Abstract

A portable electronic device is disclosed in which an LCD (140) and a PCB (130) of the device are mounted on to first and second opposed sides of an internal frame. The internal frame has a stiffness chosen to suppress the distortion of the LCD and vibration of the PCB (140) resulting from a shock. A battery (170) is mounted onto the PCB (140) such that the internal frame supports the LCD (140) on one side and the PCB (130) with the battery mounted on it on the opposite side.

Claims

1. A portable electronic device comprising:

a housing;

a frame internal of the housing;

a printed circuit board and a display mounted on and supported by the frame, the frame having a stiffness and/or a spring constant higher than that of the circuit board or the display.

2. A portable electronic device as claimed in claim 1, wherein the printed circuit board is mounted on a first side of the frame and the display is mounted on the second opposing side of the frame.

3. A portable electronic device as claimed in claim 1, further comprising a battery mounted on the frame.

4. A portable electronic device as claimed in claim 3, wherein the battery is mounted onto the frame by being affixed to the printed circuit board.

5. A portable electronic device as claimed in claim 4, wherein the battery has a plurality of sides of differing surface area and the side of largest surface area is affixed to the printed circuit board.

6. A portable electronic device as claimed in claim 4 wherein the battery is of flat or pancake-like dimensions

7. A portable electronic device as claimed in claim 1 wherein the frame forms a backbone for the components mounted thereon.

8. A portable electronic device as claimed in claim 1 wherein the frame is formed from metal.

9. A portable electronic device as claimed in claim 8 wherein the metal is a magnesium alloy.

10. A portable electronic device as claimed in claim 1 wherein the frame is formed from a non-metallic material.

11. A portable electronic device as claimed in claim 10 wherein the frame is formed from Fibre Reinforced Plastic or Carbon Fibre Reinforced Plastic.

12. A portable electronic device as claimed in claim 1 wherein the display is a liquid crystal display.

13. A portable electronic device comprising a housing;

a printed circuit board and a battery disposed within the housing, wherein the battery is attached to the printed circuit board to provide support for the printed circuit board.

14. A device as claimed in claim 13 further comprising a frame, to which the circuit board is attached.

15. A device as claimed in claim 14 wherein the frame and battery are attached to opposed sides of the circuit board.

16. A device as claimed in claim 14 wherein the frame is stiffer than the circuit board.
