Push and pull the cone rapidly, the moving cone moves the air which we hear as sound.
all of that is true but i would like to add some thing. the electricity that go's in to the speaker go's in and through the coil and turns it in to a electo magnet ang move acording to the way the electricity is moving because there is another perminent maget around it
so the cone moves and air moves and vibrates our ear drums so we hear sound
hope this helps

What is a voice coil?
a voice coil is the electromagnet that causes a speaker horn to move in response to the electrical impulses received from the amplifier.
How does a speaker work in a circuit?
They will either pull in or push out depending on the polarity of the DC voltage and remain stationary. This is a bad idea as the DC resistance of the voice coil is much less than the AC impedance of the voice coil and it is possible to overheat and burn out the voice coil due to the much higher current the DC voltage can produce in the voice coil compared to the AC voltage that would drive the voice coil in normal operation.
What type of microphone is most similar to a speaker?
A dynamic microphone is most similar to a speaker. They both consist of a diaphragm, a voice coil and a magnet.
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.
What is the purpose of the coil in a speaker?
The coil in a speaker, often called the voice coil, is used to convert electrical signals into mechanical vibrations (sound). When an electrical current passes through the coil, it interacts with the magnetic field of the speaker, causing the coil to move back and forth rapidly, which in turn creates sound waves.
What is the part of a loudspeaker that vibrates to make sound?
a speaker uses a voice coil a coil copper wire and a magnet and pole to vibrate a cone
How do you wire Voice coil?
Unless you are an electrician, I would not attempt it, you will need a special tool do wrap it around the axle (The post in which the voice coil moves up and down on). Either have a tech do it for you, or replace the speaker.
What is use of megnetic force in speaker?
The magnetic force in a speaker is used to drive the motion of the speaker cone. When an audio signal passes through a coil of wire (voice coil) attached to the speaker cone, it creates a magnetic field that interacts with the permanent magnet in the speaker. This interaction results in the movement of the speaker cone, producing sound waves.
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.
How does the voice coil interacts with the magnet on the very bottom of the speaker?
The magnet is permanent, and the voice coil magnetism alternates with the current, pushing the cone outward against the magnet or pulling it inward towards the magnet as the current changes direction.
What has magnet got to do with musical equipment?
It is the medium by which a voice coil reacts to or is stimulated by. Reacts: As in a speaker the power sent to the coil creates an attraction creating movement of the cone that produces sound. stimulated : As in a microphone the voice coil is vibrated around a magnet which produces electricity that is amplified to be heard.
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.
