    Why on earth would you imagine that "headphones stuck to a tin" would make any kind of acceptable speaker?

    Hi,

    Show us what you've done so far and somebody will probably pitch in.

    so far ive dismatled each head phone and attached it to a piece of metal. I need a way of increasing the sound out of each head phone. Some kind of small audio amp that i can attach to the headphones if thats possible

    Hi,

    Oh Gee, I thought you ment a tin for building the amplifier into... Well, if your teacher is a good sport with lots of compassion, I'm sure he'll give you an A (for the effort if nothing else)... That is if he doesn't hurt himself when ROTFLHAO ;)

    All that assuming it's metal shop or whatever, but if it's an electronics course...

    Sure you can't rip a small loudspeaker from somewhere, like a PC's internal speaker ? .. Hey, what about the PC you are using to write here ? (Nobody is going to notice that it's missing :)).

    Amplifier w. LM386
    Or try Google: Headphone Amplifier Schematics

    It ain't gonna sound sweet though, something like Donald Duck on drugs, but thanks for providing us all with the laugh of the day :D

    Gutted headphones mounted on bits of a tin... Tsk..Tsk... I fear that image is gonna stay with me for a long time.
