Maybe some people think that it's just to use the microphone, just point it at the mouth and use it directly? Actually otherwise, let me tell you the correct way to use the microphone.
First, keep the distance between the microphone and the mouth 5-10 cm, and the distance between the microphone and the mouth should be 5-10 cm. Too close, the close-talking effect will occur, and the sound is very light when it is too far away.
Second, do not hold two wireless microphones together. If the two microphones are close together, their mutual harmonics will be mutually modulated and disturbed, which will seriously affect the transmission acceptance and sound quality.
Third, don’t hold your hand on the head of the microphone. Some microphones have a certain directivity. Grasping the hand on the screen will seriously damage the frequency response. It will also cause aggregation and feedback due to the aggregation effect of the palm. And other phenomena.
Fourth, don’t hold the microphone’s antenna transmission position tightly with your hands. For handheld microphones, the transmission circuit and antenna are located at the lower part of the microphone. When we hold them with our hands, the transmission power will be greatly attenuated and the reception effect will be affected.
Fifth, prevent the microphone from directly facing the speaker. If the microphone directly faces the speaker, a closed loop is formed, and positive feedback vibration will occur.
