After the four lower cover panels 14 are folded and fixed, the lower opening is blocked to form a supporting bottom of the outer box body 1, and the four upper cover panels 13 can block or open the upper opening.

[0052] Specifically, if Figure 2-Figure 5As shown, the first enclosure assembly 212 includes two oppositely disposed first enclosure panels 2121 and two oppositely disposed second enclosure panels 2122. Adjacent first enclosure panels 2121 and second enclosure panels 2122 are coupled and connected.

[0056] Specifically, if Figure 3-Figure 5 As shown, one of the first and second surrounding panels 2121, 2122 having the slot further includes a first panel 21212 and a second panel 21213 spaced apart from each other to form the slot, and an auxiliary buffer structure 2123 is disposed between the first and second panels 21212, 21213. The auxiliary buffer structure 2123 can support the first and second panels 21212, 21213 to prevent them from bending or deformation, and can provide buffering protection for the speaker 100.

[0057] In this embodiment, the first surrounding plate 2121, the second surrounding plate 2122 and the bottom plate 211 are integrally formed, thereby further improving the storage and transportation convenience of the paper packaging box, simplifying the die-cutting process of the paper packaging box, and improving production efficiency. Figure 6 As shown, first surrounding plates 2121 are provided at the left and right ends of the bottom plate 211 , and second surrounding plates 2122 are provided at the upper and lower ends.

The auxiliary buffer structure 2123 is a rectangular parallelepiped structure with a hollow interior. In order to facilitate die-cutting and save materials, the auxiliary buffer structure forming plate 2124 in this embodiment is integrally formed with the first surrounding plate body. Figure 6 The first enclosure plate body and the auxiliary buffer structure forming plate 2124 can be obtained by cutting along the dotted line.

[0059] like Figure 6 As shown, the second surrounding plate 2122 includes a third plate 21222 and a clamping portion forming plate 21223 provided at the left and right ends of the third plate 21222. The third plate 21222 is connected to the bottom plate 211. The clamping portion forming plate 21223 is formed according to the Figure 6 The solid line can be folded to form the clamping portion 21221, and then Figure 6 The second surrounding plate 2122 can be formed by folding the middle solid line.

[0060] In this embodiment, if Figure 6 As shown, the upper and lower ends of the second plate 21213 are provided with bonding parts 21211, and the bonding parts 21211 are folded along the solid line and bonded to the third plate 21222, thereby realizing the formation of the first surrounding component 212.

[0061] Specifically, if Figure 3 As shown, the bottom support cushioning assembly 22 includes a bottom cushioning member 221, which is disposed on the bottom support body 21 and supports the bottom of the speaker 100.

[0066] Specifically, if Figure 3 As shown, the bottom support cushioning assembly 22 further includes side cushioning members 222, which are disposed on the inner sidewalls of the bottom support mechanism 2 and are capable of abutting against the sidewalls of the speaker 100. The side cushioning members 222 protect the sidewalls at the lower end of the speaker 100 from direct external impact or vibration, thereby preventing damage to the delicate components within the speaker 100.

[0067] Specifically, the side buffer 222 is connected to the first surrounding component 212 by snapping. The snapping design of the side buffer 222 and the first surrounding component 212 can ensure a stable connection between the two and prevent the side buffer 222 from shifting during transportation.

[0068] In an optional embodiment, Figure 3As shown, the side buffer member 222 protrudes with a clamping block 2221, and a clamping groove is formed at the bottom of the clamping block 2221.

[0070] In this embodiment, as Figure 9 , Figure 10 shown, the side buffer member 222 includes a first buffer structure 2222 and two second buffer structures 2223 protruding from the first buffer structure 2222. The two second buffer structures 2223 are arranged at intervals, and the side buffer member 222 is integrally in a "U" - shaped structure. Among them, the clamping block 2221 is arranged on the second buffer structure 2223. The first buffer structure 2222, the second buffer structure 2223 and the clamping block 2221 are integrally formed, thereby further improving the storage and transportation convenience of the paper packaging box, and being able to simplify the die - cutting process of the paper packaging box and improve the production efficiency.

[0071] Specifically, as Figure 9 , Figure 10 shown, the side buffer member 222 includes a first buffer structure forming plate 2224 and second buffer structure forming plates 2225 arranged at both ends of the first buffer structure forming plate 2224.

A clamping block forming plate 2226 is cut along the dotted line in Figure 10 on the second buffer structure forming plate 2225, and is folded along the solid line in Figure 10 to form the clamping block 2221.

[0072] In this embodiment, the number of side buffer members 222 is two, which are arranged on the inner side walls of the two second surrounding plates 2122, and together with the auxiliary buffer structure 2123, provide buffering for the side walls of the speaker 100.

[0073] In some embodiments, the structure and forming method of the top support mechanism 3 are exactly the same as those of the bottom support mechanism 2, so the structure and forming method of the top support mechanism 3 will not be elaborated here.

[0074] In this embodiment, the structure and forming method of the top supporting mechanism 3 are similar to those of the bottom supporting mechanism 2, except that: Figure 11-13 As shown, two clamping bosses 3111 are provided on the second top plate 311, which are located on the left and right sides of the first top plate 311, and locking holes 31111 are opened on the opposite sides of the two clamping bosses 3111; the top supporting buffer assembly 32 includes a top buffer part 321, and the top buffer part 321 includes a limiting plate 3211 and two top buffer structures 3212, and two locking tongues 32111 are provided on the limiting plate 3211.
