摘　　要：定向扬声器系统是泛指具有高指向辐射特性,能把声波控制在特定区域内,从而实现声频声定向传播的扬声器系统。介绍了三种技术较成熟并已商品化的定向扬声器的结构和技术特性,论述其在博物馆、美术馆等展陈建筑中的适用性及应用实例。所论述的内容对定向扬声器在其它领域的应用也有一定参考价值。Directional loudspeaker system refers to a high directivity radiation characteristic, can make the acoustic control in a specific area, so as to realize the directional propagation of audio sound speaker system. This article discusses the structure and technical characteristics of three kinds of directional loudspeaker technology is mature and has been commercial- ized, and discusses its applicability and application examples in the exhibit buildings such as the museums and art galleries. The content discussed also has a certain reference value to the application of directional speaker in other fields.
