[0051] The embodiments of the present application disclose an angle adjusting device 1, which can be applied to a loudspeaker angle adjusting system 2 having a plurality of linear array connected loudspeaker bodies 20 to realize angle adjustment between two adjacent loudspeaker bodies 20. Specifically, in actual settings, the angle adjusting device 1 can be arranged on each loudspeaker body 20, in other words, when the loudspeaker angle adjusting system 2 has a plurality of linear array loudspeaker bodies 20, the angle adjusting device 1 can be arranged on each loudspeaker body 20.

[0052] The technical solutions of the present application will be further illustrated by the following drawings.

[0053] Specifically, please refer to Figures 1 to 3 , the angle adjusting device 1 comprises a fixed support 10, a movable component 11 and a clamping structure 12. The fixed support 10 is used to set the angle adjusting device 1 on the corresponding speaker body 20 (see Figure 7 ), and the fixed support 10 is provided with a mounting cavity 100 and a tooth-shaped groove 101, the tooth-shaped groove 101 is in communication with the mounting cavity 100, and the opening direction of the tooth-shaped groove 101 is perpendicular to the opening direction of the mounting cavity 100. The movable component 11 is slidably arranged in the mounting cavity 100, and the movable component 11 comprises opposite first and second ends 111 and 112. The movable component 11 can slide relative to the mounting cavity 100 so that the first end 111 of the movable component 11 is located outside the opening of the mounting cavity 100, so that the first end 111 of the movable component 11 and the mounting cavity 100 of another speaker body 20 adjacent to the speaker body 20 where the movable component 11 is located can be rotatably connected. The second end 112 of the movable component 11 is provided with a first positioning member 110, and the first positioning member 110 is slidably arranged in the tooth-shaped groove 101. The clamping structure 12 is arranged on the fixed support 10, and the clamping structure 12 is connected to the first positioning member 110, and the clamping structure 12 is engaged with the tooth-shaped groove 101.

[0054] Specifically, as known from the foregoing, the angle adjusting device 1 can be applied to a speaker angle adjusting system 2, and the angle adjusting device 1 is arranged on each speaker body 20. Therefore, the above-mentioned movable component 11 can slide relative to the mounting cavity 100 so that the first end 111 of the movable component 11 is located outside the opening of the mounting cavity 100, so that the first end of the movable component 11 and the mounting cavity 100 of another speaker body 20 adjacent to the speaker body 20 where the movable component 11 is located can be rotatably connected. Specifically, taking two adjacent speaker bodies 20 as an example, the first speaker body 20 and the second speaker body 20, the first end 111 of the movable component 11 on the first speaker body 20 can be slid to be located outside the opening of the mounting cavity 100, so that the first end 111 of the movable component 11 on the first speaker body 20 can extend into the mounting cavity 100 on the second speaker body 20, so that the movable component 11 and the mounting cavity 100 can be rotatably connected. Specifically, in actual connection, a first rotating hole 111a can be arranged on the first end 111 of the movable component 11, and a second rotating hole 100c can be arranged on the mounting cavity 100, and the first rotating hole 111a can be used to rotatably connect the second rotating hole 100c of the mounting cavity 100 of another speaker body 20 adjacent to the speaker body 20 where the movable component 11 is located through a fixed pin 233.

[0055] It can be seen that, by adjusting the position of the clamping structure 12 engaged with the tooth-shaped groove 101, the first positioning member 110 arranged on the movable component 11 can slide relative to the mounting cavity 100, thereby driving the first end 111 of the movable component 11 to slide relative to the mounting cavity 100, so as to adjust the length of the first end 111 of the movable component 11 extending out of the opening of the mounting cavity 100, and thus achieve the purpose of adjusting the distance between the two adjacent speakers. When the adjustment is completed, the first positioning member 110 can be kept at the current position relative to the tooth-shaped groove 101 by the clamping structure 12 engaged with the tooth-shaped groove 101 and connected to the first positioning member 110.

[0056] In some embodiments, when the angle adjusting device 1 is installed on the speaker body 20, the fixed support 10 is mainly installed on the speaker body 20. Specifically, the fixed support 10 can be fixed to the speaker body 20 by screwing, so as to facilitate the disassembly and assembly of the fixed support 10 and the speaker body 20, and improve the installation stability and reliability of the fixed support 10 installed on the speaker body 20.

[0057] Further, the fixed support 10 includes a plate-shaped portion 102 and a strip-shaped portion 103. The plate-shaped portion 102 can be a square plate-shaped structure, and is used to be fixed to the speaker body 20. The strip-shaped portion 103 is arranged on the plate-shaped portion 102, and is provided with the mounting cavity 100 and the tooth-shaped groove 101. Specifically, the strip-shaped portion 103 is a long strip-shaped protrusion which can be integrally formed on the plate-shaped portion 102. The mounting cavity 100 is arranged along the length direction of the strip-shaped portion 103. The tooth-shaped groove 101 is arranged on the side surface of the strip-shaped portion 103, and can penetrate through the two opposite sides of the strip-shaped portion 103 along the first direction X, i.e., the first direction X is the width direction of the strip-shaped portion 103. In this way, the opening direction of the mounting cavity 100 and the opening direction of the tooth-shaped groove 101 are perpendicular, so as to make the sliding of the movable component 11 relative to the mounting cavity 100 and the connection of the clamping structure 12 with the tooth-shaped groove 101 not interfere with each other.

[0058] Further, when the strip-shaped portion 103 is arranged in the mounting cavity 100, considering that the mounting cavity 100 needs to realize the sliding connection of the movable part 11 and the extension of the movable part 11 on another adjacent speaker body 20, therefore, as an optional embodiment, the mounting cavity 100 can penetrate the strip-shaped portion 103 along the second direction Y, that is, the second direction Y is the length direction of the strip-shaped portion 103, and the mounting cavity 100 is a penetrating cavity. In this embodiment, the mounting cavity 100 has opposite first and second openings 100a and 100b, and the movable part 11 can slide relative to the mounting cavity 100 to the first end 111 of the movable part 11 outside the first opening 100a. A limiting part 104 can also be arranged in the mounting cavity 100, which is located at one end of the mounting cavity 100 with the second opening 100b, and the limiting part 104 is used to limit the position of the movable part 11 of another speaker body 20 adjacent to the speaker body 20 where the limiting part 104 is located extending into the second opening 100b.

[0059] Specifically, taking two adjacent speaker bodies 20 as the first speaker body 20 and the second speaker body 20, and the second speaker body 20 is connected above the first speaker body 20, the movable part 11 on the first speaker body 20 is the first movable part 11, the mounting cavity 100 on the first speaker body 20 is the first mounting cavity 100, the movable part 11 on the second speaker body 20 is the second movable part 11, and the mounting cavity 100 on the second speaker body 20 is the second mounting cavity 100 as an example. The first end 111 of the first movable part 11 on the first speaker body 20 extends out through the first opening 100a of the first mounting cavity 100 and extends into the second mounting cavity 100 through the second opening 100b of the second mounting cavity 100 on the second speaker body 20. Since the limiting part 104 is arranged in the second mounting cavity 100, the limiting part 104 can limit the position of the first movable part 11 extending into the second opening 100b of the second mounting cavity 100, so that the first end 111 of the first movable part 11 is determined with the rotating connection position of the second mounting cavity 100.

[0060] Further, the limiting part 104 can be a limiting block, a through hole is arranged in the strip-shaped portion 103 close to the second opening 100b, and the first end 111 of the movable part 11 can extend into the through hole through the second opening 100b and be connected with the pin 2113 to realize the rotating connection of the first end 111 of the movable part 11 with the second mounting cavity 100.

[0061] As another alternative implementation, the mounting cavity 100 may not completely penetrate the strip-shaped portion 103. That is, the mounting cavity 100 does not penetrate the strip-shaped portion 103 along its length. In this case, a groove may be provided at the end of the strip-shaped portion 103 opposite to the end where the mounting cavity 100 is provided. This groove can also be used for the first end 111 of the movable part 11 on the adjacent speaker body 20 to extend into and rotate.

[0062] Combination Figure 4 As shown, where, Figure 4 (a) shows a left view of the fixed bracket 10, (b) shows a front view of the fixed bracket 10, and (c) shows a right view of the fixed bracket 10. In some embodiments, the angle adjustment device 1 in this application mainly adjusts the length of the first end 111 of the movable part 11 extending out of the mounting cavity 100 by engaging the toothed groove 101 with the clamping structure 12, thereby adjusting the angle between two adjacent speaker bodies 20. Based on this, in order to improve the angle adjustment accuracy of the angle adjustment device 1, the fixed bracket 10 (specifically, on the strip portion 103) is provided with an angle mark 105. The angle mark 105 can be used to identify the angle between the speaker body 20 where the angle mark 105 is located and another adjacent speaker body 20 when the clamping structure 12 is engaged with the toothed groove 101 at different positions. Specifically, the angle mark 105 can be set on the strip portion 103 by screen printing or laser engraving. The angle mark 105 can be located on the outer periphery of the toothed groove 101. The angle marker 105 can be one or more. For example, there can be three angle markers 105: a first angle marker 105a, a second angle marker 105b, and a third angle marker 105c. The first angle marker 105a and the third angle marker 105c are respectively located on two opposite sides of the strip portion 103 along the second direction Y. Figure 4 As shown in (a) and (c), the second angle marker 105b is located on the side of the strip-shaped portion 103 away from the plate-shaped portion 102, as... Figure 4 As shown in (b) above. By providing multiple angle markers 105, the operator can see the angle marker 105 regardless of the angle from which they operate, thus providing a reference for the operator's operation. It is understood that in other embodiments, the angle marker 105 may also be a single one, which may be provided, for example, on the side of the strip portion 103 away from the plate portion 102, or it may be provided on the surface of the strip portion 103 where the toothed groove 101 is provided.

[0063] Further, the angle value of the angle identifier 105 can be 0°-5°. Exemplary values can be 0°, 0.5°, 1°, 1.5°, 2°, 2.5°, 3°, 3.5°, 4°, 4.5°, 5°, etc. In this way, the angle adjustment span of the angle adjustment device 1 is smaller, and the angle adjustment is more accurate.

[0064] Please refer to Figure 3 、 Figures 5 to 7 In some embodiments, the movable component 11 is a long strip-shaped plate structure, and the shape of the movable component 11 is substantially adapted to the shape of the mounting cavity 100, so as to be slidably connected to the mounting cavity 100. As described above, the first positioning member 110 is arranged at the second end 112 of the movable component 11, and the first positioning member 110 is located in the area where the tooth-shaped groove 101 is located, so that the first positioning member 110 can be located in the tooth-shaped groove 101 or protrude from the tooth-shaped groove 101, so as to be connected with the clamping structure 12. Specifically, the first positioning member 110 can be a long columnar structure arranged on the movable component 11, and in order to facilitate the installation of the movable component 11 in the mounting cavity 100, the first positioning member 110 can be arranged at the second end 112 of the movable component 11 in a detachable manner. In actual arrangement, the first positioning member 110 can be arranged at the second end 112 of the movable component 11 by means of screws or buckles.

[0065] In some embodiments, the clamping structure 12 includes a first clamping assembly 12a and a second clamping assembly 12b arranged on the fixed support 10, the first clamping assembly 12a and the second clamping assembly 12b are respectively connected to the two opposite sides of the first positioning member 110, and the first clamping assembly 12a and the second clamping assembly 12b are respectively engaged with the tooth-shaped groove 101. In this way, by the cooperation of the first clamping assembly 12a and the second clamping assembly 12b, the position of the first positioning member 110 relative to the tooth-shaped groove 101 can be limited. It can be understood that in other embodiments, the clamping structure 12 can also include only one clamping assembly, and the engagement connection between the one clamping assembly and the first positioning member 110 and the tooth-shaped groove 101 can be realized.

[0066] Further, the first clamping assembly 12a includes a first connecting member 120 and a first clamping member 121, the first connecting member 120 is arranged on the fixed support 10, the first clamping member 121 is arranged on the first connecting member 120, the first clamping member 121 is engaged with the tooth-shaped groove 101, and the first clamping member 121 is connected to one side of the first positioning member 110. Specifically, the first connecting member 120 is arranged on the strip-shaped portion 103 of the fixed support 10, so as to be connected to the strip-shaped portion 103 of the fixed support 10, preventing the first clamping assembly 12a from being separated from the fixed support 10.

[0067] Correspondingly, the second clamping assembly 12b comprises a second connecting member 122 and a second clamping member 123. The second connecting member 122 is arranged on the fixing support 10, and the second clamping member 123 is arranged on the second connecting member 122. The second clamping member 123 is engaged with the tooth-shaped groove 101, and the second clamping member 123 is connected to the other side of the first positioning member 110. Specifically, the second connecting member 122 is arranged on the strip-shaped portion 103 of the fixing support 10, so as to be connected to the strip-shaped portion 103 of the fixing support 10, thereby preventing the second clamping assembly 12b from being separated from the fixing support 10.

[0068] Further, the first connecting member 120 has a first connecting space 120a. As known from the foregoing, the tooth-shaped groove 101 extends through the two opposite sides of the strip-shaped portion 103 along the first direction X. Therefore, the first clamping member 121 can be arranged in two, and the two first clamping members 121 are arranged in the first connecting space 120a and are located on the two opposite sides of the first connecting space 120a, respectively. The two first clamping members 121 are respectively used for engaging connection with the two opposite sides of the tooth-shaped groove 101. Specifically, when the first connecting member 120 has the first connecting space 120a, the first connecting space 120a can be arranged corresponding to the strip-shaped portion 103 of the fixing support 10. Therefore, the first connecting space 120a can avoid the strip-shaped portion 103, so that the two first clamping members 121 in the first connecting space 120a can be respectively located on the two sides of the strip-shaped portion 103 along the width direction of the strip-shaped portion 103, so as to be respectively engaged with the two sides of the tooth-shaped groove 101.

[0069] Correspondingly, the second connecting member 122 has a second connecting space, and the second clamping member 123 is also two. The two second clamping members 123 are arranged in the second connecting space and are respectively located on the two opposite sides of the second connecting space. The two second clamping members 123 are respectively used for engaging connection with the two opposite sides of the tooth-shaped groove 101. Specifically, along the length direction of the strip-shaped portion 103, the two second clamping members 123 are located below the two first clamping members 121, so that the two first clamping members 121 and the two second clamping members 123 are respectively located on the two opposite sides of the first positioning member 110.

[0070] In some embodiments, the first connecting member 120 can be a frame structure or a structure formed by multiple components. Specifically, the first connecting member 120 includes a first fixed portion 120b and a first movable portion 120c, and two first clamping members 121 are respectively arranged on the first fixed portion 120b and the first movable portion 120c. The first movable portion 120c is slidably connected to the first fixed portion 120b along the first direction X, and the first connecting space 120a is formed between the first movable portion 120c and the first fixed portion 120b. By arranging the first movable portion 120c and the first fixed portion 120b with the first clamping members 121 respectively, and slidably connecting the first movable portion 120c to the first fixed portion 120b along the first direction X, the distance between the two first clamping members 121 arranged on the first movable portion 120c and the first fixed portion 120b can be adjusted by adjusting the sliding position of the first movable portion 120c relative to the first fixed portion 120b, and thus the engagement state of the two first clamping members 121 with the two opposite sides of the tooth-shaped groove 101 can be adjusted.

[0071] Specifically, the first fixed portion 120b can be a long strip-shaped plate structure, which can include a first portion 1200 along the length direction thereof and a second portion 1201 connected to the first portion 1200. The first clamping member 121 can be arranged on the first portion 1200, and the first movable portion 120c can be connected to the second portion 1201. More specifically, the first clamping member 121 can be fixed on the first portion 1200 by screwing, buckling or bonding, etc. In actual arrangement, in order to facilitate the adjustment of the position of the first clamping member 121 on the first portion 1200 and improve the reliability of the fixation of the first clamping member 121 on the first portion 1200, the first clamping member 121 can be fixed on the first portion 1200 by screwing. In addition, in order to position the fixed position of the first clamping member 121 on the first portion 1200, the first portion 1200 can be provided with a first positioning portion 1200a. For example, the first positioning portion 1200a can be a positioning groove, and the first clamping member 121 can be at least partially embedded in the first positioning portion 1200a, so as to realize the positioning of the first clamping member 121 on the first portion 1200.

[0072] Further, the second portion 1201 can be formed by a groove formed on the first fixed portion 120b, so that the upper surface of the second portion 1201 is lower than the upper surface of the first portion 1200, i.e., there is a height difference between the second portion 1201 and the first portion 1200, so that the first movable portion 120c has more sliding space when being slidably connected to the second portion 1201.

[0073] In some embodiments, in order to form the first connecting space 120a between the first movable part 120c and the first fixed part 120b, the first movable part 120c comprises a first protruding part 1202 and a first flat part 1203, the first protruding part 1202 is slidably connected to a second part 1201 of the first fixed part 120b, and the first flat part 1203 is arranged on a side of the first protruding part 1202 away from the second part 1201, and the first flat part 1203 can be provided with the first clamping part 121. Specifically, as known from the foregoing, the first clamping part 121 is two, one of which is arranged on the first part 1200, and the other is arranged on the first flat part 1203, and the positions of the two first clamping parts 121 on the first part 1200 and the first flat part 1203 should correspond to each other, so that the two first clamping parts 121 can be engaged at the same height in the first direction X when engaged on the two opposite sides of the tooth-shaped groove 101.

[0074] Similarly, in order to realize the positioning and connection of the first clamping part 121 on the first flat part 1203, the first clamping part 121 can also be fixed on the first flat part 1203 by screwing, buckling or gluing, and in order to effectively position, a second positioning part (not shown) can also be arranged on the first flat part 1203, which can also be a positioning groove, so that the first clamping part 121 can be at least partially embedded in the second positioning part.

[0075] Further, the first protruding part 1202 can be a cylindrical protrusion, which is slidably connected to the second part 1201, so as to drive the first flat part 1203 and the first clamping part 121 on the first flat part 1203 away from or close to the first fixed part 120b and the first clamping part 121 on the first fixed part 120b. Specifically, in order to guide the sliding connection of the first protruding part 1202 relative to the first fixed part 120b, a first guide column 1204 can be arranged on the first fixed part 120b, and the first protruding part 1202 is provided with a first guide hole 1202a corresponding to the first guide column 1204, which is slidably connected to the first guide column 1204, so that the first protruding part 1202 can slide relative to the first fixed part 120b in the first direction X. By using the cooperation and connection of the first guide column 1204 and the first guide hole 1202a, the sliding of the first protruding part 1202 and the first flat part 1203 relative to the first fixed part 120b can be guided, so as to prevent the first protruding part 1202 and the first flat part 1203 from being deviated during sliding.

[0076] Further, in order to effectively fix the first guide column 1204 and prevent the first protruding part 1202 and the first flat plate part 1203 from being separated from the second part 1201 of the first fixing part 120b during the sliding away from the first fixing part 120b, one end of the first guide column 1204 can be fixed to the second part 1201 of the first fixing part 120b, and the other end of the first guide column 1204 can extend out of the first protruding part 1202 and the first flat plate part 1203 along the first guide hole 1202a of the first protruding part 1202 and the first flat plate part 1203. At this time, the first connecting piece 120 further comprises a first cover plate 120d fixedly connected to the other end of the first guide column 1204, so that the first cover plate 120d can limit the sliding position of the first protruding part 1202 and the first flat plate part 1203 relative to the second part 1201 of the first fixing part 120b and prevent the first protruding part 1202 and the first flat plate part 1203 from being separated from the second part 1201 of the first fixing part 120b. Of course, it can be understood that in other embodiments, the first cover plate 120d can not be provided, but a component such as a nut or a ring can be directly provided on the other end of the first guide column 1204, as long as the sliding position of the first protruding part 1202 and the first flat plate part 1203 can be limited, and the present embodiment does not make specific limitations in this regard.

[0077] For example, the first guide post 1204 can be a stepped post, which can include a first post body 1204a and a second post body 1204b connected to each other. One end of the first post body 1204a can be fixed on the second part 1201 of the first fixed part 120b by a first plug 1205 to prevent the first post body 1204a from being separated from the second part 1201 of the first fixed part 120b. The second post body 1204b can be connected to the other end of the first post body 1204a, and the connection between the second post body 1204b and the first post body 1204a can be located just at the connection between the first raised part 1202 and the first flat part 1203. The connection between the second post body 1204b and the first post body 1204a can be connected at the connection between the first raised part 1202 and the first flat part 1203 by a second plug 1206, and the other end of the second post body 1204b can be fixed on the first cover plate 120d by a screw. Of course, in other embodiments, the first guide post 1204 can also be a stepped post, but can also be a post with equal outer diameters. As long as the first guide post 1204 can be connected to the first fixed part 120b, the first raised part 1202, the first flat part 1203 and the first cover plate 120d, it can guide the sliding connection of the first raised part 1202 and the first flat part 1203, and can also limit the sliding distance of the first raised part 1202 and the first flat part 1203 relative to the first fixed part 120b. The specific structure of the first guide post 1204 in the present embodiment is not limited.

[0078] In some embodiments, in order to provide a reset after the first protruding portion 1202 and the first flat plate portion 1203 slide away from the first fixed portion 120b, the first clamping assembly 12a further comprises a first elastic member 120e, which is located in the first guide hole 1202a and connected to the first guide column 1204, for providing a force for resetting the sliding of the first protruding portion 1202 relative to the first fixed portion 120b. Specifically, the first elastic member 120e can be a spring, a spring piece or the like. Taking the first elastic member 120e as a spring for example, the first elastic member 120e is sleeved on the outer periphery of the first column body 1204a of the first guide column 1204, and the two ends of the first elastic member 120e are connected to the first plug 1205 and the second plug 1206 respectively. In actual operation, when the operator needs to adjust the meshing position of the two first clamping members 121 relative to the tooth-shaped groove 101, the first protruding portion 1202 can be pulled to drive the first flat plate portion 1203 to slide away from the first fixed portion 120b along the first direction X, so that the first clamping members 121 on the first flat plate portion 1203 are away from the first clamping members 121 on the first fixed portion 120b. At this time, the first clamping members 121 on the first flat plate portion 1203 are no longer meshed in the tooth-shaped groove 101, and the space of the first connecting space 120a is increased. At this time, the operator can adjust the meshing position of the first clamping members 121 on the first fixed portion 120b and the first clamping members 121 on the first flat plate portion 1203 relative to the tooth-shaped groove 101. At this time, the first clamping members 121 no longer clamp the first positioning member 110. Thus, the first positioning member 110 and the movable part 11 can slide relative to the mounting cavity 100 along the second direction Y to adjust the length of the movable part 11 extending out of the first opening 100a of the mounting cavity 100. When the adjustment is completed, the operator can release the first protruding portion 1202. At this time, under the elastic force of the first elastic member 120e, the first protruding portion 1202 and the first flat plate portion 1203 slide back relative to the first fixed portion 120b under the elastic force of the first elastic member 120e, so that the first clamping members 121 on the first flat plate portion 1203 are meshed in the tooth-shaped groove 101 again.

[0079] Correspondingly, considering that the structure of the second clamping assembly 12b is completely same as that of the first clamping assembly 12a, i.e., the structure of the second connecting member 122 and the second elastic member is completely same as that of the first connecting member 120 and the first elastic member 120e, and the way of adjusting the meshing position of the second connecting member 122 relative to the tooth-shaped groove 101 is also completely same as that of the first connecting member 120, therefore, for the structure of the second connecting member 122 and the second elastic member, please refer to the above description of the structure of the first connecting member 120 and the first elastic member 120e, which will not be repeated here.

[0080] In some embodiments, the first clamping member 121 and the second clamping member 123 can be block-shaped structures, the first clamping member 121 is provided with a first tooth-shaped portion 121a and a first positioning groove 121b, the second clamping member 123 is provided with a second tooth-shaped portion 123a and a second positioning groove 123b, the first tooth-shaped portion 121a and the second tooth-shaped portion 123a are engagedly connected to the tooth-shaped groove 101, the second positioning groove 123b is correspondingly arranged with the first positioning groove 121b and encloses a positioning space 124, and the first positioning member 110 can be connected to the positioning space 124. Specifically, the first clamping member 121 is approximately circular block-shaped, the first tooth-shaped portion 121a is arranged on the outer circumferential surface of the first clamping member 121, and the first positioning groove 121b is also arranged on the outer circumferential surface of the first clamping member 121 and is arranged in a spaced manner with the first tooth-shaped portion 121a. By arranging the first tooth-shaped portion 121a and the first positioning groove 121b on the outer circumferential surface of the first clamping member 121 and arranging the second tooth-shaped portion 123a and the second positioning groove 123b on the outer circumferential surface of the second clamping member 123, the engagement of the first tooth-shaped portion 121a and the second tooth-shaped portion 123a with the tooth-shaped groove 101 is achieved, and the first positioning groove 121b and the second positioning groove 123b can also be enclosed to form the positioning space 124, thereby facilitating the connection with the first positioning member 110. As can be seen, by using the method of the present application, the first clamping assembly 12a and the second clamping assembly 12b are connected to the first positioning member 110 in a sleeved clamping manner on the outer periphery of the first positioning member 110. This method not only makes the clamping connection of the first clamping assembly 12a and the second clamping assembly 12b to the first positioning member 110 more reliable, but also improves the disassembly convenience of the first clamping assembly 12a, the second clamping assembly 12b and the first positioning member 110 when disassembling.

[0081] Further, as known from the foregoing, the first positioning member 110 is cylindrical, and the first positioning groove 121b and the second positioning groove 123b can be semicircular grooves, so that the positioning space 124 enclosed by the first positioning groove 121b and the second positioning groove 123b is approximately circular to surround the outer periphery of the first positioning member 110. It can be understood that in other embodiments, the shapes of the first positioning groove 121b and the second positioning groove 123b can also be adjusted according to the shape of the first positioning member 110, for example, to be square grooves or grooves of other shapes.

[0082] Further, the first positioning groove 121b can be two, which can be symmetrically arranged relative to the center of the first clamping piece 121, and the first tooth-shaped part 121a is located between the two first positioning grooves 121b. Correspondingly, the second clamping piece 123 is also approximately circular block, and the second tooth-shaped part 123a is arranged on the outer circumferential surface of the second clamping piece 123, and the second positioning groove 123b is also arranged on the outer circumferential surface of the second clamping piece 123 and is arranged in a spaced manner with the second tooth-shaped part 123a. Specifically, the second positioning groove 123b can be two, which can be symmetrically arranged relative to the center of the second clamping piece 123, and the second tooth-shaped part 123a is located between the two second positioning grooves 123b. By arranging two first positioning grooves 121b and two second positioning grooves 123b on the first clamping piece 121 and the second clamping piece 123 respectively, the first clamping piece 121 and the second clamping piece 123 have the same structure, and no matter whether the first clamping piece 121 is arranged above the second clamping piece 123 or below the second clamping piece 123, the first positioning groove 121b can cooperate with the second positioning groove 123b to form a positioning space 124, thereby realizing the connection of the first positioning piece 110. In this way, the first clamping piece 121 and the second clamping piece 123 can be formed as components with the same structure, which facilitates the machining of the first clamping piece 121 and the second clamping piece 123, and further makes the machining of the angle adjusting device 1 simpler and the assembly more convenient. It can be understood that in other embodiments, only one first positioning groove 121b and one second positioning groove 123b can be arranged on the first clamping piece 121 and the second clamping piece 123.

[0083] The following will explain in detail how the present embodiment adjusts the angle between two adjacent loudspeaker bodies 20.

[0084] Please refer to Figure 7With the two adjacent loudspeaker bodies 20 as a first loudspeaker body 20 and a second loudspeaker body 20, the second loudspeaker body 20 is arranged above the first loudspeaker body 20 along the second direction Y. In the initial state, i.e., the first loudspeaker body 20 has a certain length of the movable part 11 extending out of the mounting cavity 100, at this time, the first clamping assembly 12a and the second clamping assembly 12b on the first loudspeaker body 20 are clamped and connected to the first positioning member 110, and are engaged and connected to the tooth-shaped groove 101. When the distance needs to be adjusted, the operator can pull the first clamping assembly 12a or the second clamping assembly 12b through the angle mark on the first fixed part 120b, so that the first clamping member 121 or the second clamping member 123 on the first clamping assembly 12a and the second clamping assembly 12b can be engaged to the position of the target angle mark 105 relative to the tooth-shaped groove 101, at this time, since the first clamping member 121 or the second clamping member 123 is no longer connected to the first positioning member 110, the first positioning member 110 and the movable part 11 slide relative to the mounting cavity 100 until the first positioning member 110 slides to the position of cooperating with the first clamping member or the second clamping member again, and the length of the movable part 11 extending out of the mounting cavity 100 is completed. Since the first end 111 of the movable part 11 on the first loudspeaker body 20 is rotatably connected in the second opening 100b of the mounting cavity 100 of the second loudspeaker body 20, the distance of the first end 111 of the movable part 11 on the first loudspeaker body 20 extending into the mounting cavity 100 of the second loudspeaker body 20 is fixed, at this time, the first end 111 of the movable part 11 on the first loudspeaker body 20 is rotatably connected with the mounting cavity 100 on the second loudspeaker body 20, so that the angle between the first loudspeaker body 20 and the second loudspeaker body 20 can be adjusted.

[0085] It should be noted that when the distance needs to be adjusted, for example, the first clamping assembly 12a is pulled to engage the target position of the tooth-shaped groove 101, the operator can pull the first clamping assembly 12a through the angle mark 105 on the first fixed part 120b, so that the first clamping part 121 on the first clamping assembly 12a is engaged to the target angle mark 105 position relative to the tooth-shaped groove 101. At this time, the first clamping part 121 is no longer connected to the first positioning part 110, and the second clamping part 123 is connected to the first positioning part 110. By pulling the second clamping assembly 12b to drive the first positioning part 110 and the movable part 11 to slide relative to the mounting cavity 100, until the second clamping assembly 12b is engaged to the target angle mark 105 position relative to the tooth-shaped groove 101, the first clamping part 121 and the second clamping part 123 re-enclose the positioning space 124, so that the first positioning part 110 is connected to the first clamping part 121 and the second clamping part 123 again, and the length of the movable part 11 extending out of the mounting cavity 100 is completed.

[0086] It can be seen that the angle adjusting device 1 of the present application can achieve simple and fast adjustment of the angle between the two adjacent loudspeaker bodies 20. Since the angle adjusting device 1 is achieved by the engagement connection of the tooth-shaped groove 101 and the first clamping part 121 and the second clamping part 123, the angle adjustment span is smaller, which can meet the demand of precise angle adjustment between loudspeakers, improve the in-situ sound pressure uniformity, and further improve the sound effect.

[0087] Please refer to Figures 7 to 10 The second aspect of the present application discloses a loudspeaker angle adjusting system 2, which comprises a plurality of linearly arrayed loudspeaker bodies 20 and a plurality of angle adjusting devices 1 as described in the first aspect above. Each loudspeaker body 20 comprises opposite first and second sides 20a and 20b, and the first sides 20a of adjacent two loudspeaker bodies 20 are rotatably connected. The second side 20b of each loudspeaker body 20 is provided with the angle adjusting device 1 described in the first aspect above.

[0088] Specifically, when the plurality of loudspeaker bodies 20 on the loudspeaker angle adjusting system 2 are linearly connected, they are mainly arranged in sequence along the height direction, so that the first end 111 of the movable part 11 on each loudspeaker body 20 can extend into the mounting cavity 100 of another loudspeaker body 20 located above and be rotatably connected thereto.

[0089] It can be understood that, due to the fact that each speaker body 20 is substantially trapezoidal, i.e. the height of each speaker body 20 gradually increases from the second side 20b to the first side 20a, when the plurality of speaker bodies 20 are connected in a line, the adjacent two speaker bodies 20 inherently have a certain angle therebetween, and the angle adjusting device of the present application is mainly used to further adjust the angle of the adjacent two speaker bodies 20 within this angle range.

[0090] In some embodiments, the speaker angle adjusting system 2 can further comprise a plurality of rotating devices 21, each rotating device 21 being arranged on a corresponding speaker body 20. The rotating device 21 is used to achieve the rotatable connection of the first side 20a of the adjacent two speaker bodies 20. Specifically, the rotating device 21 comprises a fixed structure 210 and a sliding component 211, the fixed structure 210 being arranged on the first side 20a of the speaker body 20, the fixed structure 210 being provided with a sliding cavity 2103, and the sliding component 211 being slidably connected to the sliding cavity 2103. In the adjacent two speaker bodies 20, the sliding component 211 of one speaker body 20 can be slid to partially outside the sliding cavity 2103 to be rotatably connected with the fixed structure 210 of the other speaker body 20, so as to achieve the rotatable connection of the first side 20a of the adjacent two speaker bodies 20. By using the rotating device 21 comprising the fixed structure 210 and the sliding component 211, the sliding component 211 can be slidably connected to the sliding cavity 2103 of the fixed structure 210, so as to adjust the length of the sliding component 211 extending out of the sliding cavity 2103 according to different heights or types of speaker bodies 20.

[0091] Further, the fixing structure 210 comprises a first fixing plate 2100, a support plate 2101 and a second fixing plate 2102, the first fixing plate 2100 is fixedly arranged on the first side 20a of the loudspeaker body 20, the support plate 2101 is arranged on the side of the first fixing plate 2100 away from the first side 20a of the loudspeaker body 20, and the second fixing plate 2102 is fixed on the support plate 2101, so that the support plate 2101 is arranged to form the sliding cavity 2103 between the second fixing plate 2102 and the first fixing plate 2100. Specifically, the first fixing plate 2100 can be fixed on the first side 20a of the loudspeaker body 20 by screws, buckles or the like for easy installation. The first fixing plate 2100 can be an elongated plate with its length direction along the height direction of the loudspeaker body 20, and the support plate 2101 and the second fixing plate 2102 are also elongated plates which can also extend along the height direction of the loudspeaker body 20. The thickness of the support plate 2101 is greater than the thickness of the first fixing plate 2100 and the second fixing plate 2102, and the length of the support plate 2101 is less than the length of the first fixing plate 2100 and the second fixing plate 2102, so that when the support plate 2101 is fixed between the first fixing plate 2100 and the second fixing plate 2102, the sliding cavity 2103 is formed between the first fixing plate 2100 and the second fixing plate 2102. It can be seen that the size of the sliding cavity 2103 mainly depends on the size of the support plate 2101, such as the thickness and the length.

[0092] By using the fixing structure 210 comprising the first fixing plate 2100, the support plate 2101 and the second fixing plate 2102, and using the support plate 2101 to fix the first fixing plate 2100 and the second fixing plate 2102 to form the sliding cavity 2103, the forming method of the sliding cavity 2103 is simpler, which replaces the block structure or the frame structure to form the sliding cavity 2103, and the overall structure of the fixing structure 210 can be made thinner, effectively reducing the overall weight of the loudspeaker angle adjusting system 2.

[0093] Further, the sliding part 211 is also an elongated plate, and the end faces of the sliding part 211 are both arc faces, so that the arc faces can be arranged on the end faces of the support plate 2101 to cooperate with the sliding part 211, so that the support plate 2101 can effectively support and limit the sliding part 211.

[0094] In some embodiments, in order to facilitate the adjustment of the sliding position of the sliding component 211 in the sliding cavity 2103, a sliding groove 2102a can be provided on the second fixed plate 2102, which is communicated with the sliding cavity 2103. The sliding component 211 can be provided with a first alignment hole 2110 and a second alignment hole 2111 which are sequentially and spaced apart along the sliding direction of the sliding component 211. The first alignment hole 2110 can be used to connect a fastening screw 2112, and the fastening screw 2112 is located in the sliding groove 2102a to guide the sliding of the sliding component 211 in the sliding cavity 2103. When the sliding component 211 is slid into position, that is, the sliding component 211 has been slid to be partially located outside the sliding cavity 2103 and connected with another speaker main body 20, the sliding component 211 can be fixed by a pin 2113 in the second alignment hole 2111, so that the position of the sliding component 211 relative to the sliding cavity 2103 is fixed.

[0095] Further, as known from the foregoing, the sliding component 211 on each speaker main body 20 can be slid to be partially located outside the sliding cavity 2103 and rotationally connected with another speaker main body 20. Therefore, the second fixed plate 2102 can further be provided with a first rotationally connecting hole 2102b, and the sliding component 211 can further be provided with a second rotationally connecting hole 2114. The portion of the sliding component 211 provided with the second rotationally connecting hole 2114 is located outside the sliding cavity 2103 and extends into the sliding cavity 2103 of the adjacent another speaker main body 20, corresponding to and communicated with the first rotationally connecting hole 2102b. At this time, the sliding component 211 and the second fixed plate 2102 of the another speaker main body 20 can be rotationally connected by a rotating pin 2115 passing through the first rotationally connecting hole 2102b and the second rotationally connecting hole 2114. For example, taking two adjacent speaker main bodies 20 as a first speaker main body 20 and a second speaker main body 20, the portion of the sliding component 211 on the first speaker main body 20 provided with the second rotationally connecting hole 2114 is slid and extends outside the sliding cavity 2103 and into the sliding cavity 2103 of the second speaker main body 20, corresponding to and communicated with the first rotationally connecting hole 2102b on the second fixed plate 2102 of the second speaker main body 20. Then, the first speaker main body 20 and the second speaker main body 20 are rotationally connected by the rotating pin 2115 passing through the first rotationally connecting hole 2102b and the second rotationally connecting hole 2114.

[0096] This rotationally connecting manner can make the rotationally connecting manner of the two adjacent speaker main bodies 20 simpler, and can also hide the rotationally connecting position of the two adjacent speaker main bodies 20, so that the structure of the speaker angle adjustment system 2 is more simple and compact.

[0097] It can be understood that in other embodiments, the rotational connection between the two adjacent loudspeaker bodies 20 can also be achieved in other ways, for example, by a hinged manner, and the present embodiment does not make specific limitations thereto.

[0098] Please refer to Figure 11 and Figure 12 It can be understood that in some embodiments, considering that the loudspeaker angle adjustment system 2 is mainly suspended in a performance scene, for example, suspended above the stage, therefore, the loudspeaker angle adjustment system 2 further comprises a suspension bracket, along the linear array direction of the plurality of loudspeaker bodies 20, the uppermost loudspeaker body 20 is a first loudspeaker body 20, and the lowermost loudspeaker body 20 is a second loudspeaker body 20, the first loudspeaker body 20 and / or the second loudspeaker body 20 can be connected with the above-mentioned suspension bracket, and the suspension bracket can be used to be connected with, for example, a rigging, so as to realize the lifting of the loudspeaker angle adjustment system 2 to a certain height to meet the height installation requirements of different use scenes.

[0099] Further, the first loudspeaker body 20 can be connected with the above-mentioned suspension bracket, and at this time, the suspension bracket is connected to the uppermost loudspeaker body 20, or the second loudspeaker body 20 can be connected with the above-mentioned suspension bracket, that is, at this time, the suspension bracket is connected to the lowermost loudspeaker body 20. Alternatively, the first loudspeaker body 20 and the second loudspeaker body 20 can be connected with the suspension bracket, so as to improve the suspension safety and reliability of the loudspeaker angle adjustment system 2.

[0100] Specifically, when the first loudspeaker body 20 is connected with the suspension bracket, the suspension bracket can be an upper hanger 22. The upper hanger 22 is a frame structure, comprising two first side plates 220 and two first support columns 221, the two first side plates 220 are arranged at intervals, and the two first support columns 221 are connected between the two first side plates 220, so that the two first support columns 221 and the two first side plates 220 are connected to form a square frame with a shape substantially adapted to the first loudspeaker body 20. The two first side plates 220 can be connected to the first loudspeaker body 20, and specifically can be connected to the sliding part 211 on the first loudspeaker body 20, so as to realize the connection between the upper hanger 22 and the first loudspeaker body 20. Specifically, in the actual connection, a first connecting hole 220a can be arranged on the first side plate 220, as mentioned above, the sliding part 211 is provided with a second rotational connecting hole 2114, since the first loudspeaker body 20 is located at the uppermost position, the sliding part 211 is no longer connected with other loudspeaker bodies 20, therefore, the second rotational connecting hole 2114 can be used to be fixed with the first connecting hole 220a through a fixed pin 233, so as to realize the connection between the first loudspeaker body 20 and the upper hanger 22.

[0101] Further, the upper hanger 22 further comprises a first hanger plate 222 connected to the two first support columns 221 and arranged in parallel with the first side plate 220, and two ends of the first hanger plate 222 are respectively provided with a first lifting ring 222a for connecting with a cable, so that the first lifting ring 222a is connected by the cable to drive the upper hanger 22 and the loudspeaker body 20 to rise as a whole. The first hanger plate 222 can be provided with a second connecting hole 222b, as known from the foregoing, the movable part 11 is provided with a first rotating hole 111a, and therefore, the second connecting hole 222b can be used to be fixed with the first rotating hole 111a through the fixed pin 233, so as to further strengthen the stability of the connection with the upper hanger 22. It can be seen that, by using the mode of the embodiment, the connection mode of the upper hanger 22 and the first loudspeaker body 20 is simpler, and no additional connection structure is needed.

[0102] When the suspension bracket is connected to the second loudspeaker body 20, the suspension bracket can be a lower hanger 23, and the lower hanger 23 can comprise two second side plates 230 arranged in parallel and spaced apart, and three second support columns 231 connected between the two second side plates 230 and arranged in spaced apart.

[0103] Further, the lower hanger 23 further comprises a second hanger plate 232 connected to the second support column 231 and arranged in parallel with the second side plate 230, and the second hanger plate 232 is provided with a second lifting ring 232a for connecting with a cable, so that the second lifting ring 232a is connected by the cable to drive the lower hanger 23 and the loudspeaker body 20 to rise as a whole. Specifically, when the lower hanger 23 is connected to the second loudspeaker body 20, it is mainly connected to the second loudspeaker body 20 through the second hanger plate 232 and the second side plate 230. In actual connection, the second side plate 230 can be provided with a first connecting plate 230a, the first connecting plate 230a can be provided with a third connecting hole 2300, the third connecting hole 2300 is connected with the first rotating connecting hole 2102b on the second fixed plate 2102 through the rotating pin 2115, the second hanger plate 232 can be provided with a second connecting plate 232b, the second connecting plate 232b can be provided with a fourth connecting hole 2320, and the second connecting plate 232b can extend into the second opening 100b of the mounting cavity 100 of the second loudspeaker body 20, so that the second connecting hole 222b can be connected with the second rotating hole 100c on the mounting cavity 100 through the fixed pin 233, to realize the connection between the lower hanger 23 and the second loudspeaker body 20.

[0104] The following will describe the angle adjustment mode of the loudspeaker angle adjustment system 2 using the embodiment.

[0105] The loudspeaker angle adjustment system 2 of the present application mainly realizes angle adjustment through the tooth-shaped groove 101 and the clamping structure 12, and can be suspended through the upper hanger 22 and / or the lower hanger 23, so the loudspeaker angle adjustment system 2 of the present application can have two adjustment modes, i.e. gravity type adjustment mode and compression type adjustment mode, which will be described below.

[0106] Gravity type adjustment mode:

[0107] 1) First, connect the plurality of loudspeaker bodies 20 in linear array mode in turn, and place the loudspeaker bodies 20 on the ground, and the adjacent two loudspeaker bodies 20 are in close contact state; take three of the plurality of loudspeaker bodies 20 as an example, the uppermost is the first loudspeaker body 20, the middle is the middle loudspeaker body 20, and the bottom is the second loudspeaker body 20.

[0108] 2) Then, suspend the upper hanger 22 above the uppermost loudspeaker body 20 (i.e. the first loudspeaker body 20), and connect the upper hanger 22 with the first loudspeaker body 20;

[0109] 3) Adjust the angle of the middle loudspeaker body 20 and the first loudspeaker body 20, and adjust the angle between the second loudspeaker and the middle loudspeaker, open the first clamping assembly 12a on the middle loudspeaker body 20 and the second loudspeaker, i.e. make the first movable part 120c move relative to the first fixed part 120b, according to the angle mark 105 on the fixed support 10, determine the position of the angle mark 105 corresponding to the tooth-shaped groove 101 (i.e. the target angle position), and then release the first movable part 120c, so that the first movable part 120c resets, at this time, the first clamping piece 121 engages with the tooth-shaped groove 101, but at this time, the first clamping piece 121 on the middle loudspeaker body 20 has no clamping effect on the first positioning piece 110 thereon, and similarly, the first clamping piece 121 on the second loudspeaker body 20 has no clamping effect on the first positioning piece 110 thereon;

[0110] 4) Drive the upper hanger 22 to lift the plurality of loudspeaker bodies 20 through the rigging, due to the effect of gravity, the second side 20b of the loudspeaker body 20 except the first loudspeaker (i.e. the middle loudspeaker body 20 and the second loudspeaker body 20) moves downward due to the effect of gravity, so that the first positioning piece 110 thereon can move upward relative to the tooth-shaped groove 101, until the first positioning piece 110 moves upward to connect with the first clamping assembly 12a, at this time, the angle between the adjacent two loudspeaker bodies 20 is adjusted to the required angle;

[0111] 6) open the second clamping assembly 12b on the middle speaker body 20 and the second speaker body 20, and put it into the position corresponding to the tooth-shaped groove 101 close to the first clamping assembly 12a, so that the second clamping assembly 12b and the first clamping assembly 12a jointly define the position of the first positioning member 110, so as to keep the angle between the adjacent two speaker bodies 20 fixed.

[0112] It can be seen that the gravity type adjustment mode mainly utilizes the gravity effect, cooperates with the above-mentioned clamping structure 12 and the tooth-shaped groove 101 to realize angle adjustment.

[0113] Compression type adjustment mode:

[0114] 1) First, connect a plurality of speaker bodies 20 in a linear array, and place the speaker bodies 20 on the ground, and the adjacent two speaker bodies 20 are in close contact; take three of the plurality of speaker bodies 20 as an example, the uppermost is the first speaker body 20, the middle is the middle speaker body 20, and the bottom is the second speaker body 20;

[0115] 2) Then, the upper hanger 22 is suspended above the first speaker body 20 and connected with the first speaker body 20;

[0116] 3) Open the first clamping assembly 12a on the middle speaker body 20 and the second speaker body 20 respectively, and put it into the uppermost position of the tooth-shaped groove 101 (for example, it can be the position corresponding to the angle mark 105 0°) along the height direction of the speaker body 20, so that the first clamping assembly 12a engages with the uppermost of the tooth-shaped groove 101;

[0117] 4) Lift the upper hanger 22 by the rigging to lift the plurality of speaker bodies 20, due to the gravity effect, the second side 20b of the remaining speaker bodies 20 (i.e. the middle speaker body 20 and the second speaker body 20) except the first speaker body 20 all move downward due to the gravity effect, so that the first positioning member 110 on them can move upward relative to the tooth-shaped groove 101, until the first positioning member 110 moves upward to be connected with the first clamping assembly 12a;

[0118] 6) Open the second clamping assembly 12b on the middle speaker body 20 and the second speaker body 20, and put it into the position corresponding to the tooth-shaped groove 101 at the required angle, for example, it can be the position corresponding to the angle mark 105 3.5°;

[0119] 7) connecting the lower hanger 23 with the second speaker body, and connecting the lower hanger 23 through rigging to drive the second speaker body 20 to move upward, at this time, the first positioning member 110 on the second speaker body 20 and the intermediate speaker body 20 moves downward relative to the tooth-shaped slot 101 until the first positioning member 110 abuts against the second clamping assembly 12b, so that the angle between the speaker bodies 20 is adjusted to the required angle;

[0120] 8) opening the second clamping assembly 12b on the intermediate speaker body 20 and the second speaker body 20, and placing it in the position corresponding to the tooth-shaped slot 101 close to the first clamping assembly 12a, so that the second clamping assembly 12b and the first clamping assembly 12a jointly define the position of the first positioning member 110, so that the angle between the two adjacent speaker bodies 20 is kept fixed.

[0121] Therefore, the speaker angle adjustment system 2 of the present application can realize the adjustment mode of the pre-determined angle between the multiple speaker bodies 20, the adjustment angle has smaller step, the angle adjustment precision is higher, and the adjustment process saves time and labor, and is convenient to operate.

[0122] In addition, the speaker angle adjustment system 2 of the present application can adopt the gravity type adjustment mode or the compression type adjustment mode, the adjustment mode is more flexible, and the application range of the speaker angle adjustment system 2 can be expanded.

[0123] The above describes in detail the angle adjustment device and the speaker angle adjustment system disclosed in the embodiments of the present application, and the principles and implementation modes of the present application are described by applying specific examples; the above embodiment is only used to help understand the angle adjustment device and the speaker angle adjustment system of the present application and the core idea thereof; at the same time, for the general technical personnel in the field, according to the idea of the present application, the specific implementation mode and the application range will be changed, and according to the above, the content of the specification should not be understood as the limitation of the present application.
