I think you've answered your own question.
It might make an electromagnet by doing this.
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.
When a coil becomes a magnet, the magnetic field it produces interacts with the magnetic field of the cone. This interaction can cause the cone to vibrate or move, creating sound waves and producing sound in a speaker system.
Electromagnets are not used in commercially available loudspeakers due to unlinear sound reproduction, noise induced by the electromagnet current and cost. A permanent magnet with a moving coil in the magnet gap is far superior to an electromagnet considering these three parameters.
When the speaker cone moves forward, it compresses the air in front of it, creating a high-pressure region. As the cone moves backwards, it rarefies the air, creating a low-pressure region. This rapid oscillation of high and low-pressure regions propagates through the air as sound waves.
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.

the reason a speaker blows when you turn it up too loud is because the coil gets hotter and hotter when the cone moves a lot. it will eventually get so hot that the coil will start to smoke then crackle and then stop working.
The permanent magnets in a stereo speaker are used to create a magnetic field that interacts with the electrical current flowing through the voice coil attached to the speaker cone. This interaction causes the voice coil to move back and forth, pushing and pulling the cone to produce sound waves. The permanent magnet near the cone provides a stationary magnetic field, while the magnet on the cone moves with it to drive the sound production.

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
Electrical signals from the radio's circuitry energizes the voice coil of the speaker, which moves the cone of the speaker, that in turn disturbs air particles in its proximity, creating sound.
A: A speaker has a magnet and the wire is suspended in a zone by a cone whereby +/- current will make the coil move up or down moving the coil and moving the cone causing air displacement as waves of pressure that our ears can detect as sounds in our brains.
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.
When a coil becomes a magnet, the magnetic field it produces interacts with the magnetic field of the cone. This interaction can cause the cone to vibrate or move, creating sound waves and producing sound in a speaker system.
