High Quality Harddrive Speakers [Björk - Hunter]

Have seen people turning harddrives into speaker for a long time and finally dared to do it myself yesterday. However, I havnt seen anyone even getting decent quality before, but Ive come up with a way howto improve it alot, and here is how it sounds.
Björk - Hunter playing

Think its fake? Please visit my new video recorded 3 years after this one that shows some of the tweaking process.

how many ohms do you read on the coil?

don t you damage the amplifier?

@Theroumich

Hello. I read about 30 Ohm for each harddrive at the ends of the cables. I do not know if it damages the amplifier, but of course you should _never_ use an amplifier you are scare of breaking when doing experiments ;)

How is it exactly producing the sound though? where does the sound come from?

[FurreFurre]

@Matzoh09

The sound come from the vibrations that the strong magnet and the coil produces. Basically the whole harddrive is vibrating in the frequences the amplifier sends to it, and therefor, producing soundwaves from its vibrations, just like a speaker.

I could do the research to gain knowledge into how speakers work. But I'm telling you, this video is bullshit and I am not gonna waste my time. You however, might want to, with your infinite genius, give me a brief synopsis as to how these speakers work.

@Benzenering1004

Sure, same as a speaker... A coil and a strong magnet, as well as what in english I belive is called a diaphragm. Here, the harddrive have both a coil and a strong magnet, only thing needed to produce a good sound quality is some sort of diaphragm. I am using the table the harddrives are standing on to amplify the sound. Simple as that. As for more knowledge, have a look at Wikipedia for Loudspeaker.

i think that is the best explanation of it lol

finally someone that knows how to do it properly

nice video

@Theroumich Higher impedance reduces the amps output..lower impedance could damage the amp.

@FurreFurre About how much power do you need to make a noticeably loud speaker out of it? Looks like you have a nice home theater receiver behind them lol

[Theroumich]

@FurreFurre. fine.

an ampli work with 4, 8 16 ...depend of the capacity of the ampli... 30 ..is ok ;)

most of the time it s is 4 or 8

less than that would damage your ampli

i like it anyway...good video.

thx for the answer ..now i know the impedance of a HD :)

PS: i know any Geek experiment should be done on a "nothing to lose mode" :)
