abstract | (57) [Summary] [Problem] To provide a condenser microphone that prevents invasion of water or humid germs. [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 photocatalytic anatase-type titanium dioxide is diluted with butyl acetate, and the mixture obtained by stirring with a ball mill is used as a water-repellent material or a dual-purpose material. As an antifouling material, a sound-permeable material such as a perforated plate, a nonwoven fabric, or a metal net is installed on the front and / or back of the sound hole of the microphone. At least 1.5% of the cubic root of the volume of the space between the sound-permeable material and the microphone diaphragm, And less than 2mm |
