieben der Funktionseinheiten in den rohrförmigen Teil erfolgen, wobei bevorzugterweise eine durchwegs lötfreie elektrische Kontaktierung erfolgt. Dieses Assemblierungsverfahren, dessen Basis das erfindungsgemäss vorgesehene, einteilige, rohrförmig geschlossene Gehäuseteil ist, eignet sich im Unterschied zu vorbekannten Assemblierungsverfahren äusserst gut für eine Automatisierung. Accordingly, the device body comprises a one-piece, at least partly tubular closed housing part. This accounts the aforementioned connection points, and how now easily results, must and can be assembled by axial insertion the functional units take place in the tubular part, wherein preferably a consistently solderless electrical Contacting takes place. This assembly method, whose Base the invention provided, one-piece, tubular closed housing part is, unlike Previously known assembly process extremely good for automation.

In einer bevorzugten Ausführungsform des Hörgerätes wird der Gehäuseteil in einem Abschnitt mittels eines Deckels zu einem im wesentlichen über seine ganze Länge geschlossenen Rohr komplettiert. Bevorzugterweise wird dabei der Innenraum mit Aufnahmen für das gestapelte, geführte Einlegen von im Gerät aufzunehmenden Baueinheiten ausgebildet.In a preferred embodiment of the hearing aid is the Housing part in a section by means of a lid to a completed substantially over its entire length closed tube. Preferably, while the interior with shots for the stacked, guided insertion of in the device to be included Building units formed.

Auf der einen Seite des erwähnten Gehäuseteils ist ein akustischer Auskopplungsstutzen, vorzugsweise lösbar, angeordnet, das andere Ende wird durch einen vorzugsweise zerstörungsfrei entfernbaren Deckel verschlossen, zu einem Aufnahmefach mit mindestens zwei elektrischen Kontakten. Weitere am erwähnten Geräteteil vorgesehene Organe, wie die beiden erwähnten Deckel, Bedienungsschalter, Auskopplungsstutzen etc. sind bevorzugt dichtend am Geräteteil angeordnet.On one side of the mentioned housing part is an acoustic Auskopplungsstutzen, preferably detachably arranged, the other end is replaced by a preferably non-destructive Cover closed, to a receptacle with at least two electrical contacts. Further on the mentioned device part provided organs, such as the two covers mentioned, Discharge nozzles, etc. are preferably sealing arranged on the device part.

In Fig. 1 ist in teilweise vereinfachter Längsschnitt-Darstellung das erfindungsgemässe Hinterohr-Hörgerät als Ganzes dargestellt, woran vorerst die einzelnen Funktionsblöcke bzw. Funktionsteile beschrieben werden sollen. Das Hörgerät 1 umfasst einen hornförmig gebogenen, rohrförmigen Grundkörper mit einer Zentrumsachse A, welcher am dünneren, umgebogenen Ende, als akustischer Ausgang, einen Anschlussstutzen 5 für ein ins Ohr führendes Kopplungsrohr aufweist. Der Anschlussstutzen 5 ist auswechselbar auf einem Rohrstutzen 9, der an einem Grundgehäuse 3 sitzt, aufgesteckt oder aufgeschraubt.In Fig. 1 is a partially simplified longitudinal sectional view the inventive behind-the-ear hearing aid as a whole what the individual function blocks or Function parts to be described. The hearing aid 1 comprises a horn-shaped curved tubular body with a center axis A, which at the thinner, bent end, as an acoustic output, a connecting piece 5 for a ins Ear has leading coupling tube. The connecting piece 5 is replaceable on a pipe socket 9, on a basic housing 3 sits, plugged or screwed.

Der Innenkanal 7 des Anschlussstutzens 5 setzt sich durch den Rohrstutzen 9 fort in einen Übertragungskanal 11 im Grundgehäuse 3. Der Übertragungskanal 11 seinerseits ist an eine elektrisch/akustische Wandleranordnung 15 in einem Abteil 13 des Grundgehäuses 3 angekoppelt.The inner channel 7 of the connecting piece 5 is replaced by the Pipe socket 9 fort in a transmission channel 11 in the base housing 3. The transmission channel 11 in turn is connected to an electrical / acoustic Transducer assembly 15 in a compartment 13 of the Basic housing 3 docked.

Wie aus Fig. 1 ersichtlich, erstreckt sich der Übertragungskanal 11 entlang der Innenkrümmung des Grundgehäuses 3 derart, dass Aussenkrümmungs-seitig eine Mikrophonbaueinheit 17 Platz findet. Am Grundgehäuse 3 ist in diesem Bereich ein Deckel 19 eingeformt und im Bereiche des Kulminationspunktes des Gerätes mittels einer Steckachse 21 arretiert. Wie insbesondere in Fig. 2 ersichtlich, erstreckt sich der Deckel 19 entlang Mantellinien M des Gerätekörpers, bis, Fig. 1, in den Bereich der elektro/akustischen Wandler-Einheit 15. Die Mikrophonbaueinheit 17 ist bei Entfernen des Klappdeckels 19 zugänglich und vorzugsweise lediglich an einer Flexprint-Lasche (nicht dargestellt) elektrisch kontaktiert, über den Übertragungskanal 11 geklappt und liegt an einem Schalleintrittsschlitz 23.As can be seen from Fig. 1, the transmission channel extends 11 along the inner curvature of the base housing 3 in such a way that outside curvature side a microphone unit 17 place place. At the base housing 3 is in this area a lid 19th molded and in the areas of the culminating point of the device locked by means of a thru-axle 21. As in particular in FIG. 2, the lid 19 extends along generatrices M of the device body, to, Fig. 1, in the field of electro / acoustic Transducer Unit 15. The Microphone Unit 17 is accessible upon removal of the hinged lid 19 and preferably only on a Flexprint tab (not shown) electrically contacted, folded over the transmission channel 11 and is located at a sound entry slot 23.

Bei geschlossenem Deckel 19 liegen mindestens zwei vorgesehene Mikronphonöffnungen der Mikrophonbaueinheit 17 einer Einlage 25 in einem Schlitz 23 des Deckels 19 gegenüber. Die Einlage 25 ist akustisch "transparent" und weist eine Vielzahl Durchtritte zwischen der Umgebung U und einem Ausgleichsvolumen V auf, welch letzteres zwischen den (nicht dargestellten) diskreten Mikrophon-Eintrittsöffnungen und besagter Einlage freigelassen ist. Bevorzugterweise ist die Einlage 25 hierzu aus einem gesinterten Material gefertigt, wie insbesondere aus gesintertem Polyethylen und dabei weiter bevorzugt wasserabstossend beschichtet. Es bildet weiter eine Gitterfeinheit zwischen 10 µm und 200 µm mit einer Offenporigkeit bevorzugt von über 70 %. Im weiteren sind Mikrophonbaueinheit 17 und Einlage 25 im Schlitz 23 so am Hörgerät 1 angeordnet, dass sie, bei getragenem Hörgerät, möglichst keinem Luftstaudruck der Umgebung U ausgesetzt sind, indem sie - wie aus Fig. 1 ersichtlich - im Bereich der Kuppe des hornförmig gebogenen, rohrförmigen Grundkörpers positioniert sind. Insbesondere bei Realisation eines akustisch/elektrischen Wandlers mit Richtcharakteristik mit Hilfe der erwähnten mindestens zwei beabstandeten Mikrophone wird durch das vorgesehene Zwischenvolumen V, im Sinne einer "common mode"-Unterdrückung, erreicht, dass sich entlang der Einlage 25 unterschiedlich eingekoppelte, gleiche akustische Signale aufgrund der Ausgleichswirkung des Volumens V tendenziell aufheben.When the lid 19 is closed at least two provided Micronphone openings of the microphone assembly 17 of a liner 25 in a slot 23 of the lid 19 opposite. The insert 25 is acoustically "transparent" and has a multitude of passages between the environment U and a compensation volume V, which latter between the discrete (not shown) Microphone entry openings and said deposit released is. Preferably, the insert 25 is for this purpose from a made of sintered material, such as sintered in particular Polyethylene and thereby more preferably water repellent coated. It further forms a mesh fineness between 10 microns and 200 microns with an open porosity preferably of over 70%. in the further are microphone assembly 17 and insert 25 in the slot 23 arranged on the hearing aid 1, that they, with worn hearing aid, exposed as possible no air pressure of the environment U are, by - as shown in Fig. 1 - in the field of The top of the horn-shaped, tubular body is positioned are. In particular, when realizing an acoustic / electrical Directional transducer with help the mentioned at least two spaced microphones will through the envisaged intermediate volume V, in the sense of a "common Mode "suppression, that reaches along the insert 25 differently coupled, same acoustic signals due the compensatory effect of the volume V tends to cancel.

Im weiteren wirkt die Einlage 25 als Verschmutzungsschutz und ist dank ihrer bevorzugt wasserabstossenden Beschichtung leicht reinigbar.In addition, the insert 25 acts as a pollution protection and is light thanks to its preferably water-repellent coating cleanable.

Ein weiterer Vorteil der Einlage 25 mit ihrer Vielzahl von Durchtritten ist - eng gekoppelt an den Aspekt der oben erwähnten "common mode"-Unterdrückung - dass sich eine allfällige Verschmutzung auf beide Mikrophone gleich auswirkt und dadurch keine Verschlechterung der Richtwirkung (Richtcharakteristik) entsteht, was bei konventionellen Richtmikrophonen mit zwei und mehr diskreten Öffnungen ein zentrales Problem darstellt.Another advantage of the insert 25 with its variety of Passed is - closely linked to the aspect of the above "common mode" suppression - that is a possible Pollution on both microphones alike and thereby no deterioration of directivity (directivity) arises, what with conventional directional microphones with two and more discrete openings represents a key problem.

Bezüglich dieser Einlage 25 und ihrer Wirkungen wird auch auf die EP-A-0 847 227 derselben Anmelderin verwiesen.Regarding this insert 25 and its effects will also on EP-A-0 847 227 assigned to the same Applicant.

Anschliessend an die elektro/akustische Wandleranordnung 15 folgt im Grundgehäuse 3 eine Elektronikeinheit 27, dann ein Batteriefach 29. Auf der Aussenseite des Gerätegrundgehäuses, im Bereich zwischen Batteriefach 29 und Elektronikeinheit 27, ist ein Betätigungsschalter 31 vorgesehen. In der perspektivischen Darstellung von Fig. 2 sind insbesondere Anschlussstutzen 5, Grundgehäuse 3, Deckel 19 mit Schalleintrittsschlitz 23 und Einlage 25, weiter der Betätigungsschalter 31 klar ersichtlich.Following to the electro / acoustic transducer assembly 15th follows in the main body 3 an electronic unit 27, then a Battery compartment 29. On the outside of the device base housing, in the area between battery compartment 29 and electronics unit 27, an operating switch 31 is provided. In the perspective Representation of Fig. 2 are in particular connecting piece 5, basic housing 3, cover 19 with sound inlet slot 23 and Insert 25, further the operation switch 31 clearly visible.

Batteriefachbattery

In das in das Grundgehäuse 3 endständig eingelegte Batteriefach 29 wird eine zylinderförmige Flachbatterie bzw. ein entsprechend geformter Akku 33 eingelegt, derart, dass die Achse des Batterie-Zylinders, mit seinen Stirnflächen 33u und 33o, mindestens im wesentlichen, koaxial zur Längsachse A des Grundkörpers liegt.In the battery compartment 29 inserted in the base housing 3, a cylindrical flat battery or a suitably shaped battery 33 is inserted, such that the axis of the battery cylinder, with its end faces 33 u and 33 o , at least substantially, coaxial with the longitudinal axis A. of the main body lies.

An der Basis 30 des Batteriefaches 29, zentriert in der Achse A, ist ein erster federnder Kontakt 35 vorgesehen, ein zweiter 37 tritt federnd mit der Seitenfläche der Batterie 33 in Kontakt. Das Batteriefach 29 ist mit einem in geschlossener Position zur Achse A querstehenden Deckel 39 verschliessbar, welcher am Grundgehäuse 3, bei 41, schwenk- oder bajonettgelagert ist oder am Batteriefach 29.At the base 30 of the battery compartment 29, centered in the axis A, a first resilient contact 35 is provided, a second 37 resiliently contacts the side surface of the battery 33. The battery compartment 29 is in a closed position with one to the axis A querstehenden cover 39 closable, which at the base housing 3, at 41, swivel or bayonet bearings or on the battery compartment 29.

Dieses querliegende Anordnen der Batterie 33 am Hörgerät weist wesentliche Vorteile auf: Die durch den Deckel 39 verschlossene Fläche ist relativ gross, was - wie noch auszuführen sein wird - weiter genutzt werden kann. Weil weiter der Batteriefach-Deckel 39 am tiefsten Ort des Gerätes angeordnet ist und die Deckelstossstellen zum Grundgehäuse 3 quer zur Achse A liegen, ist ein Eindringen von Schweiss in das Batteriefach kaum kritisch. Im weiteren sind bei dieser Batteriefach-Ausbildung die Kontakte 37 und 35 innerhalb des Faches geschützt, der Deckel 39 trägt keine elektrischen Kontakte. Weil weiter der im wesentlichen zylindrische Innenraum des Grundkörpers 3 ausgenützt wird, ergibt sich praktisch kein nicht genutzter, verlorener Raum.This transverse positioning of the battery 33 on the hearing aid has significant advantages: The closed by the lid 39 Area is relatively large, which - as will be explained later - can be used further. Because the battery compartment cover continues 39 is located at the lowest point of the device and the Deckelstossstellen to the base housing 3 are transverse to the axis A, is a penetration of sweat into the battery compartment hardly critical. Furthermore, in this battery compartment training the Contacts 37 and 35 protected inside the compartment, the lid 39 carries no electrical contacts. Because the further essentially cylindrical interior of the body 3 exploited is virtually no unused, lost Room.

In Fig. 3 ist, perspektivisch, eine bevorzugte Ausführungsform des Batteriefach-Deckels 39 dargestellt, als Klappdeckel ausgebildet. Mit dem Schnappscharnierteil 43 ist er einfach vom Schwenklager 41 gemäss Fig. 1 ausklinkbar bzw. daran einrastbar. In einer bevorzugten Ausführungsform weist er im weiteren ein Verriegelungsschloss 45 auf, nebst einer federnden Rastklinke 46.In Fig. 3, in perspective, a preferred embodiment shown the battery cover 39, designed as a hinged lid. With the Schnappscharnieril 43 he is simply from Swivel bearing 41 as shown in FIG. 1 can be unlatched or latched thereto. In a preferred embodiment, it has in the following a locking lock 45, together with a resilient latch 46th

In Fig. 4 ist der Deckel 39 gemäss Fig. 1 in Aussenansicht dargestellt. Das Verriegelungsschloss 45 ist von aussen nur mit einem Werkzeug, beispielsweise einem Schraubenzieher, bedienbar und weist hierzu, auf einer Drehplatine 47, einen Eingriffsschlitz 49 auf. Die Platine 47, welche erst bei Montage des Verriegelungsschlosses 45 am Klappdeckel 39 eingebaut wird, ist spezifisch eingefärbt, in zwei Ausführungen, z.B. rot und blau, womit dieser Teil gleichzeitig als Anzeige dafür dient, ob das jeweils vorliegende Hörgerät ein Gerät für linkes oder rechtes Ohr ist.In Fig. 4, the lid 39 is shown in FIG. 1 in an external view. The locking lock 45 is from the outside only with a tool, such as a screwdriver, operable and has for this purpose, on a turntable 47, an engagement slot 49 on. The board 47, which only when mounting the Locking lock 45 is installed on the hinged lid 39 is specifically colored, in two versions, e.g. Red and blue, with which this part serves as an indication of whether the each hearing device present a device for left or right Ear is.

Wie erwähnt wurde, hat die dargestellte Ausführungsform des Batteriefachs 29, insbesondere die Tatsache, dass der Batterie-Flachzylinder koaxial zur Achse A des Hörgerätes liegt, einen weiteren, wesentlichen Vorteil. Das in Fig. 1 dargestellte Hörgerät entspricht nämlich einer Grundkonfiguration.As has been mentioned, the illustrated embodiment of the Battery compartment 29, in particular the fact that the battery flat cylinder coaxial with the axis A of the hearing aid, a another, significant advantage. The hearing aid shown in Fig. 1 namely corresponds to a basic configuration.

Es ist oft erwünscht, diese Grundkonfiguration mit Zusatzoptionen auszurüsten, beispielsweise mit einer Schnittstelleneinheit für drahtlose Signalübertragung, einer Programmiersteckereinheit, einem weiteren Audioeingang, einem grösseren Akkumulatorfach, einer mechanischen Betätigungseinheit etc. Hierzu wird das in Fig. 1 dargestellte Batteriefach, wie in Fig. 5 dargestellt, umfunktioniert. Die Batterie 33 wird dem Fach entnommen und an deren statt wird der Steckteil 34 eines entsprechenden Zusatzmoduls 51 eingesteckt, elektrisch an den den Batteriekontakten entsprechenden Kontaktstellen 35a bzw. 37a kontaktiert.It is often desirable to have this basic configuration with additional options equip, for example with an interface unit for wireless signal transmission, a programming connector unit, another audio input, a larger rechargeable battery compartment, a mechanical actuator unit, etc. For this purpose the battery compartment shown in Fig. 1, as shown in Fig. 5, converted. The battery 33 is removed from the compartment and at the place instead of the male part 34 of a corresponding Plug-in module 51 inserted, electrically to the battery contacts corresponding contact points 35a and 37a contacted.

Im Hinblick auf den Einsatz solcher Zusatzmodule ist es durchaus möglich, im Fach 29 weitere Kontakte vorzusehen. With regard to the use of such additional modules, it is quite possible to provide 29 further contacts in compartment.

Das nun als eigentliches Batteriefach wirkende Fach 29a mit Batterie 33 ist nun am Zusatzmodul 51 vorgesehen und, entsprechend, der Deckel 39, der z.B. vom Grundgehäuse 3 entfernt und am Zusatzmodul eingeklinkt oder bajonettartig eingerastet wird. Gegebenenfalls können mehrere derartige Module 51 am in Fig. 1 dargestellten Grundmodul des Hörgerätes gestapelt werden. Die jeweilige Fixation der Zusatzmodule 51 erfolgt vorzugsweise mit einer an den Modulen 51 vorgesehenen Einrastpartie 43a, analog zum Scharnierteil 43 am Klappdeckel 39, sowie einem analog zum Schnappteil 46 an besagtem Klappdeckel 39 ausgebildeten Schnappteil 46a oder, bei Bajonettverriegelung, durch entsprechendes Einschieben und Drehverriegeln.The now acting as the actual battery compartment 29a with Battery 33 is now provided on the additional module 51 and, accordingly, the lid 39, e.g. removed from the base housing 3 and is latched on the additional module or engaged in a bayonet-like manner. Optionally, a plurality of such modules 51 am in in Fig. 1st illustrated basic module of the hearing aid are stacked. The respective fixation of the additional modules 51 is preferably carried out with one provided on the modules 51 Einrastpartie 43a, analog to the hinge part 43 on the hinged lid 39, and an analogous to Snap member 46 formed on said hinged lid 39 Snap piece 46a or, with bayonet lock, by appropriate Insert and turn lock.

Damit ist es möglich, das Hörgerät auf höchst einfache Art und Weise modular den Wünschen entsprechend auszubauen, Batterie bzw. Akkumulator 33 bleiben immer ohne weiteres von aussen zugänglich.This makes it possible, the hearing aid in the simplest way and Modular way of expanding according to the wishes, battery or accumulator 33 always remain readily accessible from the outside.

Elektrisch/akustische WandleranordnungElectric / acoustic transducer arrangement

In Fig. 6 ist, vereinfacht, der Aufbau und die Lagerung der erwähnten Anordnung 15 am Grundgehäuse 3 und in Ansicht gemäss Fig. 1 dargestellt. Die Anordnung 15 umfasst, in einem Lautsprechergehäuse 53 gekapselt, die Lautsprecheranordnung (nicht dargestellt) mit einer Lautsprechermembran. Durch schematisch bei 55 eingezeichnete Kopplungsöffnungen werden die durch die Lautsprechermembran angeregten Schallwellen vom membranrückseitigen Raum im Lautsprechergehäuse 53 in den Umgebungsraum U53, des Lautsprechergehäuses 53 gekoppelt. Vom Membran-vorderseitigen Raum werden die akustischen Signale - wie mit dem Pfeil S dargestellt - zu dem in Fig. 1 ersichtlichen Übertragungskanal 11 gekoppelt. In Fig. 6 is simplified, the structure and the storage of said assembly 15 on the base housing 3 and in view of FIG. 1 is shown. The assembly 15 includes, encapsulated in a speaker housing 53, the speaker assembly (not shown) with a speaker diaphragm. By schematically drawn at 55 coupling openings, the sound waves excited by the speaker membrane from the membrane-back space in the speaker housing 53 in the surrounding space U 53 , the speaker housing 53 are coupled. From the membrane front space, the acoustic signals are - as shown by the arrow S - coupled to the apparent in Fig. 1 transmission channel 11.

Das Lautsprechergehäuse 53 ist allseits in federnden, vorzugsweise in gummielastischen Lagerungen 57, im wesentlichen frei schwingend gehaltert. Durch die Lagerungen 57 wird zwischen Lautsprechergehäuse-Aussenwand und einer Kapselung 59 der relativ grosse Raum U53 definiert, welcher zu einer namhaften Anhebung der Tieftöne führt. Der membranrückseitige Resonanzraum wird durch den Raum U53 um ein Vielfaches vergrössert. Damit der Raum U53 akustisch vollumfänglich wirksam ist, sind die Kapselung 59 und ihre Halterung 61 dicht verbunden.The speaker housing 53 is supported on all sides in resilient, preferably in rubber-elastic bearings 57, substantially free swinging. Due to the bearings 57, the relatively large space U 53 is defined between loudspeaker housing outer wall and an encapsulation 59, which leads to a considerable increase in the bass tones. The membrane-rear resonance space is increased by the space U 53 many times. So that the space U 53 is acoustically fully effective, the enclosure 59 and its holder 61 are tightly connected.

Damit wird das Lagerungsvolumen für die Lautsprecheranordnung akustisch optimal genutzt. Die Kapselung 59 wirkt weiter bevorzugterweise als magnetisches Schirmungsgehäuse und ist hierzu bevorzugt aus µ-Metall gefertigt. Sie ist becherförmig ausgebildet und ist an der Halterung 61, als Kunststoffträgerteil ausgebildet, dichtend eingehakt. Zwischen Kapselung 59, Halterung 61 einerseits und Lautsprechergehäuse 53 sind die erwähnten federnden, vorzugsweise gummielastischen, Lagerungen 57 gespannt.This will be the storage volume for the speaker assembly acoustically optimally used. The encapsulation 59 more preferably acts as a magnetic shielding housing and is this preferably made of μ-metal. It is cup-shaped and is on the holder 61, as a plastic carrier part trained, tightly hooked. Between encapsulation 59, holder 61 on the one hand and speaker housing 53 are mentioned resilient, preferably rubber-elastic, bearings 57 stretched.

In Fig. 8 ist rein prinzipiell die erläuterte akustische Kopplung dargestellt. Die Membran 54 des Lautsprechers im Gehäuse 53 definiert im besagten Gehäuse einen ersten Raum R1, welcher mit dem akustischen Ausgang des Hörgerätes - wie mit S dargestellt - gekoppelt ist sowie einen zweiten R2, der über eine oder mehrere Öffnungen 55 mit dem zwischen Kapselung 59 und Gehäuse 53 gebildeten Raum U53 gekoppelt ist.In Fig. 8, the illustrated acoustic coupling is shown in principle purely. The diaphragm 54 of the loudspeaker in the housing 53 defines in said housing a first space R 1 which is coupled to the acoustic output of the hearing aid as shown at S and a second R 2 connected via one or more openings 55 to the one between encapsulation 59 and housing 53 formed space U 53 is coupled.

Betätigungsschalter 31Actuator switch 31

In Fig. 7 ist eine bevorzugte Ausführungsform des Betätigungsschalters 31, vereinfacht und schematisiert, dargestellt. Der Betätigungsschalter 31 umfasst einen Kipptaster 63, der einseitig, bei 65, kippgelagert ist.In Fig. 7 is a preferred embodiment of the actuating switch 31, simplified and schematic, shown. Of the Actuator switch 31 comprises a toggle button 63, the one-sided, at 65, tilted.

Das Kipplager 65 ist an einem Schlitten 67 angeformt, welcher - wie mit dem Doppelpfeil F dargestellt - bezüglich des Grundgehäuses 3 linear verschieblich gelagert ist. Wie schematisch mit dem Federkontakt 69, bezüglich des Grundgehäuses 3 fix, und dem Überbrückungskontakt 70 am Schlitten 67 dargestellt, wird durch hin und her Schieben des Schlittens über Taster 63 das Gerät ein- und ausgeschaltet.The tilting bearing 65 is formed on a carriage 67, which - as shown by the double arrow F - with respect to the basic housing 3 is mounted linearly displaceable. As schematically with the spring contact 69, with respect to the basic housing 3 fix, and the Bridging contact 70 shown on the carriage 67 is through back and forth sliding the carriage via button 63 the device switched on and off.

Im Schlitten 67 ist eine durchgehende Nut 72 eingearbeitet, durch welche eine Gehäuse-3-feste Kontaktpille 73 durchragt. Diese ist überdeckt durch eine am Schlitten 67 angeordnete federnde Kontaktpartie 75, welche bevorzugterweise als Tastaturelement aus gummielastischem, mindestens teilweise elektrisch leitendem Kunststoff gefertigt ist, wie bekannt beispielsweise von Fernbedienungstastaturen. Bei kippender Betätigung des Kipptasters 63 - wie mit dem Doppelpfeil K dargestellt - tritt die Kontaktpartie 75 mit der Kontaktpille 73 in Kontakt und erstellt zwischen diesen Elementen eine elektrische Verbindung. Obwohl sich für den Fachmann eine Vielzahl möglicher elektrischer Verbindungen unter Einschluss der Schaltstrecke S1, betätigt durch die Schlittenbewegung F, und der Schaltstrecke S2, betätigt durch die Kippbewegung K des Kipptasters 63, ergibt, ist bevorzugterweise - wie in Fig. 7 gestrichelt dargestellt - der Federkontakt 69 mit der Gerätebatterie 33 verbunden, der Überbrückungskontakt 70 mit der Kontaktpartie 75, und es wirkt damit die Kontaktpille 73 als elektrischer Ausgang der Schaltanordnung. In the carriage 67, a continuous groove 72 is incorporated, through which a housing-3 fixed contact pill 73 protrudes. This is covered by an arranged on the carriage 67 resilient contact portion 75, which is preferably made as a keyboard element made of rubber-elastic, at least partially electrically conductive plastic, as known, for example, remote control keyboards. When tilting operation of the toggle button 63 - as shown by the double arrow K - the contact part 75 comes into contact with the contact pill 73 and creates an electrical connection between these elements. Although a variety of possible electrical connections, including the switching path S 1 , actuated by the carriage movement F, and the switching path S 2 , actuated by the tilting movement K of the toggle button 63, results for the person skilled in the art, it is preferable - as shown in dashed lines in FIG - The spring contact 69 connected to the device battery 33, the bridging contact 70 with the contact portion 75, and it acts so that the contact pill 73 as the electrical output of the switching device.

Damit wirkt der Betätigungsschalter 31 sowohl als Ein-/Aus-Schiebeschalter und zusätzlich, in Ein-Position, als Toggelschalter, womit - beispielsweise zur raschen individuellen Verstärkungseinstellung - in Schritten auf die Elektronikeinheit 27 gemäss Fig. 1 eingewirkt wird.Thus, the operation switch 31 acts both as an on / off slide switch and additionally, in the on position, as a toggle switch, with which - for example, for rapid individual gain adjustment - in steps on the electronics unit 27 as shown in FIG. 1 is acted upon.

Mit dem Betätigungsschalter 31 werden mithin zwei Funktionen kombiniert, Schiebeschalter und Toggelschalter, eine Funktionsverschmelzung, die insbesondere für das erfindungsgemässe Hinterohrgerät höchst vorteilhaft ist. Die Bedienungsunterschiedlichkeit sichert, dass keine Funktionsverwechslung stattfindet, was bei Vorsehen zweier Schalter für die erwähnten beiden Funktionen wesentlich kritischer ist.With the operation switch 31 thus two functions combined, slide switch and toggle switch, a functional fusion, in particular for the inventive rear ear device is highly advantageous. The operation difference ensures that no functional confusion takes place, which in providing two switches for the mentioned two functions much more critical.

Aufbau des Gehäuses 3Structure of the housing 3

Wie sich insbesondere aus Fig. 5 ergibt, ist das Grundgehäuse 3 durch ein gebogenes, entsprechend geformtes Rohrteil gebildet. In einer bevorzugten Ausführungsform wird dieses Teil 3 einteilig ausgebildet, bevorzugt aus Kunststoff und ist nicht, wie sonst beim Aufbau derartiger Hörgeräte üblich, entlang von in Fig. 5 mit M eingetragenen Mantellinien, in zwei Schalen trennbar. Damit ist auch die Assemblierung der einzelnen Einheiten in das Grundgehäuse 3 gegeben: Sie werden einfach ins Rohr eingeführt, was wesentlich einfacher ist als eine Assemblierung an geöffneten Schalen. Ein weiterer Vorteil einer rohrförmigen, einteiligen Ausführungsform ist ihre viel grössere Stabilität gegenüber einem geteilten Gehäuse. Dadurch ist eine Reduktion der Gehäusewandstärke und dadurch eine Verkleinerung desselben möglich, bzw. bei gegebenem Aussenvolumen eine Erhöhung des nutzbaren Innenvolumens. As can be seen in particular from FIG. 5, the basic housing 3 formed by a bent, correspondingly shaped pipe part. In a preferred embodiment, this part 3 is made in one piece formed, preferably made of plastic and is not like otherwise common in the construction of such hearing aids, along in Fig. 5 with M registered generatrices, separable in two shells. This also includes the assembly of the individual units into the basic housing 3: they are simply inserted into the tube, which is much easier than an assembly opened cups. Another advantage of a tubular, one-piece embodiment is their much greater stability opposite a split housing. This is a reduction the housing wall thickness and thereby a reduction of the same possible, or for a given external volume an increase in the usable interior volume.

Vorteile der GesamtkonfigurationAdvantages of the overall configuration

Mit Blick auf Fig. 1 ist ersichtlich, insbesondere auch bei der bevorzugten einteiligen Ausbildung des Grundgehäuses 3, dass die einzelnen Baueinheiten, insbesondere 11, 15, 27, 29 und/oder 51, durch axiales, sequentielles Einschieben in das Grundgehäuse 3 assembliert werden. Formgebung des Gehäuses 3 mit entsprechenden Führungen sichert dabei eine rasche, exakte Positionierung, wobei die gegenseitige elektrische Kontaktierung zwischen den elektrisch betriebenen Einheiten lötfrei, mittels federnder Kontaktierungen erfolgt. Damit können die vorzusehenden Einheiten vorab ausgetestet und ausgemessen und ohne eine Beeinträchtigung befürchten zu müssen darnach assembliert werden. Diese Assemblierung kann ohne weiteres automatisiert werden. Das Gesamtgehäuse mit Grundgehäuse 3 und Deckel 19, gegebenenfalls 39, ist, an den Stossstellen mit entsprechenden Dichtungen versehen, einfach dichtbar.With reference to Fig. 1 it can be seen, especially in the preferred one-piece design of the base housing 3, that the individual units, in particular 11, 15, 27, 29 and / or 51, by axial, sequential insertion into the Base housing 3 are assembled. Shape of the housing 3 with appropriate guides ensures a quick, accurate Positioning, whereby the mutual electrical contact solderless between the electrically operated units, done by means of resilient contacts. So that can beforehand tested and measured and measured without fear of being impaired, it has been assembled become. This assembly can be easily automated become. The overall housing with basic housing 3 and cover 19, optionally 39, is at the joints with corresponding Provided seals, easy sealable.

Die bevorzugte Ausführung der elektrisch/akustischen Wandleranordnung 15 sichert eine optimale magnetische Abschirmung der Lautsprecher und eine optimale akustische Abdichtung bezüglich Körperschall.The preferred embodiment of the electrical / acoustic transducer assembly 15 ensures optimum magnetic shielding of the Speakers and an optimal acoustic seal regarding Structure-borne sound.
