CH-11,12型及CH-13,14型(下简称CH系列)电容传声器是一种精密的声学测量工具,它的原理基于简单共振。显然,在膜片和后极板间组成的“电容器”中,若膜片的张力以及膜片和后极板间距离在环境条件变动很大的情况下,仍能保持不变或变化极为微小,则可以认为这种传声器的性能是稳定的。因此我们对CH-11,12型及CH-13,14型电容传声器的结构从根本上进行了一种新的考虑——把膜片直接电镀(铸)在传声器的外壳上,使膜片与传声器壳体成为牢固的一个整体,这样做的效果是极为显著的,使用的方
CH-11, 12 and CH-13, 14 type (hereinafter referred to as CH series) condenser microphone is a sophisticated acoustic measurement tool, its principle is based on simple resonance. Obviously, in the “capacitor” between the diaphragm and the rear plate, if the tension of the diaphragm and the distance between the diaphragm and the rear plate can remain unchanged or change very little when the environmental conditions vary greatly , You can think of this microphone performance is stable. Therefore, we fundamentally made a new consideration to the structure of CH-11, 12 and CH-13, 14 type condenser microphones - the membrane is directly plated (cast) on the microphone housing so that the diaphragm and Microphone housing to become a solid as a whole, the effect of this is extremely significant, the use of the party
