Q4 :How to choose the microphone?
Directional:  According to the sound receiving range, the microphone is divided into omnidirectional, unidirectional, and noise canceling. The noise canceling microphone is designed to decay the low frequency far. Most customers use omnidirectional microphone; the unidirectional is only used in some special occasions, therefore we should pay more attention to mechanical and circuit design.

Sensitivity: The sensitivity of the microphone affects the recorded volume. However, high sensitivity doesn’t mean a good microphone. The good circuit design is also necessary for getting better results. We suggest selecting a middle common sensitivity at beginning. Too high or too low might affect the lead time and the price.

Test condition: The test voltage and the impedance affect the sensitivity of the microphone. Generally speaking, the higher the voltage and the impedance is the better sensitivity we get. Therefore, the test condition is for reference and IQC only, which is usually different to the reality.

Dimension: Diameter is from 2mm to 14mm, height is from 1.1mm to 6.7mm. 4*1.5, 6*2.2, 6*2.7, 6*5.0, 9.7mm are common spec.
