Technical field

The present disclosure relates to the field of communications technologies, and in particular, to an acousto-optic transmission component and a mobile terminal.

Background technique

With the increasing popularity of mobile terminals, users have higher and higher requirements for the experience of mobile terminals. On the one hand, users prefer multi-functional mobile terminals in terms of functional experience, and on the other hand, users tend to have thin and light mobile terminals. Multi-functional mobile terminals require the use of multiple assemblies, which occupy the assembly space of the fuselage, while the thin and light mobile terminals tend to have smaller assembly space, thus allowing more installations in smaller assembly spaces. Accessories are of great significance for the development of multi-functional mobile terminals.

In the mobile terminal of the related art, a first cover (for example, a receiver cover) for guiding sound and a second cover (for example, a fill light cover) for guiding light are generally provided, and the two covers are The arrangement is generally as shown in FIG. 1 (wherein the first cover is shown at 11 and the second cover is shown at 12), so that the total width of the two covers needs to be occupied as shown in FIG. L1. It is not difficult to see that the cover body in the mobile terminal in the related art has a problem that the assembly space is large.
