Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Schematic
We are going to hit wire this by making a cable that directly links the media source with the speaker.
According to the diagram below, if you have a stereo plug, you want to combine the signal of the left and right channel together, connect this to one alligator clamp. then take the ground connection, and attach it to another alligator clamp.
(Clamp connection to speaker in next step)
Step 2: Application:
You want to take the two alligator clamps and attach them to the closest leads coming out of the speaker possible, but one the outside of the speaker, do not connect it to the small wires that run from the small board in the picture below to the paper of the speaker! The ones that go between the metal supports and the speaker paper are off limits for this project!!
Ensure that they are well insulated clamps from surrounding metal, such as the near by magnet, so the magnet does not draw them to touch each other, or touch something conductive, and short! Do not work with live wires, have it unplugged fro your media source.
Step 3: Play Your Media
Older speakers will not be abe to push much volume, it will cut out if you try and give it too much juice.
you can probably work safely at 50%-65, maybe 75% volume on a standard music player at a normal volume track.
