Earwax protection device and method having a contrasting or colored membrane
View Patent ↗The present invention provides the ability to efficiently detect a defect of an earwax protection device membrane. To achieve this, a high contrast is set between the membrane and the associated carrier. If the membrane is torn, the carrier in the background can then easily be detected. A particularly suited brightness contrast between the membrane and the carrier is >0.1. In the case of a desired high color contrast, the color of the membrane should be spaced apart from the color of the carrier by at least 60° on a blue-yellow-red color circle.
1. A protection device for a hearing aid, comprising:
a carrier that has a sound passage opening;
a membrane that is tensioned over the sound passage opening in order to protect against penetrating earwax; and
wherein a visual attribute of the carrier and a visual attribute of the membrane are sufficiently different to permit detection of a defect in the membrane, said visual attribute comprising a brightness contrast between the membrane and the carrier is greater than 0.1.
2. The earwax protection device as claimed in claim 1 , in which the brightness contrast is greater than 0.3.
3. The earwax protection device as claimed in claim 1 , in which the brightness contrast is greater than 0.5.
4. The earwax protection device as claimed in claim 1 , in which the brightness contrast is greater than 0.7.
5. The earwax protection device as claimed in claim 1 , in which the brightness contrast is greater than 0.9.
6. A protection device for a hearing aid, comprising:
a carrier that has a sound passage opening;
a membrane that is tensioned over the sound passage opening in order to protect against penetrating earwax; and
wherein a visual attribute of the carrier and a visual attribute of the membrane are sufficiently different to permit detection of a defect in the membrane, said visual attribute comprising a color of the membrane being spaced apart by at least 60° from a color of the carrier on a blue-yellow-red color circle.
7. The earwax protection device as claimed in claim 6 , in which the colors are spaced apart by at least 90° on the color circle.
8. The earwax protection device as claimed in claim 6 , in which the two colors are essentially complementary.
9. The earwax protection device as claimed in claim 1 , wherein the carrier is of a funnel-shaped design.
10. The earwax protection device as claimed in claim 6 , wherein the carrier is of a funnel-shaped design.
11. The earwax protection device as claimed in claim 1 , wherein the carrier is of a step-funnel-shaped design.
12. The earwax protection device as claimed in claim 6 , wherein the carrier is of a step-funnel-shaped design.
13. A protection device for a hearing aid, comprising:
a carrier that has a sound passage opening;
a membrane that is tensioned over the sound passage opening in order to protect against penetrating earwax; and
wherein a visual attribute of the carrier and a visual attribute of the membrane are sufficiently different to permit detection of a defect in the membrane.
