The modern design omni-directionalconference microphone to the conference - Tenveo

When it comes to microphones, most human brain images appear like "lollipop" microphones, but when it comes to omni-directional microphones, many people have no idea. In fact, the omni-directional microphone is a portable conference call product that enables high-quality web conferencing over the Internet and high-quality wireless mobile conferencing. However, different diaphragm microphones are different.
First, the noise:
Large-diaphragm microphones produce less self-noise than small-diaphragm microphones due to the Brownian motion that causes the microphones to create self-noise. Smaller diaphragm work similar to a hard plane, the collision of air molecules will release more energy, so the noise is large.
Second, the sensitivity:
Omni-directional microphones with large diaphragms are not only more mobile, but sometimes even have lower sound pressure levels and therefore provide more output information.
Third, the sound pressure level processing:
Hard small diaphragm can deal with higher sound pressure level than large diaphragm.
Fourth, the frequency range:
The upper frequency limit is determined by several factors, all of which are related to the dimensions of the diaphragm:
Large-size diaphragm is more prone to rupture, resulting in it can no longer play its role as a piston.
2. The greater the weight of the diaphragm, the less the displacement of the diaphragm under higher frequency conditions.
3. Diffractions around the edge of a sonicator cartridge limit the ability of the microphone to handle higher frequencies.
Therefore, it can be concluded that the large diaphragm microphones and small diaphragm microphones compared to its frequency range has some limitations.
Introduced above the omni-directional microphones and small diaphragm-type film part of the difference. In fact, the size of the diaphragm, whether large or small, they have their own advantages and disadvantages. We can choose according to their own needs.
