Picture of How to wire a headphone jack to a speaker
Photo 9.jpg
I was trying to figure out how to do this for a very long time when I finally figured it out by piecing together different pieces of information I found in many different instructions. This helped me a lot and I hope it helps you with all of your speaker projects!

You Will Need:
A speaker (I got mine by taking apart an old computer speaker)
A pair of iPod earbud thingies you don't want back
A soldering iron or a bunch of electrical tape (I used the electrical tape but soldering would probably be preferable)
Scissors
A wire stripper (you can use scissors for this if you don't have one).

Step 1: The Earbuds

Take your earbuds and cut the wire right below where they split, so you have a plain cord with a jack on the end and a split cord with the earbuds on it. Take the plain cord with the jack and strip about an inch of the insulation off the end without the jack. There will be four separate wires, a copper, a red, a green, and a red and green striped one. Burn off the colored insulation on these wires by setting them on fire individually using a small lighter or match. The flame should catch, burn off the insulation, and burn out quickly. Do this to each of the wires, making sure you can identify their original colors still (leave a bit of the color at the base so you can tell). Set this aside and grab your speaker.

hey for the speakers, do they need to have batteries? or can just a simple speaker without batteries work when soldered with a headphone jack?

They don't have to have batteries to work. I did it without them.

depends on the ohms and power needed by your speakers, results varies, mines is running on a 9v battery.
can u tell me how i would hook the 9V?
Hey, it's me again. I'm connecting another speaker set to install in my backpack. Could you explain how you connected the speakers to the battery, and to the headphone wires? I have looked all over instructables. The only battery powered speakers are hooked into amps or pcbs. My speakers are not connected to anything - all I have are just the actual speakers. I would really appreciate any help.

Thanks.
your talking to me? if you are , its easier to email me at kyismaster{AT}gmail.com
You may need to use diodes.
you don't need to have batteries, just keep in mind that that means it will be using the power from your iPod.
i would like to object, my Ipod can't power my 300 watt subwoofer can it now. My 500w Amp can barely keep up. the speakers vary, and ultimately rule over this.

Ok, I am kind of old school, and don't usually keep up with renaming of electronic parts. However, unless some names was changed, the "jack" is actually a plug. The jack, when I learned electronics, was the hole this plug fit into. As I said, I don't make a habit of keeping up with electronic parts that have been renamed, or the names were switched.

Aside from this, good instructable.

For best results for this method without an amp you should use a 8ohm speaker. It stil will not be terribly loud but a it louder.. These speakers are typically found in a computer case, You can buy them on Amazon or your Local Radio Shack. The bigger the speaker with the bigger the magnet will require more power.. The power used on this is based on the output of your output method.. The ipod or average MP3 player does not put out much power in the 1st place so an AMP is mos likely required. There is no wire combo that will make it any louder as the output is still the same.

Hey man, you wouldn't happen to have a wiring diagram for the CVC would you?
how can i make it louder different wiring??
or where can i get the little amp that you are talking about and how much is it whats it called???
my speaker has a little white thing with two holes in it at the end of the wires what is that??

For those who have the means to build them there is a few good ones on here that give you the wire diagrams and 10-30 plus pieces and circuit lay out to build them.

For those who want one but do not have the means or no how to build them I build them one for $20 shipped that is 1 watt and very loud. They have Volume switch and run off 9volt battery. I am working on my new model that has a rechargeable battery and blue tooth. I just built one for a friend for his Guitar and it still needs the on/off switch/Light to show it is on or off and a case but this will give you an idea.

If you have the means to build one, The cost is right around $15 to build one and that is ordering the parts online. Your local Radio shack will cost you about $30 total and depending if they have all the pieces.(Radio Shack is expensive but in a hurry a good resource). These little guys are very powerful and are about 2x2x1 in size.. If you have G+ i have detailed pics step by step on building them.. I need to add it to this site,, I just joined this site the other day..I am not trying to spam this post, Just offering to people who really want one but do not have the means to build them.. Heck I don't even know if these types of posts are even allowed..

Huh? I think you are asking questions to the wrong person, but I might be able to answer your questions. Attach some pictures and I'll see what I can do.

I accidentally cut all the existing wire off the speaker, how would i go about soldering the headphone wires on?

I connected two speakers (some tiny ones from RadioShack) to my headphones. They work perfectly. First twined speaker wires together, then added headphone wires to each bunch of twined speaker ones.
oh by the way, the "volume" often varies based on the amount of electricity given to the speakers by the source. Ex: My phone - low/moderate Old ipod classic - high You get sound based on power
how much power do you need to make it loud???
do you think an ipod touch(3rd gen) will play some 8 watt speakers loud enough?
Sorry for the delay - I really do not know... You would have to know how much electricity your ipod puts through the headphone jack.
you probably already knew that...
Ok I have a question im hoping someone can help. I have 2 very large speakers that are about 40 years old still works basicly band new. I don't know how much power they need, but I hooked up headphone jacks to them and it works but the sound is very low. I wanna be able to hook up a power supply for them both. inside the wall. I don't wanna have to hook in to main power supply for the house. I have a 12v Dc 7.0 Ah spypoint battery. ment for sky cams, basicly going to frame it in the wall flush with the fall. I wanna hook up all the connection I need to hook up to the tv, iphone and 2 more speakers for 5.1 Surround sound not 2.1 sound. so im hook up the ports I need on a panel im going to make. the main question is where do I put the power at? + - right into the speaker or what, that parts I cant seem to find without someone saying use an amp. I don't have that kind of money and I know I have the spair parts needed to make it just don't know what to power up, no diagram about it or circuit layout. someone plz help

Dud.... I m working on building amplifier which recieves input from my phone and feeds them into a small 2" speaker povered by 9 v battery....

I connected the circuit but am not understanding 1 thing...
I bought a new earphone and removed its wires..(coz such wires are not available in my area) then i stripped the insulation of left earphone.. I got tho wires inside..
I m not understanding where to connect those wires to input of amplifier .... So please comment on how to give inputs to that amplifier...
I mean.... I got 2 wires.... One red and one copperish colour...on breaking left earphone.... And other 2 wires... Red and coppr again... An breaking right earphone... amp circuit diagram says that red of left earphone to be given to pin 6 and red of right earphone to pin 7... What to do of remaining teo copper wires??

Apparently i have successfully installed everything.. and it works.. the only problem now is that the volume is not quite the same with the it before it was broken down to pieces..

Anybody knows a solution on how can i amplify the speaker to its full extent?
Hey, i did this with a LG headset and a ihome speaker and it worked perfect except for the fact it is way too quiet can anyone suggest rewireing or somthing?
i made it and connected with my nokia e5 and it was nokia cable only which i have used but its playing music in the speakers very low voice i can only hear it when took it near my ears i used a 1watt 5ohms speaker plzzz helpppp

I done this with an 80w hifi speaker my cd player broke and I wanted to keep the speakers gave it a whirl and it's great no battery power or mains just runs normal plugged into my iPhone would like it a little louder but it's fine for what o need and 100% portable :)
sjones252 years ago
just finished doing this to an 80w speaker running it only off my I phone works great not mega quiet but I would like to get a bit more noise did you manage to solve that?I dont want any plugs or bAtteries involved 100% portable

My headphones are two cables stuck together. Imagine them like this = and it one of them there is Copper and Red wire and the other Copper and Green. Any ideas? Im not to sure about step 3 thats why i asked. And i am trying to connect it to a little sub type thing that roughly 2 inches across with positive and a negative wires running off it but there are silver wires in each cable. Thanks

ITS FOR SUPER NOOB!
I'm doing something similar using a set of headphones that are inside of a military CVC tanker helmet taking the helmet and turning the entire thing into noise canceling headphones thank you so much for this

Can you use ducttape instead of electrical tape?
yes you can. i just did it with my sub!
