MEMS silicon microphone simulation is widely used in industries
such as medical communication, intelligent robots, VI, and in
vehicle communication. Adopting imported wafer packaging, with
excellent high-frequency anti-interference and anti howling
functions, it is particularly suitable for car microphones,
conference microphones, hosting microphones, KTV microphones,
teacher amplifiers, and KGeBao microphones. Introduction to MEMS
silicon microphone analog parameter function:
1. Voltage: Supports 1.6-3.6V power supply,
2. Directionality: omnidirectional
3. Signal to noise ratio: 64DB
4. Harmonic distortion: 0.1%
5. Maximum sound pressure: 120DB
6. Sensitivity: -38DB ± 1
7. Foot position: The 2-foot position is one less ground point
than the regular 3-foot position. There is a slight difference
in structure
The biggest difference between ordinary analog silicon
microphone and noise reduction silicon microphone is that
1) The main requirement for noise reduction in silicon
microphones is that the low-frequency response curve of silicon
microphones should be straight from 30Hz to 1KHZ. The frequency
response curve of ordinary communication silicon microphones
below 100Hz is greatly attenuated
2) The signal-to-noise ratio parameter value of noise cancelling
silicon microphone will be higher than that of ordinary silicon
microphone
