Abstract: The present disclosure provides a metal-resin composite and a preparation method. The metal-resin composite includes a metal substrate; a porous resin layer formed on the metal substrate; a plastic layer formed on the porous resin layer; and a pore passage. The pore passage passes through the porous resin layer and extends inside the metal substrate, and the plastic layer fills in the pore passage to bond with the metal substrate.

Abstract: Disclosed are a composite material, a shell for a mobile device, their manufacturing methods, and a mobile device. The composite material includes: a first metal substrate (100); a first resin fiber plate (200) disposed on an upper surface of the first metal substrate; an antenna layer (300) disposed on an upper surface of the first resin fiber plate; a second resin fiber plate (400) disposed on an upper surface of the antenna layer; and a second metal substrate (500) disposed on an upper surface of the second resin fiber plate.

Abstract: A key-press structure comprises a transparent substrate, a plurality of characters formed inside the transparent substrate thereby forming a plurality of keys, and a touch control member disposed on the surface of the transparent substrate such that each of the keys is operable to sense a touch event.

Abstract: A method of forming a shell of an electrical device comprises the steps of: conforming a sheet assembly to at least a part of an outer configuration of the shell, wherein the sheet assembly includes a sheet and a photo-cured coating on one side of the sheet, the coating forming a predetermined pattern; injecting a base material into an injection mold for forming the shell after placing the sheet assembly inside the injection mold, with the side of the sheet on which the photo-cured coating is formed facing a cavity of the injection mold; and removing the sheet assembly from the shell.

Abstract: A shell for an electronic device is provided. The shell includes a shell body and a pattern layer disposed on an outer surface of the shell body and formed by a curable material. The shell also includes a transparent protective layer disposed on an outer surface of the pattern layer.

Abstract: In one aspect, a key-press structure comprises a frame and a plurality of keys disposed in said frame. Said frame comprises a main portion and two reflecting portions. The main portion has two opposite sides and the two reflecting portions are disposed on the two opposite sides of the main portion, respectively. Said reflecting portion has a reflective surface facing toward the main portion. Said keys are made of a transparent material, and the keys comprise characters formed on the internal surface of said keys. In another aspect, a method of preparing a key-press structure comprises forming a frame that includes a main portion and two reflecting portions. The reflecting portions each have a reflective surface. The main portion has two opposite sides that is connected to the two reflecting portions. The method further comprises forming characters on the internal surface of a plurality of keys, and disposing said keys in the main portion of the frame.

Abstract: A coated plastic sheet comprises a transparent plastic sheet having a top and bottom surface, and a first film on the top surface and covering less than all of the top surface, thereby creating at least one uncovered area. At least a portion of the first film has a first metallic luster on its exposed surface. The coated plastic sheet also comprises a second film on the bottom surface. At least a portion of the second film is visible through the uncovered area of the sheet, wherein the second film presents a second metallic luster through the uncovered area.
