Speaker Sharing

Does anyone have a simple circuit that will allow me to mix my iPod audio out with my computer’s audio to play through the same speakers? I want to avoid un-plugging/re-plugging just to hear some music.

I use a simple DPDT toggle switch for something like this. I switch my computer output between speaker and headphones without wearing out the headphone jack.

In your case, the audio to the speaker would be switched between the iPod or the computer. The speakers must be amplified, and the computer’s output volume adjusted down to be close to the level coming out of the iPod headphone jack. You can mount the jack and switch on the speaker.
