Microphone category editing
1. From the working principle: carbon particle type, electromagnetic type, capacitance type, electret type capacitance type (the following is mainly based on electret type), piezoelectric crystal type, piezoelectric ceramic type, silicon dioxide type, etc.
2, from the size of the size, the electret can be divided into several kinds.
Φ9.7 series products Φ8 series products Φ6 series products
Φ4.5 series products Φ4 series products Φ3 series products
Different heights in each series
3, from the directionality of the microphone, can be divided into omnidirectional, one-way, two-way (also known as denoising)
4, from the polarization mode, diaphragm type, back pole type, front pole type
From the structure, it can be divided into gate spot welding type, gate pressure bonding type, pole ring connection type, etc.
5, from the external connection method
Ordinary solder joint type: L type
With PIN foot: P-type
Concentric circle: S type
