| 摘 要： | 本文提出了一种用于扬声器故障诊断的小波包图像处理方法，该方法可以得到各类故障扬声器在扫频信号激励下的时频信息，定义出标准扬声器的时频分布特征。通过比较不同故障扬声器的时频图像与标准扬声器的时频图像特征的欧氏距离，可以判断出扬声器的故障类别。

| Abstract: | This paper presents a new approach used for loudspeaker fault detection based on wavelet analysis. Through the sweep-frequency signal, the time-frequency information of all fault conditions including the standard time-frequency distribution images can be defined. Through comparing the Euclid distance between the image of the standard loudspeaker and images of all kinds of fault loud- speakers, we can determine the category of the fault loudspeaker. |
