Sound box cover

The facemask of sound box includes at least a set of mesh. A certain angle between central line of the set of mesh and vertical reference line passing through the facemask of sound box is tilted, being applied to sound box, the facemask makes sound emitted from loudspeakers apart from mutually very near go different directions when sound passes the facemask. Thus, sound from different loudspeakers generates difference of time and angle when being transferred to human ears. The sound box or acoustics system possess larger width degree of sound field, and better separation sense of sound.
