Abstract

The device has a funnel-shaped support (1), inserted with its tapered end (2) at a sound outlet of an earpiece of a hearing aid, including a sound opening (3) on its opposite end. The opening is overstretched by a protection membrane (4), which is tensioned for protection against penetration to the cerumen (ear wax) through the opening, where the luminance contrast between the membrane and the support is larger than 0.9. The color of the membrane is spaced at an angle of 60 degree from the color of the support in a blue-yellow-red-color circle.

Description

Die vorliegende Erfindung betrifft eine Cerumenschutzvorrichtung für ein Hörgerät oder eine andere Hörvorrichtung, z. B. ein Headset, mit einem Träger, der eine Schalldurchtrittsöffnung aufweist, und eine Membran, die zum Schutz gegen eindringendes Cerumen über die Schalldurchtrittsöffnung gespannt ist.The present invention relates to a cerumen protection device for a hearing aid or other hearing device, for. As a headset, with a carrier having a sound passage opening, and a membrane which is stretched over the sound passage opening to protect against penetrating cerumen.

Hörgeräte sind im täglichen Einsatz verschiedensten Stoffen ausgesetzt, die Verschmutzungen in den Geräten und besonders in den Wandlern der Geräte verursachen können. Derartige Stoffe sind insbesondere Schweiß und Cerumen. Verschmutzungen innerhalb der Wandler, nämlich der Mikrofone und Hörer, führen zu hohen Servicekosten, da die verschmutzten Wandler gereinigt und im schlimmsten Fall sogar ausgetauscht werden müssen.Hearing aids are exposed to various substances in daily use, which can cause soiling in the devices and especially in the transducers of the devices. Such substances are especially sweat and cerumen. Dirt within the transducers, namely the microphones and handsets, leads to high service costs, since the dirty transducers must be cleaned and in the worst case, even replaced.

Zur Lösung dieses Problems werden häufig offene Cerumenschutzsysteme eingesetzt, damit das Cerumen nicht ohne weiteres beispielsweise zum Hörer gelangen kann. Derartige offene Cerumenschutzsysteme können die Verschmutzung des Hörers aber nicht immer verhindern.To solve this problem, open wax protection systems are often used, so that the cerumen can not easily reach the listener, for example. However, such open cerumen protection systems can not always prevent the contamination of the listener.

Als alternative Lösung wird in der Druckschrift
DE 196 40 796 A1 ein Hörgerät vorgestellt, bei dem der Hörer durch eine Membran vom Trommelfell abgeschlossen ist. Ebenso zeigt die Druckschrift US 2005/0018866 A1 einen akustisch transparenten Verschmutzungsschutz für Audiowandler. Ein Schutzfilm soll feste, flüssige und gasförmige Kontaminenten von dem akustischen Wandler abhalten.As an alternative solution is in the document
DE 196 40 796 A1 a hearing aid is presented in which the listener is completed by a membrane of the eardrum. Likewise, the document shows US 2005/0018866 A1 an acoustically transparent dirt protection for audio converters. A protective film is intended to prevent solid, liquid and gaseous contaminants from the acoustic transducer.

Da die Schutzmembranen aus akustischen Gründen sehr dünn sind, sind sie auch gegenüber Beschädigungen und Zerstörungen sehr anfällig. Daher muss ständig überprüft werden, ob die Membran noch intakt ist. Hierbei besteht jedoch die Problematik, dass die Schallöffnung, über die die Membran gespannt ist, in der Regel sehr klein ist, so dass eine Beschädigung der Membran nur mit Mühe optisch wahrgenommen werden kann.Since the protective membranes are very thin for acoustic reasons, they are also very susceptible to damage and destruction. Therefore, it must be constantly checked if the Membrane is still intact. In this case, however, there is the problem that the sound opening, over which the membrane is stretched, is usually very small, so that damage to the membrane can be perceived optically only with difficulty.

Auch die Firma Sonion bietet Hörgeräte an, deren Hörerausgang mit einer Membran gegen Cerumen geschützt werden soll. Zur Inspektion dieser Membran wird in einer "Application Note", "C-Barrier", vom 01.10.2005 unter www.sonion.com auf Seite 15 vorgeschlagen, eine Taschenlampe zu verwenden. Wenn die Membran intakt ist, reflektiert sie das Licht der Taschenlampe unter dem entsprechenden Winkel. Wenn die Membran verschmutzt oder beschädigt ist, wird das Licht nicht reflektiert. Dieses Prüfungsverfahren ist jedoch nur für einen beschränkten Personenkreis ohne weiteres ausführbar, da es verhältnismäßig kompliziert ist.Also the company Sonion offers hearing aids, whose listener output is to be protected with a membrane against Cerumen. For the inspection of this membrane, it is proposed to use a flashlight in an "Application Note", "C-Barrier", dated 01.10.2005 at www.sonion.com on page 15. When the membrane is intact, it reflects the light from the flashlight at the appropriate angle. If the membrane is dirty or damaged, the light will not be reflected. However, this examination procedure is readily feasible only for a limited number of persons, since it is relatively complicated.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, eine Cerumenschutzvorrichtung vorzuschlagen, bei der die Beschädigung einer Membran leichter festgestellt werden kann.The object of the present invention is therefore to propose a cerumen protection device in which the damage of a membrane can be more easily detected.

Erfindungsgemäß wird diese Aufgabe gelöst durch eine Cerumenschutzvorrichtung für ein Hörgerät mit einem Träger, der eine Schalldurchtrittsöffnung aufweist, und einer Membran, die zum Schutz gegen eindringendes Cerumen über die Schalldurchtrittsöffnung gespannt ist, wobei der Helligkeitskontrast zwischen der Membran und dem Träger größer als 0,1 ist.According to the invention this object is achieved by a cerumen protection device for a hearing aid with a carrier having a sound passage opening, and a membrane that is stretched over the sound passage opening to protect against penetrating cerumen, wherein the brightness contrast between the membrane and the support greater than 0.1 is.

Ferner ist es erfindungsgemäß vorgesehen, eine Cerumenschutzvorrichtung für ein Hörgerät mit einem Träger, der eine Schalldurchtrittsöffnung aufweist, und einer Membran, die zum Schutz gegen eindringendes Cerumen über die Schalldurchtrittsöffnung gespannt ist, wobei die Farbe der Membran von der Farbe des Trägers auf einem Blau-Gelb-Rot-Farbkreis mindestens 60° beabstandet ist.Furthermore, it is provided according to the invention, a cerumen protection device for a hearing aid with a carrier having a sound passage opening, and a membrane which is stretched over the sound passage opening to protect against penetrating cerumen, wherein the color of the membrane of the color of the carrier on a blue Yellow-red color circle is at least 60 ° apart.

In vorteilhafter Weise besteht erfindungsgemäß ein für das Auge deutlich wahrnehmbarer Kontrast zwischen der Schutzmembran und dem Träger, so dass beim Reißen der Membran der darunterliegende Träger sichtbar wird und somit eine Beschädigung leicht erkannt werden kann.Advantageously, according to the invention there is a clearly perceptible contrast between the protective membrane for the eye and the wearer so that when the membrane ruptures, the underlying wearer becomes visible and thus damage can easily be detected.

Vorzugweise ist der Helligkeitskontrast zwischen der Membran und dem Träger größer 0,3, größer 0,5, größer 0,7 oder sogar größer 0,9. Je stärker der Kontrast zwischen den beiden Komponenten ist, desto leichter lässt sich eine Beschädigung der Membran feststellen. Damit wird die akustische Erkennung eines Defekts der Membran wesentlich einfacher als bei den üblicherweise verwendeten transparenten Membranen.Preferably, the brightness contrast between the membrane and the support is greater than 0.3, greater than 0.5, greater than 0.7 or even greater than 0.9. The stronger the contrast between the two components, the easier it is to detect damage to the membrane. Thus, the acoustic detection of a defect of the membrane is much easier than with the commonly used transparent membranes.

Wird der Farbkontrast zwischen der Membran und dem Träger ausgenützt, so kann es hilfreich sein, wenn die Farbe der Membran von der Farbe des Trägers auf dem Farbkreis mindestens 90° beabstandet ist. Noch günstiger ist es, wenn die beiden Farben im Wesentlichen komplementär sind. Dadurch ist auch bei schlechten Lichtverhältnissen in der Regel eine gute Möglichkeit gegeben, die Membran zuverlässig zu untersuchen.If the color contrast between the membrane and the carrier is utilized, it may be helpful if the color of the membrane is at least 90 ° apart from the color of the carrier on the color wheel. It is even better if the two colors are essentially complementary. As a result, even in poor lighting conditions, there is usually a good opportunity to examine the membrane reliably.

Bei einer speziellen Ausführungsform kann der Träger, auf dem die Membran aufgespannt ist, trichterförmig sein. Damit kann im Falle eines Risses hinter einem Großteil der Membran der Träger optisch wahrgenommen werden.In a specific embodiment, the support on which the membrane is mounted may be funnel-shaped. Thus, in the case of a crack behind a large part of the membrane, the carrier can be perceived optically.

Die vorliegende Erfindung wird nun anhand der beigefügten Zeichnungen näher erläutert, in denen zeigen:

FIG 1
einen Querschnitt durch eine erfindungsgemäße Cerumenschutzvorrichtung und
FIG 2
einen Blau-Gelb-Rot-Farbkreis der Malerei.
The present invention will now be explained in more detail with reference to the accompanying drawings, in which:
FIG. 1
a cross section through a cerumen protection device according to the invention and
FIG. 2
a blue-yellow-red color circle of painting.

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.

Die in FIG 1 schematisch dargestellte Cerumenschutzvorrichtung weist einen im Wesentlichen trichterförmigen Träger 1 auf. Mit seinem verjüngten Ende 2 wird der Träger auf einen Schallauslaß eines nicht dargestellten Hörers eines Hörgeräts gesteckt. An seinem gegenüberliegenden Ende weist der Träger 1 eine weite Schallöffnung 3 auf, die von einer Membran 4 überspannt ist.The wax protection device shown schematically in FIG. 1 has a substantially funnel-shaped support 1. With its tapered end 2 of the carrier is plugged into a sound outlet of a receiver, not shown, a hearing aid. At its opposite end, the carrier 1 has a wide sound opening 3, which is spanned by a membrane 4.

Die Membran 4 besitzt beispielsweise eine dunkle Farbe, während der Membran-Träger 1 hell gefärbt ist. Durch diesen deutlichen Hell-Dunkel-Kontrast lässt sich ein Defekt der Membran 4 leicht erkennen, da durch die beschädigte, dunkle Membran 4 der helle Träger 1 sichtbar wird.The membrane 4 has, for example, a dark color, while the membrane support 1 is lightly colored. Due to this clear bright-dark contrast, a defect of the membrane 4 can be easily recognized, since the light carrier 1 becomes visible through the damaged, dark membrane 4.

Der Helligkeitsunterschied zwischen der Membran 4 und dem Träger 1 bestimmt den Helligkeitskontrast zwischen beiden Komponenten. Allgemein ist der Kontrast K definiert als:
K = (Imax - Imin) / (Imax + Imin). Dabei bezeichnet Imax die Lichtstärke der helleren und Imin die Lichtstärke der dunkleren Komponente. Die Lichtstärke selbst stellt den Quotienten aus Lichtstrom und Raumwinkel dar. Der in diesem Dokument verwendete Begriff "Helligkeitskontrast" bezieht sich auf obige Definition.The brightness difference between the membrane 4 and the carrier 1 determines the brightness contrast between the two components. In general, the contrast K is defined as:
K = (I max -I min ) / (I max + I min ). Here I max denotes the light intensity of the lighter and I min the light intensity of the darker component. The luminous intensity itself represents the quotient of luminous flux and solid angle. The term "brightness contrast" used in this document refers to the above definition.

Sind die Membran und der Träger gleich hell, so ist Imax = Imin und somit K = 0. Ist hingegen eine der beiden Komponenten schwarz, d. h. Imin = 0, so ist K = 1. Der Kontrast K bewegt sich gemäß dieser Definition also zwischen den Werten 0 und 1.If the membrane and the carrier are equally bright, then I max = I min and thus K = 0. However, if one of the two components is black, ie I min = 0, K = 1. The contrast K moves according to this definition between the values 0 and 1.

Alternativ kann auch ein physiologischer Kontrast Kph betrachtet werden. Dieser ist wie folgt definiert: Kph = (Lob - LU)/(LU) .
Dabei bezeichnet Lob die Leuchtdichte eines Objekts und LU die Leuchtdichte der Umgebung. Damit das menschliche Auge Objekte in einer Umgebung wahrnehmen kann, muss zwischen dem Objekt und der Umgebung ein entsprechender Kontrast vorliegen. Im einfachsten Fall ist dies ein Unterschied in der Leuchtdichte. Dazu können noch Farbunterschiede hinzukommen. Der physiologische Kontrast Kph kann Werte zwischen -1 und +∞ annehmen. Die oben und in den Patentansprüchen angegebenen Helligkeitskontrastwerte können in entsprechende physiologische Kontrastwerte umgerechnet werden. Der Kern der Erfindung, dass zwischen Träger und Membran ein erhöhter Kontrast bestehen soll, bleibt davon unberührt.Alternatively, a physiological contrast K ph can also be considered. This is defined as follows: K ph = (L ob -L U ) / (L U ).
Here, L indicates whether the luminance of an object and L.sub.U the luminance of the environment. In order for the human eye to perceive objects in an environment, there must be a corresponding contrast between the object and the environment. In the simplest case, this is a difference in luminance. In addition color differences can be added. The physiological contrast K ph can assume values between -1 and + ∞. The brightness contrast values specified above and in the claims can be converted into corresponding physiological contrast values. The core of the invention, that between the carrier and membrane is to consist of increased contrast remains unaffected.

Der soeben beschriebene Helligkeitskontrast kann als eine physikalische Kontrastvariante angesehen werden. Das menschliche Auge ist aber auch in der Lage, andere optische Kontraste wahrzunehmen. Dementsprechend existieren beispielsweise in der Malerei neben dem Hell-Dunkel-Kontrast noch andere Kontrastdefinitionen wie: Kalt-Warm-Kontrast, Farbe-an-sich-Kontrast, Komplementärkontrast, Qualitätskontrast, Quantitätskontrast, Simultankontrast und Sukzessivkontrast. Unabhängig von der Kontrastart besteht das Wesen der vorliegenden Erfindung, wie erwähnt, darin, zwischen dem Träger und der Membran einen gut wahrnehmbaren Kontrast einzustellen.The brightness contrast just described can be considered as a physical contrast variant. The human eye is also able to perceive other optical contrasts. Accordingly, in contrast to painting, for example, there are other contrast definitions in addition to the light-dark contrast, such as: cold-warm contrast, color-to-itself contrast, complementary contrast, quality contrast, quantity contrast, simultaneous contrast and successive contrast. Regardless of the type of contrast, the essence of the present invention, as mentioned, is to set a good perceivable contrast between the support and the membrane.

In einem weiteren Ausführungsbeispiel wird nun der Farbkontrast zur besseren Wahrnehmung eines Defekts der Membran verwendet. Zur Definition des Farbkontrasts wird der in FIG 2 dargestellte Blau-Gelb-Rot-Farbkreis der Malerei verwendet. Die drei Hauptfarben blau, rot und gelb liegen auf dem Farbkreis in einem Abstand von 120°. Um einen für die Defekterkennung ausreichenden Farbkontrast zu verwirklichen, sollten die beiden verwendeten Farben mindestens 60° beabstandet sein. In FIG 2 ist dies für Dunkel- und Hellorange eingezeichnet. Bei mindestens 90° Abstand ist der Farbkontrast bereits deutlich höher, beispielsweise für Dunkelorgane und Gelb. Wenn die für die Membran 4 und den Träger 1 verwendeten Farben auf dem Farbkreis direkt gegenüberliegen, sind die beiden Farben zueinander komplementär und es ist der größte Farbkontrast erreicht (im gewählten Beispiel: Dunkelorgan und Türkis). Ein Defekt der Membran 4 lässt sich dann farblich am leichtesten erkennen.In a further embodiment, the color contrast is used to better perceive a defect of the membrane. To define the color contrast, the blue-yellow-red color circle of the painting illustrated in FIG. 2 is used. The three main colors blue, red and yellow lie on the color wheel at a distance of 120 °. In order to realize a sufficient color contrast for the defect detection, the two colors used should be at least 60 ° apart. In FIG. 2, this is indicated for dark and light orange. At a distance of at least 90 °, the color contrast is already significantly higher, for example for dark organs and yellow. If the colors used for the membrane 4 and the support 1 are directly opposite each other on the color wheel, the two colors are complementary to one another and the greatest color contrast is achieved (in the example chosen: dark organ and turquoise). A defect of the membrane 4 can then be easily recognized by color.

Wie auch immer der hohe Kontrast zwischen der Membran und dem Träger erzielt wird, die Wahrnehmung von Defekten der Membran wird auf alle Fälle deutlich erleichtert.However the high contrast between the membrane and the support is achieved, the perception of defects in the membrane is clearly facilitated in any case.
