Which Is Best? A Dynamic Microphone or A Condenser Microphone

  The microphone plays a very important role in the entire recording mixing process. It is the number one person who converts voice into radio waves. In other words, if your radio is in trouble here, even if you have the best mixer, The effects can't be saved. There are hundreds of kinds of brands and types of microphones on the market. How do you find a pair of microphones that are suitable for your use?
  Dynamic microphone and Condenser microphone design principle
  According to the internal structure of the microphone can be divided into two kinds of dynamic microphone and condenser microphone, the former principle is to use sound waves to promote the diaphragm, and then shock film driven coil, the use of changes in magnetic lines have a weak voltage. This microphone is the most common microphone on the market, the general arena or hand-held microphone is the majority of this, it does not need external power supply can be inserted directly into the speaker system pronunciation, because this microphone is more portable , The frequency response is not bad, so the popularity is high;
  Condenser microphone are superior to dynamic microphones in terms of sensitivity and extended high-frequency (and sometimes low-frequency) response.
  This is related to how the Condenser microphone needs to first convert the sound signal into current. In general, condenser microphone diaphragms are very thin, and they are susceptible to vibrations due to sound pressure, causing a corresponding change in voltage between the diaphragm and the diaphragm backplate. And this voltage change will be followed by preamplifier multiples of amplification, and then converted into sound signal output.

  BY-PVM50 Condenser Microphone
  The BOYA BY-PVM50 is a stereo X/Y condenser microphone with compact body and lightweight for easy use, which specially designed for DSLR cameras, Camcorders, Audio recorders etc.

condenser microphone

  The "preamplifier" used here refers to an amplifier built into a microphone, not what we commonly refer to as "pre-amp", the preamplifier that comes with the console or interface. Due to the very small area of ​​the Condenser microphone diaphragm, its response to low- or high-frequency sound signals is very sensitive. Most Condenser microphone are capable of accurately capturing the sound signals that many people simply can not hear.

  In contrast, the working principle of dynamic microphone is much simpler. It mainly produces sound signals through the movement of the conductor in a magnetic field. In fact, the generation of the dynamic sound signal of the microphone is mainly accomplished by the continuous movement of the wire coil connected to the diaphragm in accordance with the change of the sound pressure in the magnetic field. Because of the relatively large volume of the moving part, the dynamic microphone is inferior to the Condenser microphone in terms of the response frequency range (mainly high-frequency part), sensitivity, and instantaneous response capability.
