电火花发出的声脉冲具有脉冲宽度小、无方向性和声级高等特点,因此它是研究厅堂音质的脉冲响应,混响时间和模型试验的理想声源.当声级足够高而稳定时,还可作为隔声测量和高声强冲击波换能器近场校正之用.这里我们采用了高电压小电容放电的方式.在控制电路方面设有自动、手动和遥控装置,便于使用.本脉冲发声器电路简单,性能稳定,装置紧凑,使用方便. 本文主要介绍火花发声器的原理,电路设计的特点,声源的声学特性以及应用等.
Because of its small pulse width, non-directional and high sound level, the spark pulse emitted by EDM is an ideal sound source for studying the impulse response, reverberation time and model test of the hall sound quality. When the sound level is high enough and stable, But also as a sound insulation measurement and high-intensity strong shock wave transducer near-field correction purposes here we use a small high-voltage capacitor discharge mode in the control circuit with automatic, manual and remote control device for ease of use The pulse Sounder circuit is simple, stable performance, compact device, easy to use.This paper mainly introduces the principle of spark sounder, the characteristics of circuit design, the acoustic characteristics of acoustic sources and applications.
