    • PURPOSE: To obtain a microphone which is highly sensitive and has an excellent frequency characteristic even at a high temperature by constituting a tension ring and electrode with metal having a low line expansion ratio and then constituting other composition parts with metal with a line expansion ratio larger than that of the former metal.
      CONSTITUTION: All composition parts expand as temperature rises. A tension ring 10 pushes up a vibrating film 5 upward the upper surface of a vibrating film 1st fixed ring 4 to give a certain tension to the vibrating film 5. Here, since the metal with a line expantion ratio smaller than that of the vibrating film 1st fixed ring 4 is used, their expansions will not be similar, and the extension in the cylindrical direction of the tension ring 10 due to the rise in temperature is smaller that of the vibrating film 1st fixed ring 4. Thus the tensile force given to the vibrating film 5 by the tension ring 10 is smaller compared with at room temperature, and the extension of the vibrating film due to cleep together with the rise in temperature is also smaller.

    • 目的:为了获得高灵敏度的麦克风,即使在高温下,通过构成具有低线膨胀率的金属的张力环和电极,然后用线膨胀率较大的金属构成其它组成部分,也可以获得极好的频率特性 比以前的金属。 构成:随着温度的升高,所有组成部分都会扩展。 张力环10将振动膜5向上推动到振动膜第一固定环4的上表面,以向振动膜5施加一定的张力。这里,由于线膨胀比小于振动膜的金属 使用第一固定环4,它们的膨胀将不相似,并且由于温度升高引起的张力环10的圆柱方向的延伸小于振动膜第一固定环4的伸长。因此,施加的张力 由于张力环10的振动膜5与室温相比较小,因此随着温度的上升而与振动膜的延伸一起也越来越小。
