Description

一种保密电话话筒
本实用新型涉及通讯设备,确切的说是一种保密电话话筒。
在现代通讯设备中电话的使用越来越普及,已成为人们通讯联络不可缺少的通讯工具,但有时需要紧急磋商以答复对方,但既不想间断通话又不想让对方听到商量对策的过程,这时使用普通电话,需要用手捂住话筒,或调整音量和录音开关进行保密处理,但这样保密的效果不很理想。
本实用新型的目的在于提供一种可以听到对方话音又能保证自己的谈话不被对方听到,且不间断通话的保密电话话筒。
本实用新型的技术方案是在原有普通电话话筒的基础上安装一个按钮,其特征在于:在话筒的受话电路中串联一个微型常闭式按键开关。
本实用新型的优点是通话保密并不间断电话通话,结构简单、使用方便、保密性强。
图1为本实用新型的主视示意图。
图2为本实用新型的内部结构图。
下面通过结构附图对本实用新型作进一步的说明。
由附图可见,本实用新型在话筒的内侧打一开关孔,在话筒[1]的受话电路中串联一个微型常闭式按键开关[6],该开关用螺丝钉固定在话筒[1]内,开关[6]的按键[2]穿过开关孔外露于话筒内侧。使用时,将常闭式开关按下,便可放心商量对策,答复对方时,再按一下常闭式开关,便可和对方通话。
