Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] (First embodiment) Figure 1 This is a perspective view of the loudspeaker provided by the present invention. Figure 2 The exploded view shown is a disassembled view of the loudspeaker according to the first embodiment of the present invention. This embodiment provides a loudspeaker 100, including: a frame 1, a vibration system 2 and a magnetic circuit system 3, wherein the magnetic circuit system 3 drives the vibration system 2 to vibrate and produce sound.

[0026] The vibration system 2 is fixed to the frame 1. The vibration system 2 includes a diaphragm 21 fixed to the frame 1 and a voice coil 22 that drives the diaphragm 21 to vibrate and produce sound. The diaphragm 21 includes a dome 211 and a folded ring 212 surrounding the dome 211. The folded ring 212 includes an outer fixed part 2121 fixed to the frame 1, an inner fixed part 2122 fixedly connected to the dome 211, and a first deformation part 2123 connecting the outer fixed part 2121 and the inner fixed part 2122. When the diaphragm 21 vibrates and produces sound, the first deformation part 2123 can deform.

[0027] The loudspeaker 100 also includes a damping element 4. In the first embodiment, the damping element 4 is fixedly attached to the first deformation part 2123. When the diaphragm 21 vibrates to produce sound, the first deformation part 2123 deforms and causes the damping element 4 to deform. The damping element 4 is used to increase the vibration damping of the diaphragm 21.

[0028] By attaching and fixing the damping element 4 to the first deformable part 2123 of the surround 212, the damping coefficient of the surround 212 is increased, thereby increasing the vibration damping of the speaker diaphragm 21, reducing distortion, and making the sound closer to the purity of the original signal. At the same time, the damping element 4 can limit the vibration amplitude of the diaphragm 21, suppress the nonlinear vibration of the diaphragm 21, optimize the low-frequency response, and reduce the risk of damage to the diaphragm 21 due to excessive vibration caused by mechanical resonance or unnecessary vibration, thereby improving the reliability of the vibration system 2 and extending the service life of the speaker.

[0029] In the first embodiment, the folded ring 212 protrudes towards the inside of the speaker, with its opening facing outwards. The damping member 4 is attached to the side of the first deformable portion 2123 facing inwards from the speaker. It should be noted that the damping member 4 can also be attached to the side of the first deformable portion 2123 away from the inside of the speaker. Of course, the folded ring 212 can also protrude towards the outside of the speaker, with the damping member 4 attached and fixed to the side of the first deformable portion 2123 facing inwards from the speaker. As long as the damping member 4 is attached and fixed to the first deformable portion 2123, it is sufficient.

[0030] Furthermore, there are two damping elements 4, which are respectively arranged on opposite sides of the voice coil 22 along a first direction perpendicular to the vibration direction of the diaphragm 21. This arrangement can balance the weight at both ends of the diaphragm 21 in the first direction, making the amplitude of the diaphragm 21 consistent at both ends and improving the acoustic stability of the loudspeaker.

[0031] Preferably, the damping element 4 is a damping adhesive made of a polymer material. The damping adhesive made of polymer material has viscoelasticity, which can absorb redundant vibrations during vibration and has a good suppression effect on both high-frequency and low-frequency resonances. At the same time, due to its light weight, it will not impose a weight burden on the vibration system 2. Furthermore, more preferably, a damping adhesive with good adhesion properties can be used, so that the damping element 4 can be firmly adhered to the surface of components such as the first deformation part 2123, forming a uniform internal damping layer, effectively avoiding stress concentration and reducing the risk of failure due to the damping element 4 detaching.

[0032] Figure 3 The loudspeaker along the first embodiment of the present invention Figure 1 Cross-sectional view of line AA in the middle. Figure 4 The loudspeaker in the first embodiment of the present invention Figure 3 A magnified view of the area at position C, as shown below. Figure 3-4As shown, the dome 211 includes a flat plate portion 2111 and an extension portion 2112 that bends and extends from the outer edge of the flat plate portion 2111 in a direction away from the flat plate portion 2111. The extension portion 2112 is spaced apart from the frame 1. It should be noted that in some other embodiments, the vibration system 2 includes a frame fixed to the diaphragm 21, wherein the frame or a portion of the frame acts as the dome 211.

[0033] Preferably, the damping element 4 is also fixedly connected to the extension 2112 and the frame 1. When the voice coil 22 drives the diaphragm 21 to vibrate and produce sound, the frame 1 is relatively stationary. The damping element 4 is fixed to the frame 1, which firstly allows for more full utilization of the internal resistance of the damping element 4 during deformation to achieve the damping effect; secondly, it makes the fixation of the damping element 4 more secure, reducing the burden of the weight of the damping element 4 on the folding ring 212; and finally, the damping element 4 can reduce the transmission of vibration energy to the frame 1, suppressing the resonance of the frame 1. In addition, fixing the damping element 4 to the extension 2112 of the dome 211 can limit the excessive vibration of the dome 211 during high-frequency vibration, improving high-frequency distortion. At the same time, the damping element 4 is simultaneously connected to the first deformation part 2123 of the folding ring 212, the frame 1, and the extension 2112, forming a "three-sided fixed" structure, which can more evenly distribute vibration energy and enhance the stability of the structure. It also expands the damping range, reduces resonance coupling, and improves acoustic distortion.

[0034] In the first embodiment of the present invention, the vibration system 2 further includes a flexible support member 23 for supplying power to the voice coil 22. The flexible support member 23 includes an outer fixed portion 231 fixed to the frame 1, a second deformation portion 233 extending from the outer fixed portion 231 toward the voice coil 22, and an inner fixed portion 232 extending from the second deformation portion 233 and connected to the diaphragm 21 or the voice coil 22. When the diaphragm 21 vibrates to produce sound, the second deformation portion 233 can deform. The flexible support member 23 effectively suppresses the lateral sway of the voice coil 22, improving the reliability and stability of the loudspeaker.

[0035] In the first embodiment of the present invention, the vibration system 2 further includes an auxiliary diaphragm 24 fixed to the flexible support 23 on the side opposite to the diaphragm 21. Optionally, there are two auxiliary diaphragms 24, which are symmetrically arranged. The auxiliary diaphragm 24 includes a third deformation portion 241, which deforms when the diaphragm 21 vibrates to produce sound. The function of the auxiliary diaphragm 24 is to enhance the linear response of the vibration system 2 and improve the sound quality.

[0036] Furthermore, the magnetic circuit system 3 is fixed to the frame 1 and drives the vibration system 2 to vibrate and produce sound; the magnetic circuit system 3 includes a lower clamping plate 31, a central magnetic circuit 32 fixed to the lower clamping plate 31, and a side magnetic circuit 34 arranged around the central magnetic circuit 32 to form a magnetic gap 33. The lower clamping plate 31 is provided with a clearance groove 311 to avoid the voice coil 22. The voice coil 22 is inserted into the magnetic gap 33. After being energized, the voice coil 22 interacts with the magnetic circuit system 3, driving the diaphragm 21 to vibrate and produce sound.

[0037] Furthermore, such as Figure 3 As shown, the diaphragm 21 also includes an inner folded ring 213. The dome 211 surrounds the outer side of the inner folded ring 213 and connects the folded ring 212 and the inner folded ring 213. The inner folded ring 213 includes an outer fixing part 2131 fixedly connected to the dome 211, an inner fixing part 2132 fixed to the central magnetic circuit 32, and a fourth deformation part 2133 connecting the outer fixing part 2131 and the inner fixing part 2132. In order to avoid the diaphragm 21 interfering with the central magnetic circuit 32 of the magnetic circuit system 3 when vibrating, the fourth deformation part 2133 bulges in a direction away from the magnetic circuit system 3.

[0038] Furthermore, such as Figure 2-3 As shown, the central magnetic circuit 32 includes a first central magnet 321, a central pole core 322, a second central magnet 323, and a third central magnet 324 stacked sequentially from the lower clamping plate 31. The second central magnet 323 and the third central magnet 324 can be separate magnets or integrated magnets. In this embodiment, the second central magnet 323 and the third central magnet 324 are integrated magnets. The side magnetic circuit 34 includes a side magnet 341 fixed to the lower clamping plate 31 and a side pole core 342 attached to the side magnet 341. The side pole core 342 is fixed to the frame 1.

[0039] Furthermore, the inner fixing part 2132 of the inner folding ring has a cover-like structure and covers the top of the third central magnet 324. It is fixed to the frame 1 by the outer fixing part 2131 of the inner folding ring and the inner fixing part 2132 of the inner folding ring is fixed to the third central magnet 324, thereby realizing the overall stable fixed connection of the diaphragm 21. At the same time, the vibration performance and compliance of the diaphragm 21 are improved by setting the folding ring 212 and the inner folding ring 213.

[0040] (Second Embodiment) Figure 5 The speaker in the second embodiment of the present invention Figure 3 A magnified view of a portion at position C. Compared to the first embodiment, the second embodiment is identical to the first embodiment except for the shape of the damping element 4 and the connection relationship between the damping element 4 and other components. Figure 5As can be seen, the damping element 4 is fixedly fitted to the first deformation portion 2123 of the folded ring 212 and the second deformation portion 233 of the flexible support 23, and is fixedly connected to the extension portion 2112 of the dome 211 and the frame 1. By connecting the damping element 4 to the second deformation portion 233 of the flexible support 23, the damping element 4 can regulate the flexible deformation of the second deformation portion 233, reducing distortion caused by the rebound of the flexible support 23, and significantly improving mid-frequency vibration distortion. In addition, by connecting it to both the folded ring 212 and the flexible support 23, the damping element 4 can play a comprehensive role, further suppressing sound distortion, and also improving the stability and lifespan of the flexible support 23.

[0041] (Third embodiment) Figure 6 The speaker in the third embodiment of the present invention Figure 3 A partially enlarged view of position C. Compared to the first embodiment, the third embodiment is identical to the first embodiment except for the shape of the damping element 4 and the connection relationship between the damping element 4 and other components. Please refer to... Figure 6 In the third embodiment, the damping member 4 is fixedly connected to the first deformation portion 2123 of the folding ring 212, the second deformation portion 233 of the flexible support member 23, and the third deformation portion 241 of the auxiliary diaphragm 24, and is also fixedly connected to the extension portion 2112 of the frame 1 and the dome 211. Figure 6 It is known that at least a portion of the second deformable part 233 of the flexible support 23 is embedded in the damping member 4. This connection configuration allows for global damping optimization of the vibration system 2, enabling multi-level damping to work together to simultaneously suppress the vibration of the diaphragm 21, the auxiliary diaphragm 24, and the flexible support 23, thereby comprehensively suppressing low, mid, and high frequency distortions, improving overall acoustic performance, and enhancing the consistency and reliability of the vibration system 2.

[0042] (Fourth embodiment) Figure 7 The speaker in the fourth embodiment of the present invention Figure 3 A partially enlarged view of position C. Compared to the first embodiment, the fourth embodiment is identical to the first embodiment except for the shape of the damping element 4 and the connection relationship between the damping element 4 and other components. Please refer to... Figure 7In the fourth embodiment, the damping member 4 is fixedly attached to the second deformation portion 233 of the flexible support member 23, and at least part of the second deformation portion 233 is embedded in the damping member 4. When the diaphragm 21 vibrates to produce sound, the second deformation portion 233 deforms and causes the damping member 4 to deform. The damping member 4 is used to increase the vibration damping of the diaphragm 21. When the diaphragm 21 vibrates to produce sound, the deformation of the second deformation portion 233 causes the damping member 4 to deform. The damping effect is achieved by relying on the internal resistance of the damping member 4 itself, thereby increasing the vibration damping of the speaker diaphragm 21, further improving the distortion of the speaker, especially significantly improving the vibration distortion in the mid-frequency range, and improving the reliability of the vibration system 2. Furthermore, by embedding at least a portion of the second deformable part 233 into the damping member 4, the contact area between the damping member 4 and the second deformable part 233 is increased. The damping member 4 can more fully absorb the mechanical energy of the flexible support member 23 during vibration, reducing the vibration residue caused by the elastic recovery of the second deformable part 233. In addition, the wrapping of the second deformable part 233 by the damping member 4 can disperse local stress and delay the fatigue fracture of the second deformable part 233 caused by repeated deformation.

[0043] Preferred, such as Figure 7 As shown, the damping element 4 is fixedly attached to the second deformation portion 233 of the flexible support 23, and is also fixedly connected to the extension portion 2112 of the dome 211 and the frame 1. When the voice coil 22 drives the diaphragm 21 to vibrate and produce sound, the frame 1 is relatively stationary. The damping element 4 is fixed to the frame 1, which firstly allows the internal resistance of the damping element 4 during deformation to achieve the damping effect, secondly makes the fixation of the damping element 4 more secure, reduces the burden of the weight of the damping element 4 on the flexible support 23, and finally reduces the transmission of vibration energy to the frame 1, suppressing the resonance of the frame 1. In addition, the fixed connection between the damping element 4 and the extension portion 2112 of the dome 211 limits high-frequency vibration and improves the high-frequency response.

[0044] (Fifth Embodiment) Figure 8 The loudspeaker in the fifth embodiment of the present invention Figure 3 A partially enlarged view of position C. Compared to the first embodiment, the fifth embodiment is identical to the first embodiment except for the shape of the damping element 4 and the connection relationship between the damping element 4 and other components. Please refer to... Figure 8 In the fifth embodiment, the damping member 4 is fixedly connected to the second deformation portion 233 of the flexible support member 23 and the third deformation portion 241 of the auxiliary diaphragm 24. Figure 8Furthermore, at least a portion of the second deformable portion 233 of the flexible support 23 is embedded in the damping member 4, and both ends of the damping member 4 are respectively connected to the frame 1 and the extension 2112 of the dome 211. With this configuration, the damping member 4 connects both the auxiliary diaphragm 24 and the flexible support 23, absorbing the vibration of the auxiliary diaphragm 24, improving the smoothness of the response, reducing the phase difference between the auxiliary diaphragm 24 and the diaphragm 21, and improving the stability of the auxiliary diaphragm 24 and the flexible support 23. In addition, fixing it to the frame 1 and the extension 2112 effectively suppresses the resonance of the frame 1, reduces the weight of the damping member 4 on the flexible support 23 and the auxiliary diaphragm 24, and improves the high-frequency response of the dome 211.

[0045] (Sixth embodiment) Figure 9 The sixth embodiment of the present invention Figure 3 A partially enlarged view of position C. Compared to the first embodiment, the sixth embodiment is identical to the first embodiment except for the shape of the damping element 4 and the connection relationship between the damping element 4 and other components. Please refer to... Figure 9 In the sixth embodiment, the damping element 4 is fixedly attached to the flexible support 23 and fixedly connected to the third deformation portion 241 of the auxiliary diaphragm 24. With this configuration, the damping element 4 connects both the auxiliary diaphragm 24 and the flexible support 23, absorbing the vibration of the auxiliary diaphragm 24, improving the smoothness of the response, reducing the phase difference between the auxiliary diaphragm 24 and the diaphragm 21, and further reducing the resonance effect between the auxiliary diaphragm 24 and the flexible support 23, thus improving the stability of the auxiliary diaphragm 24 and the flexible support 23.

[0046] (Seventh Embodiment) Figure 10 The loudspeaker in the seventh embodiment of the present invention Figure 3 A partially enlarged view of position C. Compared to the first embodiment, the seventh embodiment is identical to the first embodiment except for the shape of the damping element 4 and the connection relationship between the damping element 4 and other components. Please refer to... Figure 10 In the seventh embodiment, the damping member 4 is fixedly attached to the third deformation portion 241 of the auxiliary diaphragm 24. When the diaphragm 21 vibrates to produce sound, the third deformation portion 241 deforms and causes the damping member 4 to deform as well. The damping member 4 is used to increase the vibration damping of the diaphragm 21. With this configuration, when the diaphragm 21 vibrates to produce sound, the deformation of the third deformation portion 241 will cause the damping member 4 to deform. The damping effect is achieved by relying on the internal resistance of the damping member 4 itself, thereby increasing the vibration damping of the diaphragm 21. At the same time, by adjusting the vibration amplitude of the auxiliary diaphragm 24, the distortion caused by high-frequency vibration is reduced, the clarity of the high-frequency response is improved, the distortion of the speaker is further improved, and the reliability of the vibration system 2 is enhanced.

[0047] Compared with related technologies, the loudspeaker provided by the present invention uses a damping component fixedly attached to the deformable part of the vibration system. Specifically, the damping component is fixedly attached to the first deformable part of the surround, the second deformable part of the flexible support, or the third deformable part of the auxiliary diaphragm. When the diaphragm vibrates and produces sound, the deformation of the deformable part will cause the damping component to deform. The damping effect is achieved by relying on the internal resistance of the damping component itself, thereby increasing the vibration damping of the loudspeaker diaphragm, further improving the distortion of the loudspeaker, and improving the reliability of the vibration system.

[0048] The above are merely embodiments of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
