The acoustic sources comprise an electronic sine wave generator or a loud speaker and a pneumatic diaphragm horn,by varying the frequency generated,sound pressure,air-to-cloth ratio and the filtering medium,the results have been achieved for reverse-air alone and reverse-air/sonic cleaning.
声源分别采用电磁扬声器和气动喇叭。
Based on this analysis,a detailed discussion is presented for the fields of the corrugated horn and the corrugated horn under the balance condition in terms of the Gaussian mode theory,the Gaussian mode parameters for the corrugated horn are also determined.
以此为依据,详细分析了波纹喇叭横向电场表达式以及计入反射面损失的喇叭辐射场,论述了如何用高斯模表示喇叭口面场,并具体列举了平衡混合状态下波纹喇叭口面场特征参数的求解过程,以及喇叭口面场高斯表示方式。
