Description

Technical Field

[0001] This invention relates to the field of loudspeaker technology, and more specifically to a planar coil diaphragm loudspeaker and its assembly device. Background Technology

[0002] The main structure of a planar coil diaphragm loudspeaker mainly includes an upper shell, a lower shell, an upper support ring, a lower support ring, a diaphragm, a radially magnetized magnetic ring, a vertical outer magnetic ring, a vertical inner magnetic ring, an upper conductor, and a lower conductor. For example, patent number CN212324346U discloses a planar coil diaphragm loudspeaker. In actual assembly, workers align and tighten each part one by one, and then fix it with screws. The whole process is quite cumbersome, especially in the alignment process, which lacks standardized assistance, has strong variability, and bending depends on the worker's experience and skill, greatly affecting assembly efficiency. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention proposes a planar coil diaphragm loudspeaker with a structure that facilitates assembly, and an assembly device for assembling the planar coil diaphragm loudspeaker with higher efficiency.

[0004] The technical solution of this invention is implemented as follows:

[0005] The first aspect of the present invention provides a planar coil diaphragm loudspeaker, comprising an upper housing, a lower housing, an upper support ring, a lower support ring, a diaphragm, a radially magnetized magnetic ring, a vertically outer magnetic ring, a vertically inner magnetic ring, an upper conductor, and a lower conductor. The upper housing, lower housing, upper support ring, lower support ring, and diaphragm are all configured as circular structures with the same outer diameter. The upper support ring and lower support ring clamp the diaphragm from both sides, and the upper housing and lower housing respectively clamp the upper support ring and lower support ring from both sides. The upper housing is provided with a screw that passes through the upper housing, upper support ring, diaphragm, and lower support ring in sequence and is threadedly connected to the lower housing. The inner surfaces of the upper housing and lower housing are provided with centrally symmetrically distributed locking posts. The vertically outer magnetic ring, vertically inner magnetic ring, and upper conductor are all fixed to the inner surface of the upper housing by the locking posts of the upper housing, and the radially magnetized magnetic ring and lower conductor are all fixed to the inner surface of the lower housing by the locking posts of the lower housing.

[0006] The second aspect of the present invention provides an assembly apparatus, applied to the assembly of the above-described planar coil diaphragm loudspeaker, comprising:

[0007] The base has an arc-shaped groove and a guide rail groove on both sides of its top.

[0008] A guide rail is provided in a guide rail groove, and the guide rail has a cuboid structure.

[0009] Each slide has one corresponding to the upper housing, lower housing, upper support ring, lower support ring, and diaphragm. The slides are arranged sequentially on the guide rail, with the lowest slide fixed along the length of the guide rail, while the remaining slides slide along the guide rail. A limit groove is provided on the top of each slide.

[0010] The slide includes a central support plate and a limiting plate that is vertically movable on the central support plate in a direction perpendicular to the upper surface of the base. The limiting groove is opened on the top of the limiting plate, and the top of the central support plate is inserted into the limiting groove to form the bottom part of the limiting groove.

[0011] The slide block that slides with the guide rail moves to the lowest slide block so that two adjacent slide blocks out of the five slide blocks fit together. The limiting plate moves downward so that the top of the middle support plate is exposed from the limiting groove.

[0012] It also includes a limiting rod, one of which is set on each side of the base. When the upper shell, lower shell, upper support ring, lower support ring and diaphragm are placed in the limiting groove, the two sides contact the limiting rod. The inner surface of the limiting rod is an arc surface.

[0013] Furthermore, the upstream and downstream ends of the guide rail are respectively provided with a push plate and a baffle, and the lower housing, lower support ring, diaphragm, upper support ring and lower housing are placed on each slide in sequence, with the push plate contacting the upstream end face of the lower housing and the baffle contacting the downstream end face of the upper housing.

[0014] Furthermore, the push plate includes a first circular portion that contacts the upstream end face of the lower housing and a second circular portion disposed on the upstream end face of the first circular portion. The size of the first circular portion is smaller than that of the second circular portion. The circumferential surface of the first circular portion contacts the top of the limiting plate below it. The circumferential surface of the second circular portion is flush with the circumferential surface of the lower housing. The upstream end face of the uppermost limiting plate is provided with a ""-shaped stop, and the bottom of the second circular portion is inserted into the stop.

[0015] Furthermore, a support ring is fixedly provided at the downstream end of the arc-shaped groove, a connecting ring is rotatably provided on the inner ring of the support ring, and the upstream end of the limiting rod is fixedly provided on the connecting ring. A sliding rod is inserted into the upstream end of the limiting rod, an operating plate is fixedly provided at the upstream end of the sliding rod, and a push rod is fixedly provided between the operating plate and the push plate.

[0016] Furthermore, the baffle has a diameter smaller than that of the upper housing end face, so that the screw holes on the upper housing are located outside the baffle.

[0017] Furthermore, the limiting plate is fitted onto the middle support plate from the top. Both sides of the middle support plate are provided with longitudinal sliders. The inner walls of both sides of the limiting plate are provided with longitudinally distributed longitudinal grooves. The longitudinal sliders are slidably disposed in the longitudinal grooves, and a support spring is provided between the top of the longitudinal slider and the inner top wall of the longitudinal groove.

[0018] Furthermore, both the bottom of the central support plate and the limiting plate are provided with guide rail grooves that are sleeved on the guide rail. The inner walls of the guide rail grooves of the central support plate that slides with the guide rail are provided with transverse sliders. Both sides of the guide rail are provided with transverse sliding grooves, and the transverse sliders are slidably disposed in their corresponding transverse sliding grooves. The central support plate at the lowest downstream side is fixedly disposed on the guide rail.

[0019] Furthermore, the five slide blocks are equidistantly distributed when the distance between two adjacent slide blocks is at its maximum value, and the upstream ends of the four transverse sliders respectively contact the inner wall of the upstream end of their corresponding transverse grooves.

[0020] Furthermore, a synchronizing rod assembly is provided between the sides of the limiting plates of two adjacent slides. The synchronizing rod assembly includes a first rod and a second rod, with the opposite ends of the first and second rods rotatably engaged. The opposite ends of the first and second rods are rotatably connected to the sides of two adjacent limiting plates, and the opposite ends of the first and second rods are provided with teeth. The teeth on the first and second rods on the same limiting plate side are in an interlocking state, and when the distance between two adjacent slides is at its maximum, the opposite ends of the first and second rods between the two adjacent slides are in a downward tilted state.

[0021] The present invention has the following beneficial effects:

[0022] 1. The planar coil diaphragm loudspeaker of the present invention has locking posts on the inner surfaces of the upper and lower housings, which facilitates fixing the vertical outer magnetic ring, the vertical inner magnetic ring and the upper conductor on the inner surface of the upper housing and fixing the radial magnetized magnetic ring and the lower conductor on the inner surface of the lower housing during the assembly process, thereby improving assembly efficiency.

[0023] 2. During use, after the upper shell, upper support ring, diaphragm, lower support ring and lower shell are placed, the push plate can be directly pushed to make the slide move in sequence, so as to realize the sequential fitting of the upper shell, upper support ring, diaphragm, lower support ring and lower shell, which greatly improves the assembly efficiency.

[0024] 3. The assembly device of the present invention configures the slide as a central support plate and a limiting plate that can be displaced in the height direction on the central support plate. A limiting groove supporting the upper shell, upper support ring, diaphragm, lower support ring, and lower shell is formed on the top of the limiting plate. Combined with the cooperation of the limiting groove and the central support plate, this allows for stable displacement of the lower shell, lower support ring, diaphragm, and upper support ring. Furthermore, while adjacent slides are in contact, the upper shell, upper support ring, diaphragm, lower support ring, and lower shell are exposed. The exposed lower shell, lower support ring, diaphragm, and upper support ring are then sequentially contacted by the translation of the tops of all slides in this state. This results in more convenient operation, more stable performance, and higher efficiency. Attached Figure Description

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 6 As shown, the first aspect of the present invention provides a planar coil diaphragm loudspeaker, comprising an upper housing 1, a lower housing 2, an upper support ring 3, a lower support ring 4, a diaphragm 5, a radially magnetized magnetic ring 6, a vertically outer magnetic ring 7, a vertically inner magnetic ring 8, an upper conductor 9, and a lower conductor 10. The upper housing 1, lower housing 2, upper support ring 3, lower support ring 4, and diaphragm 5 are all configured as circular structures with the same outer diameter. The upper support ring 3 and lower support ring 4 clamp the diaphragm 5 from both sides, and the upper housing 1 and lower housing 2 respectively clamp the upper support ring 9 from both sides. Ring 3 and lower support ring 4, and the upper housing 1 is provided with screws that pass through the upper housing 1, upper support ring 3, diaphragm 5 and lower support ring 4 in sequence and are threaded to the lower housing 2. The inner surfaces of the upper housing 1 and the lower housing 2 are provided with centrally symmetrically distributed locking pins 11. The vertical outer magnetic ring 7, the vertical inner magnetic ring 8 and the upper conductor 9 are all fixed to the inner surface of the upper housing 1 by the locking pins 11 of the upper housing 1. The radially magnetized magnetic ring 6 and the lower conductor 10 are all fixed to the inner surface of the lower housing 2 by the locking pins 11 of the lower housing 2.

[0037] Please see Figure 2 middle Figure 9 As shown, the assembly device provided by another aspect of the present invention mainly includes a base 12, a guide rail 15, a slide 16 and a limiting rod 18.

[0038] The base 12 has a rectangular structure. Arc-shaped grooves 13 and guide rail grooves 27 are respectively opened on both sides of its upper surface. Specifically, the upper and lower reaches are divided based on the length direction of the base 12, and the arc-shaped grooves 13 and guide rail grooves 27 are distributed in an upper and lower range.

[0039] The guide rail 15 has a rectangular parallelepiped structure and is fixedly installed in the guide rail groove 27. The width of the guide rail 15 is smaller than the width of the guide rail groove 27.

[0040] One slide block 16 is provided for each of the upper housing 1, lower housing 2, upper support ring 3, lower support ring 4, and diaphragm 5 of the planar coil diaphragm loudspeaker, respectively, to support the upper housing 1, lower housing 2, upper support ring 3, lower support ring 4, and diaphragm 5. Five slide blocks 16 are arranged sequentially from upstream to downstream along the length of the guide rail 15. The downstreammost slide block 16 is fixed in position along the length of the guide rail 15. The remaining four slide blocks 16 are slidably mounted on the guide rail 15, and each of the five slide blocks 16 has a limiting groove 17 on its top.

[0041] Specifically, the upper housing 1, lower housing 2, upper support ring 3, lower support ring 4, and diaphragm 5 are all inserted into the limiting grooves 17 on the corresponding slides 16 to maintain an upright state. During the assembly of the planar coil diaphragm loudspeaker, the upper housing 1, lower housing 2, upper support ring 3, lower support ring 4, and diaphragm 5 are brought closer together by the displacement of all four slides 16 towards the downstream slide 16.

[0042] The slide 16 includes a central support plate 16.1 and a limiting plate 16.2 that is vertically movable on the central support plate 16.1 in a direction perpendicular to the upper surface of the base 12. A limiting groove 17 is formed at the top of the limiting plate 16.2, and the top of the central support plate 16.1 is inserted into the limiting groove 17 to form the bottom portion of the limiting groove 17. At this time, the limiting groove 17 is configured to penetrate the top portion of the limiting plate 16.2 in the height direction, and the top of the central support plate 16.1 is inserted into the limiting groove 17 from the bottom opening to form the bottom of the limiting groove 17. When the upper housing 1 / lower housing 2 / upper support ring 3 / lower support ring 4 / diaphragm 5 are vertically inserted into the limiting groove 17, their bottoms are supported by the corresponding tops of the central support plate 16.1. The top of the central support plate 16.1 is configured with an arc-shaped structure.

[0043] Furthermore, the slide block 16, which slides in conjunction with the guide rail 15, moves towards the downstream slide block 16, causing adjacent slide blocks 16 to engage during the contact process. Simultaneously, the limiting plate 16.2 moves downwards, exposing the top of the central support plate 16.1 from the limiting groove 17. At this time, when the five slide blocks 16 sequentially contact and engage, the limiting plates 16.2 in all five slide blocks 16 move downwards until their top height is less than or equal to the top height of the central support plate 16.1, allowing the bottoms of the upper housing 1, lower housing 2, upper support ring 3, lower support ring 4, and diaphragm 5 to disengage from the limiting groove 17. In this embodiment, the top shape of the limiting plate 16.2 is set to an arc-shaped structure that matches the top shape of the central support plate 16.1.

[0044] One limiting rod 18 is provided on each side of the base 12. When the upper shell 1, lower shell 2, upper support ring 3, lower support ring 4, and diaphragm 5 are all placed in the limiting groove 17, the two sides contact the limiting rod 18. The inner surface of the limiting rod 18 is an arc surface. Specifically, the limiting rod 18, together with the limiting groove 17, improves the stability of supporting the upper shell 1, lower shell 2, upper support ring 3, lower support ring 4, and diaphragm 5. Especially after the bottom of the upper shell 1, lower shell 2, upper support ring 3, lower support ring 4, and diaphragm 5 is disengaged from the limiting groove 17, the two limiting rods 18 can prevent the upper shell 1, lower shell 2, upper support ring 3, lower support ring 4, and diaphragm 5 from tipping over. In this embodiment, when the limiting rod 18 supports the upper housing 1, lower housing 2, upper support ring 3, lower support ring 4 and diaphragm 5 from both sides, the limiting rod 18 is located below the horizontal diameter line of the upper housing 1, lower housing 2, upper support ring 3, lower support ring 4 and diaphragm 5 and is positioned as close as possible to both ends of the horizontal diameter line.

[0045] When the assembly device described above is applied to the assembly of a planar coil diaphragm loudspeaker, the lower housing 2, lower support ring 4, diaphragm 5, upper support ring 3 and upper housing 1 of the planar coil diaphragm loudspeaker are first inserted into the limiting grooves 17 in the five slides 16 in a distribution order from upstream to downstream. At this time, the upper housing 1 and the upper support ring 3 are at their maximum distance, and the lower housing 2 and the lower support ring 4 are at their maximum distance.

[0046] Then, the vertical outer magnetic ring 7, the vertical inner magnetic ring 8 and the upper conductor 9 are sequentially inserted between the locking pins 11 on the inner surface of the upper housing 1 and fixed to the inner surface of the upper housing 1. The radial magnetized magnetic ring 6 and the lower conductor 10 are sequentially inserted between the locking pins 11 on the inner surface of the lower housing 2 and fixed to the lower housing 2.

[0047] Then push the uppermost slide block 16—that is, the slide block 16 with the lower housing 2 inserted into the limiting groove 17—so that the four slide blocks 16 that slide with the guide rail 15 support the lower housing 2, the lower support ring 4, the diaphragm 5 and the upper support ring 3 respectively toward the lowermost slide block 16.

[0048] During the process of the five slide blocks 16 contacting and fitting together in sequence, the limiting plates 16.2 on each slide block 16 are all displaced downward on the central support plate 16.1, so that the bottom of the upper shell 1, lower shell 2, upper support ring 3, lower support ring 4 and diaphragm 5 are separated from the limiting groove 17 and exposed in a state supported by the top of the central support plate 16.1.

[0049] At this time, the tops of the five slides 16 are located on the same arc surface, and the lower housing 2 can be pushed directly downstream, so that the lower housing 2, the lower support ring 4, the diaphragm 5, and the upper support ring 3 are displaced to the side of the upper housing 1 and are pressed together in sequence. Then, the screws are installed on the upper housing 1, passing through the upper support ring 3, the diaphragm 5 and the lower support ring 4 in sequence, and then connected to the lower housing 2, so as to realize the assembly of the planar coil diaphragm speaker.

[0050] After applying the assembly device of the present invention, compared with the prior art method of manually stacking and assembling the various parts of the planar coil diaphragm loudspeaker, the efficiency is higher and the operation is also very convenient.

[0051] The guide rail 15 has a push plate 19 at its upstream end and a baffle 20 at its downstream end. The push plate 19 contacts the upstream end face of the lower housing 2, and the baffle 20 contacts the downstream end face of the upper housing 1. The baffle 20 has a diameter smaller than the diameter of the end face of the upper housing 1, so that the screw holes on the upper housing 1 are located outside the baffle 20. At this time, the baffle 20 is used to support the downstream end face of the upper housing 1. When the upper housing 1, the upper support ring 3, the diaphragm 5, and the lower housing 2 move to the side of the upper housing 1 and finally come into a state of sequential close contact, the baffle 20 supports the upper housing 1. The baffle 20 is used to push the push plate 19 when the lower housing 2, the lower support ring 4, the diaphragm 5, the upper support ring 3, and the bottom of the upper housing 1 are separated from the corresponding limiting groove 17 and when the lower housing 2, the lower support ring 4, the diaphragm 5, and the upper support ring 3 are pushed to the side of the upper housing 1 and come into a state of sequential close contact.

[0052] Furthermore, the push plate 19 includes a first circular portion 19.1 that contacts the upstream end face of the lower housing 2 and a second circular portion 19.2 disposed on the upstream end face of the first circular portion 19.1. The size of the first circular portion 19.1 is smaller than that of the second circular portion 19.2. The circumferential surface of the first circular portion 19.1 contacts the top of the limiting plate 16.2 below it, and the circumferential surface of the second circular portion 19.2 is flush with the circumferential surface of the lower housing 2.

[0053] After the above settings are made, during the process of pushing the slide block 16 to move using the push plate 19, the second circular part 19.2 directly contacts the limiting plate 16.2 of the uppermost slide block 16, which can prevent the first circular part 19.1 from applying force to the lower housing 2, causing the lower housing 2 to detach from or deform from the limiting groove 17.

[0054] The upstream end face of the uppermost limiting plate 16.2 is provided with an "L"-shaped stop 21, and the bottom of the second circular portion 19.2 is inserted into the stop 21. Specifically, in the initial state, the bottom of the second circular portion 19.2 is located between the vertical part of the stop 21 and the limiting plate 16.2 of the uppermost slide 16. When the limiting plates 16.2 on all slides 16 are displaced downwards, so that the lower housing 2, lower support ring 4, diaphragm 5, upper support ring 3 and upper housing 1 are supported by the corresponding middle support plate 16.1 and separated from the limiting groove 17, the bottom height of the circumferential surface of the second circular portion 19.2 is greater than or equal to the top height of the uppermost limiting plate 16.2 and the middle support plate 16.1, so that the push plate 19 can be pushed directly downstream. The push plate 19 will push the lower housing 2, lower support ring 4, diaphragm 5 and upper support ring 3 to the side of the upper housing 1 and stick to it in sequence. During the return process of the push plate 19, it will contact the stop block 21, which will allow the upstream slide block 16 to return to its initial position.

[0055] In the assembly device of this invention, the limiting plate 16.2 is fitted onto the middle support plate 16.1 from the top. Longitudinal sliders 16.1a are provided on both sides of the middle support plate 16.1. Longitudinal grooves 16.2a are provided on the inner walls of both sides of the limiting plate 16.2. The longitudinal sliders 16.1a are slidably disposed within the longitudinal grooves 16.2a, and a support spring 16.3 is provided between the top of the longitudinal slider 16.1a and the inner top wall of the longitudinal groove 16.2a. At this time, the support spring 16.3 can use its elasticity to maintain the top height of the limiting plate 16.2 being greater than the top height of the middle support plate 16.1 in the initial state, and allows the limiting plate 16.2 to move upwards on the middle support plate 16.1 to return to its initial state during the subsequent recovery process. The longitudinal sliders 16.1a, through their cooperation with the longitudinal grooves 16.2a, achieve a sliding fit between the middle support plate 16.1 and the limiting plate 16.2. Specifically, the limiting plate 16.2 has an inverted "U" shape in its thickness direction, with the middle support plate 16.1 inside it. The limiting groove 17 is opened in the middle part of the top of the limiting plate 16.2 and is in a through state, so that the top of the middle support plate 16.1 inside it can be inserted into the limiting groove 17.

[0056] Furthermore, both the bottom of the central support plate 16.1 and the limiting plate 16.2 are provided with guide rail grooves 27 that fit onto the guide rail 15. The inner walls of the guide rail grooves 27 of the central support plate 16.1, which slides with the guide rail 15, are provided with transverse sliders 16.1b. Both sides of the guide rail 15 are provided with transverse sliding grooves 15.1, and the transverse sliders 16.1b are slidably disposed within their corresponding transverse sliding grooves 15.1. The downstream central support plate 16.1 is fixedly disposed on the guide rail 15. Specifically, both the central support plate 16.1 and the limiting plate 16.2 have a "U"-shaped structure in their width direction, and the central support plate 16.1 of the four sliding blocks 16 that slide with the guide rail 15 achieves sliding engagement with the guide rail 15 through the cooperation of the transverse sliders 16.1b and the transverse sliding grooves 15.1. At this time, the middle support plate 16.1 supports the limiting plate 16.2 to move along the length direction on the guide rail 15 by utilizing the sliding cooperation between the transverse slider 16.1b and the transverse slide groove 15.1.

[0057] Furthermore, the five slide blocks 16 are equidistant when the distance between two adjacent slide blocks 16 is at its maximum, and the upstream ends of the four transverse sliders 16.1b respectively contact the inner wall of the upstream end of their corresponding transverse grooves 15.1.

[0058] Specifically, the transverse grooves 15.1 corresponding to the four slide blocks 16 are distributed sequentially along the height direction on the side of the guide rail 15, and are staggered from each other in the height direction. The initial state is when the distance between any two adjacent slide blocks 16 is at its maximum. In this state, the upstream end of the transverse slider 16.1b contacts the inner wall of the upstream end of its corresponding transverse groove 15.1, which facilitates the restoration of the slide block 16 to its initial position.

[0059] A synchronizing rod assembly 28 is provided between the sides of the limiting plates 16.2 of two adjacent slide blocks 16. The synchronizing rod assembly 28 includes a first rod 28.1 and a second rod 28.2. The opposite ends of the first rod 28.1 and the second rod 28.2 are rotatably engaged. The opposite ends of the first rod 28.1 and the second rod 28.2 are respectively rotatably connected to the sides of the two adjacent limiting plates 16.2. The opposite ends of the first rod 28.1 and the second rod 28.2 are both provided with teeth 28.3. The teeth 28.3 on the first rod 28.1 and the second rod 28.2 on the same side of the limiting plate 16.2 are in an interlocking state.

[0060] Specifically, the synchronizing rod assembly 28 connects two adjacent slide blocks 16 by connecting two adjacent limiting plates 16.2. Simultaneously, during the displacement of the uppermost slide block 16 on the guide rail 15 under the force of the push plate 19, the two first rods 28.1 and second rods 28.2 in the synchronizing rod assembly 28 are engaged by teeth 28.3. When any one of the first rods 28.1 or second rods 28.2 in the synchronizing rod assembly 28 rotates, all synchronizing rod assemblies 28 will move synchronously. This better ensures the consistency of movement of the four slide blocks 16 that slide with the guide rail 15, and allows adjacent slide blocks 16 to be synchronously and tightly pressed together.

[0061] In addition, when the distance between two adjacent slide blocks 16 is at its maximum, the opposite ends of the first rod 28.1 and the second rod 28.2 between the two adjacent slide blocks 16 are inclined downwards. At this time, it is easier to drive the synchronizing rod assembly 28 to rotate downwards when the uppermost slide block 16 is subjected to force.

[0062] Furthermore, on both sides of the two middle support plates 16.1 located at the upstream and downstream ends, a first abutment plate 29 located outside the limiting plate 16.2 is fixedly provided. A second abutment plate 30 is fixedly provided at the end of the first rod 28.1 rotatably connected to the outer side of the upstream limiting plate 16.2 and at the end of the second rod 28.2 rotatably connected to the outer side of the downstream limiting plate 16.2. The first abutment plate 29 and the second abutment plate 30 are configured such that, during the close contact of two adjacent slide blocks 16, the synchronous rod assembly 28... During the rotation, the first rod 28.1 at the uppermost position drives the second abutment plate 30 on it to abut against the bottom of the first abutment plate 29. At the same time, the second rod 28.2 at the lowermost position drives the second abutment plate 30 on it to abut against the bottom of the first abutment plate 29. This causes the uppermost and lowermost limiting plates 16.2 to move downward on the middle support plate 16.1. During this process, under the action of the synchronizing rod assembly 28, the limiting plates 16.2 on the other slides 16 move downward synchronously.

[0063] The following further describes the usage process of the assembly device of the present invention:

[0064] First, in the initial state, the two adjacent slide blocks 16 are at their maximum distance. At this time, the upstream end of the transverse slider 16.1b contacts the inner wall of the upstream end of its corresponding transverse slide groove 15.1; the limiting plate 16.2 is in the highest position under the action of the support spring 16.3, and the middle support plate 16.1 forms the bottom of its corresponding limiting groove 17.

[0065] Step 1: Insert the lower housing 2, lower support ring 4, diaphragm 5, upper support ring 3 and upper housing 1 into the corresponding limiting grooves 17 in sequence from upstream to downstream. At this time, the lower housing 2, lower support ring 4, diaphragm 5, upper support ring 3 and upper housing 1 are all stably supported in an upright state.

[0066] Step 2: Insert the vertical outer magnetic ring 7, the vertical inner magnetic ring 8, and the upper conductor 9 into the slots 11 on the inner surface of the upper housing 1 in sequence and fix them to the inner surface of the upper housing 1. Insert the radial magnetized magnetic ring 6 and the lower conductor 10 into the slots 11 on the inner surface of the lower housing 2 in sequence and fix them to the lower housing 2.

[0067] Step 3: Push the push plate 19 downstream. Under the action of the synchronizing rod assembly 28, the four slide blocks 16 that are slidably engaged with the guide rail 15 simultaneously move downstream and move closer to the downstream slide block 16.

[0068] Step 4: During the contact process between two adjacent slide blocks 16, the second abutting plate 30 abuts against the bottom of the first abutting plate 29, causing the limiting plates 16.2 in the two upstream and downstream slide blocks 16 to move downward on the corresponding middle support plate 16.1 and compress the support spring 16.3. Under the action of the synchronizing rod assembly 28, the limiting plates 16.2 in the remaining slide blocks 16 also move downward synchronously. At this time, the lower housing 2, lower support ring 4, diaphragm 5, upper support ring 3, and upper housing 1 are all exposed and supported by the limiting rod 18. Furthermore, the bottom of the second circular portion 19.2 of the push plate 19 is located above the slide block 16 in the height direction.

[0069] Step 5: Continue to push the push plate 19 downstream. As the push plate 19 pushes the lower housing 2 downstream, it also pushes the lower support ring 4, diaphragm 5 and upper support ring 3 to move, and finally the lower housing 2, lower support ring 4, diaphragm 5, upper support ring 3 and upper housing 1 are in a state of close contact.

[0070] Step 6: Install the screws onto the upper housing 1 to fix the various parts of the planar coil diaphragm speaker.

[0071] Step 7: Pull the push plate 19 back. The push plate 19 causes the uppermost slide 16 to move upstream and return to its original position via the stop block 21. During this process, the synchronizing rod assembly 28 returns to its original position, and the limiting plates 16.2 in all slides 16 move upward and return to their initial positions.

[0072] A support ring 22 is fixedly installed at the downstream end of the arc-shaped groove 13. A connecting ring 23 is rotatably installed on the inner ring of the support ring 22. The upstream end of the limiting rod 18 is fixedly installed on the connecting ring 23. A sliding rod 24 is inserted into the upstream end of the limiting rod 18. An operating plate 25 is fixedly installed at the upstream end of the sliding rod 24. A push rod 26 is fixedly installed between the operating plate 25 and the push plate 19. By pushing the operating plate 25, the operating plate 25, in conjunction with the push rod 26, can drive the push plate 19 to move. The operating plate 25 is always located outside the range of the guide rail 15, making operation more convenient.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
