Question by sir-zeke   |  last reply


Hey you guys are all so creative and knowledgable, this site is so great (tho terrible for my procrastination) does anyone know how to build a speaker to fit certain dimensions? like how flat could i make a speaker, and how loud would it be for something only a half inch thick (if thats possible) and up to 12" wide? it is meant to plug into an mp3 for power source etc.

So I saw this in the ad, and thought it too good to be true. Are they nearly decent? I don't need anything fancy, just something that doesn't sound crappy to the untrained ear. And if the normal speakers are crap. Could I just use the sub?http://www.bestbuy.com/site/olspage.jsp?skuId=7784926&st;=7784926&type;=product&id;=1142290023793

DIY Speakers

What we did was took different types of copper wire to find out which was the best for the quality of our speaker. We tried a wider gauged wire, a longer, and a couple other unsuccessful hypothesis´. The best one was the longer wire. About 1 meter long.  The things you need:  -copper wire -av cables -box without the lid -magnet from a speaker -av cables -stereo to connect to the av cable -tape to put you copper on the box

Speaker on the blitz

I moved all my stereo equipment around a month ago or so. And I noticed that my speakers never sounded the same as before the move around. Today I got a little fed up with the shitty sound they had, and apon turning my balance on my mac to the left, the music sounds very tonal. It's not very bassy like my right speaker. If I turn it over to the right speaker it sounds normal, and shakes the room, but the left one does not vibrate my room worth 2 cents. I even switched the speakers around to see if it was my left channel on the amp, and it's not, it's the speaker. Anyone have any ideas why it sounds like this?? And yes, it was hooked up correctly, I did try switching the wires around, and it sounded worse, so yes it was connected correctly. These are technics twin woofer floor speakers, thought they were decent but my faith in them is very little right now. Thanks guys for anything you come up with.

Turn passive speakers into active speakers?

Hi, I finally got around to starting the Altoids Tin Guitar but I have a problem: I have no amp. And an electric guitar is kind of useless without an amp. I figured I could use some old computer speakers but I realized that they are not powered speakers. Is there any way to turn passive speakers into active speakers? Or at the very least is there any software I can download that will let me hear the guitar on my computer as I play? I've tested the piezo (attatched to the 1/8" jack with an audio cable.. I forgot what you call it, but it's the kind that has two plugs) by plugging it into the mic jack for my computer and holding it near my acousic guitar while I strum. I can record audio just fine but I can't hear as I play. Is there any software that would let me do that? (A demo is fine with me.)

Amps and Speaker Sizes

I read that regardless of the size of a speaker connected to an MP3 or something, the sound output should remain the same. I assume this was incorrect because using large computer speakers seems to disprove this. Is this because the speakers have more surface area and generate more sound? So will using large speakers at max volume drain more energy than small earbuds at max on the same music player?

Making speakers louder?

I'm totally new to sound systems, and I'm using an old pair of computer speakers. These computer speakers have no volume control, they were controlled completely by the "Volume Control" icon on my taskbar. I'm currently making a stand for my iPod (I know, real original) and I want it to have speakers. Only problem is that it's not very loud. When hooked all together, I think my earbud headphones at full blast are louder than this speaker at the same distance. I'm wondering if there's a way to add power to these things to make them louder. Any ideas are appreciated.

Cell phone speaker?

So, y'know how sometimes you might feel like sharing your music with friends, but you dont want to share you headphones? The solution would be to carry speakers, but usually they're sort of bulky and they wont fit in your pockets very well. So, what about cell phones? even some that are maybe a few years old are still smaller then some speakers. Everyone knows taht cell phones can be Really loud, so what if we somehow add a cable to attach to an audio device, and switch around some things inside, and use the dead phone as speakers?! I would try and do this, but i have no idea how, so this is just an idea for you peoples to think about.!

Matching speakers to amplifier

I have purchased 2 Maxamp20 amplifiers (http://store.accusafe.nl/modules/versterkers/maxamp20-met-3-5mm-connector) and i am trying to match speakers to them, i've searched audio forums for information (that i mostly don't understand) and tried asking questions (that have been mostly ignored) and i think i've found appropriate speakers but i want to get a second opinion before i purchase stuff i might not be able to return. i don't have the space for and can't afford the weight requirements of a large enclosure but i want fairly high volume and wide dispersion so im looking at getting 2 of these PA horns (http://www.specotech.com/index.php/products/audio/item/542-spc40rp) to mount on top of a shallow down firing enclosure for 2 of these subs (http://store.accusafe.nl/onderdelen/luidsprekers/subwoofer/dayton-audio-sd215a-88-8-dvc-subwoofer-speaker). i know the subs work with that amplifier because they are used in Boominators (http://www.diyaudio.com/forums/class-d/104402-boominator-another-stab-ultimate-party-machine.html) but i have no idea about the horns. also assuming this setup is okay do i need some kind of filter or crossover (not sure of the difference) to split the sound safely between the midrange and the sub speakers?

Making a set of iPod speakers from computer speakers.

I have a set of stereo computer speakers that run off a 9v power supply, I'd like to replace this power supply with a bank of 8 1.2v cells (9.6v) that I could recharge with the original (9v 94mA) power supply. First of all, would I need to regulate the voltage down to 9v, or will 9.6v be fine on a simple amplifier circuit? Secondly, would I need any circuitry to allow the 9v supply to charge 9.6v worth of cells? Would some kind of auto cutoff circuitry be necessary to prevent overcharging of the cells, or would common sense by not leaving it charging for long periods suffice?

portable phone speaker/mic

Ok, so I have a portable phone and would like to create some sort of hands-free speaker/mic for it. I'm not sure how to go about doing it and I'm not very internal-electronic-savvy (i.e. chipsets, soldering etc). Ideally, I would assume it should be connectible via the 2.5mm headphone jack. I have an old 2.5mm headset. It's got an ear bud and flexible arm microphone and connects via 2.5mm jack. I should also have some old computer speakers lying around somewhere. I assume that's all I should need. I would like the microphone to be part of the device and be functional, but not sure if it will pick up my voice from a far distance. I'm not too concerned about looks/style, but would be a nice addition. Functionality is my first concern right now, although I do have a few old Fossil watch containers that I could put the speaker(s) in and some sort of dock or rest for the portable phone would be nice as well. If soldering is involved, I will need very detailed instructions. Thanks again! I hope someone can help me. If someone knows of a fairly inexpensive product, I would be willing to buy (since I'm not very soldering-savvy as I said above), but I think this would be an interesting project to build.

Old headphones made into speakers

Hey guys. If you want to cur the crap skip to the third paragraph. So I found this speaker in a voice recorded message greetings card thing and it's pretty loud for it's size, so I decided to put it in place of a headphone on my old iPod headphones. I Took apart the right bud and soldered the + - wires to the speaker, and it worked first time. My problem is now that some songs have say guitar coming through the right speaker and bass through the left. I decided to try and mount the speaker below the split. The thing is, I'm not sure which are the + and - wires. I know that speakers work by changing between + and - to make the diaphragm move, but when I mounted the speaker where the ear bud was, it was easy as there were 2 wires. Below the split there are 4. So my question is. Does it matter what 2 wires I pair together to solder at one port? The colours are Blue, Red, Green, and Red/Green intwined.

Portable Party box (A.K.A the toolbox speaker)

Hello all, recently I replaced all 11 speakers in my car since after 15 years or so they all had developed dryrot and stopped working. As many of you are aware however car speakers only come in pairs so I was left with one perfectly good (and expensive) speaker when all was said and done. So not wanting it to go to waste I devised a plan- I would use it to make a portable sound system. I went to amazon and purchased a dayton DTA-1, this little T amplifier runs on AA's and puts out 30 watts. Now all I needed was something awesome to contain this all in. Luckily during my  daily commute to school I stumbled across a rusty old craftsman toolbox left out at the curb to die; well needless to say its been given new life. Look at the pictures I provided to see whats what, but my basic plan is to mount the speaker in the lid by building a cradle for out out of plywood, cut to fit the inner contours of the box. I will then secure the board in place by using adhesives as neccisary. I also plan on painting the wood so it matches the toolkit. In the spirit of keeping things as utilitarian as possible I dont want to deck the thing out too much, but if you guys have any suggestions as to what else I should include in the build id be glad to hear them. (Leds, decoritive touches, ect.)
