再论扩音机与喇叭的阻抗匹配

On Impedance Matching between Megaphone and Horn

本文主要论述定阻型输出和定压型输出扩音机与喇叭匹配的互换性及扩音机所接喇叭的总功率在大于或小于扩音机额定输出功率时扩音机与喇叭的匹配方法

This paper is to expound the interchangeability of matching between the constant resistanle output & constant voltage output of megaphone and horn and the method of matching the megaphone with horn on condition that the general power of horn connected with the megaphone is higher or lower than the rated output power of the megaphone.
