What is the difference between an omnidirectional microphone, an omnidirectional microphone and a un

You can check out this report.

Difference 1: The meaning is different.

Omnidirectional microphone: generally the pickup radius is very large, one meter, two meters, three meters and five meters, compared with more than ten centimeters, this level is very different, it is not just to pick up a person's voice, but multiple people, five or six, seven or eight or even a dozen.

The sensitivity of omnidirectional microphones is very high, and the omnidirectional microphone pickup radius is too large, and it will also pick up more ambient noise, so the sound quality is not as good as that of unidirectional microphones, unless the noise reduction is done well. There is definitely a difference between collective use and individual service. But the omnidirectional microphone has an advantage, the wiring is simple, and there is no need to arrange them one by one.

Unidirectional microphone: The unidirectional microphone generally supports local amplification, and the omnidirectional microphone generally does not support local amplification, which should be noted, because of such a high sensitivity, the local amplification howling caused by it is very terrifying, and it is difficult to deal with it with the current technology.

Difference 2: The scope of application is different. The speakerphone is suitable for some small meetings, ad hoc meetings, some remote discussions, remote operations. The unidirectional microphone is ideal for large meetings.

Difference 3: Different directions. One is omnidirectional and the other is unidirectional.

First of all, it is important to understand that sound divergence is omnidirectional, and when a person speaks, it diverges in the air to all directions, and how far it can travel depends on many factors.

1. Directional microphone, generally the pickup radius is very small, 30 cm is a large one, single use, put it on the side of the mouth, the sound quality is very good, because it does not pick up the sound no matter how far away.

The shape is generally gooseneck, a rod, a curved rod, reaching out to your mouth, directive, and only listening to your voice.

Unidirectional microphones, sensitivity is limited to a certain range. If the sensitivity is too high, it will cause a sharp whine, etc., and many other equipment will be involved.

As for why not make the pickup radius bigger, there's a reason for that. More on that later.

2. Omnidirectional microphones, generally have a large pickup radius, one meter, two meters, three meters, and five meters, compared with more than ten centimeters, this level is very different, it is not just to pick up a person's voice, but multiple people, five or six, seven or eight or even a dozen.

The sensitivity of the omnidirectional microphone is very high, the omnidirectional microphone pickup radius is too large, and it will also pick up more ambient noise, so the sound quality is not as good as the unidirectional microphone, unless you do a good job of noise reduction. There is definitely a difference between collective use and individual service.

But the omnidirectional microphone has an advantage, the wiring is simple, and there is no need to arrange them one by one. It is suitable for some small meetings, impromptu meetings, some remote discussions, remote operations.

3. The unidirectional microphone generally supports local amplification, and the omnidirectional microphone generally does not support local amplification, which should be noted, because of such a high sensitivity, the local amplification howling caused by it is very terrifying, and it is difficult to deal with the current technology.

However, the remote echo has been better handled, and foreign Polytong, Yamaha, and domestic front-end Puyue electroacoustics have better echo cancellation omnidirectional microphone products.

Do you still understand what directivity is, directivity is divided into unidirectional, bidirectional, omnidirectional, unidirectional included, cardioid direction, supercardioid direction, bidirectional including figure 8 direction, double stereo direction, omnidirectional, only this is 360° no dead angle pointing.

Depending on the purpose, the directivity of the microphone is also different, and it is divided into "cardioid", "supercardioid", and "omnidirectional". "Cardioid" "Super cardioid" receives sound in the direction of the microphone mainly in front of the microphone, which is used for solo singing and language pickup; The "omnidirectional" microphone can receive sound in 360° and is mainly used in studios, live interviews, etc.

Summary. Hello! Omnidirectional Microphone:

Magnetic, ceramic, and electret microphones are all omnidirectional microphones, i.e., they accept sound in all directions in equal amounts. At present, electret microphones are widely used in the field of acoustics, and they are made of an insulating, permanently polarized material. When the sound enters the microphone, the dense change of the sound wave causes the negatively charged thin metal sheet to vibrate, randomly converting the sound energy into mechanical energy, and the diaphragm vibrates to generate pressure on the electret body, which is transmitted to the back plate of the electret body.

Both the electret backplate and the bottom of the diaphragm are connected to the FET preamplifier and have a terminal leading to the outside. When the distance and space between the diaphragm and the back plate of the electret change, a voltage is generated, which converts the mechanical energy into electrical energy through a field-effect transistor fixed to the microphone, which is then transmitted to the amplifier through the terminal. Electret microphones are wide-frequency, sensitive, and durable, and the diaphragm is the only part of it that moves.

Hello, I am helping you to inquire about the relevant information and will reply to you immediately.

Hello! Omnidirectional microphones: Magnetic, ceramic, and electret microphones are all omnidirectional microphones, i.e., they accept sound in all directions in equal amounts.

At present, electret microphones are widely used in the field of acoustics, and they are made of an insulating, permanently polarized material. When the sound enters the microphone, the sparse change of the sound wave causes the negatively charged thin metal sheet to vibrate, and randomly converts the sound energy into mechanical state energy, and the diaphragm vibration generates pressure on the electret body, which is transmitted to the back plate of the electret. Both the electret backplate and the bottom of the diaphragm are connected to the FET preamplifier and have a terminal leading to the outside.

When the distance and space between the diaphragm and the back plate of the electret change, a voltage is generated, which is converted into shielded electrical energy through a field-effect transistor fixed to the microphone, which is then transmitted to the amplifier through the terminal. Electret microphones are wide-frequency, sensitive, and durable, and the diaphragm is the only part of it that moves.

The speakerphone is a portable conference product, with computer network conference function, wireless mobile conference function and recording function. So what is the difference between an omnidirectional microphone and a unidirectional microphone?

1. Pickup range: The general pickup radius of one-way microphones is very small, 30 cm is large, and the sound quality is very good when used by a single person, because it does not pick up the sound of the rubber in the distance. Omnidirectional microphones, generally have a large pickup radius, one meter, two meters, three meters, and five meters, not just to pick up one person's voice, but multiple people, five or six, seven or eight or even a dozen.

2. Sensitivity: The sensitivity of one-way microphones is limited to a certain range, and too high sensitivity will cause sharp whistling and many other equipment involved, which is suitable for single service and stuffiness. The sensitivity of the omnidirectional microphone is very high, the omnidirectional microphone pickup radius is too large, and it will also pick up more environmental noise, so the sound quality is not as good as the unidirectional microphone, suitable for group use.

3. Whether to support local amplification: one-way microphone generally supports local amplification; The omnidirectional microphone generally does not support local sound amplification.

It can be seen that the difference between an omnidirectional microphone and a unidirectional microphone is in the pickup range, sensitivity, and whether it supports local sound amplification.
