Description

Die Erfindung betrifft ein Tief-Ohrkanal-Hörinstrument, insbesondere ein Hörgerät, zum Tragen tief im Ohrkanal eines Benutzers.The invention relates to a deep-ear canal hearing instrument, in particular a hearing aid, for carrying deep in the ear canal of a user.

Hörinstrumente können als Hörgeräte ausgeführt sein. Ein Hörgerät dient der Versorgung einer hörgeschädigten Person mit akustischen Umgebungssignalen, die zur Kompensation bzw. Therapie der jeweiligen Hörschädigung verarbeitet und verstärkt sind. Es besteht prinzipiell aus einem oder mehreren Eingangswandlern, aus einer Signalverarbeitungseinrichtung, einer Verstärkungseinrichtung, und aus einem Ausgangswandler. Der Eingangswandler ist in der Regel ein Schallempfänger, z.B. ein Mikrofon, und/oder ein elektromagnetischer Empfänger, z.B. eine Induktionsspule. Der Ausgangssignalerzeuger ist in der Regel als elektroakustischer Wandler, z. B. Miniaturlautsprecher, oder als elektromechanischer Wandler, z. B. Knochenleitungshörer, realisiert. Er wird auch als Hörer oder Receiver bezeichnet. Der Ausgangssignalerzeuger erzeugt Ausgangssignale, die zum Gehör des Patienten geleitet werden und beim Patienten eine Hörwahrnehmung erzeugen sollen. Der Verstärker ist in der Regel in die Signalverarbeitungseinrichtung integriert. Die Stromversorgung des Hörgeräts erfolgt durch eine ins Hörgerätegehäuse integrierte Batterie. Die wesentlichen Komponenten eines Hörgeräts sind in der Regel auf einer gedruckten Leiterplatine als Schaltungsträger angeordnet bzw. damit verbunden.Hearing instruments can be designed as hearing aids. A hearing aid is used to supply a hearing-impaired person with acoustic ambient signals that are processed and amplified for compensation or therapy of the respective hearing impairment. It consists in principle of one or more input transducers, of a signal processing device, of an amplification device, and of an output transducer. The input transducer is typically a sound receiver, e.g. a microphone, and / or an electromagnetic receiver, e.g. an induction coil. The output signal generator is usually as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized. He is also referred to as a handset or receiver. The output signal generator generates output signals that are routed to the patient's ear and are intended to produce a hearing perception in the patient. The amplifier is usually integrated in the signal processing device. The hearing aid is powered by a battery integrated into the hearing aid housing. The essential components of a hearing aid are usually arranged on a printed circuit board as a circuit carrier or connected thereto.

Hörinstrumente können außer als Hörgerät, welches der Kompensation eines geschwächten oder beeinträchtigen Hörvermögens, üblicherweise als Schwerhörigkeit bezeichnet, dient, auch als sogenannte Tinnitus-Masker ausgeführt sein. Tinnitus-Masker werden zu Therapie von Tinnitus-Patienten verwendet. Sie erzeugen von der jeweiligen Hörbeeinträchtigung und je nach Wirkprinzip auch von Umgebungsgeräuschen abhängige akustische Ausgangssignale, die zur Verringerung der Wahrnehmung störender Tinnitus- oder sonstiger Ohrgeräusche beitragen können. Im folgenden sollen unter dem Begriff Hörinstrument auch Tinnitus-Masker und sonstige derartige Geräte verstanden werden.Hearing instruments can be designed as a hearing aid, which is the compensation of a weakened or impaired hearing, commonly referred to as deafness, may also be designed as a so-called tinnitus masker. Tinnitus maskers are used to treat tinnitus patients. They produce from the respective hearing impairment and depending on the principle of action also dependent on ambient noise acoustic Output signals that may contribute to reducing the perception of annoying tinnitus or other ear noises. In the following, the term hearing instrument should also be understood tinnitus masker and other such devices.

Hörgeräte sind in verschiedenen grundlegenden Gehäuse-Konfigurationen bekannt. Bei IdO-Hörgeräten (In-dem-Ohr, Inthe-Ear) wird ein Gehäuse, das sämtliche funktionalen Komponenten einschließlich Mikrofon und Receiver enthält, größtenteils im Gehörgang getragen. CiC-Hörgeräte (Completely-in-Canal) sind den IdO-Hörgeräten ähnlich, werden jedoch vollständig im Gehörgang getragen. Bei HdO-Hörgeräten (Hinterdem-Ohr, Behind-the-Ear) wird ein Gehäuse mit Komponenten wie Batterie und Signalverarbeitungseinrichtung hinter dem Ohr getragen und ein flexibler Schallschlauch, auch als Tube bezeichnet, leitet die akustischen Ausgangssignale eines Receivers vom Gehäuse zum Gehörgang. RiC-BtE-Hörgeräte (Receiver-in-Canal Behind-the-Ear) gleichen den HdO-Hörgeräten, jedoch wird der Receiver im Gehörgang getragen und statt eines Schallschlauchs leitet ein flexibler Hörerschlauch elektrische Signale anstelle akustischer Signale zum Receiver, welcher vorne am Hörerschlauch angebracht ist. Allen Gehäuse-Konfigurationen ist gemein, dass möglichst kleine Gehäuse angestrebt werden, um den Tragekomfort zu erhöhen und die Sichtbarkeit des Hörgeräts aus kosmetischen Gründen zu reduzieren.Hearing aids are known in various basic housing configurations. In the case of ITE hearing aids (in-the-ear, in-ear), a housing containing all the functional components, including the microphone and receiver, is mostly worn in the ear canal. Completely-in-Canal (CiC) hearing aids are similar to the IdO hearing aids, but are fully worn in the ear canal. In BTE hearing aids (behind-the-ear, behind-the-ear) a housing with components such as battery and signal processing device behind the ear is worn and a flexible sound tube, also referred to as tube, directs the acoustic output signals of a receiver from the housing to the ear canal. RiC-BtE hearing aids (receiver-in-canal behind-the-ear) are similar to BTE hearing aids, but the receiver is worn in the ear canal and instead of a sound tube, a flexible earpiece tube conducts electrical signals instead of acoustic signals to the receiver, which is at the front of the earpiece tube is appropriate. All housing configurations have in common is that as small a housing as possible be sought in order to increase the comfort and to reduce the visibility of the hearing aid for cosmetic reasons.

Tief-Ohrkanal-Hörgeräte gleichen den CiC-Hörgeräten. Während CiC-Hörgeräte jedoch in der Regel im außenliegenden Teil des äußeren Gehörgangs getragen werden, werden Tief-Ohrkanal-Hörgeräte weiter zum Trommelfell hin vorgeschoben und mindestens teilweise im innenliegenden Teil des äußeren Gehörgangs getragen. Der äußere Gehörgang ist ein mit Haut ausgekleideter Kanal und verbindet die Ohrmuschel mit dem Trommelfell. Im äußeren, distalen Teil des Gehörgangs, der sich direkt an die Ohrmuschel anschließt, ist dieser Kanal aus elastischem Knorpel gebildet. Im inneren, proximalen Teil wird der Kanal vom Schläfenbein gebildet und besteht somit aus Knochen. Der knorpelige und der knöcherne Teil des Gehörgangs sind gegeneinander etwas abgeknickt, so dass sie einen von Person zu Person unterschiedlichen Winkel einschließen. Insbesondere der knöcherne Teil des Gehörgangs ist verhältnismäßig empfindlich gegen Druck und Berührungen. Tief-Ohrkanal-Hörgeräte werden zumindest teilweise im empfindlichen knöchernen Teil des Gehörgangs getragen. Beim Vorschieben in den knöchernen Teil des Gehörgangs müssen sie außerdem den erwähnten Knick passieren, was je nach Winkel des Knicks schwierig sein kann. Zudem können kleine Durchmesser und gewundene Formen des Gehörgangs das Vorschieben weiter erschweren. Tief-Ohrkanal-Hörgeräte müssen daher sehr klein sein.Deep-ear canal hearing aids are similar to the CiC hearing aids. However, while CiC hearing aids are typically worn in the outer portion of the external ear canal, deep ear canal hearing aids are advanced further toward the eardrum and at least partially supported in the inward portion of the external ear canal. The outer ear canal is a skin-lined canal connecting the pinna to the eardrum. In the outer, distal part of the ear canal, which connects directly to the auricle, this channel is formed of elastic cartilage. In the inner, proximal part of the channel is formed by the temporal bone and thus consists of bone. Of the The cartilaginous and bony parts of the ear canal are slightly bent towards each other so that they enclose a different angle from person to person. In particular, the bony part of the ear canal is relatively sensitive to pressure and contact. Deep-ear canal hearing aids are at least partially worn in the delicate bony part of the ear canal. When advancing into the bony part of the ear canal, they must also pass the mentioned kink, which can be difficult depending on the angle of the kink. In addition, small diameter and tortuous shapes of the ear canal can further complicate advancement. Deep-ear canal hearing aids must therefore be very small.

Aus der Druckschrift US 6,865,279 B2 ist ein Ohrkanal-Hörgerät bekannt, das flexibel biegbar ausgeführt ist, um sich dem Gehörgang anpassen zu können. Die elektronischen Komponenten des Hörgeräts sind in unterschiedlichen und gegeneinander flexibel biegbaren Gehäuseteilen angeordnet. Die flexible Biegeverbindung unterliegt elastischen Rückverformungskräften, die je nach Sitz im Gehörgang einen als unangenehm empfundenen Druck des Hörgeräts auf die Gehörgangwand verursachen.From the publication US 6,865,279 B2 an ear canal hearing aid is known, which is flexibly flexible designed to be able to adapt to the ear canal. The electronic components of the hearing aid are arranged in different and mutually flexibly bendable housing parts. The flexible bending connection is subject to elastic restoring forces which, depending on the seat in the auditory canal, cause the hearing device to feel uncomfortable pressure on the auditory canal wall.

Aus der Druckschrift US 2007/0036379 A1 ist ein CiC-Hörgerät zum tragen im knöchernen Teil des Gehörgangs bekannt. Um den Sitz im Gehörgang zu verbessern, weist das Gehäuse des Hörgeräts ebenfalls einen flexibel biegbaren Abschnitt auf.From the publication US 2007/0036379 A1 is a CiC hearing aid known to wear in the bony part of the ear canal. In order to improve the seat in the ear canal, the housing of the hearing aid also has a flexibly bendable section.

Aus der Druckschrift US 4,739,512 A ist ein Hörgerät bekannt, bei dem der Receiver im proximalen Ende des Gehäuses angeordnet ist. Das Hörgerät besitzt ein mehrteiliges Gehäuse und der Receiver ist in eigens dafür vorgesehenen Teilen des Gehäuses installiert.From the publication US 4,739,512 A a hearing aid is known in which the receiver is arranged in the proximal end of the housing. The hearing aid has a multi-part housing and the receiver is installed in specially designed parts of the housing.

Aus der Druckschrift US 6,940,989 B1 ist ein Hörgerät bekannt, bei dem das Trommelfell mittels einer direkten Kopplung stimuliert wird. Ein Receiver ist nicht vorgesehen.From the publication US Pat. No. 6,940,989 B1 a hearing aid is known in which the eardrum is stimulated by means of a direct coupling. A receiver is not provided.

Aus der Druckschrift DE 600 21 553 T2 ist ein Hörgerät bekannt, bei dem der Receiver im proximalen Ende des Gehäuses oder einem eigens dafür vorgesehenen Gehäuseteil angeordnet ist.From the publication DE 600 21 553 T2 a hearing aid is known in which the receiver is arranged in the proximal end of the housing or a housing part specially provided for this purpose.

Aus der Druckschrift DE 36 14 739 A1 ist ein Hörgerät bekannt, bei dem der Receiver mittels eines elastischen Elements im Gehäuse aufgehängt ist. Das elastische Element wird auf den Schallausgang des Receivers aufgesteckt.From the publication DE 36 14 739 A1 a hearing aid is known in which the receiver is suspended by means of an elastic element in the housing. The elastic element is plugged onto the sound output of the receiver.

Die Aufgabe der Erfindung besteht darin, ein Tief-Ohrkanal-Hörinstrument anzugeben, das unaufwändig in Herstellung und Einsatz ist, das eine kleine Baugröße aufweist, und das komfortabel tief im Gehörgang, insbesondere auch im knöchernen Teil des Gehörgangs, zu tragen ist.The object of the invention is to provide a deep-ear canal hearing instrument that is inexpensive to manufacture and use, which has a small size, and comfortable deep in the ear canal, especially in the bony part of the ear canal is to be worn.

Die Erfindung löst diese Aufgabe durch ein Hörinstrument mit den Merkmalen des unabhängigen Patentanspruchs.The invention solves this problem by a hearing instrument having the features of the independent claim.

Ein Grundgedanke der Erfindung besteht in einem Hörinstrument zum Tragen ihm Ohrkanal mit einem Gehäuse, einer Signalverarbeitungseinrichtung, und einem Receiver. Die Signalverarbeitungseinrichtung ist in dem Gehäuse angeordnet. Der Receiver ist teilweise in dem Gehäuse und teilweise außerhalb des Gehäuses angeordnet.A basic idea of the invention consists in a hearing instrument for carrying its ear canal with a housing, a signal processing device, and a receiver. The signal processing device is arranged in the housing. The receiver is partially disposed in the housing and partially outside the housing.

Dadurch, dass der Receiver nur teilweise im Gehäuse angeordnet ist, ist er also nicht vollständig vom Gehäuse umschlossen. Damit kann das Gehäuse insgesamt kleiner gestaltet werden. In dem Bereich, in dem der Receiver außerhalb des Gehäuses angeordnet ist, entfällt die doppelte Wandung in Gestalt der Receiverwand einerseits und der Gehäusewand andererseits, was zusätzlich die Baugröße zu reduzieren hilft. Insbesondere im proximal zu tragenden Bereich des Hörinstruments, der bestimmungsgemäß bis in den knöchernen Teil eines Gehörgangs eingeführt werden kann, ist jedwede Reduzierung der Baugröße hilfreich, um das Einführen des Hörinstruments zu erleichtern und um Irritationen in diesem empfindlichen Teil des Gehörgangs durch das dauerhafte Tragen des Hörinstruments darin zu vermeiden. Zusätzlich kann die lediglich teilweise im Inneren des Gehäuses vorgesehene Anordnung des Receivers je nach Ausführung eine unaufwändigere Fertigung ermöglichen, da der Receiver nicht in einer vom Gehäuse vollständig umschlossenen Anordnung montiert wird und somit je nach Ausführung auch nachträglich, z.B. zu Servicezwecken, von außerhalb des Gehäuses zugänglich sein oder ausgewechselt werden kann.The fact that the receiver is only partially arranged in the housing, so it is not completely enclosed by the housing. Thus, the housing can be made smaller overall. In the area in which the receiver is arranged outside the housing, eliminates the double wall in the form of the receiver wall on the one hand and the housing wall on the other hand, which also helps to reduce the size. In particular, in the proximal to the bearing portion of the hearing instrument, which can be introduced as intended into the bony part of an ear canal, any reduction in size is helpful to facilitate the insertion of the hearing instrument and irritation in this sensitive part of the ear canal by permanently wearing the hearing instrument in it. In addition, the only partially provided inside the housing arrangement of the receiver depending on the design allow a less expensive production, since the receiver is not mounted in a completely enclosed by the housing arrangement and thus depending on the design also later, for example for service purposes, from outside the housing be accessible or replaced.

In einer vorteilhaften Weiterbildung ist der Receiver in einer Öffnung des Gehäuses angeordnet. Je nach Ausgestaltung der Öffnung ist der Receiver damit nicht bloß im außerhalb des Gehäuses angeordneten Teil von außen zugänglich, sondern kann auch von außen montiert oder entnommen und ausgewechselt werden, ohne das Gehäuse öffnen zu müssen.In an advantageous development of the receiver is arranged in an opening of the housing. Depending on the configuration of the opening of the receiver is thus not only accessible in the outside of the housing arranged part accessible from the outside, but can also be mounted or removed from the outside and replaced without having to open the housing.

In einer weiteren vorteilhaften Weiterbildung weist der Receiver auf seinem Außenumfang einen Vorsprung, z.B. eine umlaufende Manschette. Der Vorsprung steht mit einer Hinterschneidung in der Öffnung in gegenseitigem Eingriff, z.B. einer umlaufenden Nut. Die Hinterschneidung ist derart ausgebildet, dass der Receiver durch den gegenseitigen Eingriff gegen ein Herausgleiten aus der Öffnung fixiert wird. Ein solches Zusammenwirken von Vorsprung und Hinterschneidung mit einer Nut-Feder-Verbindung stellt eine unaufwändige und sichere mechanische Befestigung dar, die den Verzicht auf eine aufwändigere Fixierung des Receivers, z.B. durch Verkleben, ermöglicht.In a further advantageous development, the receiver has on its outer circumference a projection, for example a circumferential sleeve. The projection stands with an undercut in the opening in mutual engagement, eg a circumferential groove. The undercut is formed such that the receiver is fixed by the mutual engagement against slipping out of the opening. Such an interaction of projection and undercut with a tongue and groove connection represents an inexpensive and secure mechanical attachment, which allows the waiver of a more complex fixation of the receiver, for example by gluing.

Hearing aid in the ear canal.

In Figur 1 ist ein Hörinstrument nach dem Stand der Technik schematisch dargestellt, das als Ohrkanal-Hörgerät 1 ausgeführt ist. Es umfasst ein Gehäuse 7, das eine zum Einführen und Tragen im Gehörgang geeignete Gehäuseform aufweist. Je nach Größe, Form und Durchmesser des Gehäuses 7 kann das Hörgerät 1 weiter oder weniger weit in den Gehörgang eines Hörgeräteträgers eingeführt werden. Bei ausreichend kleinen Abmessungen kann das Hörgerät 1 bis zum oder in den knöchernen Teil des Gehörgangs eingeführt werden, so dass dann ein Tief-Ohrkanal-Hörgerät vorliegt.In FIG. 1 a hearing instrument of the prior art is schematically shown, which is designed as ear canal hearing aid. 1 It comprises a housing 7 which has a housing shape suitable for insertion and carrying in the ear canal. Depending on the size, shape and diameter of the housing 7, the hearing aid 1 can be further or less widely inserted into the ear canal of a hearing aid wearer. If the dimensions are sufficiently small, the hearing device 1 can be inserted as far as or into the bony part of the auditory canal, so that then a deep-ear canal hearing device is present.

Das Gehäuse 7 ist in der Regel aus Kunststoff gefertigt und kann individuell an die Konturen eines Gehörgangs eines Hörgeräteträgers angepasst sein. Zu diesem Zweck kann es beispielsweise nach Erfassung von 3D-Daten des Gehörgangs entsprechend diesen Daten per Spritzgussverfahren oder in einer Rapid-Prototyping-Technologie per RSM-Verfahren (Rapid-Shell-Manufacturing) hergestellt sein. Um den Tragekomfort zu erhöhen, kann der Außenumfang des Gehäuses 7 flexibel ausgeführt sein oder einen flexiblen Überzug oder Ummantelung aufweisen. Als hierfür geeignetes weiches und flexibles Material kommen beispielsweise Silikongele in Betracht.The housing 7 is usually made of plastic and can be adapted individually to the contours of an ear canal of a hearing aid wearer. For this purpose, it may be produced, for example, after acquisition of 3D data of the auditory canal in accordance with this data by injection molding or in a rapid prototyping technology by means of the RSM process (Rapid Shell Manufacturing). In order to increase the wearing comfort, the outer circumference of the housing 7 can be made flexible be or have a flexible coating or sheath. As suitable soft and flexible material, for example, silicone gels are considered.

Im Gehäuse 7 ist ein Mikrofon 4 zum Aufnehmen von Umgebungsschall und umwandeln in elektrische Signale angeordnet. Das Mikrofon 4 ist außgangsseitig mit einem Signaleingang einer ebenfalls im Gehäuse 7 angeordneten Signalverarbeitungseinrichtung 5 verbunden. Die Signalverarbeitungseinrichtung 5 verarbeitet und verstärkt vom Mikrofon 4 empfangene Signale gemäß einem Signalverarbeitgungsalgorithmus, der auch als Hörprogramm bezeichnet wird. Ausgangsseitig ist die Signalverarbeitungseinrichtung 5 mit einem Receiver 2 verbunden, der die von der Signalverarbeitungseinrichtung 5 empfangenen elektrischen Signale in akustische Ausgangssignale umwandelt. Die elektronischen Komponenten im Gehäuse 7 des Hörgeräts 1 werden von einer Batterie 3 mit der erforderlichen Betriebsenergie versorgt. Die Batterie 3 kann eine Einwegbatterie oder ein wiederaufladbarer Akkumulator sein. Die elektronischen Komponenten samt Batterie 3 sind in nicht dargestellter Weise miteinander elektrisch verbunden, z.B. über Verdrahtung oder über einen gemeinsamen starren oder flexiblen Schaltungsträger.In the housing 7, a microphone 4 is arranged for recording ambient sound and convert it into electrical signals. The microphone 4 is the output side connected to a signal input of a likewise arranged in the housing 7 signal processing device 5. The signal processing device 5 processes and amplifies signals received by the microphone 4 in accordance with a signal processing algorithm, which is also referred to as a hearing program. On the output side, the signal processing device 5 is connected to a receiver 2, which converts the electrical signals received by the signal processing device 5 into acoustic output signals. The electronic components in the housing 7 of the hearing aid 1 are supplied by a battery 3 with the required operating energy. The battery 3 may be a disposable battery or a rechargeable battery. The electronic components including battery 3 are electrically connected together in a manner not shown, e.g. via wiring or via a common rigid or flexible circuit carrier.

Der Reveiver 2 gibt die akustischen Ausgangssignale durch eine Receiveröffnung 6 im Gehäuse 7 nach außen ab. Die Receiveröffnung 6 ist in der proximal im Gehörgang zu tragenden Seite des Gehäuses 7 angeordnet, so dass die Ausgangssignale in Richtung des Trommelfells des Hörgeräteträgers abgegeben werden. Der Receiver 2 selbst ist vollständig innerhalb des Gehäuses 7 angeordnet. Mit der Außenseite ist er lediglich über die Receiveröffnung 6 verbunden.The Reveiver 2 outputs the acoustic output signals through a receiver opening 6 in the housing 7 to the outside. The receiver opening 6 is arranged in the proximal side of the housing 7 to be supported in the auditory canal, so that the output signals are emitted in the direction of the eardrum of the hearing aid wearer. The receiver 2 itself is arranged completely inside the housing 7. With the outside it is connected only via the receiver opening 6.

In Figur 2 ist ein als Tief-Ohrkanal-Hörgerät 11 ausgeführtes Hörinstrument mit einem von einer Manschette 20 gehaltenem Receiver 12 schematisch dargestellt. Im Gegensatz zum vorangehend erläuterten Stand der Technik ist der Receiver 12 lediglich teilweise innerhalb des Gehäuses 17 des Hörgeräts 11 angeordnet, teilweise jedoch auch außerhalb. Er ragt aus dem Gehäuse 17 heraus. Das Gehäuse 17 umschließt den Receiver 12 lediglich teilweise, weshalb das Gehäuse 17 eine entsprechend kleinere Baugröße aufweist. Der Receiver 12 ragt aus der proximal im Gehörgang zu tragenden Seite des Gehäuses 11 heraus, so dass der Durchmesser des Hörgeräts 11 im proximalen Bereich auf den Durchmesser des herausragenden Teils des Receivers 12 reduziert ist.In FIG. 2 a hearing instrument designed as a deep-ear canal hearing device 11 is shown schematically with a receiver 12 held by a cuff 20. In contrast to the prior art explained above, the receiver 12 is only partially within the housing 17 of the hearing device 11 arranged, but sometimes outside. He sticks out of the housing 17. The housing 17 surrounds the receiver 12 only partially, which is why the housing 17 has a correspondingly smaller size. The receiver 12 projects out of the proximal side of the housing 11 to be supported in the auditory canal, so that the diameter of the hearing device 11 in the proximal region is reduced to the diameter of the protruding part of the receiver 12.

Der Receiver 12 ist in einer Öffnung 18 des Gehäuses 11 angeordnet. In der Öffnung 18 ist eine umlaufende Vertiefung, die als umlaufende Nut 19 ausgeführt ist, vorgesehen. Der Receiver 12 weist seinerseits einen auf seinem Außenumfang umlaufenden Vorsprung, der als Manschette 20 ausgeführt ist, auf. Die Manschette 20 ist in die Nut 19 eingeführt und steht daher mit dieser in gegenseitigem Eingriff. Da Nut 19 und Manschette 20 quer zur Längserstreckung der Öffnung 18 orientiert sind, ist der Receiver 12 wegen des gegenseitigen Eingriffs der beiden gegen Herausgleiten aus der Öffnung 18 fixiert.The receiver 12 is arranged in an opening 18 of the housing 11. In the opening 18, a circumferential recess, which is designed as a circumferential groove 19, is provided. The receiver 12 in turn has a peripheral on its outer circumference projection, which is designed as a sleeve 20 on. The sleeve 20 is inserted into the groove 19 and therefore is in mutual engagement with this. Since the groove 19 and sleeve 20 are oriented transversely to the longitudinal extent of the opening 18, the receiver 12 is fixed because of the mutual engagement of the two against sliding out of the opening 18.

Neben einem Teil des Receivers 12 sind im Gehäuse 11 eine Batterie 13, ein Mikrofon 14, und eine Signalverarbeitungseinrichtung 15 angeordnet. Bezüglich Einzelheiten der genannten Komponenten wird auf die vorangehende Erläuterung zum Stand der Technik verwiesen.In addition to a part of the receiver 12, a battery 13, a microphone 14, and a signal processing device 15 are arranged in the housing 11. For details of said components, reference is made to the preceding explanation of the prior art.

In Figur 3 ist als Tief-Ohrkanal-Hörgerät 21 ausgeführtes Hörinstrument schematisch dargestellt. Bezüglich Einzelheiten zu den elektronischen Komponenten Batterie 23, Mikrofon 24, Signalverarbeitungseinrichtung 25 und Receiver 22 wird wiederum auf die vorangehende Erläuterung zum Stand der Technik verwiesen.In FIG. 3 is shown as a deep-ear canal hearing aid 21 executed hearing aid schematically. With regard to details of the electronic components battery 23, microphone 24, signal processing device 25 and receiver 22, reference is again made to the preceding explanation of the prior art.

Der Receiver 22 ist auch in dieser Ausführung lediglich teilweise innerhalb des Gehäuses 17, und teilweise außerhalb des Gehäuses 27 angeordnet. Er ist jedoch nicht durch einen Nut-Feder-Mechanismus wie vorangehend erläutert in der Öffnung 28 fixiert. Stattdessen ist der Receiver 22 entweder durch eine (leichte) Presspassung kraftschlüssig in der Öffnung 28 fixiert, oder er ist verklebt.The receiver 22 is also only partially disposed within the housing 17, and partially outside of the housing 27 in this embodiment. However, it is not through a tongue and groove mechanism as previously explained in the opening 28th fixed. Instead, the receiver 22 is either fixed by a (slight) press fit frictionally in the opening 28, or it is glued.

In Figur 4 ist ein Tief-Ohrkanal-Hörgerät 31 mit wie vorangehend erläutert teilweise außerhalb des Gehäuses angeordnetem Receiver im bestimmungsgemäßen Gebrauch im Gehörgang eines Hörgeräteträgers schematisch dargestellt. Der Gehörgang wird im distalen Bereich durch den knorpeligen Abschnitt 40 und im proximalen Bereich durch den knöchernen Abschnitt 41 gebildet. In proximaler Richtung wird er durch das Trommelfell 42 abgeschlossen. Das Tief-Ohrkanal-Hörgerät 31 ist bis in den knöchernen Gehörgangabschnitt 41 eingeführt. Bis in diesen Abschnitt ist vor allem der aus dem Hörgerät 31 herausragende Teil des Receivers vorgeschoben. Der Receiver weist kleinere Abmessungen als das Gehäuse des Hörgeräts 31 auf, so dass er ohne Berührung mit der Gehörgangwand frei in den Gehörgang ragt. Durch diese Positionierung wird eine Irritation des empfindlichen knöchernen Gehörgangabschnitts 41 aufgrund von Berührung mit dem Hörgerät 31 oder Receiver vermieden. Gleichzeitig ist eine Positionierung tief im Ohrkanal erreicht.In FIG. 4 is a deep-ear canal hearing aid 31 with schematically explained as explained above outside the housing receiver in the intended use in the ear canal of a hearing aid wearer. The auditory canal is formed in the distal region by the cartilaginous portion 40 and in the proximal region by the bony portion 41. In the proximal direction, it is closed by the eardrum 42. The deep-ear canal hearing aid 31 is inserted into the bony ear canal section 41. Up to this section, especially the projecting from the hearing aid 31 part of the receiver is advanced. The receiver has smaller dimensions than the housing of the hearing aid 31, so that it protrudes freely into the auditory canal without contact with the auditory canal wall. This positioning avoids irritation of the sensitive bony ear canal section 41 due to contact with the hearing device 31 or receiver. At the same time, positioning is achieved deep in the ear canal.

Ein Grundgedanke der Erfindung lässt sich wie folgt zusammenfassen: Die Erfindung betrifft ein Tief-Ohrkanal-Hörinstrument, insbesondere ein Hörgerät, zum Tragen tief im Ohrkanal eines Benutzers. Die Aufgabe der Erfindung besteht darin, ein Tief-Ohrkanal-Hörinstrument anzugeben, das unaufwändig in Herstellung und Einsatz ist, das eine kleine Baugröße aufweist, und das komfortabel tief im Gehörgang, insbesondere auch im knöchernen Teil des Gehörgangs, zu tragen ist. Die Erfindung löst diese Aufgabe durch ein Hörinstrument mit einem Gehäuse (17,27), einer Signalverarbeitungseinrichtung (15,25), und einem Receiver (12,22). Die Signalverarbeitungseinrichtung (15,25) ist in dem Gehäuse (17,27) angeordnet. Der Receiver (12,22) ist lediglich teilweise in dem Gehäuse (17,27) und andernteils außerhalb des Gehäuses (17,27) angeordnet. Dadurch, dass der Receiver (12,22) nur teilweise im Gehäuse (17,27) angeordnet ist, ist er also nicht vollständig vom Gehäuse (17,27) umschlossen. Damit kann das Gehäuse (17,27) insgesamt kleiner gestaltet werden. In dem Bereich, in dem der Receiver (12,22) außerhalb des Gehäuses (17,27) angeordnet ist, entfällt die doppelte Wandung in Gestalt der Receiverwand einerseits und der Gehäusewand andererseits, was zusätzlich die Baugröße zu reduzieren hilft.A basic idea of the invention can be summarized as follows: The invention relates to a deep-ear canal hearing instrument, in particular a hearing aid, for wearing deep in the ear canal of a user. The object of the invention is to provide a deep-ear canal hearing instrument that is inexpensive to manufacture and use, which has a small size, and comfortable deep in the ear canal, especially in the bony part of the ear canal is to be worn. The invention achieves this object by means of a hearing instrument having a housing (17, 17), a signal processing device (15, 25), and a receiver (12, 22). The signal processing device (15,25) is arranged in the housing (17,27). The receiver (12,22) is only partially in the housing (17,27) and partly outside of the housing (17,27) arranged. Because the receiver (12,22) only partially is arranged in the housing (17,27), so it is not completely enclosed by the housing (17,27). Thus, the housing (17,27) can be made smaller overall. In the area in which the receiver (12,22) outside the housing (17,27) is arranged, eliminates the double wall in the form of the receiver wall on the one hand and the housing wall on the other hand, which also helps to reduce the size.
