Munny Speakers. (With Amp!)




About: 2econdhand maker and Teacher

I was inspired by fungus amungus's Munny Speaker instructable but thought that if it was to have a good sound then it would need amplifying. I bought a very cheap set of iPod/laptop speakers to supply the actual speakers and the amp.
This project could work great with a second hand pair of computer speakers.
You will need:
    Munny Dolls. (x2).
    iPod speakers
    Soldering Iron
    Craft Knife
    Philipshead screwdriver
    Insulated wire
    Hot Glue gun
    Vacuum Former (ok, so you prob dont have one but you will need a case for the amp)

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Breaking Things

The first step is to break apart the speakers. You need to careful extract the speaker cones being careful not to damage them.
The Amp circuit board should also be taken out if you are going to make another case to house it. If you can/want to use the existing box, then leave it all connected. In hindsight, I probably should have done that rather than go to all the effort of making a new case.

Step 2: Amp Circut

Remove the amp circuit and speaker cones. With Care!

Step 3: Template for Speaker

Trace around the speaker cone onto a piece of paper and cut out the centre.

Step 4: Trace Template

Trace around the template on to the Munny Doll's 'face'.

Step 5: Cut Hole for the Speaker.

CAREFULLY cut out the hole. It is very easy to push too hard and to over-cut.
Repeat for both dolls.
Test for fit and trim as needed.

Step 6: Install Speakers.

Drill a hole in the base of the Munny Doll
Bring the insulated wire up through this hole, through the neck and out the 'face'.
Solder wires onto the speaker.
Stuff cotton wool into the head cavity for sound dampening.
CAREFULLY glue the speakers in place and leave to dry.

Step 7: Make Base

I wanted to not use the bright orange case  so I decided to create my own.
There are Instructables on how to make your own vacuum former and I reckon they are a great addition to any workshop.
Larger Munny dolls could maybe house a battery pack and the amp circuit. Depends on the circuit.

Step 8: Assemble Base.

Drill holes in you base that align with the volume buttons, headphone jack and the on/off switch. I recommend that they are a made a little bigger that you think to allow for wiggle room when assembling.
Here I have installed the circuit and the battery pack.

Step 9: "Weather With You" by Crowded House

The Munnys now live on my desktop with the amp case trimmed down and hiding behind the computer.
If I was to make them again, I would use the large Munny Dolls and hide all the electronics inside the body cavity of the dolls. You could have volume and power switches mounted on their backs.

    Just thought Id share my Munny speaker system with you. Your Munny is a lot more refined. Mine isnt aesthetically finished.    I used an old PC speaker system.   I made simulated broken horns to mount the mid range speakers in. Then put all the electronics in an old plastic container. Made a make shift on of switch and volume knob. Mounted the electronics on the subwoofer, then mounted the Munny on the plastic container.   It sounds really good, and gets fairly loud.  I just cant decide what to cover the clear container and woofer with.

    Thanks. Yeah, it fills the house pretty good. Allthough the bass can overpower the mids, at least theres a volume controll for the sub woofer. Also, since I used a bunch of plaster and fillers to make the Munnys head, it ended up detatching and fell off in the summer heat. I ditched the body and mounted the head on a mic stand swivel. So I guess its not really a munny anymore.
    Anyway, thanks for the complement, and keep up the nice work.

    oh yeah.  I also made a sound port routed from the back of its head exiting through the teeth.  It made a noticable difference

    Just wondering: what is the frequency response on this or Fungus project ?
    Usually I try to find as much possible linear response output (at least 20 - 20000 Hz) as is available in a tag price from 2.1 smalls for laptop ( i hate included miniature speakers) to my dining system...
    That really depends on everyone taste but could imply damages to ears durring time.

    Stop being a tool and commenting on people who correct people. I haven't commented in months.

    Completely acknowledged Fungus Amungs's great project...just made my own one and wanted to create the Instructable for kids to follow.

    adding heat (heat gun) before cutting makes this step much easier.
