Abstract

A remote speaker microphone includes a housing having a bezel defining an outer surface. The remote speaker microphone further includes a toggle switch lever that rocks back and forth relative to the bezel. The remote speaker microphone further includes a bezel opening through which the toggle switch lever extends at the outer surface. The bezel and the toggle switch lever define a predetermined gap within the bezel opening and within which the toggle switch lever rocks. The bezel, the bezel opening, and the toggle switch lever together form an ice crushing region in response to rocking the toggle switch lever.

First claim

We claim:

1. A remote speaker microphone comprising:
a housing having a bezel defining an outer surface;
a toggle switch lever configured to rock back and forth relative to the bezel; and
a bezel opening through which the toggle switch lever extends at the outer surface, the bezel and the toggle switch lever defining a predetermined gap within the bezel opening and within which the toggle switch lever rocks,
wherein the bezel, the bezel opening, and the toggle switch lever together form an ice crushing region in response to rocking the toggle switch lever;
wherein the bezel opening is a through opening extending through the bezel, wherein the bezel includes a concave surface that defines a portion of the through opening, and wherein the toggle switch lever includes a convex surface spaced by the predetermined gap from the concave surface of the bezel along an entirety of the concave surface, such that the predetermined gap is an open, unfilled gap along the entirety of the concave surface;
wherein the toggle switch lever defines a neutral axis when the toggle switch lever is not rocked and is in a natural, default position, wherein the neutral axis passes centrally through the bezel opening and passes centrally through the toggle switch lever, wherein the bezel includes a first sloped surface and a second sloped surface extending from the first sloped surface, wherein the first and second sloped surfaces are sloped at different angles relative to one another, and are each sloped at an oblique angle relative to the neutral axis.

2. The remote speaker microphone of claim 1 , wherein the predetermined gap is between 0.2 mm-0.3 mm and forms part of the ice crushing region.

3. The remote speaker microphone of claim 1 , wherein the toggle switch lever includes a first portion disposed outside of and exterior to the through opening, the first portion configured to be physically contacted and rocked by a user, the toggle switch lever further having a second portion disposed within the through opening, wherein the second portion is configured to rock with the first portion.

4. The remote speaker microphone of claim 1 , wherein the convex surface of the toggle switch lever is configured to rotate and slide adjacent the concave surface of the bezel when the toggle switch lever is rocked.

5. The remote speaker microphone of claim 1 , wherein a portion the convex surface of the toggle switch lever extends past the concave surface of the bezel.

6. The remote speaker microphone of claim 1 , wherein the first sloped surface is directly adjacent the concave surface of the bezel.

7. The remote speaker microphone of claim 1 , wherein the first sloped surface extends between a first edge and a second edge of the bezel, wherein the second edge is disposed between the first edge and the concave surface of the bezel, and wherein the first sloped surface is angled such that the bezel opening is larger at the first edge than at the second edge.

8. The remote speaker microphone of claim 7 , wherein the first sloped surface forms part of the ice crushing region.

9. The remote speaker microphone of claim 1 , wherein the first and second sloped surfaces form part of the ice crushing region.

10. The remote speaker microphone of claim 1 , wherein the first and second sloped surfaces are each planar.

11. The remote speaker microphone of claim 1 , wherein the first sloped surface is planar.

12. The remote speaker microphone of claim 1 , wherein the first sloped surface extends entirely around the bezel opening.

13. The remote speaker microphone of claim 1 , further comprising a toggle support element disposed interior to the bezel, and a keypad and flex element disposed interior to the toggle support element, wherein the keypad is coupled to the flex element with adhesive.

14. The remote speaker microphone of claim 13 , wherein a portion of the toggle switch lever is configured to press against the keypad when the toggle switch lever is rocked.

15. The remote speaker microphone of claim 13 , wherein the bezel, the toggle switch lever, the toggle support element, and the keypad are each part of a top module of the remote speaker microphone, wherein the toggle switch lever is exposed to an environment outside of the remote speaker microphone, and wherein the top module is a water-sealed sub-assembly of the remote speaker microphone.

16. The remote speaker microphone of claim 1 , wherein the convex surface is configured to be spaced by the predetermined gap from the concave surface of the bezel along the entirety of the concave surface at all times.

17. The remote speaker microphone of claim 1 , wherein the concave surface is one continuous concave surface.

18. A remote speaker microphone comprising:
a housing having a bezel defining an outer surface;
a toggle switch lever configured to rock back and forth relative to the bezel; and
a bezel opening through which the toggle switch lever extends at the outer surface, the bezel and the toggle switch lever defining a predetermined gap within the bezel opening and within which the toggle switch lever rocks,
wherein the bezel includes a first sloped surface that defines a portion of the bezel opening and a second sloped surface extending from the first sloped surface that also defines a portion of the bezel opening, wherein the first and second sloped surfaces are sloped at different angles relative to one another, and wherein the first sloped surface is disposed between the concave surface and the second sloped surface, wherein the first sloped surface extends between a first edge and a second edge of the bezel, and wherein the second sloped surface extends between the first edge and a third edge of the bezel, wherein the bezel opening is larger at the third edge than at the first edge, and is larger at the first edge than at the second edge.

19. The remote speaker microphone of claim 18 , wherein both the first sloped surface and the second sloped surface each extend entirely around the bezel opening.

20. A remote speaker microphone comprising:
a housing having a bezel defining an outer surface;
a toggle switch lever configured to rock back and forth relative to the bezel; and
a bezel opening through which the toggle switch lever extends at the outer surface, the bezel and the toggle switch lever defining a predetermined gap within the bezel opening and within which the toggle switch lever rocks,
wherein the bezel, the bezel opening, and the toggle switch lever together form an ice crushing region in response to rocking the toggle switch lever;
wherein the bezel opening is a through opening extending through the bezel, wherein the bezel includes a concave surface that defines a portion of the through opening, and wherein the toggle switch lever includes a convex surface spaced by the predetermined gap from the concave surface of the bezel along an entirety of the concave surface, such that the predetermined gap is an open, unfilled gap along the entirety of the concave surface;
wherein the predetermined gap is between 0.2 mm-0.3 mm and forms part of the ice crushing region.
