Abstract
Description
Die vorliegende Erfindung betrifft ein Hinterohr-Hörgerät nach dem Oberbegriff von Anspruch 1.The present invention relates to a behind-the-ear hearing aid according to the preamble of
Bei derartigen Hörgeräten ist es üblich, einen Ein-/AusSchalter vorzusehen und, davon getrennt, ein weiteres Betätigungsorgan, beispielsweise zur Einstellung der Verstärkung. Dies führt insbesondere bei Bedienung des applizierten Hörgerätes zu mühsamem Ertasten des jeweils benötigten Betätigungsorgans, ganz abgesehen davon, dass für die vorgesehenen Betätigungsorgane namhaft Bauvolumina verbraucht werden und das Vorsehen der erwähnten Organe zu einer namhaften Komplizierung des Hörgerätes mit den vorzusehenden elektrischen Verbindungen führt, somit auch zu einer erhöhten Störanfälligkeit.In such hearing aids, it is customary to provide an on / off switch and, separately, another actuator, for example, to adjust the gain. This leads in particular when operating the applied hearing aid to cumbersome palpation of the respective required actuator, quite apart from the fact that for the intended actuators namig construction volumes are consumed and the provision of the mentioned organs leads to a considerable complication of the hearing with the electrical connections to be provided, thus also to an increased susceptibility to interference.
Derartige Hörgeräte sind im Stand der Technik bekannt, beispielsweise aus den Dokumenten
Die vorliegende Erfindung bezweckt, die erwähnten Nachteile zu beheben. Zu diesen Zweck zeichnet sich das erfindungsgemässe Hörgerät nach dem Kennzeichen von Anspruch 1 aus.The present invention aims to remedy the disadvantages mentioned. For this purpose, the hearing aid according to the invention is characterized according to the characterizing part of
Mithin werden erfindungsgemäss an ein und demselben Betätigungsorgan zwei Kategorien von Schaltfunktionen kombiniert, nämlich, in den erwähnten Positionen, bevorzugt EIN-/AUSSchaltung des Hörgerätes und in zweiter Betätigungsrichtung beispielsweise Verstellung der Verstärkung. Damit wird einerseits die Bedienungsfreundlichkeit namhaft erhöht, es ist ohne weiteres möglich, am einen vorgesehenen Betätigungsschalter die beiden unterschiedlichen Betätigungsarten fühlend zu unterscheiden. Weiter benötigt ein einziger erfindungsgemäss vorgesehener Betätigungsschalter baulich weniger Volumen, und zudem wird das Hörgerät als Ganzes einfacher, indem elektrische Verbindungen zu Schaltorganen nur in den Bereich des erfindungsge-mäss vorgesehenen einen Betätigungsorgans geführt werden müssen.Thus, according to the invention, two categories of switching functions are combined on one and the same actuating member, namely, in the mentioned positions, preferably ON / OFF switching of the hearing aid and in the second actuating direction, for example adjustment of the amplification. Thus, on the one hand, the ease of use is notably increased, it is readily possible to distinguish the two different types of actuation on a designated operating switch. Furthermore, a single operating switch provided according to the invention requires less volume and, moreover, the hearing aid as a whole becomes simpler by virtue of electrical connections to switching devices only within the scope of the invention provided an actuator must be performed.
Durch Vorsehen lediglich eines mechanischen betätigbaren Organs wird auch die Störanfälligkeit reduziert und, insbesondere bei Auftreten von Störungen, die Revision wesentlich einfacher.By providing only a mechanically operable member and the susceptibility is reduced and, especially in the presence of interference, the revision much easier.
Wie erwähnt, wird in einer bevorzugten Ausführungsform die eine der Positionen als Einschaltposition des Hörgerätes, die andere als Ausschaltposition eingesetzt, und es wirkt das Betätigungsorgan bei Betätigung in zweiter Richtung als Toggelschalter. In einer weiteren bevorzugten Realisationsform ist das Betätigungsorgan an einem im wesentlichen linear verschieblichen Schieber kippgelagert und weist einen, durch Betätigung in zweiter Richtung, mit einem gerätefesten Schaltkontakt in Kontakt bringbaren Kontakt auf. Dieser Kontakt ist dabei bevorzugterweise aus gummielastischem Kunststoff gefertigt, vorzugsweise hütchenförmig, wie dies von Computertastaturmatten oder Fernbedienungstastaturen bekannt ist. Weiter bevorzugt liegt die erste Betätigungsrichtung des Bedienungsorgans im wesentlichen in Richtung von Mantellinien des Gerätekörpers, vorzugsweise entlang Krümmungs-aussenseitigen Mantellinien, bezogen auf die Gerätekörperbiegung, und es ist die zweite Betätigungsrichtung senkrecht zur Gerätekörperwandung.As mentioned, in one preferred embodiment, one of the positions is used as a switch-on position of the hearing aid, the other as a switch-off position, and the actuator acts as a toggle switch when actuated in the second direction. In a further preferred embodiment, the actuating member is tilt-mounted on a slide which is displaceable in a substantially linear manner and has a contact which can be brought into contact with a device-fixed switch contact by actuation in the second direction. This contact is preferably made of rubber-elastic plastic, preferably hat-shaped, as is known from computer keyboard mats or remote keyboards. More preferably, the first operating direction of the operating member is located substantially in the direction of generatrices of the device body, preferably along curvature-outer side generatrices, based on the device body deflection, and it is the second direction of actuation perpendicular to the device body wall.

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
Wie aus
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
Im weiteren wirkt die Einlage 25 als Verschmutzungsschutz und ist dank ihrer bevorzugt wasserabstossenden Beschichtung leicht reinigbar.In addition, the
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

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
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
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 arrangement of the

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
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.Thus, the storage volume for the speaker assembly is used optimally acoustically.

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
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
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.Thus, two functions are combined with the
