Description

Technical Field

[0001] The utility model relates to the technical field of audio matrix devices, in particular to a multifunctional digital audio matrix. Background Art

[0002] The audio matrix device is a complete video surveillance system device that integrates video switching, audio switching, alarm management, follow-up control, and IP network optional control. Any video signal connected to the matrix can be displayed on the monitor you want to watch, and you can also use the control keyboard that comes with the matrix to realize the front-end camera with controllable functions. We can place it in the middle of the conference room desktop in the conference room, and use the rear wiring port to connect the laptops carried by multiple participants in a unified manner to realize matrix file sharing.

[0003] For example, a multifunctional digital audio matrix with publication number CN201922332342.4 includes a main body; a guide seat is welded on the left side of the top surface of the main body shell, ..., wherein the upper pulley is connected to the conveyor belt set on the inner side of the above-mentioned handwheel by belt transmission, and the upper pulley and the lower pulley are also connected by synchronous transmission through the conveyor belt. Through a series of belt transmission structures, two upper and lower nozzle structures are installed in linkage on the rear side of the device. The two nozzle structures are laterally distributed on the rear side of the audio device to form an upper and lower blowing structure. The two pipes are elastically supported on the rear USB plug board through a bending spring assembly, and linkage control is achieved through a series of belt transmission mechanisms on the front side. Therefore, after the forward air source pipe connected to the two nozzles is connected to the external pressure air source, the gas will enter the rear side of the device, and the area of ​​the rear USB wiring port where dust is more likely to be stored will be blown and dust removed in an up and down swinging manner. Therefore, the structural defect that the rear part of the device is installed on the wall and the rear area is narrow and inconvenient for cleaning the rear side can be solved.

[0004] Although the above patent can solve the structural defect that after the rear part of the equipment is installed on the wall, it is inconvenient to clean the rear side due to the narrow rear area, but the user needs to manually rotate the nozzle during the cleaning process, which is not only troublesome to operate but also has a small cleaning range, so that the cleaning effect does not achieve the expected effect.
