| Summary: | 碩士 === 國立高雄應用科技大學 === 模具系碩士在職專班 === 103 === Enhance the quality of life, consumer demands for quality rising, but what the speaker is no longer just a simple player device, there are more and more notebooks and players, to emphasize the effect of the bass speaker to attract consumers to buy, designers are increasingly using the bass reflex enclosure, improving loudspeakers in the low frequency extension, tube design and change has become a question worth exploring.
There are many types of speaker design, the most common three types are closed box, bass-reflex speakers and a passive radiator-type speakers, this thesis will illustrate the research on how the different irregular shape tubes worked on the bass reflex loudspeaker in the fixed volume, explore the tube length and diameter, shape, effects on impedance curve, frequency response and distortion, these principles and analysis results may provide the design basis for bass reflex speakers in the future.
