Abstract

Speaker damage consists of sound damage and appearance damage. Most speaker product defects are due to sound damage, so this greatly affects the quality of the speaker. The voice damage that has the largest percentage is the VCT (Voice Coil Touch) type of damage at 47.6% compared to appearance damage which only reaches 1.6%. This research aims to determine the main cause of VCT damage using the FMEA (Failure Mode and Effect Analysis) method, so it can be seen that the main cause is human factors with the type of failure in installing a slanted voice coil with the highest RPN (Risk Priority Numbers) value of 216.  
使用鱼骨图和 FMEA 方法分析扬声器声损的主要原因
扬声器损坏包括声音损坏和外观损坏。大多数扬声器产品缺陷都是由于声音损坏造成的,因此这在很大程度上影响了扬声器的质量。声音损坏中占比例最大的是 VCT(音圈接触)类型的损坏,占 47.6%,而外观损坏仅占 1.6%。本研究旨在使用 FMEA(失效模式和影响分析)方法确定 VCT 损坏的主要原因,因此可以看出,主要原因是人为因素,其中安装倾斜音圈的故障类型的 RPN(风险优先级编号)值最高,为 216。
