The diaphragm is what vibrates and transfers the sound to the air.
The voice coil is the "motor" behind the diaphragm. (current through the coil produces the emf that opposes the magnetic field of the driver magnet assembly and causes the coil to move in or out)
Either or both can be damaged by being overdriven. Only the magnet is durable.
