Description

Technical Field

[0001] The present invention belongs to the technical field of speakers, and specifically relates to a vibration system and a speaker.

Background Art

[0002] As an important component of audio equipment, the structure, shape, etc. of a speaker unit directly affect the performance, design, manufacturing, and installation of an audio system. Currently, the vibration system of a traditional speaker unit includes components such as a diaphragm, a folding ring, a centering disk, and a voice coil, but there are the following problems. The traditional speaker diaphragm is generally a complete sheet material with a conical structure. The voice coil is directly attached to the diaphragm to push the diaphragm in to generate sound. Such a structure generates splitting vibration due to the limitations of the material itself, and the energy distribution from the position of the voice coil to the edge folding ring gradually decreases, resulting in energy imbalance, further reducing the stability of the speaker and increasing the distortion rate. The damper of a traditional speaker includes a centering disk and a folding ring. The centering disk of a conventional speaker is prone to aging, that is, the fatigue resistance gradually decreases with the usage time. Also, since the centering disk of a conventional speaker is attached to the voice coil skeleton, the centering disk occupies the voice coil position, further increasing the thickness of the overall structure of the speaker. In addition, conventional speakers lack phase correction means, and thus the phase distortion and acoustic interference of the speakers are serious.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The objective of the present invention is to at least solve the problems of high distortion rate, too thick structural dimensions, and poor stability of conventional speakers. This objective is achieved by the following technical solutions.

Means for Solving the Problems

[0004] A first aspect of the present invention includes a support frame, at least one first damper provided in close contact with one side of the support frame, a driving member having a number corresponding to that of the first damper and having one end sequentially passing through the support frame and the first damper, a first frame portion, a group of skeleton portions respectively located within the first frame portion, and a fixing portion having a number corresponding to that of the first damper. One side is connected to the first damper located on the support frame, the fixing portion is connected to the first frame portion by the group of skeleton portions, the fixing portion is connected to the one end of the driving member, and includes a diaphragm frame, a diaphragm group, and an annular diaphragm having a number corresponding to that of the first damper. The diaphragm group is provided surrounding the circumferential direction of the annular diaphragm and is provided in close contact with the annular diaphragm together on the side away from each of the first dampers of the group of skeleton portions and the fixing portion, a phase ball assembly having a number corresponding to that of the first damper, provided in close contact with the side of the annular diaphragm close to the diaphragm frame, and having a part extending to the other side of the annular diaphragm, and a second damper sleeved on the outside of each of the diaphragm frame, the diaphragm assembly, the phase ball assembly, and the first damper, connected to the diaphragm frame toward one side of the diaphragm frame, and connected to the support frame toward one side of the support frame, thereby providing a vibration system.

[0005] By using the vibration system and speaker in the present technical solution, an assembly structure of a support frame, a first damper, a driving member, a diaphragm frame, a diaphragm assembly, a phase ball assembly, and a second damper is adopted. The driving member can receive an alternating current to generate an electromagnetic field, further vibrate the driving member, and drive the diaphragm assembly on the vibration frame to vibrate, ultimately achieving the energy exchange effect of the speaker. The support frame fixes the driving member, the first damper, the vibration frame, the diaphragm assembly, and the second damper respectively, improving the stability of the speaker. The first damper is directly connected to the support frame, no longer occupying the position of the driving member, and no longer needing to reserve a thickness space in advance. The overall speaker structure tends to be thin, improving convenience. The diaphragm frame is used to fix the diaphragm assembly and the phase ball assembly, enhancing the stability of both, enabling the speaker to achieve a low-distortion effect and improving the sound quality of the speaker. Also, when the vibration frequency of the phase ball assembly is coupled to a preset frequency, its vibration direction is offset from the vibration direction of the diaphragm, generating a phase difference, and further correcting or canceling the phase distortion of a specific frequency, which can improve the sound quality of the speaker. The diaphragm assembly adopts a combined structure of a diaphragm group and an annular diaphragm, reducing the split vibration of the diaphragm assembly and improving the rigidity modulus.

[0022] FIG. 1 schematically shows an overall structural schematic diagram of a vibration system according to an embodiment of the present invention. FIG. 2 is an overall structural schematic diagram of another perspective of the vibration system in FIG. 1. FIG. 3 is an exploded structural schematic diagram of the vibration system in FIG. 1. As shown in FIGS. 1, 2, and 3, the present invention provides a vibration system 100. The vibration system 100 in the present invention includes a support frame 10, at least one first damper 20, a driving member 30 whose number matches that of the first damper 20, a diaphragm frame 41, a diaphragm assembly 43, a phase ball assembly 42 whose number matches that of the first damper 20, and a second damper 51. The first damper 20 is provided in close contact with one side of the support frame 10. One end of the driving member 30, that is, one end of the voice coil 35, is sequentially connected to the diaphragm frame 41 through the support frame 10 and the first damper 20.

[0023] The diaphragm frame 41 includes a first frame portion 411, a skeleton portion group 413 located within the first frame portion 411 respectively, and fixing portions 412 whose number matches that of the first dampers 20. The fixing portions 412 are connected to the first frame portion 411 by the skeleton portion group 413. The link portion 415 of the diaphragm frame 41 is connected to the first damper 20 located on the support frame 10. The fixing portion 412 is connected to one end of the driving member 30, that is, one end of the voice coil 35. The diaphragm assembly 43 includes a diaphragm group 432 and an annular diaphragm 431 whose number matches that of the first dampers 20. The diaphragm group 432 is provided surrounding the annular diaphragm 431 in the circumferential direction and is provided in close contact with the annular diaphragm 431 on the side away from each of the first dampers 20 of the skeleton portion group 413 and the fixing portion 412. The phase ball assembly 42 is provided in close contact with the side of the annular diaphragm 431 close to the diaphragm frame 41, and a portion of the phase ball assembly 42 extends to the other side of the annular diaphragm 431. The second damper is sleeved on the outside of each of the diaphragm frame 41, the diaphragm assembly 43, the phase ball assembly 42, and the first damper 20. The second damper is connected to the diaphragm frame 41 towards the fourth connection portion 513 on one side of the diaphragm frame 41, and the second damper is connected to the support frame 10 towards the third connection portion 511 on one side of the support frame 10.

[0024] By using the vibration system 100 in this technical solution, an assembly structure of a support frame 10, a first damper 20, a driving member 30, a diaphragm frame 41, a diaphragm assembly 43, a phase ball assembly 42, and a second damper 51 is adopted. The driving member 30 can receive an alternating current to generate an electromagnetic field, and further vibrate the voice coil 35 in the driving member 30, driving the first damper 20, the diaphragm unit 40 "the diaphragm frame 41, the phase ball assembly 42, and the diaphragm assembly 43", and the second damper to vibrate, ultimately achieving the energy exchange effect of the speaker. The support frame 10 fixes the driving member 30, the first damper 20, the diaphragm unit 40, and the second damper respectively, improving the overall stability of the vibration system 100. The first damper 20 is directly connected to the support frame 10, no longer occupying the position of the driving member 30, and no longer needing to reserve a thickness space in advance. The overall structure of the vibration system 100 tends to be thinner, improving convenience. The diaphragm frame 41 is used to fix the diaphragm assembly 43 and the phase ball assembly 42, enhancing the stability of both, further improving the rigidity modulus of elasticity of the diaphragm assembly 43. At the same time, by installing the phase ball assembly 42, the whole vibration system 100 achieves the effect of low distortion, improving the sound quality of the vibration system 100. Also, when the vibration frequency of the phase ball assembly 42 is coupled to a preset frequency, its vibration direction is deviated from the vibration direction of the diaphragm, generating a phase difference, and further being able to correct or offset the phase distortion of a specific frequency, improving the sound quality of the vibration system 100. The diaphragm assembly 43 adopts an assembly structure of a diaphragm group 432 and an annular diaphragm 431, which can reduce the split vibration of the diaphragm assembly 43 and improve the rigidity modulus of elasticity.

[0025] Specifically, in the present invention, the diaphragm frame 41, the diaphragm assembly 43, and the phase ball assembly 42 can be collectively referred to as the diaphragm unit 40.

[0026] In some embodiments of the present invention, as shown in FIGS. 3 and 12, the support frame 10 includes a second frame portion 11, a plurality of support portions 13, and a plurality of mounting portions 12. The number of the mounting portions 12 coincides with the number of the first dampers 20. The mounting portions 12 are installed concentrically with the driving member 30. The mounting portions 12 are located within the second frame portion 11 and the outer periphery thereof is connected to the second frame portion 11. The plurality of support portions 13 are provided around the outer periphery of the second frame portion 11 close to the first damper 20. In this embodiment, the mounting portion 12 fixes and connects the first damper 20 toward one side of the first damper 20, and a connection method such as adhesion may be used. Each of the plurality of support portions 13 can stopper the first damper 20, the diaphragm unit 40, and the second damper inside thereof, and further protect the first damper 20, the diaphragm unit 40, and the second damper. The plurality of support portions 13 may also be connected to other members of the speaker to realize the fixation and mounting to the vibration system 100.

[0027] In some embodiments of the present invention, as shown in FIGS. 3 and 12, the mounting portion 12 includes a first connection portion 121 having a plurality of annular portions 122 and a first inner hole 1211. The plurality of annular portions 122 are provided around the circumferential direction of the first connection portion 121 and are connected to the second frame portion 11. The first inner hole 1211 is fitted to the driving member 30 and installed concentrically. In this embodiment, the first connection portion 121 connects the first damper 20 to realize the connection between the first damper 20 and the support frame 10. By providing the plurality of annular portions 122 around the circumferential direction of the first connection portion 121 and connecting the first connection portion 121 and the second frame portion 11 respectively, it can correspond to the piston portion 22 of the first damper 20. The first damper 20 provides a piston motion when the vibration system 100 emits sound, provides a specific compliance and attenuation to the diaphragm unit 40 that abuts against it, further improves the stability of the overall structure of the vibration system 100, can also improve the sound quality, and can reduce the distortion rate. The first inner hole 1211 is installed concentrically with the driving member 30, further accurately positions the voice coil 35 of the driving member 30, and improves the mounting accuracy and the linear piston motion of the voice coil 35.

[0028] In some embodiments of the present invention, as shown in FIGS. 9 and 10, the first damper 20 includes a second connecting portion 21 having a second inner hole 211 and a piston portion 22 whose number coincides with the annular portion 122. A plurality of piston portions 22 are provided around the circumferential direction of the second connecting portion 21. The piston portion 22 is located within the annular portion 122 and installed concentrically with the annular portion 122. The second connecting portion 21 is provided in close contact with the side of the diaphragm frame 41 of the first connecting portion 121 close to the driving member 30. The second inner hole 211 is installed concentrically with the voice coil 35 of the driving member 30. In this embodiment, the second connecting portion 21 is attached and connected to the first connecting portion 121. The piston portions 22 are provided around the circumferential direction of the second connecting portion 21 and are respectively located within the annular portion 122. When the vibration system 100 vibrates and emits sound, the piston portion 22 located within the annular portion 122 of the first damper 20 is moved, providing specific compliance and attenuation to the diaphragm unit 40 that abuts against it.

[0029] Specifically, a traditional damper includes a centering disk and a folding ring, and these two members are completely replaced in a new form in this embodiment. The first damper 20 in this embodiment is no longer attached to the voice coil 35 in the driving member 30 like a centering disk, so it no longer occupies the position between the driving member 30 and the diaphragm, and there is no need to reserve a thickness space in advance. There is a first advantage that the overall structure of the vibration system 100 tends to be thinner. At the same time, the first damper 20 adopts elastic rubber vulcanization molding, but does not use the conventional various cotton spinning fiber cloths of the centering disk after rubber dipping and then hot press molding. Therefore, the first damper 20 has excellent elasticity, is easy to vibrate, is easy to generate specific compliance and attenuation, can improve the sound quality of the vibration system 100, and can reduce the distortion rate, but is not as easy to age and fatigue short-lived as a centering disk.

[0030] Specifically, in this embodiment, the piston portion 22 is composed of a corrugated sheet body provided in an annular shape, and a round hole for accommodating the link portion 415 of the diaphragm frame 41 is provided at the center. In addition, the piston portion 22 is further provided with petal-shaped openings, further reducing wind resistance and improving compliance.

[0031] In some embodiments of the present invention, as shown in FIGS. 6 and 7, a third inner hole 4121 is provided in the fixing part 412, a group of skeleton parts 413 is connected between the first frame part 411 and the fixing part 412, the diaphragm group 432 is provided in close contact with the group of skeleton parts 413 and can seal the group of skeleton parts 413, the annular diaphragm 431 is provided in close contact with the fixing part 412 and can seal the third inner hole 4121, and the third inner hole 4121 is fitted to the driving member 30 and installed concentrically. In this embodiment, the fixing part 412 connects and fixes the voice coil 35 in the driving member 30, and the group of skeleton parts 413 connects the first frame part 411 and the fixing part 412 respectively. In this embodiment, the diaphragm frame 41 of the overall structure is difficult to deform, can withstand a large load, and can increase the load power.

[0032] Specifically, in this embodiment, as shown in FIGS. 6 and 7, the diaphragm frame 41 is a truss of a Truss structure, the group of skeleton parts 413 is a plurality of ribs "rib-shaped" with horizontal and vertical intersections or triangular, circular and other irregular shapes, and a watermark carving structure 414 is provided thereon, thereby constituting an overall rigid member. One side of the group of skeleton parts 413 is bonded to the diaphragm, and the fixing part 412 on the other side can withstand a large load by attaching the voice coil 35 in the driving member 30, and further improve the overall stability performance of the vibration system 100.

[0033] Specifically, in this embodiment, as shown in FIGS. 6, 7, and 8, the diaphragm frame 41 can be designed in two modes: a planar frame configuration and a three-dimensional frame configuration. In both cases, the annular fixing portion 412 of the voice coil 35 in the driving member 30 that abuts against it is mechanically centered, and the mechanical force or acoustic energy from the driving member 30 is uniformly diffused and propagated throughout the Truss network. As shown in FIG. 6, all the skeleton part groups 4131 of the diaphragm frame 41 having a planar structure are in one plane. As shown in FIG. 8, the skeleton part groups 413 of the diaphragm frame 41 having a three-dimensional structure are in different planes. Among them, the end face of the annular fixing portion 412 that abuts against the voice coil 35 in the driving member 30 is in a lower plane, but the second frame portion 11 that abuts against the second damper is in a higher plane "that is, the height of the second frame portion 11 toward the second damper is greater than the height of the fixing portion 412 toward the second damper", and the skeleton part group 413 connecting the second frame portion 11 and the fixing portion 412 gradually and smoothly transitions from the lower plane to the higher plane.

[0034] In some embodiments of the present invention, as shown in FIGS. 6 and 7, the diaphragm frame 41 further includes a plurality of link portions 415, and the plurality of link portions 415 are provided around the side facing the first damper 20 of the skeleton part group 413 between the outer periphery of the third inner hole 4121 and the first frame portion 411. The link portion 415 can sequentially pass through the first damper 20 and the support frame 10 to perform attenuation positioning and balance fixing by the first damper 20. In this embodiment, as shown in FIG. 11, the plurality of link portions 415 are fitted corresponding to the piston portion 22 of the first damper 20, stopped by the first damper 20, and while the piston portion 22 of the first damper 20 performs axial vibration along its respective center line direction, the entire vibration system is also stopped and guaranteed to perform axial vibration. That is, when the vibration system 100 vibrates and emits sound, it provides piston motion to generate specific compliance and attenuation, further improves the sound quality effect, and reduces its distortion rate.

[0035] Furthermore, in this embodiment, as shown in FIG. 13, the diaphragm assembly 43 has a splice structure and includes an annular diaphragm 431 and a diaphragm group 432. The diaphragm group 432 is provided surrounding the annular diaphragm 431 in the circumferential direction. Among them, the diaphragm group 432 further includes a plurality of diaphragms of different shapes. That is, the diaphragm assembly 43 cuts a sheet body plate material of the same or different materials into sheet bodies of a plurality of different cross-sectional shapes according to the requirements of different regions, stopper shapes, mechanical conduction coefficients, etc. of the skeleton part group 413 of the diaphragm frame 41, and joins and bonds the cut sheet bodies to the top of the diaphragm frame 41 like a jigsaw puzzle, and finally forms a sealed plane, together with the diaphragm frame 41, the first damper 20, and the second damper, to form a vibration system 100, thereby reducing the split vibration of the diaphragm assembly 43 and improving the rigid elastic modulus.

[0036] Specifically, in this embodiment, the diaphragm assembly 43 can be composed of different materials, thicknesses, or laminations of multi-layer composite materials such as sandwiches in addition to a unified material. In order to achieve a uniform energy distribution and reduce distortion, the mechanical conduction coefficient and thermal equilibrium are adjusted by different materials, thicknesses, etc.

[0037] In some embodiments of the present invention, the annular diaphragm 431 is installed concentrically with the voice coil 35 in the driving member 30, and the stability and reliability in the vibration process of the vibration system 100 can be guaranteed.

[0038] In some embodiments of the present invention, as shown in FIGS. 3 and 4, the phase ball assembly 42 includes an annular elastic rubber ring 422 that is installed concentrically with the drive member 30 and has a mass ball 421 and a mounting hole. The mass ball 421 is located within the mounting hole and is connected to the annular elastic rubber ring 422. In this embodiment, the phase ball assembly 42 is a spherical or hemispherical swing device specially provided to remove sound interference based on a principle similar to that of a tuning mass damper (TMD) in a skyscraper. The phase ball assembly 42 is composed of a combination of the mass ball 421 and the annular elastic rubber ring 422. The mass ball 421 provides a resonant mass, and the annular elastic rubber ring 422 acts like a spring to provide elasticity and damping to the mass ball 421 and is attached onto a specific diaphragm assembly 43. Such a special device of the phase ball assembly 42 is mainly used for problems such as eliminating mid- and low-frequency phase distortion in subwoofers or large-diameter mid- and low-frequency speakers. During its operation, when the vibration frequency is coupled to a preset frequency, the vibration direction thereof and the vibration direction of the vibrating diaphragm are displaced to generate a phase difference. When the phase difference reaches about 90° - 180°, the effect is also optimal, correcting, coupling, or canceling the phase of a specific frequency, and further reducing the sound interference of the diaphragm assembly 43 caused by phase distortion.

[0039] In some embodiments of the present invention, as shown in FIGS. 3 and 14, the second damper is the first annular structure 51. The first annular structure 51 includes a third connection portion 511, a transition portion 512, and a fourth connection portion 513. The transition portion 512 connects the third connection portion 511 and the fourth connection portion 513 respectively. The third connection portion 511 is connected to the support frame 10, and the fourth connection portion 513 is connected to the diaphragm frame 41. In this embodiment, as shown in FIGS. 4 and 5, the first annular structure 51 is formed at a viewing angle perpendicular to the diaphragm assembly 43 or the diaphragm frame 41. Thus, it looks different from the traditional damper by 90°. The main use of the second damper is to ensure the sealing connection between the support frame 10 and the diaphragm frame 41, and on the premise of ensuring its compliance and attenuation, reduce the cross-sectional area occupied by the second damper, and compensate the reduced cross-sectional area on the diaphragm assembly 43 to increase the effective cross-sectional area of the diaphragm assembly 43.

[0040] In some embodiments of the present invention, as shown in FIGS. 15, 16, and 17, when the support frame 10 of the vibration system is applied in other embodiments, the second damper is the second annular structure 52. The second annular structure 52 includes a fifth connection portion 521, a corrugated portion 522, and a sixth connection portion 523. The corrugated portion 522 connects the fifth connection portion 521 and the sixth connection portion 523 respectively. The fifth connection portion 521 is connected to the diaphragm frame 41, and the sixth connection portion 523 is connected to the support frame 10. In this embodiment, the second annular structure 52 is formed at a viewing angle perpendicular to the diaphragm assembly 43 or the diaphragm frame 41. The second damper of the second annular structure 52 is a simplified alternative to the second damper of the first annular structure 51. That is, when the support frame 10 is applied in other embodiments, that is, when the second annular structure 52 of this solution is adopted, the second annular structure 52 in this embodiment does not have the advantages of the first annular structure 51 of reducing its own cross-sectional area or reinforcing the cross-sectional area of the diaphragm assembly 43, but can seal the connection between the support frame 10 and the diaphragm frame 41. The corrugated portion in this embodiment includes a crest portion and a trough portion, and a spherical structure 5221 is further provided on the crest portion.

[0041] In some embodiments of the present invention, as shown in FIG. 3, the drive member 30 includes a magnetic conductor 31, a magnet 32, a washer 33, and a voice coil 35. An attachment cavity 311 is provided in the magnetic conductor 31. The magnet 32 and the washer 33 are sequentially provided in the attachment cavity 311 along the axial direction of the magnetic conductor 31. One end of the voice coil 35 is inserted into the gap between the washer 33 and the magnetic conductor 31, and the other end of the voice coil 35 is connected to the diaphragm unit 40, and can reciprocate linearly along the axial direction of the magnetic conductor 31. The magnet 32 and the washer 33 are provided in a bonded manner and are provided together in the attachment cavity 311, and a magnetic slit is formed at a distance from the inner wall of the magnetic conductor 31, so as to ensure that the voice coil 35 is inserted between the magnetic slits formed by the magnetic conductor 31, the magnet 32, and the washer 33, and reciprocates along its own axial direction. Specifically, one end of the voice coil 35 is inserted between the magnetic slits formed by the magnetic conductor 31, the magnet 32, and the washer 33, and the other end of the voice coil 35 passes through the second frame portion 11 and the second inner hole 211 respectively, and finally fits into the third inner hole 4121, further realizing the drive of the diaphragm unit 40.

[0042] Specifically, as shown in FIG. 3, the drive member 30 further includes an electrical connector 36. One end of the electrical connector 36 is connected to the voice coil 35, and the other end of the electrical connector 36 is connected to an external amplification power supply. The electrical connector 36 can provide an alternating current to the voice coil 35 to cause vibration, and finally achieve the "electrical-force-sound" energy exchange and the loudspeaker effect of the vibration system 100.

[0043] Specifically, in other embodiments of the present invention, the diaphragm frame 41 and the diaphragm assembly 43 in the vibration system 100 can also be integrally formed by a mold with the same material.

[0044] Furthermore, in one embodiment of the present invention, the number of the first damper 20, the drive member 30, the mounting portion 12, the second connection portion 21, the fixing portion 412, the phase ball assembly 42, and the annular diaphragm 431 is two, and the number of the piston portion 22 and the annular portion 122 is four each. In other embodiments of the present invention, these component arrays can be used without limitation.

[0045] The present invention further provides a speaker having the above vibration system 100.

[0046] By using the speaker in this technical solution, an assembly structure of a support frame 10, a first damper 20, a driving member 30, a diaphragm frame 41, a diaphragm assembly 43, a phase ball assembly 42, and a second damper is adopted. The driving member 30 can receive an alternating current to generate an electromagnetic field, and further vibrate the voice coil 35 in the driving member 30, driving the first damper 20, the diaphragm unit 40 "the diaphragm frame 41, the phase ball assembly 42, and the diaphragm assembly 43", and the second damper to vibrate, ultimately achieving the energy exchange effect of the speaker. The support frame 10 fixes the driving member 30, the first damper 20, the diaphragm unit 40, and the second damper respectively, improving the overall stability of the speaker. The first damper 20 is directly connected to the support frame 10, no longer occupying the position of the driving member 30, and no longer needing to reserve a thickness space in advance. The overall structure of the speaker tends to be thinner, improving convenience. The diaphragm frame 41 is used to fix the diaphragm assembly 43 and the phase ball assembly 42, strengthening the stability of both, further improving the rigidity modulus of elasticity of the diaphragm assembly 43. At the same time, by installing the phase ball assembly 42, the whole speaker achieves the effect of low distortion, improving the sound quality of the speaker. Also, when the vibration frequency of the phase ball assembly 42 is coupled to a preset frequency, its vibration direction is displaced from the vibration direction of the diaphragm, generating a phase difference, and further being able to correct or offset the phase distortion of a specific frequency, improving the sound quality of the vibration system 100. The diaphragm assembly 43 adopts an assembly structure of a diaphragm group 432 and an annular diaphragm 431, which can reduce the split vibration of the diaphragm assembly 43 and improve the rigidity modulus of elasticity.

[0047] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Changes or substitutions that can be easily conceived by those skilled in the art within the disclosed technical scope of the present invention should be included within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
