[0002] The eardrum is a key sound-producing component of a loudspeaker, and its quality directly affects the sound quality performance of the loudspeaker. Usually, the eardrum is made of a mixture of cloth, paper, rubber and even metal materials, forming a basin-shaped structure. In the center of the eardrum, a hole is specially designed for mounting a voice coil. The eardrum includes an inner ring and an outer ring. During the manufacturing process, the outer ring needs to be connected to the inner ring. The outer ring serves to fix the inner ring, and the inner ring vibrates and produces sound.

[0003] In the prior art, the installation process of the eardrum usually follows the following steps: first, place the inner ring of the eardrum on the upper surface of the outer ring to ensure that the two are properly aligned. Next, use a hot press to heat the solid glue at the contact part to melt it. In this way, the outer ring and the inner ring can be tightly bonded together, thereby completing the splicing of the eardrum. However, in actual application, when the inner ring or the outer ring of the eardrum is subjected to a rotational force, the bonding part between the two is prone to loosening. This loosening phenomenon can result in insufficient stability of the eardrum product, thereby affecting its overall performance and service life. SUMMARY

[0007] As a preferred technical solution, a plurality of filling layers are arranged between the connecting ring and the collar. The filling layers are used to inject adhesive. An edge sealing ring is further arranged between the collar and the connecting ring. A plurality of filling blocks are arranged on the edge sealing ring, and the filling blocks are embedded in the filling layers.

[0008] Further, a clamping groove is arranged between two adjacent filling blocks. The inner diameter width of the clamping groove is consistent with the width of the mounting block.

[0009] Further, the length ratio of the mounting block to the mounting groove is 1.5 to 1.

[0024] 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.

[0025] In existing technology, during the installation of the diaphragm, the inner ring is first placed on the upper surface of the outer ring. Then, a hot press is used to heat and melt the solid adhesive at the contact points to bond the outer and inner rings, thus completing the diaphragm splicing. However, when the inner or outer ring is subjected to rotational force, they are prone to loosening, which affects the stability of the finished diaphragm.

[0026] Example 1

[0027] Therefore, in order to solve the above problems and improve the connection stability between the inner and outer rings of the diaphragm, this utility model discloses a horn diaphragm, see reference. Figures 1-5 It includes an outer ring 1 and an inner ring 2. The inner ring 2 is located inside the outer ring 1. The outer ring 1 is provided with a collar 11 for fixing the inner ring 2. The inner ring 2 is provided with a connecting ring 6 adapted to the collar 11. The collar 11 has a mounting groove 4 on the side facing the connecting ring 6. The connecting ring 6 is provided with a mounting block 7 adapted to the mounting groove 4.

[0028] In this embodiment, by setting an installation groove 4 and an installation block 7 at the connection between the outer ring 1 and the inner ring 2, the inner ring 2 and the outer ring 1 will not be moved when subjected to rotational force, thereby improving the stability of the finished paper drum.

[0029] In a specific embodiment, during the assembly of the drum paper, the user first places the inner ring 2 into the outer ring 1, and simultaneously aligns the mounting block 7 on the connecting ring 6 with the mounting groove 4 on the collar 11. As the inner ring 2 continues to descend, the bottom of the mounting block 7 will contact the top of the mounting groove 4 until the mounting block 7 is completely inside the mounting groove 4. The four mounting blocks 7 are arranged in a cross shape at the four ends of the connecting ring 6, and the position of the mounting groove 4 on the collar 11 corresponds to the mounting block 7. Therefore, when the mounting block 7 is completely inside the mounting groove 4, it can prevent the inner ring 2 or the outer ring 1 from rotating in the horizontal direction, thereby improving the stability of the finished drum paper.

[0030] It should be noted that the mounting groove 4 and the mounting block 7 are rectangular recesses and rectangular protrusions respectively, due to the stability of the rectangular structure, the inner ring 2 and the outer ring 1 can better withstand the rotating force, ensuring the firmness of the connection. In addition, the rectangular mounting groove 4 and the mounting block 7 are easy to process during manufacturing, reducing production costs.

[0031] In addition, the mounting groove 4 can also adopt a dovetail groove structure to increase the stability of the connection. The dovetail groove structure can provide a larger contact area and friction, thereby forming a tighter fit between the inner ring 2 and the outer ring 1. In practical application, this structure can effectively prevent parts from loosening due to vibration or impact, further improving the durability and reliability of the drum paper. At the same time, the design of the dovetail groove is convenient for installation and disassembly, which facilitates the later maintenance and replacement work.

[0032] In one embodiment, the diameter of the outer ring 1 is 337.35mm.

[0033] Example two

[0034] In combination with example one, after the inner ring 2 is completely placed inside the outer ring 1, it is necessary to fill solid glue between the inner ring 2 and the outer ring 1 to improve the integrity of the inner and outer rings. At present, when filling solid glue, it is usually directly applied on the inner wall of the outer ring 1, and then the inner ring 2 is placed in the outer ring 1 for gluing. This method has certain limitations, for example, uneven glue application may result in uneven bonding strength, or glue overflow during operation may affect the appearance and performance of the drum paper.

[0035] Therefore, in order to solve the above problems, referring to Figure 4 and Figure 5 The utility model also includes a filling layer 12 for pouring adhesive, specifically, a plurality of filling layers 12 are arranged between the connecting ring 6 and the sleeve ring 11, the filling layer 12 is used for pouring adhesive, the sleeve ring 11 and the connecting ring 6 are also provided with an edge sealing ring 3, wherein a plurality of filling blocks 9 are arranged on the edge sealing ring 3, and the filling blocks 9 are embedded in the filling layer 12.

[0036] In this embodiment, after the inner ring 2 is completely placed inside the outer ring 1, the user can place the solid glue along the filling layer 12 between the inner ring 2 and the outer ring 1, then seal the opening of the filling layer 12 by the edge sealing ring 3, and finally melt the solid glue in the filling layer 12 by heating, thereby ensuring that the adhesive is evenly distributed between the inner ring 2 and the outer ring 1, thereby significantly improving the uniformity and overall strength of the bonding. At the same time, due to the arrangement of the filling blocks 9 at the bottom of the edge sealing ring 3, it can help to avoid overflow of the glue in the filling layer 12.

[0037] It needs to be explained that the ratio of the length of the mounting block 7 to the length of the mounting groove 4 is 1.5 to 1, through this setting, after the mounting block 7 is accessed into the mounting groove 4, the mounting block 7 will not enter the mounting groove 4 completely, therefore a gap will be formed between the connecting ring 6 and the sleeve ring 11, at this time, the gap and two adjacent mounting blocks 7 combine to form the filling layer 12, therefore, when the solid glue in the filling layer 12 is melted, the melted glue liquid will fill the gap between the inner ring 2 and the outer ring 1 at the same time, and fill the connecting part of the mounting groove 4 and the mounting block 7, so as to further improve the fixing effect between the outer ring 1 and the inner ring 2.

[0038] In a specific embodiment, after the solid glue is poured into the inside of the filling layer 12, the user needs to align the edge sealing ring 3 with the filling block 9 on one side with the filling layer 12. Then lower the edge sealing ring 3 until the filling block 9 is completely inserted into the inside of the filling layer 12. In this process, since the clamping groove 10 is provided between two adjacent filling blocks 9, and the inner diameter width of the clamping groove 10 is consistent with the width of the mounting block 7. Therefore, the part of the mounting block 7 which does not enter the inside of the mounting groove 4 can be clamped by the clamping groove 10. In this way, the connecting part of the outer ring 1 and the inner ring 2 can be completely closed, so as to achieve the predetermined sealing effect.

[0039] It is worth mentioning that the edge sealing ring 3 is made of rubber material as a whole, so as to improve the flexibility and sealing performance of the edge sealing ring 3, and the rubber material also has the characteristics of aging resistance and corrosion resistance, and can adapt to the use in various environmental conditions.

[0040] Example three

[0041] On the basis of example one and example two, after the outer ring 1 and the inner ring 2 are fixed, the drum paper is connected to the speaker frame, and the external voice coil is connected to the inner ring 2.

[0042] In this embodiment, referring to Figure 2 and Figure 3 The utility model also includes a glue layer 5 and a positioning pipe 8, specifically, the glue layer 5 is arranged in the inside of the outer ring 1, and the glue layer 5 is arranged opposite to the sleeve ring 11, wherein the glue layer 5 is used to connect the speaker frame, the positioning pipe 8 is arranged in the inside of the inner ring 2, and the positioning pipe 8 is arranged opposite to the connecting ring 6, wherein the positioning pipe 8 is arranged in the glue layer 5.

[0043] In the specific embodiment, during the process of fixing the inner ring 2 inside the outer ring 1, the positioning tube 8 needs to be first passed through the adhesive layer 5. Then, the user can apply glue on the bottom of the adhesive layer 5 and the part of the positioning tube 8 that passes through the adhesive layer 5. After the gluing is completed, the part coated with glue is directed towards the inside of the outer basket, and then the inner ring 2 is placed into the outer basket. During this process, it is necessary to ensure that the opening of the positioning tube 8 is directed towards the direction of the voice coil inside the outer basket, so that the voice coil can smoothly pass through the positioning tube 8 and enter the inside of the inner ring 2. In this way, the inner ring 2 can be firmly fixed inside the outer ring 1, while ensuring the correct position and function of the voice coil.

[0044] It is worth mentioning that the inner wall of the inner ring 2 is annularly provided with a plurality of wavy lines, which can absorb and disperse sound vibrations to some extent, thereby improving the sound quality performance of the loudspeaker.

[0045] Further, the outer ring 1 and the inner ring 2 are both conical structures, the arc surface of the outer ring 1 and the sleeve ring 11 are in a stepped shape, and the arc surface of the inner ring 2 and the connecting ring 6 are also in a stepped shape. This arrangement makes the outer ring 1 and the inner ring 2 more stable in structure, and facilitates assembly and disassembly.

[0046] In summary, in combination with Embodiment One to Embodiment Three, the working steps of the loudspeaker drum paper are as follows:

[0047] Firstly, the inner ring 2 is placed into the outer ring 1, ensuring that the mounting block 7 is aligned with the mounting groove 4 and completely enters, then solid glue is filled between the connecting ring 6 and the sleeve ring 11, the filling layer 12 is closed by the edge sealing ring 3 and the filling block 9, and the adhesion is ensured to be uniform and firm. Then, the adhesive layer 5 is used in cooperation with the positioning tube 8 to connect the drum paper to the basket and connect the voice coil. Finally, the wavy lines are arranged to further improve the stability and sound quality performance of the loudspeaker.

[0048] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other.
