摘　　要：多开口联动低音箱发明已多年,由于种种原因本发明并不为电声界所了解。分析已有低音箱,如倒相式音箱,是在封闭箱基础上增设亥姆霍兹共振器,以提高音箱的低音效果。单开口、双开口带通箱是在倒相箱的基础上再增设一个封闭箱或亥姆霍兹共振箱,所以低音放音效果有所提高,但总体的改进不大。三开口联动低音箱是由音盆联动的三个亥姆霍兹共振箱组成,具有电一声转换效率高、声输出功率大、工作频率范围宽等一系列优点,从不同角度定性分析了这些优点。Three openings linkage Woofer has been invented for many years, but not known in the Electric-acoustic field because of some reasons. According to the analysis, the woofer, such as striper reflex, has been invented, which is e- quipped with helmhohz resonator based on the enclosed speakers, improving its bass effect. Single and double olmproving the bass effect of woofer, speaker design should find a new way. Three openings linkage Woofer, it contains three sound basin linkage helmholtz resonator and owns many advantages, such as high voice conversion efficiency, big Acoustic power output, wide operating frequency range. These feature are analyzed from different respects in opening Band-pass loudspeaker increased enclosed speakers or helmholtz resonator based on the Band-pass loudspeaker.
