2. An apparatus according to

claim 1

, wherein the cover is moulded from a polymer material.

3. An apparatus according to

claim 2

, wherein the polymer material is a self-skinning foam polymer material.

4. An apparatus according to

claim 1

, wherein the cover has an aperture revealing a display.

5. An apparatus according to

claim 4

, including a manually operable electronic input device, wherein said input device is located within said aperture.

6. An apparatus according to

claim 1

, including a manually operable electronic input device, wherein said input device is located within an aperture in said cover.

7. An apparatus according to

claim 1

, including a user interface assembly, comprising a window and the keys of a keypad, and a printed circuit board, having electronic components including a display device mounted thereto, wherein the user interface assembly is glued to the printed circuit board such that the window is aligned with the display device and the whole is substantially embedded within the cover.

8. A portable radio device according to

claim 1

.

9. A mobile telephone according to

claim 8

.

10. A portable electronic apparatus comprising a one-piece cover.

11. An apparatus according to

claim 10
