What Is a Condenser Microphone?

The condenser microphone uses the change in the size of the capacitor to convert the sound signal into an electrical signal. This type of microphone is the most common. Because it is cheap, small in size, and the effect is not bad. Sometimes called Mito.

Electret

Condenser microphones have two metal plates, one of which is coated with an electret film (mostly perfluoroethylene propylene) and grounded, and the other plate is connected to

Can directly convert sound into electrical signals

The condenser microphone uses the principle of capacitor charging and discharging between conductors, and uses ultra-thin metal or gold-plated plastic film as the vibration film to induce sound pressure. The static voltage between conductors is directly converted into electrical signals, which are obtained through the coupling of electronic circuits. Designed for output impedance and sensitivity.

Can show the characteristics of original sound reproduction

Acoustic experts pursue the "acoustic reproduction" as the highest level of audio! From the analysis of the basic design principle of the microphone, it is not difficult to find that the condenser microphone not only relies on precise mechanism manufacturing technology, but also combines complex electronic circuits to directly convert sound into electrical signals. It has inherently superior characteristics in nature, so it has become a pursuit The best choice for "reproducers".

Has extremely wide frequency response

The diaphragm is the main component for the microphone to sense sound and convert it into electrical signals. The material of the diaphragm and the design of the mechanism determine various characteristics of the sound quality of the microphone. Because the diaphragm of the condenser microphone can be made of extremely thin materials, and the induced sound pressure is directly converted into audio signals, the frequency response of the bass can be extended to ultra-low frequencies below 10Hz, and the treble can easily reach tens of KHz. Ultrasonic waves show a very wide frequency response!

With high sensitivity

Because there is no voice coil load on the diaphragm, it can use extremely thin design, so not only the frequency response is excellent, but also it has excellent sensitivity, it can sense very weak sound waves, and output the most clear, delicate and accurate original sound!

Fast transient response

In addition to the characteristics of the frequency response and sensitivity of the microphone, the ability of the diaphragm to respond to sound waves, the so-called "instantaneous response" characteristic, is one of the most important factors affecting the sound quality of the microphone. The speed of the microphone's instantaneous response depends on the weight of the entire diaphragm. The lighter the diaphragm, the faster the response speed. The extremely thin and thin vibrating diaphragm of the capacitive sound head has extremely fast transient response characteristics, and it can show clear, bright and powerful sound and accurate audio and video. In particular, the middle and low frequencies are completely free of color tone and "box sound", and the high and fine sounds are delicate and crisp, which is the most prominent characteristic of the capacitive type. It can be clearly seen from the following drawings that the instantaneous response characteristic of the capacitive voice head is much better than that of the dynamic coil type.

Features ultra-low touch noise

The touch noise caused by the contact with the palm when using the handheld microphone makes the original sound mixed with extra noise, which has a great impact on the sound quality, especially for the preamplifier circuit.

The structure is complicated, the cost is expensive, the sound film is fragile, and it is afraid of moisture.
