There are hundreds upon hundreds of thousands of D.I.Y articles on the internet, some more useful than others. I read maybe a dozen or so a day, solely for the sake of expanding my knowledge bank of obscure solutions. Every once in a while, one sprouts up that is just so damned simple, so face-palmingly obvious, that it makes me feel downright stupid for not thinking of it.
This is one of those.
The trick is simple. Armed with nothing but a pint glass, you can make the sound coming out of your iPhone (any smartphone should work, really – the iPhone works especially well because the speaker is on the bottom) about twice as loud. Does it sound beautiful? No. Is it a replacement for even the cheapest of speakers out there? Nope! But if you ever find yourself in a bind — like needing to blast a conference call just a wee bit louder — this little trick just might get you out of it. Check out the video below for an example.

I love it! So simple and can help in a jam.
Thanks for posting;)
Ugggh, the sound is horrible. Tried it with my Motorola Droid. It would come in handy….if I were trying to make people’s ears bleed.

i do the same thing with my sink in the morning when taking a shower. Makes my phone hearable with the water running.
Sweet! Daft Punk Alive 2007! Buy it, use it, break it, fix it,
Trash it, change it, mail – upgrade it,
Charge it, pawn it, zoom it, press it,
Snap it, work it, quick – erase it,
Write it, cut it, paste it, save it,
Load it, check it, quick – rewrite it,
Plug it, play it, burn it, rip it,
Drag and drop it, zip – unzip it,
Lock it, fill it, call it, find it,
View it, code it, jam – unlock it,
Surf it, scroll it, pause it, click it,
Cross it, crack it, switch – update it,
Name it, rate it, tune it, print it,
Scan it, send it, fax – rename it,
Touch it, bring it, Pay it, watch it,
Turn it, leave it, start – format it.
very nice solution:-)
I shall try it myself soon after my ongoing sync is ready:-)
haha… nice idea!
for the conference call – try using the earphones (just for the mic, which is then outside the glass/cup) and the ’speaker’ option.
bootstrapping start-up here, so always looking for ideas like that :)
Man if I had the know-how and the capital, I would develop the ” I-Cup”
Retails for $4.99 and comes with a charger in the bottom.
Upgraded models would have a directional swivel base to direct the sound and sell for $8.99.
Cool
Damn. Forgot to drink the pint first!
I tried this. It works. But sound fidelity goes to complete shit, like worse than the already shit speakers on the iPhone.
I always find the best thing is laying the phone on a table/flat surface with the speaker facing down. gives a wee amp boost.
