摘要
研究了不同谐振腔接收器表面的声压大小,发现谐振腔内增减凹球面反射面对声压波形有较大影响。分析了声压波形发生变化的原因,认为增加凹球面反射面时,声压波形变化是由于声波在谐振腔上下两表面存在非垂直反射。
The sound pressure on the surface of receiver in different resonator is studied. We find there is a great effect on the sound pressure waveform whether or not there is a concave reflector in the re- sonator. This article analysis the reasons of sound pressure waveform changing, we believe that it is due to the sound non-vertical reflecting on the surface of the resonator causing the sound pressure waveform changing when increasing concave reflector.
