Picture of Soup Cans!
For the purposes of a pun, "cans" are another word for "headphones".

Here's how to make audio-cans from soup-cans, and some other things.

Step 1: Parts & Tools

Picture of Parts & Tools
I used:

Two large soup cans (Lidl chicken, vegetable & pasta - it's OK)
One Scotch Broth can (Lidl, better than OK)
Two small speakers (4 Ohm)
A wire coat-hanger
Electrical insulating tape
Various bits of wire
Expanded polystyrene foam
PVC tube
Most of the electrical content came out of an old phone I bought a while ago.

A knife blade
A drill
Fencing pliers
A soldering iron

Step 2: Mounting the speakers

I held the speakers in place with two blocks of expanded polystyrene foam.

Wash and dry the soup cans thoroughly.
Press the cans onto the foam to give you a rough size to cut.
Cut circles of foam, but trim ~ half an inch off two sides, you'll need this to get the foam into the cans (see later).
Press the speakers onto the foam to give you a rough size to cut.
Cut enclosures for the speakers, in this case the rectangular holes grip the magnet assemblies.
Taper a round edge to accommodate the speaker-cone, and ensure there's room for wire to pass through the foam block.

Step 3: Connecting the cans

This bit involves the most hard work.

Untwist the coathanger and straighten it out as best you can.
Bend 2 x 90o in the middle to give a square turn through 180o.
At the ends of the wire, bend each around 90o and trim (I had to use fencing pliers on this - it was tough stuff)
Form 90o bends at each end, and curve the centre section to fit your head.

Run (electrical) wires across the the coathanger, securing with tape, these will connect one speaker to the audio input from the other can.
Whilst I was at it I incorporated two sweet-wrappers for reasons which should be obvious now if not later...

I've then secured the end pieces to the main cans with small sections of steel cut from another can.
Holes were drilled through both and the two pieces of metal connected with a pair of nuts & bolts.

In terms of the 'tinny" sound, have you tried using tapering glass cups? I used this with a mini-speaker plugged into my ipod, and it got so loud that I could hear it in every corner of my house and even outside for 20 feet. I actually had a neighbor ask me "What song is that you've got playing in there?"

Sincerely yours,

LOVE the first photo, dude. The glasses and the "cans" with the perfect goatee make you look like you should be wearing an aviators scarf and jacket, with the leather chill-cap under your arm as you walk away unscathed from a burning biplane. (Yes, I have an active imagination.) But seriously, EPIC!

This is clever. But can the sound fill a HUGE room?
lemonie (author)  Leemister4 years ago

No, just your head.

Oh. Well I think I might try this out. I collect headphones and stuff so, this will make it be alot cooler. THANKS!

It's cheap nourishment and that's about all that can be said about it...

that is just to cool :)
I had to give it an extreme "funny" rating. I wonder if lining the cans with e.g. neoprene would make them sound less 'tinny' Love your project!

 Its scary 'cause you look a lot like my Dad!
thats funnie i didnt know of the can term or i might of done my idea difernt , i needed a way to record right an left an contained that i could have room noise not interfearing , i put a mikeheadset with the speakers detached from the headband an the mike inbetween them inside a 32oz espresso cup an muffling stuffing all around them the wire comes out the straw hole , guess i shoulda instru. it befor all that electrical tape went on lol

They're not as stiff are they? L

This is actually an interesting idea, I would try mounting woofers the size of the diameter of the soup cans inside the cans, thus creating some potentionally ear damaging cans.
lemonie (author)  Punkguyta5 years ago
Yes, I have a pair of those, so I've got long-term plans for "Super Soup-Cans" L
Make sure they have some kind of vents in the rear of them so they don't act like pressure chambers :-S Btw, did you get my Pm lemonie?
lemonie (author)  Punkguyta5 years ago
Hi man, not yet I'm afraid... L
I'll be irate if my pm's aren't working either
