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 issue

I'm not sure if this is the right place for this topic, but I am having a bit of an issue getting a speaker to work. I don't know the specifications of the speaker because it came out of an old toy. (The speaker is 2 inches in diameter.) Here is a picture: http://i55.tinypic.com/sgmts1.jpg http://i52.tinypic.com/2ekqb5w.jpg I want to know if there is a way to solder head phones to it so I can plug it to my Ipod.

DIY Speakers

I gave up my B&W; speakers that I've had since I was 16, which was a long time ago. I'm now in the market for some DIY speaker ideas. There are a bunch of speaker Instructables, but I would like to do something new and hopefully unique. Does anyone have photos of what they have built for inspiration?

Directional SPeaker

I saw a youtube video of a guy who built his own directional speaker (actually I remember it as a directional megaphone as he would talk into it, and it would target a person). I was wondering how easy it would be to do this? Can we build one with household material? Thanks for being awesome guys!

Turn laptop speakers into aux speakers

My laptop just died and I took it apart. The speakers have a 4-pin connector, which I would like to splice into aux and power to make an aux enabled speaker I can use. How do I do this? Pics: https://goo.gl/photos/PdyBhVxXLBfJfL3Z8 Thanks and RIP laptop. A little eulogy, because why not: Dear laptop, you will be missed. I had you for 5 years and you were a great machine. I took you apart and put you back together. We had a great time together and you lived a long life. I hope you have a great afterlife as a set of speakers, external monitor, hand warmer, and many more projects. You will be missed.

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.)

What is this? (speaker circuit)

I found a pair of broken speakers in a junkyard a while ago and wanted to take the good-looking connectors. When I removed them from the chassi I saw that there was a circuit board on the other side and now I wonder what it does. At first I thought it was an amplifier, but there is no connection for power or batteries. I made some schematics of the circuit, I hope that will help. Gogo gadget, internet community intelligence!

Opposing coil speakers?

Today's speakers have large heavy magnets, but what would be the result of setting up two coils which create opposing fields, one being the typical voice coil, the other being a replacement for the magnet.  Why isn't this in use today, is the power needed to create the required field just too great? This method could be used to increase volume while not overloading the voice coil right?

Series or Parallel speakers?

Quick question guys. I have two speakers I extracted from a laptop, and I need to use them for an iPod. The loudness is the goal here. So what's best for the volume - attaching them in series or parallel? Does it make a difference? I don't have time to get an amplifier, for it's due tomorrow morning, and I didn't think about using speakers until this morning. Thanks!

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.!

Amplifying speakers and IC's

I have come to the instructables forum today in search for knowledge. So I have been working on a simple speaker system for my ipod shuffle, the speaker I used is quite old, but was the only one I found laying around. When I plug my ipod into the circuit everything works fine the only problem is that it is barely audible. Is there a way to amplify the sound so I can actually hear it without having to stick my ear right next to it? Pictures of my work so far will be provided. Oh also identifying the IC's included in the gallery would be of utmost help. Thanks in advance.

DIY Wifi Speaker

Hi everyone, I'm not a native english speaker so sorry for my language's level. I'm new on the forum. Watching amazing DIY projects on Instructable make me want to do same things. I have a old 5.1 audio kit : http://www.amazon.com/Logitech-Z-5450-Digital-Speaker-970181-0403/dp/B000AM6QHO One of a rear wireless satelite is broken. I tried to fix it but without result. So my new idea is to use this stuff to make something like Sonos Audio products. 5 independant wifi speakers connected to a wifi network to stream music, and most important to sync sound of a movie streamed on TV. In an other project, i want to create my personnal NAS / Media Center with Plex. In fact i want to create a system, to stream video and sound wirelessly from a Data Server. Is it possible ? My knowledge is not very large so i need your help to improve my skills. I saw this product  but maybe i can find a other solution, more easy to build and cheapest. http://fr.aliexpress.com/item/Wireless-Wifi-Audio-Receiver-music-streaming-receiver-Supports-iOS-Android-Airmusic-DLNA-AirPlay-Qplay-Music-Radio/1993464174.html I want to create something easy to connect with a only centralized system/app. Do you think it's possible ?

Turntable speaker with piezo speaker glued to make-shift horn? Answered

I'm wondering if I could take a piezo speaker, glue it to the bottom of a make-shift gramophone horn, and wire it directly to the RCA output cable of a turntable. Would this blow the piezo speaker?

Converting HP laptop harman/kardon speakers to external speakers?

Hey, I just tore apart an old HP Pavilion zd7000 for the speakers (nicest laptop, nay, compact speakers I have set ears upon) and was wondering how I'd go about hooking them up as an external speaker (3.5mm input) with the option of either battery or wall power. I suppose I'd need the input voltage, a variable resistor for volume, and a switch for power. I'd also need to change the red/black and blue/black wires into an 3.5mm female audio jack (red is left channel, blue is right, and black are ground). Of course, it can't be as simple as that... help me out, please! I apologize for poor photo quality. All I have is this iPod, and the camera's not quite the best in the world. The big black panel is attached to the right channel for resonation reasons, I believe, and the small tube (not seen) on the left is for bass boosting. Update: I've tried hooking them directly to a 3.5mm jack, as user Re-Design suggested (thanks!), but there's a lot of clipping, and it drains my iPod's battery like crazy, so an amp is a must. Would the amplifier out of some old PC speakers work?

Bios speaker randomly beeping? Answered

I finished building my computer a while ago, but initially removed the BIOS speaker as it kept beeping. Not a full alarm like if it were overheating, just a pathetic little "bip" every 10 minutes or so. The speaker is connected properly and it is the one that came with the board, and it makes a proper beep when I turn the computer on. I have disabled the CPU fan warning as I had it connected to my fan controller instead, and I also have thermal sensors on everything and everything runs nice and cool, so I honestly can't figure out what the problem is. I thought it may have been my dying hard drive, but I have replaced it now with a brand new hitachi 500gb sata-II drive that runs smoothly and I still get the problem (it just went off again whilst tying this). Any idea on what could be causing this problem and how to fix it (without removing the speaker). I have also tried it on Ubuntu and Windows, and I get the same problem, not that it should matter.
