The Difference Between Dynamic Headphones And Moving Iron Headphones

2018-09-06

The principle of the dynamic circle earphone is similar to the ordinary loudspeaker. The coil in the permanent magnetic field is connected with the diaphragm. The coil drives the diaphragm to sound under the driving of the signal current. Dynamic headphones are divided into open, semi-open, and closed headphones by openness. At present, the vast majority of earphone earphones belong to dynamic earphones .

The moving iron earphone is transmitted through a structurally precise connecting rod to the center point of a miniature diaphragm, thereby generating a vibrating and sounding earphone . The moving iron headset can be easily placed in the ear canal because the unit is much smaller. This effectively reduces the area of the ear portion that can be placed deeper into the ear canal. The ear canal geometry is much simpler than the auricle, belonging to a round shape so a soft silicone sleeve can provide good sound insulation and anti-leakage effects compared to traditional earplugs.

The sensitivity of the moving iron is higher than that of the moving coil. The main reason is that the structure of the moving iron unit is almost a closed container structure. A little current can drive it. Here, it should be noted that the relationship between sensitivity and resistance. Due to the higher sensitivity, the moving iron headphones perform better transiently, and they are far better than the dynamic earplugs in dynamic performance, instant detail performance, and sound density.

Dynamic iron headphones have a more stable frequency response curve. There are some audible changes in the frequency response curve of the dynamic headphones during different temperatures, humidity, and use. Kinetic iron shows good stability, making the sound quality more stable and reliable, and not easy to change. The moving iron is smaller and lighter. Moving iron headphones help protect hearing.
