碩士 === 國立中正大學 === 機電光工程研究所 === 101 === For solving the globe warming problem, the action of creating renewable energy by wildly building the solar and wind power plants has been undoubtedly to become two major developments. Unfortunately, the above two major efforts accordingly rely on a huge budget as well as a suitable working place to fully display their function efficiency. On the other hand, a newly developed technique by sound power generator to create renewable energy has caused much attraction since its friendly adoption, nevertheless the surrounding environment is lack of sunlight and wind. At first this paper is discussed about vibrating energy and compared with other types of energy, and then began to design sound generator device, we use the electromagnetic induction to achieve the purpose of catching sound energy , and then analyzed the relationship between induction coil diameter and output power, and the position of the induction coil placed on, the number of induction coil, last we simulated a sound source to identify the frequency of the sound generating device (5Hz ~ 100Hz ) in the performance, and improved with this device. Through our experimental results we found that when the number is one induction coil, wire diameter is 0.6mm, location in the center of the film and frequency at 40Hz, the volume is at 110dB, the largest output voltage is 49.5mV, the output current is 4.5mA, and the output power is 222.75 μW.
