摘 要: 介绍了离散扬声器阵列和连续扬声器阵列的基本辐射特性。采用sinc函数理论、QR时间延迟、QR相位延迟等方法,使扬声器阵列的辐射更加均匀、声压级更高。在南京大学消声室进行的实验表明,理论计算与实测结果吻合较好。以上技术可应用于平板电视机、扩声系统等领域。 The radiation characteristics of both discrete-element line arrays and continuous line arrays are introduced. The loudspeaker array has more equal pressure field and higher radiating level by SINC setup, QR timing or phase delay. The experiments are carried out in Nanjing University and the experimental results are in accordance with the theoretical prediction. The technology above can be used in the fields of flat-panel TV sets, sound reinforcement system and so on.
