The Mass Loading Effects in an Electroacoustic Transducer
摘要
本文主要是分析組合式電聲換能器的一些振動特性。基本上，此換能器是以附加質量負載之軸向振動體為主要結構，各模態的機械阻抗之頻率特性及質量負載後之結點位置變動均做了探討；此外，也討論了換能器等效電路，並藉以幫助分析換能器之性質。本文的數值模擬結果主要係針對不同質量負載或不同面積比值時電聲換能器設計與其振動性質間的關係進行闡述。

An analysis of the vibration characteristics of a composite electroacoustic transducer, which is essentially a longitudinal vibrator with attached masses, is presented. The frequency characteristics of mechanical impedance and the variation of node position, caused by the loaded masses, of each normal mode are studied. The transducer equivalent circuit representation is also discussed. The numerical results in this article are illustrated for some different mass loading with emphasis placed on the relationship between the vibration features and the electroacoustic transducer design.
