在一定的条件下,热可以自发地产生声音,这就是热致声现象.热声现象的发现已有200百多年的历史,但是,基于热声效应的高能量密度热声器件的研究和开发则是最近十几年的事.热声器件使用惰性气体、没有机械运动部件,因此,具有完全环保和高度可靠等突出优点.随着研究工作的深入,热声
Under certain conditions, heat can spontaneously generate sound, which is the phenomenon of thermo-acoustic phenomena. The discovery of thermoacoustic phenomena has a history of more than 200 years. However, the research on high-energy-density thermoacoustic devices based on the thermoacoustic effect and Development is the last ten years of things.Physical sound devices using inert gas, there is no mechanical movement of components, therefore, has a completely environmentally friendly and highly reliable, and other prominent advantages.With the deepening of research, thermal sound
