Description

Technical Field

[0001] The utility model relates to a loudspeaker, in particular to a paper cone structure of the loudspeaker. Background Art

[0002] The working principle of a loudspeaker is that an electrical signal drives the voice coil to vibrate in a magnetic field, which in turn drives the cone to vibrate, pushing air to produce sound. To achieve better sound quality, a folding ring connects the cone to the frame, ensuring that the cone vibrates primarily along the axial direction, ensuring consistent vibration direction, thereby improving the directivity and clarity of the sound. Because the folding ring and cone are typically connected using adhesive bonding, either front-facing or back-facing, prolonged use of the speaker can cause vibration to cause the cone and folding ring to debond, resulting in sound distortion. Utility Model Content

[0003] The purpose of the utility model is to provide a paper cone structure for a loudspeaker, and the technical problem to be solved is how to improve the durability of the connection between the cone and the folding ring.

[0004] The utility model is achieved through the following technical solutions:

[0005] The speaker's paper cone structure includes a cone and a folding ring, the folding ring is used to connect the cone and the basin frame; the folding ring is an overlapping double-layer structure;

[0006] The double-layer structure comprises an upper ring and a lower ring, the middle parts of the upper ring and the lower ring are connected, and a gap is left between the inner circumference of the upper ring and the inner circumference of the lower ring, and the gap is used to insert the edge of the cone.

[0007] Compared with the single-layer structure, the double-layer folding ring structure has higher rigidity and strength, and can more effectively resist deformation and displacement during vibration, thereby ensuring that the connection between the cone and the folding ring is more stable and reliable; after the edge of the cone is inserted into the gap between the inner circumference of the upper ring and the inner circumference of the lower ring, the connection between the cone and the folding ring is realized. Since the loudspeaker mainly vibrates in the axial direction, the cone and the folding ring connected by this plug-in method need to be subjected to force in the radial direction to achieve loading and unloading. Therefore, even if the loudspeaker vibrates for a long time, the impact on the connection between the cone and the folding ring is minimal, thereby improving the durability of the connection between the cone and the folding ring; the stable connection structure helps to reduce nonlinear distortion during vibration and ensure that the sound signal can be transmitted accurately and truthfully, which is of great significance to improving the sound quality and clarity of the loudspeaker.

[0008] Furthermore, protrusions are arranged around the circumference of the folded ring;

[0009] The gap between the inner circumference of the upper ring and the inner circumference of the lower ring is set beside the protrusion;

[0010] When the edge of the cone is inserted into the gap, the end of the cone inserted into the gap abuts against the protrusion.

[0011] When the edge of the cone is inserted into the gap, the end of the cone abuts against the protrusion. This abutment not only provides additional physical support, but also increases the locking effect of the connection point, preventing the cone from slipping or loosening during vibration; the close contact between the protrusion and the edge of the cone makes the connection more secure and able to withstand greater vibration force and stress, thereby improving the durability of the connection; the protrusion absorbs and disperses energy during vibration, reduces the concentration of energy at the connection point, reduces fatigue damage to the connection components, and extends the service life.

[0012] Furthermore, at least two protrusions are provided along the radial direction of the fold ring.

[0013] The distribution of multiple protrusions ensures that stress is more evenly dispersed in the connection area. When the cone vibrates, the stress generated is shared by these protrusions, avoiding excessive concentration of stress in a single location, thereby reducing the risk of fatigue damage. More uniform stress distribution means that the connecting components can withstand vibration for longer periods of time without being easily damaged, thereby improving the overall durability of the speaker.

[0014] Furthermore, the protrusion is arranged in a direction away from the cone;

[0015] When the edge of the cone is inserted into the gap, the end of the cone inserted into the gap abuts against the protrusion of the lower ring.

[0016] This gap forms an annular retaining feature. When the cone edge fits into the gap and abuts the protrusion, radial positioning is achieved, preventing the cone from slipping or falling out during axial vibration. The outward-facing protrusion also increases the surround's resistance to external physical impact and deformation. This protrusion design better protects the connection point from damage, extending the speaker's lifespan, as speakers may be subjected to various external forces during transportation, installation, or use.

[0017] Furthermore, a gap is left between the outer circumference of the upper ring and the outer circumference of the lower ring, and the gap is used to insert the edge of the basin frame;

[0018] When the edge of the basin frame is inserted into the gap, the end of the basin frame inserted into the gap abuts against the protrusion of the lower ring.

[0019] The basin frame and the surround are connected by plug-in, and radial force is required to achieve the installation and removal of the basin frame and the surround. When the speaker vibrates axially, the impact on the connection between the basin frame and the surround is minimal, thereby improving the durability of the connection between the basin frame and the surround.

[0020] Furthermore, an adhesive layer is provided on the lower surface of the upper ring and the upper surface of the lower ring, and the adhesive layer is used to bond the cone basin and the edge of the basin frame.

[0021] In addition to the previous mechanical locking (such as the edge of the cone and the edge of the basin frame are inserted into the folding ring, and the end of the cone and the end of the basin frame abut the protrusion), the addition of the adhesive layer provides another bonding mechanism. The dual mechanism makes the connection stronger and can maintain the stability of the connection even under vibration or external impact; the adhesive layer not only enhances the strength of the connection, but also improves the sealing of the connection, fills any tiny gaps that may exist, prevents air leakage and sound distortion, and improves the sound quality and efficiency of the speaker.

[0022] Furthermore, the folded ring gradually tilts toward the cone from the protrusion to the inner circumference; and the slope gradually increases from the protrusion to the inner circumference.

[0023] In order to reduce sound distortion, the radiating surface of the cone is usually set to be arc-shaped, and the end of the radiating surface is connected to the folding ring. In order to improve the assembly effect between the cone and the folding ring, the folding ring part that fits the cone is also set to be arc-shaped, which not only facilitates assembly but also plays a certain locking role.

[0024] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0025] Compared with the single-layer structure, the double-layer folding ring structure has higher rigidity and strength, and can more effectively resist deformation and displacement during vibration, thereby ensuring that the connection between the cone and the folding ring is more stable and reliable; after the edge of the cone is inserted into the gap between the inner circumference of the upper ring and the inner circumference of the lower ring, the connection between the cone and the folding ring is realized. Since the loudspeaker mainly vibrates in the axial direction, the cone and the folding ring connected by this plug-in method need to be subjected to force in the radial direction to achieve loading and unloading. Therefore, even if the loudspeaker vibrates for a long time, the impact on the connection between the cone and the folding ring is minimal, thereby improving the durability of the connection between the cone and the folding ring; the stable connection structure helps to reduce nonlinear distortion during vibration and ensure that the sound signal can be transmitted accurately and truthfully, which is of great significance to improving the sound quality and clarity of the loudspeaker.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0033] Example 1

[0034] Combine Figure 1 and Figure 2 The present embodiment 1 provides a paper cone structure of a speaker, comprising a cone 10 and a folding ring 20, wherein the folding ring 20 is used to connect the cone 10 and the basin frame; the folding ring 20 is an overlapping double-layer structure;

[0035] The above-mentioned double-layer structure includes an upper ring 21 and a lower ring 22. The middle parts of the upper ring 21 and the lower ring 22 are connected. This connection method can be achieved by one-piece molding using a viscose hot pressing process, or the middle part can be molded as a whole during the plastic process, leaving a gap at the edge; a gap is left between the inner circumference of the upper ring 21 and the inner circumference of the lower ring 22, and the gap is used to insert the edge of the cone basin 10; a gap is left between the outer circumference of the upper ring 21 and the outer circumference of the lower ring 22, and the gap is used to insert the edge of the basin frame.

[0036] Compared with the single-layer structure, the double-layer folding ring 20 structure has higher rigidity and strength, and can more effectively resist deformation and displacement during vibration, thereby ensuring that the connection between the cone 10 and the folding ring 20 is more stable and reliable; after the edge of the cone 10 is inserted into the gap between the inner circumference of the upper ring 21 and the inner circumference of the lower ring 22, the connection between the cone 10 and the folding ring 20 is realized. Since the loudspeaker mainly vibrates in the axial direction, the cone 10 and the folding ring 20 connected by this plug-in method need to be subjected to force in the radial direction to achieve loading and unloading. Therefore, even if the loudspeaker vibrates for a long time, the impact on the connection between the cone 10 and the folding ring 20 is minimal, thereby improving the durability of the connection between the cone 10 and the folding ring 20; the stable connection structure helps to reduce nonlinear distortion during vibration and ensure that the sound signal can be transmitted accurately and truthfully, which is of great significance for improving the sound quality and clarity of the loudspeaker.

[0037] The double-layer structure can better control the vibration behavior of the cone 10, reduce the interference of unnecessary vibration modes on the low-frequency response, and improve the low-frequency response characteristics of the speaker to a certain extent, making the low-frequency sound fuller and more powerful.

[0038] Example 2

[0039] On the basis of Example 1, combined Figure 3 , protrusions 23 are arranged around the circumference of the folding ring 20;

[0040] The gap between the inner circumference of the upper ring 21 and the inner circumference of the lower ring 22 is set beside the protrusion 23;

[0041] When the edge of the cone 10 is inserted into the gap, the end of the cone 10 inserted into the gap abuts against the protrusion 23 .

[0042] When the edge of the cone 10 is inserted into the gap, the end of the cone 10 abuts against the protrusion 23. This abutment not only provides additional physical support, but also increases the locking effect of the connection point, preventing the cone 10 from slipping or loosening during vibration; the close contact between the protrusion 23 and the edge of the cone 10 makes the connection more secure and able to withstand greater vibration force and stress, thereby improving the durability of the connection; the protrusion 23 absorbs and disperses energy during vibration, reduces the concentration of energy at the connection point, reduces fatigue damage to the connection components, and extends the service life.

[0043] In a specific embodiment, at least two protrusions 23 are provided along the radial direction of the fold ring 20 .

[0044] The distribution of multiple protrusions 23 allows stress to be more evenly dispersed in the connection area; when the cone 10 vibrates, the generated stress is shared by these protrusions 23, avoiding excessive concentration of stress in a single location, thereby reducing the risk of fatigue damage; more uniform stress distribution means that the connecting components can withstand vibration for longer periods of time without being easily damaged, thereby improving the overall durability of the speaker.

[0045] An application scenario for reference is to set a protrusion 231 and a protrusion 232 in the radial direction of the folding ring 20, with the protrusion 231 close to the inner circumference of the folding ring 20 and the protrusion 232 close to the outer circumference of the folding ring 20. After the edge of the above-mentioned cone basin 10 is inserted into the inner circumference of the folding ring 20, the end of the cone basin 10 abuts against the protrusion 231. After the edge of the above-mentioned basin frame is inserted into the outer circumference of the folding ring 20, the end of the basin frame abuts against the protrusion 232.

[0046] Example 3

[0047] Based on Example 2, the protrusion 23 can be arranged either toward the cone 10 or away from the cone 10. Considering that the speaker is susceptible to external physical impact in actual use, the protrusion 23 is arranged away from the cone 10 in this embodiment.

[0048] When the edge of the cone 10 is inserted into the inner circumference of the fold 20, the end of the cone 10 inserted into the inner circumference of the fold 20 abuts against the protrusion 23 of the lower ring 22; at this time, the protrusion 23 of the upper ring 21 is located on the upper surface of the end of the cone 10;

[0049] When the edge of the basin frame is inserted into the outer circumference of the fold ring 20, the end of the basin frame inserted into the outer circumference of the fold ring 20 abuts against the protrusion 23 of the lower ring 22; at this time, the protrusion 23 of the upper ring 21 is located on the upper surface of the basin frame end.

[0050] The cone 10, the basin frame and the folding ring 20 are connected by plugging, and radial force is required to achieve assembly and disassembly. When the speaker vibrates axially, the effect on the plugging is minimal, thereby improving the durability of the connection between the cone 10 and the folding ring 20, and the basin frame and the folding ring 20.

[0051] The gap forms an annular stop. When the edge of the cone 10 and the frame are inserted into the gap and abut against the protrusion 23, radial positioning is achieved, preventing any slippage or dislodging of the cone 10 and frame during axial vibration. The outward orientation of the protrusion 23 also increases the surround 20's resistance to external physical impact and deformation. During transportation, installation, or use, speakers may be subjected to various external forces. This design of the protrusion 23 better protects the connection points from damage, extending the speaker's service life.

[0052] While the primary purpose of the protrusions 23 is to enhance the connection, their outward position may also have a positive effect on airflow control; when the loudspeaker is operating, air flows through the gap between the surround 20 and the cone 10, and the protrusions 23 help guide the airflow through more smoothly, reducing the formation of turbulence and vortices, thereby improving the acoustic performance of the loudspeaker.

[0053] Example 4

[0054] On the basis of Example 3, the lower surface of the upper ring 21 and the upper surface of the lower ring 22 are both provided with an adhesive layer, and the adhesive layer is used to bond the cone 10 and the edge of the basin frame.

[0055] In addition to the previous mechanical locking (such as the edge of the cone 10 and the edge of the basin frame are inserted into the folding ring 20, and the end of the cone 10 and the end of the basin frame abut against the protrusion 23), the addition of the adhesive layer provides another bonding mechanism. The dual mechanism makes the connection more secure and can maintain the stability of the connection even under vibration or external impact; the adhesive layer not only enhances the strength of the connection, but also improves the sealing of the connection, fills any tiny gaps that may exist, prevents air leakage and sound distortion, and improves the sound quality and efficiency of the speaker.

[0056] The above-mentioned adhesive layer can be evenly distributed on the connecting surface, so that the stress can be better dispersed during the transmission process, which helps to reduce stress concentration and reduce the risk of damage to components due to fatigue; through the bonding effect of the adhesive layer, the cone 10, the folding ring 20 and the basin frame form a tighter overall structure, which can better resist deformation and damage during vibration, thereby improving the overall strength and durability of the speaker; during assembly, it is only necessary to align the edges of the cone 10 and the basin frame and press them into the gap of the folding ring 20, and then use the bonding force of the adhesive layer to firmly connect them together, reducing the number of fasteners and tools required in the assembly process and improving assembly efficiency.

[0057] Example 5

[0058] On the basis of Example 2, the fold ring 20 gradually tilts toward the cone 10 from the protrusion 23 to the inner circumference; the slope gradually increases from the protrusion 23 to the inner circumference.

[0059] In order to reduce sound distortion, the cone 10 usually has an arc-shaped radiation surface, and the end of the radiation surface is connected to the folding ring 20. In order to improve the assembly effect between the cone 10 and the folding ring 20, the part of the folding ring 20 that fits the cone 10 is also set to be arc-shaped, which not only facilitates assembly but also plays a certain locking role.

[0060] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
