How to apply large-diaphragm and small-diaphragm condenser microphones?

Author:admin   AddTime:2021-03-19

Why is there a difference in the timbre of a large-diaphragm condenser microphone and a small-diaphragm condenser microphone? In which scenarios are they used? In the early stage of the development of microphone technology, most microphones rely on large-diaphragm microphones to capture more sound energy, thereby generating higher signal voltages and overcoming the noise in tube equipment, all the way to low-noise transistors and When special microphone tubes are available, small-diaphragm microphones are slowly becoming popular because of their good signal-to-noise ratio.
So, how big is the large diaphragm and how small is the small diaphragm? In related materials, we often see this explanation. One inch in diameter is a large diaphragm and half an inch is a small diaphragm. Of course, this is just a convention. For these two types of microphones, their appearance is generally quite different. Small-diaphragm condenser microphones are often thin and long like a pencil, while large-diaphragm microphones are relatively larger in appearance.

In addition, due to their different characteristics, the timbre is also different. Small diaphragm microphones have a good performance for high-frequency signals, while the sound of large diaphragm microphones is warm and mellow. In fact, this is due to the different frequencies of these two microphones. Polarity pattern. The small-diaphragm condenser microphone can basically maintain the same cardioid direction at all frequencies, while the pointing range of the large-diaphragm condenser microphone will narrow as the frequency becomes higher. When it is at low frequencies, it almost shows Omnidirectional mode.

This is why the timbre of large-diaphragm microphones is different from that of small-diaphragm microphones, but it is also this difference that allows them to be used in different scenarios.
—❶—Large diaphragm microphone
The large-diaphragm condenser microphone can create a pleasant sound for the human ear. Therefore, when you use it to sing, the sound will be more beautiful and pleasant. So often it is not the microphone that has the function of sound repair, but the large-diaphragm brings a kind of The benign distortion makes the sound sound more ideal and romantic.
In addition, the large-diaphragm microphone can also be used for recording, not only for recording vocals, but also for solo instruments. Just like this microphone, it has a built-in 25mm large diaphragm with a wide frequency response and a wide and bright pickup effect. , Coupled with its own stable structure, and the use of advanced audio technology, can even bring the sound quality of the recording studio level.

—❷—Small diaphragm microphone
If you want detailed sound image and pick up rich audio details, then no microphone is more suitable than a small-diaphragm condenser microphone. Its tone is neutral and delicate, which can help you capture any content and make the sound more beautiful. The fidelity is higher. In addition, it is also a powerful tool for picking up the sounds of various musical instruments. Coupled with a consistent pickup pattern, it is more suitable for capturing chorus and orchestra sounds in stereo.
