　　A mechanical noise

　　Two fan wind

　　Miniature fan solve mechanical noise from the fan material necessary, start the assembly, the following factors will cause loud fan

　　1. Sensor IC fan blades hit the miniature magnetic stripe, friction sound

　　2. miniature fan motor component of the ground to the fan coil ---

　　3. The assembly structure wrong size, bearing grinding oil ring

　　4. bearing and shaft material issue itself will generate noise

　　Solve mini fan is a fan of the wind in the design of medium segment

　　Mainly in the blade angles, shapes, and the product's resistance to wind, there is some fine work design, dynamics, mechanics, electronics and other fields, the Chinese mainland has not yet experts and supporting equipment in this area, most of them are anti-shine Japan, Taiwan or fan shape into the same mold cooling fan products

　　Another point to add is that the fan assembly to the micro-miniature projector assembly problems will generate noise
