摘要

本研究利用萃智理論及其工具進行分析與解題手法應用於LCD TV揚聲器的產品失效問題分析與解決。其問題包含最低共振頻點（Lowest Resonance Frequency; fo）高、音圈撞擊T鐵產生的異音等，藉由此系統化的分析流程找出確切的問題，利用萃智工具找出問題解答，fo不良部分產生48個概念解，異音不良部分產生49個概念解，輔以普氏矩陣（Pugh Matrix）選擇並整合得到最適概念解，最後驗證最適概念解。fo高之概念解部分彈波加入軟化劑，與音圈撞擊T鐵所產生異音的概念解-T鐵高於華司面，使磁鐵磁力線做不均勻的分佈，防止音圈撞擊T鐵，結合兩者的概念解，使的fo能降低，又能防止防止音圈撞擊T鐵所產生的異音。音圈撞擊T鐵產生的異音概念解部分以音圈長度不變，音圈雙層變四層之概念解可以解決問題。針對上述兩個問題皆可透過TRIZ工具找出解答。

In this study, TRIZ theory and tools for analysis and problem-solving techniques applied to LCD TV speaker of product failure analysis and problem solving. Its problems include low resonance frequency (Lowest Resonance Frequency; fo) high, hit T-Yoke produced noise, etc., by this systematic analysis process to identify the exact problem, use the TRIZ tool to identify problems, for fo problem, produce 48 concept solution, for noise, produce 49 concept solution, supplemented by Platts matrix (Pugh Matrix) to select and integrate to get the optimal solution concept, the optimal solution of the final concept validation. Part of the solution concept fo high elastic wave join softeners, iron and voice coil hit T abnormal noise generated by the concept of the solution above the washer -T iron surface, so that the magnets do uneven distribution of magnetic field lines, to prevent the coil hit T iron, the concept solution combines the two, so that's fo can reduce, but also to prevent the voice coil to prevent abnormal noise impacts generated by T iron. Different sound solution concept hit part of the voice coil to coil T iron produced the same length, the double voice coil four variants of the concept of solution can solve the problem. In response to these two problems can be accessed via TRIZ tools to find answers.
