Der in Hörhilfegeräten verwendete sogenannte Hörer arbeitet meist nach dem elektromagnetischen Prinzip. Dazu wird im Hörer ein magnetischer Kreis aufgebaut. Leider werden auch ge ringe magnetische Streufelder in den Außenraum abgestrahlt. Diese ungewollten Störfelder führen zu Wechselwirkungen mit den um den Hörer liegenden Spulen und Leitungen. Es ist daher wünschenswert, die Hörerfelder auf das Hörergehäuse zu beschränken oder zu kompensieren.The so-called listener used in hearing aids works mostly according to the electromagnetic principle. This is in the handset built up a magnetic circuit. Unfortunately, ge Magnetic stray fields radiated to the outside. These unwanted interference fields lead to interactions with the coils and cables around the receiver. It is therefore desirable to limit the handset fields on the listener housing or compensate.

Aufgabe der vorliegenden Erfindung ist es, den Platzbedarf einer Antennenspule für die drahtlose Übertragung von Daten bei einem Hörhilfegerät zu minimieren.Object of the present invention is the space required an antenna coil for the wireless transmission of data to minimize with a hearing aid.

Diese Aufgabe wird bei einem Hörhilfegerät mit wenigstens einem Mikrofon zur Aufnahme eines akustischen Eingangssignals und Wandlung in ein elektrisches Signal, einer Signalverarbeitungseinheit zur Verarbeitung des elektrischen Signals, einem Hörer zur Wandlung des elektrischen Signals in ein akustisches Signal und mit einer Antennenspule zur drahtlosen Datenübertragung zwischen dem Hörhilfegerät und einem weiteren Gerät dadurch gelöst, dass die Antennenspule auf den Hörer gewickelt ist.This object is achieved in a hearing aid with at least one Microphone for recording an acoustic input signal and conversion to an electrical signal, a signal processing unit for processing the electrical signal, a receiver for converting the electrical signal into an acoustic one Signal and with an antenna coil for wireless Data transmission between the hearing aid and another Device solved by the antenna coil on the listener is wound.

Die Erfindung bietet den Vorteil, dass durch die auf den Hörer gewickelte Antennenspule kaum zusätzlicher Platz im Hörhilfegerät benötigt wird. Ein weiterer Vorteil der Erfindung liegt darin, dass das von dem Hörer auf die Antennenspule übertragene elektromagnetische Signal zumeist ein sehr gut definiertes von der Antennenspule aufgenommenes Störsignal ist. Bei einer auf den Hörer gewickelten Antennenspule kann das Signalübertragungsverhalten zwischen dem Hörer und der Antennenspule exakt erfasst werden, was eine gute Kompensation des von dem Hörer übertragenen Signals ermöglicht.The invention offers the advantage that by the on the listener wound antenna coil barely extra space in the hearing aid is needed. Another advantage of the invention is that the transmitted from the listener to the antenna coil electromagnetic signal is usually a very well defined one is received by the antenna coil noise signal.

Zur Kompensation des von dem Hörer erzeugten elektromagnetischen Feldes sieht eine Ausführungsform der Erfindung eine Kompensationsspule vor. Durch die Kompensationsspule wird ein elektromagnetisches Feld erzeugt, das dem von dem Hörer im Bereich der Antennenspule erzeugten elektromagnetischen Feld entgegengerichtet ist und dieses kompensiert. Vorteilhaft ist die Kompensationsspule mit auf den Hörer bzw. das Abschirmblech oder die Abschirmkapsel gewickelt. Dadurch erfordert auch die Kompensationsspule kaum zusätzlichen Platzbedarf im Hörhilfegerät. Die Kompensationsspule kann jedoch auch nicht auf den Hörer gewickelt, sondern beispielsweise vor dem Hörer angeordnet werden. Ist die Kompensationsspule auf den Hörer gewickelt, so kann sie sich auch über oder unter der Antennenspule befinden. To compensate for the electromagnetic generated by the listener Feldes sees an embodiment of the invention a Compensation coil before. Through the compensation coil is a generates an electromagnetic field similar to that of the listener in the Area of the antenna coil generated electromagnetic field is opposite and compensates for this. Is advantageous the compensation coil with on the handset or the shielding or the shielding capsule wound. This requires Also, the compensation coil hardly any additional space in the Hearing aid. However, the compensation coil can not wrapped on the receiver, but for example in front of the listener to be ordered. Is the compensation coil on the handset wrapped so it can also be above or below the antenna coil are located.

Bei einer Variante der Erfindung sind die Antennenspule und die Kompensationsspule als Spule mit Mittelabgriff ausgeführt. Dies vereinfacht und verbilligt die Herstellung des Hörhilfegerätes gemäß der Erfindung.In a variant of the invention, the antenna coil and the compensation coil designed as a coil with center tap.

Eine weitere Ausführungsform der Erfindung sieht eine elektrische Kompensationsschaltung, die sowohl als externer Schaltkreis als auch als in einen Hörhilfegeräte-IC integrierter Schaltkreis ausgeführt sein kann, in Verbindung mit der Kompensationsspule zur Kompensation des von dem Hörer auf die Antennenspule übertragenen elektromagnetischen Signals vor. Vorzugsweise ist der Kompensationsschaltung direkt das elektrische Hörer-Eingangssignal zugeführt. Dieses wird in der Kompensationsschaltung nach Amplitude und/oder Phase modifiziert und in die Kompensationsspule eingespeist. Dies trägt zu einer besonders effektiven Kompensation des von dem Hörer hervorgerufenen Störsignals bei.Another embodiment of the invention provides an electrical Compensation circuit, both as external Circuit as well as in a hearing aid IC integrated Circuit may be designed in conjunction with the compensation coil for compensation of the on the listener the antenna coil transmitted electromagnetic signal in front. Preferably, the compensation circuit is directly the supplied electrical receiver input signal. This will be in the compensation circuit according to amplitude and / or phase modified and fed to the compensation coil. This contributes to a particularly effective compensation of the Listener caused interference signal.

Die Kompensationsschaltung kann als aktives oder passives Filter ausgeführt sein. Weiterhin können die Filterparameter dieser Kompensationsschaltung entweder statisch gewählt oder adaptiv während des Betriebes angepasst werden.The compensation circuit can be active or passive Be executed filter. Furthermore, the filter parameters this compensation circuit either statically selected or adapted adaptively during operation.

Während sich die oben beschriebene Kompensation auf die weitgehende Auslöschung des von dem Hörer hervorgerufenen, ungewollten Magnetfeldes innerhalb der Antennenspule bezieht, kann diese Kompensation bei einer weiteren Ausführungsform der Erfindung auch elektrisch durch eine entsprechende Signalverarbeitung in dem Hörhilfegerät, vor Abgabe der Hörersignale, durchgeführt werden. Hierzu umfasst das Hörhilfegerät vorzugsweise ein Subtraktionsfilter, in dem das Hörer-Eingangssignal verarbeitet und von dem vorliegenden elektrischen Antennensignal abgezogen wird. Durch dieses interne Kompensationsverfahren mittels elektronischer Signalverarbeitung wird eine Kompensation durchgeführt, die das Magnetfeld des Hörers nicht beeinflusst. Diese Art der Kompensation stellt daher auch eine sehr energieeffiziente Lösung dar. While the compensation described above applies to the broadest Extinguishing the unwanted, caused by the listener Magnetic field inside the antenna coil, can this compensation in a further embodiment the invention also electrically by a corresponding signal processing in the hearing aid, before delivery of the receiver signals, be performed. This includes the hearing aid preferably a subtraction filter in which the handset input signal processed and from the present electrical Antenna signal is subtracted. By this internal Compensation method by means of electronic signal processing a compensation is performed, which is the magnetic field not influenced by the listener. This kind of compensation therefore also represents a very energy-efficient solution.

Weiterhin kann das Hörhilfegerät gemäß der Erfindung auch Teil eines mehrere Geräte zur Versorgung eines Schwerhörigen umfassenden Hörgerätesystems sein, z.B. Teil eines Hörgerätesystems mit zwei am Kopf getragenen Hörgeräten zur binauralen Versorgung oder Teil eines Hörgerätesystem, bestehend aus einem am Kopf tragbaren Gerät und einer am Körper tragbaren Prozessoreinheit.The invention can be used in all known hearing aid types be applied, for example, behind the ear portable Hearing aids, in the ear portable hearing aids, implantable Hearing aids or pocket hearing aids.

In this case, the compensation circuit is advantageous as active or passive filter executed.

    Weiterhin umfasst das Hörhilfegerät gemäß Figur 2 einen Hörer 14A, auf den gemäß der Erfindung eine Antennenspule 14B gewickelt ist. Die Antennenspule 14B steht in Verbindung mit der Signalverarbeitungs- und Steuereinheit 12 des Hörhilfegerätes, so dass mittels der Antennenspule 14B ein elektromagnetisches Signal empfangen und in dem Hörhilfegerät weiter verarbeitet werden kann. Umgekehrt kann ausgehend von der Signalverarbeitungs- und Steuereinheit 12 über die Antennenspule 14B auch ein elektromagnetisches Signal von dem Hörhilfegerät abgegeben werden. Sowohl bei einem empfangenen als auch bei einem abgegebenen Signal kann es sich um ein Audiooder ein Datensignal handeln. Dabei werden unter einem Datensignal solche Signale verstanden, die keine Audioinformation tragen, sondern eine sonstige Information, die beispielsweise zur Programmierung oder Steuerung des Hörhilfegerätes dient.Furthermore, the hearing aid according to Figure 2 comprises a handset 14A, on which according to the invention an antenna coil 14B is wound is. The antenna coil 14B is in communication with the Signal processing and control unit 12 of the hearing aid, so that by means of the antenna coil 14B an electromagnetic Receive signal and continue in the hearing aid can be processed. Conversely, starting from the Signal processing and control unit 12 via the antenna coil 14B also an electromagnetic signal from the hearing aid be delivered. Both at a received as even with a given signal, it may be an audio or act a data signal. It will be under a data signal such signals understood that no audio information but other information, for example for programming or controlling the hearing aid is used.

    Das Hörhilfegerät gemäß Figur 2 umfasst weiterhin ein Stellglied 15, z.B. einen Lautstärkesteller, durch den die Signalverarbeitung in der Signalverarbeitungs- und Steuereinheit 12 beeinflusst werden kann. Schließlich ist in dem Hörhilfegerät eine Batterie 16 zur Spannungsversorgung der einzelnen Komponenten des Hörhilfegerätes vorhanden.The hearing aid according to FIG. 2 further comprises an actuator 15, e.g. a volume control, through which the signal processing in the signal processing and control unit 12 can be influenced. Finally, in the hearing aid a battery 16 for powering the individual components the hearing aid available.

    Ein weiteres Ausführungsbeispiel der Erfindung zeigt Figur 3. Ähnlich dem in Figur 2 dargestellten Hörhilfegerät umfasst auch dieses ein Mikrofon 20 zur Aufnahme eines akustischen Eingangssignals und Wandlung in ein elektrisches Signal, eine Signalvorverarbeitungseinheit 21 zur A/D-Wandlung und Vorverstärkung des Eingangssignals, eine Signalverarbeitungs- und Steuereinheit 22 zur Verarbeitung und frequenzabhängigen Verstärkung des elektrischen Signals, einen Hörer 24A, auf den gemäß der Erfindung eine Antennenspule 24B gewickelt ist, einen Lautstärkesteller 25 sowie eine Batterie 26 zur Spannungsversorgung der Komponenten des Hörhilfegerätes.A further embodiment of the invention is shown in FIG. 3. Similar to the hearing aid device shown in FIG also this a microphone 20 for receiving an acoustic Input signal and conversion into an electrical signal, a Signal preprocessing unit 21 for A / D conversion and pre-amplification of the input signal, a signal processing and Control unit 22 for processing and frequency-dependent amplification of the electrical signal, a handset 24A, on the According to the invention, an antenna coil 24B is wound, a Volume control 25 and a battery 26 for power supply the components of the hearing aid.

    Anders als bei dem Ausführungsbeispiel gemäß Figur 2, bei dem mittels einer Kompensationseinheit 13 und insbesondere einer Kompensationsspule 13A ein Überkoppeln eines von dem Hörer 14A erzeugten elektromagnetischen Signals auf die Antennenspule 14B verhindert wird, sieht das Ausführungsbeispiel gemäß Figur 3 eine elektronische Kompensation eines von dem Hörer 24A auf die Antennenspule 24B übertragenen Störsignals vor. Hierzu umfasst die Kompensationseinheit 23 insbesondere ein Subtraktionsfilter 23A sowie weitere Filtermittel 23B. Der Kompensationseinheit 23 ist sowohl das dem Hörer 24A zugeführte elektrische Signal als auch das von der Antennenspule 24B abgegebene elektrische Signal zugeführt. Unlike the embodiment of Figure 2, in which by means of a compensation unit 13 and in particular a Compensation coil 13A overcoupling one of the listener 14A generated electromagnetic signal on the antenna coil 14B is prevented, the embodiment according to FIG Figure 3 is an electronic compensation of one of the listener 24A, the interference signal transmitted to the antenna coil 24B in front. For this purpose, the compensation unit 23 comprises in particular a subtraction filter 23A and other filter means 23B. The compensation unit 23 is both the one supplied to the handset 24A electrical signal as well as that of the antenna coil 24B supplied electrical signal.

    Da die Antennenspule 24B auf den Hörer 24A gewickelt ist, ist auch das Signalübertragungsverhalten von dem Hörer 24A auf die Antennenspule 24B exakt determinierbar. Dadurch lassen sich Parameter der Kompensationseinheit 23 so einstellen, dass die von dem Hörer 24A herrührenden Signalanteile in dem Ausgangssignal der Antennenspule 24B exakt bestimmt und von dem Ausgangssignal subtrahiert werden können. Der Signalverarbeitungs- und Steuereinheit 22 werden somit lediglich die von einer Signalquelle außerhalb des Hörhilfegerätes herrührenden Signalanteile des Ausgangssignals der Antennenspule 24B zugeführt.Since the antenna coil 24B is wound on the receiver 24A also the signal transmission behavior of the handset 24A the antenna coil 24B can be determined exactly. Leave it set parameters of the compensation unit 23 so in that the signal components originating from the handset 24A in the Output signal of the antenna coil 24B exactly determined and from can be subtracted from the output signal. The signal processing and control unit 22 are thus only the originating from a signal source outside the hearing aid Signal components of the output signal of the antenna coil 24B supplied.

    Wie bei dem Ausführungsbeispiel gemäß Figur 2 sind auch die Parameter, insbesondere Filterparameter, der Kompensationseinheit 23 einstellbar, beispielsweise während der Programmierung des Hörhilfegerätes. Vorzugsweise können jedoch auch diese Parameter adaptiv während des Betriebes des Hörhilfegerätes angepasst werden.As in the embodiment of Figure 2 are also the Parameters, in particular filter parameters, of the compensation unit 23 adjustable, for example during programming the hearing aid. However, preferably These parameters also adaptively during operation of the hearing aid be adjusted.

    Durch das elektronische Kompensationsverfahren wird eine Kompensation durchgeführt, die das Magnetfeld des Hörers nicht beeinflusst. Weiterhin stellt diese Art der Kompensation auch eine sehr energieeffiziente Lösung dar.The electronic compensation method is compensated performed the magnetic field of the listener is not affected. Furthermore, this type of compensation also provides a very energy efficient solution.

    Zusammenfassend wird festgehalten:In summary, it is stated:

    Zur drahtlosen Signalübertragung zwischen einem Hörhilfegerät und einem weiteren Gerät ist in dem Hörhilfegerät eine Antennenspule vorhanden. Aufgrund der geforderten Miniaturisierung bei Hörhilfegeräten steht für die Anordnung der Antennenspule im Hörhilfegerät nur wenig Platz zur Verfügung. Die Erfindung schlägt deshalb vor, die Antennenspule auf einen in dem Hörhilfegerät vorhandenen elektroakustischen Wandler bzw. eine den Wandler umgebende Kapsel zu wickeln. Dadurch kann eine verhältnismäßig große Antennenspule in dem Hörhilfegerät bereitgestellt werden, für die kaum zusätzlicher Platz beansprucht wird.For wireless signal transmission between a hearing aid and another device is in the hearing aid, an antenna coil available. Due to the required miniaturization Hearing aid stands for the arrangement of the antenna coil in the hearing aid only little space available.
