Introduction: HEADMUFFS - Headphones Earmuffs
Perhaps not quite so useful in the summer months, but what do you do when you're out in the cold of winter, or maybe late on a clear night, and you want to enjoy your music without the awkward and uncomfortable hat+earphones? make some muphones! or muffones.. or headmuffs.. its up to you :)
Since i made these i found out they have already been thoughtof :( as has the speaers-in-a-hat i also made a while back (though mine had an mp3 player builtin ;)) See: http://www.hearmuff.com/
This is my first instructable, and i'm making these for my girlfriends birthday.. go nerd presents!
Step 1: Tools and Parts
First you need your tools and equipment. you will need:
A pair of ear muffs
A set of headphones (supra-aural or circum-aural)
A set of earphones, for lead replacement (optional)
A soldering iron (or gun)
Glue (plastic glue or superglue - not shown)
And possible a kinfe/scissors/clippers.
Step 2: Mounting the Drivers
After taking apart your donors and extracting their organs, including the drivers from the headphones (de-soldered from the wire), the lead from the earphones and the earmuffs, you need to mount the headphone drivers (the speaker bits) into the casing of the earmuffs. Mine already had a hole pretty much perfect for the skullcandy lowrider drivers, so with just afew small shavings taken off of the plastic, they fit snugly into place.
Remember to get them pointing inwards! Then add a little glue to ensure they stay where theyre supposed to. i used plastic model glue (Airfix type plastic cement) but superglue would probably work just as well if not better.
Leave this to dry, then proceed.
Step 3: Wiring Up
First, make a hole through the furry outer part of the ear muffs to thread the wire through. Draw the wire through this hole and loop it through a hole or tie a knot to prevent the wire pulling on the soldering whilst being worn.
Solder the tips of the wire to the drivers. one side of the driver will normally be marked with ink or a '+' stamp, ensure that you are consistent with the wiring, i.e. the ground wire goes to the un-marked terminal on both speakers. this ensure they are in phase, so the sound is correct when listening.
Step 4: Protection & Covering Up
To prevent the diphram of the drivers being dampened, causing a tinny quieter sound, we need to ensure nothing is touching them. To do this, use the original covering, but trimmed to just fit over the edges of the speaker. i used angled clippers, but many other tools would be just as appropriate.
Glue these covers around the edge and place them ontop of the speaker, taking care not to get any glue on the diaphram or any porous or foam type materials, including the thin layer of material on the cover, as thiss will break down the plastic and usually cause it to form a ridgid solid. Let the glue dry.
Step 5: Re-assembly
Finally, replace the foam into the fur, insert the plactic containing the drivers, and replace the top layer of material. pull the wire tight, and you have your new cosy headphones! you can cut a circle in the top foam layer, in front of the speaker, to allow sound to travel through better, but i have left it as it is. they are extremely comfortable, and still very warm, and dont sound bad at all!
