Abstract: The disclosed embodiments relate to a screw nut and an electronic device having the same. The screw nut is configured for fixation of a fastener. The screw nut includes an inner nut component, a cushioning component, and an outer nut component. The inner nut component has a screw hole portion configured for fixation of the fastener. The cushioning component is sleeved on the inner nut component. The outer nut component is sleeved on the cushioning component. The cushioning component is connected between the inner nut component and the outer nut component so that the inner nut component is movably connected to the outer nut component.

Abstract: A composite image device having image capturing, laser pointing, lighting and related functions in one includes a first perspective window, a second perspective window, a third perspective window, an image capturing module, laser source module, a light source module and a switchable light modulating module. The image capturing module captures ambient light through the first perspective window to generate digital image data. The laser source module emits a laser through the second perspective window. The light source module emits illuminating light through the third perspective window. The switchable light modulating module includes at least a light modulating gate and a switching device for moving the at least a light modulating gate to a position relatively parallel to the second or third perspective window to modulate the emitted laser or the emitted illuminating light.

Abstract: A keypad device for an electronic device includes a substrate, a first light-emitting device coupled to the substrate for generating a first colored light source, a second light-emitting device coupled to the substrate for generating a second colored light source different from the first colored light source, a first transparent board made of a translucent material of a first color for displaying a first symbol, a second transparent board made of a translucent material of a second color, for displaying a second symbol, and a transparent film deployed on the first transparent board and the second transparent board. The first color is a complementary color of the color of the first colored light source, and the second color is a complementary color of the color of the second colored light source.

Abstract: A protective shell for an electronic device is adapted to accommodate the electronic device. The electronic device includes a camera lens. The protective shell includes a shell body and a lens device. The shell body is adapted to accommodate the electronic device. The lens device is mounted on the shell body, and includes a plurality of lenses. The lens device is operable to move relative to the shell body such that a selected one of the lenses correspondingly overlaps one side of the camera lens of the electronic device to permit switching among different modes of use, thereby enabling the camera lens to have different functions, such as close-up, filtering, wide-angle, and polarizing functions.
