Instructables

Low-cost portable speakers & 'amp' for the iPod (non-electronic megaphone)

Inspired by these two instructables, I get up my ass to make my first instructable by myself.
Ghetto Headphone "Amp"
Quick Easy Speaker Amp

See for yourself how good it is functioning in the video.



Does this sound familiar to you:
You are in a hotel or you stay anywhere else without a sounddock oder soundsystem for your portable mp3-player but want to listen to some music or an audiobook until you fall asleep? The Earbuds are to quiet for one or two people to listen to. And - believe me - you didn't want them in your ear all night long, at least of all not sharing them with another person.

I was sick of let the earbuds hang into an empty wineglass to amplify the signal. Not least because of the fact, I didn't got a wineglass everywhere I stay. So I remembered the old an not such fancy technique of the fluestertuete. Please be patient with my English and with this Instructable. It's my first one and I know it's not the trickiest of all on instructables.com but I read all these instructables and if there is only one of you, who find this useful, I am pleased.

Thanks.

What you need is one (mono) or two (stereo) sheets of paper. Probably you will find a sheet of paper everywhere - the bigger, the better but it should be in DIN A4 or letter at least.

Step 1: Get it. Roll it.

Get a sheet of paper (size does matter, but letter is okay.) You can use the hotels letter paper, a newspaper, foil, almost everything you can roll into a cone-form. And sure this is the next thing, you got to do. Roll the paper you got and make a cone out of it, maybe by putting your hand into the roll. You'll figure it out. The only thing important is that the hole on the smaller side has to be nearly the size of your earplugs.

Its so simple, thanks great idea. I wonder if I made a larger funnel, say using a tin fabric it might be even louder?
knarx (author)  Scriptone5 years ago
Yes, it will get louder. But maybe the sound will also be a bit more metallike. Thanks for the comment.

I don't think it can get much tinnier ;)
It sure will. In fact, you'll have made a Victrola.

I've known this trick for a bit, so I wont comment on it, but I really like your English, like at the end instead of saying glue or tape this together, you said fuse, which made my day.
