- IDO in-the-ear hearing aids
- Concha hearing aids are provided.
- the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
- bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
- Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
- the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
- the output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized.
- the amplifier is usually integrated in a signal processing unit. This basic structure is in FIG. 1 shown using the example of a behind-the-ear hearing aid. In a hearing aid housing 1 for carrying behind the ear, one or more microphones 2 for receiving the sound from the environment are installed.
- a signal processing unit 3 which is also integrated into the hearing aid housing 1, processes the microphone signals and amplifies them.
- the output signal of the signal processing unit 3 is transmitted to a loudspeaker or earpiece 4, which outputs an acoustic signal.
- the sound is optionally transmitted via a sound tube, which is fixed with an earmold in the ear canal, to the eardrum of the device carrier.
- the power supply of the hearing device and in particular of the signal processing unit 3 is carried out by a likewise integrated into the hearing aid housing 1 battery. 5
- the respective user When wearing hearing aids and other hearing devices, the respective user may be in different listening situations. For example, he may be in the listening situation “quiet environment”, “noise environment”, “concert hall”, “telephoning”, etc.
- the recognition of the hearing situation “telephoning” is particularly desirable because it occurs relatively frequently and here the hearing aid should be set fundamentally different compared to standard listening situations. In most cases, an inductive input signal can be used while telephoning and acoustically incoming ambient noise can be greatly attenuated.

- a wireless programmable hearing aid has a transponder with which it can receive programming signals from a programming device wirelessly and send back certain response signals.
- the transponder has an electric coil for this purpose.
- the object of the present invention is therefore to be able to carry out the automatic control of a hearing device from a more reliable external.
- this object is achieved by a hearing device with a signal processing device for processing an input signal to an acoustically reproducible output signal, and a transponder detection device for detecting a transponder and providing a corresponding detection signal, wherein the processing is performed by the signal processing device in response to the detection signal.
- a hearing system is also provided with such a hearing device and a device external to the hearing device that is physically connected to a transponder.
- the invention provides a method for controlling a hearing device by processing an input signal to an acoustically reproducible output signal, and detecting a transponder and providing a corresponding detection signal, wherein the processing is controlled in dependence on the detection signal.
- the controlling of the hearing device and in particular of the hearing device can thus take place in a reliable manner by a transponder (tag), which is brought to the hearing device.
- a transponder tag
- the hearing device On the part of the hearing device, this requires no additional mechanical or electrical components, if the hearing device already has an electromagnetic transmission system. In particular, it is thus possible to dispense with reed contacts, GMR sensors, etc. for detecting the telephone situation. Thus, the hearing devices or hearing aids can be made smaller.
- the reliability of the detection is increased according to the invention, since the magnetic field coupling over an extended coil in the transponder is better than that via a reed contact and a permanent magnet.

- the transponder detection device of the hearing device is able to detect a transponder based on an energy loss.
- the oscillation amplitude of a resonant circuit can be checked with very little effort. It is advantageous if the transponder detection device cyclically analyzes its own transmission energy for detecting the transponder.
- the transponder detection device may also be able to detect a transponder based on a frequency change.
- a defined detuning of the frequency of a resonant circuit can be a clear indication of the presence of a transponder.
- the transponder detection device may be able to detect a transponder based on an impulse response. It can be advantageously exploited that a transponder can answer a transmission pulse in a characteristic way.
- the transponder detection device uses several frequencies for detecting. It can be provided, for example, that a predetermined frequency range is scanned by the transponder detection device.
- the frequencies can be changed, for example, by wobbling or by switching, which can be realized very easily.
- the transponder On the part of the transponder, it is particularly favorable if the transponder consists exclusively of an LC resonant circuit. Such a transponder can be produced cheaply and in a very small design.
- a hearing aid 10 has a so-called wireless system 11 with which it is able to establish a wireless connection to an external device.
- an LC oscillation circuit having a capacitor C1 and a coil L1 is used.
- the resonant circuit is driven or driven by a driver V1.
- an alternating magnetic field 12 is constructed.
- the hearing aid should now recognize that a telephone or other device has been brought near it in order to switch to the corresponding hearing aid program, here a telephone program.
- a remote control of a TV or a radio placed in the vicinity of the hearing aid to switch accordingly into a televisions hearing aid program or radio hearing aid program.
- the hearing aid 10 itself can be brought into the vicinity of the respective external device.
- a transponder is attached to it.
- the transponder 13 is attached to a telephone 14.
- a coil L2 together with a capacitor C2 forms a resonant circuit of the transponder 13.
- Both components L2, C2 form a simple RFID transponder.
- An RFID transponder for example, from the publication DE 20 2006 006 921 U1 known.
- the acting as an antenna coil L2 of the transponder 13 is in interaction with the magnetic field 12.
- the energy demand of the wireless system 11 of the hearing aid is thus influenced in operation by the presence of the transponder 13 and its resonant circuit L2, C2. This principle is known from RFID technology.
- the coil L2 and the capacitor C2 should be made very flat.
- the area covered by the coil L2 is in principle freely selectable. However, the area is important for the recognition rate, because the field enforcement of the receiving coil L2 determines the induced voltage.
- the approach of the transponder 13 is determined by cyclically polling the transmission energy in the hearing aid 10.
- a voltage is tapped off at the transmitter oscillation circuit L1, C1, amplified by an amplifier V2 and made available as a detection signal 15 for the hearing aid signal processing.
- the hearing aid 10 actively seeks the transponder 13 here.
- the frequencies with which the hearing aid 10 searches the transponder 13 are varied within a small range in order to intercept manufacturing tolerances of the transponder 13.
- the frequencies can be changed by wobbling continuously or by switching abruptly.
- the security of the telephone recognition can be increased with binaural supply of a hearing aid wearer, if the two hearing aids are coupled to each other wirelessly or by wire.
- the telephone recognition preferably only responds if the transmission energy at one side is increased at the resonance frequency and not at the other side.

Description
Die vorliegende Erfindung betrifft eine Hörvorrichtung mit einer Signalverarbeitungseinrichtung zum Verarbeiten eines Eingangssignals zu einem akustisch wiederzugebenden Ausgangssignal. Darüber hinaus betrifft die vorliegende Erfindung ein Verfahren zum Steuern einer Hörvorrichtung. Unter dem Begriff Hörvorrichtung wird hier insbesondere ein Hörgerät, aber auch ein Headset, Kopfhörer etc. verstanden.The present invention relates to a hearing device with a signal processing device for processing an input signal to an acoustically reproducible output signal. Moreover, the present invention relates to a method for controlling a hearing device. The term hearing device is understood to mean in particular a hearing aid, but also a headset, headphones, etc.
Hörgeräte sind tragbare Hörvorrichtungen, die zur Versorgung von Schwerhörenden dienen. Um den zahlreichen individuellen Bedürfnissen entgegenzukommen, werden unterschiedliche Bauformen von Hörgeräten wie Hinter-dem-Ohr-Hörgeräte (HdO), Indem-Ohr-Hörgeräte (IdO) und Concha-Hörgeräte bereitgestellt. Die beispielhaft aufgeführten Hörgeräte werden am Außenohr oder im Gehörgang getragen. Darüber hinaus stehen auf dem Markt aber auch Knochenleitungshörhilfen, implantierbare oder vibrotaktile Hörhilfen zur Verfügung. Dabei erfolgt die Stimulation des geschädigten Gehörs entweder mechanisch oder elektrisch.Hearing aids are portable hearing aids that are used to care for the hearing impaired. To meet the numerous individual needs, different types of hearing aids such as behind-the-ear hearing aids (BTE), in-the-ear hearing aids (IDO) and Concha hearing aids are provided. The hearing aids listed by way of example are worn on the outer ear or in the ear canal. In addition, bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
Hörgeräte besitzen prinzipiell als wesentliche Komponenten einen Eingangswandler, einen Verstärker und einen Ausgangswandler. Der Eingangswandler ist in der Regel ein Schallempfänger, z. B. ein Mikrofon, und/oder ein elektromagnetischer Empfänger, z. B. eine Induktionsspule. Der Ausgangswandler ist meist als elektroakustischer Wandler, z. B. Miniaturlautsprecher, oder als elektromechanischer Wandler, z. B. Knochenleitungshörer, realisiert. Der Verstärker ist üblicherweise in eine Signalverarbeitungseinheit integriert. Dieser prinzipielle Aufbau ist in
Beim Tragen von Hörgeräten und anderen Hörvorrichtungen kann sich der jeweilige Nutzer in unterschiedlichen Hörsituationen befinden. Beispielsweise kann er sich in der Hörsituation "ruhige Umgebung", "Umgebung mit Störgeräuschen", "Konzertsaal", "Telefonieren" etc. befinden. Die Erkennung der Hörsituation "Telefonieren" ist besonders wünschenswert, da sie verhältnismäßig häufig auftritt und hier das Hörgerät im Vergleich zu Standard-Hörsituationen grundlegend anders eingestellt werden sollte. Meist kann nämlich beim Telefonieren ein induktives Eingangssignal genutzt und akustisch eingehende Umgebungsgeräusche stark gedämpft werden. Für den Nutzer ist es besonders vorteilhaft, wenn die Hörsituation "Telefonieren" automatisch vom Hörgerät oder der jeweiligen Hörvorrichtung erkannt wird, so dass ein Telefonat von Anfang an zufriedenstellend geführt werden kann.When wearing hearing aids and other hearing devices, the respective user may be in different listening situations. For example, he may be in the listening situation "quiet environment", "noise environment", "concert hall", "telephoning", etc. The recognition of the hearing situation "telephoning" is particularly desirable because it occurs relatively frequently and here the hearing aid should be set fundamentally different compared to standard listening situations. In most cases, an inductive input signal can be used while telephoning and acoustically incoming ambient noise can be greatly attenuated. For the user, it is particularly advantageous if the hearing situation "telephoning" is automatically detected by the hearing device or the respective hearing device, so that a telephone call can be performed satisfactorily from the beginning.
Zum automatischen Erkennen der Hörsituation "Telefonieren" wird heute vielfach ein Magnet auf das Telefon aufgeklebt, das beim Heranführen des Telefons an das Hörgerät einen Reed-Kontakt im Hörgerät betätigt. Die Positionierung des Magneten zum Reed-Kontakt ist kritisch. Außerdem ist die Nähe des starken magnetischen Feldes schädlich für den Hörgeräte-Hörer. Ein starkes magnetisches Feld kann nämlich nicht nur zu vorübergehenden Störungen, sondern auch zur Zerstörung des Hörers bzw. Lautsprechers führen. Darüber hinaus kann der Reed-Kontakt auch leicht von anderen, nicht am Telefon angebrachten Magneten ausgelöst werden und somit eine falsche Steuerung bzw. Programmwahl verursachen.For automatic recognition of the hearing situation "telephoning" a magnet is now often glued to the phone, which operates a reed contact in the hearing aid when the phone is brought to the hearing aid. The positioning of the magnet for reed contact is critical. In addition, the proximity of the strong magnetic field is detrimental to the hearing device handset. In fact, a strong magnetic field can not only lead to temporary disturbances, but also to the destruction of the listener or loudspeaker.

Aus der Druckschrift
Die Aufgabe der vorliegenden Erfindung besteht somit darin, das automatische Steuern einer Hörvorrichtung von extern zuverlässiger durchführen zu können.The object of the present invention is therefore to be able to carry out the automatic control of a hearing device from a more reliable external.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine Hörvorrichtung mit einer Signalverarbeitungseinrichtung zum Verarbeiten eines Eingangssignals zu einem akustisch wiederzugebenden Ausgangssignal, und einer Transponderdetektionseinrichtung zum Detektieren eines Transponders und Bereitstellen eines entsprechenden Detektionssignals, wobei die Verarbeitung durch die Signalverarbeitungseinrichtung in Abhängigkeit von dem Detektionssignal erfolgt.According to the invention, this object is achieved by a hearing device with a signal processing device for processing an input signal to an acoustically reproducible output signal, and a transponder detection device for detecting a transponder and providing a corresponding detection signal, wherein the processing is performed by the signal processing device in response to the detection signal.
Dementsprechend wird auch bereitgestellt ein Hörsystem mit einer derartigen Hörvorrichtung und einem bezüglich der Hörvorrichtung externen Gerät, das mit einem Transponder körperlich verbunden ist.Accordingly, a hearing system is also provided with such a hearing device and a device external to the hearing device that is physically connected to a transponder.
Weiterhin wird erfindungsgemäß bereitgestellt ein Verfahren zum Steuern einer Hörvorrichtung durch Verarbeiten eines Eingangssignals zu einem akustisch wiederzugebenden Ausgangssignal, und Detektieren eines Transponders sowie Bereitstellen eines entsprechenden Detektionssignals, wobei das Verarbeiten in Abhängigkeit von dem Detektionssignal gesteuert wird.Furthermore, the invention provides a method for controlling a hearing device by processing an input signal to an acoustically reproducible output signal, and detecting a transponder and providing a corresponding detection signal, wherein the processing is controlled in dependence on the detection signal.
Das Steuern der Hörvorrichtung und insbesondere des Hörgeräts kann somit auf zuverlässige Weise durch einen Transponder (Tag) erfolgen, der an die Hörvorrichtung herangeführt wird.The controlling of the hearing device and in particular of the hearing device can thus take place in a reliable manner by a transponder (tag), which is brought to the hearing device.
Seitens der Hörvorrichtung erfordert dies keine zusätzlichen mechanischen oder elektrischen Bauteile, wenn die Hörvorrichtung bereits über ein elektromagnetisches Übertragungssystem verfügt. Insbesondere kann also zur Erkennung der Telefonsituation auf Reed-Kontakte, GMR-Sensoren etc. verzichtet werden. Somit können die Hörvorrichtungen bzw. Hörgeräte kleiner gebaut werden. Außerdem wird erfindungsgemäß die Zuverlässigkeit der Detektion erhöht, da die magnetische Feldkopplung über eine ausgedehnte Spule im Transponder besser ist als die über einen Reed-Kontakt und einen Permanentmagneten. Der Transponder ist außerdem magnetisch völlig inaktiv, d. h. er kann weder den Hörer noch andere empfindliche Bauteile stören. Der Transport in sensitiver Umgebung (z. B. im Flugzeug) ist dadurch wesentlich unproblematischer.On the part of the hearing device, this requires no additional mechanical or electrical components, if the hearing device already has an electromagnetic transmission system. In particular, it is thus possible to dispense with reed contacts, GMR sensors, etc. for detecting the telephone situation. Thus, the hearing devices or hearing aids can be made smaller. In addition, the reliability of the detection is increased according to the invention, since the magnetic field coupling over an extended coil in the transponder is better than that via a reed contact and a permanent magnet. The transponder is also magnetically completely inactive, d. H. he can not disturb the receiver or other sensitive components. The transport in a sensitive environment (eg in the aircraft) is thus much less problematic.
Vorzugsweise ist die Transponderdetektionseinrichtung der Hörvorrichtung in der Lage, anhand eines Energieverlusts einen Transponder zu detektieren. So kann beispielsweise mit sehr geringem Aufwand die Schwingungsamplitude eines Resonanzkreises überprüft werden. Dabei ist es günstig, wenn die Transponderdetektionseinrichtung zyklisch die eigene Sendeenergie zum Detektieren des Transponders analysiert.Preferably, the transponder detection device of the hearing device is able to detect a transponder based on an energy loss. Thus, for example, the oscillation amplitude of a resonant circuit can be checked with very little effort. It is advantageous if the transponder detection device cyclically analyzes its own transmission energy for detecting the transponder.
Die Transponderdetektionseinrichtung kann außerdem in der Lage sein, anhand einer Frequenzänderung einen Transponder zu detektieren. So kann beispielsweise eine definierte Verstimmung der Frequenz eines Schwingkreises ein eindeutiges Zeichen für die Anwesenheit eines Transponders sein.The transponder detection device may also be able to detect a transponder based on a frequency change. For example, a defined detuning of the frequency of a resonant circuit can be a clear indication of the presence of a transponder.
Des Weiteren kann die Transponderdetektionseinrichtung in der Lage sein, anhand einer Impulsantwort einen Transponder zu detektieren. Dabei kann vorteilhaft ausgenützt werden, dass ein Transponder einen Sendeimpuls auf charakteristische Weise beantworten kann.Furthermore, the transponder detection device may be able to detect a transponder based on an impulse response. It can be advantageously exploited that a transponder can answer a transmission pulse in a characteristic way.
Entsprechend einer weiteren bevorzugten Ausführungsform nutzt die Transponderdetektionseinrichtung zum Detektieren mehrere Frequenzen. Dabei kann beispielsweise vorgesehen sein, dass von der Transponderdetektionseinrichtung ein vorgegebener Frequenzbereich gescannt wird. Hierzu können die Frequenzen beispielsweise durch Wobbeln oder durch Schalten verändert werden, was sich sehr einfach realisieren lässt.According to a further preferred embodiment, the transponder detection device uses several frequencies for detecting. It can be provided, for example, that a predetermined frequency range is scanned by the transponder detection device. For this purpose, the frequencies can be changed, for example, by wobbling or by switching, which can be realized very easily.
Seitens des Transponders ist es besonders günstig, wenn der Transponder ausschließlich aus einem LC-Schwingkreis besteht. Ein derartiger Transponder lässt sich günstig und in sehr kleiner Bauform herstellen.On the part of the transponder, it is particularly favorable if the transponder consists exclusively of an LC resonant circuit. Such a transponder can be produced cheaply and in a very small design.

Entsprechend dem Beispiel von
Das Hörgerät soll nun erkennen, dass ein Telefon oder ein anderes Gerät in seine Nähe gebracht wurde, um in das entsprechende Hörgeräteprogramm, hier ein Telefonprogramm, zu schalten. Beispielsweise kann auch eine Fernbedienung eines Fernsehapparats oder eines Radios in die Nähe des Hörgeräts gebracht werden, um entsprechend in ein Fernsehhörgeräteprogramm oder Radiohörgeräteprogramm zu schalten. Selbstverständlich kann auch das Hörgerät 10 selbst in die Nähe des jeweiligen externen Geräts gebracht werden.The hearing aid should now recognize that a telephone or other device has been brought near it in order to switch to the corresponding hearing aid program, here a telephone program. For example, a remote control of a TV or a radio placed in the vicinity of the hearing aid to switch accordingly into a televisions hearing aid program or radio hearing aid program. Of course, the
Damit das Hörgerät 10 das externe Gerät (Telefon, Fernbedienung, etc.) erkennt, ist an dieses ein Transponder angebracht. Im Beispiel von
Eine Spule L2 bildet zusammen mit einem Kondensator C2 einen Schwingkreis des Transponders 13. Beide Bauteile L2, C2 bilden einen einfachen RFID-Transponder. Ein RFID-Transponder ist beispielsweise auch aus der Druckschrift
Die als Antenne wirkende Spule L2 des Transponders 13 steht in Wechselwirkung mit dem Magnetfeld 12. Der Energiebedarf des Wirless-Systems 11 des Hörgeräts wird somit im Betrieb von der Gegenwart des Transponders 13 bzw. seines Schwingkreises L2, C2 beeinflusst. Dieses Prinzip ist aus der RFID-Technik bekannt.The acting as an antenna coil L2 of the
Da der Schwingkreis-Transponder 13 auf den Telefonhörer bzw. das Telefon 14 oder das entsprechend andere externe Gerät aufgebracht wird, sollten die Spule L2 und der Kondensator C2 sehr flach ausgeführt sein. Dabei ist die von der Spule L2 umfasste Fläche prinzipiell frei wählbar. Die Fläche ist jedoch für die Erkennungsrate wichtig, denn die Felddurchsetzung der Empfangsspule L2 bestimmt die induzierte Spannung.Since the
Die Annäherung des Transponders 13 wird durch zyklische Abfrage der Sendeenergie im Hörgerät 10 ermittelt. Gemäß dem Beispiel von
Die Frequenzen, mit denen das Hörgerät 10 den Transponder 13 sucht, werden in einem kleinen Bereich variiert, um Fertigungstoleranzen des Transponders 13 abzufangen. Dabei können die Frequenzen durch Wobbeln kontinuierlich oder durch Schalten sprunghaft verändert werden.The frequencies with which the
Die Sicherheit der Telefonerkennung kann bei binauraler Versorgung eines Hörgeräteträgers erhöht werden, wenn die beiden Hörgeräte miteinander drahtlos oder drahtgebunden gekoppelt sind. In diesem Fall spricht die Telefonerkennung vorzugsweise nur dann an, wenn auf einer Seite die Sendeenergie bei der Resonanzfrequenz erhöht ist und auf der anderen Seite nicht.The security of the telephone recognition can be increased with binaural supply of a hearing aid wearer, if the two hearing aids are coupled to each other wirelessly or by wire. In this case, the telephone recognition preferably only responds if the transmission energy at one side is increased at the resonance frequency and not at the other side.
