hi,,, im doing my final year project about wireless transmission of voice signals to its speakers,, where the speaker is a reciever powered by a low dc voltage source (9-16volts).. a microphone serves as its input, connected to a transmitter that transmits data to its speakers wirelessly... fm modulation and operates at a certain freq...

could anyone suggest a transmitter circuit for its microphone and a reciver circuit for its speakers.... tnx in advance..:)

i might also consder a ringing button,. this button rings a bell sound to its speaker... a warning message perhaps?..:) or needs not to be pressed.. runs thru a specified time's of the day?..

tnx very much.... God bless...
