In an extremely involuntary industry, the commercial and product value of a flagship headset needs to be enhanced through precise positioning and differentiation strategies, while building a recognizable product image. AI translation recording has become the new inner roll direction of flagship earphones of major manufacturers, taking into account the product function and beautiful appearance. The cover opening form is designed as rotating cover opening. Innovative product experience also solves the problem of all-round conference radio without dead angle. In order to have a better texture and feel of the product, the use of high-precision laser texture, perfect presentation on the 3d surface, the texture depth control at about 25-30um, the texture is still clearly visible after multi-layer spraying. The innovation of flagship tws headphones is limited by the shape of auricle and product positioning. The shapes of the front cavity and the middle shell become the same on the premise of meeting ergonomics. deco parts become the entry point for appearance differentiation. In mid -2024, it is not common for most competing products to realize high light and dumb surface on the same part. There are many forms that can be realized. Under comprehensive consideration, ncvm carbon dioxide laser dummy surface was selected, the finished product of ncvm is placed under the purple light laser engraving machine through the rotating jig, and the large surface is carved out of the highlighted logo through the laser, forming a delicate light dummy body, and improving the recognition and refinement of the whole machine. Compared to other light-dumb homologs, this process is made short, relatively low cost, and high yield. The disadvantage is that the matte texture of laser carving cannot be accurately controlled.
