Hearing device with ear canal microphone

1. A hearing device, comprising:

a plastic mold sized and configured for insertion in a human ear;

a sound exit orifice located in the plastic mold;

a cerumen protection system located in the sound exit orifice; and

a microphone located in the cerumen protection system;

wherein a cross-section of the microphone is smaller than a cross-section of the cerumen protection system upon positioning said microphone within the sound exit orifice.

2. The hearing device as claimed in claim 1 , wherein the hearing device is an in-the-ear hearing device with the plastic mold being a hearing device shell.

3. The hearing device as claimed in claim 1 , wherein the hearing device is a behind-the-ear hearing device with the plastic mold being an otoplastic which is inserted into the human ear.

4. The hearing device as claimed in claim 1 , wherein the cerumen protection system is closed off on a surface of the plastic mold by an open-pore membrane.

5. The hearing device as claimed in claim 1 , wherein the cerumen protection system is closed off on a surface of the plastic mold by a closed protective membrane.

6. The hearing device as claimed in claim 1 , wherein the cerumen protection system has a funnel-shape.

7. The hearing device as claimed in claim 6 , wherein the cerumen protection system comprises a conical segment which passes into a tubular segment extending to a surface of the plastic mold.

8. The hearing device as claimed in claim 7 , wherein the microphone is in the tubular segment of the cerumen protection system with a microphone sound recording surface arranged parallel to the sound exit orifice.

9. The hearing device as claimed in claim 7 , wherein the microphone is in the tubular segment of the cerumen protection system with a microphone sound recording surface arranged perpendicular to the sound exit orifice.

10. The hearing device as claimed in claim 1 , wherein the cerumen protection system has an elliptical cross-section.

11. The hearing device as claimed in claim 1 , wherein the microphone has a circular cross-section.

12. The hearing device as claimed in claim 1 , wherein the plastic mold has a tip which is inserted into a human ear canal.

13. A method for making a hearing device, comprising:

providing a plastic mold for insertion in a human ear;

arranging a sound exit orifice within the plastic mold;

arranging a cerumen protection system within the sound exit orifice; and

arranging a microphone within the cerumen protection system; and

adjusting a cross-section of the microphone to be smaller than a cross-section of the cerumen protection system.

14. The method as claimed in claim 13 , wherein the cerumen protection system has a funnel-shape.

15. The method as claimed in claim 13 , wherein the plastic mold has a tip which is inserted into a human ear canal.
