Classroom broadcasting device based on artificial intelligence

Abstract

The classroom broadcasting device based on artificial intelligence comprises a sound box shell, a separation net is arranged at an opening in the left side of the sound box shell, the upper side and the lower side of a trigger mechanism are movably connected with amplification mechanisms, and the left sides of the amplification mechanisms are movably connected with cleaning mechanisms. When the sound equipment works, a paper bowl continuously vibrates, continuously touches an arc-shaped convex part, drives an abutting plate to move left and right, cooperates with the meshing effect of a rack plate connected to the right side of the abutting plate and a gear, and coaxially and fixedly connects the gear with a larger diameter and a turntable with a smaller diameter, so that the force applied to the gear by the rack plate is amplified; it is guaranteed that a piston rod connected with the connecting rod has large force to push and pull a piston plate to move along the inner wall of a piston pipe, positive pressure and negative pressure are continuously generated in the piston pipe, air is pumped and blown into a vertical hole, and dust in the vertical hole and dust in a horizontal hole are discharged through flowing of airflow; therefore, the purpose of automatically cleaning the separation net is achieved.

Description

technical field [0001] The invention relates to the technical field of classroom broadcasting, in particular to an artificial intelligence-based classroom broadcasting device. Background technique [0002] In order to facilitate the school to play various announcements and meet the needs of the listening test, wall-mounted speakers are generally installed on the walls of the classroom. This type of speaker occupies a small space and has a good audio playback effect, which can meet the broadcasting needs of most classrooms. [0003] For the wall-mounted speakers installed in the classroom, under the erosion of chalk chips and dust, the screen installed in the front of the speaker tends to accumulate a lot of dust, which makes the speaker screen not clean enough, and also affects the sound quality of the audio played by the speaker. In addition, The chalk chips and dust entering the interior of the speaker may corrode the internal circuit of the speaker and affect the service ...
