[0077] Another purpose of the embodiment of the present application is to provide a sound support with low resonance probability and good sound quality.

[0078] To achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

[0079] A sound frame, comprising:

[0080] A plurality of spaced-apart stacked sound single-layer supports, and a spacing column for connecting two adjacent sound single-layer supports;

[0081] The sound single-layer support is the sound single-layer support described above.

[0082] Another purpose of the embodiments of the present application is to provide a sound equipment with good sound quality and no resonance noise.

[0083] To achieve the above purpose, the embodiments of the present application adopt the following technical solutions:

[0084] A sound equipment, comprising:

[0085] A sound frame located at a to-be-installed position, wherein the sound frame is the sound frame described above;

[0086] A diaphragm arranged in the diaphragm accommodating hole, and a conductor on the diaphragm is located at the circumferential side of the projection of the opposite magnet of the sound frame on the diaphragm.

[0088] The conductor on the diaphragm is located in the magnetic field at the opposite gap, and when the current flows through the conductor, the conductor is forced to vibrate, thereby driving the diaphragm to vibrate to emit sound. In the prior art, the magnet support partially blocks the sound emitted by the diaphragm, and this part of the blockage will cause sound wave reflection and diffraction at the corresponding frequency point, so that the SPL curve at the listening position is unstable. By reducing the size of the blocking surface, the sound wave frequency blocked is in a range that is difficult for the human ear to detect, and / or by setting the width of the diaphragm accommodating hole at different positions around the magnet mounting groove to be different, the hole wall of the diaphragm accommodating hole presents different shapes. Due to the change of the hole wall shape, the sound wave will be diffracted and reflected when it hits the hole wall, so that the superposition and cancellation of the sound wave at the listening position are dispersed at different frequencies, thereby improving the frequency response curve of the sound.

[0089] When the vibration frequency of the diaphragm is the same as the resonance frequency of the sound support, the magnet support resonates, thereby affecting the sound quality of the sound, the inventor sets multiple support plates in a laminated manner, and the adhesive layer can change the resonance frequency of the single-layer support of the sound, thereby effectively preventing the single-layer support from resonating due to the sound, and ensuring the good sound quality of the sound emitted by the diaphragm. The sound frame and the sound equipment apply the above-mentioned single-layer support of the sound, which can ensure that the sound frame is not affected by the sound emitted by the diaphragm, avoid the resonance of the sound frame, and ensure that the sound equipment has good sound quality.

[0110] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application. The "comprise" mentioned in the whole specification and claims is an open term, which should be interpreted as "comprise but not limited to". "Approximately" means that the technical problem can be solved within a certain error range and the technical effect can be basically achieved by those skilled in the art within a certain error range. In addition, in the embodiments of the present application, multiple means two or more. Those skilled in the art can combine and combine the features of different embodiments or examples described in the specification and the features of different embodiments or examples in the embodiments of the present application without contradiction.

[0111] The embodiment of the present application provides a sound body 1A, please refer to FIG. 1A-3A, the height of the sound body 1A is adjustable, can adapt to different sizes of sound equipment, to meet different needs of users, for example, the height of the sound body 1A can be reduced to meet the user in the family. The height of the sound body 1A can also be increased to meet the user in outdoor or larger site. It can be understood that the user's demand for sound equipment in different scenes is determined according to the performance of the sound emitted by the sound equipment, the diaphragm 2A is the main unit of the sound equipment capable of emitting sound, and the size of the diaphragm 2A and the magnetic field strength determine the performance of the sound emitted by the sound equipment, the sound body 1A is a carrier for supporting the diaphragm 2A, therefore, when the size of the sound equipment is different, the height of the sound body 1A and the size of the diaphragm 2A need to be changed simultaneously.

[0112] Specifically, one of the sizes of the diaphragm 2A can be adjusted in a way that different sizes of the diaphragm 2A can be replaced according to different sound equipment required by the user, for example, when the user needs to place the sound in the study, according to the space of the study, the sound single-layer support 10A of fewer layers can be configured, and the smaller diaphragm 2A is replaced, and then the floor type or hanging type is selected according to the user's daily listening position, so as to meet the higher requirement of the user's listening experience. When the user needs to configure in a larger scene, for example, a home theater, the immersion requirement for watching is very high, at this time, the sound can be customized and designed according to the environment of the home theater, more layers of the sound single-layer support 10A and the larger diaphragm 2A matched with the sound single-layer support 10A are configured, and at this time, the sound can also be placed in the sky and the ground to form a line sound source, so that good listening experience can be obtained in any direction of the sound. The diaphragm 2A can emit sound because the sound body 1A is provided with a plurality of pairs of same-pole opposite magnets 31A, the opposite gap is formed between the two opposite magnets 31A, the same-pole opposite magnets 31A make the opposite gap have a stable and high-strength magnetic field, and the diaphragm 2A is arranged in the opposite gap, so that the conductor on the diaphragm 2A is located in the magnetic field. When the current flows in the conductor, the conductor is vibrated under the action of the magnetic field, so as to drive the diaphragm 2A to vibrate and emit sound. Next, the sound body 1A will be described in detail in combination with FIG. 1A-3A.

[0113] Referring to FIGS. 1A-3A, the sound body 1A includes a sound single-layer support 10A and a penetrating assembly 20A. A plurality of sound single-layer supports 10A are sleeved on the penetrating assembly 20A. The penetrating assembly 20A can separate and stack adjacent sound single-layer supports 10A in the height direction, so that there is a gap between the two adjacent sound single-layer supports 10A, avoiding hindering the propagation of sound. The penetrating assembly 20A penetrates all the sound single-layer supports 10A that make up the sound body 1A, which can ensure the structural strength of the sound body 1A. The sound single-layer support 10A is centrally provided with a through diaphragm accommodating hole 11A. Along the width direction of the sound single-layer support 10A, a plurality of magnet accommodating holes are symmetrically arranged on the hole walls on both sides of the diaphragm accommodating hole 11A. A magnet 31A is accommodated in the magnet accommodating hole. The diaphragm 2A is sleeved in the diaphragm accommodating hole 11A. The number of sound single-layer supports 10A, the length of the penetrating assembly 20A, and the size of the diaphragm 2A can be adjusted, so that the height of the sound body 1A can be freely configured to meet the needs of sound equipment in different scenarios. For example, the volume of the sound body 1A can be increased by increasing the number of sound single-layer supports 10A and adjusting the length of the penetrating assembly 20A. Similarly, the volume of the sound body 1A can be reduced by reducing the number of sound single-layer supports 10A and shortening the length of the penetrating assembly 20A.

[0114] Since the diaphragm 2A has a certain length, referring to FIGS. 1A-3A, in order to keep the conductor in the diaphragm 2A in a stable magnetic field, two magnets 31A with the same polarity are oppositely arranged in the corresponding magnet mounting groove, and the diaphragm 2A is sleeved in the diaphragm accommodating hole 11A. Since the sound body 1A is formed by separating and stacking a plurality of sound single-layer supports 10A, and each sound single-layer support 10A has the same opposite magnets 31A, the conductor in the diaphragm 2A is kept in a stable magnetic field.

[0115] Specifically, the magnet 31A has a N pole (north pole) and a S pole (south pole). The same-pole opposite here refers to the two magnets 31A being oppositely arranged and having the same polarity of the opposite poles. The opposite poles are not in contact with each other, but have a certain gap to form an effective magnetic field region. When the two magnets 31A are oppositely arranged, the magnetic fields of the two magnets 31A will affect each other, so that the magnetic fields of the two magnets 31A are concentrated in the opposite gap, and the magnetic field direction is biased to be approximately perpendicular to the internal magnetic field direction of the magnet 31A. This arrangement is conducive to concentrating the magnetic fields of the two magnets 31A in the opposite gap, thereby effectively improving the magnetic field strength in the opposite gap.

[0116] The diaphragm 2A is arranged in the opposite gap, and the conductive body is arranged on the diaphragm 2A. When the current passes through the conductive body, the conductive body is subjected to the magnetic field force. When the current is an audio current of a certain frequency, the conductive body also vibrates at a certain frequency, thereby driving the diaphragm 2A to vibrate.

[0117] Further, in order to obtain a stronger and more stable magnetic field to obtain better sound quality, two same-pole opposite magnets 31A form a magnet group 3A, the magnet group 3A can have multiple pairs, each pair of magnets 31A has an opposite gap, and the opposite poles of adjacent magnet groups 3A are different. The diaphragm 2A is arranged in the opposite gap, and the conductive body on the diaphragm 2A is located between the projections of the adjacent magnet groups 3A on the diaphragm 2A, so that the conductive body is located in the strongest and most stable magnetic field, thereby enhancing the sound efficiency and improving the sound quality.

[0118] In order to enable the sound equipment to be freely customized according to the needs of the user scene, in addition to the height of the sound being customizable, the position of the sound is also within the customization range. Please refer to FIGS. 1A-3A. In some embodiments of the present application, the sound body 1A further comprises a top plate 30A which is detachably sleeved on the through component 20A, and the top plate 30A is located above the top-end sound single-layer support 10A. The top plate 30A can be installed on a hoisting position. The top plate 30A can have a hoisting structure such as a lifting ring, and the hoisting position can have a lifting rope which is detachably connected with the lifting ring to hoist the sound body 1A on the hoisting position. Alternatively, the top plate 30A can be screwed with a hanger, and the other end of the hanger is installed on the hoisting position. Alternatively, the top plate 30A can be screwed on the hoisting position by expansion screws to realize the hoisting of the sound body 1A.

[0119] Of course, in another embodiment of the present application, the sound body 1A further comprises a bottom plate 40A which is detachably sleeved on the through component 20A, and the bottom plate 40A is located below the bottom-end sound single-layer support 10A. The bottom plate 40A can enable the sound equipment to be placed on a to-be-placed position. The bottom plate 40A can be a floor-standing power amplifier box, which is collectively referred to as the bottom plate 40A. Whether the sound body 1A has a bottom plate 40A or a top plate 30A depends on the room properties and the preset listening position in the room. Of course, in some large space scenarios, the sound body 1A can have a height that reaches the sky and the ground. At this time, the sound body 1A can be hoisted by the top plate 30A and supported by the bottom plate 40A, which can keep the stability of the sound structure, so that the entire diaphragm 2A forms a line sound source, the listening range is wider, and each angle of the sound body 1A achieves good listening effect.

[0120] It should be noted that, since the magnet 31A is accommodated in the sound rack, if the sound rack is made of magnetic material, the magnetic field generated by the magnet 31A will change, therefore, the sound single-layer support 10A, the penetrating assembly 20A, the top plate 30A and the bottom plate 40A are all made of non-magnetic material.

[0121] In order to realize the stable connection between the two adjacent sound single-layer supports 10A, the sound single-layer support 10A and the bottom plate 40A, or the sound single-layer support 10A and the top plate 30A, in some embodiments of the present application, the penetrating assembly 20A has a plurality of, and the plurality of penetrating assemblies 20A are uniformly spaced along the axial direction of the sound single-layer support 10A and penetrate the sound single-layer support 10A, the bottom plate 40A and the top plate 30A. For example, please refer to FIGS. 3A-5A, the penetrating holes are located at the four corners of the sound single-layer support 10A for the penetrating assembly 20A to pass through.

[0122] Further, in some embodiments of the present application, please refer to FIG. 5A, the through assembly 20A comprises a through rod 23A, a spacer column 24A and a cover 25A, wherein the through rod 23A is arranged on the acoustic single-layer support 10A, the top plate 30A and / or the bottom plate 40A, the through rod 23A has a first connecting structure, and the length of the through rod 23A is adjustable. The spacer column 24A is sleeved on the through rod 23A and located between the acoustic single-layer support and one of the adjacent acoustic single-layer support 10A, the top plate 30A or the bottom plate 40A, the length of the spacer column 24A is adjustable, so as to adjust the distance between the adjacent two acoustic single-layer supports 10A, the acoustic single-layer support 10A and the top plate 30A or the acoustic single-layer support 10A and the bottom plate 40A, so as to meet the requirements of the magnetic system and the conductive circuit design of the acoustic body 1A. The cover 25A covers the top end and / or the bottom end of the through rod 23A and abuts against the bottom surface of the bottom plate 40A, the top plate 30A, the bottom surface of the acoustic single-layer support 10A at the bottom end or the top surface of the acoustic single-layer support 10A at the top end, the cover 25A has a second connecting structure, and the second connecting structure is detachably connected with the first connecting structure. When the acoustic device is placed on a plane, the acoustic body 1A can only have the bottom plate 40A without the top plate 30A, at this time, the bottom plate 40A has a second structure, the first structure at the bottom end of the through rod 23A is matched with the second structure on the bottom plate 40A to cover the bottom end of the through rod 23A. Thus, the acoustic body 1A can be placed on the plane to be placed through the bottom plate 40A. After the top end of the through rod 23A passes through the acoustic single-layer support 10A at the top end, the cover 25A covers the top end of the through rod 23A and is connected with the top end of the through rod 23A through the cooperation of the first connecting structure and the second connecting structure, and at the same time, when the cover 25A is covered and installed at the top end of the through rod 23A, the cover 25A abuts against and tightly abuts against the acoustic single-layer support 10A at the top end, so that the spacer column 24A tightly abuts against the acoustic single-layer supports 10A or the bottom plate 40A on the upper and lower sides to limit the positions of the acoustic single-layer supports 10A and the bottom plate 40A. When the acoustic device is hung on a hanging position, the acoustic body 1A can only have the top plate 30A without the bottom plate 40A, at this time, the top plate 30A has a second structure, the first structure at the top end of the through rod 23A is matched with the second structure on the top plate 30A to cover the top end of the through rod 23A, or after the top end of the through rod 23A passes through the top plate 30A, the cover 25A covers the top end of the through rod 23A and the bottom end of the cover 25A abuts against the top surface of the top plate 30A.The bottom end of the penetrating rod 23A penetrates the sound single-layer support 10A at the bottom end, and then matches and connects the first structure at the bottom end of the penetrating rod 23A with the second structure on the sealing piece 25A, so that the sealing piece 25A covers the bottom end of the penetrating rod 23A and abuts against the bottom surface of the sound single-layer support 10A at the bottom end, so that the spacer column 24A abuts against the sound single-layer supports 10A on the upper and lower sides or the top plate 30A, so as to limit the positions of the sound single-layer supports 10A and the top plate 30A. When the sound body 1A is a structure penetrating the sky and the earth, that is, not only needs to be hoisted but also needs to be placed on a plane, the second connecting structure is arranged on the top plate 30A and the bottom plate 40A, the top plate 30A matches and connects with the first connecting structure at the top end of the penetrating rod 23A, and the bottom plate 40A matches and connects with the first structure at the bottom end of the penetrating rod 23A, so that the top plate 30A covers the top end of the penetrating rod 23A, and the bottom plate 40A covers the bottom end of the penetrating rod 23A. The top plate 30A abuts against the spacer column 24A at the top end, and the bottom plate 40A abuts against the spacer column 24A at the bottom end, so as to limit the positions of all the spacer columns 24A and the sound single-layer supports 10A on the sound body 1A.

[0123] Further, in some embodiments of the present application, the outer periphery of the penetrating rod 23A is provided with the first connecting structure, and the inner periphery of the spacer column 24A is provided with the second connecting structure. The second connecting structure on the spacer column 24A matches and connects with the first connecting structure on the penetrating rod 23A, so that the spacer column 24A is sleeved on the penetrating rod 23A, so as to limit the position of the spacer column 24A on the penetrating rod 23A. After the bottom plate 40A, the top plate 30A or part of the sound single-layer supports 10A are disassembled from the penetrating rod 23A, the positions of the remaining spacer columns 24A and the sound single-layer supports 10A will not be shifted. When the height of the sound body 1A is too high, the penetrating rod 23A can be spliced by multiple rods, and the joint position can be selected in the spacer column 24A to ensure the structural strength of the sound body 1A.

[0124] In some other embodiments of the present application, the top end and the bottom end of the penetrating rod 23A have the first connecting structure. When the sound single-layer supports 10A and the spacer columns 24A are sleeved on the penetrating rod 23A, the top plate 30A or the bottom plate 40A abuts against the corresponding spacer column 24A, and the sealing piece 25A abuts against the corresponding sound single-layer support 10A after the second connecting structure on the top plate 30A or the second connecting structure on the bottom plate 40A and the second connecting structure on the sealing piece 25A match and connect with the first connecting structure on the penetrating rod 23A, so as to achieve the effect of pulling the penetrating rod 23A at both ends, thereby limiting the positions of the sound single-layer supports 10A and the spacer columns 24A. The assembly of the sound body 1A is more convenient, and the installation time is saved. The first connecting structure can be external threads, and the first connecting structure can be internal threads. Correspondingly, the sealing piece 25A can be a nut. The connection strength of the threaded connection is reliable, and the assembly is simple.

[0125] The embodiment provides an acoustic device, which comprises an acoustic body 1A and a diaphragm 2A, wherein the acoustic body 1A is the acoustic body 1A provided in the first embodiment, the acoustic body 1A can be top hoisted, bottom fixed, or a through-the-sky complete structure with simultaneous bottom fixed and top hoisted. The diaphragm 2A is arranged in the acoustic body 1A, and the conductive circuit 22A on the diaphragm 2A is located at the opposite gap, so as to vibrate and sound when the magnetic field acts on the conductive body on the diaphragm 2A when current flows through the conductive body.

[0126] In order to make the acoustic device be customized according to the needs of customers, in some embodiments of the present application, when a user needs to place the acoustic device in a study, according to the space of the study, a single-layer support 10A of fewer layers can be configured, and a smaller diaphragm 2A is replaced, and then according to the daily listening position of the user, a floor type or a hanging type can be selected, so as to meet the higher listening experience of the user. When the user needs to configure in a larger scene, for example, a home theater or a bar, the immersion requirement for viewing is very high, at this time, the acoustic device can be customized and designed, and more layers of the single-layer support 10A of the acoustic device and the larger diaphragm 2A matched therewith can be freely configured according to the environment of the home theater, and at the same time, a through-the-sky complete placement mode can be selected to form a line sound source, so that a good listening experience can be obtained regardless of the direction of the acoustic device.

[0127] Referring to FIGS. 1 to 3, in an embodiment of the present application, a diaphragm 1 is provided, which is suitable for a magnetic system with same-pole opposite arrangement, the magnetic system comprises a plurality of magnet groups 2, each magnet group 2 comprises at least two magnet pairs, for example, a first magnet pair 21 and a second magnet pair 22 in FIG. 1, the first magnet pair 21 comprises two magnet units 4 with N poles arranged in opposition, the second magnet pair 22 comprises two magnet units 4 with S poles arranged in opposition, each magnet pair can also be considered as a pair of magnet units, along the arrow X direction in FIG. 1, the different magnet pairs are arranged in opposition with opposite poles. The magnet units 4 arranged in the same-pole opposite arrangement are provided with opposite gaps, the diaphragm 1 is arranged in the opposite gaps 10 of the plurality of magnet units 4, the arrow Y direction in FIG. 1 can be considered as the width direction of the opposite gap, and the width direction of the diaphragm 1 is perpendicular to the width direction of the opposite gap 10. Along the arrow Z direction in FIG. 1, the plurality of magnet groups 2 are arranged in opposition with opposite poles.

[0128] It is to be noted that each magnet unit 4 includes N-pole and S-pole, and the same-pole opposite magnet units 4 are located on different sides of the diaphragm 1 and oppositely arranged, which means that the magnetic poles of the magnet units 4 oppositely arranged on different sides of the diaphragm 1 are the same, for example, in FIG. 3, the two magnet units 4 of the first magnet pair 21 are both N-pole facing the diaphragm 1. The opposite magnetic poles of the adjacent magnet pairs are opposite, which means that the two magnetic pole units 4 of the first magnet pair 21 are N-pole opposite, and the two magnetic pole units 4 of the second magnet pair 22 are S-pole opposite. The magnetic pole directions of the adjacent magnet groups 2 are opposite, which means that the opposite magnetic poles of the adjacent magnet pairs in the adjacent magnet groups 2 are different, for example, referring to FIG. 4, the first magnet pair 21 in the first magnet group 2 is adjacent to the second magnet pair 22 in the second magnet group 2, that is, each first magnet pair 21 is surrounded by the second magnet pair 22 in the magnetic system.

[0129] Further, referring to FIG. 3, the diaphragm 1 includes a support layer 11 and at least one conductive circuit 12, the at least one conductive circuit 12 is arranged on the support layer 11, the support layer 11 is used to provide support for the conductive circuit 12, and the conductive circuit 12 can also drive the support layer 11 to vibrate when vibrating, thereby improving the effective vibration area of the diaphragm 1 and improving the sound level of the sound.

[0130] Since the magnet units 4 in the magnet group 2 are arranged in the same-pole opposite manner, the magnetic fields at different positions around the magnet group 2 are different, not only the magnetic fields corresponding to different positions on the diaphragm 1 are different, but also the magnetic fields at different positions on the diaphragm 1 change when the diaphragm 1 vibrates. In order to make the diaphragm 1 vibrate more stably and make more effective use of the magnetic field in the opposite gap 10, it is necessary to optimize the arrangement of the conductive circuit 12 on the diaphragm 1, so that each part of the conductive circuit 12 is more reasonably stressed during the vibration of the diaphragm 1, the bad vibration mode of the diaphragm 1 is reduced, the total harmonic distortion is reduced, and the sound quality is improved.

[0131] Referring to FIGS. 1-5, the planes where the magnet units 4 on both sides of the diaphragm 1 and the diaphragm 1 are considered to be parallel to each other, so each magnet unit 4 will have a projection on the plane where the support layer 11 is located. Based on the projection of the magnet unit 4 on the support layer 11, the track of the conductive circuit 12 is at least 90 degrees around the periphery of the center of each magnet unit projection 5. Specifically, the track of the conductive circuit 12 is distributed around the periphery of the center of the magnet unit projection 5. In order to better arrange the entire circuit structure in series, the conductive circuit 12 does not completely surround the periphery of the center of the projection, but is distributed within an angle range of the periphery of the center of the magnet unit projection 5, and the angle range is [90 degrees-360 degrees]. In a specific implementation, for example, the conductive circuit segment 12c in FIG. 5, it surrounds the periphery of the center of the magnet unit projection 5 by about 120 degrees. In addition, the angle range of the conductive circuit 12 distributed around the periphery of the center of the different magnet unit projections 5 is the same or different.

[0132] In the technical solution provided in the application, the conductive circuit 12 is sequentially projected on at least part of the area around the center of each magnet unit according to the change of the magnetic field distribution when the diaphragm 1 vibrates, thereby effectively improving the utilization efficiency of the magnet field by the conductive circuit 12. Specifically, referring to FIGS. 3 and 4, the dashed arrows in the figures represent the direction of the magnetic induction lines generated by the magnet unit 4. The magnet units 4 arranged oppositely form an effective magnetic field around the magnet units 4. By sequentially projecting the conductive circuit 12 on at least part of the area around the center of each magnet unit, that is, the conductive circuit 12 is distributed on the diaphragm 1 in the area enclosed by the dashed lines in FIGS. 3 and 4, the conductive circuit 12 tries to make full use of the magnetic field around the magnet unit 4. According to the simulation result of the magnetic field, the position and width of the conductive circuit 12 are adjusted, so that when the diaphragm 1 vibrates, the force acting on each part of the conductive circuit 12 is stable. Correspondingly, referring to FIG. 5, after the conductive circuit 12 is sequentially projected on at least part of the area around the center of each magnet unit, the conductive circuit 12 with different widths is distributed around each magnet unit 4. For example, the conductive circuit 12 in the area enclosed by the oval dashed lines A, B, C, D and E in FIG. 5 is arranged according to the trend of the magnetic field around the magnet unit 4 when the diaphragm 1 vibrates, which can effectively utilize the magnetic field around the magnet unit 4, and thus the vibration effect and sound quality of the diaphragm 1 are better.

[0133] Referring to FIGS. 2 and 5, in one embodiment provided in the application, when the track of the conductive circuit 12 sequentially surrounds the periphery of the center of one magnet unit projected in FIG. 5 multiple times, the width or cross-sectional area of the conductive circuit 12 is different under different surrounding times. Alternatively, the width or cross-sectional area of the conductive circuit 12 on different areas of the diaphragm 1 is different. As shown in FIG. 5, the direction of the arrow is the extension direction of the conductive circuit 12. It can be seen that the conductive circuit 12 extends from the periphery of the center of the magnet unit projected in FIG. 5 on one end of the magnetic system to the periphery of the center of the magnet unit projected in FIG. 5 on the other end of the magnetic system. Specifically, the conductive circuit 12 starts from the periphery of the center of one magnet unit projected in FIG. 51 on the first magnet group 2 at the head of the magnetic system (point M in FIG. 5), then sequentially surrounds the periphery of the center of each magnet unit projected in FIG. 5 on the same side of the magnetic system along the arrangement direction of the magnet group 2 (arrow X direction), then extends from the periphery of the center of one magnet unit projected in FIG. 52 on the last magnet group 2 at the end of the magnetic system to the periphery of the center of another magnet unit projected in FIG. 53 on the last magnet group 2 at the end of the magnetic system, then sequentially surrounds the periphery of the center of each magnet unit projected in FIG. 5 on the same side of the magnetic system along the arrangement direction of the magnet group 2, then the conductive circuit 12 reenters the periphery of the center of one magnet unit projected in FIG. 54 on the first magnet group 2 at the head of the magnetic system from the periphery of the center of another magnet unit projected in FIG. 51 on the first magnet group 2 at the head of the magnetic system, and the process is repeated, thereby realizing multiple surrounding of the periphery of the center of the magnet unit projected in FIG. 5. Finally, the end point of the conductive circuit 12 is point N in FIG. 5, and the position of point N is near the magnet unit projected in FIG. 54.

[0134] For example, in the area A of the ellipse dashed line in Fig. 5, the width of the conductive circuit 12a at the outermost periphery of the projection center of the magnet unit 4 is the widest when the conductive circuit 12 surrounds the projection center of the magnet unit 4 for multiple times. This design not only controls the total resistance value of the conductive circuit 12, but also balances the force on different areas of the diaphragm 1. Specifically, the magnetic field strength of the conductive circuit 12 at the outermost side changes greatly when the diaphragm vibrates. In order to maintain the smooth force on the diaphragm 1 during vibration, appropriately widening the width of the circuit in this area can reduce the difference in the magnetic field strength at this position during vibration. Moreover, since the length of the conductive circuit 12 at the outermost side is longer than that of the conductive circuit 12 at the inner side, widening the conductive circuit 12 at the outermost side can effectively reduce its resistance value, and the entire conductive circuit 12 can surround the projection center of the magnet unit 4 for multiple times at a fixed resistance value, thereby effectively improving the utilization of the magnetic field. In addition, since the magnetic field strength at different positions in the opposing gap 10 is different, the magnetic field strength at different positions on the same diaphragm 1 plane changes differently, which causes the force on the diaphragm 1 at different positions to change during vibration. Therefore, in the technical solution of the present application, the width of the conductive circuit 12 at different positions of the diaphragm 1 is calculated by simulating the change rule of the magnetic field strength, so that the force on the conductive circuit 12 during vibration of the diaphragm 1 to different positions is optimized to be relatively stable. In the technical solution provided in the present application, the conductive circuit 12 can be a thin layer-shaped circuit with different widths.

[0135] Further, in one embodiment provided in the present application, the conductive circuit 12 is in an S-shaped structure along the length direction of the diaphragm 1 and sequentially surrounds the projection diagram of the plurality of magnet units 4. For adjacent magnet units 4, the conductive circuit 12 is located at different sides of the magnet unit projection diagram 5. Specifically, referring to Fig. 5, for the magnet unit projection diagram 55, the conductive circuit 12 is located at the right side of the magnet unit projection diagram, for the magnet unit projection diagram 56 adjacent to it, the conductive circuit 12 is located at the left side of the magnet unit projection diagram, and for the magnet unit projection diagram 57 adjacent to the magnet unit projection diagram 56, the conductive circuit 12 is located at the right side of the magnet unit projection diagram, and so on. In the arrangement direction of the magnet group 2, the conductive circuit 12 is located at different sides of the corresponding magnet unit projection diagram 5 between adjacent magnet units 4 in the same magnet column. For the magnet unit projection diagram 57 and the magnet unit projection diagram 58, i.e., two magnet unit projection diagrams 5 in the same magnet group, the conductive circuit 12 is located at the same side of the magnet unit projection diagram 5.

[0136] Generally, the M points and the N points of the conductive circuit 12 are used to connect audio controllers, and the output audio current can enter the conductive circuit 12 from the M points, then flow along the extension direction of the conductive circuit 12, and finally flow out from the N points. Of course, the audio current can also enter from the N points and flow out from the M points. In this way, the current flow direction in the conductive circuit 12 shows regularity, that is, the current in the conductive circuit around the adjacent magnet unit projection diagram flows in the opposite direction with the magnet unit projection diagram as the center. Taking the direction of the current flowing into the M points as an example, for the conductive circuit 12 around the magnet unit projection diagram 56, the current in the conductive circuit 12 flows clockwise, while for the conductive circuit 12 around the magnet unit projection diagram 57 which is longitudinally adjacent to the magnet unit projection diagram 56, the current in the conductive circuit 12 flows counterclockwise. For the conductive circuit 12 around the magnet unit projection diagram 58 which is transversely adjacent to the magnet unit projection diagram 57, the current in the conductive circuit 12 again flows clockwise. According to the magnetic field direction, it can be concluded that the force direction of the conductive circuit 12 around the magnet unit projection diagram is consistent, and the entire diaphragm 1 will vibrate in the same direction at the same time. That is, for the magnet pairs with different opposite magnetic poles, the current around the magnet unit projection diagram 5 flows in the opposite direction. If the direction of the current flowing into the M points is changed, the direction of the current in the conductive circuit 12 will also change to the opposite direction at the same time, and the entire diaphragm 1 will vibrate in the opposite direction.

[0137] Generally, the conductive circuit 12 is bonded to the support layer 11 by glue. For example, in a specific implementation, the support layer 11 is an EVA (Ethylene Vinyl Acetate Copolymer) layer which has certain rigidity and toughness and can effectively support the diaphragm 1. The EVA layer is provided with a metal layer such as an aluminum foil. Generally, glue can be brushed on the EVA layer, and then the aluminum foil layer is bonded to the surface of the EVA layer. The surface of the aluminum foil layer is provided with the conductive circuit 12. After the conductive circuit 12 is powered, the entire diaphragm 1 can be driven to vibrate. The specific material of the support layer 11 of the diaphragm 1 is not limited in the present application. For example, the material of the support layer 11 includes but is not limited to plastic sheets, thin wood boards, carbon fiber sheets, hard paper boards, metal sheets, polymer material boards, composite material boards, etc. In addition, the support layer 11 can also be some light insulating materials, such as nylon mesh covered with an adhesive layer, thin rubber, thin silicone, polymer glue layer, fiber cloth, double-sided adhesive, etc. In addition, the material of the metal film includes but is not limited to aluminum, gold, silver, aluminum-magnesium alloy, copper, etc.

[0138] Further, the conductive circuit 12 can be arranged on one side of the support layer 11, or both sides of the support layer 11 can be provided with the conductive circuit 12. Further, the front and / or back of the support layer 11 can be provided with multiple layers of conductive circuit 12, and the conductive circuit 12 in each layer is insulated by adhesive. In a specific embodiment, the front and back of the support layer 11 are respectively provided with a layer of conductive circuit 12, and the conductive circuit 12 on the front is the same shape as the conductive circuit 12 on the back. The conductive circuit 12 on the front and the conductive circuit 12 on the back are arranged in opposite directions, and the conductive circuit 12 on the front can be connected in series or in parallel with the conductive circuit 12 on the back. Alternatively, the two circuits can be independent of each other and powered by different audio current output devices, but it is necessary to ensure that when the current passes through different conductive circuits 12 around the projection of the same magnetic unit, the current direction in the conductive circuit 12 on the front and back of the support layer 11 needs to be consistent, that is, clockwise at the same time or counterclockwise at the same time, so that the force direction of each part of the circuit is consistent, and the entire diaphragm 1 vibrates more stably. Further, in another specific embodiment, the front and back of the support layer 11 are respectively provided with two layers of conductive circuit 12, and the two layers of conductive circuit 12 on the same side of the support layer 11 are insulated by adhesive. The two layers of circuit can be connected in series or in parallel by welding, and the conductive circuits on both sides of the support layer 11 also comply with the principle that the current direction on the same projection of the magnetic unit is consistent.

[0139] In an embodiment provided in the present application, the conductive circuit 12 can be directly bonded to the support layer 11, or a metal film can be pasted on the surface of the support layer 11, and then the conductive circuit 12 is formed on the metal film by etching or laser engraving. The conductive circuit 12 is insulated from other areas of the metal film. When the front and back of the support layer 11 are both provided with the conductive circuit 12, the front and back of the support layer 11 are respectively covered with a metal film in areas other than the areas where the conductive circuit 12 is located, and the metal film is insulated from the conductive circuit 12. Covering the metal film on the non-conductive circuit 12 area of the support layer 11 not only improves the structural strength of the diaphragm 1, but also facilitates the processing and manufacturing of the diaphragm 1.

[0140] Further, in an embodiment provided by the present application, the metal film on the front surface of the support layer 11 is folded from the edge of the support layer 11 to the back surface of the support layer 11. Specifically, when the metal film and the conductive circuit 12 are provided on both the front surface and the back surface of the support layer 11, a complete metal film can be folded in half and then attached to the front surface and the back surface of the support layer 11 respectively. For example, referring to FIG. 6, the dotted line represents the folding line of the metal film. For the above technical solutions, the conductive circuit 12 can be processed on the metal film first and then attached to the support layer 11, or the metal film can be attached to the support layer 11 first and then the conductive circuit 12 is processed. The processing of the conductive circuit 12 includes but is not limited to etching, mechanical processing, laser engraving, etc.

[0141] It should be noted that the conductive circuit 12 on the front surface of the support layer 11 and the conductive circuit 12 on the back surface of the support layer 11 are not mirror symmetrical based on the folding line. The conductive circuit 12 on the front surface of the support layer 11 and the conductive circuit 12 on the back surface of the support layer 11 are rotationally symmetrical about the longitudinal axis of the diaphragm 1. The conductive circuit 12 on the front surface of the support layer 11 is rotated 180° to obtain the conductive circuit 12 on the back surface of the support layer 11.

[0142] Referring to FIG. 7, in an embodiment provided by the present application, the diaphragm 1 further includes a rib structure 6, as shown by the dotted line in FIG. 7, which includes a transverse rib 61. The rib structure 6 is provided in the support layer 11, for example, the rib structure 6 is located in the structure of the support layer 11, similar to the skeleton of the support layer 11, thereby enhancing the toughness and stiffness of the support layer 11. Alternatively, the rib structure 6 is attached to the front surface or the back surface of the support layer 11. Before the metal film is attached to the support layer 11, the rib structure 6 is first attached to the surface of the support layer 11, and then the metal film is attached. The rib structure 6 includes but is not limited to carbon fiber tubes, plastic tubes, wooden rods, metal wires, etc. or composite materials folded into some kind of bending-resistant structure, and the cross section of the bending-resistant structure includes but is not limited to T-shaped, triangular, semicircular, etc. In a specific implementation, the transverse rib 61 is provided in the gap corresponding to the different magnet unit projection diagrams. The rib structure 6 mentioned above can be provided in the support layer 11, of course, the rib structure 6 can also be attached to the surface of the diaphragm 1, in which case the rib structure 6 can be considered as a convex rib on the diaphragm 1. The transverse rib 61 provided in the gap corresponding to the different magnet unit projection diagrams can effectively avoid the convex rib affecting the amplitude of the diaphragm.

[0143] In one embodiment of the present application, a loudspeaker assembly is also provided, which comprises a magnetic system and a diaphragm 1 arranged in a same-pole opposite manner, the magnetic system comprises a plurality of magnet groups 2, each of the magnet groups 2 comprises two magnet pairs, for example, the first magnet pair 21 and the second magnet pair 22 in FIG. 1, each of the magnet pairs comprises two same-pole opposite arranged magnet units 4, each of the magnet pairs can also be considered as a pair of magnet units, in the direction of arrow X in FIG. 1, the different magnet pairs are arranged in a spaced manner and the magnetic poles are opposite. The diaphragm 1 is located in the opposite gap 10 of the plurality of pairs of magnet units 4, the direction of arrow Y in FIG. 1 can be considered as the width direction of the opposite gap, and the width direction of the diaphragm 1 is perpendicular to the width direction of the opposite gap 10. In the direction of arrow Z in FIG. 1, the plurality of magnet groups 2 are arranged in a spaced manner, and the magnetic poles of the adjacent magnet groups are opposite.

[0144] Further, the loudspeaker assembly further comprises a support, and the plurality of magnet units 4 are arranged on the support, which can be understood as the support is used to fix the positions between the plurality of magnet units 4. When the diaphragm 1 vibrates, it needs to be located in the opposite gap 10 at all times, and the loudspeaker assembly further comprises an elastic suspension assembly, one end of the elastic suspension assembly is connected to the diaphragm 1, and the other end is connected to the support.

[0145] In another embodiment of the present application, a loudspeaker device is also provided, which comprises an acoustic body and at least one loudspeaker assembly described above, and the loudspeaker assembly is arranged on the acoustic body. The acoustic body is provided with a receiving space, and the loudspeaker assembly is connected in the receiving space, and the sound waves emitted by the loudspeaker assembly can be transmitted out through the opening of the receiving space. One loudspeaker assembly can be arranged in the acoustic body, or a plurality of loudspeaker assemblies can be arranged in the acoustic body, and the plurality of loudspeaker assemblies can be connected in series, or can be connected in parallel or in different circuits, which can be understood as different conductive circuits 12 are connected with different audio current output devices.

[0146] In summary, in the technical scheme provided in the embodiments of the present application, by projecting the conductive circuit around the plurality of regions outside the center of the projection diagram of each magnet unit in turn, the utilization efficiency of the magnetic field of the magnet by the conductive circuit is effectively improved. In addition, by optimizing the structure of the conductive circuit on the diaphragm, the total harmonic distortion of the loudspeaker can be effectively reduced.

[0147] The inventor of the present application analyzes the sound production principle of the acoustic device. In the prior art, the planar diaphragm acoustic device relies on a pair of longitudinal single supports to support the magnet column in a column to form a magnet column pair. Due to the large longitudinal dimension, the magnet support supporting the magnetic field is slowly deformed under long-term stress, the position of the magnet changes, and the distance between the magnet pair at the constraint end and the magnet pair far away from the constraint end changes, thereby causing the magnetic field strength to be non-uniform and changing the sound production state of the acoustic device.

[0148] In addition, according to the nature of sound propagation, when sound encounters an object during propagation, reflection, refraction, diffraction, and diffraction phenomena occur, and the size, shape, and distance of the obstacle encountered by the sound wave determine the direction and intensity of the sound propagation. For example, when the wavelength of the sound wave is more close to the size of the obstacle, or the wavelength of the sound wave is smaller than the size of the obstacle, the diffraction phenomenon is more obvious. If the size of the obstacle is much larger than the wavelength, the sound wave will be reflected like encountering a hard boundary, rather than obvious diffraction. At the receiving point, if the phase difference between the sound wave after diffraction and the sound wave without diffraction is 180 degrees, a wave trough will be generated at this position, and a wave peak will be generated when the phase difference is 0. Therefore, the influence of a single-layer support with different thickness on a certain frequency point can be calculated, thereby solving the problem of sound wave superposition and cancellation.

[0149] In addition, when the frequency of the sound wave is the same as the natural frequency of the sound support frame supporting the diaphragm, the sound wave will excite the sound support frame, thereby exciting the vibration of the sound support frame, causing resonance, and the sound support frame resonance will also emit sound. The resonance sound will interfere with the sound emitted by the diaphragm, causing total harmonic distortion, and thus affecting the quality of the sound of the sound.

[0150] Therefore, the sound support frame supporting the diaphragm needs to have a diaphragm accommodating hole allowing the diaphragm to pass through and allowing the diaphragm to have a certain vibration amplitude. At least one pair of open magnetic body mounting grooves are arranged at intervals on the two side walls of the diaphragm accommodating hole along the length direction. At least one pair of same-pole opposite magnetic bodies are arranged in the corresponding diaphragm accommodating hole to ensure the consistency of the sound single-layer support supporting the magnetic body, that is, to ensure the consistency of the opposite gap.

[0151] The stability of the opposite gap determines the uniformity of the magnetic field in which the diaphragm is located, thereby ensuring the stability of the sound emitted by the diaphragm. Then, the inventors of the present application improve the shape of the diaphragm accommodating hole wall of the sound single-layer support, the width of the diaphragm accommodating hole, and the size of the sound support frame shielding the diaphragm according to the characteristics of sound, so that the influence of the sound after diffraction and reflection is dispersed at different frequency points to obtain a wide frequency domain more stable sound pressure level, thereby avoiding obvious enhancement or cancellation at a certain frequency point. In addition, by changing the natural frequency of the sound support frame, the sound wave frequency emitted by the diaphragm is avoided to coincide with the natural frequency of the sound support frame, and the sound support frame resonance is avoided to solve the problem of total harmonic distortion.

[0152] Please refer to FIG. 1B, the embodiment of the present application provides a sound frame 1B for supporting a diaphragm 2B and a magnet 30B. The sound frame 1B comprises a plurality of spaced-apart sound single-layer supports 10B, and a spacing column 20B for connecting two adjacent sound single-layer supports 10B. The spacing column 20B can facilitate air flow and facilitate the sound emitted by the diaphragm 2B to be transmitted to the outside world.

[0153] Next, the sound single-layer support 10B will be described in detail in combination with FIGS. 2B-6B.

[0154] In the embodiment of the present application, please refer to FIGS. 2B-6B, the sound single-layer support 10B comprises at least one support plate 11B, and the support plate 11B is provided with a diaphragm accommodating hole 12B. Along the length direction of the diaphragm accommodating hole 12B, at least one pair of opposite magnet installation grooves 13B are symmetrically arranged on the side walls on both sides of the diaphragm accommodating hole 12B. The two magnet installation grooves 13B have an opposite gap therebetween. At least one pair of magnets 30B are symmetrically accommodated in the corresponding magnet installation grooves 13B, and the magnets 30B are same-pole opposite. Thus, the opposite gap distance of each pair of magnets 30B along the height direction of the sound frame 1B is consistent. The diaphragm 2B is located at the opposite gap in the diaphragm accommodating hole 12B. The conductive circuit on the diaphragm 2B is located in the magnetic field generated by the opposite magnets 30B. When an electric current passes through the conductive circuit, a magnetic force acting on the conductive circuit is generated, thereby driving the diaphragm 2B to vibrate and emit sound. In a specific embodiment, as shown in FIG. 6B, the width of the diaphragm accommodating hole 12B at different positions around the magnet installation groove 13B is the same. In this case, for the frequency whose half wavelength is equal to the thickness of the sound single-layer support 10B, the sound single-layer support 10B is affected. Once the thickness of the sound single-layer support 10B is less than a certain value, such as 8.5 mm, the corresponding wavelength is 17 mm, and the sound wave frequency corresponding to the wavelength of 17 mm is 20 kHz, which is beyond the human hearing range (20 Hz-20 kHz). The influence of reflection or diffraction can be ignored, and the final sound pressure level curve can be stable in the full audio range. In another embodiment of the present application, as shown in FIGS. 2B-7B, the width of the diaphragm accommodating hole 12B at different positions around the magnet installation groove 13B is different, that is, the hole walls on both sides of the diaphragm accommodating hole 12B are not parallel. When the sound waves emitted by the diaphragm 2B meet the hole walls at different positions of the diaphragm accommodating hole 12B, diffraction and reflection of sound waves of different frequencies are generated, so that when the audio receiving point is measured, the sound pressure level at the position is not stable due to the superposition or cancellation of a certain frequency, so as to ensure good sound effect.

[0155] Further, in some embodiments, referring to FIGS. 2B-5B, for the different widths of the diaphragm accommodating hole 12B at different positions, some of the achievable structures of the diaphragm accommodating hole 12B are that the hole walls of the diaphragm accommodating hole 12B at opposite sides of the magnet mounting slot 13B are different in shape along the length direction of the diaphragm accommodating hole 12B, so that the distances from the diaphragm 2B are different at different positions, so that the same audio is not superimposed or cancelled at the same position. For example, the hole walls of the diaphragm accommodating hole 12B at the sides of the magnet mounting slot 13B are symmetrical relative to the diaphragm accommodating hole 12B parallel to the midplane of the diaphragm 2B, and the hole walls of the diaphragm accommodating hole 12B are bevels, wavy shapes, M shapes, arc shapes, S shapes, or any irregular shapes.

[0156] Of course, the hole walls of the diaphragm accommodating hole 12B at the two sides along the thickness direction of the acoustic single-layer support 10B can also be bevels, or other regular or irregular shapes, as long as they are not parallel to the diaphragm 2B, and the present embodiment is not specifically limited.

[0157] Referring to FIGS. 4B and 5B, for the different widths of the diaphragm accommodating hole 12B at different positions, some of the achievable structures of the diaphragm accommodating hole 12B are that the hole walls of the diaphragm accommodating hole 12B at different positions at the sides of the magnet mounting slot 13B are different in shape, so as to ensure that the hole walls of the diaphragm accommodating hole 12B at the two sides are not parallel.

[0158] Specifically, please refer to FIG. 4B and FIG. 5B, the acoustic single-layer support 10B includes a plurality of support plates 11B which are sequentially laminated and bonded, and each support plate 11B is located at the hole wall of the diaphragm accommodating hole 12B around the magnet mounting groove 13B. For example, along the length direction of the diaphragm accommodating hole 12B, the hole wall on both sides of the diaphragm accommodating hole 12B on some support plates 11B is a slope which gradually widens from the magnet mounting groove 13B towards the both ends of the diaphragm accommodating hole 12B, and the angle of the hole wall of the diaphragm accommodating hole 12B on different support plates 11B is different. The hole wall on both sides of the diaphragm accommodating hole 12B on other support plates 11B is symmetrical relative to the median plane of the diaphragm 2B, and the hole wall on one side of the diaphragm accommodating hole 12B is taken as an example for illustration, the hole wall of the diaphragm accommodating hole 12B around the magnet mounting groove 13B is a curve shape, M shape or arc shape, etc. The hole wall on both sides of the diaphragm accommodating hole 12B around the magnet mounting groove 13B on some other support plates 11B is irregular. The acoustic single-layer support 10B can be a random lamination of the support plates 11B with the above-mentioned shapes, or the support plates 11B with the diaphragm accommodating hole 12B of one shape can have multiple, and the support plates 11B with the same shape of the diaphragm accommodating hole 12B are interspersed with the support plates 11B with the diaphragm accommodating hole 12B of another shape, and the embodiments of the present application do not make specific limitations as long as the width of the diaphragm accommodating hole 12B at different positions around the magnet mounting groove 13B is different. The structure of the sequentially laminated and bonded multiple support plates 11B can greatly improve the resonance of the single-layer support plate 11B when the diaphragm 2B vibrates to produce sound, and can also reduce the difficulty of manufacturing the hole wall of the diaphragm accommodating hole 12B and save costs.

[0159] Further, in some embodiments of the present application, the support plate 11B is a metal plate, which has high rigidity and high natural frequency, and when the diaphragm 2B vibrates, resonance occurs to produce distortion. The adjacent two support plates 11B are connected by bonding, and the bonding glue between the adjacent two support plates 11B can change the natural frequency of the acoustic single-layer support 10B as a whole, thereby avoiding the occurrence of resonance. From one perspective, the resonance frequency of metal is high, and the glue layer can absorb the vibration energy of the metal when the metal resonates, thereby eliminating the resonance. In another embodiment of the present application, the support plate 11B is selected to be a material with certain strength and low resonance frequency, such as acrylic plate, carbon fiber plate, etc., and the material selection has a relatively wide selection, and the embodiments of the present application do not make specific limitations.

[0160] In order to further prevent the vibration of the sound single-layer support 10B, in some embodiments of the present application, the sound single-layer support 10B further comprises a buffer, the buffer is arranged between two adjacent support plates 11B, and the buffer can absorb vibration. When the support plate 11B is affected by sound and vibrates, the buffer can absorb the vibration to change the vibration frequency of the entire sound single-layer support 10B to avoid resonance.

[0161] It should be noted that the minimum value of the width of the diaphragm accommodating hole 12B in the embodiments of the present application is greater than or equal to the width of the opposing gap, which can ensure that the diaphragm 2B has enough space to vibrate and avoid collision between the diaphragm 2B and the hole walls on both sides of the diaphragm accommodating hole 12B when the diaphragm 2B vibrates.

[0162] Since the magnet 30B has a certain height, in some embodiments of the present application, when the sound single-layer support 10B is one support plate 11B, in order to make the magnet mounting groove 13B have enough height to accommodate the magnet 30B, the thickness of the sound single-layer support 10B is greater than the height of the magnet 30B. When the sound single-layer support 10B is two support plates 11B stacked and bonded, at the magnet mounting groove 13B, the upper and lower support plates 11B are provided with inner grooves in the direction away from each other, and the depth of the inner grooves is less than the thickness of the single-sided plate wall of the support plate 11B. The upper and lower support plates 11B are mutually engaged to form the magnet mounting groove 13B. When the sound single-layer support 10B is a plurality of support plates 11B stacked, taking the position of the magnet mounting groove 13B as a reference, along the height direction of the sound single-layer support 10B, the support plates 11B at the top and the bottom are provided with no inner grooves at the position of the magnet mounting groove 13B to form the upper groove wall and the lower groove wall of the magnet mounting groove 13B, and the support plates 11B in the middle are provided with grooves of the same shape at the position of the magnet mounting groove 13B. When the plurality of support plates 11B are stacked and bonded together, a one-side-opened magnet mounting groove 13B is formed.

[0163] In order to ensure the strength of the magnetic field, in some embodiments of the present application, the height of the magnet 30B is large, so that the thickness of the acoustic single-layer support 10B accommodating the magnet 30B is too thick, and the thicker the acoustic single-layer support 10B is. It can be understood that the wavelength of high-frequency sound waves is short, and after encountering obstacles, diffraction or reflection will occur, and superposition or cancellation will occur at the listening position, thereby causing the sound pressure level to increase or decay at a certain frequency. The acoustic single-layer support 10B in the embodiment of the present application is an obstacle, and the thicker the acoustic single-layer support 10B is, the greater the influence on the frequency response curve is, and the more unfavorable the sound quality of the acoustic is. Therefore, in some embodiments of the present application, the thickness of the acoustic single-layer support 10B located at the peripheral side portion of the magnet mounting groove 13B is smaller than the thickness of the acoustic single-layer support 10B located at the magnet mounting groove 13B. Since the magnet mounting groove 13B needs to accommodate the magnet 30B, the thickness of the acoustic single-layer support 10B located at the magnet mounting groove 13B is greater than the thickness of the magnet 30B, and the thickness of the acoustic single-layer support 10B located at the peripheral side portion of the magnet mounting groove 13B can be smaller than the thickness of the magnet 30B, thereby reducing the ability of the acoustic single-layer support 10B to hinder the middle and high frequency sound waves.

[0164] In some embodiments of the present application, for the acoustic single-layer support 10B formed by laminating and bonding a plurality of support plates 11B, the shapes of the peripheral sides of the support plates 11B of different layers can be different. For example, on the outer periphery of the acoustic single-layer support 10B, the support plates 11B of different layers are in a stepped staggered structure, and along the thickness direction of the acoustic single-layer support 10B, the stepped staggered structures of the upward inclined type and the downward inclined type are sequentially arranged in an alternating manner from bottom to top. The present application does not make specific limitations on the embodiments.

[0165] In order to facilitate understanding of the structure of the magnet mounting groove 13B and the reason for the position setting of the diaphragm 2B in the acoustic support 1B, first, the sound production principle of the diaphragm 2B is described.

[0166] Generally, the magnet 30B has N (North) and S (South) poles, and the same-pole opposite arrangement herein refers to the opposite arrangement of the two magnets 30B, and the same polarity of the opposite poles. The opposite poles are not attached to each other, but have a certain gap to form an effective magnetic field. Please refer to FIG. 7B.

[0167] The diaphragm 2B is arranged in the opposite gap, and the conductor is arranged on the diaphragm 2B, and the peripheral side of the projection of the magnet 30B on the diaphragm 2B is located on both sides of the diaphragm 2B, so as to ensure that the conductor is located in the magnetic field with the best strength and stability. When the current passes through the conductor, the conductor will be affected by the magnetic field force, so that the conductor drives the diaphragm 2B to vibrate to produce sound.

[0168] Further, referring to FIG. 3B, a spacing slot 14B can be provided between the adjacent slot walls of two adjacent magnet mounting slots 13B. The slot bottom wall of the spacing slot 14B can be a flat surface parallel to the diaphragm 2B, can be a slanted surface with a certain angle, or can be one of a V-shaped surface, an M-shaped surface, an arc-shaped surface, a wavy surface, etc.

[0169] It can be understood that the magnet 30B not only generates a magnetic field at the opposite gap, but also generates a magnetic field on the side away from the opposite gap. For the purpose of understanding and description, the magnetic field at the opposite gap is referred to as the front magnetic field, and the magnetic field generated on the side away from the opposite gap is referred to as the back magnetic field. In order to reduce the weakening of the front magnetic field caused by the short circuit of the back magnetic field and the front magnetic field, in some embodiments of the present application, referring to FIG. 2B and FIG. 3B, two magnets 30B with opposite magnetic poles are respectively mounted in two adjacent magnet mounting slots 13B on the same side. Specifically, the internal magnetic field direction of the magnet 30B is perpendicular to the diaphragm 2B, one of the magnets 30B has a magnetic pole N facing the diaphragm 2B, and the other magnet 30B has a magnetic pole S facing the diaphragm 2B. Two magnet mounting slots 13B on one side of the diaphragm accommodating hole 12B have openings on the side away from the magnet mounting slots 13B, and the openings are connected to each other to form an accommodating space 15B. A magnetically conductive member 40B is arranged in the accommodating space 15B. The side of the magnet mounting slot 13B away from the opening is covered by at least a portion of the magnetically conductive member 40B, that is, the magnetically conductive member 40B penetrates the two magnet mounting slots 13B. When the two magnets 30B with opposite magnetic poles are placed in the magnet mounting slots 13B, they can be attracted to the magnetically conductive member 40B, and the back magnetic field can be conducted in the magnetically conductive member 40B, thereby reducing the short circuit with the front magnetic field. In addition, as shown in FIG. 2B, the magnetically conductive member 40B cannot move in the direction of the width of the acoustic single-layer support 10B under the limitation of the slot walls between the two adjacent magnet mounting slots 13B, and the attraction between the magnet 30B in the magnet mounting slot 13B and the magnetically conductive member 40B also limits the movement of the magnetically conductive member 40B in the direction of the length of the acoustic single-layer support 10B. The same-pole opposite magnets 30B designed in position repel each other, so that the magnet 30B can stably be in the magnet mounting slot 13B. At the same time, the magnetically conductive member 40B also limits the position of the magnet 30B in the magnet mounting slot 13B, so as to ensure that neither the magnetically conductive member 40B nor the magnet 30B is displaced. In order to further limit the position between the magnet 30B and the magnetically conductive member 40B, the magnet 30B and the magnetically conductive member 40B are adhered to the magnet mounting slot 13B or the accommodating space 15B by adhesive.

[0170] In order to facilitate the installation of the magnetic member and the magnetic conductive member 40B, in some embodiments of the present application, referring to FIG. 2B, the upper end of the at least one magnet installation slot 13B communicates through the upper side of the single-layer sound support 10B along the width direction of the single-layer sound support 10B to form an installation hole, or the upper side of the accommodating space 15B penetrates through the single-layer sound support 10B to form an installation hole, the magnetic conductive member 40B and the magnet 30B are installed through the installation hole, or the magnetic conductive member 40B is installed in the accommodating space 15B through the installation hole formed by the upper side of the accommodating space 15B penetrating through the single-layer sound support 10B, and the magnet 30B is installed in the magnet installation slot 13B from the opening of the magnet installation slot 13B and is attracted to the magnetic conductive member 40B through the side of the magnet installation slot 13B away from the opening to limit the position. As long as the position of the magnetic conductive member 40B and the magnet 30B can be limited, the present embodiment is not specifically limited. Further, the single-layer sound support 10B further comprises a cover plate 16B, which is movably arranged on the installation hole to open or block the installation hole, so as to facilitate the taking and placing of the magnet 30B and the magnetic member, and the cover plate 16B and the single-layer sound support 10B can be connected by gluing.

[0171] In some embodiments of the present application, referring to FIGS. 2B-3B, the at least one pair of opposite corners of the diaphragm accommodating hole 12B on the support plate 11B are provided with a diaphragm suspension structure 17B to suspend the diaphragm 2B. In order to fix the diaphragm 2B in the corresponding position and provide a certain restoring force when vibrating, the diaphragm 2B is suspended on each single-layer sound support 10B of the sound support 1B by an elastic suspension assembly, one end of which is connected to the diaphragm 2B and the other end is connected to the diaphragm suspension structure 17B. Specifically, when the diaphragm 2B is displaced by the magnetic field force, the elastic suspension assembly is stretched, and when the magnetic field force is removed, the restoring force generated by the elastic suspension assembly enables the diaphragm 2B to return to the initial position. It can be that the diaphragm suspension structure 17B is provided at the four corners of the diaphragm accommodating hole 12B, or it can be that the diaphragm suspension structure 17B is provided at two corners of one pair of opposite diagonal lines of the diaphragm accommodating hole 12B of one single-layer sound support 10B, and the diaphragm suspension structure 17B is provided at two corners of another pair of opposite diagonal lines of the diaphragm accommodating hole 12B of the adjacent single-layer sound support 10B, or it can be that at least one pair of diaphragm suspension structures 17B are oppositely arranged on the two width direction hole walls of the diaphragm accommodating hole 12B, as long as the diaphragm 2B can be stably suspended, and the present embodiment is not specifically limited.

[0172] The embodiment also provides a sound equipment, as shown in Fig. 1B, which comprises a sound frame 1B, the sound frame 1B is connected by a plurality of sound single-layer supports 10B arranged at intervals through a screw rod in a stud spacing manner, at least one pair of magnets 30B, and a diaphragm 2B, the at least one pair of magnets 30B are symmetrically installed in a magnet installation slot 13B of the sound single-layer support 10B in a same-pole opposite manner to form a stable magnetic field, the diaphragm 2B is arranged in a diaphragm accommodating hole 12B of each layer of the sound single-layer support 10B, and a conductor on the diaphragm 2B is located at a circumferential side of a projection of the magnet 30B on the diaphragm 2B, when a current passes through the conductor, the conductor can be affected by the magnetic field to be converted into vibration of the conductor, so that sound is emitted.

[0173] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
