[0002] As a key component of the automobile sound system, the vehicle-mounted loudspeaker bears the important function of converting electrical signals into sound signals. In the vehicle-mounted loudspeaker, the diaphragm is the core component of sound production, and its quality directly affects the sound effect. During the manufacturing process of the vehicle-mounted loudspeaker, some microscopic defects may occur, such as uneven coating on the surface of the diaphragm, or tiny particles, bubbles, etc. The optical microscope plays a key role in detecting these microscopic problems, as it helps the detector observe the state of the diaphragm coating. When detecting the vehicle-mounted loudspeaker, it is usually placed at the bottom of the detector.
