Question

Explain why the cone of a loudspeaker vibrates when alternating current passes through it's coil?​

Answer 1

Explanation:

Alternating current supplied to the loudspeaker creates sound waves in the following way: A current in the coil creates a magnetic field around it. ... Repeatedly alternating the current direction makes the cone vibrate in and out. The cone vibrations cause pressure variations in the air, which are sound waves.
