the ear, the oppressive feeling, accurate and clear sound localization larger,
more professional surveillance area by this kind of structure, this kind of
structure in low frequency sound headphones on dyeing overweight.
Headphones, the main development
up to now the pronunciation of the unit or moving coil pronunciation unit.
Moving coil in-ear headphones are the most common, the most common headphones,
it's drive unit is basically a small moving coil speakers, the permanent
magnetic field in the voice coil of driving and connected to the diaphragm of
the vibration. Moving coil headphones for high efficiency, mostly on the
headset for the output driver and reliable and durable.
Moving coil headset technology in
development so DuoNian, have very mature after, but the voice in the ascension
also met bottleneck. In addition to electrostatic headset besides, moving coil
pronunciation unit also has a lot of derivative technology, which now using the
most extensive is moving iron pronunciation unit.
Pronunciation unit is to use
dynamic iron the electromagnet produces alternating magnetic field, vibration
part is a metal suspended in the electromagnet ahead, signal after the
electromagnet will make electromagnet magnetic field changes, to make the iron
vibration voice. The advantage is long service life, high efficiency. Defect Mp3 Headphones is distortion,
narrow frequency response. Often used in the early telephone handle. This
technology now, because it is mainly used for earplugs move iron pronunciation
unit in relative moving coil pronunciation unit to small a lot, a lot of
high-grade earplugs in two or even three integrated a move iron pronunciation
unit, each frequency band sound excellent performance.
Now the world first headset is
the SenHaiSaiEr Orpheus headphones, earphones and not using this kind of moving
