摘要
分析了在开口箱中倒相管的作用,并且介绍了开口箱品质因数QTSB的调整。与调整开口箱的阻抗曲线的谷fM(fB)使它达到能与设计值fB(fBO)的常规方法相比较,称此方法为"品质因数调整法"。通过控制开口箱的品质因数,从而使音箱获得良好的低频特性。
The phase-inverted tube in the vented-box and the adjustment of quality factor QTSB are introduced. Compared with the conventional method, in which the valley of the impedance curve fM (fB) is adjusted to the designed value fB (fBO),the proposed method is called "quality factor adjustment method". The quality factor is controlled to make an excellent low frequency characteristic.
