What is this? (speaker circuit) Answered
I found a pair of broken speakers in a junkyard a while ago and wanted to take the good-looking connectors. When I removed them from the chassi I saw that there was a circuit board on the other side and now I wonder what it does. At first I thought it was an amplifier, but there is no connection for power or batteries. I made some schematics of the circuit, I hope that will help. Gogo gadget, internet community intelligence!
