Abstract

The housing has an opening for barometric pressure balance of a sound channel and covered by an air permeable material, where the air permeable material is an air permeable membrane or a tiling or porous material i.e. Gore-Tex(RTM: waterproof/breathable fabric).

Description

Bei In-dem-Ohr-Hörgeräten muss die Belüftung, bzw. der barometrische Druckausgleich über das Gehäuse des Hörers (Receivers), d. h. durch eine kleine Ventilationsöffnung im Hörergehäuse (Receivergehäuse) sichergestellt werden. Die Ventilationsöffnung ist normalerweise in der Membran oder zwischen dem Vorder- und Rückvolumen.at In-the-ear hearing aids must the ventilation, or the barometric pressure compensation via the housing of the receiver (receiver), d. H. by a small ventilation opening ensured in the receiver housing (receiver housing) become. The ventilation opening is usually in the membrane or between the front and back volumes.

Die genannte kleine Öffnung wirkt sich aber nachteilig auf die akustischen Feedback-Eigenschaften des Hörgeräts aus.The called small opening but has a negative effect on the acoustic feedback properties of the hearing aid.

Bisher wurde das Problem durch eine sehr kleine Öffnung im Hörer-Gehäuse gelöst. Jedoch kann diese sehr kleine Öffnung sehr leicht durch Schmutz (Cerumen, im Schweiß gelöstes Hautfett, Herstellungsrückstände) verschlossen und somit unwirksam werden.So far the problem was solved by a very small opening in the receiver housing. However, this can be very small opening very easily by dirt (cerumen, dissolved in sweat skin fat, manufacturing residues) closed and thus become ineffective.

Der Erfindung liegt die Aufgabe zugrunde, die genannte Problematik zu lösen.Of the Invention is based on the object, said problem to solve.

Gemäß der Erfindung wird die genannte Öffnung im Hörer-Gehäuse (Receiver-Gehäuse) mit einem Abdeckungsmaterial, z. B. einer luftdurchlässigen Membran bzw. einem fliesähnlichen oder porösem Material (z. B. Gore-Tex) abgedeckt (siehe Figur der Zeichnung, die ein Hörergehäuse darstellt). Messungen bezüglich der akustischen Eigenschaften dieser Materialien wurden im Rahmen der Versuche, eine geeignete Mikrofonabdeckung zu finden, durchgeführt und hatten Dämpfungswerte von 20 db und mehr ergeben. Diese für eine Mikrofonabdeckung negativen Eigenschaften erweisen sich hier als vorteilhaft, da sie die Feedback-Stabilität erhöhen.According to the invention becomes the opening mentioned in the receiver housing (receiver housing) with a cover material, e.g. As an air-permeable membrane or a flow-like or porous Material (eg Gore-Tex) covered (see figure of the drawing, which represents a listener housing). Measurements regarding The acoustic properties of these materials were in the frame the attempts to find a suitable microphone cover, performed and had attenuation values of 20 db and more. This negative for a microphone cover Properties prove to be beneficial as they increase feedback stability.

Durch die größere Oberfläche des Materials ist zudem die Wahrscheinlichkeit eines Verschlusses der Öffnung durch Schmutz wesentlich geringer.By the larger surface of the Material is also the likelihood of closure of the opening through Dirt much lower.
