Based on computer simulation technology, the loudspeaker system is simulated and analyzed in time domain with MATLAB and EWB software. A series of step function responce and impedance curve of loudspeaker are introduced. 以计算机仿真技术为基础,通过MATLAB和EWB软件进行系统模拟分析仿真,得到扬声器系统的阶跃响应、阻抗曲线等特性。
Make the loudspeaker sample with this kind of cloth side cone loudness curve and impedance curve be similar to that of foam side cone loudspeaker which offered by the Philips Inc. 用这种布边音盆制得扬声器样品,其频响曲线和阻抗曲线与Philips公司提供的泡沫边扬声器的频响曲线和阻抗曲线类似。
This paper proceeds from equivalent analogy circuit of the loudspeaker system, derives formulas of its characteristic impedance Z ( j ω) and draws curve of it. 从扬声器系统的等效类比线路出发,得出了阻抗特性Z(jω)的表达形式及其曲线。
