Hello All,
I wan to design a small circuit which is connected to the PC sound card and the Speakers with a headphone jack so that when I connect the headphones the speakers are disconnected automaticly without having to use a manual switch. Is there a circuit design for such thing.
Thank you very much.
well your asking for what many radios and other things do that have built in speakers that are automatically excluded when headphones go in. either try and buy one or get one out an old appliance.
well i tried that solution already but the circuit takes in a dc voltage from a transformer which of course is not what i need, i need a one that will only use the current from the PC connection, any way thank you for your help.
