[0003] However, there are still some deficiencies and problems in the application of this technical solution, which are specifically reflected as follows: the horn assembly of the loudspeaker must be matched with the horn attachment and the drive head attachment to realize the assembly with the drive assembly; it can be seen from the drawings in the specification of the patent document that during assembly, the horn attachment and the drive head attachment need to be fixed on the horn assembly and the drive assembly respectively, and then the horn attachment and the drive head attachment are assembled together to realize the assembly connection between the horn assembly of the loudspeaker and the drive assembly. This not only has many installation steps, but also requires screwing many screws, which is very time-consuming and labor-intensive, and has a high production cost; at the same time, since the loudspeaker is portable and small in size, its various components are also relatively small, which requires workers to spend more energy to fix the positions of the various components and screw the fixing screws during assembly, so that the assembly is difficult, so the assembly efficiency of the loudspeaker is very low, and it is easy to cause the loss of components. In addition, gaps or cracks are easily left between the horn attachment and the driver head attachment, so that the sound emitted by the driver assembly can easily slip out of these gaps or cracks, causing a loss in sound intensity, making it impossible for all the sound to be transmitted to the horn assembly, affecting the transmission distance and range of the sound output by the loudspeaker.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0029] like Figure 1 , Figure 3 , Figure 4 As shown, a strong sound type portable speaker includes a box body 1, a diffusion horn 2, a reflection horn 3, and a tweeter assembly 4. In order to achieve the purpose proposed by the utility model, the diffusion horn 2 is arranged in the front inner cavity of the box body 1 and assembled with the box body 1 as a whole. A set hole 21 is also provided on the diffusion horn 2. The front end of the tweeter assembly 4 is inserted into the set hole 21 from the rear end of the reflection horn 3. The reflection horn 3 is assembled and connected with the front end of the tweeter assembly 4 from the front inner cavity of the diffusion horn 2. In this way, the reflection horn 3 and the tweeter assembly 4 can be assembled on the diffusion horn 2 without other auxiliary accessories. Not only is the assembly very simple, but the sound generated by the tweeter assembly 4 directly enters the reflection horn 3, which can effectively prevent the loss and loss of sound, thereby avoiding the loss of sound intensity, making the sound emitted by the speaker louder, wider in range, and farther in distance.

[0030] like Figures 6 to 8 As shown, the front end of the tweeter assembly 4 is also provided with a threaded portion 41, and the reflection horn 3 is correspondingly provided with a threaded hole 31 screwed to the threaded portion 41. The reflection horn 3 and the tweeter assembly 4 are connected by threads, which is fast and firm.

[0031] like Figure 7 , Figure 8 As shown, the reflection horn 3 is composed of an outer cylinder shell 32 and an inner cylinder tube 33 disposed in the outer cylinder shell 32, and an annular reflection cavity 34 is further disposed between the inner wall of the outer cylinder shell 32 and the outer wall of the inner cylinder tube 33, and the threaded hole 31 is disposed in the inner cylinder tube 33. The sound is transmitted into the annular reflection cavity 34 through the inner cylinder tube 33, and after multiple reflections and superpositions in the annular reflection cavity 34, the intensity of the sound is improved, thereby enhancing the transmission range and transmission distance of the sound emitted by the speaker.

[0032] like Figure 7 , Figure 8 As shown, the reflection horn 3 is in a cone shape as a whole.

[0033] like Figure 1 , Figure 3 , Figure 6 As shown, a cooling fan mechanism 5 is also installed at the back rear end of the tweeter assembly 4. The cooling fan mechanism 5 can discharge the heat in the box body 1 in time, thereby effectively preventing the temperature in the box body 1 from being too high and affecting the normal operation of the speaker.

[0034] like Figure 1 , Figure 3 , Figure 6As shown, the heat dissipation fan mechanism 5 includes a mounting bracket 51, a heat dissipation fan 52, and a heat sink 53, wherein the heat sink 53 is mounted on the back of the tweeter assembly 4, the mounting bracket 51 is fixedly connected to the heat sink 53, and the heat dissipation fan 52 is mounted on the mounting bracket 51. The tweeter assembly 4 is the core component of the speaker box, so that the heat generated by the tweeter assembly 4 during operation can be taken out of the box body 1 by the fan 52 more promptly, ensuring the stability and reliability of the tweeter assembly 4 and extending the service life of the device. The heat sink 53 helps to further accelerate the heat dissipation of the tweeter assembly 4, thereby further ensuring the working stability and service life of the tweeter assembly 4.

[0035] like Figure 1 , Figure 2 As shown, the box body 1 is an integrated structure, a power supply assembly 7 is installed on one side of the box body 1, and a battery 6 is installed on the other side of the box body 1 near its bottom edge. When the speaker is working, the battery 6 and the power supply assembly 7 will generate a lot of heat. The utility model arranges the battery 6 and the power supply assembly 7 on both sides of the box body 1 respectively, so that when the speaker is working, the heat generated by the battery 6 and the heat generated by the power supply assembly 7 can be prevented from accumulating together, thereby preventing the speaker from being damaged due to overheating.

[0036] like Figure 1 , Figure 2 , Fig. 9 As shown, a first installation cavity 11 is provided on one side of the box body 1, a cavity cover plate 12 is installed on the first installation cavity 11, and the power assembly 7 is arranged on the inner side of the cavity cover plate 12 and fixed to the first installation cavity 11 together with the cavity cover plate 12. In this way, the power assembly 7 can be easily installed or removed through the cavity cover plate 12, so that the power assembly 7 is easy to repair or replace.

[0037] like Figure 1 , Figure 3 , Figure 5 As shown, the second installation cavity 13 is also provided near the bottom edge of the other side of the box 1, and a battery box 14 is also provided in the box 1 corresponding to the second installation cavity 13. The battery 6 is installed in the battery box 14, and the second installation cavity 13 is also covered with a battery cover 15. In this way, the battery 6 is placed at the bottom of the box 1, which can lower the center of gravity of the speaker, help maintain the stability of the speaker when it is placed, and the speaker is not easy to tip over. The battery box 14 can shield the electromagnetic waves emitted by the battery 6 when it is working, thereby preventing it from affecting the normal operation of other electrical components.

[0038] like Figure 1 , Figure 3As shown, a heat dissipation grille 16 is also provided on the front of the box 1. In this way, the heat in the box 1 can be dissipated to the surrounding environment through the heat dissipation grille 16, thereby avoiding overheating inside the box 1. Figure 1 As shown, the heat dissipation grilles 16 are arranged in an array on the front side of the diffusion horn 2 and the bottom of the box body 1, so that air convection channels are formed between the upper and lower heat dissipation grilles 16, which is more conducive to the heat dissipation inside the box body 1.

[0039] like Fig. 9 As shown, a shielding plate 71 is also provided on the power supply assembly 7 to reduce the interference of the power supply assembly 7 to other electrical components during operation.

[0040] like Figure 1 , Figure 3 As shown, mounting plates 17 are provided on the top plate and the bottom plate of the box body 1, respectively, and the upper and lower ends of the mounting bracket 51 are respectively mounted on the two mounting plates 17. In this way, the heat dissipation fan mechanism 5 can be subjected to forces from top to bottom, so that it can be stably mounted inside the box body 1. Mounting holes are provided on the four corners of the heat dissipation fan 52, and mounting holes are also provided on the mounting bracket 51 and the two mounting plates 17 correspondingly. The heat dissipation fan 52 is installed in the box body 1 by screws passing through the mounting holes on the heat dissipation fan 52, the mounting bracket 51 and the two mounting plates 17 in sequence. Since the distance between the top plate and the bottom plate of the box body 1 is greater than the height of the heat dissipation fan 52, the mounting bracket 51 is additionally provided so that the heat dissipation fan 52 can be more firmly mounted in the box body 1, so that the heat dissipation fan 52 is not easy to shake during operation, so that it can work stably for a long time and discharge the heat in the box body 1 to the external environment in time.

[0041] like Figure 1 , Figure 6 As shown, a mounting hole 54 is provided at the center of the heat spreading sheet 53, and a mounting hole 54 is correspondingly provided on the mounting bracket 51. Thus, the mounting bracket 51 and the tweeter assembly 4 can be assembled by screws passing through the mounting hole 54, so that the tweeter assembly 4 is supported by the mounting hole 21 and the mounting hole 54 at the same time, so that the tweeter assembly 4 can be more stably installed on the box 1, which helps to improve its working stability.
