| Summary: | 碩士 === 東南科技大學 === 機械工程研究所 === 105 === Speakers and speakers combine the fields of aesthetics, electricity, mechanics and acoustics, and different loudspeaker systems have different effects on the rendering of music. However, the most important feature of physics is that it converts electric energy into sound energy.
The design and development of a bass reflex type loudspeaker system in this research, using the 6.5 inch full range speaker speaker unit plate respectively using 18mm southern pine wood and multi-layer plywood made two groups of bass reflex enclosure, and the front baffle is arranged below the speaker in circular bass reflex holes, and to the reflection hole arranged round acoustic duct.
In this study, LEAP simulation software was used to investigate the effects of speaker size, number of sound absorbent cotton and circular sound duct length on bass response in bass reflex speakers. The loudspeaker system is designed and developed according to the simulation results, and the effect of music on loudspeaker system test is good.
