【摘要】 讨论了扬声器单元低频参数（Thiele－Small参数）的快速测量问题，提出了一种新的计算机测量方法，在系统辨识方法基础上利用一种频域上的聚焦搜索算法去除测量过程中不必要的冗余采样。实验表明该方法在测量速度和精度方面均取得令人满意的结果，适合于在线测量。更多还原

【Abstract】 The quick on-line measurement of the low frequency parameters, Thiele-small parameters is discussed. And a new computer-based method is introduced. The key idea is developing a focusable method to reduce the redundancy of sampling in frequency domain, combined with the system identification technology. Experiments have shown that the method performs successfully in both accuracy and testing speed, and it is suitable for on-line test.更多还原
