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.　©　2024　SPIE.
