In this paper, the equivalent circuit method is used in analysing the performance of the vibrating system of an electropneumatic loudspeaker, and results are given for the input impedance and displacement amplitude as functions of frequency, and applied to typical designs of this kind of loudspeakers, illustrating the value of equivalent circuit analysis in guiding its practical design. The electrical driving power required for the vibrating system is proportional to the fourth power of the mechanical resonance frequency, which is the upper limit of the frequency range of the electro-pneumatic loudspeaker. Thus the high frequency performance is poor. The optimum condition is found for a flat frequency response below the mechanical resonance frequency. Experiments show that under the optimum condition the high frequency response improves slightly with increase of the magnetic induction in the gap of the magnetic structure. Experimental results agree well with theory, and sound pressure levels up to 181 or 184.8 dB re 2 X 10-5 N/m2 under different conditions were obtained in the horn thoat of the loudspeaker.

本文用等效电路方法分析了电动气流扬声器振动系统的特性,求得了气流扬声器的输入阻抗和位移振幅的频率特性,并把结果用于典型扬声器,说明用等效电路分析指导气流扬声器设计的作用。气流扬声器振动系统所需的电功率与其机械共振频率的四次方成正比,其声辐射主要限于共振频率以下,因而高频特性较差。求得了在共振频率以下,频率响应平直的最佳条件,实验表明,在最佳条件下,气流扬声器的高频特性随着磁隙中的磁感应强度的增加仍稍有提高。实验结果符合理论分析,测得气流扬声器喇叭喉部的声压级在不同情况下达181分贝或184.8分贝(零分贝等于2×10~(-5)牛顿/米~2)。
