The pressing ring 9 will first contact the top of the speaker. As the stamping die 6 moves downward, the spring 10 is compressed. When the stamping die 6 moves downward to fit the opening die 19, the punching operation is completed. The speaker body can be effectively positioned through the pressing ring 9 and the supporting air cushion 20 inside the speaker, thereby avoiding the displacement of the speaker during the punching process, thereby ensuring the accuracy of the punching.

[0024] During the punching process, the second pneumatic cylinder 13 is started, so that the second pneumatic rod 14 drives the fixing frame 15 and the heating plate 16 to move until the heating plate 16 moves to contact the top of the speaker, thereby heating the speaker. After heating, the second pneumatic cylinder 13 is started again to keep the heating plate 16 away from the speaker body so as not to interfere with the punching operation. At the same time, heating by the heating plate 16 can avoid the plastic speaker from being cracked by stamping, thereby ensuring the production quality of the speaker.
