Hi there, sorry if this is a silly question but i was stumped on it for quite some time hoping you guys can help me out over here.
As you guys know, there are 3 wires in a headphone, Left , Right and Ground.
As far as i know (might be wrong,) AC is used to produce sound from the vibration of the voice coil in the headphone caused by the repulsion/attraction from the magnet in the headphone.
My question is this.. since Left and Rright have different currents to produce different sounds, and that L and R share the same ground wire (saw that when i cut up my earphones), is it true that coupling of the currents occurs?
However, i don't think that's the case since if coupling occurs then both L and R would play the same sound. So how exactly does AC work such that both L and R play different sounds and yet share the same ground cable?
As of now, i'm guessing that there's some kind of short circuit going on which prevents the audio from L and R to mix. However, since AC is non directional (correct me if i'm wrong), does coupling still occur at the point where the ground wire combines?
i drew a pic for easier visualization..
L is the red wire, R is the green wire and yellow is the ground.
Would really appreciate it if you guys could help me out. (i might have quite a few misconceptions here so if you guys spot any, feel free to point them out.)
Thanks again!
