Abstract

A hearing assistance device for a user comprising a housing, a three dimensional electronic substrate disposed in the housing, the substrate adapted to conform to a battery of the hearing assistance device and hearing assistance electronics mounted to the substrate.

Claims

1. A hearing assistance device, comprising:

a three-dimensional folded substrate including contours configured to form internal housing surfaces of the hearing assistance device, wherein the substrate included a plurality of slots and tabs configured to be engaged to add structural integrity to the substrate and maintain the folded shape;

hearing assistance electronics mounted to a flat portion of the substrate; and

a moisture resistant seal for the substrate, the seal configured to limit moisture ingress into the device.

2. The device of claim 1, wherein the moisture resistant seal includes a gasket.

3. The device of claim 1, wherein the moisture resistant seal includes glue.

4. The device of claim 1, wherein the moisture resistant seal includes rubber.

5. The device of claim 1, wherein the moisture resistant seal includes a polymer.

6. The device of claim 1, whererin the substrate includes a liquid crystal polymer (LCP).

7. The device of claim 1, wherein the substrate structurally forms a battery compartment.

8. The device of claim 1, further comprising an antenna connected to the hearing assistance electronics.

9. The device of claim 1, further comprising an antenna integrated with the substrate.

10. The device of claim 1, wherein the housing is a behind-the-ear housing.

11. The device of claim 1 wherein the housing is an in-the-ear housing.

12. The device of claim 1, wherein the housing is an in-the-canal housing.

13. The device of claim 1, wherein the housing is a receiver-in-the-canal housing.

14. The device of claim 1, further comprising a microphone electrically connected to the substrate.

15. The device of claim 1, further comprising a speaker electrically connected to the substrate.
