Headset with reciprocating microphone support
A headset has a microphone boom slidably disposed in a sleeve of the headset with a microphone being mounted on the distal end of the boom. The boom is prevented from rotating in the sleeve.
1. An assembly, comprising:
at least one headband;
at least a first support structure defined by the headband;
at least one elongated boom slidably supported by the first support structure and comprising a distal end on which is mounted at least one microphone;
a first ear cup coupled to the first support structure to pivot about a first axis of the first ear cup and a second axis of the first ear cup;
at least a second support structure defined by the head band; and
at least a second ear cup coupled to the second support structure to pivot about a first axis of the second ear cup and a second axis of the second ear cup,
wherein the first axis of the first ear cup passes through a center of the first ear cup from a first circumferential edge of the first ear cup to a second circumferential edge of the first cup that is diametrically opposite the first edge of the first ear cup,
the second axis of the first ear cup passes through the center of the first ear cup from a third edge of the first ear cup to a fourth edge of the first cup that is diametrically opposite the third edge of the first ear cup, and
the first ear cup cannot rotate about a third axis that is normal to the first and second axes of the first ear cup.
2. The assembly of claim 1 , wherein the boom cannot rotate within the first support structure.
3. The assembly of claim 1 , wherein the boom is slidably disposed within the first support structure.
4. The assembly of claim 1 , wherein the first support structure is unitarily made with the crown portion of the head band.
5. The assembly of claim 1 , wherein the first support structure is elongated and is oriented generally perpendicular to the crown portion.
6. The assembly of claim 1 , comprising structure that prevents withdrawing the boom completely out of the first support structure.
7. The assembly of claim 1 , wherein the first support structure comprises a hollow portion forming a sleeve for accommodating the boom.
8. The assembly of claim 1 , wherein the boom comprises a crimped or enlarged proximal end within the first support structure preventing removal of the boom from the first support structure.
9. The assembly of claim 1 , wherein the at least one microphone is located outside of the first support structure.
10. The assembly of claim 1 , wherein the first support structure comprises a stop preventing motion of the at least one microphone into the first support structure.
11. The assembly of claim 1 , wherein the first support structure comprises an anti-rotation rib configured to receive a portion of the boom.
12. The assembly of claim 1 , wherein the first ear cup is coupled to the first support structure by a hinge comprising a ball and a pair of pivot plates.
13. The assembly of claim 12 , wherein the pair of pivot plates comprises a disc-shaped pivot plate allowing back-and-forth motion of the first ear cup about the first axis.
14. The assembly of claim 13 , wherein the pair of pivot plates comprises a racetrack-shaped pivot plate lying against the disc-shaped pivot plate.
15. The assembly of claim 12 , wherein the hinge comprises a wedge-shaped anti-rotation mechanism that fits into a complementary opening in a first of the pair of pivot plates.
16. The assembly of claim 1 , wherein the headband comprising a first support structure defining the sleeve.
17. The assembly of claim 16 , wherein the first ear cup is coupled to the headband by a hinge located at the first support structure.
18. The assembly of claim 16 , wherein the at least one microphone is located outside of the first support structure.
19. The assembly of claim 16 , wherein the first support structure comprises a stop preventing motion of the at least one microphone into the first support structure.
20. The assembly of claim 16 , wherein the first support structure comprises an anti-rotation rib configured to receive a portion of the boom.
21. The assembly of claim 16 , wherein the hinge comprises a ball and a pair of pivot plates.
22. The assembly of claim 21 , wherein the pair of pivot plates comprises a disc-shaped pivot plate allowing back-and-forth motion of the first ear cup about the first axis.
23. The assembly of claim 22 , wherein the pair of pivot plates comprises a racetrack-shaped pivot plate lying against the disc-shaped pivot plate.
24. The assembly of claim 21 , wherein the hinge comprises a wedge-shaped anti-rotation mechanism that fits into a complementary opening in a first of the pair of pivot plates.
25. A headset comprising:
a headband;
an elongated microphone support;
a microphone on the microphone support;
a sleeve defined by the headband in which the elongated microphone support is disposed for reciprocating motion relative to the sleeve; and
at least a left ear cup coupled to the headband to pivot about both a first and a second axis extending diametrically across the left ear cup, wherein the left ear cup cannot rotate about a third axis that is perpendicular to the first and second axes.
26. The headset of claim 25 , wherein the microphone support is movable from an extended configuration, in which the microphone is distanced from the sleeve, and a retracted configuration, in which the microphone is closer to the sleeve than in the extended configuration.
27. The headset of claim 25 , wherein the elongated microphone support comprises a gooseneck boom.
28. The headset of claim 25 , wherein the microphone support defines a cross-sectional shape that is not completely round.
29. The headset of claim 28 , wherein owing to the cross-sectional shape of the microphone support, at least one flat surface of the microphone support rides against a surface of the sleeve to prevent rotation of the microphone support within the sleeve.
