Advantages and disadvantages of silicon microphones:
1. Silicon microphone MEMS MIC has high temperature resistance and reflow soldering resistance, and can be directly SMT surface mounted.
2. The sensitivity of the silicon microphone is stable and there is no change. The silicon microphone does not require resident charges or electret materials, and the product has good stability.
3. The curve of the silicon microphone is straight, but the frequency response curve cannot be adjusted according to the changes in the usage scenario, and directional design cannot be done.
Advantages and disadvantages of ECM microphones:
1. The ECM microphone has high sensitivity, a very wide frequency band, and low nonlinear harmonic distortion. The frequency response curve can be adjusted by designing circuits and changing materials according to different usage scenarios,
If you need to suppress environmental noise, you can choose a single or dual directional microphone, which has multiple options and can achieve good results.
3. The production process requires manual operation and cannot be surface mounted
