本文将整个扬声器测量作为一个时不变线性系统来处理,通过对扬声器的机、电等效网络的传递函数以及声场近场扩展表达式的谱分析处理,从理论上获得扬声器各物理参数的计算公式.实际测量系统用微计算机来实现.
In this paper, the whole loudspeaker measurement is treated as a time-invariant linear system. The theoretical calculation of the physical parameters of the loudspeaker is theoretically obtained by the spectral analysis of the loudspeaker’s transfer function of the network and the equivalent network and the expansion of the sound field near- Formula. The actual measurement system using a microcomputer to achieve.
