Description

Die vorliegende Erfindung betrifft ein IdO-Hörgerät zur binauralen Versorgung eines Patienten mit einem Gehäuse und einer Antennenvorrichtung, die eine bevorzugte Übertragungsrichtung aufweist.The present invention relates to an ITE hearing aid for binaurally supplying a patient with a housing and an antenna device having a preferred transmission direction.

Bei IdO-Hörgeräten besteht grundsätzlich die Problematik, dass nur sehr wenig Bauraum zur Verfügung steht. Daher sind die in den IdO-Hörgeräten notwendigen Komponenten möglichst klein zu gestalten bzw. auf ein Minimum zu reduzieren.In the case of ITE hearing aids, there is basically the problem that only very little installation space is available. Therefore, the components required in the ITE hearing aids are to be as small as possible or kept to a minimum.

Bei binauraler Versorgung besteht des Weiteren die Anforderung, dass die beiden Hörgeräte in ihren Einstellungen aufeinander abgestimmt werden müssen. Falls die IdO-Hörgeräte Mechanismen besitzen, sich selbst automatisch auf bestimmte Hörsituationen einzustellen, sollte die Einstellung der beiden Hörgeräte aufeinander abgestimmt erfolgen.In the case of binaural supply, there is also the requirement that the two hearing aids must be matched in their settings. If the IdO hearing aids have mechanisms to automatically adjust themselves to certain listening situations, the adjustment of the two hearing aids should be coordinated.

Aus der Druckschrift DE 100 48 354 A1 ist ein Hörgerätesystem mit zwei Hörgeräten bekannt. Die Hörgeräte sind durch einen bidirektionalen, drahtlosen Signalpfad verbunden. Auch aus der Patentschrift US 6 549 633 ist ein binaurales Hörhilfesystem bekannt, bei dem zwei Hörgeräte bidirektional und drahtlos miteinander verbunden sind.From the publication DE 100 48 354 A1 is a hearing aid system with two hearing aids known. The hearing aids are connected by a bidirectional wireless signal path. Also from the patent US Pat. No. 6,549,633 a binaural hearing aid system is known in which two hearing aids are connected bidirectionally and wirelessly.

Ferner ist in der Druckschrift DE 102 36 940 B3 eine platzsparende Antennenanordnung für Hörhilfegeräte offenbart. Dabei ist eine Antennenspule auf den Hörer oder auf das Mikrofon gewickelt.Furthermore, in the document DE 102 36 940 B3 discloses a space-saving antenna arrangement for hearing aids. An antenna coil is wound on the receiver or on the microphone.

In der WO 03/032682 A wird ein IdO-Hörgerät mit einer integrierten Antennenvorrichtung, die als Richtantenne ausgebildet sein kann, offenbart. Die Antenne wird zur Datenübertragung zu einem anderen Hörgerät oder zur Aufnahme von Funksignalen aus der Umgebung verwendet.In the WO 03/032682 A is an ITE hearing aid with an integrated antenna device, which may be designed as a directional antenna disclosed. The antenna is for data transmission used to another hearing aid or for recording radio signals from the environment.

Aus der US 2003/152243 A1 ein Hörgerät mit einer induktiven Antenne bekannt.From the US 2003/152243 A1 a hearing aid with an inductive antenna known.

Die EP-A-0 941 014 offenbart ein Hörgerätesystem mit zwei Hörhilfegeräten, bei dem Antennenspulen zur binauralen Versorgung verwendet wird.The EP-A-0 941 014 discloses a hearing aid system with two hearing aids, is used in the antenna coils for binaural supply.

In der DE 23 60 342 B1 wird ein Hörgerät offenbart, bei dem eine Antennenspule in einer Hörbrille angeordnet ist.In the DE 23 60 342 B1 a hearing aid is disclosed in which an antenna coil is arranged in a hearing glasses.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, ein IdO-Hörgerät vorzuschlagen, das zur Kommunikation mit einem anderen IdO-Hörgerät in der Lage ist.The object of the present invention is thus to propose an ITE hearing aid that is capable of communicating with another ITE hearing aid.

Erfindungsgemäß wird diese Aufgabe gelöst durch ein IdO-Hörgerät zur binauralen Versorgung eines Patienten mit einem Gehäuse und einer Antennenvorrichtung, die eine bevorzugte Übertragungsrichtung aufweist, wobei die Antennenvorrichtung in dem Gehäuse derart angeordnet ist, dass die bevorzugte Übertragungsrichtung in einem an oder in das erste Ohr des Patienten angebrachten bzw. eingesetzten Zustand des Hörgeräts im Wesentlichen zu dem zweiten Ohr des Patienten weist.According to the invention, this object is achieved by an ITE hearing aid for binaurally supplying a patient with a housing and an antenna device having a preferred transmission direction, wherein the antenna device is arranged in the housing such that the preferred transmission direction in or on the first ear the patient attached or inserted state of the hearing substantially to the second ear of the patient has.

Als Halteeinrichtung für die Antennenvorrichtung kann eine Batteriefeder zum Kontaktieren einer Hörgerätebatterie verwendet werden. Hierzu wird an die Batteriefeder eine Ausleger angebracht, an die die Antennenvorrichtung befestigt werden kann. Somit lässt sich eine stabile Befestigung der Antennenvorrichtung gewährleisten.As a holding device for the antenna device, a battery spring for contacting a hearing aid battery can be used. For this purpose, a boom is attached to the battery spring, to which the antenna device can be attached. Thus, a stable attachment of the antenna device can be ensured.

Alternativ kann die Befestigung der Antennenvorrichtung auf den Programmierkontakten des Hörgeräts erfolgen. Hierzu wird ein spezieller Adapter, an dem die Antennenvorrichtung befestigt oder befestigbar ist, auf die Programmierkontakte aufgesetzt. Diese Befestigungsmöglichkeit kann bei bestimmten Hörgeräteaufbauten von Vorteil sein, wenn nur im Bereich der Programmierkontakte Einbauraum für die Antennenvorrichtung zur Verfügung steht. Darüber hinaus hat diese Befestigungsvariante den Vorteil der einfachen Montage.Alternatively, the attachment of the antenna device can be made on the programming contacts of the hearing aid. For this purpose, a special adapter is attached to the antenna device or attachable, placed on the programming contacts. This mounting option may be advantageous in certain hearing aid designs, if installation space for the antenna device is available only in the area of the programming contacts. In addition, this attachment variant has the advantage of easy installation.

Erfindungsgemäß ist somit die Antenne zur Kommunikation der beiden Hörgeräte für binaurale Versorgung in einer genau definierten Lage, d. h. in einem bestimmten Winkel zum Gehäuse in dem IdO-Hörgerät eingebaut. Auf diese Weise lässt sich eine energiesparende Übertragung zwischen den beiden IdO-Hörgeräten realisieren, da die Übertragungsrichtungen der Antennen der beiden Hörgeräte aufeinander abgestimmt sind.Thus, according to the invention, the antenna for communicating the two hearing aids for binaural care in a well-defined position, d. H. installed at a certain angle to the housing in the ITE hearing aid. In this way, an energy-saving transmission between the two ITE hearing aids can be realized, since the transmission directions of the antennas of the two hearing aids are matched to one another.

Vorzugsweise umfasst die Antennenvorrichtung eine Antennenspule. Mit dieser Antennenspule ist es möglich, eine elektromagnetische Übertragungsstrecke zwischen den beiden Hörgeräten bei einer binauralen Versorgung aufzubauen.Preferably, the antenna device comprises an antenna coil. With this antenna coil, it is possible to build an electromagnetic transmission path between the two hearing aids in a binaural supply.

Bei dem IdO-Hörgerät kann es sich um ein sogenanntes CIC-Hörgerät handeln, das sich vollständig in den Gehörgang des Patienten einsetzen lässt. Dies bedeutet, dass die Antenne wegen der speziellen Ausrichtung selbst in ein CIC-Gerät eingebaut werden kann.The IdO hearing aid can be a so-called CIC hearing aid that can be inserted completely into the auditory canal of the patient. This means that the antenna itself can be built into a CIC device because of its special orientation.

Das IdO-Hörgerät weist typischerweise eine Montageplatte auf, wobei die Antennenvorrichtung in einem Winkel von 10 bis 40° zur Senkrechten der Montageplatte angeordnet ist. Vorzugsweise liegt dieser Winkel bei etwa 20 bis 30°. Dieser Winkel entspricht dem typischen Neigungswinkel des Gehörgangs relativ zur Verbindungslinie der beiden Ohren eines Patienten. Die Montageplatten der Hörgeräte, die im linken und rechten Ohr des Patienten eingesetzt sind, sind üblicherweise etwa parallel zueinander ausgerichtet. Wenn daher die Antennenvorrichtung mit ihrer bevorzugten Übertragungsrichtung den oben genannten Winkel zur Montageplatte aufweist, liegen die Übertragungsrichtungen der beiden Hörgeräte im eingesetzten Zustand auf einer Geraden, wobei die Übertragungsrichtungen zueinander entgegengesetzt sind. Dadurch ist eine optimale Übertragung zwischen den beiden Antennenvorrichtungen mit minimalem Energieaufwand möglich. Hierbei ist zu berücksichtigen, dass die Einbauwinkel der Antennen im linken und rechten Hörgerät betragsmäßig gleich sind, aber unterschiedliche Vorzeichen besitzen.The ITE hearing aid typically has a mounting plate, wherein the antenna device is arranged at an angle of 10 to 40 ° to the vertical of the mounting plate. Preferably, this angle is about 20 to 30 °. This angle corresponds to the typical inclination angle of the ear canal relative to the connecting line of the two ears of a patient. The mounting plates of the hearing aids, which are inserted in the left and right ear of the patient, are usually aligned approximately parallel to each other. Therefore, if the antenna device with its preferred transmission direction has the above-mentioned angle to the mounting plate, the transmission directions are the two hearing aids in the inserted state on a straight line, wherein the transmission directions are opposite to each other. As a result, optimum transmission between the two antenna devices with minimal energy consumption is possible. It should be noted that the installation angle of the antennas in the left and right hearing aid are equal in magnitude, but have different signs.

Als Halteeinrichtung für die Antennenvorrichtung kann eine Batteriefeder zum Kontaktieren einer Hörgerätebatterie verwendet werden. Hierzu wird an die Batteriefeder ein Ausleger angebracht, an dem die Antennenvorrichtung befestigt werden kann. Somit lässt sich eine stabile Befestigung der Antennenvorrichtung gewährleisten.As a holding device for the antenna device, a battery spring for contacting a hearing aid battery can be used. For this purpose, a boom is attached to the battery spring, to which the antenna device can be attached. Thus, a stable attachment of the antenna device can be ensured.

Alternativ kann die Befestigung der Antennenvorrichtung auf den Programmierkontakten des Hörgeräts erfolgen. Hierzu wird ein spezieller Adapter, an dem die Antennenvorrichtung befestigt oder befestigbar ist, auf die Programmierkontakte aufgesetzt. Diese Befestigungsmöglichkeit kann bei bestimmten Hörgeräteaufbauten von Vorteil sein, wenn nur im Bereich der Programmierkontakte Einbauraum für die Antennenvorrichtung zur Verfügung steht. Darüber hinaus hat diese Befestigungsvariante den Vorteil der einfachen Montage.Alternatively, the attachment of the antenna device can be made on the programming contacts of the hearing aid. For this purpose, a special adapter to which the antenna device is attached or fastened, placed on the programming contacts. This mounting option may be advantageous in certain hearing aid designs, if installation space for the antenna device is available only in the area of the programming contacts. In addition, this attachment variant has the advantage of easy installation.

Die vorliegende Erfindung wird nun anhand der beigefügten Zeichnungen näher erläutert, in denen zeigen:

FIG 1
eine perspektivische Ansicht der auf einer Montage- platte montierten Elektronikkomponenten eines IdO- Hörgeräts einschließlich Antenne; und
FIG 2
eine Ansicht der Elektronikkomponenten von FIG 1 aus einem anderen Blickwinkel.
The present invention will now be explained in more detail with reference to the accompanying drawings, in which:
FIG. 1
a perspective view of mounted on a mounting plate electronic components of an ITE hearing aid including antenna; and
FIG. 2
a view of the electronic components of FIG. 1 from a different angle.

Die nachfolgend näher geschilderten Ausführungsbeispiele stellen bevorzugte Ausführungsformen der vorliegenden Erfindung dar.The embodiments described in more detail below represent preferred embodiments of the present invention.

Entsprechend FIG 1 sind auf bzw. an einer Montageplatte M, die im Endzustand bei der Fertigung des Hörgeräts individuell auf die Kontur des Ohrpassstücks zugeschnitten ist und als face plate bezeichnet wird, Elektronikkomponenten des Hörgeräts befestigt. Insbesondere ragt die Batterie B durch die Montageplatte M. Sie wird von einer Batteriefeder BF gehalten. Oberhalb der Batterie B ist ein Elektronikmodul E angedeutet.Corresponding FIG. 1 are on or on a mounting plate M, which is tailored in the final state in the manufacture of the hearing individually to the contour of the earmold and is referred to as a face plate, fixed electronic components of the hearing aid. In particular, the battery B protrudes through the mounting plate M. It is held by a battery spring BF. Above the battery B, an electronic module E is indicated.

An der Batteriefeder BF ist ein Ausleger A befestigt, an dessen distalem Ende eine Klammer K montiert ist. Die Klammer K hält eine Antennenspule AS. Als Abstandshalter zum Lautsprecher ist ein Weichgummistück G1 an der Stirnseite der Antennenspule AS angebracht, welche Seite sich in der Nähe der Klammer K befindet.On the battery spring BF a boom A is attached to the distal end of a bracket K is mounted. The bracket K holds an antenna coil AS. As a spacer to the speaker, a soft rubber piece G1 is attached to the front side of the antenna coil AS, which side is in the vicinity of the bracket K.

Wie aus FIG 1 ebenfalls zu erkennen ist, ist der Ausleger A etwa im Bereich seiner Mitte abgewinkelt, so dass die gewünschte Winkelstellung der Antennenspule AS gegenüber der Montageplatte erreicht wird. Auch die Befestigung des Auslegers A an der Batteriefeder BF kann in einem beliebigen Winkel erfolgen. Somit ist es möglich, der Klemme K und daher auch der Antennenspule AS einen beliebigen räumlichen Winkel gegenüber der Montageplatt M bzw. deren Vertikalen zu geben.How out FIG. 1 can also be seen, the arm A is angled approximately in the region of its center, so that the desired angular position of the antenna coil AS is achieved with respect to the mounting plate. The attachment of the arm A to the battery spring BF can also be done at any angle. Thus, it is possible to give the terminal K and therefore also the antenna coil AS any spatial angle with respect to the mounting plate M and their verticals.

In FIG 2 sind die wesentlichen Komponenten, die auch in FIG 1 dargestellt sind, aus einer anderen Perspektive wiedergegeben, wobei aus Gründen der Übersicht auf die Darstellung des Elektronikmoduls E verzichtet wurde. Speziell sind hier die beiden Batteriefedern BF zu erkennen, zwischen denen die Batterie B gehalten ist. An der linken Batteriefeder BF ist der Ausleger A angeordnet, der die Antennenspule AS in dem gewünschten Winkel α gegenüber der Senkrechten der Montageplatte M hält. Die Antennenvorrichtung (AS) ist auf Programmierkontakte (P) aufgesetzt. Aus FIG 2 ist ferner zu entnehmen, dass die Antennenspule AS auch in eine Richtung senkrecht zur Zeichenebene gekippt ist. Zusammen mit dem Winkel α ergibt sich somit ein spezifischer räumlicher Winkel, der dem statistischen Gehörgangswinkel des Gehörgangs zur Verbindungslinie der beiden Ohren eines Patienten entspricht. Die bevorzugte Übertragungsrichtung der Antennenspule AS liegt entlang ihrer Achse. Wenn daher in dem Hörgerät auf der einen Seite des Hörgeräteträgers die Antennenspule AS in der geschilderten Weise und in dem Hörgerät auf der anderen Seite des Hörgeräteträgers symmetrisch hierzu ausgerichtet ist, so stehen die beiden Antennenspulen zueinander im Wesentlichen koaxial. Dementsprechend kann eine drahtlose Verbindung zwischen beiden Antennenspulen mit minimaler Energie aufgebaut werden.In FIG. 2 are the essential components that are also in FIG. 1 are shown, reproduced from another perspective, was omitted for reasons of clarity on the presentation of the electronic module E. Specifically, the two battery springs BF can be seen here, between which the battery B is held. On the left battery spring BF, the arm A is arranged, the antenna coil AS at the desired angle α with respect to the vertical of the mounting plate M holds. The antenna device (AS) is mounted on programming contacts (P). Out FIG. 2 It can also be seen that the antenna coil AS is also tilted in a direction perpendicular to the plane of the drawing. Together with the angle α thus results in a specific spatial angle corresponding to the statistical auditory canal angle of the ear canal to the connecting line of the two ears of a patient. The preferred transmission direction of the antenna coil AS lies along its axis. Therefore, if in the hearing aid on one side of the hearing aid wearer the antenna coil AS is aligned symmetrically in the manner described and in the hearing aid on the other side of the hearing aid wearer, then the two antenna coils are essentially coaxial to each other. Accordingly, a wireless connection between both antenna coils can be constructed with minimum power.

Alternativ zu dem Ausleger A an der Batteriefeder BF kann zur Halterung der Antennenspule AS in dem gewünschten Winkel auch ein Adapter vorgesehen sein, der auf die Montageplatte M der Hörgeräteelektronik aufgesteckt wird. Selbstverständlich können aber auch andere Komponenten zur Halterung in dem gewünschten Winkel vorgesehen sein.As an alternative to the arm A on the battery spring BF may be provided for holding the antenna coil AS at the desired angle and an adapter which is plugged onto the mounting plate M of the hearing aid electronics. Of course, other components may be provided for mounting in the desired angle.

Um das IdO-Hörgerät möglichst klein zu bauen und die Antenne definiert einbauen zu können, sollte die Antenne gegenüber dem Hörer bzw. Lautsprecher zurückversetzt eingebaut werden. Der Grund hierfür liegt darin, dass die Hörgeräte im Wesentlichen konisch ausgebildet sind und daher nach außen hin mehr Bauraum zur Verfügung steht. Diese Problematik tritt insbesondere bei CIC-Geräten auf, die vollständig in den Gehörgang eingesetzt werden.In order to build the IdO hearing aid as small as possible and to be able to install the antenna in a defined manner, the antenna should be set back in relation to the receiver or loudspeaker. The reason for this is that the hearing aids are substantially conical and therefore more space is available to the outside. This problem occurs especially in CIC devices that are fully inserted into the ear canal.

Aus Montagegründen sollte die Halterung der Antennenspule AS so gestaltet sein, dass die Antennenspule beim Einbau nicht beschädigt wird. Die Klemme K stellt eine derartige schonende Halterung dar.For mounting reasons, the holder of the antenna coil AS should be designed so that the antenna coil when installing not is damaged. The clamp K represents such a gentle holder.

Die Ohrpassstücke für IdO-Hörgeräte werden grundsätzlich individuell angefertigt. Daher steht in jedem Hörgerät ein entsprechend anderer Einbauraum zur Verfügung. Aus mehreren Einbauversuchen hat es sich daher im statistischen Mittel als günstig erwiesen, die Antennenspule AS, wie in FIG 1 und FIG 2 dargestellt, in der Position neben der Batterie mit einer entsprechenden Halterung an der Batteriefeder BF zu befestigen. Somit wird die typische Grundfläche des face-plate-Ausschnitts durch das zusätzliche Bauelement, die Antennenspule AS, nicht vergrößert.The earmolds for ITE hearing aids are always made individually. Therefore, a correspondingly different installation space is available in each hearing aid. From several installation tests, it has therefore proven to be favorable on a statistical average, the antenna coil AS, as in FIG. 1 and FIG. 2 shown to be mounted in the position next to the battery with a corresponding bracket on the battery spring BF. Thus, the typical base area of the face-plate section is not enlarged by the additional component, the antenna coil AS.
