From what i have been learnt, the magnet is connected to the diaphragm (the material which covers it) of the speaker and as electric current is passed in this causes the magnet to 'Push' and 'Pull' on the diaphragm making this move resulting in sound waves being produced, these sound waves then enter your ear making you hear the noise. So the magnet helps produce the sound you hear from a speaker.

Why there is a vibration in the speaker when a cell phone rings when it is brought near the mic?
Answer: It's called inductance. A lot of speakers use a magnet attached to a cone and place that magnet in a set of wire coils. When power is applied and changes, the magnet moves in relation to the amount of power flowing through the coils. An antenna is a very long coil meant to capture electromagnetic waves and turn them into electricity flowing back and forth in the coils. So when a cell phone (radio wave generator and receiver) produces strong enough waves, any nearby coils will pickup some of the signal and change it to electricity. here the speaker picks up the waves from the radio and moves the speaker based on the signal from the phone. If you move the phone far enough away from the speaker, it will lessen the effect (radio wave strength is related to distance inversely - (power/d^4) versus (0.distance x power).) The stronger the phone signal or the closer it is to the speaker, the higher will be the chance that the magnet will move based on the radio signal and not just the power coming from the audio product.
Does a fan have a magnet?
Not all fans do need a magnet - there are hand fans, punkah walla fans belt driven fans (as in your car) and Stirling engine fans that I can think of that do not need a magnet. It is only electrically driven fans that require a magnet because they work on the principles of electromagnetism.

Which pole of a magnet is attracted to iron?
Any of the two poles will work. It will induce magnetism in the iron.
How to remove magnet from a speaker?
To remove a magnet in a speaker, first detach the grill in the front of the speaker, second unscrew the speaker after that remove the speaker from the cabinet and cut the speaker cone. Lastly, gently discard the magnet from the speaker cone.
How does an electro magnet work in a speaker?
The electromagnet is used to vibrate the diaphragm of the speaker and a given rate (frequency) to produce a given sound.
How can a speaker work with holes in it?
It can work, but it will not sound good. Any deformations of the cone will "color" the sound, which will sound muddy and not clear. Eventually the speaker will die due to the voice coil dragging in the magnet because the speaker isn't moving correctly. If you have a speaker with a hole in it you should replace it.
Why do speaker have magnet?
The magnet is part of the 'motor' of the sub. The coil inside the magnet has alternating current running through it. The coil acts as an electromagnet and pulls itself up or pushes itself down moving the cone of the speaker. The bigger the magnet, the stronger the magnetic field inside the speaker where the coil is.
Would a speaker with a larger magnet always sounds better than a speaker with a smaller magnet?
Definitely not. Sound quality depends on so many different things.
Can touching metal to a speaker magnet ruin it?
No, but placing a video tape on a speaker will ruin the tape
Why does a telephone use a magnet?
There is a magnet in the both the microphone and speaker. They change differences in air-pressure (in the microphone) to electrical pulses, and in the speaker, they cause the cone to vibrate - creating sound.
What parts do the electromagnet electric motor and speaker have in common?
A magnet
Where is a magnet located on a speaker?
At the back of the cone where the wires connect in
How could you show that a loud speaker has a magnet in it?
Figure it out yourself
Zapper won't work on key for opel zafria?
Have you had your key anywhere near a magnet of any description? Even a speaker magnet can knock out these keys. You'll probably need to get your key reset by your dealer. Or your battery may need changing?
How a loudspeaker works?
A loud speaker (like other speakers) produce sound (which is actually vibrations in the air heard by the ear) with a permanent magnet and a temporary magnet in wire form that is wrapped around the permanent magnet. (or a magnet that can be turned on and off by electricity) the speaker translates the sound into a series of electrical currents and then produces the electricity to alter the temporary magnet and making the magnets vibrate and in turn vibrates the air.
