Introduction: Homemade Speaker

Homemade speakers are fairly simple and easy to make. I got the idea to make this when my brother had to make a speaker for physics class and well i decided to make an instructable for it. So here it goes...

Supplies Hardware

X1 Electromagnetic wire Wire Strippers

X1 Regular disposable drinking cup (NOT Plastic!!) Electrical tape

X1 Paper plate 12" (for sub woofer) Soldering skillz and equipment

X1 Small Paper Dixie cup 3oz. ( for tweeter) Hot glue gun

X3 Semi-powerful magnet

X1 boom box (something that has red and black ports for speakers)

You also need some 3 ft.x 1ft. plywood and nailing materials

X6 Rubber bands...

Step 1: Cutting the Paper Down

You need to make both the tweeter and mid range smaller in size so you need to have a two inch base for the mid and a 1/4 of an inch base for the tweeter

Step 2: Wrap It Up!! (not Really)

Now you need to start putting the electromagnetic wire into coils. You need some left over wire so you can solder it onto more wire (like 5 inches).

Step 3: Glueing It Together

Now you need to halve the rubber bands and glue them on to the sub woofer, mid range and the tweeter. The sub woofer needs 6 halves, and the tweeter and mid range needs 3.

Step 4: Soldering

For the connections all you need to do is solder them like so.

boom box & connection wire & connection wire -> tweeter coil-> connection & connection wire -> mid coil -> connection wire & connection wire -> sub coil -> connection wire & connection wire & boom box

legend
& = twist together
-> = solder
if confused look at the pic

Step 5: Making the Speaker Box

Cut holes in the plywood and leave about a one inch gap in between the board and the paper plates
hot glue the rubber bands to the board have them tight but not too tight so they cant vibrate

Step 6: Connections

Now were almost done!
The red and black connectors at the back a boom box should be able to click up and down...
Click them both up and slide one connection into the red slot and one into the black slot it shouldn't matter what connection goes into what slot.

Step 7: Finishing Up and Performance Enhancements

Now turn on the boom box with some music stand up the plywood and put the magnet close to the wire and enjoy your music making creation.
In order for your sound to get louder and better quality try these things:

-Use a larger gauge wire for the midrange and even bigger for the subwoofer

- If you have a multimeter try to match the impedance of the stereo with the impedance (resistance) of your speakers, if you are unsure of the impedance of you sound source make the amount of wire wraps equal 8 Ohms

- Wrap the wires neatly and glue them evenly to the plates

- Make sure that your sound system can put out enough power for the speakers but make sure the coils don't get hot

And if you still aren't satisfied with the sound quality don't use paper plates and use something that is meant for speakers, or just buy some speakers

There is no sound even i connect the wire to coil.

Put a magnet on the board and the coil on the speaker or reversed.

no because it needs to be able to vibrate

author
LexanPanda (author)squirt85002011-07-10

Actually, it'll vibrate just fine even if they're glued in place. With the rubber bands, they have more freedom of motion and can be theoretically louder, as well as better sounding. Just make sure nothing is scraping, or you'll get some nasty buzzing sounds.

WERE IS THE MAGNET

author
squirt8500 (author)s omer2011-06-27

I didnt show it but you can hold it behind the coils or you can rig something to hold it there

Unitrix (author)2009-09-26

Couldn't you just twist em all together? What's the difference between soldering and twisting the wires? don't you get the same result?

author
squirt8500 (author)Unitrix2009-09-26

ya but soldering give a more secure connection

author
Unitrix (author)squirt85002009-09-27

so soldering all wires gives better sound quality right?

author
hitachi8 (author)Unitrix2011-02-07

no .

absolutely no difference .

author
squirt8500 (author)Unitrix2009-09-27

ya

author
squirt8500 (author)2010-10-10

yes, and yes it would do the same thing

author
squirt8500 (author)2010-10-08

the speaker is more proof of concept so it isnt very loud, no, you cant subsitute a copper cylinder for the coil

author
jj.inc (author)2010-04-24

Now that I have finally got to this I have one problem.  It isn't loud enough.  Right now this couldn't even meet laptop standards.  Do you know if increasing either coil size or magnet power would fix the problem.

author
squirt8500 (author)jj.inc2010-04-25

 Either getting thicker magnet wire or doing fewer wraps of the wire would make it louder, i am adding a new section to the instructable for performance enhancements so check it out

author
jj.inc (author)2010-02-17

 Could you add pictures of the magnet

author
squirt8500 (author)jj.inc2010-02-18

 You should just be able to use any magnet, even a strong refrigerator magnet should work.

author
lolbutter (author)squirt85002010-04-07

I also would like to see, but mainly because you are not very clear on exactly where to put the magnet(s). Even a paint drawing would help.

author
squirt8500 (author)lolbutter2010-04-18

 you have to do some experimentation before you get the distance right because every coil is different so if you have a magnet just turn on the speakers and find the optimum distance, it should be less than 2" away from the coil

author
lolbutter (author)2010-04-07

So does any copper wire that is jacketed work? I have some 16 gauge PVC jacketed copper wire, and I would like to use it. That should work right?

author

jj.inc (author)2010-02-17

 so is the electromagnetic coil just wire or is it magnetic special wire

author
squirt8500 (author)jj.inc2010-02-17

It's both, the core of the wire is just regular copper wire but it has a enamel on it that electrically insulates it from the other wires so that it doesn't short out.

Great job! I made even more simple speaker: rgawron.megiteam.pl/2010/02/11/home-made-speaker/ but it sounds pretty quietly.

author
wingchangwow (author)2009-11-14

could this be turned into a subwoofer?

author
squirt8500 (author)wingchangwow2009-11-15

I doubt that it would be loud at all, but you could try!

author
knektek (author)2009-11-08

thanks for this instruct' i have just found 2 magnets that looked a bit like speakers but without the speaker coil so thank you for showing me how to make speakers

author
pyrorower (author)2009-10-30

I have been trying to find an instructable on how to make an actual speaker for a while now, thanks a bunch!

author
Sparrow40k (author)2009-10-25

Can you make this easier to do, like add more pics and all. thanks like it so far. Blake

author
squirt8500 (author)Sparrow40k2009-10-25

 sorry i did this a long time ago and dont have any extra photo's, but if you have any questions i'll try my best to answer them

author
Sparrow40k (author)squirt85002009-10-25

Great!, first of all. Does this work like a real speaker(like my computer speaker.)
If so..
Will plastic party plates work?
To copper wire is that just sticky taped to the back?
Are there magnets?
That's all now..

author
squirt8500 (author)Sparrow40k2009-10-26

* Yes but you should probably put a resistor inline with the coil as to not blow it out think something low though
* Plastic plates would work but i dont think it wold sound as good
* Yep
* Yes but you have to hold them near the coil, you could make a jig to hold them though

author
Sparrow40k (author)squirt85002009-10-27

Cool, thax. In a little while when I get some spare money I will get this project started.

By sauder, I think you meant solder.

my bad

zimmemic25 (author)squirt85002008-09-07

would u please edit the text, because i was really confused until i saw this comment. and btw: wasn't there a youtube/metacafe video? or is there another instructable about making speakers/subwoofers from paper plates?

author
SKULLOK (author)zimmemic252009-04-23

yea, it was different though. On youtube, they said all you needed was a paper plate, some aluminum foil, a shiny penny (because a non-shiny one would cause resistance... according to the guy who posted it) and a jack+wire. Mythbusters tested it, I knew before he even finished making it that it would never work, as you need magnets to create reverberations... running electricity through a penny (though it would conduct electricity, as it is copper) does NOT create reverberations... if electricity + copper made sound, we would be deafened on a daily basis, and there would likely be constant humming noises coming from the walls. This, however, uses a magnet, so it may work, though I can't guarantee it would sound any good.

Household Hacker is stupid. Almost none of their ideas work. Try Kipkay.

author
ccav (author)SKULLOK2009-05-19

Wrong Look up "electrostatic". One wire. You could also use thermal energy. Two wires, heats the penny, penny heats aluminum foil, expansion and contraction produce sound. From watching the HH video it appears he only hooks up the signal wire, leaving the ground disconnected, creating an electrostatic speaker which would work when horizontal to ground, but maybe not so well in vertical position. So mythbusters did 2 things wrong off the get-go. However, had the penny been firmly bonded to the aluminum foil and sufficient current available, the speaker still could have worked using thermal energy. It's responsiveness would have been limited by how quickly the aluminum could dissipate the heat generated by the penny, and how well the speaker was sealed.

There is on youtube by household hacker but it uses a penny

author
Shadowfury (author)prodlad2009-01-23

Fake. You can not have a speaker without a magnet and a coil. The penny made a horrible substitute for a coil, and there was no magnet at the back.

author
ccav (author)Shadowfury2009-05-19

See my reply to skullok. You do not need a magnet to produce movement with electricity. See jl naudins website for electrostatic lifters. Look up electrostatic energy (why capacitors "pop" when exposed to high currents) or the electrostatic can crushers.

author
OneManUniversity (author)prodlad2009-01-19

it has been confirmed that its a fake- I don't think you can make a speaker without a magnet or coil.

author

wait are you talking about my instructable or the household hacker cuz if you are talking about the house hold hacker disregard my previous comment

author

Oh I'm talking about Household hacker- yours works fine, great 'ible.

ok thanks i shall be deleting my previous comment
