Description

Technical Field

[0001] This utility model relates to the field of audio testing technology, specifically to a multi-directional sound source acquisition device rack for audio testing. Background Technology

[0002] Audio testing is a crucial step in ensuring that the audio system performs at its best. It checks whether the phase relationship between the various speaker units in the audio system is correct, and ensures that the sound propagates and superimposes well in space.

[0003] With societal progress, people yearn for a more colorful life. Singing and dancing, as a form of entertainment passed down for thousands of years, are deeply ingrained in the lives of people of all ethnic groups. However, with the development and progress of technology, people have increasingly higher and more demanding requirements for the performance styles and venues of singing and dancing. Audio equipment has also been produced to meet these needs. During audio equipment production, testing equipment is needed to inspect the equipment. Existing testing equipment lacks the function of damping the equipment during testing. When the audio equipment is playing, sound waves diffuse outwards. If the volume is too high, it can easily cause external objects to vibrate. If this is not addressed, it can easily lead to equipment displacement. Furthermore, it is impossible to replace the sound-collecting components according to testing needs during use. At the same time, during long-term testing, the sound-collecting components are prone to aging or damage. To solve these technical problems, we have designed a multi-directional sound source acquisition device rack for audio equipment testing. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-directional sound source acquisition device rack for audio testing, which has the advantages of shock absorption protection for the equipment and easy replacement of the sound receiving components. It solves the problems of not having the function of shock absorption for the equipment, sound waves spreading outward during testing, which can easily cause vibration of the object if the volume is too loud, and the inability to replace the sound receiving components. At the same time, the sound receiving components are also prone to aging or damage during long-term testing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional sound source acquisition device frame for audio testing, comprising a supporting base box, a fixed frame fixedly installed on the top of the supporting base box, a control host fixedly installed on the left side of the inner cavity of the supporting base box, a storage battery fixedly installed on the right side of the inner cavity of the supporting base box, support mechanisms provided on both sides of the supporting base box, a drive motor fixedly installed on the top of the inner cavity of the fixed frame, the output end of the drive motor extending through to the top of the fixed frame and fixedly installed with a lifting column, a placement plate movably installed on the top of the lifting column, limit bolts through both sides of the lifting column, a microphone acquisition device movably installed in the inner cavity of the placement plate, a disassembly and assembly mechanism provided at the bottom of the placement plate, the disassembly and assembly mechanism including a mounting frame fixedly installed on the surface of the lifting column, and the support mechanism including a positioning clamp fixedly installed on the surface of the supporting base box.

[0006] Preferably, a second threaded rod is installed through the top of the positioning clamp, a threaded plate is threaded on the surface of the second threaded rod, and the bottom of the threaded plate extends through to the bottom of the positioning clamp and is fixedly connected to a connecting plate.

[0007] Preferably, dampers are fixedly installed on both sides of the bottom of the connecting plate, and a limit plate is fixedly installed on the bottom of the damper.

[0008] Preferably, mounting blocks are fixedly connected to both sides of the bottom of the placement tray, the mounting blocks are movably installed in the inner cavity of the mounting frame, and a limit rod is installed through the right side of the mounting frame.

[0009] Preferably, a first threaded rod is fixedly mounted on the top of the placement tray via a bearing, and a positioning clamp is threaded onto the surface of the first threaded rod.

[0010] Preferably, reinforcing plates are fixedly installed on both sides of the fixing frame, and partition plates are fixedly installed longitudinally in the inner cavity of the supporting base box.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model, through the cooperation of a lifting column, limiting bolt, placement plate, drive motor, mounting frame, mounting block, limiting rod, first threaded rod, positioning clamp, second threaded rod, threaded plate, connecting plate, damper, and limiting plate, can provide seismic support for the equipment. In use, the second threaded rod will drive the connecting plate and damper to move through the threaded plate, so that the damper can cooperate with the limiting plate to support the equipment against seismicity and prevent the equipment from moving due to vibration. In addition, the limiting rod can also be released from the limiting position of the mounting block during use, so that the user can replace the placement plate and prevent the radio components from aging or being damaged during long-term testing.

A control host 9 is fixedly installed on the left side of the inner cavity of the supporting base box 1, and a storage battery 10 is fixedly installed on the right side of the inner cavity of the supporting base box 1. Support mechanisms 11 are provided on both sides of the supporting base box 1. A drive motor 12 is fixedly installed on the top of the inner cavity of the fixing frame 2. The output end of the drive motor 12 extends through to the top of the fixing frame 2 and is fixedly installed with a lifting column 4. A placement plate 6 is movably installed on the top of the lifting column 4. Limit bolts 5 are installed through both sides of the lifting column 4. A microphone acquisition device 8 is movably installed in the inner cavity of the placement plate 6. A disassembly and assembly mechanism 7 is provided at the bottom of the placement plate 6. The disassembly and assembly mechanism 7 includes a mounting frame 13, which is fixedly installed on the surface of the lifting column 4. The support mechanism 11 includes a positioning clamp 17, which is fixedly installed on the surface of the supporting base box 1. By setting the limit bolts 5, the extension length of the lifting column 4 can be limited to prevent the lifting column 4 from retracting.

[0020] Please see Figure 1 , Figure 2 and Figure 4 The top of the positioning clamp 17 is fitted with a second threaded rod 18, and the surface of the second threaded rod 18 is threaded with a threaded plate 19. The bottom of the threaded plate 19 extends to the bottom of the positioning clamp 17 and is fixedly connected to a connecting plate 20. By setting the connecting plate 20, it is convenient to install the damper 21.

[0021] Please see Figure 1 , Figure 2 and Figure 4 Dampers 21 are fixedly installed on both sides of the bottom of the connecting plate 20. Limiting plates 22 are fixedly installed at the bottom of the dampers 21. By setting the limiting plates 22, the anti-slip properties of the equipment can be increased, and the equipment can also be prevented from shifting.

[0022] Please see Figure 1 , Figure 2 and Figure 3 Both sides of the bottom of the placement plate 6 are fixedly connected to the mounting blocks 14. The mounting blocks 14 are movably installed in the inner cavity of the mounting frame 13. A limit rod 15 is installed through the right side of the mounting frame 13.

[0023] Please see Figure 1 , Figure 2 and Figure 3 The top of the placement plate 6 is fixedly mounted with a first threaded rod 16 by a bearing. The surface of the first threaded rod 16 is threaded with a positioning clamp 17. Through the cooperation of the first threaded rod 16 and the positioning clamp 17, the microphone collector 8 can be limited and fixed, and the microphone collector 8 can also be replaced.

[0024] Please see Figure 1 andFigure 2 Reinforcing plates are fixedly installed on both sides of the mounting bracket 2, and a partition plate is fixedly installed longitudinally inside the support base box 1. By setting the reinforcing plates, the stability of the mounting bracket 2 can be increased. By setting the partition plate, the space inside the support base box 1 can be divided to facilitate the installation of the control host 9 and the battery 10.

[0025] Please see Figure 1 and Figure 2 A push rod is fixedly installed on the right side of the support base box 1. Movable casters are fixedly installed at the four corners of the bottom of the support base box 1. A display screen 3 is fixedly installed on the front side of the top of the support base box 1. By setting the push rod, it is convenient for the user to push the equipment to move it to a suitable position.

[0026] In use, the user first moves the equipment to the test site, then adjusts the height of the placement plate 6 according to the position of the speaker. Next, the user stretches the lifting column 4 to adjust its height. After this, the user tightens the limiting bolt 5 to fix the height of the lifting column 4. Then, the user adjusts the support mechanism 11. During adjustment, the user rotates the second threaded rod 18, causing it to drive the threaded plate 19 downwards via the thread. The threaded plate 19 then drives the damper 21 and the limiting plate 22 to move via the connecting plate 20, until the equipment can be supported by the limiting plate 22. This allows the limiting plate 22 to cooperate with the damper 21 to increase the equipment's stability. The device is designed to withstand shocks and prevent it from shaking due to external factors, thus preventing the microphone acquisition unit 8 from shifting position. During use, the user can rotate the first threaded rod 16 to move the positioning clamp 17, thereby releasing the restriction on the microphone acquisition unit 8 and allowing for replacement. The user can also disassemble and replace the placement tray 6. If a different model of placement tray 6 needs to be replaced, the user can pull the limiting rod 15 out of the mounting frame 13 to release the restriction on the mounting block 14, and then remove the placement tray 6 from the lifting column 4 for easy replacement.
