Abstract

Improved housings for electronic devices are disclosed. An electronic device housing can make use of at least one outer member (e.g., cover) that can be aligned, protected and/or secured with respect to other portions of the housing for the electronic device. 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. Protective sides can be provided in some embodiments to protect the edges of the one or more glass surfaces so as to dissipate impact forces and thus reduce damage to the electronic device housing. 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. According to one aspect, adjoining surfaces of electronic device housings can be mounted or arranged such that adjoining surfaces are flush to a high degree of precision. 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;

an internal structure secured to an inner surface of the outer periphery member, the internal structure offset from front and back planar boundaries of the outer periphery member; and

a front cover assembly placed and secured adjacent the front planar boundary of the outer peripheral boundary, thereby providing a front surface for the electronic device enclosure, the front cover assembly including a front cover member and a protective side member, the protective side member being provided against and around the sides of the front cover member.

2. An electronic device enclosure as recited in claim 1, wherein a top edge of the protective side member is substantially flush with a top surface of the front cover.

3. An electronic device enclosure as recited in claim 2, wherein the flushness of the top edge of the outer peripheral boundary is substantially flush with the top surface of the front cover is controlled such that any deviation in flushness is not more that 60 micrometers.

4. An electronic device enclosure as recited in claim 1, wherein the internal structure provides structural stiffness for the electronic device enclosure.

5. An electronic device enclosure as recited in claim 4, wherein the internal structure comprises an internal platform.

6. An electronic device enclosure as recited in claim 5, wherein a first plurality of electrical device components are provided in a top region of the internal platform, and a second plurality of electrical device components are provided in a back region of the internal platform.

7. An electronic device enclosure as recited in claim 1, wherein the outer periphery member comprises metal, and wherein the front cover member comprises glass.

8. An electronic device enclosure as recited in claim 1, a back cover assembly placed adjacent the back planar boundary, thereby providing a back surface for the electronic device enclosure, and wherein the back cover assembly comprises glass.

9. An electronic device enclosure as recited in claim 1, wherein the internal structure comprises at least one of metal and plastic.

10. An electronic device enclosure, comprising:

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

an internal structure secured to an inner surface of the outer periphery member, the internal structure providing structural support for the electronic device enclosure;

an attachment member; and

a front cover assembly placed and secured adjacent the front planar boundary of the outer peripheral boundary using at least the attachment member, which forms a front surface for the electronic device enclosure, the front cover assembly including a front cover member and a protective side member, the front cover member having exposed edges, and the protective side member being provided against and around the exposed edges of the front cover member.

11. An electronic device enclosure as recited claim 10, wherein the electronic device housing comprises:

means for securely mounted the front cover assembly to the internal structure or the outer periphery member.

12. An electronic device enclosure as recited in claim 10, wherein the protective side member comprises polyarylamide.

13. An electronic device enclosure as recited in claim 10, wherein the protective side member comprises a polymer having a Coefficient of Thermal Expansion (CTE) less than or equal to about 50 millimeters/meter/°

C.

14. An electronic device enclosure as recited in claim 10, wherein the thickness of the protective side member is not more than about 1 mm.
