Abstract

A handheld computing device is disclosed. The handheld computing device includes an enclosure having structural walls formed from a ceramic material that is radio-transparent.

Claims

1. A portable computing device capable of wireless communications, the portable computing device comprising:

an enclosure that surrounds and protects the internal operational components of the portable computing device, the enclosure including a structural wall formed from a ceramic material that permits wireless communications therethrough.

2. The portable computing device as recited in claim 1 wherein the portable computing device is capable of radio frequency communications and wherein the structural wall formed from a ceramic material is radio-transparent.

3. The portable computing device as recited in claim 1 wherein the ceramic material is zirconia.

4. The portable computing device as recited in claim 1 wherein the ceramic material is alumina.

5. The portable computing device as recited in claim 1 wherein the enclosure includes a tube like main body that is extruded in its entirety with the ceramic material.

6. The portable computing device as recited in claim 1 wherein the portable computing device is a handheld computing device.

7. The portable computing device as recited in claim 6 wherein the handheld computing device is a cell phone.

8. The portable computing device as recited in claim 6 wherein the handheld computing device is a media player.

9. A portable computing device, comprising:

an enclosure that surrounds and protects the internal operational components of the portable computing device, the enclosure including a structural wall formed from a ceramic material.

10. The portable computing device as recited in claim 9 wherein the ceramic material is zirconia.

11. The portable computing device as recited in claim 9 wherein the enclosure includes multiple structural walls formed the ceramic material.

12. The portable computing device as recited in claim 9 wherein a significant portion of the entire enclosure is formed a ceramic material.

13. The portable computing device as recited in claim 9 wherein the enclosure includes an extruded tube of the ceramic material, and end caps that close the ends of the extruded tube of ceramic material.

14. A handheld computing device, comprising:

a seamless tube formed from a ceramic material and extending along a longitudinal axis, the seamless tube having a first open end and a second open end opposite the first open end, the elongated seamless tube defining an internal lumen which is sized and dimensioned for insertion of operational components of the handheld computing device.

15. The handheld computing device as recited in claim 14 wherein the lumen includes internal rails for guiding the operational components to their desired position within the lumen.

16. The handheld computing device as recited in claim 14 wherein the seamless enclosure has a substantially planar front surface, the planar front surface being configured to present a user interface sub system of the handheld computing device, the open ends being configured to receive the user interface sub system therethrough during assembly of the handheld computing device.

17. The handheld computing device as recited in claim 16 wherein the lumen includes internal rails for guiding the operational components to their desired position within the lumen, and wherein the internal rails being configured to locate the user interface sub system in its desired position relative to the planar front surface of the enclosure during assembly of the handheld device.

18. The handheld computing device as recited in claim 16 wherein the user interface sub system includes a display and a touch pad.

19. The handheld computing device as recited in claim 14 wherein the ceramic material is zirconia.

20. The handheld computing device as recited in claim 14 further comprising end caps at the first and second ends of the seamless tube, the end caps and seamless tube working together to fully surround the internal operational components of the handheld computing device.

21. The handheld computing device as recited in claim 14 wherein the handheld computing device is a music player.

22. A portable computing device capable of wireless communications, the portable computing device comprising:

an enclosure that surrounds and protects the internal operational components of the portable computing device, the enclosure including a structural wall formed from a material other than plastic that permits wireless communications therethrough; and

an internal antenna disposed inside the enclosure.

23. The portable computing device as recited in claim 22 wherein the portable computing device is capable of radio frequency communications and wherein the structural wall is formed from a ceramic material that is radio-transparent.

24. The portable computing device as recited in claim 23 wherein the ceramic material is zirconia.

25. The portable computing device as recited in claim 22 wherein the structural wall constitutes a substantial portion of the entire enclosure.

26. The portable computing device as recited in claim 22 wherein the structural wall constitutes one or more walls of the entire enclosure.

27. The portable computing device as recited in claim 22 wherein the structural wall constitutes two or more walls of the entire enclosure.

28. The portable computing device as recited in claim 22 wherein the enclosure only includes a main body and a pair of end caps, the structural wall being at least a portion of the main body.

29. The portable computing device as recited in claim 28 wherein the structural wall constitutes the entire main body.
