wondering if any one knows were u can get motherboard speakers for the beep sounds other then those crappy piezo ones that came with later cases. i looked on ebay there is a few on there but not many and sellers want stupid money to ship to canada for something so small
Those crappy piezo ones don't introduce magnetic fields inside your rig, like the older pc speakers do. The first thing I do when I come across an old PC is to dump the old magnetic pc speaker and replace it with small piezo one.
You know a hard drive magnet can pick up a full PC system unit right? If magnetic fields corrupted computers so bad, they'd have never worked with a hard drive installed.

don't plan on using any hard drives in the system anyway going to probably do an ssd. plus i mean i seen cases were they mounted the speakers right to the HD cage without problem and hard drives already have magnets in them. it may cause an issue with a floppy disc but i doubt it the magnets on a tiny speaker are probably to weak to even do that.
I found a 4 inch PC speaker on ebay for like 10 bucks. Big old honker that sounds great for my 80s DOS games, IMO. If you search "internal PC speaker" or "pc speaker" or like terms you can find them.
I bought this one.

And then I mounted it to the top mesh on my case (the radiator mounts) using long screws and washers.

Yeah a single magnet sure can. But in HDD there is a "magnet assembly" which is a "closed" system of two magnets facing each other, so magnetic field doesn't "escape" that system. That's why HDD plates magnetic coating is not affected by those magnets. The PC speaker introduces a "free" so to say magnetic field in the system. But yeah, only HDD and floppies are concerned.
I've never heard of a speaker magnet messing up hard drives or floppies, even in those AT cases where the speaker is mounted on the underside of the drive cage. You need a much stronger magnet to cause problems.
I agree that for old PC Speaker-only games these big speakers sound way better than a wimpy piezo, so for me they're a must in those scenarios. A piezo is OK if you just use the speaker for diagnosing boot issues and that kind of stuff.
Well anyway, ignoring paranoia of magnetism, all you need is any smallish 8 ohm speaker wired to a 4 pin wide, middle two pins absent header plug for XT through pentium, maybe 2 pin for MMX thru P4, check your board. You can find these in many old radios, toys etc.

Lol. Some of my old systems have lasted over 30years without any effect from the speakers at t all.....😉 Some folk just worry far too much.

Apart from my third eye crt television never had on effect at all as well...😉

If was bad you wouldn't use crt monitors which will have more effect than a piddly pc speaker.

Well, let's never underestimate the power of magnetic fields.
They aren't as good understood yet as pure electric ones.
However, what I'm more concerned of than a speaker's permanent magnet are chassis fans.
Fans generate both types and they move.
So they could cause RFI noise inside the case and among the +12v power rail,
which is the primary one in a PC (aside from - 12v and +5v in vintage PCs).

This thread is laughably absurd
@Caluser2000 No need for a tin foil hat. In fact, it doesn't even protect from magnetic fields, just the electric ones. 😀
If you don't believe in the power of magnetism, please have a look at the wonders of magnetic loop antennas.
People still debate how dangerous they are (when used for transmit): https://forums.qrz.com/index.php?threads/safe … c-loops.741577/
EM fields as generated by chassis fans are very weak by comparison, of course.
Still, the principle is still valid (both use coils, too) - they could cause more trouble than the speaker, afaik.
Btw, the CRT inside a traditional monitor is working like a little particle accelerator.
Any particles of dust and dirt on its screen side get literally smashed into the user's face.
So better keep it clean and keep the floppies at distance. 😉
Edit: I forgot. Stepper motors with their big magnets do function different than conventional motors (cause little RFI).
The principle is very interesting and worth a read.

Good night folks and have nice day! ^^
