wireless microphone

　　Many of the friends have lavalier wireless microphone in their hands. Similarly, they often suffer headaches for lavalier microphones. Headaches are mainly concentrated in the use of lavalier microphone , the volume can not push up, slightly push a little bigger, it is prone to whistling. If an equalizer is used to pull the howling point, it will not be howling, and the microphone's voice will not be heard, but will be thin and scattered. 　　Why does this happen? First of all, an important reason why the microphone is whistling is that the microphone can receive the sound from the speaker. As long as the microphone can receive the sound from the speaker, the path for positive feedback is established. As long as the path of positive feedback is available, as long as the sound from the speakers is large enough, positive feedback self-excited, that is, howling will occur. 　　See here, many friends will ask: Why is the lavalier microphone on the stage, behind the speakers, but al

　　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 syste

　　There are three types of microphones: dynamic microphones, condenser microphones, and ribbon microphones. How to select a microphone is not simply to see which high price represents good quality, only the most suitable microphone is the best microphone. Most know what kind of microphone is best, first look at the occasion, then look at the demand, let's take a look at their respective advantages and disadvantages of the three microphones. 　　The sensitivity of the dynamic microphone is not high enough. Compared with the Condenser microphone , it cannot pick up more details, but it is also not easy to pick up the ambient noise. It is very suitable for use on the stage and it is not easy to produce feedback and howling. Another advantage of insensitivity is that the sound pressure level is large, that is, it can tolerate very loud sounds without sonic booming. For example, picking up snare drums at close range on the stage, the sound of excellent drummers is very loud.

Condenser microphone sound quality and sensitivity are basically better than dynamic microphone, condenser microphone can record more harmonic elements and more details, so the professional recording studio basically use condenser microphone recording. However, if you have a bad environment, such as a noisy environment and an echo in the room, using the condenser microphone will have the opposite effect. It is easy to record noise and echo, which is a terrible thing. Therefore, if the environment is not good, using a dynamic microphone is more appropriate than a Condenser microphone , and even a headset electret is more appropriate. In addition, the near-speaking effect characteristics of dynamic microphones are relatively obvious, and this may be an advantage in some aspects, such as "very close feelings." Some people's voices are more resistant to hearing with dynamic microphones. Perhaps the dynamic performance of the dynamic microphone has unique characteristics. (

　　The way the sound decays in the room is an important factor that affects the sound recording. Reverb on the role of sound is two-sided, can be better can be worse, reverberation time is one of the important conditions. Reverberation time refers to the time from when the sound source stops sound until the sound disappears completely. In a more technical language description is: the sound attenuation 60dB time required. Reverb time must be very short for voice and vocal recordings ("silent" room). Control room reverberation time is relatively short. The reverberation time between the sound and music usually depends on the type of music. The impulse response of a room (sound taken from an exploding balloon) shows all the independent reflections. 　　In the PA system, feedback over-performance is howling, which is the performance of  microphone  gain gain limit, the result of the peak superimposed.

　　Everyone's voice is unique, which creates the artistic and fun sound. Each voice has its own unique sound wave characteristics, making their own voice and others are different. 　　From men to women, ranging from rough to smooth, from darkness to lightness, the different indicators of looking at the voice are almost endless and none of them are the same. So this also means that no single microphone can completely capture these differences. 　　Microphone own frequency attribute 　　It should be noted that each microphone has its own unique frequency attributes, aware of this is very important. This frequency attribute mainly refers to the frequency response, but fundamentally speaking, each microphone will still apply its own frequency attribute to the sound of its reception, no matter how straightforward the frequency curve described on the microphone's instruction sheet is. 　　Microphone for the broadcaster is a very important item, in the selection often have to co
