蜗牛型汽车喇叭声道性能分析

Analysis for the Sound Channel Performance of the Snail Shell-like Horn

为了探讨蜗牛型汽车喇叭声道的性能分析及改进方法,依据理想流体媒质中的小振幅声波传播理论,利用ANSYS软件对蜗牛型汽车喇叭声道的声学模型进行了声学有限元分析,得到了蜗牛型汽车喇叭声道的声压和频率特性.从能量的角度给出了蜗牛型汽车喇叭声道性能的评价标准,研究了对蜗牛型汽车喇叭声道进行改进的简化分析方法,为蜗牛型汽车喇叭声道的设计和改进提供了依据.

According to the small amplitude acoustic wave propagation in ideal fluid medium theory,the acoustic model of the sound channel of the snail shell-like horn was analysed by using ANSYS to explore the analysis and the improvement of the sound channel of the snail shell-like horn performance.This paper obtains sound pressure and frequency characteristics of the sound channel of the snail shell-like horn.From the energy point of view this paper give the performance evaluation criteria of the sound channel of the snail shell-like horn.The simplified analysis method of the sound channel of the snail shell-like horn is improved.The basis for the design and the improvement of the sound channel of the snail shell-like horn is provided.
