How to choose a good entertainment microphone?

Author:admin   AddTime:2021-05-28

In a typical recording or karaoke environment, the sound quality is usually affected by two factors: pickup and digital-to-analog conversion. The pickup quality of the former is determined by the microphone, and the digital-to-analog conversion of the latter is determined by the sound card. Therefore, the quality of the final sound signal depends on the performance of the above two types of hardware. Therefore, the hardware performance indicators should be used as a basic reference when selecting equipment. This article will introduce the choice of the most front-end microphone for acoustic-electric conversion. 



A microphone, or an entertainment microphone, is a component that converts sound signals into electrical signals. From the perspective of bionics, the design concept of the microphone is almost the same as the human auditory system. The difference is that the microphone converts sound pressure into electric current through an electromagnetic field to obtain an electrical signal. This is what we usually call the "sound pickup" process, and we usually understand it as an acoustic-electric conversion process. The collected sound can be divided into stereo and mono sound. The so-called stereo is to use two or more (auxiliary) microphones to simulate the sound of two human ears to obtain the signals of the left and right channels. Mono sound is like the sound of the human ear, and the signal has only one direction.

In the production of professional student music, microphones (entertainment microphones) are divided into two categories according to the differences in the teaching content recorded by themselves, namely "instrument microphones" and "voice microphones". According to its structural development characteristics and working life style, it has been refined into three categories: dynamic microphone, aluminum tape microphone, and condenser microphone. Their common learning characteristics are: both have a diaphragm and electromagnetic effects. The basic principle of its work is: the diaphragm changes the electromagnetic field under the impetus of the sound pressure change, and produces a huge change of voltage. After the output, it can produce a sound through the continuous amplifying circuit. Because K songs are mainly monophonic vocal recording or live singing, there is no restriction on the recording format, so there is a relatively traditional single in this form, and the technology is relatively simple and easy to understand. So the next step is that we will focus on the structural design features and work management methods of the "vocal microphone" to further study and analyze the problem of how to choose entertainment microphones from the perspective of technical main parameters. After we understand this knowledge, it is more convenient for us to choose entertainment microphones, and we can be more familiar with the relevant knowledge of the product.
