Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Get the Materials

It's pretty simple,all you need is:-

1.A strong neodymium magnet (get it from eBay or search in your home)

2.A spring or any bouncy spring-like thing.

3.An old and used CD which has no use.

4. Some copper to twine on a paper.

5.Some wires for connecting the speaker to the input source.

6.A used plastic bottle.

7.Some aluminum foil.

Step 2: Get the Copper Twined and Ready.

Take the Copper wire and roll it on any circular object.
Leave 4 to 6 cm of wire loose on both ends.

Step 3: Stick It to the CD

Stick the paper with the Copper wire to the CD and burn the ends to remove the insulation .

Step 4: Place the Magnets and Springs.

Stick the magnet in the centre and the springs around it forming a square.

Step 5: Place the CD on It.

Stick the CD with the Copper below and make sure the Copper doesn't touch the magnet.

Step 6: Add the Diaphragm.

Cut open the water bottle and stick the aluminum foil as shown in the pic.

Stick this Diaphragm to the top part of the CD.

Step 7: Wire It Up.

Take the Copper wire ends and using some wire connect it to your input - a phone,microphone or a CD player ( preferably the CD player as it has more power.)

Step 8: Enjoy the Speaker.

Get some loud music and enjoy the blast!

    This is such a watered down dysign that nobody owns the intellectual property rights to it.

    I remember way back in the early 70s in High School Electronics class. Some cranially challenged guy would come into the shop and ask the teacher if anyone could make him a speaker. My instructor would kindly give them the 2-minute lesson as to how speakers themselves needed to be manufactured, while us guys in "The Big Bang Theory" club tried not to laugh out loud lest we pay later on. Too bad we didn't have your invention.

    All kidding aside, your invention is remarkable. I can see you and others refining the design as to wire gauge, number of turns of wire, spring tension, and maybe other parameters to refine the fidelity. My only warning, from experience, would be to put a resistor in series with the coil. Something 20 ohms or less, just enough for the electronics in the driving device to not see a dead short across the speaker terminals. At worst you could fry the output stage on some devices. But most likely you will trip an over current protection circuit (Like I once did on my $600 receiver playing the Stones too loud) and then wonder what happened.

    Your instructable is a definite keeper for me and when I get a chance I need to toy with the design and report back.

    Thanks dude. This is actually a simple speaker for beginners,all that you said about would just baffle them (just as it did me.)
    I know whatyou said is actually Great for the speaker.
