Picture of Munny Speakers
Give your speakers some extra personality by making them out of a vinyl doll. Kid Robot makes the easily hackable 7" Munny doll and I've been meaning to cut one up. The combined need for some new speakers created a happy union of doll and speaker.

Now, I'm not the first person to think of this. I've seen at least three different versions of a Munny with a speaker in its head. Still, the only one I've seen in person was just one doll for mono sound and the driver was pretty worthless. I wanted mine to sound at least decent and I'd say I surpassed that.

Step 1: Get a Pair of Munnys and Drivers

Picture of Get a Pair of Munnys and Drivers
I went to the Kid Robot store in SF to offset the $25 price tag by not having to pay for shipping. At the time I couldn't find any of the black Munnys online and kept calling till it was back in stock.

Each Munny comes with a few random accessories. A big pencil, a cape, goggles, all sorts of stuff.

The drivers are Tang Band 3" Bamboo Cone Drivers and have an extended range of 105-20,000 Hz.

Step 2: Trace the circle

I bought two drivers that are reasonably small at 3". This was pushing it pretty close to what would fit on the Munny and to be sure everything was where it should be I measured the diameter of the back of the driver and cut that out of card stock.

I then put this card onto the face of the Munny and traced out the circle.

Step 3: Heat 'im up!

The vinyl that the Munny is made of is pretty firm when it's at room temperature, but heat it up with a hair dryer or a heat gun and it softens up oh so nicely. After that the Xacto cuts through it like butter.

Cutting is all about careful subtraction. I cut within my safe area quickly, but when I was getting close to my line I started whittling down the space with constant checks with the drivers and eyeballing it from the side to see where I needed to remove more vinyl next.
Here are mine - white, though; the drivers I got for a steal - they are from some Logitech THX speakers I found at the Goodwill for $7.99; I also scavenged the amp from a powered set of Altex Lansing speakers from the same Goodwill. The problem I ran into is the magnets on the back of these drivers are enormous, so I had to cut down the vinyl at the top of the neck to get them to sit right.

Oh yes, those magnets get big fast. Nice job repurposing the drivers!
Absolutely brilliant! Here's a finished set I made my little sisters birthday; it's an ipod dock with sub and munny speakers :)

How do these look? I made them with 4 in. white Munny's. I am really surprised with the quality of the sounds, it's higher than I expected.

Wow, those are some tiny drivers there. Cool that it opens up the 4" category of vinyl toys as there are many more to choose from.

Congratulations! I love it.
Thanks for the idea and the guide.
I love my munnys!
I probably overlooked it, but what is the small circular one between the munnies? A tweeter?
the small circular thing is a volume and bass control knob from an old set of creative speakers. the subwoofer is also from the old creative speakers.
can you do a guide on how you did the whole thing especially the volume control?

Thanks
well basically i followed the instructables guide .

as far as the sub woofer and volume control go I simply bought a $80 set of creative computer speakers that had the proper wattage. (which i cant remember what it is anymore)

Then I tore down the creative speakers, pulled the wiring out of them and soldered the wires to the muny speakers.
I didn't have to do anything for the volume control, as it hooks straight to the sub woofer.

OK, so here's my take on this great Ible. Hope you like em. They match my MAC. I used 2 white Munnies and a Boston computer speaker set (BA635). They came out AWESOME and I think I might make a few more sets and gift them.

I like it. They look like tails.

Wow great job!

author credited obviously :)

Cool. I was thinking of making an STL of a munny that was ready for a driver to be put in. So it would have the opening as well as a flat ring with holes that the driver could be connected to without any need for glue.
I am working on that as we speak. I will upload both stl and obj files so that one can adjust the hole diameter to the speakers of their choice :)

Excellent!

You can also heat it up in hot water, if you don't have access to a heat gun or hairdryer. I've used water for reshaping miss-formed Vinyl parts many times.
redfoday big_F2 years ago
could you do it in the oven? if not do you boil water or just sit it in hot water?
could you use a hot knife or soldering iron to start a hole and use a dremel to finish it off?

I'm going to either try this out on a couple of 3" Vinylmations or 4" Munnys/Dunnys
What is a good cone driver size for a head (or body) of a tinier figure?

Any baffle step compensation or internal volume considerations?
WICKED! gotta try this
mara01922 years ago
could anyone give me some approximate dimensions of this munny doll. i'm thinking about making one but i'm trying to plan it out before i buy all the parts and spend a lot of money. i'm looking for an approx. dimension of the front of the head (where the speakers are), the size of the neck hole, just anything that might help. sorry for the strange request, just trying to save some money by not messing up
