Best Audio Converters for Earphones, Mobiles & Computers
With the growing popularity of different types of audio devices like phones, computers, headphones, and more, there is a need for audio converters to allow compatibility between devices that use different audio jack standards. Audio converters, also known as audio adapters, fill this need by changing the type of audio connector (such as 3.5mm, or 2.5mm) to allow audio sources and headphones/earphones with different jack sizes to be used together. The audio adapter parts can be manufactured by CNC machining and injection molding techniques.
In this article, we will introduce four of the best audio converter options from DDHiFi, a renowned headphone adapter manufacturer. We’ll look at the features, specifications, and uses for each converter.
Production Process of Audio Adapter Transparent Shells/Housings
The main manufacturing process of the PC plastic shell of the headphone converters is injection molding, which includes these basic steps.
1. Design a 3D digital model of the shell using 3D design software based on product functionality and structural requirements.
2. Based on the digital model of the casing, use CNC machine tools to create precise plastic molds in cast iron or steel.
3. Use tools to polish the inner and outer surfaces of the mold, making the surface smooth and free of burrs.
4. Choose suitable PC plastics, such as non-toxic PCs.
5. Fix the modified mold onto the injection molding machine arm system.
6. Transport PC plastic particle raw materials to the melting equipment, heat and melt them into the plastic slurry.
7. In the closed state of the mold, the plastic slurry enters the predetermined mold chamber under high pressure.
8. The inside and outside of the mold are cooled together with the plastic, and the plastic gradually solidifies into shape.
9. After completing the cooling process, the product and the mold should be removed together for subsequent deburring processing.
10. The manufacturing process is completed by checking whether the product’s external dimensions meet the design requirements.
