Weak current College】 【dynamic microphone and capacitor microphone acoustic performance of distinction --- Power By】 【China power house network.

Generally speaking (and of course there are exceptions), capacitor microphone in the sensitivity and extended high-frequency (sometimes is the low-frequency) respond better than dynamic microphone.

This capacitor microphone needs to be sound signal into current works. Typically, capacitor microphone diaphragm are very thin, very vulnerable to the effects and sound pressure, and thus cause of vibrating and vibrating tanks back the corresponding change between voltage. This voltage change next will undergo preamplifier times zoom, and then converted to sound signal output.

Of course, this preamplifier is built-in in microphones at the amplifier, instead we commonly referred to as the "front words" that is, a mixer or interface with the preamplifier. Because of the capacitor microphone diaphragm area is very small and therefore, its low-frequency or high-frequency response of the sound signal is very sensitive. The fact is true. The vast majority of capacitor microphone will be able to accurately capture the human ear does not hear the sound signal.

In contrast, a dynamic microphone works to simple. It is largely dictated by the conductor in a magnetic field of the movement to produce a sound signal. In fact, usually we say dynamic microphone, strictly speaking, it should be called "moving coil (moving-coil)" moving-coil microphone, because the microphone sound signal generation, mainly by hand in hand with the vibrating wire coil according to sound pressure changes in the magnetic field in constant motion. As part of the volume of which exercise a relatively large, therefore, the circle of the microphone in the response frequency range (mainly the high frequency part), sensitivity and instantaneous response capacity than capacitor microphone poorrelation.

Aluminum belt microphone (RibbonmICrophones) is a dynamic microphone. It and moving coil microphone (moving-coilmicrophone) the major difference is that it uses a very thin metal film instead of the latter the diaphragm and the coil. It is mainly through the metal itself according to sound pressure changes that occur with vibration, to lead the field in the current changes, thus resulting in the sound signal. Due to the relative size of the metal sheet and coil to small diaphragm, thus, the aluminum belt type microphones against high-frequency response capacity than moving coil microphone, however, still can't and capacitor microphone.

Dynamic microphone sensitivity less than capacitor microphone, mainly because it is no electronics inside to sound signal amplification and buffering. Thus, they will usually be better than dynamic microphones require more gain. That is why dynamic microphone sound usually can vary with different with preamplifier without corresponding changes. However, strong sources, generally does not cause any adverse consequences, however, if the audio source weak, then the problem may be more serious, you need to pay special attention. Market demand is the catalyst for product innovation.

To resolve this problem, the current market has really emerged directly built-in preamplifier dynamic microphone, such as BLUE launched Ballmoving-coil (moving coil microphone) and Royer launched R122ribbon (aluminum belt microphone), etc.

As it turns out, they did well with various preamplifier phase applies. Because each handset has its own unique strengths and weaknesses, and therefore, if you watch carefully, you will find that each handset has its own dedicated application context. For example, a moving coil microphone normally guitar amplifier, brass, drums and live voice of near-field strong sound source recording environment; and the capacitor microphone is usually under natural conditions or on the high-frequency response range demanding conditions, such as hanging top recording drums, piano, acoustic stringed instruments, voice recording, as well as the work of Interior and choral recordings, the Orchestra; aluminum belt microphone in digital recording, particularly percussion and brass in the process of recording more and more attention.

Of course, the aluminum belt microphone can also be used for a variety of acoustic guitar amplifiers, musical instruments, as well as the human voice and other audio applications. Finally, I would like to say that any rules are just reference only, and do not necessarily have to be complied with. Although few people recommended we use moving coil microphone for recording acoustic guitar or drums sound recordings for hanging on, however, if you want to try, because the rule is dead, but the person is alive. In fact, in reality, we can see a lot of similar to a scene vocal recording using capacitor microphone, the voice recording work indoor use dynamic microphone, or even use a capacitor microphone to record the drums for near-field and seems to have achieved good results. This tells us that the key to select the phone to see if it is able to achieve your intended results, and not just to comply with the established rules.
