The invention discloses an information display and release
system, relates to the technical field of combined audio-visual display, and solves the problem that the
sound quality of a propaganda
sound box is influenced by the loss of high-
frequency sound caused by limitation of air flow passing through a
loudspeaker box body due to the fact that dust in holes of a
sound box mesh
enclosure is affected with damp, agglomerated and difficult to dredge. Stand columns are fixedly installed at the two ends of the
bulletin board, an LED rolling display strip is installed on the upper side of the
bulletin board, the LED rolling display strip is fixedly connected with the stand columns, and a
loudspeaker box body is fixedly installed on the sides, away from the
bulletin board, of the stand columns. According to the
sound box mesh
enclosure cleaning device, the cleaning mechanism is installed, a
brush in the cleaning mechanism can reciprocate left and right in the rotating process, and bristles of the
brush can penetrate through holes in the sound box mesh
enclosure in the left-right reciprocating process, so that dust accumulated in the holes of the sound box mesh enclosure can be conveniently pushed out, and the purpose of automatically cleaning the holes of the sound box mesh enclosure is achieved.
