I'm trying to transfer sound from an electret microphone to my speaker.
I'm copying a simple circuit from the Internet with 5V source from USB and a 1Kohm resistor. However, because I don't have a capacitor here, I removed it from the circuit.
The output is connected directly to the speaker. After finishing it, I tested my project by saying some words into the electret microphone. It can reproduce my voice when I bring my mouth very close to the microphone and talk 'uuuuuuuuu' 'aaaaaaaaaaa'. It can record my breath when I blow to it. But it cannot reproduce any other sound around me or 'real human voice' as a working microphone. What am I doing wrong in my project?
