一种高声强声源的研制

Development of An High Intensity Acoustic Source

本文叙述了一种大功率、宽频带的高声强声源,其额定输出功率为6000声瓦。该声源不但能满足宇航和航空高声强环境试验的需要,还可作远程音乐和语言广播。文中介绍了DQY-6000S电动气流扬声器的工作原理,设计理论着重分析了振动系统的特性,报导了调试测定的方法和性能数据。

This paper describes an acoustic generator with high power and wide bandwidth.The electrophneumatic Loudspeaker has normal power output up to 6000 acoustic watts. It can meet the needs for high intensity sound environmental test in astronautic and aeronautic engineering, as well as transmit music and Language to far distance.This paper briefly introduces the operation principle of DQY-6000S Electrophneumatic Loudspeaker and elementary design theory, analyses characteristics of vibration system amphatically, and finally gives the method and data about adjusting (?)d measuring.
