Abstract

Sound processors with light transmissive seals and systems including such sound processors are disclosed.

Claims

1. A method of operating a sound processor having a housing, the method comprising the step of:

transmitting visible light that is representative of an operational aspect of the sound processor through a seal that is compressed by the sound processor housing such that the visible light passing through the compressed seal is visible from outside of the sound processor housing.

2. A method as claimed in claim 1, wherein the seal is located between a portion of the housing and a portion of a port.

3. A method as claimed in claim 1, wherein the seal is located between a portion of the housing and a portion of a button.

4. A method as claimed in claim 1, further comprising the step of:

emitting visible light that is representative of an operational aspect of the sound processor into the seal from a location within the housing.

5. A method as claimed in claim 1, further comprising the steps of:

emitting visible light of a first color into the seal from a location within the housing in response to a first operational aspect of the sound processor; and

emitting visible light of a second color into the seal from a location within the housing in response to a second operational aspect of the sound processor.

6. A sound processor, comprising:

a housing defining an exterior;

sound processor circuitry within the housing;

a seal formed at least in part from substantially translucent elastomeric material, the seal being compressed by the sound processor housing and positioned such that at least a portion of the substantially translucent elastomeric material is visible from outside the housing; and

a light emitter carried within housing that directs light into the substantially translucent elastomeric material such that the light is visible at the housing exterior.

7. A sound processor as claimed in claim 6, wherein the seal is compressed between a portion of the housing and a portion of a structure associated with the housing exterior.

8. A sound processor as claimed in claim 7, wherein the structure associated with the housing exterior comprises a port.

9. A sound processor as claimed in claim 7, wherein the structure associated with the housing exterior comprises a button.

10. A sound processor as claimed in claim 7, wherein

the structure associated with the housing exterior includes a cylindrical surface;

the housing includes a cylindrical surface; and

the seal includes a cylindrical portion.

11. A sound processor as claimed in claim 6, wherein the seal is formed from at least substantially transparent elastomeric material.

12. A sound processor as claimed in claim 6, wherein

the housing is formed from relatively hard material;

and

the at least substantially translucent elastomeric material is softer than the relatively hard material.

13. A sound processor as claimed in claim 12, wherein the at least substantially translucent elastomeric material has a hardness of about 40-80 Shore A.

14. A sound processor as claimed in claim 6, wherein the seal includes a compressed protrusion.

15. A sound processor as claimed in claim 6, wherein the light emitter comprises an LED.

16. A sound processor, comprising:

a housing defining an exterior;

a device, accessible from the exterior of the housing, carried by the housing such that a gap is defined between a portion of the housing and a portion of the device;

sound processor circuitry within the housing;

a light emitter carried within the housing; and

means, located within the gap and associated with the light emitter, for sealing the gap against the ingress of moisture while transmitting light through the gap to the exterior of the housing.

17. A sound processor as claimed in claim 16, wherein the device comprises a port.

18. A sound processor as claimed in claim 16, wherein the device comprises a button.

19. A sound processor as claimed in claim 16, wherein the light emitter comprises an LED.
