According to the principle of sound production, there are three main categories: moving coil type, moving iron type and electrostatic type.headphone manufacturer
The sound principle of dynamic headphones
At present, most of the earphone earplugs are moving coil earphones. The principle is similar to that of ordinary speakers. The coil in the permanent magnetic field is connected to the diaphragm. The coil drives the diaphragm to produce sound under the driving of the signal current. The central protrusion of the diaphragm is the main The vocal area, and the compliant edge next to it can provide enough stroke.
The sound principle of moving iron headphones
Inside the moving iron earplugs, the voice coil is wound on a precision connecting rod called a "balanced armature" located in the center of the permanent magnetic field. The structure of the precision connecting rod is conducted to the center point of a miniature diaphragm. This iron piece Vibrate and sound under the action of magnetic force. Moving iron earphones cost more due to a late start and technical reasons.
The sound principle of electrostatic headphones
The diaphragm is in a changing electric field, the diaphragm is extremely thin, accurate to a few microns, and the coil drives the diaphragm to make sound under the drive of the electric field force. Due to the very high manufacturing cost, electrostatic headphones have always been a relatively niche product.
