摘要
本研究主要是針對特殊應用現場，設計出一套以半導體零件之聲音儲存元件來製作數位錄放音系統；此儲存元件是利用有專利之多層式儲存快閃記憶體(Multilevel Storage Flash ROM)儲存聲音訊號。設計上避開傳統機械元件，而使用積體電路(IC)作爲聲音儲存元件，故系統先天上具有其機構強韌性，使得所設計的系統特別適用於如超級市場、速食店、及廣告宣傳車等。經實地測試發現此系統可滿足持續播放、高震動惡劣環境、及高運作可靠性之大眾廣播(Public Address)應用場所。

By incorporating a patented Multilevel Storage Flash ROM as the storage device of voice data and a microcontroller for system supervision, a reliable digital recording and playing module was designed in this research to aim at the application in public address system for harsh environment. An in-site test for the module was conducted and shows that this module can continuously operate successfully in a shaking situation, such as supermarket, fast food restaurant, or advertising propagation and so on.
