Omnidirectional Microphone Module I2S Interface Inmp441 Mems High Precision B6W2 The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port.The complete INMP441 solution consists of a MEMS sensor, signal conditioning, analog to digital converter, anti-aliasing filter, power management and industry standard 24-bit I2S interface. The I2S interface allows the INMP441 to be directly connected to digital processors such as DSPs and microcontrollers without the need for an audio codec for use in the system.
What is the difference between an omnidirectional microphone and a unidirectional microphone:1.directional microphone, the general pickup radius is very small, 30 cm is a big one, single use, put it on the mouth, the sound quality is very good, because it is not picked up again.The shape is generally goose neck wheat, a rod, a curved rod, to your mouth, directivity, just listen to your voice.
With a single-point microphone, the sensitivity is limited to a certain range. Sensitivity is too high, causing sharp whistling, etc., involving many other devices,As for why not make a big pickup radius, there is a reason. Later,2.omnidirectional microphone, the general pickup radius is very large, one meter two meters three meters five meters have, compared with ten centimeters
this level is very different, it is not just picking a person’s voice, but Multiple people, five six, seven eight or even ten.But omnidirectional wheat has a benefit, the wiring is simple, not one by one. Suitable for small meetings, ad hoc meetings, some remote discussions, remote operations.
Omnidirectional microphones are highly sensitive,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 single-point microphone, unless you do a good noise reduction. There is definitely a difference between collective use and single-pe
