[0002] Traditional buzzer such as figure 1 As shown, the coil group 4 is electrically connected to the pin 1 through the PCB board 9. This structure will cause the production process of the buzzer to be cumbersome and have a certain impact on the operation of the buzzer; specifically, the general production process is as follows: ① Rivet the pin 1 on the PCB board 9; ② ​​After the winding of the coil group 4 is completed, solder the start and end of the coil group 4 to the corresponding pads on the PCB board 9, so that the coil group 4 and the pin 1 are electrically connected to each other ;③ Glue the PCB board and the support coil 9, and wait for the glue to solidify; ④After 3-4 hours, after the glue is solidified, assemble the components such as the magnetic ring 6, the vibrating plate 7 and the outer shell 8 in order, and then Dot glue on the edge again to seal and plug the hole, and then epoxy potting can be done after curing

In the traditional buzzer, since the pin 1 and the coil group 4 are electrically connected to each other through the PCB board 9, that is, the pin 1 and the coil group 4 need to be connected to the PCB board 9 through a welding process, which makes the production process cumbersome. The connection method often directly affects the electrical connection effect because of the welding quality; in addition, in the production process, the PCB board 9 needs to be glued around the periphery (that is, the above step ③, since the bonding object is the PCB board 9, the glue used is only Special glue can be selected, the curing time of the glue is long), during which it is necessary to wait for the glue to completely cure before proceeding to the next step, so the production of traditional buzzers cannot achieve uninterrupted assembly line production, and the production efficiency is low; In addition, PCB Board 9 electrically connects pin 1 to coil group 4 by printing related circuits, and the printed circuit will increase the resistance between pin 1 and coil group 4, and reduce the current reaching coil group 4, resulting in a decrease in power and power consumption. loss
