How do I connect a little speaker to an audio jack? Answered

I got a speaker from a toy( that used batteries) and I want to connect it to some old headphones cable. Do I need to do a circuit with batteries? The audio jack got 4 thin wires (1 blue 1 green 1 red and 1 yellow)? In which order do i need to connect it?

It depends where your audio is coming from. IF you can plug in ear phones and hear something then you will be Ok to plug it direct.

You have a 4 ring plug so this is intended for a mic to be used. the connections are as in the attached diagram click for full size.

You will need a resistance or multi meter to check which wire connects to which ring. Or a battery LED and resistor.
