How Electret Microphones Work. An electret microphone mainly consists of a diaphragm, a couple of electrodes and an in-built JFET. The diaphragm is made of thin Teflon material and is also termed as “electret” and hence the name electret MIC. This electret has a fixed charge (C ) and is embedded between the two electrodes.

What is the best preamplifier circuit for electret

\$\begingroup\$ Unlikely that a preamp made to work with dynamic microphones and electret microphones will sound good with either. For starters, you need much more amplification for a dynamic microphone than for an electret. If the preamp has enough gain for the dynamic, it will have too much when used with the electret. \$\endgroup\$ –
