Introduction: Cardboard Boombox (made for an Mp3 Player or Ipod)

Supplies:
THE RIGHT SIZED CARDBOARD BOX
EXACTO KNIFE
SCISSORS
RULER
SPEAKERS
OLD PAIR OF HEADPHONES
HOT GLUE GUN AND DUH THE GLUE STICKS
A LITTLE EXTRA CARDBOARD
SOLDER (SO U CAN CONNECT THE WIRES)

My First Post (BE KIND PLEASE!)

Alright so i had a monday off no school, yay! i had a lot of extra time and i had just taken apart a boombox u know to see how it all works.. anyway after i was finished trashing that i had two perfectly good speakers (the boom box was a sony like from the 80s)...so i thought to myself .... why not make a speaker box that i can plug my old mp3 player into... (gettin out ear buds gets quite annoying)....

I Know Finding A Box That is the right size is going to be harder than this actual project so if you are among the lucky few that do let us continue...

First i cut 2 holes in the top of that cardboard box.... after taht i applyed electrical tape to the edges for looks and so it dosn't apear to be cheap but who are we trying to fool here ............. its made out of cardboard

The next step i suggest is to get your old pair of head phones and take out the speakers (removing as much plastic as possible) you can then connect your music player to the head phones and leave the music playing..... apply the leads to the speakers u want to go on your box, to the two wires that lead to the one headphone speaker... to test it and see that your speakers actually work.... it may take a while to get it just right. you can connect both sterio speakers as i did to the one head phone speaker, look at the photos and u may understand. (hope so)... now that u've got the speakers working (assuming that you did) you can solder teh wires together (you might need to recrute a friend to hold the wires in possition as you solder them together, its very difficult to do by yourself) keep the music playing the whole time because if teh speakers arn't connected properly it will only come out of the one head phone speaker...

AFTER you have accomplished that you should glued the speakers on to your box were u see fit..... i put the speakers facing out so it would project the sound out of the box hehe what a novel idea........

OK THE HOME STRETCH ......the last thing i did was i hide the wires under a piece of cardboard so i didn't have to fight them and get everything tangled up ..........

IF YOU MADE IT HERE CONGRATS!!! hey and send me a message i want to know how helpful my instructions were and how many people did it.

i'm sure the pictures will help more than anything .. i hope i got enough detailed ones.......... sorry i didnt take any during the building process;(

Hi, I just wanna ask if whats the function of that two circle things glued between the two speakers,,

ok what your doing makes no sense the way u have it the speakers would not be very loud and y do u need the headphone y dont u just chop the wire on the headphone jack and connect that to the big speakers

hi i still don't get how u connected the headphone wire to the two speakers. can u check this image and let me know if it is right or not. if it is not can u draw somekind of a diagram so that i can see it or post it with the instructables that you have Thanks

Wiring it like that will mean it will be mono and both speakers will be driven off the same channel so it will be quieter. There should be two sets of wires (one for left one for right) so just connect one speaker to each one and it will be louder and stereo

author
BigCommieNat made it! (author)BigCommieNat2007-12-06

that way is wrong... well, to be more specific, what you have there is two speakers wired in series (and if i'm right... phase inverted) the headphone cable should have 3 wires... red, white, and unshielded. Red is the right channel positive, white is left channel positive, and the unshielded is negative for both channels... or ground. So, connect red to the '+' on the right... left to the '+" on the left (if the speakers aren't marked i think it's usually the bigger of the two terminals on the speaker itself) and then jumper the two '-' terminals.. and connect the unshielded wire to the jumper. unless you want mono sound (which is close to what you have described)

I am seriously stressed out due to the fact that I can not build a REALLY REALLY simple Guitar amplifier amp... I did have the idea that if you do the following connections, SWITCH>JACK>JACK>SPEAKER>SPEAKER>+9V>-9V-SWITCH Current gets amplified and powered by the 9V battery. Hmmm...

author
cornflaker made it! (author)cornflaker2009-05-12

Will not work, if you want an amp you will need to use some circuitry. There will be some instructables on here that tell you how to make a simple amp, but what your saying is too simple (I understand where your coming from but trust me it wont work (and yes i did try that when i was much younger and just getting into electronics))

Hey one thing I wouldnt keep my mp3 player that close to the speakers the magnets can erase the hard drive. :P

If you used the Make Mp3 player, it uses SD cards, so no worries about magnets :P

Most mp3 players nowadays ( ipods and generic types ) are flash based, so unless you using a hd player u should be fine with the speaker magnets

i can't get my speakers to hook up to my headphones. i've tried with three different headphones and two different speakers. 1. i-pod headphones with one green wire and i red wire both in the same strand. 2. cheap headphones with one blue wire and one copper wire, and on the other strand one red wire and one copper wire. 3. cheap headphones #2 with one red wire on each strand and 6 smaller grayish shiny (steel?) wires on each strand as well. I have tried every configuration of wires on both portable 2" radio speakers and 1 3/4" singing card speakers. Each time I give it input coming from my i-pod mini. Each speaker plays fine when tested against a battery. And each headphone set plays fine when reconnected with the headphones. I'm frustrated as to why it won't work. Help?

When you write a guide, don't use leetspeak Every time you wrote "now that u've got the" it made me cringe It's "you have" or "you've". Don't bother writing a guide if you won't use proper spelling and grammar.

author
SonicKidGJ made it! (author)SonicKidGJ2008-07-13

Yeah. It's just terrible grammar. Also some people consider shortening words like so as texting language or whatever. Leetspeak is using numbers.

i am currently working on a set of old stereo speakers i had modified to fit an eighth inch jack for my ipod however, the only problem is i have no idea how to rout a power source. as of right now it draws current directly from the ipod itself and becuase of this it has much less volume and consumes the battery of my ipod. if anyone has some schematics that apply to this could they send them to me.

As far as volume goes, it all depends on the size of the box and quality of the cardboard and individual source... so many variables. It would, however, be much better with and amp. One question though: Why don't you just cut the wire on the headphone plug, strip it, and wire that to the speakers? Another VERY important thought: CHECK OHMS! Make sure that the impedance rating on the speakers is the same as that of the headphones or GREATER. If it is lower, you risk drawing to high amperage from the mp3 player, potentially ruining it. And, you should throw away the headphones. Use the plug: it has 3 wires. One should be black or un-insulated. Connect it to both speakers' - terminal. Each of the other two go to each speaker. Do not get sloppy on wiring; you could end up with some pretty funky current draws. Great Idea though... like the thriftyness

I made one with a cord from other speakers with a headphone jack i did not quite know what you meant by attaching them to one speaker from the headphone so i didnt and it still works, ALL OF MY WIRES ARE HIDDEN AND MY IPOD COMES OUT THE BACK SO IT DOESENT GET MESSED UP BY THE MAGNETS

well i just soldered the wires to the speaker because it was easier ....... i could have cut teh wires .... adn prob. will in the future but as of now i'm satisfied w/ it

author
crapflinger made it! (author)2007-01-18

what was your reasoning behind leaving the earbuds still attached to the wires? i'd think that leaving them connected would add un-needed resistance to the circuit...you'd probably get better sound out of the big speakers without them

author
wes_711 made it! (author)2007-01-17

in reply to the people who said its not loud enough .... it can really really crank out the noise (yes and amp would def. help tho) ........... and this was the first time i ever soldered anything so i didn't want to mess up anything (i'm only 16) ..... but anyway thanks for all the replys!! i'm really excited about finding this website its reallly awsome
