[0002] With the increasing popularity of home entertainment systems, soundbars, as devices that provide a high-quality audio experience, have become widely welcomed by consumers. Soundbars are typically designed in a long, rectangular shape, making them easy to place below a TV screen or on a table, saving space while providing stereo sound. The length of soundbars is usually between 50 cm and 120 cm. Their one-piece structure makes them take up considerable space during transportation, increasing shipping costs. Therefore, modular soundbar designs are favored by manufacturers. They only need to be disassembled into two or more sections for packaging and shipping, and users can then assemble them according to the provided instructions.
[0003] However, the detachable design of existing long speaker boxes is relatively complex, and users usually need to perform complicated alignment to complete the splicing operation, which takes a long time. Utility Model Content

[0032] Please refer to Figure 1 , 2 1, 2, 3, 8 and 9, a knob-type modular speaker, comprising a first speaker 10, a second speaker 20, a hinge 30, a cover plate 40 and a knob 50.
[0033] The first speaker 10 and the second speaker 20 are respectively connected to the two movable ends of the hinge 30.
[0034] The first speaker 10 has a through hole 11 at one end connected to the hinge 30. The first speaker 10 has a receiving groove 12 on its side wall. The receiving groove 12 has a half groove 121 at the end away from the through hole 11. The sealing plate 40 covers the half groove 121 to form a main shaft groove.
[0035] The knob 50 is placed in the receiving groove 12. The knob 50 also includes a body 51, a bolt 52 (in this embodiment, the nut of the bolt 52 is hexagonal), a cover plate 53, and multiple fasteners 54 (in this embodiment, the fasteners 54 are fastening screws). The body 51 is disc-shaped, and a boss 511 is provided on one end face of the body 51. The boss 511 has a contoured groove 512. The contoured groove 512 has an internal hexagonal (adapting to the shape of the nut of the bolt 52) structure. The bolt 52 is inserted along one end of the contoured groove 512, and the other end of the bolt 52 passes through the other end face of the body 51. The cover plate 53 is mounted on the boss 511. The cover plate 53 has multiple countersunk holes 532, through which multiple fasteners 54 pass and are locked onto the boss 511 (the design of the countersunk holes 532 can effectively prevent the fasteners 54 from interfering with the receiving groove 12). A main shaft 531 is provided at the end of the cover plate 53 away from the main body 51. The bolt 52 and the main shaft 531 are on the same axis. The main shaft 531 is inserted into the main shaft groove, and the bolt 52 passes through the through hole 11.
[0036] The second speaker 20 is connected to the hinge 30 at one end with a screw hole 21, and the bolt 52 is screwed into the screw hole 21 for fixation.
[0037] Please refer to Figure 8-12 When splicing is required, rotate the hinge 30 to bring the first speaker 10 closer to the second speaker 20 until the bolt 52 contacts the screw hole 21. Quick alignment is achieved by rotating the hinge 30. Rotating the knob 50 then screws the bolt 52 into the screw hole 21 for fixation, thus completing the splicing. This operation is more convenient and faster than other splicing structures.
[0038] Please refer to Figure 3-7 Preferably, the knob 50 further includes an elastic element 55 (preferably a spring in this embodiment), and an annular limiting platform 515 is provided at one end of the main body 51 near the side wall of the first speaker 10. The bolt 52 can slide within the contour groove 512 until the nut of the bolt 52 touches the annular limiting platform 515. The two ends of the elastic element 55 respectively touch the nut of the bolt 52 and the cover plate 53. When the hinge 30 is rotated too quickly, the bolt 52 will carry a large impact force and touch the screw hole 21. When this embodiment encounters such a situation, the bolt 52 will retract into the main body 51 at the moment of contact with the screw hole 21, and compress the elastic element 55 to retract, providing sufficient retraction space for the bolt 52. This design can provide a certain buffering effect, reduce the damage of the bolt 52 to the screw hole 21, and thus improve the service life of the torsion splicing structure.
[0039] Furthermore, a slot 521 is provided at one end of the bolt 52 near the cover plate 53, and one end of the elastic element 55 is inserted into the slot 521; a protrusion 533 extends from the cover plate 53 toward one end of the bolt 52, and the other end of the elastic element 55 is sleeved on the protrusion 533. This can effectively fix the elastic element 55 and prevent the elastic element 55 from shifting during repeated expansion and contraction.
[0040] The main body 51 is provided with a sleeve 513 at the end away from the cover plate 53. The outer wall of the sleeve 513 rotates to contact the through hole 11, and the bolt 52 passes through the sleeve 513. This makes the rotation of the knob 50 smoother.
[0041] The main body 51 has raised textures 514 on its side wall for easy manipulation by the user.
[0042] The sealing plate 40 has a notch 41, and the knob 50 is exposed in the notch 41, which makes it easy for the user to turn the knob 50 while preventing foreign objects from entering the receiving groove 12 and affecting the rotation of the knob 50. Example
[0043] This embodiment, based on Embodiment 1, features a threaded groove in the first speaker enclosure, replaces the threaded hole in the second speaker enclosure with a smooth-walled insertion hole, and flips the knob's bolt and spindle, with the knob body and bolt fixedly connected. Furthermore, the cover plate notch from Embodiment 1 is removed, exposing the knob body, which can then move horizontally in the spindle's extension direction; simultaneously, the internal elastic element is eliminated.
[0044] When disassembly for transport is required, rotate the knob to screw the bolt into the semi-groove of the first speaker (the semi-groove has internal threads). At this time, the knob body moves laterally, causing the main shaft to retract into the side wall of the first speaker. Closing the hinge completes the disassembly and folding of the first and second speakers.
[0045] When it is necessary to assemble them as one unit, unfold the hinge, and the first and second speakers are arranged in a row. Rotate the main body of the knob in the opposite direction to make the bolt unscrew into the half-groove of the first speaker (the half-groove has internal threads). At this time, the main body of the knob moves horizontally towards the second speaker and drives the spindle to insert into the socket of the second speaker to complete the assembly and fixation of the first and second speakers. Example
[0046] Based on Embodiment 1, this embodiment replaces the bolts in Embodiment 1 with nuts, replaces the screw holes of the second speaker in Embodiment 1 with embedded bolts, and the threaded part of the bolts extends out of the side wall of the second speaker.
[0047] When disassembly for transport is required, rotate the knob to separate the nut and bolt (which is embedded in the side wall of the second speaker). At this time, the elastic element is compressed, and the hinge is closed, thus completing the disassembly and folding of the first and second speakers. The elastic element then rebounds, moving the nut to the annular limiting platform.
[0048] When the components need to be assembled as a single unit, unfold the hinges. The first and second speakers are arranged in a row. At this time, some bolts are inserted into the sheath and contact the nut, causing the nut to compress the elastic element (the function of the elastic element here is the same as the buffering function in Embodiment 1, preventing damage to the nut from the rapid impact of the bolt). As the main body of the knob is rotated in the opposite direction, the nut, contacted by the elastic element, will rotate and fit onto the bolt, thus assembling and fixing the first and second speakers.
[0049] This utility model provides a knob-type splicing speaker. A first speaker and a second speaker are respectively connected to the two movable ends of a hinge. A through hole is formed at the end of the first speaker connected to the hinge. A receiving groove is formed on the side wall of the first speaker, and a semi-groove is formed at the end of the receiving groove away from the through hole. A sealing plate is placed on the semi-groove to form a main shaft groove. The knob is placed in the receiving groove, and a coaxial bolt and main shaft are respectively provided at both ends of the knob. The main shaft is inserted into the main shaft groove, and the bolt passes through the through hole. A screw hole is formed at the end of the second speaker connected to the hinge. Rotating the hinge brings the first speaker closer to the second speaker until the bolt contacts the screw hole, achieving quick alignment. Rotating the knob causes the bolt to screw into the screw hole for fixation, thus completing the splicing. This operation is more convenient and faster than other splicing structures.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
