Does the perspex case make the sound less hideous?

This is awsome!! Im gona order some parts and build myself one of these just for the sheer geek factor… i mean hard disks look so cool without the covers on but its hard to find an excuse to have them lying around without purpose… maybe a ‘harddisk clock’ to go with it :)

why put so much work knowing about sound quality issues

I think this may actually be doable for me. I’ll give it a shot.

This has hack has been around for at least ten years. Google search harddrive speakers and you will find endless projects.

The actuator arm is mounted to a voice coil so it works for high frequency audio. You can also hook up the 3 phase brushless spindle motor as a speaker but it won’t produce much sound.

i wanna buy it!

cmon how much ?

; )))

What’s the point? an extremely inefficient sound producer that’s near 100% distortion.

I did it just out of curiosity when I ripped apart an old 40MB drive about 15 years ago. (The first dead drive I had which used a direct coil drive, instead of a stepper).

I just did it for kicks to see what it sounded like, but obviously I knew it wasn’t going to be a useful speaker. I can’t imagine why anyone would spend any time or money dressing it up?

Pretty cool as far as hard drive speakers go.
