Frequency Division Design of Multi-Unit Moving Iron Earphone

Abstract A high-quality earphone with multiple sound-generating units and frequency-dividing circuits, a core of consisting balanced armature units, aided by analog circuits an shell made light-cured resin, is designed. The whole project physical production realized. analysis results the frequency response curve, which are obtained help tester, show that headphones in sensitivity, curve stability, transient response, many other aspects achieved expected sound quality effect.
