Abstract

A housing of a computing device, such as a computer, laptop computer, cellular phone, personal digital assistant (PDA), tablet computer, electronic reader or e-reader, or other mobile device constructed using a combination of a metal material and a lightweight core material. The housing includes a front housing component including a display and a rear housing coupled to the front housing component with an internal side of the rear housing facing the front housing. The rear housing component includes a core material and a structural material coupled to the core material at strategic locations. For example, the structural material may be located around a periphery of the rear housing, around connection ports of the electronic device, and diagonally across the external side to provide strength and stiffness to the rear housing.

First claim

What is claimed is:

1. A housing component for an electronic device, the housing component comprising:
an internal face;
an external face;
a core material extending across a plane of the housing component, wherein a strength of the core material is weaker in a first direction than in a second direction; and
a structural material layered on at least one portion of the core material to provide structural support in the first direction to the core material, wherein the structural material:
is layered on the core material around at least one connection port of the housing component, and
is absent from an area of the core material to reduce interference of a transmitting antenna of the electronic device.

2. The housing component of claim 1 , wherein:
the structural material is comprised of at least one of aluminum, titanium, magnesium, stainless steel, nickel, tin, chromium, cobalt, or copper; and
the core material is a fiber based material having strength properties corresponding to a direction of orientation of axes of fibers of the fiber based material.

3. The housing component of claim 1 , wherein the structural material is layered on the at least one portion of the core material toward the external face of the housing component.

4. The housing component of claim 1 , wherein the structural material is layered on the at least one portion of the core material toward the internal face of the housing component.

5. The housing component of claim 1 , wherein the structural material is layered on the at least one portion of the core material at a periphery of the housing component.

6. The housing component of claim 1 , wherein the structural material is layered on the at least one portion of the core material to form a pattern having areas absent the structural material that increase in surface area from proximal to a periphery of the housing component in a direction toward a center of the housing component.

7. The housing component of claim 1 , wherein the structural material is layered on the at least one portion of the core material from a periphery of the housing component toward a center of the housing component and decreases in thickness from the periphery toward the center.

8. The housing component of claim 1 , wherein the structural material is layered on the at least one portion of the core material at a location corresponding to a position of a component of the electronic device to protect the component when housed by the housing component.

9. A method of making a component for an electronic device, comprising:
forming a housing component comprising:
a core material extending across a plane of the housing component, wherein a strength of the core material is weaker in a first direction than in a second direction,
a first structural material layered on the core material toward an external face of the housing component, the first structural material providing structural support to the core material, and
a second structural material layered on the core material toward an internal face of the housing component, the second structural material providing structural support to the core material; and

removing a portion of at least one of the first or second structural materials to reduce a weight of the housing component but maintain structural support of the core material in the first direction.

10. The method of claim 9 , wherein the forming step includes plating the first and second structural materials on the core material, and the core material is a fiber based material having strength properties corresponding to a direction of orientation of axes of fibers of the fiber based material.

11. The method of claim 9 , wherein the removing step includes removing the portion of the first structural material from a central area of the housing component, leaving a peripheral portion of the first structural material on the housing component.

12. The method of claim 9 , wherein the removing step includes removing the portion of the second structural material from a central area of the housing component, leaving a peripheral portion of the second structural material on the housing component.

13. The method of claim 9 , wherein the removing step includes removing the portion of both of the first and second structural materials at substantially a same location.

14. The method of claim 9 , wherein the removing step includes removing the portion of the first structural material from a central area of the housing component, leaving a connection portion of the first structural material around a connection port of the housing component.

15. The method of claim 9 , wherein the removing step includes removing the portion of the first structural material forming a pattern having areas absent the first structural material that increase in surface area from proximal to a periphery of the housing component in a direction toward a center of the housing component.

16. The method of claim 9 , wherein the removing step includes removing the portion of the second structural material from a central area of the housing component, leaving the second structural material at a location corresponding to a position of a component of the electronic device to protect the component when housed by the housing component.
