Description

Technical Field

[0001] This invention relates to the field of stage sound system technology, and in particular to an adjustable array stage sound system. Background Technology

[0002] In traditional live events, stages are usually temporary structures, and the selection and placement of speakers, as well as sound absorption and diffusion treatments, are relatively fixed. Multiple speakers are typically arranged side-by-side on the top of the inverted U-shaped acoustic chamber, with their positions relative to each other, forming a line array speaker group to suit small stages. However, this method cannot change the sound direction and playback mode of the speakers, making the stage acoustically unsuitable for various performance scenarios. It can only meet low-level sound quality requirements, affecting the performers' presentation and failing to provide a good auditory experience for the audience. Therefore, designing an adjustable array stage sound system that can flexibly adjust the sound direction and playback mode of the speaker group has become an urgent technical problem to be solved. Summary of the Invention

[0003] To solve the above problems, this utility model provides an adjustable array stage sound system.

[0004] The present invention provides an adjustable array stage sound system, comprising a stage body and several main amplifier boxes. The stage body has a proscenium arch formed by a truss, and symmetrical slide rail assemblies are provided on both sides of the top of the proscenium arch. Each slide rail assembly has multiple main slide rails arranged horizontally along the stage body. The main slide rails extend vertically along the stage body, and their length increases as they approach the center line of the proscenium arch. The front end of the main slide rail is aligned with the front of the proscenium arch, and the rear end is connected to a secondary slide rail. The top of the secondary slide rail is connected to a steering seat, and the steering seat has a vertical rotating shaft that is axially connected to the proscenium arch. The top of the main amplifier boxes is provided with a movable seat. The movable seat, the main slide rails, and the secondary slide rails are all matched, and the movable seat is slidably connected to the main slide rails.

[0005] With the above structure, a movable base is slidably connected to the main slide rail, so that one main amplifier box is connected to each main slide rail. Workers climb the truss, or erect and climb ladders to reach the slide rail assembly, and push the movable base to slide along the main slide rail until it reaches the front end of the main slide rail, aligning the main amplifier boxes with the front of the proscenium arch, forming a horizontal straight line, thus improving the forward sound propagation effect of the main amplifier boxes. By pushing the movable base, the main amplifier boxes are moved to the rear end of the main slide rail, and then slid into the auxiliary slide rail that connects to the main slide rail. Utilizing the main slide rail, which extends longitudinally along the stage body and increases in length as it approaches the center line of the proscenium arch, the main amplifier boxes form a trapezoidal arrangement. Then, the rotating shaft connects to the stage... The rotating seat at the proscenium arch rotates horizontally with the vertical axis, causing the auxiliary slide rail and the main amplifier box to rotate slightly towards the center line of the proscenium arch. This makes the sound from the main amplifier box more concentrated, suitable for situations where the audience is mainly concentrated near the stage. By rotating the rotating seat, the front end of the auxiliary slide rail can be reconnected with the main slide rail, and the movable seat of the main amplifier box can slide back onto the main slide rail. This allows the main amplifier box to be moved along the main and auxiliary slide rails before the performance. When moved to the front end of the main slide rail, it is arranged in a horizontal straight line, providing a better sound effect directly in front. When moved to the auxiliary slide rail and the rotating seat is rotated, it forms a trapezoidal arrangement, concentrating the sound near the front of the stage. This flexibly adapts to the distribution of the audience during the performance, providing a better auditory experience.

[0006] As a further improvement of this utility model, the platform is connected with a positioning clamp that matches the size of the vertical rotating shaft. The positioning clamp is sleeved on the side of the vertical rotating shaft. The positioning clamp includes a pair of semi-circular hoops, one end of which is hinged together, and the other end is provided with a tightening bolt for threaded connection.

[0007] With the above structure, the semi-circular clamp of the positioning clamp is tightened by rotating the tightening bolt. The positioning clamp clamps the vertical shaft from the side, preventing the vertical shaft from rotating further. This ensures that after the main amplifier box moves onto the auxiliary slide rail and the steering seat rotates, the direction of the steering seat remains unchanged, preventing the sound wave vibration from the main amplifier box from causing a change in the orientation of the steering seat. When it is necessary to rotate the steering seat, the tightening bolt is reversed to loosen the positioning clamp from the vertical shaft, restoring the horizontal rotation capability of the vertical shaft.

[0008] As a further improvement of this utility model, a first positioning magnet is embedded in the tail end face of the main slide rail, and a second positioning magnet that attracts the first positioning magnet is embedded in the front end face of the auxiliary slide rail.

[0009] With the above structure, a first positioning magnet is embedded in the end face of the main slide rail, and a second positioning magnet is embedded in the end face of the front face of the auxiliary slide rail, which attracts the first positioning magnet. When the main slide rail and the auxiliary slide rail are connected, the first positioning magnet and the second positioning magnet are magnetically attracted to ensure that the two slide rails remain connected. When the steering seat needs to be rotated back to its original position so that the front end of the auxiliary slide rail is connected to the main slide rail again, the magnetic force of the first positioning magnet when it approaches the second positioning magnet increases, which helps the auxiliary slide rail to align with the main slide rail.

[0010] As a further improvement of this utility model, a third positioning magnet is embedded in the inner wall of the front end of the main slide rail, and a fourth positioning magnet is embedded in the moving seat, which matches the position and magnetic pole of the third positioning magnet.

[0011] With the above structure, a third positioning magnet is embedded in the inner wall of the front end of the main slide rail, and a fourth positioning magnet is embedded in the movable seat that matches the position and magnetic pole of the third positioning magnet. When the main speaker box moves to the front end of the main slide rail, the third positioning magnet and the fourth positioning magnet on the movable seat attract each other, preventing the movable seat from sliding to the rear end of the main slide rail due to the sound wave vibration of the main speaker box, and keeping the main speaker box in a horizontal straight line.

[0012] As a further improvement of this utility model, the front edge of the stage body is provided with a positioning strip and multiple supplementary sound boxes. Multiple T-shaped slots are arranged horizontally on the positioning strip, and the front side of the supplementary sound boxes is provided with a card block that matches the T-shaped slot.

[0013] With the above structure, by inserting the card blocks on the supplementary sound box into the T-shaped card slots at different positions, the position of the supplementary sound box can be flexibly fixed along the front edge of the stage body, covering the broadcast blind spot of the main sound box and optimizing the sound field distribution.

[0014] As a further improvement of this utility model, the front end of the main slide rail and the rear end of the auxiliary slide rail are both closed, the transverse cross section of the steering seat is circular, and the rear end of the main slide rail is provided with a blocking ring. The blocking ring is sleeved on the side of the steering seat and the auxiliary slide rail, and the blocking ring is provided with a notch corresponding to the end of the main slide rail.

[0015] With the above structure, the front end of the main slide rail and the rear end of the auxiliary slide rail are both closed, preventing the moving seat from sliding excessively and falling off the main or auxiliary slide rail. The blocking ring is sleeved on the side of the steering seat and the auxiliary slide rail, and has a notch corresponding to the end of the main slide rail. The moving seat can slide between the main and auxiliary slide rails through the notch. When the moving seat slides onto the auxiliary slide rail and the steering seat is rotated, the front end of the auxiliary slide rail is blocked by the blocking ring, preventing the moving seat from sliding to the front end of the auxiliary slide rail and causing the main speaker box to fall off.

Detailed Implementation

[0022] like Figures 1-5 The present invention discloses an adjustable array stage sound system, comprising a stage body 1 and several main amplifier boxes 2. The stage body 1 is provided with a proscenium arch 3 formed by a truss. Symmetrical slide rail groups are provided on both sides of the top of the proscenium arch 3. Each slide rail group is provided with multiple main slide rails 4 arranged laterally along the stage body 1. The main slide rails 4 are arranged longitudinally along the stage body 1 and their length increases as they approach the center line of the proscenium arch 3. The front end of the main slide rail 4 is aligned with the front of the proscenium arch 3, and the rear end is connected to a secondary slide rail 5. The top of the secondary slide rail 5 is connected to a steering seat 6. The steering seat 6 is provided with a vertical rotating shaft 7 that is axially connected to the proscenium arch 3. The top of the main amplifier boxes 2 is provided with a movable seat 8. The movable seat 8, the main slide rails 4 and the secondary slide rails 5 are all matched, and the movable seat 8 is slidably connected to the main slide rails 4.

[0023] The movable seat 8 is slidably connected to the main slide rail 4, so that one main amplifier box 2 is connected to each main slide rail 4. Workers climb the truss, or set up and climb ladders to reach the slide rail assembly, and push the movable seat 8 to slide along the main slide rail 4. Sliding to the front end of the main slide rail 4, the main amplifier boxes 2 are aligned with the front of the proscenium arch 3, forming a horizontal straight line, allowing the main amplifier boxes 2 to have a better forward sound propagation effect. By pushing the movable seat 8, the main amplifier boxes 2 are moved to the rear end of the main slide rail 4, and then slid into the auxiliary slide rail 5 that connects to the main slide rail 4. Utilizing the fact that the main slide rail 4 extends longitudinally along the stage body 1, with its length increasing as it approaches the center line of the proscenium arch 3, the main amplifier boxes 2 form a trapezoidal arrangement. Then, the rotating shaft connected to the proscenium arch 3... The rotating seat 6 and the vertical pivot 7 rotate horizontally, causing the auxiliary slide rail 5 and the main sound box 2 to rotate slightly towards the center line of the stage opening 3, making the sound propagation of the main sound box 2 more concentrated, which is suitable for situations where the audience is mainly concentrated near the stage; by rotating the rotating seat 6, the front end of the auxiliary slide rail 5 is reconnected with the main slide rail 4, and the moving seat 8 of the main sound box 2 can slide back onto the main slide rail 4; this allows the main sound box 2 to be moved along the main slide rail 4 and the auxiliary slide rail 5 before the performance. When it is moved to the front end of the main slide rail 4, it is arranged in a horizontal straight line, which has a better sound effect when it is directly in front of the stage. When it is moved to the auxiliary slide rail 5 and the rotating seat 6 is rotated, it forms a trapezoidal arrangement, which concentrates the sound near the front of the stage, flexibly adapting to the distribution of the audience during the performance and providing a better auditory experience.

[0024] The platform 3 is connected to a positioning clamp 9 that matches the size of the vertical rotating shaft 7. The positioning clamp 9 is fitted on the side of the vertical rotating shaft 7. The positioning clamp 9 includes a pair of semi-circular hoops, one end of which is hinged and the other end is provided with a tightening bolt for threaded connection.

[0025] By rotating the tightening bolt, the semi-circular hoop of the positioning clamp 9 is tightened, and the positioning clamp 9 clamps the vertical shaft 7 from the side, preventing the vertical shaft 7 from continuing to rotate. After the main sound box 2 moves onto the auxiliary slide rail 5 and the steering seat 6 is rotated, the direction of the steering seat 6 remains unchanged, preventing the sound wave vibration of the main sound box 2 from causing the orientation of the steering seat 6 to change. When it is necessary to rotate the steering seat 6, the tightening bolt is reversed to loosen the positioning clamp 9 from the vertical shaft 7, restoring the horizontal rotation capability of the vertical shaft 7.

[0026] The tail end face of the main slide rail 4 is embedded with a first positioning magnet 10, and the front end face of the auxiliary slide rail 5 is embedded with a second positioning magnet 11 that attracts the first positioning magnet 10.

[0027] The main slide rail 4 has a first positioning magnet 10 embedded at its tail end face, and the secondary slide rail 5 has a second positioning magnet 11 embedded at its front end face that attracts the first positioning magnet 10. When the main slide rail 4 and the secondary slide rail 5 are connected, the first positioning magnet 10 and the second positioning magnet 11 are magnetically attracted to each other, ensuring that the two slide rails remain connected. When the steering seat 6 needs to be rotated back to its original position so that the front end of the secondary slide rail 5 is connected to the main slide rail 4 again, the magnetic force of the first positioning magnet 10 when it approaches the second positioning magnet 11 increases, which helps the secondary slide rail 5 to align with the main slide rail 4.

[0028] The front inner wall of the main slide rail 4 is embedded with a third positioning magnet 12, and the movable seat 8 is embedded with a fourth positioning magnet 13 that matches the position and magnetic pole of the third positioning magnet 12.

[0029] A third positioning magnet 12 is embedded in the inner wall of the front end of the main slide rail 4, and a fourth positioning magnet 13 is embedded on the movable seat 8 that matches the position and magnetic pole of the third positioning magnet 12. When the main sound amplifier box 2 moves to the front end of the main slide rail 4, the third positioning magnet 12 and the fourth positioning magnet 13 on the movable seat 8 are attracted to each other, so as to prevent the movable seat 8 from sliding to the rear end of the main slide rail 4 due to the sound wave vibration of the main sound amplifier box 2, and keep the main sound amplifier box 2 in a horizontal straight line.

[0030] The front edge of the stage body 1 is provided with a positioning strip 14 and multiple supplementary sound boxes 15. Multiple T-shaped slots 16 are arranged horizontally on the positioning strip 14, and the front side of the supplementary sound box 15 is provided with a card block 17 that matches the T-shaped slot 16.

[0031] By inserting the locking block 17 on the supplementary sound box 15 into the T-shaped slot 16 at different positions, the supplementary sound box 15 can be flexibly fixed along the front edge of the stage body 1 to cover the broadcast blind spot of the main sound box 2 and optimize the sound field distribution.

[0032] The front end of the main slide rail 4 and the rear end of the auxiliary slide rail 5 are both closed. The transverse cross section of the steering seat 6 is circular. The rear end of the main slide rail 4 is provided with a blocking ring 18. The blocking ring 18 is sleeved on the side of the steering seat 6 and the auxiliary slide rail 5. The blocking ring 18 is provided with a notch corresponding to the end of the main slide rail 4.

[0033] The front end of the main slide rail 4 and the rear end of the auxiliary slide rail 5 are both closed to prevent the movable seat 8 from sliding excessively and falling off the main slide rail 4 or the auxiliary slide rail 5. The blocking ring 18 is sleeved on the side of the steering seat 6 and the auxiliary slide rail 5 and has a notch corresponding to the end of the main slide rail 4. The movable seat 8 can slide between the main slide rail 4 and the auxiliary slide rail 5 through the notch. When the movable seat 8 slides onto the auxiliary slide rail 5 and the steering seat 6 is rotated, the front end of the auxiliary slide rail 5 is blocked by the blocking ring 18 to prevent the movable seat 8 from sliding onto the front end of the auxiliary slide rail 5 and causing the main speaker box 2 to fall off.
