How Do Speakers Work?

Speakers convert electrical energy into mechanical energy. This mechanical energy then further compresses air, which results in the production of sound energy. The speaker driver is responsible for converting energy from one form to another. This driver acts as a transducer that converts electrical energy from the device that you use to play a sound into actual sound pressure waves that your ears can detect. 

Do you still need clarification as to how do speakers work scientifically? Here’s an in-depth explanation. 

The amplifier sends the signal to the terminals present on the back of the speaker. Then, this current is passed on to the cylindrical coil that is made with wire. This coil is suspended in between the poles of permanent magnets. The coil moves back and forth as the current is passed through, and the one end of the centre of the speaker cone that is connected to the coil also moves with it. This creates air pressure movements that produce sound.
