一种脉冲控制的可变频率脉冲声发生器设计

A Method to Design a Pulse-controlled and Variable-frequency Generator of Sound Impulse

实际测量中经常用到脉冲声,脉冲声源的机动性因此变得非常重要。研究了一种频率可控的脉冲声生成技术,介绍了脉冲声的设计方案和脉冲声的产生机理,设计了一种能够产生不同频率和不同发声时间的脉冲声信号的脉冲声声源装置。

The impulsive sound is often used in actual measurement, the mobility of the impulsive sound source is very important. A generating techology of impulsive sound with controlled frequency is discussed, the designing proposal and the generating principle of the impulsive sound are introduced. The impulsive sound source device of impulsive sound is designed, which can produce the impulsive sound signal with different frequencies and different phonating time.
