Before you start making the Speaker, make sure you have the following things :-

1) A dead Hard Drive (you can get it from a dead pc)

2) A proper Screw Driver (to open it)

3) Some wires

4) Wire Cutter or any other cutting tool

5) A audio amp (or a DVD with speaker outputs will work too)

6) Soldering Skills

That's it !!!

Step 1: Opening the HDD

Get your HDD (hard drive), & a proper Screw Driver for opening it.

*Please note that your Hard Drive may differ from mine. So pay attention to the parts in it, as they are almost similar.

Check out for the Screws in the image and open it carefully.

Don't forget to open it from both the sides.

Step 2: Opening It More !!

The Most important thing for the HDD Speaker is the Read/Write Arm.

We need to remove it for turning the hard drive into a speaker.

Remove the Remaining Screws as shown in the image.

In-order to remove the Actuator magnet after removing its Screw, make the use of a forceps or a flat pointed tool.

Use that tool to push the plate outwards and separate both the plates from each other.

Step 3: Removing the Arm

1) Remove the Screw of the Arm movement Limiter and remove it.

2) Push the arm away from the platter to take it out of the HDD. And Remove it by pulling outwards.

Step 4: Working on the Arm

This Step needs carefulness and patience.

1)The Arm taken out has a connector with it. But we don't need that Connector, so cut it out. The Arm is now free.

2)Flip it to get its two Solder points below the arm.

3)Also Cut the tip of Arm, as it will create Friction between the platter disk and the arm.

4)Now Get some thin and flat wires (we need two) and solder them carefully to these two solder points on the Arm. Don't let these wires Short. Be Careful.

Step 5: Repacking It Again

1) Place the Arm with wires, back into the HDD as you removed it.

2) Place all the Parts that we removed earlier (Arm Movement Limiter, Magnet Plate) back into thier place. Don't forget to tighten their screws.

3) Tighten the remaining screws as shown in the images.

4) Tie a knot of the wires to the Magnet plates so as to fix the wires (you can use hot glue too) .

5) Take them out of the Connector hole.

That's it !!! Your HDDspeaker is ready...!!!

Step 6: Testing It !!!

In order to test your speaker you will need a audio amplifier of minimum 2 watts Rms to hear it working.
Also you can connect it to your music system.

Here, in this instructable I had used a old Dvd.

1) Connect the wires of your HDD speaker to your music system properly.
2) And Let the Music Play...!!!




Watch "HDD Speaker" in action in the video........

<p>I Made it!</p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/MuU9ScHkrC4" width="500"></iframe></p>
<p>That's a simply great build ....!!! Good job !</p>
<p>i am looking for something that can record and or play music with something like the arm or a turntable. I suppose if you can have a turning disc right under th part now vibrating, it could &quot;write&quot; the music to be listened maybe with a normal turntable, can it work? What do you guys think</p>
<p>Trying this with a WD disc. Can't seem to find the 2nd contact. Is it under that glue dab?</p><p>Thoughts?</p>
it's above the bearing, a small point is visible. If there's glue present on it, get it removed.
send the picture of the glue dab...
<p>May I plug it directly to a cellphone?</p>
yes you can plug it directly to your cell phone....but it won't be that loud to give you a good sound....give it a try....
<p>what a lovely</p>
<p>I won't be able to get to this for a while but I am going to try it. I have the needed parts. :-)</p>
<p>Um, OK. </p><p>There must be something useful we can do with these. I just can't think of one now. But if you put a DC level into the winding, you have a pretty good positioner. Of course, that's what they were used for, but you can attach something else to them besides a magnetic write head. Hmmm, a mirror to deflect a laser. </p>
<p>Hello, author! Well done! And +1 to the jimvandamme's idea about mirror with laser.</p><p>If I am not mistaken flexible mounting of small mirror on the head arm will give something like Lissajous figures projected to the wall :)</p>
I tried out ....But with a single mirror , I jst got a straight line as it jst rotated left and right. You can think of displacement of a point on the X- axis, back and forth again. If you have another mirror, moving it up and down infront of the first mirror, it gave me a sine wave pattern......try it out...
<p>That's how an oscilloscope works, except it uses electrostatic fields to deflect an electron beam. </p>
The angular change would be rather small, but if you had two hard drives, you could deflect it in another plane too. Then modulate the laser... get some really interesting effects.
<p>Would it make any difference if I removed the discs? It seems like they would just get in the way. Perhaps I should experiment. Please advise, especially if I'm missing something really obvious. </p>
Yes you can surely remove the disk if you don't like it......I kept it coz it's easy to understand that it's made from Hard disk.....that's it.....try out your idea.....?
Off topic: I found a white packet in the hard drive, is that a water remover? And I also found a rectangular stick the had several stacks of some kind of cloth in it. Any ideas
that white packet is for moisture absorption.
Sorry, it's to capture dust as the air circulates inside the drive, very important in it's original application.
<p>i thought it was for small dust particles!, btw thanks for the instructibles</p>
and that stick about which you are saying, I couldn't tell about it untill I see it. coz I didn't get any thing like that in my HDD. ?
<p>OK, so there's not much of a bass for a woofer, but this is a good use of a dead hard drive! Ha ha!</p>
it has more bass....when you press it's arm with your fingers ..... you can feel it...the heavy bass....try it out....
I did this about a year ago,it's a cool project. Sound isn't amazing but anyway it's a cool thing to show to your friends ;)
<p>osum idea!</p>
<p>How does that work? I've taken apart more disks than I can count (data recovery... you'd be surprised what I can recover from a disk after a head crash) and never seen anything that I think would work as a speaker?</p>
<p>Oh, do elucidate! :-) How do you recover the data?</p>
<p>At work, we have a rig that we can put individual platters on, spin them up, and read the readable data, and make a bite for bite copy onto a second disk. Any data where the disk is scratched is lost, but everything else should be recoverable. Its an expensive bit of kit though, not something many people have, and its cheaper (and better) to just run a backup, so if your disk crashes, you dont lose any important data</p>
The coil of the Arm acts as the coil of the speaker (voice coil). As it is held between a strong magnetic field, it starts to vibrate and produce sound as soon as signal is applied.
<p>oh... thats really clever :)</p>
<p>Whoa!! This is incredible. I had no idea this was possible. Do you think I could adapt this to fit my Audio Junkbot Instructable? </p><p><a href="https://www.instructables.com/id/Audio-Junkbot/" rel="nofollow">https://www.instructables.com/id/Audio-Junkbot/</a></p><p>I used a hard drive for his foot, and I could rewire the speakers to play through the feet. Do you think I would need an amp? I'm not sure that the cd player electronics have enough power to drive the hard drive speaker. </p><p>Anyway, amazing work, I will definitely be trying this. Do you know anything about building an amp circuit just in case someone doesnt have a dvd player or wants to use this as a cell phone speaker?</p>
You can also give a try using the amp you removed from your cassette player.....Try it out....
Your BOT impressed me...!!!!☺ &amp;<br>yes....you need an amp for giving power to the HDD speakers. In case if you don't want to use a DVD player, you can use a amp too...<br><br>Make sure that it's power output is upto your requirements.<br>You can search instructables for audio amps .....<br>Even, I'll be soon posting a instructable on it...
<p>nice look like a turn table</p>
<p>This is so cool! If I remember correctly the head is actually touching the disks right? if so I wonder how rotating the disks would change the sound and or adding things to the disks to make effects on the sound. I see a new instrument being created here! </p>
The Arm is in air without any touch to the disc, in order to get proper movement. But as you said , if it touches the disc it will create different effects when the disc is rotated, but the scratching noise will be created...
<p>The head arm needs to be attached to a diaphragm to more more air. Its the movement of air that creates sound.</p>
<p>Great speaker. If you want to make it easier for people view the video, you can embed it in the page using the Embed Video tool in the step editor.</p>
yups I'll .....☺
