摘　　要：介绍了国外近年来扬声器线阵列的设计原理,分析了理想声源和实际扬声器的差别,数字信号处理技术的作用及计算机技术的运用等要点。强调了转换距离,四分之一功率角,声源间隔等要素在线阵列设计中的重要性,得出结论,线阵列具体产品和理论模型的差别客观存在。现场情况千变万化,应用重点的差异客观存在,存在产品多样性的可能。The design principles of loudspeaker arrays abroad are described in recent years. The differences between ideal sound sources and real loudspeakers, DSP and computer applications are analyzed. The transition distance, quarter-power angle, space of sound sources are important in loudspeakers design. The differences between ideal line arrays and real line products exist objectively. Compromises and diversity in the design are the problems what designers need consider for the application.
