Illustrate to Chu technical solution of the present invention, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, a kind of earphone method for making head comprising the steps of:
S1: die sinking carries out the structure of the internal structure of earphone heads, upper housing and lower case with 3D printer and 3D software
It designs and is opened；
It is comprised the steps of: in S1
S101 first prints 3D earphone head model with 3D printer, confirms earphone heads comfort level, analyzes producing feasibility；
S102 such as puts the position of phonation unit with the internal structure of 3D software design earphone heads, under earphone upper casing and earphone
Shell welding position etc.；
S103 assembles loudspeaker, earphone upper casing and earphone with the earphone upper casing and earphone lower casing of 3D printer printing earphone heads
Lower casing welding confirms sound quality；
S104 is opened after sound quality confirms well according to the earphone heads internal structure of design；
S2: injection molding carries out injection parameters setting according to die sinking data and material data, then carries out injection molding,
