Hi All,
I am trying to make a circuit which will have a speaker(or buzzer) and earphone. The functioning of the circuit will be similar to what we see in present day devices. As soon as the earphone is plugged in the jack, the sound output should come only in the earphone and not in the speaker. The sound out is only alarm beeps (not any other audio or song etc).
I need some guidance in where to look for reference design and suggested readings. I am searching the internet, but it will be nice to get guidance from this forum
