摘　　要：介绍了演示用 Sondhauss管的结构与制作过程 ,它具有直观、简单、成本低等突出优点 ,是一种比较理想的热声效应演示器件。通过初步实验 ,文中对热声管发声机制进行了理论分析 ,有助于更好地理解热声效应 。A visual Sondhauss tube for teaching demonstration is introduced in this paper. After some preliminary experiments, the onset and offset mechanism of the Sondhauss tube is analyzed and the requirement of the sound-occurring is obtained, which is good for the beginners to understand the thermoacoustic effect and is helpful for the further research. This Sondhauss tube is simple and visual with low cost, which is an ideally experimental apparatus for thermoacoustic demonstration.
