摘　　要：传统的扬声器箱设计,对低频扬声器单元来说,有三要素:fs,Qts,Vas。提出增加考虑一个加速度系数Bl/Mms的要素,这是与低频音质有关的参数。举了10个低频扬声器单元作比较,选出了认为放音优良的扬声器单元。此方法不仅可改善音质而且简化了分频器设计。对设计二分频的Hi-Fi音箱,卡拉OK音箱,专业音箱音质改善应该都有一定的参考意义。There are 3 elements for the woofers of the traditional loudspeaker design： fs, Qts, Vas. This article suggests adding a considerable element called as Acceleration coefficient - Bl/MMS related with low frequency sound quality. There are 10 woofers comparison cited in the article and the woofer with best reproduction performance chosen by author. This method improves not only sound quality but also simplifies crossover design. There are certain considerable values for sound quality improvement of Hi - Fi loudspeaker, KARAOKE loudspeaker and professional loudspeaker design.
