Coffee Cup IPhone Speaker
Intro: 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.
- Draw a dot in the center of the bottom of the cup
- Use that as a guide for placing your earbud against it
- Trace the shape of the earbud
- Cut out a slightly smaller shape
STEP 2: Stick the Earbud In
Shove the earbud in from the back and keep it in place with a couple pieces of duct tape or, as pictured, gorilla tape.
STEP 3: Add a Couple Toothpicks for Legs
The speakers needed to be pointed up so I attached two halves of a toothpick to the bottom with more tape. Not too sturdy, but enough to try it out.
STEP 4: Test!
Thanks to randofo, I was able to use a decibel meter to check the improvements in volume.
The first test I did was to put the meter right at the mouth of the cup. I compared this reading with a measurement of the volume coming from the other earbud at the same distance. The height of the cup was about 5" so I measured the earbud from 5" away as well.
The difference? Huge! The cup speaker was about 15 decibels louder than the naked earbud. Pretty impressive, right?
Well, no, not really. That would be assuming that your ear is right up in the cup and if you're doing that you might as well just be wearing them.
So time for more testing...

STEP 5: More Tests!
Next I moved the meter to 11" and 18" away from the earbuds to see how effective it would be if I was sitting near it.
The results here were much more down to earth. At 11", the improvement with the cup was about 3 decibels for the cup. At 18" it dropped to about a 2 decibel improvement.
Basically, the sound was a little more focused and louder if you sit right in front of the cup. It's a bit of work for little volume gain, but it does look funny and pseudo-effective and to be honest that's pretty cool.
And yet... none of this really matters because, if you haven't guessed by now, the sound is crap. Pushing the earbuds to full volume leads to distortion even when you're close to them. Adding some air between you and the earbuds makes it sound even worse. For now, I'll be sticking to my current desk speakers.

I'm wondering if anyone has given credit to the guy/gal who first put their cupped hands to their mouth to amplify sound?

By putting the phones at back of cup (not dropping in), you get more sound and some amplification. A Bose Wave Radio and tuba have bent gradually enlarged sound tubes (pipe organs have long unbent ones), this allows for louder and directed sound.
There is a very nice explanation for it and I can't remember it, (too far back to High School)

I ask this question here as there may be sound centered people who remember this guy,(me thinks it was a guy).
There was a web site a number of years ago where a gent recorded vibrating telephone poles/wires. He gave instructions on How to build the listening pick up, he was trying to get the sounds of "singing" telephone poles from across the world.
Does anyone remember him/her, and have the url to his old site?
Then we may be able to use WayBack Machine to find it!
Please cross post this request across the web so it can be found, send an email or post it here.
I think it was a hoot, and would like to try it
thanks
Have a great day,
( don't get caught)

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.

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?

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