Embodiment 1

[0047] to combine Figure 1 to Figure 5 As shown, a high-efficiency method for manufacturing a moving iron unit diaphragm in this embodiment includes the following process steps:

[0048] S1. Make the diaphragm support sheet group 1 and the diaphragm main sheet group 2, such as figure 1 As shown, the diaphragm support sheet group 1 includes a support strip 11 and two or more diaphragm supports 12 integrally connected to the support strip 11, and both sides of the diaphragm support 12 are formed with folded edges 14 ( see Figure 7 As shown), the bracket strip 11 is also provided with a bracket positioning hole 13, which is used for the positioning of the diaphragm bracket sheet group 1; the diaphragm main body sheet group 2 includes a main body strip 21 and a The diaphragm main body 22 having the same number as the diaphragm support 12 is provided with a main body positioning hole 23 on the main body strip 21 for the positioning of the diaphragm main sheet group 2; specifica...

Embodiment 2

[0059] A high-efficiency method for manufacturing a moving iron unit diaphragm in this embodiment, its process steps are basically the same as in Embodiment 1, the difference is that the diaphragm support 12 in this embodiment is on both sides of the support strip 11, respectively. The spacing is set, and the diaphragm main body 22 is also arranged at equal intervals on both sides of the main material belt 21, that is, the diaphragm support 12 and the diaphragm main body 22 are evenly distributed on both sides of the corresponding material belt according to certain rules, and are not limited to implementation. Single-row design in Example 1; and in this embodiment, four diaphragm supports 12 are arranged at equal intervals on both sides of the support strip 11, and four diaphragm supports are also arranged at equal intervals on both sides of the main body strip 21. The diaphragm main body 22 can complete the production of eight diaphragms 6 in one positioning, and the productio...

Abstract

The invention discloses a method for manufacturing vibrating diaphragms of moving-iron units with high efficiency, and belongs to the technical field of loudspeaker vibrating diaphragms. The method includes the steps of S1, manufacturing a vibrating diaphragm support sheet assembly and a vibrating diaphragm body sheet assembly; S2, sequentially arranging the vibrating diaphragm support sheet assembly, the vibrating diaphragm body sheet assembly and a diaphragm body on a lower mold regardless of the order, and carrying out positioning through support positioning holes and body positioning holes; S3, feeding the lower mold into a hot pressing machine, and connecting the vibrating diaphragm support sheet assembly, the vibrating diaphragm body sheet assembly and the diaphragm body into a whole by assembling a flexible upper mold and the lower mold for hot pressing; S4, taking out the vibrating diaphragm support sheet assembly, the vibrating diaphragm body sheet assembly and the diaphragm body connected into a whole, cutting off redundant portions of the diaphragm body, redundant portions of support strips and redundant portions of body strips, and obtaining the vibrating diaphragms with bent edges and tracks. By means of the method, the multiple vibrating diaphragms can be formed through one-time manufacturing, the technological process is simpler, and the vibrating diaphragm production efficiency is greatly improved; the vibrating diaphragms are once formed, follow-up bending is avoided, the product quality is more stable, and automatic production is easily achieved.

Description

technical field [0001] The invention relates to a method for manufacturing a loudspeaker diaphragm, and more specifically, relates to a method for manufacturing a moving iron unit diaphragm with high efficiency. Background technique [0002] At present, because the performance of the moving iron unit in the middle and high range is better than that of the moving coil unit, the moving iron unit is widely used in many earphones and speakers. The working principle of the moving iron unit is: the moving iron unit uses the basic principle of electromagnetic conversion. When working, the AC current signal passes through the magnetic induction coil, and the coil induces magnetization, which magnetizes the balanced armature (shrapnel) located in the middle of the coil and is magnetized. The balanced armature vibrates up and down in the two permanent magnets according to the principle that the same sex repels each other and the opposite sex attracts each other. The sounding diaphrag...
