    • Provided are a variable directional microphone assembly and a method of manufacturing the same, which can achieve miniaturization by mounting microphone devices in a compact structure with a microphone body, and reduce maintenance costs by transmitting a signal through contact using a coil spring for convenient replacement of the microphone device. The variable di¬ rectional microphone assembly includes a printed circuit board including a connection terminal provided to a surface thereof, and a semiconductor integrated circuit device mounted to another surface thereof, a microphone body including a first mounting space for mounting the semiconductor integrated circuit device, two second mounting spaces, and a coil spring insertion hole, the first mounting space being provided to a surface of the microphone body, the second mounting spaces being provided to another surface of the microphone body, two microphone devices mounted to the second mounting spaces, the insertion hole allowing the microphone device to be in contact with the printed circuit board, a coil spring inserted into the coil spring insertion hole to electrically connect the microphone device to the printed circuit board, and a case including a sound hole in a bottom thereof and configured to fix an assembly by inserting the microphone body coupled with the microphone devices and the semiconductor integrated circuit device into the case and then curling the case.
    • 提供了一种可变方向性麦克风组件及其制造方法,其通过将麦克风装置安装在具有麦克风主体的紧凑结构中而实现小型化,并且通过使用螺旋弹簧通过接触传输信号来降低维护成本,以便于更换 麦克风设备。 可变定向麦克风组件包括印刷电路板,其包括设置在其表面上的连接端子和安装在其另一表面上的半导体集成电路器件,麦克风本体包括用于安装半导体集成电路器件的第一安装空间, 两个第二安装空间和螺旋弹簧插入孔,第一安装空间设置在麦克风主体的表面上,第二安装空间设置在麦克风主体的另一个表面上,安装在第二安装空间的两个麦克风装置, 所述插入孔允许所述麦克风装置与所述印刷电路板接触;插入到所述螺旋弹簧插入孔中的螺旋弹簧,用于将所述麦克风装置电连接到所述印刷电路板;以及壳体,其底部包括声孔 并且被配置成通过插入与所述微孔连接的所述麦克风主体来固定组件 一个器件和半导体集成电路器件进入案例,然后卷曲案例。
