    • In order to automate a microphone assembly process including a dust-proof treatment, an object of the present invention is to provide a dust-proof microphone having a configuration suitable for automated assembly. According to the present invention, a microphone has a plate-like or film-like dust-proof section that is disposed in a conductive housing (capsule) having a sound aperture and covers the sound aperture. The dust-proof section has a plurality of pores at least in a region corresponding to the sound aperture, and the dust-proof section further has a nonporous region. In the case of an electret condenser microphone, from the viewpoint of performance of the microphone, the dust-proof section is conductive. In addition, taking into account a soldering in a reflow furnace, the dust-proof section is heat-resistant. Each pore is desirably designed taking into account the environment for the usage of the microphone. However, if it is supposed that the microphone is used near one's mouth, each pore has an area of 0.01 mm2 or less. In addition, to enhance the dust-proof effect, the pores may be subjected to a water-repellent treatment.
    • 为了使包括防尘处理的麦克风组装过程自动化,本发明的目的是提供一种具有适于自动组装的结构的防尘麦克风。 根据本发明,麦克风具有设置在具有声孔并且覆盖声孔的导电壳体(胶囊)中的板状或膜状防尘部。 防尘部至少在与声孔对应的区域中具有多个孔,防尘部还具有无孔区域。 在驻极体电容麦克风的情况下,从麦克风的性能的观点出发,防尘部是导电的。 此外,考虑到回流炉中的焊接,防尘部分是耐热的。 理想地设计每个孔,考虑到麦克风的使用环境。 然而,如果假设麦克风在嘴口附近使用,每个孔的面积为0.01mm以下。 此外,为了提高防尘效果,可以对该孔进行防水处理。

    • A unidirectional microphone includes a cylindrical capsule, a front plate blocking one end of the cylindrical capsule, a front plate sound hole formed in the front plate, a vibrating membrane and a first rear pole plate that are housed in the cylindrical capsule and form capacitance, a substrate blocking another open end of the capsule, and a rear plate sound hole formed in the substrate. The front plate sound hole and the rear plate sound hole are placed on mutually opposite sides of a central axis of the capsule so as to be offset relative to the central axis. The directional axis can be significantly offset relative to the central axis of the microphone using the microphone alone.
