Abstract

A satellite microphone assembly formed by a base housing a microphone and a volume control electronics and an outer ring coupled with the base and rotatable about the base. The outer ring includes a center aperture having an actuatable button to toggle mute/unmute of the microphone disposed therein. A rotational sensor is supported by the base and configured to detect a rotation of the outer ring and to output information about a direction and a degree of rotation of the outer ring to the volume control electronics, thereby causing a rotation of the outer ring to affect a volume of a speaker.

Claims

1. A satellite microphone assembly comprising:

a base housing a microphone and a volume control electronics;

an outer ring coupled with the base and rotatable about the base, the outer ring having a center aperture and a sidewall configured to be engaged by a user so that a user can rotate the ring;

an actuatable button disposed within the center aperture of the outer ring to toggle mute/unmute of the microphone; and

an rotational sensor supported by the base, the rotational sensor configured to detect a rotation of the outer ring and to output information about a direction and a degree of rotation of the outer ring to the volume control electronics, and cause a rotation of the outer ring to affect a volume of a speaker.

2. The satellite microphone assembly of claim 1, further comprising an inner ring coupled with the base, the outer ring disposed over the inner ring and rotatable relative to the inner ring and the base, wherein the inner ring and the base are stationary.

3. The satellite microphone assembly of claim 2, wherein the inner ring has one or more protrusions inwardly extending toward the center aperture and the actuatable button has one or more corresponding protrusions engaged with the one or more protrusions, thereby securing the actuatable button stationary relative to the outer ring.

4. The satellite microphone assembly of claim 3, wherein the one or more protrusions and the one or more corresponding protrusions are arranged to reduce backlash.

5. The satellite microphone assembly of claim 1, wherein the actuatable button includes a microphone port communicatively coupled with the microphone housed in the base.

6. The satellite microphone assembly of claim 1, wherein the rotational sensor is an accelerometer detecting rotational speed of the outer ring relative to the base.

7. A rotational assembly, comprising:

a base a control electronics;

an inner ring securely coupled with the base, the inner ring having a center aperture;

an outer ring disposed over the inner ring and rotatable about the relative to the inner ring, the outer ring having a center aperture, the center aperture of the outer ring having a larger diameter than the center aperture of the inner ring;

a button disposed within the center aperture of the outer ring; and

a rotational sensor supported by the base, the rotational sensor configured to detect a rotation of the outer ring relative to the base, the rotational sensor outputting information about a direction and a degree of rotation of the outer ring to the control electronics.

8. The rotational assembly of claim 7, wherein the inner ring has one or more protrusions inwardly extending toward the center aperture and the button has one or more corresponding protrusions engaged with the one or more protrusions, thereby securing the button stationary relative to the outer ring.

9. The rotational assembly of claim 8, wherein one or the one or more protrusions of the inner ring and the one or more corresponding protrusions of the button are grooves and the other of the one or more protrusions of the inner ring and the one or more corresponding protrusions of the button are protrusions, thereby forming a tongue and groove arrangement.

10. The rotational assembly of claim 7, wherein the rotational sensor is an accelerometer detecting rotational speed of the outer ring relative to the base.

11. The rotational assembly of claim 10, wherein the accelerometer detecting movement of the base signals the control electronics to disable one or more features of the button.

12. The rotational assembly of claim 7, wherein the button is an actuatable button and includes a biasing element configured to return the actuatable button to a first position after removal of an actuation force.

13. The rotational assembly of claim 7, wherein the button is a touch sensitive button requiring no physical response.

14. The rotational assembly 13, wherein the inner ring includes one or more apertures configured to couple the inner ring with the base and the one or more apertures are formed in one or more protrusions extending toward the center aperture and the engagable with one or more corresponding protrusions formed on the button.

15. A satellite microphone system comprising:

a base communication device having at least one microphone and at least one speaker, the base communication device coupled with at least one satellite microphone assembly,

the satellite microphone assembly comprising;

a base housing a microphone and a volume control electronics;

an outer ring coupled with the base and rotatable about the base, the ring having a center aperture and a sidewall configured to be engaged by a user so that a user can rotate the ring;

an actuatable button disposed within the center aperture of the ring to toggle mute/unmute of the microphone; and

an rotational sensor supported by the base, the rotational sensor configured to detect a rotation of the cylinder and to output information about a direction and a degree of rotation of the cylinder to the volume control electronics, and cause a rotation of the cylinder to affect a volume of the speaker.

16. The satellite microphone system of claim 15, further comprising an inner ring coupled with the base, the outer ring disposed over the inner ring and rotatable relative to the inner ring and the base, wherein the inner ring and the base are stationary.

17. The satellite microphone system of claim 16, wherein the inner ring has one or more protrusions inwardly extending toward the center aperture and the actuatable button has one or more corresponding protrusions engaged with the one or more protrusions, thereby securing the actuatable button stationary relative to the outer ring.

18. The satellite microphone system of claim 17, wherein the one or more protrusions and the one or more corresponding protrusions are arranged to reduce backlash.

19. The satellite microphone system of claim 15, wherein the actuatable button includes a microphone port communicatively coupled with the microphone housed in the base.

20. The satellite microphone system of claim 15, wherein the rotational sensor is an accelerometer detecting rotational speed of the outer ring relative to the base.
