[0105] The light source 32 may be provided with one or more. In this embodiment, a plurality of light sources 32 are provided, each of which corresponds to a light-transmitting boss 27; and the light source 32 is a led bulb.

[0106] The structure of the mobile terminal of the present invention does not need to be secondary processing for button injection molding, and the light-emitting button assembly can be implemented. On the basis of light transmission, the cost of the workpiece is low and the production efficiency is improved.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the scope of the invention, and the equivalent structure or equivalent flow transformation made by the specification and the drawings of the present invention may be directly or indirectly applied to other related The technical field is equally included in the scope of patent protection of the present invention.
