[0002] As a common electroacoustic transducer device that converts electrical energy into sound energy, the sound unit plays an indispensable role in the sound amplification system.

[0003] In order to improve the performance of the sound unit, some sound units have begun to adopt a multi-voice coil structure. However, in order to allow the voice coil to penetrate deeper into the magnetic gap, some sound units will set a skeleton structure on the top of the voice coil, such as the Chinese utility model patent with application number 202321609361.7. In this technical solution, each voice coil has a separate skeleton voice coil connected to it, which will undoubtedly increase the components of the sound unit and make the assembly process of the sound unit cumbersome. Moreover, since the skeleton voice coil is a closed structure, the air inside the unit cannot circulate from the top of the voice coil to the two adjacent voice coils, so that the performance of the sound unit is affected to a certain extent.

[0031] From the above description, it can be seen that the beneficial effects of the present invention are: the skeleton 2 in the vibration assembly can connect multiple voice coils 3 at the same time, reducing the components of the vibration assembly, simplifying the structure of the vibration assembly, thereby facilitating the assembly of the vibration assembly, and helping to control the manufacturing cost of the vibration assembly. Moreover, an air flow channel can be formed between the connecting ribs 22 of the skeleton 2 and the diaphragm assembly 1, so that the air in adjacent voice coils 3 can interact through the air flow channel, thereby improving the performance of the sound unit. In addition, the existence of the air flow channel can also reduce the overall weight of the vibration assembly and further improve the performance of the sound unit.

[0032] Furthermore, a single connecting rib 22 connects two voice coils 3 at the same time.

[0041] Furthermore, two opposite sides of the boss 221 are open.

[0042] As can be seen from the above description, the open configuration of the two opposing sides of the boss 221 can significantly reduce the overall weight of the vibration assembly, thereby significantly improving the performance of the sound unit. Furthermore, air flow channels can be formed not only between the bosses 221 but also within the bosses 221, allowing air to flow more smoothly within adjacent voice coils 3.

[0043] Furthermore, the diaphragm assembly 1 includes a dome 11 and a sound membrane 12, the sound membrane 12 includes an inner fixing portion 121, a folding ring portion 122 and an outer fixing portion 123 connected in sequence from the inside to the outside, the inner fixing portion 121 is provided with a window, the dome 11 is provided on the inner fixing portion 121 and covers the window, the top surface of the boss 221 is connected to the dome 11, and the top surface of the mounting portion 24 is connected to the inner fixing portion 121.

[0044] Furthermore, the top surface of the boss 221 is arranged higher or lower than the top surface of the mounting portion 24 .

[0045] From the above description, it can be seen that when the top surface of the boss 221 is higher than the top surface of the mounting portion 24, the mounting portion 24 and the spherical top 11 are located on different sides of the inner fixing portion 121; when the top surface of the boss 221 is lower than the top surface of the mounting portion 24, the mounting portion 24 and the spherical top 11 are located on the same side of the inner fixing portion 121.
