北京中佳华音响中心推出的6401系列书房音箱,在高音单元的制作中采用了国际先进的磁冷却技术,使高音单元的性能得到很大提高。 磁冷却主要是在高音单元的音圈周围加入了“磁液”,这是一种近乎液态的磁性材料,系由铁磁性或亚铁磁性材料球磨成直径100埃的超微粉粒,表面包覆一层能降低其张力的活化剂,使铁磁
The 6401 series of study speakers introduced by Beijing Jiahua Audio Center adopts the international advanced magnetic cooling technology in the production of the tweeter, so that the performance of the treble unit is greatly improved. Magnetic cooling is mainly in the tweeter around the voice coil by adding “magnetic fluid”, which is a near-liquid magnetic material, ferromagnetic or ferrous magnetic material by ball milling into ultra-fine particles of 100 A diameter, the surface coating A layer of activator that reduces its tension causes ferromagnetism
