In the singer's performance, the microphone is an important tool for accurate singing, and the principle of the microphone's sound will vary according to the type. This article will introduce the common "condenser microphone" and "moving coil microphone". microphone".
The sensitive sound-receiving properties of condenser microphones make it easy to record more sound details and are suitable for use in recording studios with good sound insulation. When the sound wave is introduced into the microphone, the sound wave will vibrate the two parallel metal sheets in front of the microphone. At this time, the tempered plastic diaphragm will vibrate with the sound wave, but the metal sheet at the back is fixed, and the capacitor formed by the distance between the two will be due to vibration. The voltage difference generated will be converted into different signals to generate sound. The difference between condenser microphones and other microphones is that they need to be powered on, and phantom power is often used on some recording interfaces.
The dynamic microphone is different from the highly sensitive condenser microphone. The dynamic microphone does not require additional power supply, so the sensitivity is low, and it is not easy to receive subtle audio. It is suitable for singing in public areas. The diaphragm of the moving coil microphone vibrates the diaphragm after receiving the sound wave, causing the coil wound on the magnet to vibrate back and forth. After the magnetic field changes, the current signal is generated.
Each different type of microphone has a different sound collection range and sensitivity. This sound collection range is called the "directivity" of the microphone. Microphones with different directivity have different uses, which can be used by singers or musicians. Choose from different venues.
After reading the above text introduction, do you have a preliminary understanding of how to choose a microphone?
