Introduction: Portable Speakers / Speakers on Battery

Hi guys.
This is my first instructable. Enjoy!

So today I am gong to show you how to make from old pc speakers to speakers on battery.
It's pretty basic and I have a lot of pictures. ;)

Step 1: Items You Need

The tools you need:
-Speakers
-A cross screwdriver
-A 9v battery
-A 9v connection thing, see picture (don't know how to call it)
-A soldering iron (not nessecary)
-Pliers
-A hot glue gun (not nessecary)

Step 2: Open the Speaker

Now open the speaker using your cross screwdriver.

Step 3: Taking Apart

Now take the board what everything is connected to, and you will see a couple of wires: One for the otherspeakers, a pair for the wire of the speakers and one for electricity. Thats the one we need.
If you watch, u will see the electricity wires russing to the AC/DC adaptor, and then to your plug.

Then take your screwdriver, and screw the adaptor thing out.

Take your your pliers and cut the wires that are connected to the the two plastic tops.

Now turn your adaptor out and you'll see a sticker with the volt and the amp�re you need to use it.

Mine was: 9v and 0.6A.


Step 4: Connecting the Wires

Now cut the 2 wires that are leading to your electric board. Strip them.

Mostly, the left one (the first one) is + and the right one is -.
You also can check it using the volt meter.

Now mark your + and take the 9v connector, the red one is + and the black one is -.
Solder them together.

Then take some tape (I didn't find my electric tape, but duck tape will do the job ;) and wrap it around the place where the cables were soldered.

Step 5: Removing the Plug

Now we have to deal with that plug.
Its pretty simple.

Turn your speaker over.

Then take a nife or something and try to pop the plastic open that's holding the wire from the plug.

Step 6: Close It Up

Now attatch the battery to the 9v connector.

Use your hot glue gun if you want to make sure everything stays in place.

Then screw the top back on.

Step 7: Final

W00t!
Your speakers are now officialy portable. Tough mine are to big :D.

Now show everybody your new portable speakers, and add a comment :)


Thank you for reading folks!

I made a speaker that seems to have the volume of headphones since all I did was grab a speaker some cable a jack and I glued it all together but I don't like the volume it has. I want to add a litinium battery with the cable but I feel like that will fry the cable and speaker anyone know how to max the volume

how long does battery last??

i think 12 volt can make more higher until 24 v dc coz of the concern of the transformers coz poor quality mean lack of crank the boost of your speaker so can but should check the cap if the volt more over to 50 to sure your capacitor is not been explode and make your speaker not been unusefull

You sir are a genius. Detailed instructable, organized steps. I favorited it!!

This instructable is great but the 9 volt connection thing is called a battery clip. I am one of your followers because of this great instrucable.

Your instructions are great. Just wondering, did you detach the wall wart from the speakers all together? Did you hook up the battery right with the chip or did you attach the battery to the wall wart, and then to the chip. My speakers turned out to be AC not DC so I'm a little confused on what to do.

You have to get rid of the wall wart. Just connect the battery wires to the wires that are left from the wall wart. It'll just be a clean DC to DC connection.

are you danish?? its a danish/german plug.. if so then you will understand this DET ER BARE FOR FEDT!!! det virker fint men jeg bruger 12 volt og 2 9V batterier med end begrænser til 9 fordi det holder meget længere(jeg gemmer batterierne inden i)

its a european plug

i thought to hook up a 12 volt battery to it too, but the capacitor on the amplifier chip are rated 10 volt.. won't the 12 volt fry the caps..>?? although I checked the amplifier IC can handle upto 15 volts, but the caps concern me..

you are wrong: the voltages written on the transformer are the mean of the rectified wave or the equivalent DC voltage

OK!! Try plug in your transformer and measer by AC voltmeter..... or reattach a tranformer and check dc at IC... think you are worng not me.I haven't ever see tranformer that written a DC Voltage on it. From my 3Y experiean about Hi-End amplifier i dare to say you wrong about transformer.

those 2 wires are both + and -... the 4 diodes in the up/left corner are a rectifier so you cant wire a batterie to those wires in a wrong way

 By the way the 9v connection thing is called a 9v battery clip.

Ok, Thanks :)

I have a 12v speakers, but I dont know how what to do? Should I double the 9 volts? so it can work?

Hi John.

I think you could try to connect a 9v volt battery and check if it works.
You also can buy a 12 volt battery in a store (http://www.radioshack.com/product/index.jsp?productId=2049663).
Or if you dont really need your boxes you could connect them to 2 9v batteries and hope it wont get a over voltage.

ummmmmm i tried 9 VOLT AND IT DIDIT PICK UP SO THEN I TRIED A 12 VOLT AND IT WAS LIKE ALMOST THE LIGHT WAS JUST FADING OFF AND ON DO U HAPPEN TO KNOW A WAY TO JOIN TO 12 VOLT BATTERYS OR IF THERES BIGGER BATTERYS IN VOLTS

How much volt and ampere did you speakers required?
