Ein spezielles Problem dieser thermoelektrischen Wandler ist die Platzierung in einer Hörvorrichtung und insbesondere an einem Hörgerät.One special problem of these thermoelectric converters is the placement in a hearing device and in particular on a hearing aid.
Die Aufgabe der vorliegenden Erfindung besteht somit darin, eine Hörvorrichtung bzw. ein Hörgerät derart zu gestalten, dass möglichst effizient Energie durch einen thermoelektrischen Wandler gewonnen werden kann.The The object of the present invention is therefore a hearing device or a hearing aid in such a way to make that possible efficiently recovered energy through a thermoelectric converter can be.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine Hörvorrichtung mit einem Schallschlauch oder einem elektrischen Kabel zur Leitung eines Schalls oder elektrischen Signals in einen Gehörgang, und einem thermoelektrischen Wandler, der in/an dem Schallschlauch oder dem elektrischen Kabel zur Energieversorgung der Hörvorrichtung angeordnet ist.According to the invention this Task solved by a hearing device with a sound tube or an electric cable to the line a sound or electrical signal in an ear canal, and a thermoelectric converter located in / on the sound tube or the electrical cable for powering the hearing device is arranged.
Erfindungsgemäß sind somit an den Hörvorrichtungen Stellen geschaffen bzw. genutzt, die einen ausreichenden thermischen Gradienten aufweisen.Thus, according to the invention at the hearing aids Created or used jobs that have a sufficient thermal Have gradients.
Bei der Hörvorrichtung mit dem Schallschlauch ist es günstig, wenn der thermoelektrische Wandler im Querschnitt rechteckförmig ist, an den Schmalseiten das warme und kalte Ende aufweist und in dem Schallschlauch so angeordnet ist, dass das warme und kalte Ende den Mantel des Schallschlauchs berühren oder einen Teil von dem Mantel darstellen. Da der Schallschlauch üblicherweise am Kopf geführt wird, kann mit dem an liegenden Abschnitt des Schallschlauchs die gewünschte Wärme aufgenommen werden.at the hearing device with the sound tube it is convenient if the thermoelectric converter is rectangular in cross section, on the narrow sides has the warm and cold end and in the Sound tube is arranged so that the warm and cold end touch the jacket of the sound tube or part of it Sheath show. Since the sound tube is usually performed on the head, can with the adjacent section of the sound tube absorbed the desired heat become.
Die vorliegende Erfindung wird nun anhand der beigefügten Zeichnungen näher erläutert, in denen zeigen:The The present invention will now be described in detail with reference to the accompanying drawings, in which: show:
Die
nachfolgend näher
geschilderten Ausführungsbeispiele
gemäß den
Hörgeräte werden während des Betriebs am Kopf getragen. Das Ohrpassstück bei Hinter-dem-Ohr-Geräten oder das gesamte Gerät bei In-dem-Ohr-Geräten haben direkten Kontakt zum Inneren des Ohrkanals. Diese inneren Teile liegen relativ konstant auf der Körpertemperatur des Trägers. Der geringe Temperaturunterschied von wenigen Graden wird nun für die Energieerzeugung mit Hilfe eines thermoelektrischen Wandlers genutzt.Hearing aids are worn on the head during operation. The earmold for behind-the-ear devices or the entire device for in-the-ear devices have direct contact with the interior of the ear canal. These inner parts are relatively constant at the body temperature of the wearer. The small temperature difference of a few degrees is now used for energy generation with the help of a thermoelectric converter.
Beim Tragen des Hörgeräts bzw. der Otoplastik stellt sich ein Temperaturunterschied zwischen der Außenseite A und der Innenseite I ein. In Folge des Seebeck-Effekts wird hieraus elektrische Energie erzeugt, die der Hörvorrichtung bzw. dem Hörgerät zur Verfügung gestellt wird. Im Falle einer Otoplastik ist daher eine Kabelverbindung von dem thermoelektrischen Wandler TW zu dem Hinter-dem-Ohr-Hörgerät HdO vorzusehen. Eine wieder aufladbare Batterie, die von dem thermoelektrischen Element TW aufgeladen wird, dient als Sekundärenergiespeicher. Bei Hörgeräten mit hohem Energiebedarf ist von Zeit zu Zeit (z. B. über Nacht) ein Laden im ausgeschalteten Zustand notwendig. Dies kann durch eine externe Heizung und das erfindungsgemäße thermoelektrische Element oder durch ein Standard-Ladegerät erfolgen. Alternativ kann das Hörgerät auch im Ohr belassen und ausgeschaltet werden, so dass es durch die Körperwärme aufgeladen wird. Die Sekundärbatterie kann im Hörgerät selbst oder auch im Ohrpassstück (bei HdO-Systemen) untergebracht werden. Mit Hilfe der zusätzlichen Sekundärbatterie erreicht man eine deutlich längere Betriebsdauer von Geräten mit höherem Energiebedarf. Bei Hörgeräten mit geringem Energieverbrauch kann die Energieversorgung mit dem thermoelektrischen Element allein ausreichend sein.At the Carrying the hearing aid or the otoplastic presents a temperature difference between the outside A and the inside I a. As a result of the Seebeck effect, this becomes generates electrical energy provided by the hearing device or the hearing aid available becomes. In the case of an earmold is therefore a cable connection of the thermoelectric converter TW to the behind-the-ear hearing aid HdO provide. A rechargeable battery by the thermoelectric element TW is used as a secondary energy storage. For hearing aids with high energy demand is from time to time (eg overnight) a store in the off Condition necessary. This can be done by an external heater and that Thermoelectric according to the invention Element or by a standard charger. Alternatively, you can the hearing aid also in the Leave your ear and turned off, so that it is charged by the body heat becomes. The secondary battery can in the hearing aid itself or in the earmold (in BTE systems) be housed. With the help of the additional secondary battery you reach a much longer Operating time of devices with higher Energy demand. For hearing aids with low energy consumption can be the power supply to the thermoelectric Element alone be sufficient.

Wenn
das HdO hinter der Ohrmuschel OM am Kopf K getragen wird, liegt
der Schallschlauch SS direkt am Kopf an, wie dies in
Beim Tragen nimmt nun auch hier der thermoelektrische Wandler TW die Wärme vom Kopf K an seinem Wärmepol WP auf, während das nach außen weisende Ende des thermoelektrischen Wandlers TW kühl bleibt. Hierzu besitzt der thermoelektrische Wandler an seinem Wärmepol WP und Kältepol KP jeweils ein Metallelement, das vorzugsweise Teil der Mantelfläche des Schallschlauchs SS ist. Auf diese Weise lässt sich ein ungehinderter Wärmeübergang an den beiden Polen WP, KP erreichen.At the Wear here now takes the thermoelectric converter TW the Heat from Head K at his heat pole WP on while that to the outside pointing end of the thermoelectric converter TW remains cool. For this purpose, the thermoelectric converter has at its Wärmepol WP and cold pole KP in each case a metal element, which is preferably part of the lateral surface of the Sound tube SS is. In this way, one can be unhindered Heat transfer at the two poles WP, KP reach.
Die oben vorgestellte erfindungsgemäße Lösung für die Energieversorgung eines Hörgeräts kann sinngemäß auch beispielsweise für ein Head-Set oder eine andere mobile Hörvorrichtung verwendet werden.The Above presented solution according to the invention for the power supply a hearing aid can mutatis mutandis, for example for a head set or another mobile hearing device used become.
