Moving-iron earphone is a kind of earphone which is conducted to the center of micro-diaphragm through a precise connecting rod, thus generating vibration and making sound. Moving iron headphones can be easily put into the ear canal because the unit is much smaller. This effectively reduces the area of the ear part and can be placed in a deeper ear canal part. The geometric structure of the ear canal is much simpler than that of the auricle, and it belongs to a quasi-circular shape, so the soft silicone sleeve can play a very good sound insulation and sound leakage prevention effect compared with the traditional earplugs.
superiority
The sound insulation effect of moving iron is better than that of moving coil. Due to the large area of moving coil unit, more space and air are needed to participate in vibration when making sound, which can not effectively control the sound leakage phenomenon; The movable iron can effectively reduce the ear area and can be placed in the deep ear canal.
(Almost all moving iron headphones have air holes, while moving iron headphones rarely see air holes, CK9 is an exception. Because the geometric structure of the ear canal is quasi-circular, which is much simpler than the auricle, compared with the traditional earplugs, the soft silicone sleeve can already play a very good role in sound insulation and sound leakage prevention.
