Description

Die vorliegende Erfindung betrifft einen Ohreinsatz für ein Hörsystem, insbesondere ein Hörgerät, mit einem Formkörper, der in den Gehörgang eines Ohrs einpassbar ist, einer Kapsel, die entnehmbar in dem Formkörper angeordnet ist, und einem Hörer zum Beschallen des Ohrs, der in der Kapsel angeordnet ist.The present invention relates to an ear insert for a Hearing system, in particular a hearing aid, with a molded body, which can be fitted in the ear canal of an ear, a capsule, which is removably disposed in the shaped body, and a Earpiece for sonicating the ear, which is placed in the capsule is.

Bei Hochtonhörgeräten mit einer weitgehend offenen Versorgung stellen zum einen die Schallabstrahlung aus dem Vent (der Öffnung) und zum anderen die Dämpfungseigenschaften des Schallschlauchs für hohe Frequenzen starke Beeinträchtigungen dar. Daher ist in diesen Fällen eine Auslagerung des Hörers von großem Vorteil. Dabei wird der Hörer in eine Otoplastik bzw. ein Ohrpassstück fest eingesetzt bzw. eingegossen. Über eine Kabelverbindung wird der Hörer mit dem Hörgerätemodul verbunden, das beispielsweise hinter dem Ohr angebracht ist. Dieser Aufbau bringt jedoch den Nachteil mit sich, dass im Servicefall bei Ausfall oder Verschmutzung des Hörers in der Otoplastik diese ausgetauscht werden muss, was mit einem beträchtlichen Aufwand und Kosten verbunden ist, da jede Otoplastik individuell geformt ist.For treble sound devices with a largely open supply on the one hand, the sound radiation from the vent (the Opening) and on the other the damping properties of the Sound tube for high frequencies severely impaired Therefore, in these cases, an outsourcing of the listener of great advantage. In doing so, the listener becomes an earmold or an earmold firmly inserted or poured. about a cable connection becomes the handset with the hearing aid module connected, for example, behind the ear is attached. However, this structure has the disadvantage that in Service case in case of failure or contamination of the handset in the Otoplastik this must be replaced, what with a considerable Effort and costs associated with each earmold individually shaped.

In diesem Zusammenhang sind Otoplastiken bekannt, an die ein Hörer von extern ankoppelbar ist. Eine derartige Anordnung wird bei Taschengeräten verwendet. Für den üblichen Gebrauch von HdOs ist diese Konstruktion allerdings in der Regel zu groß in der Ausführung.In this context, earmolds are known to the one Handset can be connected externally.

Die Modulschale ist in sich geschlossen und enthält beliebige elektrische und/oder elektromechanische Bauteile, z. B. einen Hörer und ein Mikrofon. Nach dem Einsetzen verschwindet der Ohreinsatz größtenteils im inneren Hörkanal und ist dadurch praktisch nicht sichtbar. Der Schall wird von dem Hörer über einen kleinen röhrenförmigen Kanal zum Trommelfell geleitet.Furthermore, EP 0 288 822 discloses a behind-the-ear hearing aid (BTE) known, whose Ohrhreinsatz a to the Contour of the inner auditory canal adapted earmold and a includes module shell usable therein. The module shell is self-contained and contains any electrical and / or electromechanical components, eg. B. a handset and a microphone. After insertion, the ear piece disappears mostly in the inner auditory canal and is therefore practical not visible. The sound is heard from the listener over one small tubular channel led to the eardrum.

Erfindungsgemäß wird diese Aufgabe gelöst durch einen Ohreinsatz für ein Hörsystem mit einem Formkörper, der in den Gehörgang eines Ohrs einpassbar ist, und einem Hörer zum Beschallen des Ohrs, der entnehmbar in dem Formkörper angeordnet ist, wobei ein nach akustischen Bedingungen geformter Schallaustritt zwischen dem Hörer und der Seite des Formkörpers ausgebildet ist, die in dem Zustand, in welchem der Ohreinsatz in den Gehörgang eingesetzt ist, dem Trommelfell zugewandt ist. Der Schallaustritt ist in der Kapsel ausgebildet. Dadurch ist zwar die Kapsel für den Hörer etwas teurer in seinen Herstellungskosten, der Formkörper ist hingegen kostengünstiger herzustellen. Vorzugsweise ist der Schallaustritt trichterförmig ausgebildet. Idealerweise besitzt der Schallaustritt die Form eines Exponentialhorn, so dass eine optimale Impedanzanpassung gegeben ist. An der dem Trommelfell abgewandten Seite des Formkörpers ist ein Deckel angebracht, mit dem eine Ausnehmung in dem Formkörper verschließbar ist, in welche die Kapsel eingesetzt ist. Damit kann die Kapsel verhältnismäßig einfach geformt sein, ohne dass ein ungewolltes Herausrutschen des Hörers aus dem Ohreinsatz zu befürchten wäre. Optional kann der Deckel von dem Formkörper abnehmbar gestaltet sein, was unter Umständen zu Montagevorteilen führt.According to the invention, this object is achieved by an ear insert for a hearing aid with a molded body that enters the ear canal an ear is tunable, and a listener for sonicating of the ear removably disposed in the molded body is one being shaped according to acoustic conditions Sound emission between the listener and the side of the molding formed in the state in which the ear insert inserted into the ear canal, facing the eardrum is.

Eine dem Trommelfell zugewandte Öffnung des Schallaustritts kann hierbei eine größere Fläche aufweisen als eine dem Hörer zugewandte Öffnung des Schallaustritts.An eardrum-facing opening of the sound outlet This can have a larger area than a listener facing opening of the sound outlet.

Insbesondere für Hochtonhörgeräte ist somit eine verbesserte akustische Impedanzanpassung gegeben.In particular for Hochtonhörgeräte is thus an improved given acoustic impedance matching.

Der Schallaustritt kann in dem Formkörper ausgebildet sein. In diesem Fall ist eine Kapsel bzw. ein Adapter für den Hörer, die/der den leichten Austausch des Hörers gestattet, sehr kostengünstig herzustellen.The sound outlet can be formed in the shaped body. In this case, a capsule or an adapter for the listener, the one who allows the easy exchange of the listener, very inexpensive to produce.

Die Kapsel kann von der dem Trommelfell zugewandten Seite aus dem Formkörper entnehmbar sein. Dies hat den Vorteil, dass - einen entsprechenden Anschlag vorausgesetzt - die Kapsel mit dem Hörer nicht aus dem Ohreinsatz rutschen kann.The capsule may be from the side facing the eardrum be removed from the molding. This has the advantage that - assuming a corresponding stop - the capsule with the handset can not slip out of the ear piece.
