In our daily life, the frequency of microphones (microphones) may not be high, but for some people, microphones are especially important. For example, network anchors and singers are inseparable from it; recordings, venues and other environments are also indispensable. Maybe you have heard of the condenser and the moving coil type before, and you know that there are microphones such as Sennheiser MK4 and Shure SM58. So what is the difference between them? If you choose a microphone that suits you, how do you choose?
How does it work differently:
The so-called dynamic microphone (hereinafter referred to as dynamic microphone) and condenser microphone (hereinafter referred to as condenser microphone) refer to the type of microphone radio head. The common microphones on the market are mainly divided into these two types. So what is the difference between the two in working principle? The dynamic wheat uses the principle of electromagnetic induction. The wire coil is mounted on the diaphragm, and then placed between the magnetic fields of the magnet. The sound current changes continuously in the magnetic field to generate an induced current, thereby converting the sound signal into a signal. . Its switching principle is very similar to that of a speaker. Capacitor Mai uses the charging and discharging principle of the capacitor. The vibration of the sound drives a plate of the capacitor (ultra-thin metal film). The vibration of this plate changes the distance between the two plates, which in turn changes the capacitance. When the capacitance becomes larger, the power supply charges the capacitor; when the capacitance becomes smaller, the capacitor discharges, thereby generating a current in the circuit and converting the sound signal into an electrical signal.
First, what are the differences between the two in terms of structure?
What is the difference in structure:
Structurally speaking, the dynamic ring wheat is mainly composed of a coil, a diaphragm and a casing, and has a firm structure, stable performance, relatively durable, and easy to control cost. So the microphones we usually use in KTV are mostly dynamic. Of course, there is another reason. The use of dynamic wheat is also very simple. It can be used even when connected to the equipment, without DC working voltage.
But for Capacitor, everything becomes less simple. Structurally, the internal capacitor of the sound head has a complicated structure, the electrode plate (ultra-thin metal film) is relatively fragile, the cost is high, and it is afraid of moisture, fear of falling, and high maintenance cost. In addition, there is an amplifier in the condenser, which needs power supply to work. But because of the size of the microphone, this power supply is usually designed as an external type, its name is called "Phantom Power" (Phantom Power).
The so-called "phantom power" power supply means that the audio signal current can be transmitted in the same audio signal line, and the DC power supply voltage can be transmitted. In general, most condenser microphones require 48V phantom power, so many professional mixers also have built-in 48V phantom power. However, some professionals have also said that the use of 48V phantom power will produce current sound, which will affect the final recording effect, but I think this is limited to some professionals who are nitpicking the sound quality? I don't know what everyone thinks about this.
Electret condenser wheat:
In addition, there is a capacitor wheat battery powered, known as electret condenser wheat, which has the characteristics of small size, simple structure, good electroacoustic performance and low cost, and is suitable for mass production. Widely used in conferences, voice communication equipment, voice recorders, video cameras, mobile phones and other products. However, the sound quality of the electret condenser microphone is relatively poor, so it is often used in situations where the sound quality is not high.
Second, what are the differences between the two in terms of sound quality?
What is the difference in sound quality:
As we said before, dynamic wheat is widely used in entertainment such as KTV or performances. In addition to low cost and simple use, is there any other reason? This requires starting from the other characteristics of the dynamic circle. Due to the structure, the sensitivity of the dynamic ring wheat is relatively low, and the frequency response is not wide enough (the frequency response range is 50 Hz to 15 kHz, and the human ear can hear the frequency response range is 20 Hz to 20 kHz). Therefore, its high-range extension is not good enough, and the weak sound induction will be slower (slow transient response). Simply put, the sound is not delicate enough and the details are not rich enough.
But everything has two sides, the performance of the dynamic wheat is lacking, but its sound is softer and more sturdy, and the singer's song is more full and round, or better. Recall that when you sing at KTV, even if you turn off EQ, your voice seems to have been added some effects. In addition, dynamic wheat has a good inhibitory effect on ambient noise, which is why it is more suitable for more noisy occasions.
From the point of view of the parameters of the condenser wheat, it is obviously much better than the dynamic circle. Its high sensitivity, wide frequency response (20Hz ~ 20kHz), fast transient response, high sound reproduction, etc., can handle high boost with ease. The sound of the condenser microphone is clear and bright, and those professional singers usually use condenser mic to show their natural and beautiful voice. Therefore, condenser mic is widely used in professional vocal singing, studio recording, film recording, instrument pickup and other occasions. Therefore, condenser microphone can be said to be the best choice for recording.
However, the condenser mic is also not perfect. Because of its high sensitivity, it is easy to collect the noise of the surrounding environment. Therefore, in high-noise environments such as large-scale outdoor performances and film and television, the condenser mic is usually not used. Not only is there a lot of noise, it can also cause damage to the microphone. At this time, the dynamic circle Mai came in handy.
Section: Dynamic wheat and capacitor wheat may not be good or bad, but their respective uses are different. Dynamic wheat is preferred in noisy environments and when there is no high demand for sound quality. In professional recordings, or where high-quality, clear sound is required, Capacitor is your first choice.
Third, the focus is on this, how to choose the wheat that suits you?
Having said that, some people may ask: "There are so many microphones on the market, how do you choose one that suits you?" I also want to talk to you about this issue. When choosing a microphone, it is not only expensive to choose, it will only make you spend money, and you may not be able to get satisfactory sound quality. What you need is a microphone that best matches your voice.
Be aware that everyone's voice is unique, and each voice has its own sonic characteristics. From the high range to the low range, from smooth to rough, these waveform differences make your voice separate from others. Similarly, each microphone has its own frequency response, which is the best microphone for you if its frequency response matches your voice.
It looks pretty, but there is nothing deep in it. For example, if you have a high voice like "Small Shenyang", then condenser mic may not be suitable for you (because the excessive sensitivity will bring more harsh teeth). What you need is a dynamic wheat that can cut high frequency and warm the sound.
On the contrary, if your voice is thick and low, the dynamic circle is obviously not suitable. What you need is a condenser mic that boosts high-frequency brightness and detail, and this type of microphone can match your voice better. So, choose the right microphone to complement your voice and make your songs more pleasant.
Written at the end:
Understand the difference between dynamic wheat and condenser wheat, I believe that you will have some help in choosing a microphone in the future, so that you can find the vocal wheat that suits your voice faster. Don't underestimate this process. It allows you to be more confident in your own voice when you are recording songs or recordings, and more people will vote for appreciation. Therefore, do not blindly pursue expensive, match your own voice is the best. (collected from the network)
