[0032] In one embodiment, Figures 1 to 3As shown, a paper basin structure 10 includes: a vibration plate 100 and a folding ring 200; the vibration plate 100 includes a first basin body 110, a first receiving ring 120 and a second receiving ring 130, the first end of the first receiving ring 120 is connected to the first end of the first basin body 110, the second end of the first receiving ring 120 is connected to the first end of the second receiving ring 130, the second end of the first basin body 110 is tilted in a direction away from the center line of the first receiving ring 120, the second end of the second receiving ring 130 is tilted in a direction away from the center line of the first receiving ring 120, and the second receiving ring 130 and the first basin body 110 are arranged on the same side; the folding ring 200 includes a first pressure ring 210, a second pressure ring 220 and a second basin body 230, the first end of the second pressure ring 220 is connected to the second end of the first pressure ring 210 One end is connected, the second end of the second pressure ring 220 is connected to the first end of the second basin body 230, and the second end of the second pressure ring 220 is inclined in the direction away from the center line of the first pressure ring 210; the side of the first receiving ring 120 facing away from the second end of the first basin body 110 is fitted with the side of the first pressure ring 210 facing the second end of the second pressure ring 220, and the side of the second receiving ring 130 facing away from the second end of the first basin body 110 is fitted with the side of the second pressure ring 220 facing the first end of the first pressure ring 210, and the angle between the second pressure ring 220 and the first pressure ring 210 is set to 110°~130°, the angle between the first basin body 110 and the second receiving ring 130 is set to 80°~88°, and the second basin body 230 and the first basin body 110 are spaced apart from each other.

[0033] In this embodiment, the first basin body 110 is used to connect with the skeleton 500, the first basin body 110, the first receiving ring 120 and the second receiving ring 130 are integrally formed, the first basin body 110 and the second receiving ring 130 are arranged in the same direction, the first pressure ring 210, the second pressure ring 220 and the second basin body 230 are integrally formed, the cross-sectional shape of the second basin body 230 is set to be semicircular, the protruding direction of the second basin body 230 is set in the same direction as the position of the first pressure ring 210, the second basin body 230 is used to connect with the bracket 300, the first basin body 110, the first receiving ring 120, the second receiving ring 130, the first pressure ring 210, the second pressure ring 220 and the second basin body 230 are arranged in the same direction, the cross-sectional shape of the second basin body 230 is set to be semicircular, the protruding direction of the second basin body 230 is set in the same direction as the position of the first pressure ring 210, the second basin body 230 is used to connect with the bracket 300, the first basin body 110, the first receiving ring 120, the second receiving ring 130, the first pressure ring 210, the second pressure ring The ring 220 and the second basin 230 are coaxially arranged. The first pressure ring 210 is arranged in contact with the first receiving ring 120, and the second pressure ring 220 is arranged in contact with the second receiving ring 130. This allows the first pressure ring 210 to adhere to the first receiving ring 120, and the second pressure ring 220 to adhere to the second receiving ring 130. This increases the contact area between the folding ring 200 and the vibration plate 100. Furthermore, by adjusting the angle between the second pressure ring 220 and the first pressure ring 210, for example, the angle between the second pressure ring 220 and the first pressure ring 210 is set to 110°. Alternatively, for example, the angle between the second pressure ring 220 and the first pressure ring 210 is set to 130°. Furthermore, by adjusting the angle between the first basin 110 and the second receiving ring 130, for example, the angle between the first basin 110 and the second receiving ring 130 is set to 80°. Alternatively, for example, the angle between the first basin 110 and the second receiving ring 130 is set to 88°. While facilitating the vibration of the folding ring 200 and the vibration plate 100 , the generation of shear stress during vibration is effectively reduced, thereby effectively increasing the rigidity between the folding ring 200 and the vibration plate 100 .

[0034] It is worth noting that the vibration plate 100 is formed by sequentially connecting the first basin 110, the first receiving ring 120 and the second receiving ring 130, and the second receiving ring 130 is arranged toward the same end as the first basin 110, and the folding ring 200 is formed by sequentially connecting the first pressure ring 210, the second pressure ring 220 and the second basin 230, and the first pressure ring 210 and the first receiving ring 120 are arranged in a close relationship, and the second pressure ring 220 and the second receiving ring 130 are arranged in a close relationship, so that the vibration plate 100 is formed. The dynamic plate 100 is connected to the folding ring 200 to form a paper cone structure, and the angle range between the second pressure ring 220 and the first pressure ring 210 is set to 110°~130°, and the angle between the first basin body 110 and the second receiving ring 130 is 80°~88°, thereby improving the rigidity of the vibration plate 100 and the folding ring 200, changing the split movement of the vibration plate 100 and the folding ring 200, thereby improving the acoustic curve of the speaker 20 made of the paper cone, and making the sound of the speaker 20 better.

[0035] It is understandable that if Figure 4As shown, the existing paper cone structure usually sets the cross-sectional shape of the vibration plate 100 to a straight line and the cross-sectional shape of the folding ring 200 to a parabola, which results in poor rigidity during vibration. In order to make the rigidity of the folding ring 200 and the vibration plate 100 stronger, in one embodiment, as shown in FIG. Figure 3 As shown, the angle between the second pressure ring 220 and the first pressure ring 210 is set to 120°, and the angle between the first basin 110 and the second receiving ring 130 is set to 84°. Specifically, by adjusting the installation angle when the vibration plate 100 and the folding ring 200 are connected, the shear stress generated during vibration is effectively reduced, thereby increasing the rigidity of both and reducing the generation of splitting motion, so that the acoustic curve of the speaker 20 made of the paper basin is better. Figure 5 As shown in the figure, it is a frequency response curve of a speaker made of an existing paper cone structure and a speaker made of an improved paper cone structure of this embodiment. Among them, SPL@3w / 0.1m above the figure means that the power during the test is 3W and the distance between the speaker and the test microphone is 0.1m. Figure 5 It can be seen that the acoustic curve of the speaker made of the improved paper cone structure in this embodiment is flatter and its acoustic curve is better, that is, the paper cone structure in this embodiment can effectively increase the rigidity during vibration, thereby making the acoustic curve of the speaker better.

[0036] In order to facilitate the connection between the second pressure ring 220 and the second receiving ring 130, in one embodiment, as shown in FIG. Figure 3 As shown, the second end of the second pressure ring 220 is flush with the second end of the second receiving ring 130. Specifically, while saving material, the second pressure ring 220 and the second receiving ring 130 are ensured to be completely in contact with each other, making the connection between the two more stable and increasing the rigidity of the folding ring 200 and the vibration plate 100 when vibrating with the voice coil 700.

[0037] In order to facilitate the connection between the vibration plate 100 and the voice coil 700, in one embodiment, as shown in FIG. Figure 3 As shown, the second end of the first basin 110 is arranged to protrude from the second end of the second basin 230. Specifically, the second end of the first basin 110 is used to connect to the frame 500. By having the second end of the first basin 110 protrude from the second end of the second basin 230, the voice coil 700 can vibrate with a greater amplitude when driving the vibration plate 100 to vibrate.

[0038] In order to facilitate the connection between the first basin body 110 and the skeleton 500, in one embodiment, as shown in FIG. Figure 2 and Figure 3As shown, a sealing ring 111 is provided at the second end of the first basin 110. Specifically, the sealing ring 111 is used to connect to the frame 500. The connection between the vibration membrane and the frame 500 is more stable through the sealing ring 111.

[0039] In order to enhance the connection strength between the vibration plate 100 and the folding ring 200, in one embodiment, as shown in FIG. Figure 2 and Figure 3 As shown, the sum of the height of the first basin body 110 and the height of the sealing ring 111 is set to twice the height of the second receiving ring 130. Specifically, by setting the height of the second receiving ring 130 to half the sum of the heights of the first basin body 110 and the sealing ring 111, while facilitating the installation of the first basin body 110 and the second receiving ring 130, the contact area between the second receiving ring 130 and the folding ring 200 is increased, effectively increasing the connection strength between the vibration plate 100 and the folding ring 200. It can be understood that the relationship between the sum of the height of the first basin body 110 and the height of the sealing ring 111 and the height of the second receiving ring 130 can be adjusted accordingly according to actual production needs.

[0040] In order to facilitate the installation of the folding ring 200, in one embodiment, as shown in FIG. Figure 2 and Figure 3 As shown, the second end of the second basin body 230 is provided with a mounting ring 231. Specifically, the mounting ring 231 is used to connect with the bracket 300. By providing the mounting ring 231 at the second end of the second basin body 230, the folding ring 200 can be better connected with the bracket 300, thereby facilitating the installation of the folding ring 200. Furthermore, the cross-sectional shape of the mounting ring 231 is set to be L-shaped. Specifically, the mounting ring 231 includes a horizontal mounting portion and a vertical mounting portion. The first end of the horizontal mounting portion is connected to the second end of the second basin body 230, the second end of the horizontal mounting portion is connected to the first end of the vertical mounting portion, the second end of the vertical mounting portion is oriented in the same direction as the protruding direction of the second basin body 230, and the second end of the vertical mounting portion is used to connect with the inner surface of the bracket 300, thereby increasing the contact area between the folding ring 200 and the bracket 300, thereby increasing the connection strength between the two.

[0041] To further stabilize the connection between the folding ring 200 and the vibration plate 100, in one embodiment, a first curved surface is provided at the connection between the first receiving ring 120 and the second receiving ring 130, and a second curved surface is provided at the connection between the first pressure ring 210 and the second pressure ring 220, with the first curved surface and the second curved surface being arranged in close contact with each other. Specifically, by providing a curved surface at the connection between the first receiving ring 120 and the second receiving ring 130, and providing a corresponding curved surface at the connection between the first pressure ring 210 and the second pressure ring 220, when the first curved surface and the second curved surface are in close contact with each other, not only is installation facilitated, but the contact area between the two is also effectively increased, thereby further stabilizing the connection between the folding ring 200 and the vibration plate 100.

[0042] In order to better amplify the sound, in one embodiment, a support rod is provided on the first end of the second basin body, a rotating groove is provided on the support rod, a rotating ring is rotatably provided on the side wall of the rotating groove, and the rotating ring is slidingly connected to the side wall of the rotating groove, a first elastic sound amplifying fan is provided at one end of the rotating ring, and a second elastic sound amplifying fan is provided at the other end of the rotating ring, and the central axis of the first elastic sound amplifying fan is coaxially arranged with the central axis of the second elastic sound amplifying fan, the first elastic sound amplifying fan is protruded toward the first end away from the second basin body, and the cross-sectional shape of the first elastic sound amplifying fan is arc-shaped, the second elastic sound amplifying fan is protruded toward the first end close to the second basin body, and the cross-sectional shape of the second elastic sound amplifying fan is arc-shaped.

[0043] Specifically, the cross-sectional shape of the rotating groove is set to be annular, the material of the first elastic amplifying fan and the second elastic amplifying fan is soft elastic silicone, and the protrusion directions of the first elastic amplifying fan and the second elastic amplifying fan are set differently. When the vibrating ring vibrates, the rotating ring slides up and down along the side wall of the rotating groove under the drive of the support rod and gradually rotates on the support rod due to the vibration of the vibrating ring. When the folding ring vibrates, the rotation of the rotating ring can convert the lateral shear force of the folding ring into a rotational effect on the rotating ring, thereby offsetting a certain amount of the lateral shear force of the folding ring. In this way, the deformation of the folding ring is effectively reduced, thereby reducing the generation of splitting motion. Moreover, when the folding ring vibrates, the first elastic amplifying fan and the second elastic amplifying fan vibrate accordingly. The vibration of the first elastic amplifying fan and the second elastic amplifying fan diffuses the sound waves, thereby enhancing the transmission of the sound waves and improving the sound quality. In addition, by setting the protrusions of the first elastic amplifying fan and the second elastic amplifying fan differently, the sound amplification effect is effectively enhanced. It is understandable that the materials of the support rod, the rotating ring, the first elastic sound amplifying fan and the second elastic sound amplifying fan are relatively light, which can reduce the deformation of the folding ring without increasing the additional deformation of the folding ring.

[0044] Furthermore, a first conical toothed ring is provided on the sidewall of the rotating groove protruding outward, and a second conical toothed ring is provided on the inner surface of the rotating ring, with the top of the first conical toothed ring movably abutting against the bottom of the second conical toothed ring. Specifically, when the folded ring vibrates, the rotating ring slides on the sidewall of the rotating groove and deflects under the action of shear force, causing the first conical toothed ring on the rotating ring to disengage from the second conical toothed ring. The deflection of the rotating ring causes the first conical toothed ring to deflect relative to the original tooth position and slide down the arc surface under the action of gravity, thereby achieving the purpose of advancing one tooth position and abutting against the second conical toothed ring. This reciprocating movement further achieves the purpose of rotating the rotating ring, thereby better rotating the first and second elastic sound amplifying fans. Furthermore, by setting the first and second conical toothed rings to be conical, that is, they are continuous arc surfaces, it is convenient for the first and second conical toothed rings to slide into another tooth position when a small deflection occurs, thereby facilitating the rotation of the rotating ring. It can be understood that the surfaces of the first conical gear ring and the second conical gear ring are highly smooth and have low roughness, so that the second conical gear ring can slide from both sides of the tooth top of the first conical gear ring to the tooth root.

[0045] In one embodiment, Figure 3 、 Figure 6 and Figure 7 As shown, a loudspeaker 20 includes the paper cone structure 10 described in any of the above embodiments, and also includes a bracket 300, a lower magnetic conductive plate 400, a magnet 410, an upper magnetic conductive plate 420, a skeleton 500, a spring 600, a voice coil 700, a dust cap 800 and a terminal; the first end of the bracket 300 is connected to the lower magnetic conductive plate 400 to form a receiving cavity, the magnet 410, the upper magnetic conductive plate 420, the skeleton 500, the spring 600, the voice coil 700 and the dust cap 800 are arranged in the receiving cavity, the first surface of the magnet 410 is connected to the lower magnetic conductive plate 400, the first surface of the upper magnetic conductive plate 420 is connected to the second surface of the magnet 410, the skeleton 500 is slidably arranged on the outside of the magnet 410 and the upper magnetic conductive plate 420, and the The skeleton 500 is spaced from the magnet 410 and the upper magnetic conductive plate 420, the voice coil 700 is sleeved on the outer surface of the skeleton 500, the elastic wave 600 is connected to the end of the voice coil 700 away from the lower magnetic conductive plate 400, the second end of the first basin 110 is connected to the skeleton 500, and the second end of the first basin 110 is located on the side of the elastic wave 600 away from the lower magnetic conductive plate 400, the second end of the second basin 230 is connected to the second end of the bracket 300, the dust cap 800 is arranged on the end of the skeleton 500 away from the lower magnetic conductive plate 400, the terminal is arranged on the outer surface of the bracket 300, and the terminal is electrically connected to the voice coil 700 by passing through the through hole opened on the bracket 300 through the silk thread.

[0046] Specifically, the bottom of the bracket 300 is connected to the lower magnetic conductive plate 400 so that the inner surface of the bracket 300 and the top surface of the lower magnetic conductive plate 400 form a accommodating cavity, the magnet 410 and the upper magnetic conductive plate 420 are arranged on the lower magnetic conductive plate 400 in sequence, and then one end of the skeleton 500 is sleeved on the outer surface of the magnet 410 and the upper magnetic conductive plate 420, and the voice coil 700 is wound and set on the skeleton 500, and then the elastic wave 600 is connected to the voice coil 700, the skeleton 500 is connected to the vibration plate 100, the vibration plate 100 is connected to the folding ring 200, and the folding ring 200 is connected to the bracket 300. Finally, the terminal is electrically connected to the voice coil 700 by passing the silk thread through the through hole opened on the bracket. Thus, by applying power to the voice coil 700 to generate a magnetic field, the magnetic fields of the magnet 410, upper magnetic plate 420, and lower magnetic plate 400 exert a force on the voice coil, causing the coil to move up and down. This, in turn, causes the bobbin 500, which is fixed to the coil, to drive the damper 600, diaphragm 100, and surround 200 to move up and down. The vibrations of the damper 600, diaphragm 100, and surround 200 produce sound. By connecting the first pressure ring 210 and the first receiving ring 120, and the second pressure ring 220 and the second receiving ring 130, the vibration plate 100 and the folding ring 200 are connected to form a paper cone, and the angle range of the second pressure ring 220 and the second receiving ring 130 is set to 110°~130°, and the angle between the first basin body 110 and the second receiving ring 130 is 80°~88°, thereby improving the rigidity of the vibration plate 100 and the folding ring 200, reducing the deformation of the vibration plate 100 and the folding ring 200, that is, improving the splitting movement of the vibration plate 100 and the folding ring 200, and then improving the acoustic curve of the speaker 20 made of the paper cone, so that the sound of the speaker 20 is better.
