电子模拟声系系统的设计

The design of the Sonic tool to simulate acoustic system

针对目前检测声波电子线路时,存在精度低,误差大,耗时耗力等问题,设计了一种基于电子技术的模拟声系系统,该系统由主控制电路、发射脉冲接收电路、信号发生及整形电路、时差显示及调节电路等组成。系统在电子线路声波发射脉冲的作用下产生四路波列信号,波列信号的时差及首波幅度等参数均可实时显示,并可通过按键实现精确调整。通过实验测试及实际应用表明,该系统的各项指标达到了设计要求,体积小巧,操作简便,精度高,误差小,适合现场及各种测试场合的使用。

Sonic tool maintenace and testing of electronic circut need the acoustic wave signal that the sound system probes supply,but as the abnormal signal caused by the degrees of coupling in the sink and in cased well of the sound system ,so the testing work will encount some influence.To solve this problem,this artile designs a set of electonic simulation sound system which can link sound electronic circut directly ,this system can make four wave signals under the action of the pulse producing by the sound,the jet lag of the wave signal and the first wave parameters such as amplitude can real-time display,and which can make precise adjustment by the keys.The experiment test and practical application show that each metric of the simulation sound system meets the design requirements.The system is small size and simple operation ,so it is very suitable for the scene and the use of various.
