Description

Die vorliegende Erfindung betrifft ein Hörsystem mit einer ersten Hörvorrichtung zum Tragen im/am Ohr und einer zweiten Hörvorrichtung ebenfalls zum Tragen im/am Ohr. Insbesondere betrifft die vorliegende Erfindung ein binaurales Hörgerätesystem. Die Erfindung kann aber auch auf andere Hörvorrichtungen wie Headsets, Kopfhörer und dergleichen angewandt werden.The present invention relates to a hearing system with a first hearing device for wearing in / on the ear and a second hearing device also for wearing in / on the ear. In particular, the present invention relates to a binaural hearing aid system. However, the invention can also be applied to other hearing devices such as headsets, headphones and the like.

Zum Ein- und Ausschalten von Hörgeräten wird häufig ein Batteriefachschalter verwendet. Das Batteriefach lässt sich bis zu einer Rastposition öffnen und unterbricht dadurch den Stromkreis. Solche Batteriefächer sind relativ fehleranfällig und benötigen viel Platz im Hörgeräte-Gehäuse. Außerdem ist ein wasserdichter Anschluss nur sehr schwierig zu realisieren.A battery switch is often used to turn hearing aids on and off. The battery compartment can be opened up to a locking position and thus interrupts the circuit. Such battery compartments are relatively error-prone and require a lot of space in the hearing aid housing. In addition, a watertight connection is very difficult to realize.

Neben diesen Batteriefachschaltern werden natürlich auch Standard-Schalter und -Taster zum Ein- und Ausschalten der Hörgeräte verwendet. Diese Standard-Schalteinrichtungen haben jedoch den Nachteil eines großen Platzbedarfs im Hörgeräte-Gehäuse.In addition to these battery-operated switches, of course, standard switches and buttons are also used to turn the hearing aids on and off. However, these standard switching devices have the disadvantage of a large footprint in the hearing aid housing.

Die Druckschrift DE 7011139U beschreibt ein Hörgerät mit einem in dem Hörgeräte-Gehäuse angeordneten Zungenrelaisschalter. Dieser Zungenrelaisschalter ist durch einen außerhalb des Gehäuses angeordneten Magneten schaltbar. Beispielsweise kann das Hörgerät in einem Behälter bei Nichtgebrauch aufbewahrt werden. Das Behältnis enthält eine Spule oder einen Permanentmagneten, durch die bzw. den der Zungenrelaisschalter geöffnet wird, wenn das Hörgerät in das Behältnis gegeben wird. Nachteilig dabei ist jedoch, dass zum Abschalten des Hörgeräts das Behältnis zur Hand sein muss, wenn kein anderer Schalter vorgesehen ist.The publication DE 7011139U describes a hearing aid with a tongue relay switch located in the hearing aid housing. This tongue relay switch is switchable by a magnet arranged outside the housing. For example, the hearing aid can be stored in a container when not in use. The container contains a coil or a permanent magnet through which the tongue relay switch is opened when the hearing aid is placed in the container. The disadvantage here is that to turn off the hearing aid, the container must be at hand, if no other switch is provided.

Die Aufgabe der vorliegenden Erfindung besteht darin, ein Hörsystem vorzuschlagen, das auf einfache Weise steuerbar ist, wobei möglichst wenig Bauraum für die Steuerkomponenten verwendet wird.The object of the present invention is to propose a hearing system that can be controlled in a simple manner, wherein as little installation space as possible is used for the control components.

Erfindungsgemäß wird diese Aufgabe gelöst durch ein Hörsystem mit einer ersten Hörvorrichtung zum Tragen im/am Ohr und einer zweiten Hörvorrichtung zum Tragen im/am Ohr, wobei die erste Hörvorrichtung einen Permanentmagneten und die zweite Hörvorrichtung einen Magnetsensor aufweist, so dass die zweite Hörvorrichtung in vorbestimmter Weise steuerbar ist, wenn sich die erste Hörvorrichtung in räumlicher Nähe der zweiten Hörvorrichtung befindet und der Magnetsensor deswegen das Magnetfeld des Permanentmagneten oder einen entsprechenden magnetischen Fluss detektiert.According to the invention, this object is achieved by a hearing system with a first hearing device for wearing in / on the ear and a second hearing device for wearing in / on the ear, wherein the first hearing device has a permanent magnet and the second hearing device has a magnetic sensor, so that the second hearing device in a predetermined It is controllable manner when the first hearing device is in the spatial vicinity of the second hearing device and the magnetic sensor therefore detects the magnetic field of the permanent magnet or a corresponding magnetic flux.

Darüber hinaus wird entsprechend der vorliegenden Erfindung bereitgestellt ein Verfahren zum Steuern eines Hörsystems, das eine erste und eine zweite Hörvorrichtung aufweist, durch Platzieren der ersten Hörvorrichtung, die einen Permanentmagneten aufweist, in der räumlichen Nähe der zweiten Hörvorrichtung, die einen Magnetsensor besitzt, Detektieren eines Magnetfelds des Permanentmagneten oder eines durch den Permanentmagneten hervorgerufenen magnetischen Flusses und Steuern der zweiten Hörvorrichtung in Abhängigkeit von dem Detektionsergebnis.Moreover, according to the present invention, there is provided a method of controlling a hearing system having first and second hearing devices by placing the first hearing device having a permanent magnet in the vicinity of the second hearing device having a magnetic sensor, detecting a Magnetic field of the permanent magnet or caused by the permanent magnet magnetic flux and controlling the second hearing device in response to the detection result.

Eine oder beide Hörvorrichtungen des erfindungsgemäßen Hörsystems sind somit steuerbar, ohne dass der Nutzer einen mechanischen Schalter betätigen muss. Die Hörvorrichtungen können ferner wasserdicht ausgeführt werden, da die Schwachstelle Schalter bzw. Batteriefach wegfällt. Außerdem kann der Nutzer des Hörsystems ohne weiteres erkennen, dass sich die Hörvorrichtung(en) in einem bestimmten Steuermodus befindet/befinden, wenn sie nahe beisammen platziert sind.One or both hearing devices of the hearing system according to the invention are thus controllable, without the user having to actuate a mechanical switch. The hearing devices can also be made watertight, since the vulnerability switch or battery compartment is eliminated. In addition, the user of the hearing system can readily recognize that the hearing device (s) are in a particular control mode when placed close together.

Vorzugsweise besitzt die zweite Hörvorrichtung ein ferromagnetisches Element zum Zusammenwirken mit dem Permanentmagneten der ersten Hörvorrichtung. Auf diese Weise ziehen sich die beiden Hörvorrichtungen gegenseitig an und bleiben in dem vorbestimmten Steuer- bzw. Schaltzustand.Preferably, the second hearing device has a ferromagnetic element for cooperation with the permanent magnet the first hearing device. In this way, the two hearing devices attract each other and remain in the predetermined control or switching state.

Mit dem Magnetsensor der zweiten Hörvorrichtung kann der magnetische Fluss in dem ferromagnetischen Element der zweiten Hörvorrichtung detektiert werden. Eine derartige Anordnung erweist sich als günstig, denn das ferromagnetische Element bündelt die Magnetfeldlinien des Permanentmagneten der ersten Hörvorrichtung.With the magnetic sensor of the second hearing device, the magnetic flux in the ferromagnetic element of the second hearing device can be detected. Such an arrangement proves to be favorable because the ferromagnetic element concentrates the magnetic field lines of the permanent magnet of the first hearing device.

Auch die zweite Hörvorrichtung kann einen Permanentmagneten und die erste Hörvorrichtung einen Magnetsensor aufweisen, so dass die erste Hörvorrichtung in Abhängigkeit von der Anwesenheit der zweiten Hörvorrichtung steuerbar ist. Damit sind die beiden Hörvorrichtungen symmetrisch aufgebaut und eine gegenseitige Steuerung ist möglich. Bei diesem Aufbau kann die erste Hörvorrichtung ebenfalls ein ferromagnetisches Element zum Zusammenwirken mit dem Permanentmagneten der zweiten Hörvorrichtung aufweisen. Des Weiteren kann der Magnetsensor der ersten Hörvorrichtung ebenso wie der der zweiten Hörvorrichtung so ausgestaltet sein, dass er den magnetischen Fluss in dem ferromagnetischen Element der ersten Hörvorrichtung detektiert.The second hearing device may also have a permanent magnet and the first hearing device may have a magnetic sensor, so that the first hearing device can be controlled as a function of the presence of the second hearing device. Thus, the two hearing devices are symmetrical and mutual control is possible. In this structure, the first hearing device may also have a ferromagnetic element for cooperation with the permanent magnet of the second hearing device. Furthermore, the magnetic sensor of the first hearing device as well as that of the second hearing device can be configured such that it detects the magnetic flux in the ferromagnetic element of the first hearing device.

Bei einer besonders bevorzugten Ausgestaltung weisen die beiden Hörvorrichtungen eine äußere Struktur nach dem Nut-Feder-Prinzip auf und sind somit aneinander steckbar. Hierdurch werden sie zur gegenseitigen Ansteuerung mechanisch miteinander verbunden.In a particularly preferred embodiment, the two hearing devices on an external structure according to the tongue and groove principle and are thus plugged together. As a result, they are mechanically connected to each other for mutual control.

Günstigerweise besitzt der Magnetsensor eine Hall-Sonde, eine Sonde nach dem GMR-Prinzip (Giant Magneto Resistance) oder einen Reed-Kontakt. Auf diese Weise lassen sich robuste und kostengünstige Magnetsensoren realisieren.Conveniently, the magnetic sensor has a Hall probe, a probe according to the GMR principle (Giant Magneto Resistance) or a reed contact. In this way, robust and inexpensive magnetic sensors can be realized.

Vorzugsweise sind die beiden Hörvorrichtungen als Hörgeräte ausgestaltet. Dabei kommt der Nutzen der Erfindung besonders zur Geltung, denn die kleinen Hörgeräte besitzen in der Regel wenig Bauraum für Schalter und es ist zum Ansteuern der Hörgeräte kein weiteres Gerät bzw. keine weitere Einrichtung, insbesondere kein Behältnis, notwendig.Preferably, the two hearing devices are designed as hearing aids. The benefits of the invention are particularly important here to the extent, because the small hearing aids usually have little space for switches and it is to control the hearing no additional device or no other device, especially no container necessary.

Die beiden Hörvorrichtungen können in drahtloser Kommunikationsverbindung stehen, so dass mit einem Signal des Magnetsensors der zweiten Hörvorrichtung auch die erste Hörvorrichtung steuerbar ist. Dies ist insbesondere dann vorteilhaft, wenn beispielsweise bei einem binauralen Hörgerätesystem ohnehin Kommunikationseinrichtungen zur drahtlosen Verbindung in beiden Hörgeräten vorgesehen sind.The two hearing devices can be in wireless communication connection, so that with a signal of the magnetic sensor of the second hearing device, the first hearing device is controllable. This is advantageous in particular if, for example, in the case of a binaural hearing device system, communication devices for wireless connection are already provided in both hearing aids.

Die zweite Hörvorrichtung kann bei Detektion des Permanentmagneten der ersten Hörvorrichtung abgeschaltet werden. Umgekehrt kann auch die erste Hörvorrichtung bei Detektion des Permanentmagneten der zweiten Hörvorrichtung abgeschaltet werden. Dieser Sonderfall der Steuerung weist sich insbesondere hinsichtlich der Energieeinsparung als vorteilhaft aus.The second hearing device can be switched off upon detection of the permanent magnet of the first hearing device. Conversely, the first hearing device can be switched off upon detection of the permanent magnet of the second hearing device. This special case of the controller is advantageous, in particular with regard to energy savings.

Die vorliegende Erfindung wird nun anhand der beigefügten Zeichnung näher erläutert, die ein erfindungsgemäßes binaurales Hörgerätesystem zeigt.The present invention will now be explained in more detail with reference to the accompanying drawing which shows a binaural hearing aid system according to the invention.

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.

Das in der FIG wiedergegebene Hörgerätesystem besteht aus einem ersten Hörgerät 1 und einem zweiten Hörgerät 2. In der Schale 10 des ersten Hörgeräts 1 befindet sich ein Permanentmagnet 11. In der Hörgeräteschale 20 des zweiten Hörgeräts 2 ist ein ferromagnetisches Metallstück 21 und ein Magnetfeldsensor 22 angeordnet. Umgekehrt befindet sich auch in dem zweiten Hörgerät 2 bzw. in dessen Schale 20 ein Permanentmagnet 23 und in der Schale 10 des ersten Hörgeräts 1 ein zugehöriges ferromagnetisches Metallstück 12 und ein Magnetfeldsensor 13.In the shell 10 of the first hearing aid 1 is a permanent magnet 11. In the hearing aid shell 20 of the second hearing aid 2, a ferromagnetic metal piece 21 and a magnetic field sensor 22 is arranged , Conversely, in the second hearing device 2 or in its shell 20 is a permanent magnet 23 and in the shell 10 of the first hearing aid 1, an associated ferromagnetic metal piece 12 and a magnetic field sensor thirteenth

Werden die Hörgeräte 1, 2 nicht getragen, führt der Nutzer die Hörgeräte-Gehäuse 10, 20 zusammen, so dass sie durch Magnetkraft 3, eventuell unterstützt durch geometrische Strukturen ("Nut und Feder"), zusammenhalten. Der jeweilige Magnetfeldsensor 13, 22 detektiert das Feld des entsprechenden Permanentmagneten 11, 23 und schaltet daraufhin das dazugehörige Hörgerät 1, 2 ab. Sind wie im vorliegenden Beispiel beide Hörgeräte spiegelbildlich ausgestattet, so werden bei Annäherung beide Hörgeräte 1, 2 abgeschaltet.If the hearing aids 1, 2 are not worn, the user brings the hearing aid housings 10, 20 together so that they are held together by magnetic force 3, possibly supported by geometric structures ("tongue and groove"). The respective magnetic field sensor 13, 22 detects the field of the corresponding permanent magnet 11, 23 and then switches off the associated hearing aid 1, 2 from. If, as in the present example, both hearing aids are equipped with a mirror image, both hearing aids 1, 2 are switched off when approaching.

Das Signal der Magnetfeldsensoren 13, 22 kann auch dazu verwendet werden, die Elektronik des jeweiligen Hörgeräts 1, 2 zu steuern. Beispielsweise kann das Hörgerät in einen so genannten "Sleep-Modus" geschaltet werden, wenn sich das andere Hörgerät in der Nähe befindet, so dass der Energieverbrauch des Hörgeräts entsprechend reduziert wird. Darüber hinaus kann es auch sinnvoll sein, lediglich die Lautstärke bzw. die Verstärkung des Hörgeräts zu reduzieren, wenn sich das andere Hörgerät in der Nähe befindet, was auf den Nichtgebrauch der Hörgeräte hindeutet. Des Weiteren kann das Signal des Magnetfeldsensors dazu benutzt werden, eine Kommunikationsschnittstelle für eine drahtlose Verbindung abzuschalten.The signal of the magnetic field sensors 13, 22 can also be used to control the electronics of the respective hearing device 1, 2. For example, the hearing device can be switched to a so-called "sleep mode" when the other hearing device is in the vicinity, so that the energy consumption of the hearing device is correspondingly reduced. In addition, it may also be useful to reduce only the volume or the gain of the hearing aid when the other hearing aid is in the vicinity, which indicates the disuse of the hearing aids. Furthermore, the signal of the magnetic field sensor can be used to switch off a communication interface for a wireless connection.

Die Magnetfeldsensoren 13, 22 können als Hall-Sonde ausgeführt werden, wobei das Abschalten des Hörgeräte-Chips elektrisch erfolgt. Alternativ kann auch ein mechanischer Reed-Kontakt, der bei Vorhandensein eines Magnetfelds den Stromkreis öffnet, verwendet werden. In letzterem Fall erfolgt ein mechanisches Öffnen des Stromkreises.The magnetic field sensors 13, 22 can be designed as a Hall probe, whereby the switching off of the hearing aid chip takes place electrically. Alternatively, a mechanical reed contact that opens the circuit in the presence of a magnetic field may also be used. In the latter case, a mechanical opening of the circuit takes place.

Verfügen beide Hörgeräte 1, 2 über eine drahtlose Kommunikationsverbindung, so genügt es, wenn ein Permanentmagnet-Magnetfeldsensor-Paar in den beiden Hörgeräten untergebracht ist. In diesem Fall wird dann bei Annäherung der beiden Hörgeräte aneinander ein entsprechendes Sensorsignal generiert und zur Steuerung des Hörgeräts mit dem Sensor verwendet. Mithilfe der Kommunikationsverbindung wird das Sensorsignal auch an das andere Hörgerät übertragen, so dass es auch dort verwertet werden kann.If both hearing aids 1, 2 have a wireless communication connection, then it is sufficient if a pair of permanent magnet magnetic field sensors is accommodated in the two hearing aids. In this case, when the two hearing aids approach each other, a corresponding sensor signal is then generated and used to control the hearing device with the sensor. The communication connection becomes the sensor signal also transmitted to the other hearing aid, so that it can be used there as well.

Erfindungsgemäß lässt sich so ein Ein-/Ausschalter realisieren, der keinerlei Bedienelemente oder Löcher im Gehäuse erfordert. Somit kann das Hörgerät besser gegen Wasser geschützt werden. Ein weiterer Vorteil besteht darin, dass das Ein- und Ausschalten des Hörgerätesystems automatisch und intuitiv erfolgt.According to the invention can be realized as an on / off switch that requires no controls or holes in the housing. Thus, the hearing aid can be better protected against water. Another advantage is that the switching on and off of the hearing aid system is automatic and intuitive.
