Okay I’m in school to become an engineer; this would never work.

You guys have some potential to be really popular.

Please stop mixing bullshit and serious cool stuff.

If you really understand how a speaker works, this doesn’t make a lot of sense. Actual speakers pass current through a coil of wire causing a nearby magnet to vibrate. This vibrating magnet is attached to a diaphragm which amplifies and produces air vibrations and creates the sound that you hear. Nice try, but not very well thought out.

@bikerxgames540: You sound like you’re all mad because you fell for it =) Your average person who sees this video wouldn’t be so pissed off. Cool it, and try to come up with better lies ^^ Yelling at people who are never gonna read what you have to say doesn’t make you cool, in fact, you just look like more of a jerk lying and calling them fucking retards.

As for something relevant, I just tried this one day out of boredom. Cut up the wire from some old headphones and tested it. It was fun =P Didn’t work but oh well.

And you fail due to ignorance against major electrophysical laws.

1.) There is no way to get a penny to virbration by applying current to it – no matter how shiny it is. The penny just works as a resistor and even that isn’t a job he does well, because it is made of copper and this a fairly good conductor. In fact you are producing a nice and clean SHORT CIRCUIT which could possibly damage your mp3, computer or whatever.

2.) Even it this WOULD work, you used the wrong cables to do it -> you used the 2 inner cables which are carrying the two stereo-tracks (yeah … headphones are made of TWO speakers), what leaves you with 2 similar alternating signals. In laws of acoustic and electronic those two erase each other.

3.) Even if you WOULD have wired it correctly, those 1,5 Volts coming from a regular headphone-jack would be simply be waaay to silent for hearing purposes. Example: If you would like to have about 1,5 Watts (which can’t produce such a loud sound), you’d have to have a current of 1 Ampere (!). If through that cable would flow something with 1,5V and 1A (which eqzals 1,5 Watts), you would soon have your nose filled with the tasty smoke of a melting insulator and a burning wire. (Don’t worry: no mp3-player could reach a current like 1 A).

4.) If everything would work (ignoring those physical laws, ignoring the fact that the signal coming from the headphone-jack is to silent, ignoring the wrong cable-job), It would sound like totally crap – so there is no way to call this a HighDefinition-Audio-Speaker.

u would have a better chance useing a mini speaker (kip kay instructional vid) and puting it in a big plastic bol(srry cant spell) coverd with ceram rap to increase the vibration
