The principle is to use the current flow through the conducting coil to generate a magnetic field, magnetic field and the interaction of permanent magnetic materials, driving the thin film vibration to produce sound.

The voice coil inside the moving iron earphone is wound on a piece of iron called balance armature in the center of permanent magnetic field. This armature is actually a moving iron unit, and this armature is driven to sound by magnetic force. It USES an electromagnet to generate an alternating magnetic field.
