Description

Technical Field

[0001] The present invention relates to the technical field of loudspeaker vibration reduction, in particular to a stage sound system with a built-in extended track type vibration reduction component. Background Art

[0002] A crucial component of any audio system is the speaker, which typically consists of a speaker unit and a cabinet. The speaker unit is the sound-producing component, while the cabinet complements the unit and modifies the sound. The principle of sound production in a speaker unit is the conversion of electrical energy into sound. When varying electron energies are transmitted to the coil, the coil generates energy that interacts with the magnetic field of the magnet. This interaction causes the disc to vibrate. As the electron energy fluctuates, the speaker coil moves forward or backward, and the disc moves accordingly. These movements cause the density of the air to change, producing sound.

[0003] When the stage sound system is working, it will vibrate. The vibration of the sound system may bring the following disadvantages:

[0004] It may cause sound distortion and blur, affecting the clarity and fidelity of the sound. Long-term strong vibration may loosen and damage internal electronic components and speakers, shortening the service life of the audio. Vibration may cause abnormal noise and reduce the listening experience. In order to reduce the impact of vibration on the audio, a new type of stage audio with a built-in extended track shock-absorbing component is proposed. Summary of the Invention

Pairs of vertical guide rails are movably mounted in the U-shaped sleeve, and a vertical connecting plate is provided between two adjacent vertical guide rails. The vertical connecting plate is fixedly connected to the top of the lifting base, and a telescopic rod and a circular seat are provided between the vertical guide rails and the end fixing plates.

[0018] 2. According to the needs of the installation height, rotate the driving rod, and the rotation of the driving rod drives the positive and negative screw rods to rotate. When the positive and negative screw rods rotate, the internal threaded sleeves mounted on the positive and negative screw rods are driven to move closer to each other. When the two internal threaded sleeves are close to each other, the two sliding rods are driven to move closer to each other, thereby increasing the distance between the two horizontal assembly frames and raising the sound body. When the two internal threaded sleeves are moved away from each other, the distance between the two horizontal assembly frames will be reduced, lowering the sound body. When the two internal threaded sleeves are moved closer to or away from each other, the rotating collar also rotates on the sliding rod. When the distance between the horizontal assembly frames changes, the horizontal assembly slot will also move in the vertical guide rail to adapt to the change in the distance between the horizontal assembly frames. By changing the height of the sound body, the sound body can be adjusted to the optimal height according to different stage layouts and audience positions, making the sound propagation more uniform and clearer, thereby improving the use effect.

[0019] 3. Adjust the relative position between the fixed mounting base and the movable mounting plate according to installation needs, rotate the rotary limit plate so that the rotary limit plate no longer limits the movable mounting plate, and the movable mounting plate moves laterally under the guidance of the circular positioning plate. The circular positioning plate moves in the through groove to limit the movement range of the movable mounting plate. The lateral movement of the movable mounting plate drives the lifting base and the anti-slip gasket to move, thereby changing the placement position of the anti-slip gasket. The speaker body can be placed in a corner position to improve the installation convenience of the speaker body. The base position can be reasonably adjusted according to the position of the peripheral equipment and the line layout to make the wiring neater and the connection smoother. The speaker body can also be placed in the most suitable position according to the size and shape of the space to improve space utilization.

[0020] 4. According to work needs, install the anti-slip gasket on the bottom of the lifting base. The anti-slip gasket contacts the bottom to improve the stability of the speaker body installed on the ground. Stable installation can reduce structural fatigue and damage caused by vibration and extend the service life. BRIEF DESCRIPTION OF THE DRAWINGS

The positive and negative threaded rod 15 is located in the internally threaded sleeve 17 and is threadedly connected to the internally threaded sleeve 17.

[0040] A rotating limit plate 20 is rotatably connected to the fixed mounting seat 5, and the bottom of the rotating limit plate 20 is fitted with the side of the movable mounting plate 6. Through the rotation of the rotating limit plate 20 on the fixed mounting seat 5, the rotating limit plate 20 limits the side of the movable mounting plate 6 or allows the movable mounting plate 6 to move laterally. A through groove 21 is provided on the movable mounting plate 6, and a circular positioning plate 22 located in the through groove 21 is provided at the bottom of the fixed mounting seat 5. Through the lateral misalignment movement between the movable mounting plate 6 and the fixed mounting seat 5, the position of the lifting base 7 and the anti-slip gasket 24 in the audio body 1 is changed.

A vertical connecting plate 30 is provided between two adjacent vertical guide rails 29. A groove is provided on one side of the vertical guide rail 29 close to the vertical connecting plate 30. The shapes of the grooves on both sides of the vertical connecting plate 30 are the same as those on the vertical guide rails 29. To ensure the lifting stability of the vertical connecting plate 30 and guide the lifting of the vertical connecting plate 30, the vertical connecting plate 30 is fixedly connected to the top of the lifting base 7. A telescopic rod 31 and a circular seat 32 are provided between the vertical guide rail 29 and the end fixing plate 28.

[0044] A pulley 34 is provided at the top of the vertical guide rail 29, and the pulley 34 fits against the top of the inner wall of the U-shaped sleeve 27. Through the contact between the pulley 34 and the U-shaped sleeve 27, the resistance of the vertical guide rail 29 sliding in the U-shaped sleeve 27 is reduced, thereby improving the sliding convenience of the vertical guide rail 29.

[0045] A center positioning plate 35 fixed to the upper surface of the lifting base 7 is provided between the vertical guide rails 29, and telescopic rods 31 are also provided on both sides of the center positioning plate 35, and the circular seats 32 at both ends of the telescopic rods 31 are respectively fixed on the vertical guide rails 29 and the center positioning plate 35.

Similarly, the telescopic rods 31 and the second buffer springs 33 are pressurized by the movement of the vertical guide rails 29, and the generated elastic force is used to buffer the shaking of the movement of the vertical guide rails 29.

[0046] Working principle:

[0047] Step 1: Adjust the relative position between the fixed mounting seat 5 and the movable mounting plate 6 according to the installation needs, rotate the rotary limit plate 20 so that the rotary limit plate 20 no longer limits the movable mounting plate 6, and the movable mounting plate 6 moves laterally under the guidance of the circular positioning plate 22. The circular positioning plate 22 moves in the through groove 21 to limit the movement range of the movable mounting plate 6. The lateral movement of the movable mounting plate 6 drives the lifting base 7 and the anti-slip gasket 24 to move, thereby changing the placement position of the anti-slip gasket 24. The audio body 1 can be placed at a corner position, which improves the installation convenience of the audio body 1.

[0048] Step 2: Rotate the drive rod 16 according to the needs of the installation height, and drive the positive and negative screw rods 15 to rotate through the rotation of the drive rod 16. When the positive and negative screw rods 15 rotate, the internal threaded sleeves 17 sleeved on the positive and negative screw rods 15 are driven to move closer to each other. When the two internal threaded sleeves 17 are close to each other, the two sliding rods 12 are driven to move closer to each other, thereby increasing the distance between the two horizontal assembly frames 8 and raising the audio body 1. When the two internal threaded sleeves 17 move away from each other, the distance between the two horizontal assembly frames 8 will be reduced, and the audio body 1 will be lowered. When the two internal threaded sleeves 17 move closer to or away from each other, the rotating collar 13 also rotates on the sliding rod 12. When the distance between the horizontal assembly frames 8 changes, the horizontal assembly slot 3 will also move in the vertical guide rail 29 to adapt to the change in the distance between the horizontal assembly frames 8.

[0049] Step 3: When the speaker body 1 vibrates during operation, when vibration occurs in the up and down directions, the structure composed of the horizontal assembly frame 8 will vibrate up and down, and the structure composed of the first rotating rod 9 and the second rotating rod 10 will rotate relative to each other. The positive and negative threaded screw 15 will carry the internal threaded sleeve 17 to move laterally in the sliding rod 12. When the internal threaded sleeve 17 moves laterally in the sliding rod 12, the internal threaded sleeve 17 will drive the fixed collar 18 to move laterally in the sliding rod 12, thereby applying pressure to the first buffer spring 19 to cause the first buffer spring 19 to deform and generate a reverse elastic force to buffer the vibration in the up and down directions. At the same time, the speaker body 1 will also generate lateral vibration during operation. When the speaker body 1 vibrates laterally, the vertical connecting plate 30 will apply pressure to the vertical guide rail 29. After the vertical guide rail 29 is compressed, the vertical guide rail 29 transfers the pressure to the second buffer spring 33 and the telescopic rod 31. The second buffer spring 33 is deformed to generate a reverse elastic force to buffer the lateral vibration of the speaker body 1, thereby alleviating the vibration generated by the operation of the speaker body 1 and greatly reducing the shaking of the speaker body 1.

[0050] Step 4: According to work needs, install the anti-skid pad 24 on the bottom of the lifting base 7. The anti-skid pad 24 contacts the bottom to improve the stability of the speaker body 1 installed on the ground.
