An online customization platform for headphones based on additive manufacturing

This article proposes a customized online production platform for headphones to solve the problems of discomfort and easy dropping caused by consumers wearing headphones in large quantities using traditional methods. Reverse modeling technology is used to obtain the scanning data of the ear nail cavity, and based on this, the ear machine online customization platform is used to achieve personalized customization of the headphones, and ultimately 3D printing technology is used to complete the production of the headphones. Use Python for secondary development on Geomagic Wrap, and combine it with SceneBuilder to draw a platform page to obtain a user-operable headphone customization platform. Customized headphone production mainly includes three parts: ear nail cavity scanning, parameterized platform modeling, and headphone printing. Using a 3D scanner Artec Space Spider scans the external ear to obtain 3D data of the ear cavity, model repair is performed on a customized platform, and customized earphone models are quickly generated. After conducting finite element simulation analysis on the ear earphone model, we studied the contact pressure between the earphone and the auricle and optimized the earphone parameters. We objectively evaluate the comfort of headphones based on the uniformity of pressure distribution and use this indicator as the goal of simulation optimization.
