The exceptionally strong and steady magnetic field reacts with the alternating field created by the alternating current produced by the audio current flowing in what is known as the voice coil. The Voice Coil is physically attached to the cone that moves the air so you can hear the pressure wave that simulates the current wave-form.

How does a speaker make sound with electric energy?
A loudspeaker contains a metal coil, known as an electromagnet, that creates a magnetic field when an electrical current passes through it. It is the action of the electromagnet that is responsible for converting electrical energy into audible sound.
Where are the electromagnets in a loudspeaker?
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.
What device use magnet and electricity?
Electromagnet
How does a doorbell use an electromagnet?
The electromagnet is only part of the mechinism the whole item is called a solenoid which has a magnetized rod inside the electromagnet when 24 volts is applied the solenoid springs out of the coils of the electromagnet striking the bell. When released the rod returns by use of a spring and strikes another bell. Ding, Dong.
When would you want to use an electromagnet rather than a permanent magnet?
When you need a magnet you can turn on and off an electromagnet is used.
