Abstract

Embodiments relate generally to systems and methods for containing a potentiometer within a wheel for use in an earmuff. An earmuff (for use with a headset) may comprise a housing configured to contain the internal elements of the earmuff; one or more sound producing elements located within the earmuff; a wheel at least partially exposed by an opening in the housing, configured to be rotated by a user; a potentiometer located within the wheel configured to detect and measure the rotation of the wheel by the user; and a processor configured to control the sound intensity output from the one or more sound producing elements based on receiving the detection from the potentiometer.

Claims (48)

1. An earmuff for use with a headset, the earmuff comprising:

a housing;

one or more speakers located within the earmuff;

a wheel at least partially exposed by an opening in the housing, configured to be rotated by a user, wherein the wheel comprises an internal cavity, wherein the wheel is enclosed within a wall;

a potentiometer located within the internal cavity and configured to detect and measure the rotation of the wheel by the user;

a cover,

wherein the cover comprises a lubricating material at an interface between the wheel and the cover configured to facilitate the rotation of the wheel with respect to the cover,

wherein the cover secures the potentiometer within the internal cavity;

a processor configured to control the sound intensity output from the one or more speakers based on receiving the detection from the potentiometer; and

one or more forbidden areas, wherein a first forbidden area is defined by a space between a horizontal portion of the wall, a contact surface and a bottom housing.

2. The earmuff of claim 1 , wherein the potentiometer comprises a rotor.

3. The earmuff of claim 2 , wherein the wheel comprises a shaft configured to interface with the rotor to cause the rotor to rotate with the rotation of the wheel.

4. The earmuff of claim 2 , wherein the potentiometer further comprises one or more terminals extending from the potentiometer to the processor.

5. The earmuff of claim 1 , wherein the wall surrounding the wheel is configured to seal the interior of the earmuff while exposing at least a portion of the wheel.

6. The earmuff of claim 1 , wherein the potentiometer comprising a diameter of approximately 15 millimeters.

7. The earmuff of claim 1 , wherein the wheel comprises a rotation stop located on the interior of the wheel configured to limit the rotation of the wheel by interacting with a portion of the potentiometer.

8. The earmuff of claim 1 , wherein the housing comprises one or more stabilizing walls configured to hold at least a portion of the wheel in place relative to the housing, while allowing the wheel to rotate with respect to the housing.

9. A headset comprising:

a first earmuff comprising:

a housing configured to contain the internal elements of the earmuff;

one or more sound producing elements speakers located within the first earmuff;

a wheel at least partially exposed by an opening in the housing, configured to be rotated by a user, wherein the wheel comprises an internal cavity, wherein the wheel is enclosed within a wall;

a potentiometer located within the internal cavity configured to detect and measure the rotation of the wheel by the user;

a cover,

wherein the cover comprises a lubricating material at an interface between the wheel and the cover configured to facilitate the rotation of the wheel with respect to the cover,

wherein the cover secures the potentiometer within the internal cavity;

a processor configured to control a sound intensity output from the speakers based on receiving the detection from the potentiometer;

one or more forbidden areas, wherein a first forbidden area is defined by a space between a horizontal portion of the wall, a contact surface and a bottom housing;

a second earmuff; and

a band connecting the first earmuff to the second earmuff.

10. The headset of claim 9 , further comprising one or more wire connection elements connecting the first earmuff to the second earmuff.

11. The headset of claim 10 , wherein the second earmuff comprises one or more speakers, and wherein the processor is configured to control the sound intensity output from the one or more speakers of the second earmuff.

12. The headset of claim 9 , wherein the potentiometer comprises a rotor, and wherein the wheel comprises a shaft configured to interface with a rotor to cause the rotor to rotate with the rotation of the wheel.

13. The headset of claim 9 , wherein the wall is configured to seal the interior of the first earmuff while exposing at least a portion of the wheel.

14. An earmuff for use with a headset, the earmuff comprising:

a housing;

one or more speakers located within the earmuff;

a wheel at least partially exposed by an opening in the housing, configured to be rotated by a user,

wherein the wheel comprises an internal cavity, wherein the wheel is enclosed within a wall;

wherein the wall seals an interior of the earmuff while exposing at least a portion of the wheel;

a potentiometer located within the internal cavity configured to detect and measure the rotation of the wheel by the user;

a processor configured to control the sound intensity output from the one or more speakers based on receiving the detection from the potentiometer; and

one or more forbidden areas, wherein a first forbidden area is defined by a space between a horizontal portion of the wall, a contact surface and a bottom housing.

15. The earmuff of claim 14 , wherein the potentiometer comprises a rotor.

16. The earmuff of claim 15 , wherein the wheel comprises a shaft configured to interface with the rotor to cause the rotor to rotate with the rotation of the wheel.

17. The earmuff of claim 14 , wherein the potentiometer further comprises one or more terminals extending from the potentiometer to the processor.

18. The earmuff of claim 14 , further comprises a cover, wherein the cover comprises a lubricating material at an interface between the wheel wherein the cover secures the potentiometer within the internal cavity, and wherein the cover is configured to facilitate the rotation of the wheel with respect to the cover.

19. The earmuff of claim 14 , wherein the wall surrounding the wheel is configured to seal the interior of the earmuff while exposing at least a portion of the wheel.
