The Difference Between Omnidirectional Microphone And General Microphone

The difference between omnidirectional microphone and general microphone

Generally speaking,  most people don't know anything about microphones,  except who need high quality sound,  most of them know the microphone is only two kinds, wired and wireless. This understanding is one-sided, both of which belong to directional microphones.

First of all, understand that sound divergence is all-encompassing. One person speaks and diverges in the air. As for how far it can be transmitted, it depends on many factors.

Directional microphone, the general pickup radius is very small, basically no more than three meters, single use, on the lips, the sound quality is very good, then far away the sound it does not pick up. For unidirectional microphones, the sensitivity is limited to a certain range. Sensitivity is too high and can cause sharp whistles, etc., involving many other devices.

In order to cope with this situation, a new form of Mike omnidirectional microphone was born, which is omnidirectional microphone. The general pickup radius is very large, three meters five meters ten meters are, compared with one meter, this level is very big, it is not just pick one's voice, but multiple people, up to a dozen people .

The sensitivity of the omnidirectional microphone is very high, and it can realize the function of "enabling everyone in the scene to be picked up”.The omnidirectional microphone also has an anti-echo (anti-whistle) function. The quality of an omnidirectional microphone is a very important factor in its anti-echo effect.

Summary The omnidirectional microphone is an omnidirectional, highly sensitive sound collection device with a strong anti-echo function. In the teleconferencing system, the status of voice is undoubtedly more important than video.
