Why are magnets used in speakers?
Magnets are used in speakers because they create a magnetic field that interacts with the electrical current flowing through the speaker's coil, causing the coil to move back and forth. This movement creates sound waves that we hear as music or other audio.
Why don't my rear speakers work?
wiring problem! check wire connection form radio to speaker,if ok, check speaker coil connection, speaker coil may be loosed.
How are electromagnets used in mobile phones?
The speakers in a mobile phone are driven by passing AC current through a coil in thepresenceof a static magnet transducing the current into kinetic energy by the speaker coil diaphragm.
How do speakers produce the bass and treble at the same time?
There are a few types of speakers, but generally, the "voice coil" type speaker is the most common used for sound systems. It consists of a strong and lightweight paper or plastic cone which is attached to a coil. The coil is aligned so that it surrounds a magnet, but the magnet does not touch the coil. When a voltage potential is connected to the voice coil, the coil and therefore the cone moves. By applying voltage at a specific frequency, the voice coil will move in synchronization with the electrical frequency. The voice coil can be moving slowly, as is required by a low frequency sound, and at the same time a high frequency electrical signal can also be injected into the signal. By overlaying multiple electrical frequencies at the same time, the voice coil will move to produce a wide range of simultaneous sounds.
What is the soft material in speakers?
If you mean the cone inside the speaker - they're usually made of cardboard. It's light enough to move when the speaker is in use - yet strong enough to support the speakers coil assembly.
Why does ohm's matter with speakers?
the vibration produced in the coil of a speaker is due to current passing through it hence it obey ohms law
A device that change electricity into motion using magnets?
-A generator or alternator -A Faraday Induction Coil
Will stereo speakers that handle 275 watts handle a home stereo system pushing 105 watts per channel?
yes it will, but if you try to turn it up to loudly you may cause damage to the voice coil of your speakers
Can you use a 450 watt amp on 600 watt speakers?
Yes, if you don't turn it up all the way. Excessive power to speakers will result in distortion and possibly even complete failure of the voice coil and/or cone.
How does a speker work?
A coil of wire is attached to the diaphragm, and then attached directly to the two terminals, which is why speakers actually can be reverse-polarised (wired backwards). In the coil of wire is a neodymium magnet (really strong magnet). When current passes through the coil, it creates an electromagnet, and trys to cling to the magnet, and when current is removed, the coil won't try to cling. This creates the sound.

Will using one coil on a dual coil speaker damage it?
with only one coil hooked up, a dual voice coil speaker will suffer a loss in reference efficiency of about 3dB (only half the coil windings are being energized) as well as a significant shift in its Thiele/Small parameters. This renders any enclosure calculations inaccurate unless you remeasure the speakers parameters with only one coil hooked up. Failure to account for the different parameters of a dual voice coil speaker with only one coil powered can result in very poor performance.
