Pocket Speakers

Step 3 Assemble and Solder

This step is fairly easy, simply thread all three wires through the holes in the plastic, or tape/glue them to the tin if you didn't have a plastic cover. And solder all 2 - 4 points. Generic stereo jacks from headphones have two wires, and two more in each one. (I'm not much of an electronic savvy guy so I'll let other people correct me here) The non insulated inner wire is ground and the insulated one is the power supplying one. I've found that it doesn't matter which one goes where on simple speakers (by testing normal and reverse connections) so solder away.

*Side note, if you haven't already, any sort of computer speaker usually comes with a little plastic end that helps connect the wires to the pins on the motherboard. You can take this off by using an Exacto knife or pin to press down the locks on one side of the plastic end and pull individual wires out. Unfortunately these things are rather small, especially on two wire pin connections and coming from a laptop. My camera was unable to take a photo of these little things (even with macro).

The red and green should be the positive leads for each speaker/ear-bud, i'm not quite sure what the convention is for left and right though, you can play around with it, but in my case it didn't matter cause i could switch them anyways. The copper wires are ground and connect to the negative lead. Unless your speaker specifies which is negative and/or positive, it shouldn't matter how you hook it up, just maker sure you have the left and right (green and red) going to different speakers. If your hooking speakers directly into a 3.5 mm jack, they have 3 solder points on the inside, 2 coming out of the middle and one on the outside. The two on the inside are left and right, the outside is ground. so you would connect both copper/ground/negative wires to that point.
