Abstract: Methods for treating aluminum for providing a tactile sensation of surface softness are provided. In this regard, a representative method includes: providing an aluminum component having a surface; exposing the surface to a first media blasting; exposing the surface to a second media blasting; and, after the second media blasting, chemical etching and anodizing the surface.

Abstract: An electronic device includes a housing, a light emitting module, a light sensor and a lens. The light emitting module is disposed inside the housing and configured to emit a light out of the housing. The light sensor is disposed inside the housing and configured to receive an environmental light from outside of the housing. The lens, coupled with the housing, includes a first transparent portion, a second transparent portion and an opaque portion. The first transparent portion allows the light to be emitted out of the housing. The second transparent portion allows the environmental light to pass through, so that the light sensor receives the environmental light. The opaque portion is disposed between the first transparent portion and the second transparent portion. The first transparent portion, the second transparent portion and the opaque portion are integrated into a whole and made of the same material.
