Display robot broadcasting device capable of keeping normal broadcasting

Abstract

The invention provides a display robot broadcasting device capable of keeping normal broadcasting. Broadcaster comprising a broadcaster shell, sound transmission holes which are uniformly distributedare formed in the mesh enclosure; springs are installed below the mesh enclosure, an air bag is installed on the right side of the fixed plate, a movable plate is fixedly connected to the right side of the air bag, a magnetic block is fixedly connected to the right side of the movable plate, an electromagnet is fixedly installed in the broadcaster shell, a rotating plate is rotatably connected tothe interior of the broadcaster shell and located below the switch, and a pressing plate is fixedly connected to the bottom of the mesh enclosure. When the sound transmission hole is blocked; mesh enclosure weight-variable downward movement, the pressing plate extrudes the rotating plate to rotate and contact the switch; the electromagnet has magnetism after being powered on, the movable plate ispushed to quickly move leftwards to compress the air bag under the action of like repulsive force of the magnet, air in the air bag is sprayed to the sound transmission holes to be blown and brushed,the function of automatic cleaning after the mesh enclosure is blocked is achieved, and the problem that sound transmission of the broadcasting device is blocked due to the fact that the mesh enclosure is blocked is solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent display robots, in particular to a broadcasting device for a display robot that maintains normal broadcasting. Background technique [0002] With the development of science and technology, the functions of intelligent robots are becoming more and more perfect. In various exhibitions or exhibition halls, various intelligent display robots have also appeared for corporate publicity, important information release, intelligent online services, etc. It can not only introduce and broadcast information to people, but also interact with people. Because of its powerful function, beautiful appearance and smart appearance, it has been very popular in the market in recent years. [0003] In order to facilitate people to listen to the information, the announcer of the display robot is generally set at the top, but the crowds in the exhibition are generally large, the air environment is poor, and many peopl...

AI Technical Summary

Problems solved by technology

[0003] In order to facilitate people to listen to the information, the announcer of the display robot is generally set at the top, but the crowds in the exhibition are generally large, the air environment is poor, and many people, especially children, will touch the display robot out of curiosity, It is easy to cause the outside of the display robot to be dirty. Although the outside of the speaker is equipped with a protective grille, the grille is also prone to being blocked by impurities. When the grille on the speaker is blocked, the internal sound cannot be transmitted normally. come out and affect people's listening effect
