[0002] Multi-band acoustic mesh is an acoustic filter mesh with multiple frequency response characteristics. It can provide effective acoustic filtering effects in different frequency ranges. For acoustic mesh installed on audio speakers, it is usually bonded to the corresponding product components using glue or double-sided tape.

[0003] The speakers will vibrate when working, especially when used for a long time at a high volume, the vibration will be more intense, and the long-term vibration will cause the installation state of the mesh to gradually become loose, and when the mesh is loose, its original acoustic characteristics will change, causing the mid- and high-frequency directivity of the speaker to become less accurate, thereby affecting the overall performance of the sound quality, and the loose mesh will increase the scattering and absorption of sound, resulting in a decrease in sound transmittance, making the sound emitted by the speaker less clear and bright, and the acoustic mesh is bonded to the corresponding product components with glue or double-sided tape, making it difficult to adjust the looseness of the acoustic mesh, resulting in the need to replace the acoustic mesh to maintain the performance of the speaker, thereby reducing the utilization rate of the acoustic mesh while increasing the cost of using the speaker.

[0004] Therefore, there is an urgent need for a multi-band acoustic mesh adjustment device to solve the above problems. Utility Model Content

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1

[0023] Please refer to Figures 1 - 5 , a multi-band acoustic mesh adjustment device in the figure, includes an acoustic mesh body 102 and a fixed ring 101, and further includes an adjustment component provided on the fixed ring 101 for adjusting the relaxation deformation of the acoustic mesh body 102 under a long-term vibration environment;

[0024] The adjustment component includes an adjustment hole 201 opened on the inner wall of the fixed ring 101. The adjustment hole 201 is slidably connected with an adjustment ring 202. The outer wall of the acoustic mesh body 102 is adhered to the inner wall of the adjustment ring 202 by glue or double-sided tape. A connecting ring 203 is fixedly connected to the side of the adjustment ring 202 away from the acoustic mesh body 102. The fixed ring 101 is provided with a driving component for driving the connecting ring 203;

[0025] It should be noted here that: through the setting of the adjustment component, under the action of the driving component, the acoustic mesh body 102 is circularly pulled, thereby reducing the relaxation degree of the acoustic mesh body 102 under a long-term vibration environment. While ensuring the service performance of the acoustic mesh body 102, the utilization rate of the acoustic mesh body 102 is improved, and further, the replacement frequency of the acoustic mesh body 102 and the use cost of the speaker are reduced.

[0026] Please refer to Figures 2 - 5, in the illustrated driving assembly, a driving cavity 304 is formed in the fixed ring 101. A driving ring 301 is slidably connected to the driving cavity 304. One side of the connecting ring 203 away from the adjusting ring 202 is connected to the driving ring 301. Two symmetrically arranged pushing rings 302 are slidably connected to the driving cavity 304. The two pushing rings 302 are located on both sides of the driving ring 301. An inclined surface 303 is formed on one side of the two pushing rings 302 close to the driving ring 301. The driving cavity 304 is provided with a moving assembly for moving the two pushing rings 302;

[0027] It should be noted here that: through the setting of the driving assembly, it is convenient to expand and deform the adjusting ring 202, so as to form a circular pulling force on the acoustic mesh body 102.

[0028] Please refer to Figure 5 , in the illustrated, the adjusting ring 202, the connecting ring 203 and the driving ring 301 are made of elastic materials;

[0029] It should be noted here that: by making the adjusting ring 202, the connecting ring 203 and the driving ring 301 of elastic materials, when adjusting the relaxation degree of the acoustic mesh body 102, there can be a telescopic movement space.

[0030] Working principle: During the use of the multi-band acoustic mesh body 102, first, it is installed on the inner wall of the adjusting ring 202 by using glue or double-sided tape, and then the fixed ring 101 is installed at the sound outlet position of the speaker. Thus, by using the mesh structure made of the special material of the acoustic mesh body 102, the internal pores can absorb and scatter sound waves, thereby weakening the propagation of noise, and the acoustic mesh body 102 has multi-band performance, so as to provide an effective acoustic filtering effect within different frequency ranges;

[0031] Since the speaker generates vibrations during operation, especially when used at high volume for a long time, the vibrations are more intense. The long-term vibration affects the installation state of the acoustic mesh body 102, which gradually becomes loose. At this time, in order to ensure the use effect of the acoustic mesh body 102, it is necessary to adjust the looseness of the acoustic mesh body 102. During the process of adjusting the looseness of the acoustic mesh body 102, the moving component is used to drive the two pushing rings 302 to move closer to the driving ring 301. When the inclined surfaces 303 on the two pushing rings 302 abut against the inner wall of the driving ring 301, under the mutual acting force, the driving ring 301 will be pushed to expand and deform, further driving one end of the connecting ring 203 to move into the driving cavity 304, thereby driving the adjusting ring 202 to expand and deform, and then performing a circular pulling on the acoustic mesh body 102, reducing the looseness of the acoustic mesh body 102 in the long-term vibration environment. Thus, while ensuring the use performance of the acoustic mesh body 102, the utilization rate of the acoustic mesh body 102 is improved, and further, the replacement frequency of the acoustic mesh body 102 and the use cost of the speaker are reduced.

One end of each of the two moving plates 402 is connected to the pushing ring 302, and the driving cavity 304 is provided with a guiding component for guiding the movement of the two pushing rings 302;

[0034] It should be noted here that: through the setting of the moving component, during the rotation of the double-headed threaded rod 401, under the action of the threaded meshing transmission between the threaded side wall of the double-headed threaded rod 401 and the threaded sleeve 403 and the guiding action of the guiding component, the two pushing rings 302 will be driven to move closer to or away from each other.

[0035] Please refer to Figure 1 , one end of the double-headed threaded rod 401 shown in the figure is flush with the end face of the fixed ring 101, and a regular hexagon rotation hole 404 is provided;

[0036] It should be noted here that: by providing a rotation hole 404 with a regular hexagon shape at one end of the double-headed threaded rod 401, it is convenient to use an internal hexagon wrench to rotate the double-headed threaded rod 401.

[0037] Please refer to Figure 2 andFigure 4 As shown in the figure, the guiding assembly includes a plurality of guiding rods 501 fixedly connected in the driving cavity 304. Both ends of each guiding rod 501 are connected to the opposite inner walls of the driving cavity 304. Two guiding plates 502 are slidably connected to the side walls of each guiding rod 501. One end of the two guiding plates 502 is connected to the pushing ring 302;
