What are condenser microphones and what are their features
ntroduction to condenser microphone:
Condenser microphone, also known as condenser microphone, is a microphone that converts sound signals into electrical signals.
The capacitor Miley uses the charge discharge principle of the capacitor. The vibration of the sound drives a plate (ultra-thin metal film) of the capacitor. The vibration of the plate changes the distance between the two plates, and then changes the capacitance. When the capacitance becomes larger, the power source charges the capacitor; when the capacitance becomes small, the capacitor discharges, causing current in the circuit and converting the sound signal into an electrical signal.
Features of condenser microphone:
1) It has a very wide frequency response
Vibrating membrane is the main component of microphone to sense sound and convert it into electrical signal. The material and mechanism design of vibrating membrane determine the sound quality of microphone.
Because the vibration film of the condenser microphone can be made of extremely thin material, and the induced sound pressure can be directly converted into audio signal, so the frequency response bass can be extended to the ultra-low frequency below 10Hz, and the treble can easily reach the ultrasonic wave of tens of kHz.
2) It has super high sensitivity
Because there is no voice coil load on the vibrating membrane, it can adopt extremely thin design. Therefore, it not only has excellent frequency response, but also has excellent sensitivity. It can sense extremely weak sound wave and output the clearest, delicate and accurate original sound.
3) It has the characteristics of resistance to fall and impact
When using the microphone, it is hard to avoid failure or abnormality due to accidental drop and collision. As the capacitive sound head is composed of light plastic parts and solid light metal shell, the impact force of falling to the ground is small, and the failure rate of damage is low.
