Abstract: A metal enclosure (5) is provided on a mobile phone. The mobile phone includes the enclosure, a rear cover (4), and an electronic component assembly. The enclosure is formed as a single piece, and comprises a top wall (51), a bottom wall (54), and a periphery wall (53) between the top and bottom walls. The walls cooperatively define an opening (57) at a rear end of the enclosure. The electronic component assembly is received in the enclosure, and the rear cover covers the opening. The mobile phone is thus completed. Because the enclosure has no joints, it is strong enough to withstand considerable shock. In addition, it provides excellent protection from EMI. Furthermore, it has a smooth attractive appearance.

Abstract: A cover structure (1) for a portable electronic device includes a metallic shell (10) and a plastic mounting frame (9) secured to the shell. The shell has a skirting panel (101) and a bottom panel (100) which cooperatively define a space (102) for receiving the mounting frame. The frame includes a U-shaped part (11) and an arcuate part (12) which are respectively dimensioned to closely fit onto corresponding end portions of the shell. Each of the U-shaped and arcuate parts includes at least one threaded post (112, 121) adapted for engaging with a corresponding fastening member (3), in order to fasten a printed circuit board (2) of the portable electronic device to the cover structure.
