Abstract

Improved housings for electronic devices are disclosed. In one embodiment, an electronic device housing can have one or more outer members (e.g., exposed major surfaces), such as front or back surfaces, that are formed of glass. The one or more glass surfaces can be part of outer member assemblies that can be secured to other portions of the electronic device housing. In other embodiments, apparatus, systems and methods for robustly attaching a cover portion of an electronic device to a bottom portion, e.g., a housing portion, of the electronic device are described. The electronic device can be portable and in some cases handheld.

Claims

1. An electronic device enclosure, comprising:

an outer periphery member defining a side surface for the electronic device enclosure; and

a front cover assembly including (i) a front cover member defining an outer surface that is entirely exposed, and (ii) an interface member, wherein;

the interface member comprises a peripheral portion surrounding an open central portion, the peripheral portion including or coupled to at least one attachment member;

the peripheral portion of the interface member is secured to a peripheral portion of an inner surface of the front cover member, the inner surface of the front cover member being opposite the outer surface; and

the at least one attachment member is used to secure the front cover assembly to an inner surface of the outer periphery member.

2. The electronic device enclosure as recited in claim 1, wherein the electronic device enclosure comprises:

a protective side member positioned adjacent sides of the front cover member.

3. The electronic device enclosure as recited in claim 1, wherein the protective side member comprises a compound including at least polyarylamide.

4. The electronic device enclosure as recited in claim 1, wherein the protective side member comprises a polymer having a Coefficient of Thermal Expansion (CTE) less than or equal to about 50 millimeters/meter/.degree. C.

5. The electronic device enclosure as recited in claim 1, wherein the thickness of the protective side member is not more than about 1 mm.

6. The electronic device enclosure as recited in claim 1, wherein the protective side member comprises a polymer having a Coefficient of Thermal Expansion (CTE) less than or equal to about 35 millimeters/meter/.degree. C.

7. The electronic device enclosure as recited in claim 1, wherein the at least one attachment member is a tab extending outward from the peripheral portion away from the glass member.

8. The electronic device enclosure as recited in claim 7, wherein the tab includes a threaded screw hole.

9. The electronic device enclosure as recited in claim 8, wherein the threaded screw hole is configured to receive a screw used to secure the front cover assembly with respect to the electronic device enclosure.

10. The electronic device enclosure as recited in claim 8, wherein the threaded screw hole is configured to receive a screw used to secure the front cover assembly with respect to the outer periphery member.

11. The electronic device enclosure as recited in claim 1, wherein the front cover member comprises a glass member.

12. The electronic device enclosure as recited in claim 1, wherein:

the front cover member has exposed edges;

the front cover assembly includes a protective side member, the protective side member being provided against and around side surfaces of the front cover member; and

the protective side member does not extend over the exposed outer surface of the front cover member.

13. The electronic device enclosure as recited in claim 12, wherein:

the front cover member comprises a glass member; and

the protective side member comprises polymer strengthened with glass fibers.

14. The electronic device enclosure as recited in claim 1, wherein the attachment member is integral with or attached to the interface member.

15. The electronic device enclosure as recited in claim 14, wherein the attachment member is configured to secure the front cover assembly with respect to the electronic device enclosure.

16. An assembly for an electronic device, comprising:

a cover subassembly comprising;

a frame having a peripheral portion defining an open central region and having a plurality of attachment members protruding therefrom; and

a transparent member defining an outer surface that is entirely exposed and an inner surface that is opposite the outer surface;

a housing part including a plurality of receptacles located on an inner surface of the housing part and configured to capture the plurality of attachment members when the cover subassembly is coupled to the housing part; and

at least one electronic component arranged within an inner volume defined by at least the housing part, wherein;

the peripheral portion of the frame supports and is secured to a peripheral region of an inner surface of the transparent member; and

the transparent member is secured relative to the housing part by the plurality of attachment members being captured in the plurality of receptacles.

17. The assembly of claim 16, wherein the cover subassembly is in substantially direct contact with the housing part when the plurality of attachment members are captured in the corresponding plurality of receptacles.

18. The assembly of claim 16, wherein:

the transparent member comprises a glass member;

the frame extends around a periphery to the glass member; and

the glass member is adhered to the frame.

19. The assembly of claim 16, wherein:

the cover subassembly is at least partially formed from a plastic material;

the at least one attachment member is formed from a metal; and

the at least one attachment member being insert molded into the plastic material.

20. An electronic device enclosure, comprising:
