Embodiment 1
[0033] Such as Figure 1 to Figure 3 As shown, the sound generating device provided by the present invention includes a vibrating assembly and a magnetic circuit assembly 3, wherein the vibrating assembly includes a diaphragm 1 and a voice coil 41 combined with the lower side of the diaphragm 1, wherein "up" and "down" are represented by figure 2 The structure shown prevails. The diaphragm 1 includes a middle part 11 at the middle position and a ring part 12 at the edge, wherein the middle part 11 is a hard material, and the strength of the middle part 11 is greater than that of the ring part 12. During the vibration process, the middle The portion 11 is not deformed. The magnetic circuit assembly 3 is located under the diaphragm 1. The magnetic circuit assembly 3 is a dual magnetic circuit structure including a central magnetic circuit at the center and a side magnetic circuit at the edge. A voice coil is formed between the central magnetic circuit and the side magnetic cir...
Embodiment 2
[0057] Such as Figure 4 As shown, there are three main differences between the present embodiment and the implementation of Lee 1. The connection part 7 is a hollow columnar structure, the flexible deformation part 2 is combined with the lower surface of the upper magnetically conductive plate 311, and the flexible deformation part 2 is connected with the upper magnetic plate 311. A support member 5 is provided between the magnetic conductive plates 311 .
[0058] The connection part 7 of this embodiment is a hollow columnar structure, the upper end surface of the connection part 7 is located on the same plane, and the lower end surface of the connection part 7 is located on the same plane. This structure is beneficial to the connection part 7 and the planar middle part 11 and The planar intermediate portion 21 is fixedly joined. Wherein, the upper end surface of the connecting part 7 is fixedly combined with the middle part 11 of the diaphragm 1, and the lower end surface o...
