碩士 === 東南科技大學 === 機械工程研究所 === 106 === Speakers and speakers are a combination of aesthetics, electrical, mechanical and acoustics of the mixed field, different speaker system for the performance of the music is different. However, from the physical point of view, its main feature is the conversion of electrical energy into sound energy. This study was designed to develop a bass reflex speaker system using a full range Fostex FE166En 6.5-inch speaker unit 18mm South pine board and multi-layer plywood made of speakers composed of loudspeaker system. Under the speaker set the circular bass reflex hole, and in the reflection hole to add a circular guide tube. In this study, LEAP simulation software to explore the speaker size, the number of sound-absorbing cotton and circular guide tube length on the bass reflex speaker bass frequency response. According to the simulation results designed to complete the development of the speaker system, the actual music to the speaker system test with good results.
