Coffee Cup iPhone Speaker

This speaker set is made from a regular pair of earbuds and a paper coffee cup. This is inspired by these cup speakers that made some noise in late 2008. I always thought that they were a cool design and playful and wanted to try it out to see if it was effective.

To be fair, the original creator admitted it wouldn't be when he said, "The increase in volume, of coarse, is radiculous, but hey, you get stylish iPod accessory out of nothing!"

Still, I figured why not try it out and just see hear what happens. I have an old pair of earbuds that I can try it out with and a couple coffee cups that were just hanging out on my desk waiting to get recycled anyway.

Step 1: Cut a hole

This step is easy enough.
  1. Draw a dot in the center of the bottom of the cup
  2. Use that as a guide for placing your earbud against it
  3. Trace the shape of the earbud
  4. Cut out a slightly smaller shape

This was an easy to follow tutorial. Kudos to anyone who actually came up with the idea

It allows some more room in the cup for the sound waves to bounce off of before it leaves the cup, I believe.

Why not use a cheap pair of old school headphones?
jedi_knight says: Jun 23, 2010. 10:38 AM
just out of curiosity how loud is it?

Very easy to follow steps thanks.

ummm, i did the exact same thing in slideshow format a while ago, I love your work, and subscribe, but a little credit would be nice

I hadn't seen yours before. Besides, I did give credit to the original place I saw this idea in the intro. That one was posted online several months before yours.
Aztof in reply to fungus amungusApr 25, 2010. 9:42 AM
I originally got my idea from a short article in one of the (fairly) recent issues of Make magazine, which (and i don't mean to troll here, but) i believe precedes the website where you got your inspiration for these speakers.

i've been doing this for at least 7 years with Styrofoam, paper, and plastic disposable cups.  when ever friends came over and we wanted to listen to music, we did this.  i only had a CD player so this made it possible for more than 2 people to use it at once (not very well mind you but better than nothing.
in fact one of my friends did this with his "hit clips" (www.warpbreach.com/8/hitclips.gif for those that dont know what they are)  

the idea is not very original and its more of a "poor mans" solution if any thing else.  saying this is your idea is like saying you invented how to shoot a rubber band off your finger.

hopefully this does not come off as rude or mean.  i'm just trying to clarify that credit for this is imposable to give and MAKE did not come up with the idea.
fungus amungus (author) in reply to AztofApr 25, 2010. 2:02 PM
And the idea was probably done before that MAKE article. Regardless, I cite my inspiration and have no concern with any other prior art since none of it directly affected this.

Not sure why it matters since the whole point of this Instructable is that there's no point to doing it. Who cares who came up with the bad idea first?
john12345172 in reply to fungus amungusMay 1, 2010. 6:14 AM
 Honestly, I bet people have come up with this idea long before the Make magazine did. It's not that complicated to think of. In fact, I almost made this from a completely original idea a couple months back.

And as long as you cited the place you got it from, you're fine.

Good idea, stupid implementation, this is a mono speaker, stick both ear plugs in so that you don't miss half the song. Or, make 2, and have a stereo setup.
fungus amungus (author) in reply to roland985Apr 19, 2010. 7:20 PM
Um, thanks? It's an OK idea, but the point of the whole Instructable was to test it out and see if it was worth doing. The results are that it isn't. Why waste time making two bad speakers?
roland985 in reply to fungus amungusApr 19, 2010. 8:56 PM
Mount it near your bed so you can go to sleep without waking up with a pair of mangled earbugs in the morning. Or you could just buy a dock!

I love it!!!!
dkfa says: Apr 14, 2010. 11:40 PM
2 very similar instructables were posted wayyyy back. One by me and a other by some other guy.

Wouldn't this be copying?
fungus amungus (author) in reply to dkfaApr 16, 2010. 12:56 PM
You might want to reread the intro. It is copying, but not of your idea.
bigfunkychiken says: Apr 15, 2010. 5:36 PM
very nice and easy-to-follow tutorial. good job!!!

What do you use this for?

Goodhart says: Apr 13, 2010. 8:37 PM
Hmmm,   am I allowed to "fiddle" with this, and try something, pretty much different, but end up with the same device? 
fungus amungus (author) in reply to GoodhartApr 14, 2010. 7:17 AM
Why are you even asking for permission? :)
Goodhart in reply to fungus amungusApr 14, 2010. 3:30 PM
I mean, for the contest......as for permission,  well I was having a bit of a bad day yesterday.....very anxious, a bit paranoid;  tis a bit better today....but I just didn't want to "step on any toes" with what might be viewed as a "stolen idea"  :-) 
fungus amungus (author) in reply to GoodhartApr 14, 2010. 3:59 PM
"Stolen idea"!?! Pffft. This one is itself a stolen idea with the addition of some further testing as to its effectiveness. As kelseymh pointed out, attaching drivers to cones is hardly new.

Go nuts. Unless you copied each picture and bit of text without adding anything at all I really don't care. I care more that you'd hold back from doing something because of this.
Goodhart in reply to fungus amungusApr 14, 2010. 4:08 PM
Ok,  let me see if I can get my old piezo element to make some noise again ;-)

Where did you get the decibel meter? How much? I've always wanted one!
illdoyourdrugs in reply to XOIIOApr 13, 2010. 8:19 PM
Do you have an Iphone or Ipod touch? Theres a few decibel meter apps. One comes with Appzilla, a 50 in 1 app, which i def recommend. I don't know how accurate it is though!
XOIIO in reply to illdoyourdrugsApr 14, 2010. 12:01 PM
iPod touch, and i would rather spend money on something made to do the job. Apple makes cruddy microphones
fungus amungus (author) in reply to XOIIOApr 13, 2010. 11:04 AM
I borrowed it from Randofo. It's from RadioShack and costs $50 new.
XOIIO in reply to fungus amungusApr 14, 2010. 12:08 PM
Sweet, I'l have to get one online sometime.  
noahw says: Apr 13, 2010. 11:09 AM
Maybe this is how you do it...

Yes! The answer is always buying more stuff.

Javin007 says: Apr 13, 2010. 8:14 AM
Argh!  This is what I was going to do (though doing it a bit differently).
noahh says: Apr 12, 2010. 8:22 PM
Dang, this is what I thought I would submit. This is well done, though.
mattthegamer463 says: Apr 12, 2010. 4:52 PM
I did something like this in high school physics class, except we wound our own coils and placed a permanent magnet in the center.  Can't say much for sound quality.

This is a wonderful experiment for kids to learn about sound and magnetism simultaneously.  Very cool.

 the main pic looks brilliant. I might have to do this with my pair of broken earphones. It'd look nice
