Why does a reporter have to add a Mao Mao to his microphone?

With this sound, it will be clearer and the effect will be different. The microphone is transmitted to the diaphragm of the microphone through the vibration of sound, which pushes the magnet inside to form a changing current, and the changing current is sent to the sound processing circuit behind for amplification.

The blowout preventer is placed in front of the microphone, for example, some pronunciations, such as B and P, will play a role when there is a strong jet sound. If your original microphone is not a professional microphone, it is not needed.

The speaker system is designed to ensure sound horizontal transmission in all directions. By using distributed echo cancellation and noise cancellation technology, it can automatically eliminate the sound echo and noise that make the listener tired, and keep the original clean and clear sound.

In the 20th century, the microphone changed from resistance type to inductance and capacitance type, and gradually developed a large number of new microphone technologies, including aluminum tape, moving coil and other microphones, as well as condenser microphones and electret microphones which are widely used at present.

Precautions for microphone maintenance:

1. Pay attention to the push and pull of the microphone buttons and push them into position. If there is a lot of noise in use, it may be caused by improper push-pull of the switch or poor contact. The correct way is to push and pull the switch again. If the contact is not good, it should be repaired as soon as possible.

2. If the conference microphone or wireless microphone is not used for a long time, the battery should be removed and installed when it is used. If there is intermittent sound during use, it may be caused by insufficient battery power, and a new battery should be replaced in time.

3. When not in use, store the microphone in a dry and clean place, and avoid storing and using it in a high temperature and high humidity place, so as not to affect the sensitivity and timbre of the microphone.
