Electret Mic Schematic
Electret Mic Schematic
Please note that the "capacitor" component shown in the electret capsule schematic above is represented by the pick-up plate + the electret material, which together create a capacitor. The electret microphone operates in the range of 1.5-10V (typically 2V) and the current between the JFET's Source-Drain (ground-output) is usually max. 0.5mA.
An electret microphone is a type of electrostatic capacitor-based microphone, which eliminates the need for a polarizing power supply by using a permanently charged material.. An electret is a stable dielectric material with a permanently embedded static electric dipole moment (which, due to the high resistance and chemical stability of the material, will not decay for hundreds of years).
MIC). An extremely high resistance, R G, may be included to bias the gate of the JFET. I MIC R G V G Sound Wave Microphone Capacitor with Electret JFET Figure 2: A simplified circuit schematic of an electret microphone An example construction of an electret microphone is shown in Figure 3. One electrode of the capacitor is
