knowing that sound gives off waves, like ripples in water, they travel into the mouth piece there the sound waves are copied by the trasmitter behind the transmitter are carbon grains that when an electric current is traveling makes the grians vibrate and that alters the resistance of the grains as a whole. In this way the sound makes more and less current flow in the circuit in proportion to the sound.
At the other end was a coil of wire within a magnet attached to a diaphragm. The variations in current caused the wie tomove in the magnetic field and so make the diaphragm vibrate in sympathy. Vibrations (as we learnt at the beginning) move air and this makes sound!
