Abstract

Claims (49)

1. An earpiece comprising:

an earpiece housing defining an interior volume;

a speaker disposed within the interior volume; and

a pivot mechanism coupled to the earpiece housing and operable to enable the earpiece housing to rotate about both a roll axis and a yaw axis, the pivot mechanism comprising:

a bearing disposed within the earpiece housing;

a stem having a first end coupled to the headband and a second end coupled to the bearing enabling the stem to rotate about the yaw axis; and

first and second torsional springs disposed on opposite sides of the bearing and configured to oppose rotation of the stem about the roll axis.

2. The earpiece set forth in claim 1 wherein the pivot mechanism further comprises first and second mounting blocks disposed within the earpiece housing, and wherein the first torsional spring is coupled to the first mounting block and the second torsional spring is coupled to the second mounting block.

3. The earpiece set forth in claim 2 wherein the pivot mechanism further comprises a first fastener that couples the first mounting block to the earpiece housing and a second fastener that couples the second mounting block to the earpiece housing.

4. The earpiece set forth in claim 1 wherein the stem is coupled to the bearing by a threaded cap that allows the stem to twist about the yaw axis.

5. The earpiece set forth in claim 4 wherein the threaded cap defines a plurality of mechanical stops that limit a range of motion through which the stem can twist.

6. The earpiece set forth in claim 1 wherein the pivot mechanism further comprises a magnet and a sensor, the sensor configured to detect a change in a magnetic field of the magnet to detect rotation of the pivot mechanism about the roll axis.

7. The earpiece set forth in claim 1 wherein the pivot mechanism further comprises a magnet coupled to the stem and a sensor, the sensor configured to detect a change in a magnetic field of the magnet to detect rotation of the stem about the yaw axis.

8. The earpiece set forth in claim 1 wherein the pivot mechanism further comprises:

a first magnet and a first sensor, the first sensor configured to detect a change in a magnetic field of the first magnet to detect rotation of the pivot mechanism about the roll axis; and

a second magnet coupled to the stem and a second sensor, the second sensor configured to detect a change in a magnetic field of the second magnet to detect rotation of the stem about the roll axis.

9. An earpiece comprising:

an earpiece housing defining an interior volume;

a speaker disposed within the interior volume; and

a pivot mechanism coupled to the earpiece housing and operable to enable the earpiece housing to rotate, with respect to the headband, about both a roll axis and a yaw axis, the pivot mechanism comprising:

a bearing disposed within the earpiece housing;

a stem having a first end coupled to the headband and a second end coupled to the bearing by a threaded cap that enables the stem to twist about the yaw axis and defines a plurality of mechanical stops that limit the range of motion through which the stem can twist;

first and second mounting blocks disposed within the earpiece housing; and

first and second torsional springs disposed on opposite sides of the bearing and configured to oppose rotation of the stem about the roll axis, the first torsional spring coupled to the first mounting block and the second torsional spring coupled to the second mounting block.

10. The earpiece set forth in claim 9 wherein the pivot mechanism further comprises a magnet and a sensor, the sensor configured to detect a change in a magnetic field of the magnet to detect rotation of the pivot mechanism about the roll axis.

11. The earpiece set forth in claim 9 wherein the pivot mechanism further comprises a magnet coupled to the stem and a sensor, the sensor configured to detect a change in a magnetic field of the magnet to detect rotation of the stem about the yaw axis.

12. The earpiece set forth in claim 9 wherein the pivot mechanism further comprises:

a first magnet and a first sensor, the first sensor configured to detect a change in a magnetic field of the first magnet to detect rotation of the pivot mechanism about the roll axis; and

a second magnet coupled to the stem and a second sensor, the second sensor configured to detect a change in a magnetic field of the second magnet to detect rotation of the stem about the roll axis.

13. Headphones comprising:

a headband having first and second opposing ends;

a first earpiece pivotably coupled to the first end of the headband; and

a second earpiece pivotably coupled to the second end of the headband;

wherein each of the first and second earpieces comprises:

an earpiece housing defining an interior volume;

a speaker disposed within the interior volume; and

a pivot mechanism coupled to the earpiece housing and operable to enable the earpiece housing to rotate, with respect to the headband, about both a roll axis and a yaw axis, the pivot mechanism comprising:

a bearing disposed within the earpiece housing;

a stem having a first end coupled to the headband and a second end coupled to the bearing enabling the stem to rotate about the yaw axis; and

first and second torsional springs disposed on opposite sides of the bearing and configured to oppose rotation of the stem about the roll axis.

14. The headphones set forth in claim 13 wherein the pivot mechanism further comprises first and second mounting blocks disposed within the earpiece housing, and wherein the first torsional spring is coupled to the first mounting block and the second torsional spring is coupled to the second mounting block.

15. The headphones set forth in claim 14 wherein the pivot mechanism further comprises a first fastener that couples the first mounting block to the earpiece housing and a second fastener that couples the second mounting block to the earpiece housing.

16. The headphones set forth in claim 13 wherein the stem in each of the first and second earpieces is coupled to its respective bearing by a threaded cap that allows the stem to twist about the yaw axis.

17. The headphones set forth in claim 16 wherein the threaded cap in each of the first and second earpieces defines a plurality of mechanical stops that limit the range of motion through which its respective stem can twist.

18. The headphones set forth in claim 13 wherein the pivot mechanism in each of the first and second earpieces further comprises a magnet and a sensor, the sensor configured to detect a change in a magnetic field of the magnet to detect rotation of the pivot mechanism about the roll axis.

19. The headphones set forth in claim 13 wherein the pivot mechanism in each of the first and second earpieces further comprises a magnet coupled to the stem and a sensor, the sensor configured to detect a change in a magnetic field of the magnet to detect rotation of the stem about the yaw axis.

20. The headphones set forth in claim 13 wherein the pivot mechanism in each of the first and second earpieces further comprises:
