近年來全球暖化的問題日益嚴重，各種替能源在科學家的努力之下，接續問世 ，其 中有使用燃燒產生熱能，以熱能轉化成電能的火力發電、以風能帶動機械轉動，放大成 機械能，再轉化成電能的風力發電、也有將太陽能光伏轉換成電能的太陽能發電等。但 鮮少有人以「噪音」環保能源的來源，在人類的生活環境中，存在大大小小的噪音，大 至飛機劃過天空的噪音，小至汽車引擎運轉的聲音，本文嘗試以噪音做為再生能源的來 源，以 振動 機作為載體，以實驗找尋可產生最大噪音能量的 g 值設定，再以此 g 值測試 能產生最大噪音能量的頻率參數 。 實驗 首先利用藍芽無線通訊技術將指令訊號傳入振動機，使其作動產生噪音，再以 電容式麥克風接收噪音訊號 ，並將噪音轉換電壓訊號，分析比較特種狀態下的能量轉換 效率。;The problem of global warming is getting more and more serious. Developing another renewable energy becomes one of the most important subjects that everyone living on the earth is facing. With effort of scientists, we translate winds, fire, solar are tranfomed into useable energy but seldom of them regard NOISE as an energy source. In modern society, noise is all around our daily life. Noise comes from engine of a moving vehicle or a working machine. In this article, we use “vibrating machine” as a noise source, and try to figure out the best condition that can generate the greatest amount of energy. First of all, Computer send commends to vibration machine with Bluetooth wireless connection. In the meantime, collect the noises come from the vibrating machine with a condenser microphone. With the working method of microphone, it converts the sound wave into the voltage signal.
