I am trying to make an electret mic preamp with lm358. here are the pspice simulation results. I measured the voltage of the pins and the values ​​were simulated exactly like the sample. I tried with 5 to 11 volts. Regardless of the slight noise, the circuit has good sensitivity to sound. But the speaker sound is weak. Low current consumption circuit (up to 10mA) Can you guide me? Thankful
