PostSubject: Speaker rattle   Tue Oct 19, 2010 11:19 pm

What causes speaker rattle? I have a portable that has a 2 inch speaker that rattles like the dickens when you turn it up. I rebuilt the speaker a while back, so it's more than likely something I did, but I really don't remember it being this bad. Any suggestions?

Surround is loose; coil is rubbing; hidden tear; foreign matter touching the cone or coil form; or, the speaker is OK and something else is rattling.

Ok, I do know it is the speaker. Lightly pressing my finger on the cone silences it. I know the cone is glued down well as is the spider and voice coil, but if the voice coil were rubbing on the pole, what would be the better what to repair that?

It would appear that the speaker coil was not properly shimmed when it was repaired.

voice coil not centered properly.

what is happening is when you turn the volume up, the front to rear movement of the voice coil causes the voice coil to rub the magnet on it's travel back and front.

You could simply being overloading the speaker.... a 2" speaker usually isn't going to give you much fidelity - even at it's best - and they usually aren't made with rebuilding in mind either. It shouldn't be too hard to find a decent sub - the thrift stores around here are replete with old computer speakers - usually $5 or less.....

Worth trying to fix the speaker, but if no go, here's one source. I think Mouser has them, too.

I just noticed the rattle isn't really noticeable in its cabinet unless I really crank it up, but it's really distorting at that level. So I guess I'll just be leaving it alone, haha.
