众所周知,传统的音箱均采用功率分频来分配高、中、低频成分,然后分别推动相应的高、中、低频扬声器,从而合成全频带的声音。然而,功率分频器的LC滤波器,存在分频电感,功放的阻尼系数被大大劣化,严重影响低频的重放质量。同时,电感电容带来的相移和线性及非线 As we all know, the traditional speakers are used to divide the power distribution of high, medium and low frequency components, and then respectively promote the appropriate high, medium and low-frequency speakers, which synthesized the whole band of sound. However, the power divider LC filter, the presence of frequency-division inductance, amplifier damping coefficient is greatly deteriorated, seriously affecting the playback quality of low-frequency. At the same time, the inductances bring the phase shift and linearity and non-linearity
