What is attached to the coil of moving coil loudspeaker and it causes compression and rarefaction cycles in air? Correct Answer Paper cone

When audio current is passed through the voice coil placed in a magnetic field, a generated force equal to Bli Newton acts on the coil and move it to and fro. The paper cone attached to the coil also moves and causes compression and rarefaction cycles in the air. Thus, audio current is finally converted into sound waves.
