摘　　要：设计了三款不同结构的压缩式扬声器相位塞。对安装有不同结构相位塞的扬声器进行了电声参数测量和音质评价。结果表明,相位一致型相位塞的有效频率范围能达到200～9 000 Hz,与其他三种结构相比具有有效频率范围宽、频响曲线较平直,谐波失真小,灵敏度高等优点,总体音质明显好于其他三种结构。Three phase - plugs with different structure are designed. Based on the measurements of the loudspeakers with designed phase - plugs, it is found that the frequency range of one of the phase - plugs can reach 200 ~ 9 000 Hz. Compared to the other three kinds of structures, this phase - plug has wider frequency range, flatter frequency response curve, less harmonic distortion, and higher sensitivity. And the general sound quality of this phase - plug is obviously better than the others.
