An enclosure (200) is provided. The enclosure (200) includes a substrate (1) and composite film layer (2) coated onto the substrate (1). A thickness of the composite film layer (2) gradually decreases or increases along a first direction (X), and a difference between film thicknesses of any two regions arranged along the first direction (X) on the composite film layer (2) is less than or equal to 350 nanometers, so that the enclosure (200) presents a gradient color of a wavelength ranging from 400 nanometers to 760 nanometers. A mobile terminal (100) having the enclosure (200) and a sputter coating apparatus (300) are further disclosed.
A mobile terminal, comprising an enclosure, applied to a mobile terminal, wherein the enclosure comprises a substrate and a composite film layer coated onto the substrate, a thickness of the composite film layer gradually decreases or increases in a first direction, wherein the composite film layer comprises a first region, a second region, and a third region, the first region is adjacent to the second region, the second region is adjacent to the third region, and a difference between average film thicknesses of any two adjacent regions is less than or equal to 350 nanometers, wherein a difference between an average film thickness of the first region and an average film thickness of the second region is a first value, a difference between the average film thickness of the second region and an average film thickness of the third region is a second value, and a ratio of the first value to the second value is within a range of 0.5 to 2.0;
