| abstract | (57) [Summary] [Problem] To provide a condenser microphone that prevents intrusion of water or humid humid bacteria. [Solution] PTFE (polytetrafluoroethylene) powder having a molecular weight of about 8000 is 80 ± 10% by weight and a hooker. 18 ± 5% of vinylidene and 2 of perfluoroether A mixture of ± 1% was diluted with butyl acetate and stirred with a ball mill, or PT having a molecular weight of about 8,000. FE (polytetrafluoroethylene) powder in a weight fraction of 7 A mixture of 9 ± 10%, 18 ± 5% of fukavinylidene, 2 ± 1% of perfluoroether, and fine particles of an anatase type titanium dioxide photocatalyst is diluted with butyl acetate, and stirred with a ball mill to obtain a water-repellent material or A sound-permeable material such as a perforated plate or non-woven fabric installed on the front and / or back of the sound hole of the microphone is also coated as an antifouling material. |
