Abstract
带凸缘蘑菇状防噪声耳塞，属于防噪声护耳装
置。本耳塞采用带凸缘薄膜的蘑茹状结构，体壁内外
有空腔可压缩，耳塞由以树脂为主的合成材料制成。
这种结构设计可大大提高耳塞的隔声防噪性能，使规
格单一化，佩戴无方向性，使用舒适方便。
Description
本实用新型属于防噪声护耳装置。
目前采用的防噪声耳塞规格繁多，方向性强，适配性和防噪效果欠佳。
本实用新型的目的是提供一种单规格、防噪声性能良好、佩戴舒适、使用方便的护耳装置。
本实用新型所采用的技术途径是耳塞采用带凸缘薄膜的蘑菇状结构。
下面结合附图对本实用新型的结构进行详细描述。
图中：1－塞柄，2－体壁，3－顶腔，4－凸缘。
从图中可见，耳塞顶部为蘑菇状，体壁内外有空腔，体壁下口有一凸缘薄膜。
该结构设计的优点在于隔声防噪性能好，规格单一，适用于大小不同的耳道，佩戴无方向性，使用方便舒适。
由于采用蘑菇状体壁，且体壁内外有空腔可压缩，故体壁的弹性和塑性良好。蘑菇体下沿直径的设计可根据成年人外耳道口的平均直径或最大尺寸采用一种耳塞规格就能较好地适合于外耳道大小不同的人佩戴，实现规格单一化。在耳塞体壁的体口设计一直径为16－20mm的凸缘薄膜，可以增强耳塞体壁口的张力，提高耳塞刚性和耳塞体壁与耳道壁的密封性能，增大声漏阻抗，减小声漏。又因凸缘能较好地遮住外耳道口，故可进一步提高隔声效果。此外，为了提高耳塞的舒适性，体壁长8－12mm，体壁厚0.4－0.6mm为宜。
耳塞材料为以树脂为主的合成材料，质地柔软、皮肤感好。
