Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a clamping plate for loudspeakers. Background Art

[0002] A loudspeaker is a transducer device that converts electrical signals into acoustic signals. A typical speaker consists of a clamping plate, a magnet, a frame, a centering support, and a molded, folded-ring cone. The clamping plate may include an upper clamping plate and a lower clamping plate, with the magnet positioned on the lower clamping plate and held in place by the upper clamping plate. Speaker heating is caused by the thermal effects of current passing through the voice coil. Existing technologies incorporate heat dissipation channels in the lower clamping plate to dissipate heat through convection, but this method is ineffective. Therefore, a more efficient speaker clamping plate is needed to address the problem of speaker overheating.

[0003] An existing patent (publication number: CN216531783U) discloses a speaker clamp. The heat dissipation holes dissipate heat through convection, and the heat dissipation assembly transfers heat from the upper and lower clamps to the speaker housing through heat conduction. This combination of convection and conduction improves the speaker's heat dissipation efficiency. During the implementation of this solution, the following problems were discovered in the prior art that have not been adequately addressed:

[0004] The heat conducting sheet is a fixed structure during use and cannot be flexibly adjusted according to the splint. In addition, the heat conducting sheet is prone to blocking the heat dissipation vents during use. Heat dissipation itself is caused by air circulation, which can easily affect the heat dissipation effect. In addition, impurities can easily remain inside the heat dissipation vents, affecting use. Utility Model Content

[0005] In order to improve the above-mentioned problem that the heat conducting sheet cannot be flexibly adjusted, which easily affects the air circulation, and dust stays inside the heat dissipation slot and is tedious to clean, the utility model provides a clamping plate for a speaker.

[0006] The utility model provides a splint for a loudspeaker, which adopts the following technical solutions:

[0007] A speaker clamping plate comprises a mounting post and a mounting block, an upper clamping plate is provided above the mounting post, a heat dissipation groove is provided on the inner side of the upper clamping plate, a filter is connected to the center of the heat dissipation groove, a fixing rod is connected to the outer side of the filter, a heat conducting plate is connected to the other side of the fixing rod, a connecting rod is connected to the outer side of the heat conducting plate, and an anti-drop block is connected to the outer side of the connecting rod;

[0008] The inner side of the mounting block is connected with a screw thread, the inner side of the screw thread is also connected with a heat absorbing plate, the inner side of the heat absorbing plate is connected with a center block, and both sides of the center block are connected with return springs.

[0009] Through the above technical solution, it is convenient to cooperate with the heat absorbing plate through the mounting block, so that the heat conducting plate can be adjusted up and down to ensure that it is suitable for use with different splints. A detachable filter is provided on the inner side of the heat conducting plate to prevent dust from staying inside the heat dissipation slot, and the air circulation is not affected by the connecting rod, thereby ensuring that the heat dissipation work is carried out.

[0010] Optionally, in the above-mentioned speaker clamping plate, heat dissipation grooves are evenly and equidistantly distributed around the center of the upper clamping plate, the size of the heat dissipation grooves is consistent with the size of the filter screen, and the filter screen is connected to the heat dissipation grooves by a sliding connection.

[0011] The above technical solution facilitates isolating the inside and outside of the heat sink through the filter, thereby preventing dust from circulating inside and outside.

[0012] Optionally, in the above-mentioned speaker clamp, connecting rods are evenly and equidistantly distributed on the outer side of the heat conducting plate, the connecting rods are integrated with the anti-detachment block, and the anti-detachment block fits tightly against the inner side of the heat dissipation groove.

[0013] The above technical solution facilitates heat dissipation by cooperating with the heat conducting sheet and the connecting rod without affecting air circulation.

[0014] Optionally, in the above-mentioned speaker clamp, the heat absorbing sheet is connected to the screw nail by threaded connection, the screw nail is connected to the mounting block by threaded connection, and the heat absorbing sheet is evenly and equidistantly distributed on the inner side of the mounting block.

[0015] The above technical solution facilitates connecting the heat absorbing plate and the mounting block through screws, and facilitates replacing the heat absorbing plate separately for maintenance.

[0016] Optionally, in the above-mentioned speaker splint, return springs are symmetrically distributed on both sides of the center block, the center block forms a spring return structure through the return spring and the heat conducting plate, and the connection between the heat conducting plate and the heat absorbing plate is a sliding connection.

[0017] Through the above technical solution, it is convenient to drive the heat absorbing plate to move through the reset spring, ensuring that it can adapt to different splints.

[0018] Optionally, in the above-mentioned speaker clamping plate, keels are evenly and equidistantly distributed on the inner side of the filter, and the keels are installed in an integrated manner with the fixing rod, and the connection between the fixing rod and the heat conducting plate is a threaded connection.

[0019] The above technical solution makes it easy to disassemble the filter screen and clean it by cooperating with the fixing rod.

[0020] In summary, the present invention has at least one of the following beneficial effects:

[0021] By arranging a connecting rod and an anti-drop block on the inner side of the heat conducting sheet, the heat conducting sheet is clamped inside the heat sink, which can absorb and discharge the heat inside the heat sink without affecting the air circulation and ensuring the cooling effect. A detachable filter is also arranged on the inner side of the heat conducting sheet, which is easy to clean and replace, and prevents dust from being displaced inside and outside the heat sink through the heat sink, affecting the use.

[0022] By arranging a heat absorbing plate in the center of the heat conducting plate and cooperating with a return spring, the heat absorbing plate can use the return spring to change the height of the heat conducting plate to adapt to the upper and lower clamping plates with different spacings, and the heat absorbing plate itself is fixed with screw nails and mounting blocks. When the return spring or the heat absorbing plate is damaged, it can be replaced and repaired separately without replacing the entire plate. It is easy to use and has a simple structure.

[0028] The following is combined with Figure 1-4 The utility model is described in further detail.

[0029] Please refer to the attached figure in the instruction manual Figure 1-4The utility model provides an embodiment: a speaker clamping plate, including a mounting column 1 and a mounting block 8, an upper clamping plate 2 is provided above the mounting column 1, and a heat dissipation groove 3 is provided on the inner side of the upper clamping plate 2. Heat is dissipated through the heat dissipation groove 3 to prevent excessive temperature from affecting the use of the speaker. A filter screen 13 is connected to the center of the heat dissipation groove 3, and a fixing rod 12 is connected to the outer side of the filter screen 13. The fixing rod 12 is used to remove the filter screen 13, which is convenient for cleaning or replacing the filter screen 13. A heat conducting sheet 4 is connected to the other side of the fixing rod 12, and a connecting rod 10 is connected to the outer side of the heat conducting sheet 4. The connecting rod 10 does not affect air circulation and improves the heat dissipation effect. An anti-slip block 11 is connected to the outer side of the connecting rod 10. The anti-slip block 11 increases friction to prevent the heat conducting sheet 4 from falling off the heat dissipation groove 3.

[0030] The inner side of the mounting block 8 is connected with a threaded nail 9, which connects the mounting block 8 and the heat absorbing sheet 5 through the threaded nail 9, which facilitates the separate removal of the heat absorbing sheet 5. The inner side of the threaded nail 9 is also connected with a heat absorbing sheet 5, which transfers the heat of the heat conducting sheet 4 through the heat absorbing sheet 5 to improve the heat dissipation effect. The inner side of the heat absorbing sheet 5 is connected with a center block 7, which cooperates with the return spring 6 to ensure the adjustment of the position of the heat conducting sheet 4. Return springs 6 are connected to both sides of the center block 7.

[0031] See the attached drawings in the specification Figure 1-4 There are heat dissipation slots 3 evenly distributed around the center of the upper splint 2. The size of the heat dissipation slots 3 is consistent with the size of the filter 13. The filter 13 is connected to the heat dissipation slot 3 by a sliding connection. The filter 13 isolates the inside and outside of the heat dissipation slot 3 to prevent dust from circulating inside and outside.

[0032] See the attached drawings in the specification Figure 1-4 Connecting rods 10 are evenly and equidistantly distributed on the outside of the heat conducting sheet 4. The connecting rods 10 and the anti-slip blocks 11 are installed in an integrated manner. The anti-slip blocks 11 fit tightly against the inner side of the heat dissipation slot 3. The heat conducting sheet 4 cooperates with the connecting rods 10 to perform heat dissipation without affecting air circulation.

[0033] See the attached drawings in the specification Figure 1-4 The heat absorbing sheet 5 is connected to the threaded nail 9 by a threaded connection, and the threaded nail 9 is connected to the mounting block 8 by a threaded connection. The heat absorbing sheet 5 is evenly and equidistantly distributed on the inner side of the mounting block 8. The heat absorbing sheet 5 and the mounting block 8 are connected by the threaded nail 9, which makes it convenient to replace the heat absorbing sheet 5 separately for maintenance.

[0034] See the attached drawings in the specification Figure 1-4 There are return springs 6 symmetrically distributed on both sides of the center block 7. The center block 7 forms a spring return structure with the heat conducting plate 4 through the return spring 6. The connection between the heat conducting plate 4 and the heat absorbing plate 5 is a sliding connection. The heat absorbing plate 5 is driven by the return spring 6 to move, ensuring that it can adapt to different splints.

[0035] See the attached drawings in the specification Figure 1-4 There are keels evenly and equidistantly distributed on the inner side of the filter screen 13, and the keels are integrated with the fixing rod 12. The connection between the fixing rod 12 and the heat conducting plate 4 is a threaded connection. The filter screen 13 cooperates with the fixing rod 12 to disassemble the filter screen 13 and clean the filter screen 13.

[0036] Working principle: When in use, first, during the heat dissipation process, the air inside the upper clamping plate 2 is replaced with the external air through the heat dissipation groove 3, thereby performing heat dissipation work. At the same time, part of the heat in the heat dissipation process is absorbed by the heat conducting sheet 4, and the heat conducting sheet 4 is located on the inner side of the heat absorbing sheet 5. The heat is transferred to the heat absorbing sheet 5 and finally discharged to the outer shell by the mounting block 8 to perform auxiliary heat dissipation work. At the same time, during the air replacement process, the debris in the air is blocked by the filter 13, and there will be no internal and external interaction.

[0037] As mentioned above, during the maintenance process, the center threaded nail 9 of the heat absorbing plate 5 that needs to be repaired is unscrewed, the mounting block 8 and the heat absorbing plate 5 drive the fixed limit, and then the heat conducting plate 4 is pulled outward so that it drives the anti-slip block 11 and the filter screen 13 to separate from the upper clamping plate 2, and then the connection with the lower clamping plate is released in the same way, and the heat conducting plate 4 is repaired. At the same time, the filter screen 13 is screwed so that the fixing rod 12 and the heat conducting plate 4 are threaded, and the filter screen 13 is disassembled for cleaning and maintenance. During installation, because the heat conducting plate 4 forms a reset structure with the center block 7 through the reset spring 6, it can adapt to clamping plates of different spacings. At the same time, the friction between the anti-slip block 11 and the clamping plate is large, preventing the heat conducting plate 4 from being disconnected.

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
