I am a student, we were given an intercom to do as a project....yes my intercom works correctly but I don't know how does the components work together to produce sound can any 1 HELP PLZ

 

post schematic....

 

i attached the schematic picture

 

It looks just like a simple amplifier that amplifies the microphone and output to the earphone. It could be used as a hearing aid or a spy ear........but as an intercom? You need to have a speaker on the distant end.....

Are you sure you are posting the correct circuit?
