Abstract

Disclosed herein is a mobile device comprising a plate; the plate being adapted to accommodate a printed circuit board; a ring bonded to the plate; a seal disposed between the ring and the plate, the plate and ring and seal forming a mid-plate structure; wherein the seal comprises a platform; and a housing unit bonded to the platform.

Claims

1. A mobile device comprising:

a plate;

the plate being adapted to accommodate a printed circuit board;

a ring bonded to the plate via a plurality of attachment points, wherein the attachment points partially define a plurality of void-spaces between the ring and the plate;

a seal disposed within the void-spaces, the plate and ring and seal forming a mid-plate structure;

wherein the seal comprises a platform; and

a housing unit bonded to the platform.

2. The mobile device of claim 1, wherein the ring and the plate include steel, and wherein the ring is bonded to the plate with a weld.

3. The mobile device of claim 1, wherein the plate is rectangular having two long sides, and wherein the ring is rectangular having two long sides, and wherein one of the long sides of the ring is bonded to one of the long sides of the plate.

4. The mobile device of claim 1, wherein the platform is a first platform, the seal further comprising a second platform, wherein the first platform and the second platform face mutually opposed directions;

the mobile device further comprising a display unit bonded to the second platform.

5. The mobile device of claim 1, wherein the seal comprises a polymer and wherein the housing unit comprises a polymeric rim, and wherein the polymeric rim of the housing unit is bonded to the platform of the seal with laser welding.

6. The mobile device of claim 1, where the seal comprises an elastomer.

7. The mobile device of claim 4, where the bond between the housing unit and the first platform and the bond between the display unit and the second platform are adhesive bonds.

8. The mobile device of claim 1, where the bond between the housing unit and the platform is accomplished with laser welding.

9. The mobile device of claim 1, where the housing unit comprises a metal or a polymer.

10. The mobile device of claim 1, where the mobile device is a smart phone, a tablet, a handheld computer, a mobile internet device, a wearable computer, a personal digital assistant, a handheld gaming console, a personal navigation device, a smart watch, a head mounted display, a calculator or a portable media player.

11. The mobile device of claim 1, further comprising one or more of a mobile communication module, a wireless internet module, a short range communication module, a location information module, an audio-visual input unit comprising a camera and/or a microphone;

a sensing unit comprising a proximity sensor; and

a memory.
