Need to screen speaker magnet?

I want to put a small speaker *inside* my PC wired to the sound
card.

I will use something like a 2.5 inch diameter speaker.

What problem arises if the speaker magnet is not screened?

Will items like hard drives or floppies be adversely affcted?

it shouldnt cause any problems. not so long ago all pc cases came with a
normal type speaker fitted rather than a buzzer/beeper

If you have the room, how about something like this....

Nice idea. However, calling it a "stereo" speaker kit just because it
has 2 speakers is stretching it a bit when the speakers aren't farther
apart than your eyeballs. You'd have to be very, very close (like
pressing your nose up against the case) to get any stereo separation.
But if all you want is some sound that moves with the case without the
hassle of toting around speakers and routing their wires then, yeah,
it's a solution, I guess. At that point, however, I'd just use a pair
of headphones. I already do that at work. Imagine the cacophony if
everyone at work sitting in the cubicle farm had speakers.

Just remember you won't get lots of sound pressure (i.e., volume) from
that speaker. The sound card doesn't have much of an amplifier to be
driving unpowered speakers. It's okay for headphones because proximity
and occlusion only require minimal sound pressure.

It's been a long time since I used passive speakers (i.e., they've been
powered for a long time). I remember back several years there might be
a jumper on a sound card to select line-level or amplified output, or
there were separate outputs for powered and unpowered speakers (where
powered was the line-level output and unpowered was amplified for the
unpowered speakers). You needed to use the amplified setting to get any
decent amount of juice out of the sound card to power an unpowered
speaker. Do sound cards these days even have an amplified setting?
Aren't they all now line-level outputs?

If you're using the box in a quiet environment and you don't need much
volume, well, then maybe hooking an unpowered speaker to the line-level
output of the sound card might work. Like I said, it's been ages since
I used unpowered speakers and I don't have any spare speakers around to
test right now.

Easy enough to butcher a small cheap active speaker and stick that in
the case, though. Might even have room for a pair, one in each side
panel :-)

I use two of those, one in each of the two machines on my desk (XP Pro and
98SE (for legacy games) and KVM switch). I have a scanner, printer. KVM and
an ethernet switch on my desk already and the last thing I needed was two
sets of speakers and the attendant wiring. This alternative makes for a tidy
desk and I'm not all that fussed about the quality of sound in games. That
being said, there are certainly differences between these types of things.
One has a really good sound, a curved front that pivots to point directly at
you if you're sitting off-centre with the left/right speakers facing a
little to the sides which helps with the stereo sound, and a
good-sized/speced main speaker internally, ported externally (2+1 system).
It actually manages to reproduced mid-bass reasonably well. (I make sure it
isn't near HDDs or FDDs as the magnet on the 'bass' speaker is quite large,
I have it above my top optical drive) I can play mp3s using it at a pinch
and it sounds as good as some portable radio/CD players. The other unit just
sucks arse, crackles at anything above a quarter volume and sounds tinny.

The 'good unit' I would highly recommend. It produces a good sound
considering the limitations, runs off a Molex pass-through power lead, has
an external headphones socket, volume control and loudness button. (No
brand-name on it unfortunately). The 'shit' unit is called a 'Soundisk",
runs off a FDD-type power lead. (And, ridiculously, instead of a headphones
socket, it has a aux/in socket). Neither of them is featured on that page
from what I can see.

JME with these devices. I Like the better of the two units I have, it
produces as good sound as a lot of low-end external PC speakers and keeps my
desk tidy. I wish I had more of this model, I'd never use externals again.
(I have a PC hooked into a stereo that is used solely for mp3 play-back).
