I have decided to begin a unique experiment and somewhat daunting task this weekend. My end goal is surround sound and bass for my cell (okay, not really surround; just two satellite speakers.) I don't know yet if I'll pull it off. As much as I know about computers, I do not know electronics well at all. It's going to be a lot of experimentation.
The two satellites are already made. I cobbled then together with a set of old headphones, two ice cream pint containers, two toilet paper tubes, and a bit of plastic wrap. I cut out a hole in the bottom of the pint container to fit a toilet paper tube snugly through. With the lid of the container I cut out all the paper inside the stiiffer ring. I pulled the plastic wrap tight across the top of the open container, and then fit the ring on so it looked like a drum. I pushed the toilet paper tube up against the plastic to focus the sound.
I have taken this contraption and rubber banded it over my headphones, which have been separated in a way that I can place them about eight feet from each other or connect them as headphones again. The sound created is very clear down to about 100 Hz. The plastic is like an amplifier, while the container is a kind of resonator for a richer sound.
The woofer I'm making will splice into the same line. The box is a 6 x 6 x 10 octagonal tube. I need to make my own speaker coil out of leftover wire from busted earbuds (for $1 you don't expect quality). I also have to make my own cone to resonate the vibrations between the coil and the magnet into sound. The back of the tube will be covered with taut plastic wrap to make the bass even fuller. When finished it should sound quite nice, assuming my less-than-amateur skills amount to anything.
