Description

Die Erfindung betrifft ein Im-Ohr-Hörgerät mit einem Hörgeräte-Ladeschaltkreis, der einen aufladbaren elektrischen Energiespeicher aufweist, der nach dem Einlegen des Hörgeräts in einen Ladebehälter mit einem Ladeschaltkreis verbindbar ist.The invention relates to an in-the-ear hearing aid with a Hearing aid charging circuit, which is a rechargeable electric Has energy storage, after inserting the hearing aid connectable to a charging circuit in a charging container is.

Hörgeräte sind auch in der Bauart als Im-Ohr-Hörgeräte mit aufladbaren elektrischen Energiespeichern, nämlich aufladbaren Batterien bzw. Akkumulatoren bekannt. Eine Schwierigkeit für den Anwender besteht jedoch darin, daß der aufladbare elektrische Energiespeicher dem Hörgerät entnommen werden muß, um den Energiespeicher in einem gesonderten Ladegerät wieder aufzuladen.Hearing aids are also available as in-the-ear hearing aids rechargeable electrical energy stores, namely rechargeable Batteries or accumulators known. A problem for the user, however, is that the rechargeable electrical energy storage can be removed from the hearing aid must to the energy storage in a separate charger recharge.

Zur Erleichterung der Aufladung, bei der die Ladezeit auch überwacht werden muß, um ein Überladen zu vermeiden, sind Hörgeräte bekannt, bei denen der elektrische Energiespeicher fest eingebaut ist und über von außen zugängliche Ladekontakte mit dem Ladegerät verbunden werden kann.To facilitate charging, the charging time also must be monitored to avoid overloading Hearing aids known in which the electrical energy storage is permanently installed and via externally accessible charging contacts can be connected to the charger.

Bei einem bekannten Im-Ohr-Hörgerät der eingangs genannten Gattung (WO 93/18629) wird das Hörgerät in eine Mulde eines Ladebehälters eingelegt. Aus der Wandfläche der Mulde ragende Kontaktstifte treten mit den Ladekontakten des Hörgeräts in Verbindung, um den elektrischen Energiespeicher aufzuladen. Hierbei ist nachteilig, daß vor allem bei individuell dem Ohr angepaßten Im-Ohr-Hörgeräten eine individuelle Anpassung der Ladekontakte erforderlich ist. Dies ist aufwendig und kann zu Fehlern führen.In a known in-the-ear hearing aid of the type mentioned Genre (WO 93/18629) is the hearing aid in a trough Loading container inserted. Protruding from the wall surface of the trough Contact pins come into contact with the hearing aid's charging contacts Connection to charge the electrical energy storage. The disadvantage here is that especially with the individual ear customized in-the-ear hearing aids Charging contacts are required. This is expensive and can be too Make mistakes.

Es ist zwar bei außerhalb des Ohres zu tragenden Hörgeräten bekannt (Zeitschrift "Hearing Instruments", Band 38, Nr. 7, Juli 1987), den elektrischen Energiespeicher induktiv aufzuladen, ohne daß der Energiespeicher aus dem Hörgerät herausgenommen werden müßte. Das Hörgerät ist jedoch wegen der Abmessungen der Spule sehr groß und daher wenig diskret und ästhetisch. Deshalb ist diese Technik für ein Im-Ohr-Hörgerät nicht geeignet.It is true with hearing aids to be worn outside the ear known (magazine "Hearing Instruments", volume 38, No. 7, July 1987), the electrical energy storage inductively charge without removing the energy storage from the hearing aid should be taken out. However, the hearing aid is due the dimensions of the coil are very large and therefore not very discreet and aesthetic. That is why this technique is for an in-the-ear hearing aid not suitable.

Aufgabe der Erfindung ist es daher, ein Im-Ohr-Hörgerät so auszugestalten, daß sein Energiespeicher in einfacher Weise aufgeladen werden kann.The object of the invention is therefore an in-the-ear hearing aid design that his energy storage in a simple manner can be charged.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Hörgeräte-Ladeschaltkreis eine über einen Gleichrichter mit dem elektrischen Energiespeicher verbundene Sekundärspule aufweist, die mit einer mit dem Ladeschaltkreis verbundenen Primärspule im Ladebehälter bei eingelegtem Hörgerät induktiv gekoppelt ist, und daß die Sekundärspule als eine den elektrischen Energiespeicher umgebende kernlose Spule ausgeführt ist. This object is achieved in that the Hearing aid charging circuit using a rectifier the secondary coil connected to the electrical energy store has, which with a connected to the charging circuit Primary coil in the charging container when the hearing aid is inserted inductively is coupled, and that the secondary coil as the one coreless coil surrounding electrical energy storage is executed.

Erst durch die sehr platzsparende Anordnung der Sekundärspule, die ohne Kern ausgeführt wird, ist es möglich, den hierfür erforderlichen zusätzlichen Platzbedarf so gering zu halten, daß die Unterbringung auch in einem Im-Ohr-Hörgerät möglich ist. Die induktive Koppelung mit der Primärspule des Ladeschaltkreises geschieht in einfacher Weise dadurch, daß das Im-Ohr-Hörgerät in den Ladebehälter eingelegt wird. Die geringe Richtungsabhängigkeit der kernlosen Sekundärspule macht ein genaues Ausrichten des Hörgeräts im Ladebehälter überflüssig; es genügt, das Hörgerät in den als übliches Aufbewahrungsetui gestalteten Ladebehälter einzulegen.Only through the very space-saving arrangement of the secondary coil which runs without a core, it is possible to run the the additional space required for this to be so small keep that placement even in an in-the-ear hearing aid is possible. The inductive coupling with the primary coil of the Charging circuit happens in a simple manner in that the in-the-ear hearing aid is placed in the charging case. The low directional dependence of the coreless secondary coil makes a precise alignment of the hearing aid in the loading container superfluous; it is enough to put the hearing aid in as usual Insert storage case designed loading container.

Der geringe Platzbedarf der erfindungsgemäß ausgeführten Sekundärspule beeinträchtigt die bei einem Im-Ohr-Hörgerät wichtige individuelle Anpassungsmöglichkeit an das Ohr des Anwenders nicht.The small space requirement of those designed according to the invention Secondary coil affects that in an in-the-ear hearing aid important individual adaptation to the ear of the User.

Gemäß einer bevorzugten Ausführung der Erfindung ist vorgesehen, daß der elektrische Energiespeicher im Hörgeräte-Ladeschaltkreis mit einem Spannungsmeßgerät verbunden ist, dessen Ausgangssignal über einen Modulator der Sekundärspule zugeführt wird, und daß der Ladeschaltkreis eine über einen Demodulator an die Primärspule angeschlossene Auswerteschaltung aufweist, die über eine Ladesteuerung den Energiefluß zur Primärspule steuert.According to a preferred embodiment of the invention provided that the electrical energy storage in the hearing aid charging circuit is connected to a voltage measuring device, its output signal via a modulator of the secondary coil is supplied, and that the charging circuit one over Demodulator evaluation circuit connected to the primary coil has the energy flow via a charge control controls to the primary coil.

Das vom Spannungsmeßgerät des Hörgeräte-Ladeschaltkreises gelieferte Ausgangssignal, das eine Information über den Ladezustand des Energiespeichers liefert, wird induktiv von der Sekundärspule auf die Primärspule übertragen und in der Auswerteschaltung des Ladeschaltkreises dazu benutzt, den Ladevorgang so zu steuern, daß ein Überladen vermieden wird. Damit ist auch eine Schnelladung des Energiespeichers möglich, ohne daß die Gefahr einer Schädigung besteht.That from the voltage measuring device of the hearing aid charging circuit delivered output signal, which provides information about the The state of charge of the energy storage device is inductively charged by the secondary coil transferred to the primary coil and in the Evaluation circuit of the charging circuit used to To control the charging process so that overcharging is avoided. This is also a quick charge of the energy storage possible without the risk of damage.

Der elektrische Energiespeicher kann mit zwei von außen zugänglichen Prüfkontakten verbunden sein, die es ermöglichen, den elektrischen Energiespeicher, insbesondere Akkumulator, zu testen, ohne das Hörgerät zu öffnen. Damit kann in einfacher Weise geprüft werden, ob innerhalb der üblichen Gebrauchszeit eines im Ohr-Hör-Geräts ein Auswechseln des Energiespeichers erforderlich ist.The electrical energy storage device can have two from the outside accessible test contacts, which make it possible to the electrical energy storage, in particular Battery to test without opening the hearing aid. In order to can be checked in a simple manner whether within the a normal usage time of an in-the-ear device the energy storage is required.

Gemäß einer weiteren bevorzugten Ausführung der Erfindung ist vorgesehen, daß die Primärspule in den Behälterinnenwänden des Ladebehälters verlegt ist, die einen Behälterinnenraum umgeben. Dadurch kann der Ladebehälter zugleich als Aufbewahrungsetui für das Im-Ohr-Hörgerät verwendet werden, ohne daß die Primärspule sichtbar wäre oder stören würde. Die durch den Betrieb der Primärspule hervorgerufene Erwärmung des Behälterinnenraums dient zugleich dazu, das Im-Ohr-Hörgerät während der Aufbewahrung zu trocknen.According to a further preferred embodiment of the invention provided that the primary coil in the container inner walls of the loading container, which is a container interior surround. As a result, the loading container can also be used as Storage case for the in-the-ear hearing aid can be used without the primary coil being visible or disturbing. The heating caused by the operation of the primary coil of the container interior also serves as the in-the-ear hearing aid to dry during storage.
