[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] When working, when the staff needs to use the equipment, the staff places the wireless microphone base 1 on the table and uses the fixing suction cup 5 to fix the wireless microphone base 1 to the table. When the staff needs to move while giving a speech, the first electric push rod 2 is activated. The first electric push rod 2 drives the wireless microphone base 1 to extend out of the interior of the wireless microphone base 1. The staff can directly hold the handle 3 to move the equipment. The anti-slip rubber ring 4 increases the friction between the staff's palm and the handle 3, making it more convenient for the staff to hold the handle 3.

[0036] When the equipment is not in use, start the electromagnet 6, and the staff will place the dust cover 9 on top of the electromagnet 6 to seal the microphone 7 and microphone 8 to prevent dust. Start the electric rotating rod 12, which will drive the rotating blade 13 to rotate and ventilate the inside of the dust cover 9. The filter screen 11 can filter and purify the outside air when it enters the dust cover 9, preventing impurities in the air from entering the dust cover 9 and adhering to the side walls of the microphone 7 and microphone 8, which would cause dust and impurities to enter the microphone 7 and microphone 8 and damage them.

[0037] The wind sensor 14 can monitor the air intake speed of the filter 11 in real time. When the wind sensor 14 detects that the air intake speed of the filter 11 has slowed down, the wind sensor 14 controls the second electric push rod 15 to start. The second electric push rod 15 drives the cleaning soft brush 16 to brush the filter 11, so as to prevent dust in the air from adhering to the top of the filter 11, causing the filter 11 to be blocked by dust in the air and affecting the ventilation efficiency of the filter 11.
