How the loudspeaker works

The working principle of loudhailer turns electric signal into sound signal namely, when the coil in loudhailer is electrifying, its coil can produce magnetic field, below the magnetic field interaction with magnet, coil can vibrate, vibration can give out sound. In simple terms, it is the force on a conductor in a magnetic field.

Composition of moving speaker material

Horn factory is a material assembly enterprise, so the key of development is the choice of raw materials. The quality of raw materials determines the quality of products to a large extent, and directly determines the cost of products.
