earphone hub

Tired of sharing your earphones, and have to listen to half the music. But you don't want to spend money on it either.
 then this is a solution to it.


ps: I excuse myself for any spelling mistake that might occurred, English is not my native language. But please correct me if I typed something wrong, we're all here to learn.

Step 1: 1# what you'll need

-jack plug (from the cable of old/broken/bad earphones)
-jack socket (from old electrical appliances)
-wires
-(hot)-glue
-an attractive case to put everything in
-some drill bits and a drill
-pliers
-electrical tape
-a soldering iron is handy but not necessary 

the first step is to extract everything you'll need from the old appliances
since this is done by your own method and preferences (from destructive to poetic) I'm not going to show how to do that.

Would there be a way of just putting in a AA battery rather than a full blown amplifier, and solder it on to make the volume louder? and perhaps use a variable resistor to control volume... Or would that just fry things and create weird sounds?

Integrating a simple battery in the circuit is not the way to amplify a sound electrically. (or at least not that I know, but experimenting gives understanding) My guts tell me that the battery will just fry your phones.
If the car was a little larger, maybe a small amplifier would fit in, the schematics of small amplifiers can be found all over the Internet. But I had to remove an axle to be able to fit in 3 sockets, so there wasn't to much room to begin with, and I just anted a prove of concept :D

thanks, i'll do a bit o' googlin'

i LOVE the PUPPY !!!!!!!!!!! its adorable ^.^

Two earbuds consume twice the amount of volume as one, the volume will half, sometimes more, because cheaper earbuds use more power to have the same volume.

i didnt knoe that lolz ^.^ i lerned somthing XD

I came across that as well,
and indeed when I tested it with 3 bad earphones (free airline thingies that hardly work) the volume was a lot lower than with the better ones you see on the last picture.

just crank the volume up and it'll work fine. just remember to put it beck down again when one of the co-listeners is leaving the hub ;)

Yep,
The only problem I've ever had with this type of thing, is that if you have to very different ear buds, one can be uncomfortably loud, while the other too quiet.
I would hook one jack up to a pot, so you can plug the loudest set into that jack and turn it down.

[jakobus9]

indeed, very nice idea,
all three of them could be hooked up to a potentiometer,
the only down part is that the pots would also use up a little current, so then you would lose some volume in that.

it was just a quick an easy method. not something perfect ;-)

This setup would produce unattractive results, because every headphone you would plug into, the volume for the total # of headphones would reduce. Add more and more, and the volume would further reduce.

Taking it a step further and adding a battery powered amplifier and splitter would solve this.

[jakobus9]

there is always room for improvement

the question is
is there room for it in a toy car?

What is your native language?

Dutch (on the Flemish side of Belgium) ;-)
