Which speakers are better unshielded or shielded?
the shielded speaker is better
How can speaker performance be improved?
Use speaker wire that is shielded better and has a lower resitance.
How do you know if a speaker is magnetically shielded?
The only way I can think of is by detecting the presence of a magnetic field around it. Of course, you can simply put it near your (CRT!) monitor and watch if the colors get twisted around, but that's what you try to avoid, right? Still, if it was sold as a computer speaker, it probably is. If you've got an old black-and-white TV set somewhere, you can swing the speaker around it without fear, it can't harm it, and if the picture doesn't distort, it's shielded. If you've got an LCD monitor, it doesn't matter, they are not affected. Or you can just open the speaker enclosure and see if the speaker magnet feels significantly magnetic to a piece of iron. Shielded speakers actually have another magnet stuck to their back, that cancels out almost completely the actual speaker magnet's field. The two magnets are oriented such that they are actually repelling each other like mad, otherwise they would add up their fields not cancel them. So there you go...
What is the literary definition of speaker?
Narrator
Does TV have magnets?
No. No house hold or normal entertainment speaker magnets will effect an LCD TV. Think about it, the speakers in the TV its self have magnets. Do not worry about placing speakers near you LCD TV. If you think like this then you don't go top the depth of the truth. The actual thing is the lcd's speaker's are magnetically shielded. So they won't affect it.
Static noise on surround sounds sub woofer?
Static noise on speakers usually means the speaker wire is not shielded properly. Replacing the wire with high quality speaker wire will likely solve the issue.
Is holding a magnet up to your computer screen bad?
Yes...thats why your speakers are magnetically shielded......anyway it's clearly not going to be good is it? You're not going to win anything or make any money or indeed achieve anything by doing it, unless you get enjoyment out of it.
What is the definition of wire called a shielded pair?
When you get wire that is a shielded pair, you get two individual conductors that are each individually insulated from each other, and the pair is twisted and wrapped with a thin layer of foil to provide electromagnetic shielding to the pair. Occationally you'll see the pair is surrounded with a braided shield, but not commonly. That's your shielded pair.
What is the difference between a shielded and an unshielded speaker cable?
The difference between a Microphone (shielded) cable and a normal speaker cable is that, When we use a microphone we use a balanced or shielded cable (with the three pins, XLR or cannon), not a normal two wire speaker cable. We use this because the single coming from the microphone is at mic level, below LINE level (less than 1 volt). The shield on the mic cable is connected into the mixer or amp. The shield wire (RF, Radio frequency interference) single its 'waves' are then flipped (reverse phase) to cancel the interference out, any excess interference is then taken to the earth wire. With out a shielded cable you would hear annoying interference eg. The typical phone beep (please turn phone off). Speaker cable does not need a shield because the signal coming into the speaker is above MIC level and RF interference can't get in (it isn't loud enough) so there is no RF interference and no need for a shield. Hope that has been a help!
What do magnetically soft substances do?
magnetically soft substances gain there magnetism easily but also lose it easily
How do you convert magnetic energy into kinetic energy?
This can be done with magnetically propelled trains, they can also be made to levitate magnetically.
What is the difference between speaker cables and instrument cables?
Speaker cables may not necessarily need shielding if legnths are kept short. Istrument cables are shielded and kept to short stadardized lengths to prevent the introduction of noise which would affect the accuracy of the test reading.
