Clear Loud Cube Speaker

I took a battery box, one of those 10 dollar folding speaker modules, some epoxy and a plastic case from a dollar store metal puzzle toy. I thought it was cool because now instead of hiding all of the beautiful electronic components like the capacitors and the speaker cone cover.

Step 1: Materials and Tools

Battery box or holder
Amplifier circuit and speaker from a cheap speaker module, I used one like this (
Box for all of the above (I used a clear case from a dollar store Metal Puzzle toy

Soldering iron and solder
Drill (Drill press works best)
Small Drill bit
Sanding Drum (Belt sander would work to, and sandpaper would to, as long as you have a month set out to sand it)

Step 2: Prepare the Battery Holder

I got one of those battery holders that takes 4 AA and has a built in switch, you should use whatever your speakers use, mine actually used AAA's but AA's work because any normal "Lettered" battery (AA, C, D etc) will work because they are all 1.5 volts a piece. I used AA cause that's the kind of holder I had sitting around, just a hint, ifyou use the same cube as I did get a AAA holder it will honestly save about and hour and a half of work

1. Unscrew the little screw in the thick part of the battery holder
2. Pry off the melted down plastic rods to release the plate over the switch
3. Unsolder the switch and save for later
4. Pull the wires back through the holes
5. Saw off the part where the switch was hidden
6. Sand/File down as much as you can, if you can see it on the sides I sanded it down, I actually cut out

Step 3: Prepare the Speakers

I took the speakers completely apart, all 30 or so screws and removed one speaker and the circuit board, I clipped the wires to the battery holder installed in the original so that I could use my own battery box, then I soldered it to the battery box, then I epoxied the circuit to the bottom of the Battery Box

Step 4: Prepare the Case

I had to do a ton of work on the case to fit all of the stuff I wanted it to, I first cut off about a half inch piece of one side so that the battery box could stick out a little bit, I then filed down the insides to make it big enough for the batteries to fit, I also Drilled holes in the top to allow the sound to escape

Step 5: Rock Out

You're cube speaker is now done and it is quite loud for such a tiny speaker, plug it in and crank out the tunes, Also please rate and VOTE FOR ME IN THE EPILOG AND US OF EFFIECIENCY CONTESTS

    Pretty nifty. I built something similar to carry around on my 4-wheeler. I used a set of amplified computer speakers and a small 12vdc gell cell. I thought what a shame to cover up all the nifty stuff but i needed water proof / mudproof. Find yourself a schematic for an LED light organ and hook it up in there. they flash to the beat of the music. By the way if you ever get your hands on an old lcd monitor there is a nice piece of plexi glass behind the glass screen. Good job.

    I like that idea, I don't think a clear speaker on a RC car would look anything but weird but if it works for you that's good, and about the LED organ I almost did that, It actually had 2 ports cause it originally had 2 speakers and I wired up an LED to plug into it but it would only light up dimly even when it was at full blast, and I know basically how it works, you need an NPN transistor a power scource and a shifting voltage source IE a Headphone cord

    I'm glad you misunderstood me. My four wheeler is a honda foreman 400. but i do have a traxxas r/c monster truck. Now i have a use for the tiny speakers i pulled out of a lcd computer monitor. This is gonna be cool. Thanks for the idea.

    Ok, I was picturing it just sitting in the bed of a truck and bouncing around, could you post a picture of it, it sounds cool and also you're welcome

    I'm in the middle of buildin another one. my friend came out of the mud bog all crazy and killed my cooler and my jam box. i was laughin too hard to get mad because his 4 wheeler ended up in the fire we had built. i'll post the next one when i finish it.

    oh 4wheeler like fullsized, that is really cool, I thought it would look weird on an RC car, esp since there's not much room on them to begin with, and you have a cooler on your ATV? Sounds good


    for an rc car use a spy ear, some little speakers, and tap into its power, then your rc can have music just like the real cars!

    Thought about it, actually tried to use the other speaker output to drive an LED but it required too much power and I'm not too good with amplifier circuits, but I could wire it up so an LED runs of it and then just coat it with some aluminum from a can

    Check it out now, the pictures are much much clearer, it took the super macro setting on my camera and no lighting (Weird) but as you can see it looks 10,000 times better

    An Olympus FE 360 but my favorite camera was my kodak, the olympus takes better pictures but the Kodak had a thing on it where you could save a video clip as a photo, and it also had more on camera editing, Sometime before I go off to college I would like to get a touch screen kodak, the other things I like is that they take AA batteries (instead of those batteries that are expensive and take forever to charge) and it uses an SD card which would fit in my computer without a card reader but nice camera still
