| titleOfInvention | Windproof device for waterproof microphone |
| abstract | (57) [Summary] [Problem] To provide a windshield for a microphone having excellent acoustic characteristics and excellent waterproofness. [Solution] A sound-permeable material (hereinafter referred to as sound-permeable material) such as foamed resin or woven fabric, wire mesh, and nonwoven cloth PTFE (polytetrafluoroethylene) powder having a contact angle to water of 100 degrees or more and a molecular weight of about 8000, with a weight fraction of 80 ± 10% and a fucavinylidene of 18 on the inner wall surface and / or the front surface of the opening of the material. A mixture of ± 5% and 2 ± 1% of perfluoroether was diluted with butyl acetate and stirred with a ball mill, or PTFE (polytetrafluoroethylene) powder having a molecular weight of about 8,000 was also used in a weight fraction of 79 ± 10%. %, 18 ± 5% of fukavinylidene, 2 ± 1% of perfluoroether, and a mixture of fine particles of photocatalytic anatase-type titanium dioxide, diluted with butyl acetate, and stirred with a ball mill. A windshield device for a waterproof microphone that is coated and thereby forms a single-layer or multilayer windshield. The average radius of these sound-permeable material openings is less than 5 mm |
