[0002] Speaker screens are dust-proof mesh covers on equipment speakers. Speaker screens are positioned during the manufacturing process using jigs. A jig is a tool used to clamp or secure workpiece materials during machining. Its function is to clamp and secure the workpiece in a specific position for subsequent processing and handling. Jigs are made of materials such as iron, steel, and high-temperature alloys to ensure they can withstand high temperatures and high pressures, thereby ensuring safety during the production process. Common jigs include disassembly jigs, assembly jigs, welding jigs, dispensing jigs, irradiation jigs, adjustment jigs, and shearing jigs. Jigs play an important supporting role in the product manufacturing process, improving production efficiency and product quality.
