My bluetooth headset speaker uses 3 wires, what gives?
I'm trying to mod my bluetooth headset to give better sound quality and volume. I disassembled the whole thing, but I noticed something kinda weird. The speaker on the BT headset has 3 wires coming off of it, instead of the usual 2 that most speakers use. The 3 wires are:
2 that are of a similar color and are connected to where the magnet of the speaker would sit. They're not connected to the same spot. One is connected to the 3 o clock position of the magnet of the speaker, the other is connected to the 9 o clock position.
1 that appears to be connected to the metal speaker housing (I'm assuming is the ground?)
Anyone know why this Samsung unit uses 3 wires to power the speaker?

The third wire could IN FACT be there as a sort of "feed" back wire so your headset can automatically adjust the quality/sound coming out. Althought that's unlikely what it's for, I have seen speakers (most particularly tweeters/midrange) that have 3 jacks on them not just 2.
