Description

Technical Field

[0001] This utility model relates to the field of audio circuit board technology, specifically to a vibration-damping audio circuit board. Background Technology

[0002] Audio circuit boards contain components such as capacitors and resistors. During installation and use, vibration damping pads or dampers are placed on the mounting surface to dampen the vibrations generated during use, thereby ensuring the operation of the components on the audio circuit board and the quality of the audio signal.

[0003] While using vibration damping pads or shock absorbers to install audio circuit boards can improve the vibration damping effect, the installation of audio circuit boards requires multiple points. Due to differences in size between different mounting surfaces or vibration damping pads / shock absorbers, the installation level of the vibration damping pads or shock absorbers may exceed the tolerance. Errors in the installation level of the audio circuit board can cause its natural frequency to approach or coincide with the vibration frequency of the audio circuit board during operation (such as vibrations generated by equipment operation, external environmental vibrations, etc.), thereby triggering resonance. This significantly amplifies the vibration transmission, reduces the vibration damping effect, and seriously affects the audio signal quality, producing problems such as noise and distortion.

[0004] Therefore, there is an urgent need for a vibration-damping audio circuit board to solve the above problems. Utility Model Content

[0009] The drive assembly includes two symmetrically arranged threaded rods rotatably connected to the fixed ring near the adjusting ring. The sidewalls of the two threaded rods are threaded with drive tubes. The ends of the two drive tubes away from the fixed ring are connected to the adjusting ring.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1-6 The diagram shows a vibration-damping audio circuit board, which includes a board body 101 and a mounting plate 102, and also includes a vibration damping component disposed on the mounting plate 102 for damping the board body 101, and an adjustment component disposed on the vibration damping component for adjusting the mounting level of the board body 101.

[0025] The vibration damping assembly includes four damping tubes 201 arranged symmetrically in pairs and fixedly connected to the mounting plate 102 near the plate body 101. The four damping tubes 201 are slidably connected to damping plates 202. The four damping plates 202 are fixedly connected to damping rods 203 on the side near the plate body 101. The side of the damping plates 202 away from the damping rods 203 is fixedly connected to springs 204. The ends of the four springs 204 away from the damping plates 202 are connected to the bottom wall of the damping tubes 201. The four damping tubes 201 are filled with damping fluid. The four damping plates 202 have multiple damping holes 205.

[0026] It should be noted that the vibration damping components provide a vibration damping effect for the board 101, ensuring the safety of the components on the board 101 and the quality of the audio signal.

[0027] It is worth noting that the specific structure and working principle of audio circuit boards are already known to those in the field, and will not be elaborated upon here.

[0028] Please see Figures 1-6 The adjustment assembly shown in the figure includes a fixing ring 301 fixedly connected to the side wall of the four damping rods 203, and an adjustment ring 302 connected to the side of the four fixing rings 301 near the plate 101 via a drive assembly.

[0029] It should be noted here that by adjusting the settings of the components, the level of the plate 101 after installation and fixation can be adjusted, thereby reducing the risk that the natural frequency will be close to or coincide with the vibration frequency of the plate 101 during operation due to the error in the level of the plate 101 installation, thus reducing the probability of resonance.

[0030] Please see Figures 1-3 The plate 101 in the figure has mounting holes 207 at each of its four corners. Screws 208 are inserted into the four mounting holes 207. The four damping rods 203 have threaded holes 206 on the side near the plate 101. The four threaded holes 206 are matched with the screws 208.

[0031] It should be noted here that the mounting holes 207 and screws 208 are used to press and fix the plate 101.

[0032] Please see Figures 3-5 The driving assembly shown in the figure includes two symmetrically arranged threaded rods 401 rotatably connected to the fixed ring 301 near the adjusting ring 302. The sidewalls of the two threaded rods 401 are threaded with driving tubes 402. The ends of the two driving tubes 402 away from the fixed ring 301 are connected to the adjusting ring 302. The fixed ring 301 is provided with a linkage assembly for synchronously rotating the two threaded rods 401. The ends of the two threaded rods 401 away from the fixed ring 301 are provided with hexagonal driving holes 403. The adjusting ring 302 and the plate 101 are respectively provided with two through holes 404. Each through hole 404 is concentrically arranged with the driving tube 402.

[0033] It should be noted here that the height of the adjusting ring 302 is adjusted by setting the drive component.

[0034] Please see Figure 3The fixed ring 301 in the figure is provided with a guide assembly for guiding the movement of the adjusting ring 302. The guide assembly includes two guide rods 501 fixedly connected to the side of the fixed ring 301 near the adjusting ring 302. The two guide rods 501 are located on both sides of the two threaded rods 401 respectively. The two guide rods 501 are slidably connected to guide tubes 502. The ends of the two guide tubes 502 away from the fixed ring 301 are connected to the adjusting ring 302.

[0035] It should be noted here that the guide component is used to guide and limit the movement of the adjusting ring 302.

[0036] Working principle: When installing the plate 101, first insert the mounting holes 207 at the four corners of the plate 101 into the vibration damping rod 203, so that one side of the plate 101 abuts against the adjusting ring 302 on the side wall of the vibration damping rod 203. Then, through the threaded connection of the four screws 208 with the threaded hole 206 at one end of the vibration damping rod 203, the plate 101 is pressed and fixed.

[0037] After the plate 101 is pressed and fixed, the flatness of the plate 101 can be checked using a dial indicator. When the installation flatness of the plate 101 does not meet the installation requirements, an Allen wrench can be inserted into the drive hole 403 at one end of the threaded rod 401 through the through hole 404 on the plate 101 and the adjusting ring 302. By rotating the Allen wrench, the threaded rod 401 is rotated. At the same time, under the action of the linkage component, the other threaded rod 401 is driven to rotate synchronously. Then, under the thread meshing transmission action of the threaded rod 401 and the drive tube 402 and the guiding action of the guide component, the adjusting ring 302 is driven to move up and down. Thus, by using the up and down movement of the adjusting ring 302, the installation level of the plate 101 is adjusted. Finally, the accuracy of the plate 101 level adjustment is ensured by checking with a dial indicator.

[0038] After the plate 101 is installed, fixed, and leveled, it can be used normally. During the use of the plate 101, when the plate 101 is subjected to vibration, the plate 101 can be subjected to double-layer vibration reduction under the elastic force of the spring 204 and the damping action of the damping fluid (the working principle of the vibration damping component in this application is similar to that of the damping shock absorber, and as prior art, it will not be described in detail here). This provides a vibration reduction effect for the plate 101, ensuring the safety of the components on the plate 101 and the quality of the audio signal. In addition, the plate 101 is leveled during installation and use, which reduces the risk that the natural frequency will be close to or coincide with the vibration frequency of the plate 101 during operation due to the error in the level of the plate 101 installation, thereby reducing the probability of resonance and ensuring the vibration reduction effect of the vibration damping component on the plate 101.

[0039] Example 2

[0040] Please see Figure 4 This embodiment further illustrates Example 1. The linkage component shown in the figure includes a linkage ring 601 rotatably connected to the fixed ring 301 near the adjusting ring 302. Two arc-shaped gear rings 602 are fixedly connected to the side of the linkage ring 601 near the two threaded rods 401. Gears 603 are fixedly connected to the side walls of the two threaded rods 401. The two gears 603 and the arc-shaped gear rings 602 are meshed with each other. The fixed ring 301 is provided with a limiting component for limiting the rotation of the linkage ring 601.

[0041] It should be noted that, through the linkage component, when one of the two threaded rods 401 is rotated, the meshing transmission between the gear 603 and the arc-shaped gear ring 602 will drive the other arc-shaped gear ring 602 of the linkage ring 601 to rotate. In turn, under the meshing transmission between the arc-shaped gear ring 602 and the gear 603, the other threaded rod 401 will rotate synchronously, thereby ensuring the stability of the height adjustment of the adjusting ring 302.

[0042] Example 3

[0043] Please see Figure 6 This embodiment is a further explanation of other embodiments. The limiting component in the figure includes an annular limiting groove 701 opened on the side of the fixed ring 301 near the linkage ring 601. The annular limiting groove 701 is rotatably connected to a plurality of limiting plates 702, and one end of each limiting plate 702 is connected to the linkage ring 601.

[0044] It should be noted that the setting of the limit component provides guidance and limit for the rotation of the linkage ring 601, thereby improving the stability of the rotation of the linkage ring 601.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
