Abstract

Example implementations relate to ferromagnetic covers. For instance, in an example housing can include a bezel including first opening extending through a recess included in the bezel, a first magnet and a second magnet in an internal volume of the housing, and a ferromagnetic cover disposed in the recess and magnetically coupled to the first magnet and the second magnet, where the ferromagnetic cover includes a second opening to obscure a viewing portion of the first opening with the continuous portion when the ferromagnetic cover is positioned adjacent to a first side surface of the recess.

First claim

What is claimed:

1. A housing comprising:
a bezel including first opening extending through a recess included in an outer surface of the bezel;
a first magnet and a second magnet in an internal volume of the housing;
a ferromagnetic cover disposed in the recess and coupled to the bezel solely via a magnetic coupling to the first magnet and the second magnet, wherein the ferromagnetic cover includes a second opening to expose a viewing portion of the first opening and a third opening, wherein an entirety of an outer surface of the ferromagnetic cover is co-planar with the outer surface of the bezel; and
a visual indicator disposed in the recess at a location that is visible via the third opening when the ferromagnetic cover is adjacent to a side surface of the recess.

2. The housing of claim 1 , wherein each surface of the ferromagnetic cover comprises a mechanical connectionless surface.

3. The housing of claim 1 , wherein the ferromagnetic cover has a total length that is less than a corresponding total length of the recess.

4. The housing of claim 1 , wherein the first magnet is positioned on a first side of the first opening and the second magnet is positioned on a second side of the first opening that is opposite the first side of the first opening.

5. The housing of claim 4 , wherein the first side of the first opening and the second side of the first opening are disposed along a substantially horizontal plane extending along the length of the recess.

6. The housing of claim 4 , wherein the housing further comprises a third magnet positioned on the first side of the first opening and a fourth magnet positioned on the second side of the first opening.

7. The housing of claim 1 , wherein the bezel has a uniform thickness along an entirety of a perimeter of the bezel.

8. The housing of claim 1 , wherein the ferromagnetic cover has a thickness from 50 to 500 microns, and wherein the bezel has a thickness from 500 to 1200 microns.

9. The housing of claim 1 , wherein the ferromagnetic cover further comprises a continuous portion to obscure the viewing portion when the ferromagnetic cover is positioned adjacent to the side surface of the recess.

10. An electronic device comprising:
a camera including a lens; and
a housing including:
a bezel including defining a portion of an internal volume of the housing and including a first opening extending through a recess included in an outer surface of the bezel;
a first magnet and a second magnet in the internal volume of the housing; and
a visual indicator;
a ferromagnetic cover coupled to the bezel solely via a magnetic coupling to the first magnet and the second magnet, the ferromagnetic cover including: a second opening to expose the lens when the ferromagnetic cover is positioned adjacent to a side surface of the recess; and
a continuous portion to obscure the lens, wherein an entirety of an outer surface of the ferromagnetic cover is co-planar with the outer surface of the bezel, and wherein the lens is recessed a distance from the ferromagnetic cover protect the lens from contacting the ferromagnetic cover; and
a third opening, wherein the visual indicator is visible via the third opening when the ferromagnetic cover is positioned at the side of the recess.

11. The electronic device of claim 10 , wherein the camera is a shutterless camera.

12. The electronic device of claim 10 , wherein the visual indicator further comprises a nonpowered visual indicator.

13. The electronic device of claim 12 , wherein the nonpowered visual indicator is located in the recess.

14. The electronic device of claim 13 , wherein the nonpowered visual indicator is located in the recess at a location that is visible via the third opening in the ferromagnetic cover when the ferromagnetic cover is positioned at the side of the recess.
