摘　　要：二十世纪六七十年代,根据福建海防前线对台宣传的需要,中国科学院声学研究所协同参与"700工程"任务的各单位,在多次试验基础上提出了有线广播站新扩建总体设计方案,研制出了当时世界上声功率最大的可用于音频广播的气动扬声器。大功率远程有线广播系统的研制不仅满足了当时对台宣传的军事需要,同时也对我国电声学、大气声学、语言声学等声学分支学科的研究工作与人才培养发挥了积极的推动作用。The sixties and seventies of the 20 th century,according to the publicity needs of the Fujian Coastal Defense Front toward Taiwan,and based on many experiments and in cooperation with"Project 700"-related institutes,the Institute of Acoustics,Chinese Academy of Sciences proposed the overall design of the cable stations expansion,and developed the pneumatic loudspeaker with the largest sound power in the world for audio broadcasting.The development of high-power remote cable broadcasting system not only met the military needs of the publicity toward Taiwan at that time,but also played a positive role in promoting the research work of the branches of acoustics such as electroacoustics,atmospheric acoustics and speech acoustics,as well as talent cultivation in China.
