Abstract

A hearing aid of the type which is worn behind the ear has a battery compartment and a volume control knob at its lower end. The compartment and knob are at right angles to the longitudinal axis of the device.

Description

Die Erfindung betrifft hinter dem Ohr zu tragende Hörgeräte nach dem Oberbegriff des Anspruchs 1.The invention relates to hearing aids to be worn behind the ear according to the preamble of claim 1.

Da das Gehäuse bei diesen Geräten durch die vorgesehene Tragweise hinter dem Ohr an die Form und Größe gebunden ist, die der dort vorhandene Raum zur Verfügung stellt, kommt es bei der Konstruktion eines derartigen Gerätes sehr auf eine raumsparende Anordnung der Bauelemente an. Außerdem sollen die zur Kontrolle des Betriebes des Gerätes vorgesehenen Steller gut bedienbar sein.Since the housing in these devices is tied behind the ear to the shape and size provided by the space available there, the construction of such a device is very important for a space-saving arrangement of the components. In addition, the controls provided to control the operation of the device should be easy to use.

Die Erfindung geht dabei davon aus, die viel Raum beanspruchenden Teile an die Enden des Gehäuses und die Teile, die gut verteilt werden können, dazwischen anzuordnen. So kann eine sehr gute Anpassung der Form des Gerätes an den hinter dem Ohr vorhandenen Raum erreicht werden.The invention is based on the arrangement of the parts that take up a lot of space at the ends of the housing and the parts that can be well distributed between them. This allows a very good adaptation of the shape of the device to the space behind the ear.

Darüber hinaus hat sich die Erfindung die Aufgabe gestellt, insbesondere den Lautstärkeregler hinsichtlich seiner Einstellbarkeit so anzuordnen, daß seine Einstellung stets kontrollierbar ist. Dies wird gemäß den Maßnahmen des Kennzeichens des Anspruchs 1 erreicht.In addition, the invention has set itself the task, in particular to arrange the volume control in terms of its adjustability so that its setting is always controllable. This is achieved in accordance with the measures of the characterizing part of claim 1.

Durch die Drehung des am unteren Ende des Gehäuses angeordneten Lautstärkestellers um einen Winkel von 90° um eine Achse, die in Richtung der Längsausdehnung des Gehäuses liegt, wird erreicht, daß der gesamte Drehsteller an die Oberfläche des Gehäuses gebracht wird. So ist er gut greifbar und kann auf einfache Weise eingestellt werden. Außerdem kann dieser Steller an seiner glatten Oberfläche mit einer tastbaren Markierung versehen werden, deren Stellung durch Anfassen des Stellers feststellbar ist. Als günstig hat es sich erwiesen, zur Lautstärkeregelung eine Verdrehung des Stellers um 270° oder, bezogen auf eine Uhr, von 000 bis 900 Uhr festzulegen.By rotating the volume control arranged at the lower end of the housing by an angle of 90 ° about an axis lying in the direction of the longitudinal extent of the housing, it is achieved that the entire rotation is brought to the surface of the housing. This makes it easy to grasp and easy to set. In addition, this actuator can be provided with a tactile marking on its smooth surface, the position of which can be determined by touching the actuator. It has proven to be advantageous to set the volume control a rotation of the actuator by 270 ° or, based on a clock, from 0 00-9 00.

Als zweckmäßig hat es sich dabei herausgestellt, das Gehäuse aus zwei Schalen herzustellen, die in einer Trennlinie aneinandergrenzen, die entlang der seitlichen Wände verläuft, so daß eine Schale am Innenbogen und eine Schale am Außenbogen des Gehäuses liegt. Dabei können die beiden Schalen unterschiedlich gefärbt sein und einen günstigen Effekt erzeugen, der das Gerät zierlicher erscheinen läßt, was insbesondere hinsichtlich des Wunsches Schwerhöriger wichtig ist, das Gerät möglichst unsichtbar tragen zu können.It has proven to be expedient to produce the housing from two shells which adjoin one another in a dividing line which runs along the side walls, so that one shell lies on the inner arch and one shell on the outer arch of the housing. The two shells can be colored differently and produce a favorable effect that makes the device appear more delicate, which is particularly important with regard to the desire of the hearing impaired to be able to wear the device as invisibly as possible.

Um Schalen unterschiedlicher Farbe dem jeweiligen Bedarf anpassen zu können, ist es weiterhin zweckmäßig, die Farbe insbesondere derjenigen Schale, die am äusseren Bogen liegt, ändern zu können, etwa durch Austausch der gerade angebrachten Schale gegen diejenige, welche die gewünschte Farbe hat. Dazu ist besonders eine Verbindung der beiden Schalen durch Steck- und Schraubverbindungen geeignet.In order to be able to adapt bowls of different colors to the respective requirements, it is also expedient to be able to change the color, in particular of the bowl that lies on the outer arch, for example by exchanging the bowl that has just been fitted for the bowl that has the desired color. A connection of the two shells by plug and screw connections is particularly suitable for this.

Am oberen Ende, d.h. an dem Ende des Gehäuses, an dem es am Ohr angehängt wird, werden die Schallwandler untergebracht, um einerseits den Schall ohne große Verluste mit dem Mikrofon frontal aufnehmen zu können und andererseits den Schall aus dem Hörer auf kürzestem Wege dem Ohrkanal zuleiten zu können. Dabei sind die beiden Wandler in Räume in üblicher Weise eingebaut, die durch eine Zwischenplatte voneinander getrennt sind. Diese Platte kann außerdem noch als Basis für die Halterung eines Schalters benutzt sein, mit welchem das Gerät aus- und eingeschaltet wird und mit dem die Aufnahme von Signalen vom Mikrofon auf eine Hörspule umgeschaltet werden kann.At the upper end, ie at the end of the housing to which it is attached to the ear, the sound transducers are housed in order to be able to pick up the sound with the microphone without great losses on the one hand and on the other hand to keep the sound from the listener as short as possible To be able to direct the ear canal. The two transducers are installed in rooms in the usual way, which are separated from each other by an intermediate plate. This plate can also be used as the basis for holding a switch with which the device is switched on and off and with which the recording of signals from the microphone can be switched to an audio coil.

Der zwischen den Wandlern und der Batterie mit dem Lautstärkesteller liegende Raum ist wie bei bekannten Geräten zur Unterbringung des Verstärkers benutzbar. Ein solcher Verstärker kann in einem Mehrschichten(Multilayer)-System aufgebaut sein. Um auf dem kleinen Raum möglichst viele Bauelemente unterbringen zu können, hat es sich als zweckmäßig erwiesen, ein Dreischichtensystem zu verwenden, das,mit mehreren Biegezonen versehen, dem vorhandenen Raum besonders gut angepaßt werden kann.The space between the transducers and the battery with the volume control can be used as in known devices for accommodating the amplifier. Such an amplifier can be constructed in a multilayer system. In order to be able to accommodate as many components as possible in the small space, it has proven expedient to use a three-layer system which, provided with several bending zones, can be adapted particularly well to the existing space.

Der Verstärker kann auch Elemente umfassen, die zur Einstellung der Frequenzübertragungskurve und der Steuerung der Dynamik (peac clipping = PC) dienen. Es ist günstig, sie dabei so anzubringen, daß sie am äußeren Bogen liegen und durch eine etwa mit einer Klappe verschließbare Öffnung der Schale des Gehäuses zugänglich sind. Die Steller können mit einer Hörspule zu einer Baueinheit zusammengefaßt sein, die in den Aufbau des Verstärkers einbezogen werden kann.The amplifier can also include elements that are used to set the frequency transmission curve and to control the dynamics (peac clipping = PC). It is convenient to attach them so that they are on the outer arch and are accessible through an approximately closable opening of the shell of the housing. The actuators can be combined with a hearing coil to form a structural unit which can be incorporated into the structure of the amplifier.

Am unteren, d.h. dem der Aufhängung gegenüberliegenden Ende des Gehäuses liegt ein von außen zugänglicher Raum, in welchem die Stromquelle etwa hinter einer Klappe untergebracht wird. Parallel dazu kann neben ihr der Lautstärkeregler liegen. Letzterer wird dabei vorzugsweise an der Außenschale befestigt, weil dann der eigentliche mechanische Steller ein Drehrädchen sein kann, das an der Oberfläche der Schale liegt und so voll zugänglich ist. Als tastbare Markierung kann der Steller an seiner äußeren Fläche eine Noppe erhalten, deren Stellung beim Anfassen gefühlt werden kann. Außerdem ist es zweckmäßig, der Noppe eine von der Umgebung unterschiedliche Farbe zu geben, so daß die Stellung des Lautstärkereglers auch einfach gesehen werden kann.At the lower end, ie the end of the housing opposite the suspension, there is an externally accessible space in which the power source is accommodated, for example, behind a flap. At the same time, the volume control can lie next to it. The latter is preferred attached to the outer shell, because then the actual mechanical actuator can be a rotating wheel that lies on the surface of the shell and is thus fully accessible. As a tactile marking, the actuator can have a knob on its outer surface, the position of which can be felt when touched. It is also advisable to give the knob a different color from the surroundings so that the position of the volume control can also be easily seen.

Als Stromquelle zum Betrieb des Gerätes kann eine Batterie oder ein Akkumulator verwendet werden. Dieser wird dann in dem Raum neben dem Lautstärkeregler untergebracht. Der Raum ist etwa mit einer Klappe vom Innenbogen des Gehäuses her verschlossen. Zum Öffnen ist ein Scharnier vorgesehen, das quer zur Längsausdehnung des Gerätes am Ende des Innenbogens des Gehäuses liegt. So kann die Stromquelle einfach und schnell ausgewechselt werden.A battery or an accumulator can be used as the power source for operating the device. This is then placed in the room next to the volume control. The room is closed with a flap from the inside of the case. A hinge is provided for opening, which lies transversely to the longitudinal extent of the device at the end of the inner arc of the housing. The power source can be replaced quickly and easily.

In der Figur 1 ist mit 1 das Gehäuse eines Hinterohrgerätes bezeichnet. Es besteht aus einer gebogenen, nach außen offenen Schale 2 und einer nach innen offenen Schale 3. Beide sind mit ihren offenen Seiten aneinandergelegt und bilden so das Gehäuse 1.In FIG. 1, 1 denotes the housing of a rear ear device. It consists of a curved shell 2 which is open to the outside and a shell 3 which is open to the inside. Both are placed with their open sides against one another and thus form the housing 1.

Am oberen Ende des Gehäuses 1 befindet sich ein Traghaken 4 und am gegenüberliegenden unteren Ende ein Behälter 5 für eine Stromquelle. Dieser Behälter 5 ist mit einem Deckel 6, der nach der Innenseite des gebogenen Gehäuses 1 hin aufklappbar ist, verschlossen. Nach der Außenseite liegt am Behälter 5 ein Lautstärkeregler 7, der an seinem Einstellrädchen 8 erkennbar ist. Der äußere Bogen der Schale 3 weist etwa in seiner Mitte eine Verschlußklappe 9 auf und zwischen dieser und dem oberen Ende einen Schalter 10. Am Ende des von einem Schalleitungskanal 22 (Figur 6) durchsetzten Traghakens 4 ist ein Schlauch 11 angeschlossen, der in eine elastische Ohrolive 12 mündet, die zum Anschluß des Gerätes an den Ohrkanal ihres Benutzers dient.At the upper end of the housing 1 there is a carrying hook 4 and at the opposite lower end there is a container 5 for a power source. This container 5 is closed with a lid 6, which can be opened towards the inside of the curved housing 1. On the outside there is a volume control 7 on the container 5, which can be recognized by its adjusting wheel 8. The outer arch of the shell 3 has a closure flap 9 approximately in its center and a switch 10 between it and the upper end. At the end of the carrying hook 4 penetrated by a shutter line channel 22 (FIG. 6), a hose 11 is connected, which is connected to an elastic Ear olive 12 opens, which is used to connect the device to the ear canal of your user.

Das Gerät wird, wie aus Figur 2 ersichtlich, am Ohr 15 derart getragen, daß es mit seinem Innenbogen an der Rückseite der Ohrwurzel anliegt. Mit dem Haken 4 wird es am oberen Ohransatz festgehalten. Wie aus Figur 3 ersichtlich, kann an der Stirnfläche 16 durch eine Öffnung 17 Schall zu einem Mikrofon 18 gelangen. Dort wird dieser in elektrische Signale umgesetzt, die in einem, im mittleren Teil des Gehäuses 1 liegenden Verstärker 19 in ihrer Intensität gesteigert und schließlich einem Hörer 20 zugeführt werden. Von dort gelangt der aus den verstärkten Signalen erhaltene Schall über eine Leitung 21 in den im Traghaken 4 liegenden Schallleitungskanal 22 (Figur 6). Der Verstärker 19 wird von der im Raum 5 untergebrachten Stromquelle mit Energie versorgt.As can be seen from FIG. 2, the device is worn on the ear 15 in such a way that its inner arch lies against the back of the ear root. With the hook 4 it is held on the upper ear base. As can be seen from FIG. 3, sound can reach a microphone 18 on the end face 16 through an opening 17. There it is converted into electrical signals, which are in a Ver located in the central part of the housing 1 19 increased in intensity and finally fed to a listener 20. From there, the sound obtained from the amplified signals passes via a line 21 into the sound conduction channel 22 located in the support hook 4 (FIG. 6). The amplifier 19 is supplied with energy by the current source housed in the room 5.

Die eigentliche Steuerung der zum Ohr 15 gelangenden Lautstärke erfolgt am Stellerrädchen 8. Die Einstellung dieses Rädchens ist an der Lage einer anders als ihre Umgebung gefärbten Noppe 25 sichtbar und, da diese Noppe 25 über die Oberfläche des Stellerrädchens 8 vorsteht, auch fühlbar.The actual control of the volume reaching the ear 15 takes place on the adjusting wheel 8. The setting of this wheel is visible in the position of a knob 25 colored differently from its surroundings and, since this knob 25 protrudes beyond the surface of the adjusting wheel 8, can also be felt.

Der Verstärker 19 ist an Stellern 26 und 27, die über Einstelldrehelemente 28, 29 in ihrer Wirkung veränderbar sind, auch in seiner Wirksamkeit hinsichtlich der durchgelassenen Frequenz und der Wirkung sehr hoher Schallintensitäten durch eine einstellbare PC beeinflußt.The amplifier 19 is at actuators 26 and 27, whose effect can be changed via adjusting rotary elements 28, 29, also its effectiveness with regard to the transmitted frequency and the effect of very high sound intensities is influenced by an adjustable PC.

Der Schalter 10 befindet sich, wie aus Figur 5 ersichtlich, auf einer Platte 30, wo er in angepaßten Halterungen 31, 32 sowie der Öffnung 33 der Schale 3 befestigt ist. Er dient zum Ausschalten und zum Umschalten der Signalaufnahme mittels Mikrofon 18 oder einer mit den Stellern 26 und 27 zu einer Baueinheit zusammengeschlossenen Induktionsaufnahmespule 34.The switch 10 is, as can be seen from FIG. 5, on a plate 30, where it is fastened in adapted holders 31, 32 and the opening 33 of the shell 3. It is used for switching off and for switching over the signal recording by means of a microphone 18 or an induction recording coil 34 which is connected to the actuators 26 and 27 to form a structural unit.

Die beiden Schalen 2 und 3 sind durch Schrauben 35 bis 38 lösbar miteinander verbunden, so daß die obere Schale 3 ausgewechselt werden kann. Sie kann etwa in unterschiedlichen Farbestellungen gegenüber der unteren Schale 2 gewählt werden.The two shells 2 and 3 are detachably connected to one another by screws 35 to 38, so that the upper shell 3 can be replaced. It can be chosen in different colors compared to the lower shell 2.

Die im Raum 5 untergebrachte Stromquelle kann nach Öffnen des Deckels 6 ausgewechselt werden. Der Dekkel 6 selbst ist mittels eines Schanppansatzes 39 an seinem äußeren Ende an einer Vertiefung 40 (Figur 4) einschnappend gehalten. An seinem gegenüberliegenden Ende ist der Deckel 6 in einem Scharnier 41 schwenkbar am unteren Ende der Schale 2 gelagert.The power source housed in room 5 can be replaced after opening cover 6. The cover 6 itself is snapped onto a recess 40 (FIG. 4) at its outer end by means of a flap attachment 39. At its opposite end, the cover 6 is pivotally mounted in a hinge 41 at the lower end of the shell 2.

Der Traghaken 4 ist an einem außen mit einem Gewinde versehenen Ansatz 42 an der oberen Stirnseite der Schale 2 des Gehäuses 1 angeschraubt. Seine Bohrung, d.h. der Schallkanal 22, ist dazu an seinem gehäuseseitigen Ende mit einem Innengewinde versehen. Zur Aufhebung der durch diese Ausnehmung erhaltenen Schwächung des Traghakens 4 ist an der Außenseite der Verschraubung ein Metallring 43 aufgezogen.The support hook 4 is screwed to an externally threaded shoulder 42 on the upper end face of the shell 2 of the housing 1. Its bore, i.e. For this purpose, the sound channel 22 is provided with an internal thread at its housing end. In order to cancel the weakening of the support hook 4 obtained by this recess, a metal ring 43 is mounted on the outside of the screw connection.
