What is a loudspeaker ? How does it work ?
by

1 Answer

Answer :

Loudspeaker is an electronic device that converts electrical signals into sound. It is commonly used for listening to music , giving lectures and reading in the classroom. When an electrical signal or wave from the amplifier enters the loudspeaker coil, a magnetic field is created by the electrical induction in the coil. The coil vibrates due to the action of the permanent magnet of the loudspeaker and the magnetic field of the coil. The coil is attached to a screen. As a result, the screen also vibrates with the coil and the air in front of it also vibrates. The resulting sound is generated.
