Explanation:

In order to translate an electrical signal into an audible sound, speakers contain an electromagnet: a metal coil which creates a magnetic field when an electric current flows through it. ... This means that it is in turn attracted to and repelled from the permanent magnet, vibrating back and forth.

Answer:

The basic principle of sound is the vibration of molecules. This is the reason we cannot hear sound in space (vacuum). When you speak, the sound waves agitate the air molecules near your mouth, these molecule in turn vibrate their neighbouring molecules. This chain reaction continues all sound energy is spent in the vibration of molecules. So if you speak louder (i.e. with larger energy), it is audible for more distance.

Headphones consist of two magnets. Similar to electric charge, magnets also repel or attract each other depending on their polarity
