一种传声器极头后极板防潮结构,包括由圆形极板和套在其外周的聚甲醛环组成的后极板,在该极板外沿与聚甲醛环之间的连接面的中间设有相互吻合的凸缘和凹槽,其特征在于,在所述的极板外沿与聚甲醛环之间的连接面的外侧设有环形凹槽。本实用新型专利技术的优点是:这种结构的改进,基本上以原有的极头结构为基础,不涉及增减零件,故产品成本较之前不会有大的变化。环形凹槽中的空气环对垫片和后极板进行物理隔离,减弱潮气对后极板的影响,从而避免潮湿噪声的产生。极头的环境适应性得到有效增强,尤其是在潮湿环境下的适应性。产品的使用环境更加宽,产品的稳定性更强。(*该技术在2023年保护过期,可自由使用*)

Damp proof structure of microphone pole end plate

A microphone after the plate moistureproof structure, including the back plate by a circular plate and set in the periphery of the POM ring, flange and the groove is matched between the plate and the outer edge of the POM ring connecting surface is arranged in the middle, which is characterized in the connection between the lateral surface and the outer edge of the plate polyoxymethylene ring is provided with an annular groove. The utility model has the advantages that the improvement of the structure is based on the original pole head structure, and does not involve the increase or decrease of parts. The air ring in the annular groove is physically isolated from the shim plate and the back plate, and the influence of the moisture on the back plate is weakened, so as to avoid the generation of damp noise. The environmental adaptability of the polar head is enhanced effectively, especially in humid environment. The use of the product environment is more wide, more stable product.
