They may seem fairly "crappy" and the speakers they included with them are shitty, just normal headphone speakers, maybe a little larger than average but nothing special. I wanted to up-grade the speakers with something maybe a little bigger (the ones in here sound pretty okay tho). I tried to see if these small surround sound speakers I had would fit, and the magnet is about 1cm too deep so that's out of the question unless I want to remove a whole lotta plastic with my dremel.
So I had a second idea, what about using pager/cell phone motors (would ps2 controller motors work? I have lots of those) and either having them receive the signal directly which I'm sure wouldn't do much unless it was a small pager motor with a small voltage requirement. But, what about a simple circuit, kind of like this mod which uses the sound output of a PSP to drive a circuit that uses "seperate" voltage (ie battery pack) to drive the motor to the sound.
My general idea is to have a pair of headphones that feel like you have a giant subwoofer strapped to your head. I know it can be done, I know the circuit isn't that complicated, but probably has enough parts, can someone help me get a jump start on this? I'm sure modifications to a pair of headphones is fairly straightforward. Also any suggestions on a new type of speaker that I could install would be appreciated.
