1, the capacitive microphone mainly produces sound signals through the vibration of the metal film caused by sound waves to produce different capacitances. There are two main types of condenser microphones, one is powered by No.5 battery, and the other is powered by 48V phantom power supply. The latter is mainly used in studios and recording studios with fixed shelves. Capacitor wheat is characterized by high clarity and sensitivity, full and rich sound quality but not turbid, but the disadvantage is that the sensitivity is too high, which is not suitable for places with high noise;
3. The moving-coil microphone mainly generates sound signals through the continuous movement of the coil closely connected with the diaphragm in the magnetic field according to the sound pressure change, without power supply. It has some advantages, such as simplicity, low noise and strong anti-noise ability, but it also has some disadvantages, such as low volume, stuffy sound, poor clarity and sensitivity.
