The image measuring instrument has penetrated into everyone's life in 3C electronic products, and the rise of wireless Bluetooth headsets has become an indispensable assistant. The quality of the earphone not only affects the use function, but also plays a great role in the health of human hearing. Of course, the quality of the earphone cannot be separated from the confidential protection of the image measuring instrument.
The quality of the earphone is mainly determined by the diaphragm. The distance, thickness, length, width, diameter, uneven pattern and depth of the diaphragm all determine the quality of the diaphragm. The image measuring instrument uses a high-precision CCD image measuring instrument to measure the diaphragm. Accurate measurement is a "axis" for every size detection, for every 0.01 micron, day and night, just to ensure the quality of the earphones and bring consumers a feast of hearing.
