（2） Working principle

The working principle of a head mounted speaker is based on electroacoustic conversion. Taking the common dynamic coil drive unit as an example, when audio current passes through the voice coil, the voice coil will generate a changing magnetic field. The changing magnetic field interacts with the fixed permanent magnet magnetic field, and according to the principle of electromagnetic induction, the voice coil will be subjected to a force and vibrate. Due to the close connection between the voice coil and the diaphragm, the vibration of the voice coil drives the diaphragm to vibrate synchronously, and the vibration of the diaphragm drives the surrounding air to produce density changes, thereby forming sound waves. These sound waves are transmitted to the ears through earmuffs and perceived as sound by our auditory system. In this process, the frequency and amplitude characteristics of the audio signal determine the frequency and amplitude of the voice coil vibration, which in turn determines the characteristics of the diaphragm producing sound waves, achieving the restoration and playback of sound. Although different types of driving units have different working principles, they essentially convert electrical signals into sound signals, but each has its own characteristics in terms of specific conversion methods and performance.
