Description

Technical Field

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

[0002] An important device in the sound system is the speaker, which is generally composed of a speaker unit and a cabinet. The speaker unit is the sound-generating component, and the cabinet complements the speaker unit and plays the role of correcting the sound. The sound-generating principle of the speaker unit is a conversion of electrical energy into sound. When different electron energies are transmitted to the coil, the coil generates a kind of energy that interacts with the magnetic field of the magnet. This interaction causes the paper plate to vibrate. Because the electron energy changes at any time, the speaker coil will move forward or backward, so the speaker paper plate will move with it. These actions change the density of the air and produce sound.

[0003] Stage speakers vibrate when they are working. The vibration of the speakers may bring the following disadvantages: it may cause distortion and blurring of the sound, affecting the clarity and fidelity of the sound. Long-term strong vibration may loosen and damage the internal electronic components and speakers, shortening the service life of the speakers. Vibration may cause abnormal noise and reduce the listening experience.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the audio body vibrates during operation, when the vibration occurs in the up and down directions, the structure composed of the horizontal assembly frame will vibrate up and down, the structure composed of the first rotating rod and the second rotating rod will rotate relatively, and the positive and negative threaded screws will carry the internal threaded sleeve to move laterally in the sliding rod. When the internal threaded sleeve moves laterally in the sliding rod, the internal threaded sleeve will drive the fixed sleeve to move laterally in the sliding rod, thereby applying pressure to the first buffer spring to deform the first buffer spring to generate a reverse elastic force to buffer the vibration in the up and down directions. At the same time, the audio body will also generate lateral vibration when working. When the audio body vibrates laterally, the vertical connecting plate will pressurize the vertical guide rail. After the vertical guide rail is compressed, the vertical guide rail transfers the pressure to the second buffer spring and the telescopic rod. The second buffer spring is deformed to generate a reverse elastic force to buffer the lateral vibration of the audio body, so as to alleviate the vibration generated by the operation of the audio body, greatly reduce the shaking of the audio body, thereby reducing the damage of the vibration to the internal electronic components and speakers of the audio, and extending the service life of the audio.

[0017] 2. According to the needs of the installation height, the driving rod is rotated, 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 move 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 move 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 groove 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, so that the sound propagation is more uniform and clearer, and the use effect is improved.

[0018] 3. Adjust the relative position between the fixed mounting seat and the movable mounting plate according to installation needs, rotate the rotating limit plate so that the rotating 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 groove to limit the movement 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 audio body can be placed in a corner to improve the installation convenience of the audio 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 audio body can also be placed in the most suitable position according to the size and shape of the space to improve space utilization.

[0019] 4. According to work needs, install the anti-skid gasket on the bottom of the lifting base. The anti-skid gasket is in contact with the bottom to improve the stability of the audio 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

[0043] 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.

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

[0045] Working principle:

[0046] The first step: adjust the relative position between the fixed mounting seat 5 and the movable mounting plate 6 according to the installation needs, rotate the rotating limit plate 20 so that the rotating 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.

[0047] Step 2: According to the needs of the installation height, the driving rod 16 is rotated, and the rotation of the driving rod 16 drives the positive and negative screw rods 15 to rotate. 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 groove 3 will also move in the vertical guide rail 29 to adapt to the change in the distance between the horizontal assembly frames 8.

[0048] Step 3: When the sound 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, the structure composed of the first rotating rod 9 and the second rotating rod 10 will rotate relatively, and the positive and negative threaded rod 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 deform the first buffer spring 19 to generate a reverse elastic force to buffer the vibration in the up and down directions. At the same time, the sound body 1 will also generate lateral vibration when working. When the sound body 1 vibrates laterally, the vertical connecting plate 30 will press 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 sound body 1, so as to alleviate the vibration generated by the operation of the sound body 1 and greatly reduce the shaking of the sound body 1.

[0049] Step 4: According to work needs, install the anti-skid pad 24 on the bottom of the lifting base 7, and the anti-skid pad 24 contacts the bottom to improve the stability of the speaker body 1 installed on the ground.
