hi everybody

i am making my FM transmitter to transmit voice/audio throgh mic or any audio device like computer output, MP3 player etc. but the problem i got is little but tricky. the problem is that the audio input socket i m going to use has two terminals for connecting to any circuit but, the FM transmitter circuit i m using shows only one connection to audio input.

so please help me, that how to connect an audio input socket with its two terminal with a circuit with only one connection for audio input.

you can see my circuit diagram below.....

 

Hello,

The minus connection of the battery is also audio ground

Then you have the two connections for the audio.
