[0046] According to some embodiments of the present invention, referring to Figure 4 , the high - frequency signal direction - adjusting unit 140 further includes: a horn housing 142, and the horn housing 143 is fixedly connected to the mounting panel 120; the high - pitched horn 141 and the rotating assembly 142 are both arranged in the cavity of the horn housing 143, and the rotating assembly 142 is fixedly connected to the horn housing 143. The horn housing 143 is mainly used to support the high - frequency signal direction - adjusting unit 140 to make the structure more stable.

[0047] It should be noted that the horn housing 143 has a side wall with a groove. The groove is used to clamp the second connecting member 1442 of the first connecting assembly 144 and the fourth connecting member 1452 of the second connecting assembly 145, and its function is to fix the horn housing 143 so that there is no mounting gap between the horn housing 143 and the mounting panel 120, and the two are tightly fixed. There is no limitation on the shape of the groove, as long as it matches the shapes of the second connecting member 1442 and the fourth connecting member 1452.

[0048] According to some embodiments of the present invention, referring to Figure 4, the high-frequency signal pointing unit 140 further includes: a first connection component 144 and a second connection component 145 respectively disposed on the left and right sides of the tweeter horn 141. The first connection component 144 and the second connection component 145 are used to connect the rotating component 142 and the mounting panel 120.

[0049] According to some embodiments of the present invention, referring to Figure 6 , the first connection component 144 includes: a first connecting member 1441 and a second connecting member 1442. The first connecting member 1441 is fixedly connected to the rotating component 142, one end of the second connecting member 1442 is detachably connected to the first connecting member 1441, and the other end of the second connecting member 1442 is detachably connected to the mounting panel 120.

[0051] It should be noted that the present invention embodiment does not limit the shapes and sizes of the first connecting member 1441 in the first connection component 144 and the third connecting member 1451 in the second connection component 145, but does not affect the rotation of the tweeter horn 141.

[0052] According to some embodiments of the present invention, referring to Figure 3 , a first mounting hole 121 is provided on the mounting panel 120, and the tweeter horn 141 passes through the first mounting hole 121 and is rotatably connected to the rotating component 142. The first mounting hole 121 enables the tweeter horn 141 to rotate through the mounting panel 120, which limits the rotation range of the tweeter horn 141 to a certain extent, avoids the downward swing of the tweeter horn's opening due to gravity, and plays a supporting role.

[0053] It should be noted that when the shape of the first mounting hole 121 and the shape of the tweeter horn 141's speaker are both circular, the diameter of the first mounting hole 121 should be greater than the diameter of the opening of the tweeter horn 141 to reserve space for the adjustment of the angle of the tweeter horn 141, and the rotation range of the tweeter horn 141 is 15 degrees up and down.

[0054] According to some embodiments of the present utility model, the shape of the first mounting hole 121 may be the same as or different from the shape of the horn opening of the high-frequency horn 141. When the shape of the first mounting hole 121 is different from the shape of the horn opening of the high-frequency horn 141, the shape of the mounting hole 121 does not limit the connection and installation of the non-horn-opening part of the high-frequency horn 141 to the rotating assembly 142, nor does it affect the rotation range of the high-frequency horn 141. For example, when the shape of the first mounting hole 121 is circular and the shape of the horn opening of the high-frequency horn 141 is hexagonal, the diameter of the first mounting hole 121 should be greater than the maximum width of the horn opening of the high-frequency horn 141, without affecting the rotation range of the high-frequency horn 141; when the shapes of both the first mounting hole 121 and the horn opening of the high-frequency horn 141 are hexagonal, the maximum width of the first mounting hole 121 should be greater than the maximum width of the horn opening of the high-frequency horn 141, without affecting the rotation range of the high-frequency horn 141. Therefore, the embodiments of the present utility model do not specifically limit the shapes of the first mounting hole 121 and the horn opening of the high-frequency horn 141.

The four bass horn units 130 are provided as low-frequency sound sources to generate low-frequency signals. The high-frequency horn 141 serves as a high-frequency sound source to generate high-frequency signals. The four bass horn units 130 being sequentially arranged around the high-frequency signal directivity adjustment unit 140 can separate the high- and low-frequency signals for propagation, improving the overall sound quality and ensuring high clarity and accuracy of the sound during transmission.

[0056] According to some embodiments of the present utility model, referring to Figure 3 , four second mounting holes 121 are further provided on the mounting panel 120, and each bass horn unit 130 passes through a second mounting hole 121 and is fixedly connected to the mounting panel 120. The second mounting holes 121 are used to fix the bass horn units 130.

[0057] It should be noted that the four bass horn units 130 respectively pass through the second mounting holes 121 and are fixed at the lower position of the mounting panel 120 to prevent the four bass horn units 130 from obstructing the rotation of the high-frequency horn. The arrangement manner of the four bass horn units 130 can be around the high-frequency signal directivity adjustment unit 140 or can be in other arrangement manners. The number of bass horn units 130 can be multiple, not limited to four.

[0058] According to some embodiments of the present utility model, referring to Figure 2, handle holes 111 are provided on the side walls on the left and right sides of the mesh panel 110, which can facilitate the lifting of the speaker 100 and the disassembly of the mesh panel 110, and facilitate the adjustment and rotation of the high-frequency horn 141.

[0059] According to some embodiments of the present invention, referring to Figure 1 , notches are provided on the edges of the side walls on the left and right sides of the housing 150. When the surface of the mesh panel 110 is flush with the edges of the side walls on the left and right sides of the housing 150, the notches of the housing coincide with the handle holes 111 of the mesh panel. Such a design is also for the convenience of carrying and disassembling the speaker.

[0060] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings.
