This is wonderful circuit for you guys.because we can use a normal speaker instead of a mic.When the voice waves touch the speaker.Magnetic field is changed in it.As a result of that it releases small electric signal to the transistor and transistor increase it.you can make this one as a intercom too.Then you have to use two circuits for that.try this...

pls send full informaion mi & speaker.
you can use a 8ohm speaker as a mic and the speaker.
can u tell me clearly the function of each capacitor and resistor, why we have to use up to MEGA ohm, and the other just 8 ohm?
