Would the size of a magnet affect the sound quality through a speaker?

Yes a greater magnetic field would alter the sound produced and (if other factors remained the same) the effect required by the amplifier to reach a given sound pressure level.

How does a loudspeaker use a electromagnet?
IN a loud speaker there are two magnets. one permanent magnet that always has its northpole pointing in the same direction , and one electro magnet that can change its magnetic field in direction and magnitude. IF both northpoles point into the same direciton ,the speaker cone is pushed out, if both point in opposite directions the speaker cone is pulled in. The direction and magnitude can be controlled by the current passing through the electro magnet.
Will a magnet affect a credit card?
yes but it depends on the type of magnet and how strong it is
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.
Why is there a small hole at the bottom center of a speaker magnet?
This hole is most likely to allow air to escape from the back of the speaker, allowing the speaker cone to vibrate more freely.
Why does a speaker need an electromagnet not a permanent magnet?
One of the main kinds of speakers needs both. Sound in the form of varying electricity is fed through part of the speaker known as the 'voice coil' which is actually just an electromagnet. Since the electricity in it is varying the magnetism produced by this coil varies too. The voice coil is placed close to a permanent magnet and the voice coil is permitted to move back and forth in response to the electricity going through it. A big cone is fastened to the voice coil to transmit the movements of the voice coil to the air more efficiently. Thus overall the permanent magnet and the electromagnet work together to produce the sound waves that we hear from a speaker. For a more detailed explanation go to the How Stuff Works web site and search for speaker.
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.
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.
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.
Do magnets work through paper?
Yes, but the thickness of the paper will affect the holding capability of the magnet.
What kind of magnets are in speakers?
There is usually a large circular magnet in speakers. When an electricial current is put through the speaker cone at a certain frequency it makes the magnetic fields around the magnet change. The cone is connected to the diaphragm of the speaker which vibrates, pushing the air, creating sound waves.

Can touching metal to a speaker magnet ruin it?
No, but placing a video tape on a speaker will ruin the tape
Does magnet size affect the strength of a magnet?
Yes it does!
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 is the difference between coaxial and 2-way speakers for car?
Coaxil speakers share one coil, magnet and drive piston whereas a 2-way speaker has 2 individual coils for the speaker and tweeter which make for generally better quality.
How does a magnet work in a speaker?
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.
What is the use of magnet in speakers?
Principle is electromagmnetism. When a conductor cuts magnetic field electricity is induced in the conductor (Fixed magnet). When a magnet is moved near a conductor electricity is generated in the conductor (Fixed conductor). In speakers magnet is fixed and the conductor (in the form of a coil is fixed to the back of the diaphragm) is allowed to move freely. As the coil is fixed to the diaphragm the movements of the coil is reciprocated by the movements of the diaphragm. Our voice induces varying current in the microphone and the same varying current is passed through the coil of the speaker hence it moves in the static magnetic field.
