A Study on the improvement of the audio acoustic characteristics by the condition of the duct design

덕트의 설계 조건에 따른 오디오 음향환경 개선에 관한 연구

In this paper we conducted research about the speaker's acoustic characteristics by the condition of the duct. It is expanding the bass ton play frequency as interfere two frequencies each other which originate from the speaker's back and front side using duct as attach the duct of round shaped or square at the encloser. This is not making of bass ton range using interference,. The structure of the duct which using the experiment is round shape. And we confirmed that can expand the limit of bass ton play as compare the actual experimental wave that after simulation of play frequency range as lenth change
