[0042] This application relates to a sound reinforcement device, which includes a speaker unit 1000 and a sound reinforcement column 2000, wherein the sound reinforcement column 2000 is detachably disposed on the speaker unit 1000.

[0043] Understandably, the sound reinforcement column 2000 and the speaker unit 1000 can be detached to allow for modular and rapid deployment of the sound reinforcement equipment.

[0044] It should be noted that the sound reinforcement equipment is versatile and can adapt to at least the following usage scenarios: 1. The sound reinforcement column 2000 is fixed to the speaker unit 1000, and the sound reinforcement equipment is hoisted. 2.

[0045] Other components and operations of the sound reinforcement equipment have been described in the relevant art for those skilled in the art, and will not be described in detail here. The structure of the speaker device 1000 and the sound reinforcement column 2000 will be described below.

[0046] This application relates to a speaker device 1000, which includes a base 1100 and a first speaker 1200. The first speaker 1200 is detachably mounted on the base 1100 via at least one inserted connecting rail 1300. Specifically, the first speaker 1200 is mounted on the base 1100, and the connecting rail 1300 is inserted between the first speaker 1200 and the base 1100, and the connecting rail 1300 respectively engages with the first speaker 1200 and the base 1100 to connect the first speaker 1200 and the base 1100.

[0047] It should be noted that the first speaker, 1200, is a line array speaker designed for mid-high frequencies.

[0048] A first slot 1400 is provided on the surface of the base 1100 facing the first speaker 1200, and a first slot 1400 is provided on the surface of the first speaker 1200 facing the base 1100. Specifically, a first slot 1400 is provided on the upper surface of the base 1100 and a first slot 1400 is provided on the lower bottom surface of the first speaker 1200. The first speaker 1200 is placed on the base 1100 and the positions of the first slots 1400 of the two are corresponding, so that the corresponding two first slots 1400 are combined to form a slot for the connecting rail 1300 to be inserted.

[0049] Understandably, the connecting rail 1300 is designed as a long rod, and it is inserted into both first slots 1400. The connecting rail 1300 engages with the inner walls of the two first slots 1400 respectively, allowing the first speaker 1200 to be mounted on the base 1100. In this configuration, the first speaker 1200 is detachably mounted on the base 1100 via the connecting rail 1300, enabling quick assembly and disassembly between the first speaker 1200 and the base 1100, thus facilitating modular and rapid assembly of the first speaker 1200 and the base 1100.

[0050] In some embodiments, the first slot 1400 includes a snap-fit ​​groove 1401 and a through groove 1402 extending along the length of the first slot 1400. The through groove 1402 communicates with the snap-fit ​​groove 1401. The through groove 1402 is located outside the first slot 1400, and the snap-fit ​​groove 1401 is located inside the first slot 1400. The through groove 1402 connects the inside and outside of the first slot 1400. The through groove 1402 is smaller than the width of the snap-fit ​​groove 1401, and the first slot 1400 is formed with a narrow opening and a wide interior. It can be understood that the slot cross-section formed by the combination of the first slot 1400 of the base 1100 and the first speaker 1200 is a shape that is wide at both ends and narrow in the middle.

[0051] Furthermore, the connecting rail 1300 includes a web and flanges, with flanges arranged at both ends of the web at intervals along the width direction. Specifically, the cross-section of the connecting rail 1300 is formed into a shape that is wider at both ends and narrower in the middle. In some examples, the connecting rail 1300 adopts an I-beam design.

[0052] Understandably, with the direction in which the connecting rail 1300 is inserted into the first slot 1400 as the forward direction, when the connecting rail 1300 is inserted forward between the first speaker 1200 and the base 1100, the connecting rail 1300 is simultaneously inserted into both first slots 1400. Two wing plates are respectively inserted into the engaging slots 1401 of the two first slots 1400. The width of the wing plates is greater than the width of the through slot 1402, so that the connecting rail 1300 engages with the inner wall of the first slot 1400 through the wing plates. Under the engaging action of the connecting rail 1300, the first speaker 1200 remains connected to the base 1100, and the first speaker 1200 cannot move upwards or left or right relative to the base 1100.

[0053] It should be noted that at least one first slot 1400 is provided on both the first speaker 1200 and the base 1100, and correspondingly, at least one connecting rail 1300 is provided. In some examples, two first slots 1400 are provided on both the first speaker 1200 and the base 1100, and the two first slots 1400 are parallel and spaced apart, and correspondingly, two connecting rails 1300 are provided.

[0054] In some embodiments, a stop block 1301 is provided at one end of the connecting rail 1300 for insertion into the first slot 1400. The stop block 1301 is rotatable along a central axis parallel to the length direction of the connecting rail 1300 and abuts against the end of the first slot 1400. It is understood that the stop block 1301 is located at the front end of the connecting rail 1300.

[0055] The anti-reverse block 1301 has the same cross-sectional shape as the connecting rail 1300 so that the front end of the connecting rail 1300 can be inserted into the first slot 1400. The end of the connecting rail 1300 where the anti-reverse block 1301 is located extends out of the first slot 1400. By rotating the anti-reverse block 1301 by a set angle, the I-shape of the anti-reverse block 1301 is offset from the I-shape of the connecting rail 1300, so that the anti-reverse block 1301 can abut against the end of the first slot 1400, thereby achieving the anti-reverse function of the connecting rail 1300 in the first slot 1400.

[0056] Furthermore, the anti-reverse block 1301 is elastically connected to the connecting rail 1300 so that the anti-reverse block 1301 can be pulled forward, thereby facilitating the rotation of the anti-reverse block 1301. Under the elastic action, the anti-reverse block 1301 can move backward and abut against the end of the first slot 1400, thereby preventing the connecting rail 1300 from moving backward.

[0057] Specifically, the front end of the connecting rail 1300 is provided with a connecting shaft for mounting the anti-reverse block 1301. The anti-reverse block 1301 is rotatably sleeved on the connecting shaft, and a compression spring is sleeved on the connecting shaft. The rear end of the compression spring applies a rearward force to the anti-reverse block 1301. When the anti-reverse block 1301 moves forward, the compression spring generates compressive elastic potential energy, so that the rotated anti-reverse block 1301 can move backward and abut against the end face of the first slot 1400, realizing the quick installation and anti-reverse of the connecting rail 1300.

[0058] In some examples, a stop 1302 is provided at the other end of the connecting rail 1300, which is used to abut against the end of the other end of the first slot 1400. Specifically, the stop 1302 is located at the rear end of the connecting rail 1300.

[0059] Understandably, the front end of the connecting rail 1300 abuts against the front end of the first slot 1400 with a stop block 1301, and the rear end of the connecting rail 1300 abuts against the rear end of the first slot 1400 with a stop block 1302, thereby fixing the connecting rail 1300 in the first slot 1400, enabling quick installation of the connecting rail 1300, preventing the connecting rail 1300 from separating from the first slot 1400, and improving the connection strength and stability between the first speaker 1200 and the base 1100.

[0060] In some embodiments, the base 1100 is provided with at least one extension arm 1101, which extends parallel to the surface of the base 1100. The extension arm 1101 can increase the actual contact area between the base 1100 and the bottom surface, thereby lowering the center of gravity of the speaker device 1000 or the sound reinforcement equipment and improving the stability of the speaker device 1000 or the sound reinforcement equipment.

[0061] Furthermore, one end of the extension arm 1101 is hinged to the base 1100, and the extension arm 1101 is rotatable along a central axis perpendicular to the surface of the base 1100. The extension arm 1101 can rotate to adjust its position relative to the base 1100, thereby adjusting the stability of the speaker assembly 1000 or the sound reinforcement equipment. On the other hand, the extension arm 1101 can rotate to achieve storage; when in use, the extension arm 1101 is rotated to the extended state, and when not in use, the extension arm 1101 is rotated to a position close to or against the edge of the base 1100.

[0062] In some examples, the extension arm 1101 is provided with feet for contact with the ground or stage. The feet are mounted on the extension arm 1101 with universal joints to accommodate uneven ground or stage.

[0063] It should be noted that the edge of the base 1100 is provided with a receiving notch 1102, the position of which corresponds to the position of the support leg on the extension arm 1101, and the number of receiving notches 1102 is the same as the number of support legs. When the extension arm 1101 rotates to a position where it is in contact with the edge of the base 1100, the support leg is located in the receiving notch 1102.

[0064] In some examples, the base 1100 is rectangular in shape, and there are four extension arms 1101. The four extension arms 1101 are located at the four corners of the base 1100, and the edges of the four sides of the base 1100 are provided with receiving notches 1102.

[0065] This application relates to a sound reinforcement column 2000, which includes a second speaker 2100 and a support frame 2200, with the second speaker 2100 disposed on the support frame 2200. Further, the support frame 2200 is detachably disposed on a first speaker 1200 to achieve a detachable connection between the sound reinforcement column 2000 and the speaker assembly 1000. Specifically, the support frame 2200 is located above the first speaker 1200.

[0066] Furthermore, the second speaker 2100 is detachably mounted on the support frame 2200, thereby achieving modular structure of the sound reinforcement column 2000. In use, the support frame 2200 is assembled to the first speaker 1200, and the second speaker 2100 is assembled to the support frame 2200, realizing modular assembly of the sound reinforcement equipment.

[0067] It should be noted that the first speaker, 1200, is configured as a subwoofer.

[0068] In some embodiments, the support frame 2200 includes a base plate 2201 and two support arms 2202, which are spaced apart along a first direction parallel to the length of the base plate 2201, and the first end of the support arm 2202 is connected to the base plate 2201. It is understood that the support frame 2200 is formed as a U-shaped frame.

[0069] The second speaker 2100 is mounted between the two support arms 2202 of the support frame 2200. Specifically, the two ends of the second speaker 2100 along the first direction are respectively located at the second ends of the two support arms 2202 away from the base plate 2201, and the second speaker 2100 is detachable from the support arms 2202 to achieve a detachable connection between the second speaker 2100 and the support frame 2200.

[0070] In some examples, the two ends of the second speaker 2100 along the first direction are detachably mounted on the second ends of the two support arms 2202 via hinge structures. The second speaker 2100 connected to the support arms 2202 can rotate along the center line of the first direction to adjust the direction of the sound waves of the second speaker 2100.

[0071] Specifically, a hinge structure is provided at the second end of the support arm 2202, and the hinge structure is detachable from the second speaker 2100 so that the second speaker 2100 can be detached from the support arm 2202.

[0072] In some examples, the hinge structure includes a mounting shaft 2203, to which the end of the second speaker 2100 is rotatably connected, and the end of the second speaker 2100 is detachably connected to the mounting shaft 2203. Further, the mounting shaft 2203 is pull-out movable at the second end of the support arm 2202 so that the second speaker 2100 is positioned between the two support arms 2202.

[0073] In some embodiments, the second end of the support arm 2202 is provided with a limiting groove extending along an arcuate trajectory, the limiting groove passing through the support arm 2202 along its thickness direction. The second speaker 2100 connected to the support arm 2202 is provided with a second locking member, the second locking member passing through the limiting groove and connected to the second speaker 2100, the second locking member being able to fix the second speaker 2100 and the support arm 2202 in a fixed connection.

[0074] It should be noted that the limiting groove is equipped with an angle scale to accurately control the rotation angle of the second speaker 2100 on the support frame 2200. The second locking component serves both as a locking and fixing element and as an indicator scale.

[0075] In some examples, the second locking member passes through the limiting groove and is threadedly connected to the second speaker 2100. The second locking member rotates to fix the second speaker 2100 connected to the support arm 2202. Specifically, the side wall of the second locking member has a shoulder for abutting against the side of the support arm 2202. Tightening the second locking member presses the shoulder against the support arm 2202, thereby achieving a fixed connection between the second speaker 2100 and the support arm 2202.

[0076] In some embodiments, at least two second speakers 2100 are provided, arranged in layers, with adjacent speakers 2100 interconnected. Further, one of the second speakers 2100 is detachably connected to the support frame 2200, and other second speakers 2100 can be connected to both its upper and lower sides. In this case, the hinged structure allows for adjustment of the overall vertical angle of the sound reinforcement column 2000, thereby enabling adjustment of the sound wave direction and coverage area of ​​the sound reinforcement equipment.

[0077] Furthermore, the two adjacent second speakers 2100 are detachably connected, and the two adjacent second speakers 2100 can rotate along a central axis parallel to the first direction to adjust the direction of the sound waves of the second speakers 2100.

[0078] In some examples, one of the upper and lower sides of the second speaker 2100 is provided with a mounting groove 2101, and the other side is provided with a hook 2102. The mounting groove 2101 and the hook 2102 both extend along the first direction in their length direction. When two adjacent layers of second speakers 2100 are connected to each other, the corresponding hooks 2102 are inserted into the mounting grooves 2101, thereby realizing modular assembly and rapid assembly of multiple second speakers 2100.

[0079] It should be noted that the assembly of the hooks 2102 and mounting slots 2101 between two adjacent second speaker boxes 2100 achieves a detachable connection between the two adjacent second speaker boxes 2100. On the other hand, the second speaker box 2100 can rotate up and down with the hooks 2102 as the rotation axis in the first direction, thereby enabling the two adjacent second speaker boxes 2100 to rotate and adjust their direction along the central axis parallel to the first direction. This allows the vertical angle of each second speaker box 2100 in the sound reinforcement column 2000 to be adjustable, and thus the sound wave direction and coverage of the sound reinforcement equipment to be adjustable.

[0080] Furthermore, the side of the second speaker 2100 is provided with a connecting rod 2103 and at least two positioning holes 2104. The connecting rod 2103 is hinged to the side of the second speaker 2100, and the side wall of the connecting rod 2103 is provided with a positioning post. After the two adjacent layers of second speakers 2100 rotate relative to each other, the positioning post of the connecting rod 2103 of one second speaker 2100 is inserted into the positioning hole 2104 of the other second speaker 2100 to fix the angle of the two adjacent layers of second speakers 2100.

[0081] In some examples, the second speaker 2100 includes an adjustable horn plate 2105 that can rotate along a vertical central axis to adjust the direction of the sound waves, thereby making the direction of the sound waves and the coverage area adjustable in the horizontal direction.

[0082] Based on the above description of the speaker device 1000 and the sound amplification column 2000, the following provides a supplementary description of the method by which the sound amplification column 2000 and the speaker device 1000 are detachably connected.

[0083] In some embodiments, one of the base plate 2201 and the first speaker 1200 is provided with a second slot 3100, and the other is provided with a guide rail 3200. The guide rail 3200 is inserted into the second slot 3100 and engages with the inner side wall of the second slot 3100, thereby realizing modular assembly and rapid assembly of the sound reinforcement equipment.

[0084] The second slot 3100 is provided at least once, and correspondingly, the guide rail 3200 is provided at least once.

[0085] In some examples, the lower surface of the base plate 2201 of the support frame 2200 is provided with a guide rail 3200, and the upper surface of the first speaker 1200 is provided with a second slot 3100. The support frame 2200 is moved and pushed along the upper surface of the first speaker 1200 so that the guide rail 3200 is inserted into the second slot 3100, thereby enabling the support frame 2200 to be snapped into the first speaker 1200.

[0086] Furthermore, the guide rail 3200 is configured as an I-shaped slide rail.

[0087] In some embodiments, the base plate 2201 is provided with a first locking member 2204, and the first speaker 1200 is provided with a limiting hole. The first locking member 2204 can be inserted into the limiting hole to fix the support frame 2200 to the first speaker 1200.

[0088] The first locking member 2204 is threaded onto the base plate 2201 and passes through the base plate 2201. When the support frame 2200 is moved to the set position on the first speaker 1200, the first locking member 2204 is inserted into the corresponding limiting hole, thus fixing and positioning the support frame 2200.

[0089] In some examples, the first locking element 2204 is set as a bolt or stud.

[0090] It should be noted that at least two limiting holes are provided, and each limiting hole is distributed at intervals along the extension direction of the second slot 3100, so that the support frame 2200 can be fixed in multiple different positions in the first speaker 1200.
