Dynamic earphone
Dynamic earphones are divided into open, semi open and closed earphones according to the degree of openness. At present, most earplugs belong to dynamic earphones,
The principle is similar to that of ordinary speakers. The coil in the permanent magnetic field is connected with the diaphragm, and the coil drives the diaphragm to make sound under the drive of signal current.
Moving iron earphone
Moving iron earphone is a kind of earphone that transmits to the center point of a micro diaphragm through a precision connecting rod to produce vibration and sound.
Moving iron earphones can be easily put into the ear canal because the unit is much smaller. This approach effectively reduces the area of the ear
It can be put into the deeper part of the ear canal. The geometric structure of the ear canal is much simpler than that of the auricle. It belongs to a kind of circle, so it is a soft silicone sleeve
Compared with the traditional earplugs, they have good sound insulation and leak proof effects.
Coil iron earphone
Dynamic horn + moving iron horn combined earphone,
Coil iron earphone is a combination of the strengths of the two speakers. Through the frequency divider, the moving coil is used for low and medium tones, and the moving iron is responsible for medium and high tones
So as to achieve excellent separation, sense of hierarchy, analytical power and more delicate sound.
