description Disclosed is a method for an acoustic device. The method comprises: using a shell injection mold to produce an annular shell of an acoustic device by injection molding, a runner structure formed by injection molding being connected to the periphery of the annular shell; positioning the annular shell, and forming, on the annular shell, a diaphragm for sealing a hollow area of the annular shell; removing the runner structure connected to the periphery of the annular shell; and installing a magnetic circuit system on the annular shell, and mounting a voice coil on the diaphragm. The method has a technical effect that chippings generated by cutting the runner structure can be prevented from being sealed in the diaphragm. La présente invention concerne un procédé pour un dispositif acoustique. Le procédé consiste à: utiliser un moule d'injection de coque pour produire une coque annulaire d'un dispositif acoustique par moulage par injection, une structure de canal formée par moulage par injection étant reliée à la
