Let's introduce the microphone knowledge! 1. Electret: It is used for voice chat, which is equivalent to telephone communication or small meetings. The function is to be able to hear clearly, without restoration and lack of frequency. The pickup head is generally a coil wound on a small ring-shaped magnet. The structure is very simple. It is often used on voice headphones, or a very simple microphone with a small black head on the gooseneck. However, note that the electret is actually a kind of capacitor, which belongs to Construct a class of simple capacitors. This type of microphone is not suitable for recording work. It is suitable for communication with chat software such as skype, QQ, YY, etc. It is basically a little stronger than a telephone or mobile phone, and the price is generally lower.

2. Large-film capacitors: microphones commonly used in recording studios or studios, generally three directivity (respectively - cardioid: commonly used to record vocals, recent speech, etc.; figure-8 direction: the left and right sides of the range pickup, suitable for one The left and right sides of the microphone chorus or speak at the same time; omnidirectional: the range is relatively wide, there is no direction, suitable for recording indoor instruments, bands, etc.) The pickup head is generally a large diaphragm, which looks like a diaphragm inside the microphone. Different shapes, but the pickup part is relatively large, relatively flat, many brands, most of them are relatively expensive, professional use, the better the microphone, the higher the degree of restoration, the more the voice of the voice is required to be comprehensive and stable.

3. Small-film capacitors: Microphones commonly used in stage plays or interviews with reporters, or recording musical instruments, have special directivity. Compared with large-film capacitors, small-film capacitors are commonly oriented in a straight line, which can pick up sound in one direction. Generally, it can also be used for recording, but the pickup distance is much farther than that of the large diaphragm, and the shape is relatively thin and cylindrical.
