With the improvement of electronic product performance and miniaturization, improvements in the acoustic performance and spatial arrangement of sound-generating devices are inevitable trends.

[0003] A loudspeaker typically consists of a magnetic circuit system and a resonant system. When the voice coil of the resonant system is energized, it generates an induced magnetic field. This induced magnetic field interacts with the magnetic field of the magnetic circuit system to produce an upward or downward force, causing the diaphragm of the resonant system to vibrate and push air to produce sound. Additionally, depending on the application environment, loudspeakers may also incorporate inductors to enhance their acoustic performance.

[0004] In related technologies, the inductor structure of loudspeakers is usually fixed by adhesive. The firmness of the fixation depends on the weather resistance of the adhesive. Furthermore, the inductor structure is exposed on the outside of the loudspeaker, and auxiliary terminals need to be led out separately to solder the inductor, which has a significant impact on space utilization and cost.

[0028] In recent years, with the rapid development of consumer electronics, these products have gained widespread application and consumer acceptance. Sound-generating devices are crucial electroacoustic transducers in consumer electronics, widely used as speakers, earpieces, and headphones. With the improvement of electronic product performance and miniaturization, improvements in the acoustic performance and spatial arrangement of sound-generating devices are inevitable trends.

[0029] A loudspeaker typically consists of a magnetic circuit system and a resonant system. When the voice coil of the resonant system is energized, it generates an induced magnetic field. This induced magnetic field interacts with the magnetic field of the magnetic circuit system to produce an upward or downward force, causing the diaphragm of the resonant system to vibrate and push air to produce sound. Additionally, depending on the application environment, loudspeakers may also incorporate inductors to enhance their acoustic performance, particularly low-frequency performance.

[0030] In related technologies, the inductor structure of a loudspeaker is usually arranged on the side of the loudspeaker's exterior, exposing the inductor structure on the outside of the loudspeaker. It is then fixed with adhesive. The strength of the fixation depends on the weather resistance of the adhesive. Moreover, the inductor structure is generally cylindrical, with a small bonding area, resulting in poor connection stability. In addition, it is necessary to separately lead out auxiliary terminals to weld the inductor structure to ensure that the inductor structure is connected in series with the voice coil of the vibration system. This makes the structure of the auxiliary terminals complex, which has a significant impact on space utilization and cost.

[0031] This invention proposes a sound-generating device 100. It is understood that the sound-generating device 100 is applied to electronic devices, which may include televisions, speakers, smart wearable devices, vehicles, etc., and are not limited thereto.

[0032] Please refer to the reference. Figures 1 to 15 As shown, in this embodiment of the invention, the sound-generating device 100 includes a frame 1, a vibration system 2, a terminal assembly 3, and an inductor assembly 4. The frame 1 is provided with an installation space 121. The vibration system 2 vibrates along a first direction. The vibration system 2 includes a diaphragm 21 and a voice coil 22 connected to the diaphragm 21. The outer periphery of the diaphragm 21 is connected to one end of the frame 1. The terminal assembly 3 is disposed on the frame 1. One end of the terminal assembly 3 is connected to the lead wire of the voice coil 22, and the other end of the terminal assembly 3 is used to connect to an external circuit. The inductor assembly 4 is disposed in the installation space 121. The inductor assembly 4 is connected in series with the voice coil 22 through the terminal assembly 3. The axial direction of the inductor assembly 4 is parallel to the first direction.

[0033] In this embodiment, the sound-generating device 100 can be a miniature loudspeaker or a loudspeaker unit. For example... Figures 1 to 3 , Figure 5 and Figure 10 As shown, the sound-generating device 100 also includes a magnetic circuit system 5. The magnetic circuit system 5 is connected to the end of the frame 1 away from the diaphragm 21, and is opposite to and spaced from the diaphragm 21. The magnetic circuit system 5 is provided with a magnetic gap 53, and the end of the voice coil 22 away from the diaphragm 21 is suspended in the magnetic gap 53. It can be understood that the sound-generating device 100 includes a frame 1 and a vibration system 2 and a magnetic circuit system 5 housed in the frame 1. The vibration system 2 and the magnetic circuit system 5 of the sound-generating device 100 are arranged opposite to each other, that is, the diaphragm 21 of the vibration system 2 and the magnetic circuit system 5 are arranged opposite to and spaced from each other. The magnetic circuit system 5 is provided with a magnetic gap 53. One end of the voice coil 22 of the vibration system 2 is connected to the diaphragm 21, and the other end of the voice coil 22 is correspondingly arranged with respect to the magnetic gap 53.

[0034] Understandably, the side of the vibration system 2 of the sound-generating device 100 facing away from the magnetic circuit system 5 forms the sound radiation surface of the sound-generating device 100, and the side of the magnetic circuit system 5 facing away from the vibration system 2 forms the back side of the sound-generating device 100.

[0035] Optionally, the outer contour of the sound-generating device 100 can be circular or square, etc., and is not limited here. In this embodiment, the vibration system 2 and the magnetic circuit system 5 are mounted on the frame 1 to integrate the sound-generating device 100 into a single structure, and is not limited here.

[0036] In this embodiment, the frame 1 has a cavity 111. The diaphragm 21 of the vibration system 2 is connected to one end of the frame 1, and the magnetic circuit system 5 is connected to the other end of the frame 1, and is positioned opposite and spaced apart from the diaphragm 21. One end of the voice coil 22 is connected to the side of the diaphragm 21 facing the magnetic circuit system 5, and the other end of the voice coil 22 is correspondingly positioned with the magnetic gap 53 of the magnetic circuit system 5. When an electric current is passed through the voice coil 22, it vibrates in the magnetic field formed by the magnetic circuit system 5, thereby driving the diaphragm 21 to vibrate and produce sound. It should be noted that the voice coil 22 of the vibration system 2 drives the diaphragm 21 to vibrate along a first direction. That is, the vibration system 2 and the magnetic circuit system 5 are positioned opposite each other along the first direction.

[0037] In order to allow current to be supplied to the voice coil 22, in this embodiment, as follows: Figure 1 , Figure 3 , Figures 4 to 6 , Figures 8 to 10 , Figure 12 and Figure 13 As shown, the sound-generating device 100 also includes a terminal assembly 3, which is disposed on the frame 1. One end of the terminal assembly 3 is connected to the lead wire of the voice coil 22, and the other end of the terminal assembly 3 is used to connect to an external circuit, thus realizing the connection and conduction between the voice coil 22 and the external circuit.

[0038] To improve the acoustic performance of the sound-generating device 100, especially its low-frequency performance, in one embodiment, such as Figures 1 to 9 , Figures 12 to 15 As shown, the sound-generating device 100 also includes an inductor assembly 4, which is disposed on the frame 1 and connected in series with the voice coil 22.

[0039] In this embodiment, as Figures 2 to 4 , Figures 6 to 8 , Figure 10 , Figure 11 As shown, the basin frame 1 has an installation space 121, which is optionally located on the outside of the basin frame 1. The inductor assembly 4 is disposed within the installation space 121, and the axial direction of the inductor assembly 4 is parallel to the first direction. It can be understood that this arrangement allows the axial direction of the inductor assembly 4 to be consistent with the vibration direction of the vibration system 2, thereby reducing the space occupied by the inductor assembly 4 on the outside of the basin frame 1. At the same time, the installation space 121 is used to install and fix the inductor assembly 4, effectively increasing the connection area and improving the connection stability.

[0040] Optionally, the inductor assembly 4 is connected in series with the voice coil 22 via the terminal assembly 3. This arrangement effectively simplifies the structural design of the terminal assembly 3 and saves costs.

[0041] The sound-generating device 100 of the present invention utilizes a frame 1 to house and install a vibration system 2, thereby achieving the installation, fixation, support, and protection of the vibration system 2. Simultaneously, a terminal assembly 3 is placed on the frame 1, facilitating the connection and conduction of the voice coil 22 of the vibration system 2 with the inductor assembly 4 and external circuitry via the terminal assembly 3. Furthermore, an installation space 121 is provided on the frame 1, making the axial direction of the inductor assembly 4 parallel to the vibration direction of the vibration system 2, i.e., the first direction. This allows for both the fixation and installation limitation of the inductor assembly 4 using the installation space 121, improving the connection stability of the inductor assembly 4, and saving product layout space, thus increasing the utilization rate of the occupied space.

[0042] In one embodiment, the basin frame 1 includes a main body 11 and a connector 12 connected to the outside of the main body 11. The periphery of the diaphragm 21 is connected to one end of the main body 11. The connector 12 is provided with an installation space 121 and a connector space 122 adjacent to the installation space 121. One end of the terminal assembly 3 is located in the connector space 122 and is used to connect to an external circuit.

[0043] In this embodiment, as Figures 1 to 11 As shown, by setting the basin frame 1 as the main body 11 and the connector 12, the vibration system 2 and the magnetic circuit system 5 are connected and fixed by the main body 11, and the connector 12 is set on the outside of the main body 11. The terminal assembly 3 and the inductor assembly 4 are installed and fixed by the connector 12, thus avoiding interference or other effects of the terminal assembly 3 and the inductor assembly 4 on the vibration system 2 and the magnetic circuit system 5.

[0044] Understandably, the connector 12 is provided with an adjacent mounting space 121 and a plugging space 122. The mounting space 121 is used to mount and fix the inductor assembly 4, and one end of the terminal assembly 3 is located in the plugging space 122 for connection with an external circuit. In this way, the plugging space 122 can be used to provide connection space for the connector of the external circuit and protect the terminal assembly 3.

[0045] Optionally, the main body 11 and the connector 12 of the basin frame 1 are integrally injection molded. This arrangement can improve the structural strength of the basin frame 1 and simplify the manufacturing process. In this embodiment, the terminal assembly 3 is optionally integrally injection molded onto the connector 12. This can not only achieve the connection and fixation between the terminal assembly 3 and the basin frame 1, but also improve the connection stability, simplify the assembly steps, and improve assembly efficiency.

[0046] In one implementation, such as Figures 2 to 4 , Figure 6 , Figure 10As shown, the basin frame 1 also includes reinforcing ribs 13, one end of which is connected to the connector 12, and the other end of which is connected to the main body 11. It is understood that by providing reinforcing ribs 13, the connection stability between the connector 12 and the main body 11 can be further improved, ensuring that the connection between the connector 12 and the main body 11 is prevented from breaking when connected to external circuits, thus extending service life. Optionally, multiple reinforcing ribs 13 are provided at intervals.

[0047] In this embodiment, as Figures 1 to 5 , Figure 10 As shown, the main body 11 has a cavity 111 and a through hole 112 communicating with the cavity 111. The lead wire of the voice coil 22 passes through the through hole 112 and connects to the terminal assembly 3. It can be understood that the cavity 111 is used to house and assemble the vibration system 2 and the magnetic circuit system 5. The through hole 112 can achieve air pressure balance on both sides of the diaphragm 21 and facilitates the lead wire of the voice coil 22 to pass through the through hole 112 and connect to the terminal assembly 3, thereby improving assembly efficiency.

[0048] Understandably, the outer periphery of the diaphragm 21 of the vibration system 2 is connected to the first end of the main body 11, and the magnetic circuit system 5 is connected to the second end of the main body 11, so that the diaphragm 21, the cavity 111 of the frame 1, and the magnetic circuit system 5 cooperate to form a rear cavity. By setting a through hole 112, the through hole 112 connects the rear cavity to the outside. On the one hand, the through hole 112 can be used to release air, and on the other hand, the volume of the rear cavity of the sound generating device 100 can be expanded, thereby improving the acoustic performance and low-frequency extension capability of the sound generating device 100.

[0049] Optionally, the insertion space 122 extends along the first direction and has a third opening 126 located on the side of the connector 12 facing away from the diaphragm 21. It is understood that this arrangement, after the sound-generating device 100 is installed in the electronic device, facilitates the assembly of the connector plug between the sound-generating device 100 and the electronic device. That is, the connector plug of the electronic device can be inserted into the insertion space 122 through the third opening 126 and connected to the terminal assembly 3. This not only protects the connector plug of the electronic device but also guides and positions it during assembly, improving insertion efficiency.

[0050] In one embodiment, the inductor assembly 4 is disposed within the mounting space 121 and snap-fitted into the connector 12. In this embodiment, as... Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 9 As shown, by installing the inductor assembly 4 in the installation space 121 and connecting it with the connector 12, the inductor assembly 4 can be limited and fixed, and the inductor assembly 4 can be positioned.

[0051] Understandably, one of the inductor assembly 4 and the connector 12 is provided with a snap-fit ​​component, and the other is provided with a snap-fit ​​component. Thus, when the inductor assembly 4 is located in the installation space 121, the snap-fit ​​component and the snap-fit ​​component are snapped together to fix the inductor assembly 4 in the installation space 121 of the connector 12.

[0052] In one embodiment, the inductor assembly 4 includes a mounting sleeve 41 and an inductor element 42. The mounting sleeve 41 has a receiving cavity 411 extending in a first direction. One end of the receiving cavity 411 has a first opening 414. The inductor element 42 is disposed in the receiving cavity 411. The inductor assembly 4 is disposed in the mounting space 121, and a portion of the terminal assembly 3 passes through the first opening 414 and is connected to the inductor element 42.

[0053] In this embodiment, as Figure 3 , Figure 5 , Figure 7 , Figure 8 , Figures 12 to 15 As shown, by configuring the inductor assembly 4 as a mounting sleeve 41 and an inductor element 42, and providing a receiving cavity 411 in the mounting sleeve 41 such that one end of the receiving cavity 411 has a first opening 414 and the other end is closed, it is convenient for the inductor element 42 to be installed in the receiving cavity 411 from the first opening 414 of the mounting sleeve 41. This can improve the installation stability of the inductor element 42 and protect the inductor element 42 from being exposed to the outside.

[0054] Understandably, the mounting sleeve 41 can be a cylindrical structure. The mounting sleeve 41 extends along the first direction, that is, the receiving cavity 411 extends along the first direction, so that the inductor 42 is installed in the receiving cavity 411, and the axial direction of the inductor 42 is parallel to the first direction.

[0055] In this embodiment, the inductor assembly 4 is disposed in the installation space 121. The inductor assembly 4 is connected to the connector 12 by the installation sleeve 41. In this way, the inductor assembly 4 is installed and fixed by means of a mechanical structure, avoiding the use of adhesive to connect the inductor assembly 4 to the frame 1, while protecting and fixing the inductor element 42.

[0056] Understandably, the inductor assembly 4 is located within the installation space 121, and a portion of the terminal assembly 3 passes through the first opening 414 and connects to the inductor element 42, thereby enabling the inductor element 42 to be connected in series with the voice coil 22 through the terminal assembly 3 and to be connected and conductive with the external circuit.

[0057] In one embodiment, the mounting space 121 extends through the connector 12 in a first direction and has a second opening 123 on the side of the connector 12 facing the diaphragm 21; the mounting sleeve 41 has a latching protrusion 415 near the first opening 414, the connector 12 has a latching groove 124 near the second opening 123, the inductor assembly 4 is disposed in the mounting space 121, and the latching protrusion 415 is latched in the latching groove 124, and a portion of the terminal assembly 3 is exposed in the second opening 123 and passes through the first opening 414 to connect with the inductor element 42.

[0058] In this embodiment, as Figures 1 to 11 As shown, by setting the mounting space 121 as a through cavity structure that passes through the plug-in 12 in the first direction, the mounting space 121 has a second opening 123 on the side of the plug-in 12 facing the diaphragm 21 and a mounting port on the side of the plug-in 12 facing away from the diaphragm 21. This allows the inductor assembly 4 to be conveniently installed in the mounting space 121 through the mounting port, and the first opening 414 of the mounting sleeve 41 is located at the second opening 123, thereby facilitating the connection between the terminal assembly 3 and the inductor element 42 through the first opening 414 and exposed at the second opening 123, thus facilitating the connection between the terminal assembly 3 and the inductor element 42.

[0059] Understandable, such as Figures 5 to 7 , Figure 9 , Figures 11 to 15 As shown, by providing a latching protrusion 415 near the first opening 414 on the mounting sleeve 41 of the inductor assembly 4, and a latching groove 124 near the second opening 123 on the connector 12, the inductor assembly 4 is disposed in the mounting space 121, so that the latching protrusion 415 engages with the latching groove 124, thereby fixing the inductor assembly 4 in the mounting space 121 of the connector 12. The first opening 414 of the mounting sleeve 41 is located at the second opening 123, which facilitates the connection of the terminal assembly 3 to the inductor element 42 of the inductor assembly 4 at the second opening 123. The terminal assembly 3 fixes the inductor element 42 in the mounting sleeve 41 and further fixes the inductor assembly 4 at the second opening 123. Thus, through the latching engagement of the latching protrusion 415 and the latching groove 124, and the fixation of the inductor assembly 4 by the terminal assembly 3 at the second opening 123, the inductor assembly 4 is stably assembled in the first direction, improving the connection stability.

[0060] Optionally, the terminal assembly 3 is soldered to the inductor element 42 of the inductor assembly 4 at the second opening 123. Understandably, this further enhances the installation stability of the inductor assembly 4 by utilizing the terminal assembly 3, specifically through the double locking of the snap-fit ​​and soldering, improving the connection strength of the inductor assembly 4 and effectively simplifying the structure of the terminal assembly 3. It allows for the series connection of the inductor element 42 of the inductor assembly 4 with the voice coil 22, and also enables connection to external circuits, improving connection smoothness.

[0061] In one embodiment, the outer surface of the protrusion 415 is provided with a guide slope 416, and the inner wall of the mounting space 121 adjacent to the second opening 123 is provided with a mating slope 125.

[0062] In this embodiment, as Figure 7 , Figure 11 , Figure 14 and Figure 15 As shown, by providing a guide slope 416 on the protrusion 415 and a mating slope 125 on the inner wall of the mounting space 121 near the second opening 123, after the inductor assembly 4 is installed in the mounting space 121 through the mounting port of the mounting space 121, the guide slope 416 of the protrusion 415 slides along the mating slope 125 of the mounting space 121 near the second opening 123 and passes through the second opening 123, so that the protrusion 415 is engaged in the slot 124, thereby realizing the limiting and fixing of the inductor assembly 4.

[0063] Understandably, this setup allows for both guided installation and positioning assembly, improving assembly convenience and efficiency while preventing damage to the 415 protrusion during assembly.

[0064] Optionally, the latching protrusions 415 include multiple protrusions, which are spaced apart at the ends of the mounting sleeve 41 adjacent to the first opening 414. Optionally, the latching grooves 124 include multiple grooves, which are spaced apart at the insertion member 12 adjacent to the second opening 123. In this embodiment, the multiple latching protrusions 415 correspond one-to-one with the multiple latching grooves 124.

[0065] To ensure that the latching protrusion 415 has a certain degree of elasticity and deformation capability, in this embodiment, the latching protrusion 415 protrudes from the end of the mounting sleeve 41 adjacent to the first opening 414.

[0066] In one embodiment, the voice coil 22 has a first lead 221 and a second lead 222; the terminal assembly 3 includes a first terminal 31, a second terminal 32 and a third terminal 33 disposed on the connector 12, the first lead 221 and the second lead 222 are respectively connected to one end of the first terminal 31 and the second terminal 32, the wire of the inductor 42 is connected to the other end of the second terminal 32, one end of the third terminal 33 is exposed in the second opening 123 and passes through the first opening 414 and is soldered to the other end of the inductor 42, the other ends of the first terminal 31 and the third terminal 33 are located in the plug-in space 122 for connection to an external circuit; wherein, the inductor 42 is connected in series with the voice coil 22 through the second terminal 32.

[0067] In this embodiment, as Figure 1 , Figure 3 , Figure 5 , Figure 8 , Figure 9 , Figure 12 and Figure 13 As shown, by setting the terminal assembly 3 as a first terminal 31, a second terminal 32 and a third terminal 33, the second terminal 32 is used to connect the voice coil 22 and the inductor element 42 of the inductor assembly 4 in series. The first terminal 31 and the third terminal 33 are respectively connected to the first lead 221 of the voice coil 22 and the inductor element 42, so that the other end of the first terminal 31 and the third terminal 33 is located in the insertion space 122 for connection with the external circuit, thereby realizing the connection and conduction between the external circuit and the inductor element 42 and the voice coil 22.

[0068] Understandably, by exposing one end of the third terminal 33 in the second opening 123 and welding it through the first opening 414 to the other end of the inductor 42, not only is the connection between the third terminal 33 and the inductor 42 made conductive, but the third terminal 33 is also used to fix the inductor assembly 4 at the second opening 123. With the inductor assembly 4 and the connector 12 engaging with the latch protrusion 415 and the slot 124 at the second opening 123, the inductor assembly 4 can be firmly fixed in the installation space 121 of the connector 12. This not only improves the installation stability of the inductor assembly 4, but also allows the connector 12 to accommodate and install the inductor assembly 4, saving product layout space, improving the utilization rate of the space occupied, and avoiding exposure to the outside of the basket 1. Moreover, the fixing of the inductor assembly 4 is entirely done by mechanical structure, effectively avoiding the influence of external environmental factors on the installation of the inductor assembly 4.

[0069] Optionally, the first terminal 31, the second terminal 32, and the third terminal 33 of the terminal assembly 3 are all embedded in the connector 12 of the basin frame 1. In this embodiment, as shown... Figure 1 , Figures 3 to 5 , Figure 8 , Figure 9As shown, the first terminal 31, the second terminal 32, and the third terminal 33 are integrally injection molded with the basin frame 1. This not only improves connection stability but also simplifies the assembly process.

[0070] In this embodiment, as Figure 12 and Figure 13 As shown, the first terminal 31 includes a first connecting end 311, a first connecting portion 313, and a second connecting end 312 connected in sequence. Both the first connecting end 311 and the second connecting end 312 extend along a first direction. The first connecting portion 313 is embedded within the connector 12. The end of the first connecting end 311 away from the first connecting portion 313 protrudes from the side surface of the connector 12 facing the diaphragm 21 and is connected to the first lead 221. The second connecting end 312 is located within the insertion space 122. The second terminal 32 includes a third connecting end 321 and a fourth connecting end 322 connected in sequence. All 322 extend along the first direction. The end of the third connection 321 away from the fourth connection 322 protrudes from the side surface of the plug-in 12 facing the diaphragm 21 and is connected to the second lead 222. The end of the fourth connection 322 away from the third connection 321 protrudes from the side surface of the plug-in 12 facing away from the diaphragm 21 and is connected to the wire of the inductor 42. The third terminal 33 includes a fifth connection 331 corresponding to the mounting space 121 and a sixth connection 332 located in the plug-in space 122. The fifth connection 331 is welded to the inductor 42, and the sixth connection 332 extends along the first direction.

[0071] Optionally, the third terminal 33 is located between the first terminal 31 and the second terminal 32.

[0072] In one embodiment, the mounting sleeve 41 includes a bottom wall 412 and a side wall 413 disposed around the bottom wall 412 and extending along a first direction. The side wall 413 and the bottom wall 412 enclose a receiving cavity 411. The mounting sleeve 41 is provided with a notch 417 communicating with the receiving cavity 411. The notch 417 penetrates the side wall 413 and the bottom wall 412 along the first direction.

[0073] In this embodiment, as Figure 4 , Figure 6 , Figure 8 , Figures 13 to 15 As shown, by providing a notch 417 on the mounting sleeve 41, the mounting sleeve 41 has a certain deformation capability. This not only facilitates the assembly of the inductor element 42 with the sleeve 41, but also allows for adjustment of inductor elements 42 of different sizes, models, or tolerances during the assembly process through the notch 417. Furthermore, the notch 417 provides clearance for the wires of the inductor element 42 during the assembly process, thus enabling smooth assembly.

[0074] Understandably, the notch 417 extends through the sidewall 413 and bottom wall 412 of the mounting sleeve 41 in the first direction. That is, the notch 417 includes a first segment 4171 formed in the sidewall 413 and a second segment 4172 formed in the bottom wall 412, and the first segment 4171 and the second segment 4172 are connected. Optionally, the width of the notch 417 is greater than or equal to the diameter of the wire of the inductor element 42.

[0075] In this embodiment, the width of the second segment 4172 may be greater than or equal to the width of the first segment 4171. This facilitates the adjustment of the wires of the inductor element 42 at the bottom wall 412 of the mounting sleeve 41, preventing damage to the wires of the inductor element 42. Optionally, the end of the second segment 4172 away from the first segment 4171 is circular or arc-shaped.

[0076] In one embodiment, the bottom wall 412 is provided with an extension 4173 connecting the second segment 4172, the extension 4173 extending toward the periphery of the bottom wall 412; wherein, the extension 4173 includes a plurality of extensions, the plurality of extensions 4173 are spaced apart and arranged radially along the center of the bottom wall 412; and / or, the size of the extension 4173 gradually decreases from the center of the bottom wall 412 to the periphery of the bottom wall 412.

[0077] In this embodiment, as Figure 4 , Figure 6 , Figure 8 , Figures 13 to 15 As shown, by providing an extension 4173 connecting the second segment 4172 to the bottom wall 412 of the mounting sleeve 41, the extension 4173 extends towards the periphery of the bottom wall 412. This serves two purposes: firstly, to increase the deformability of the notch 417, and secondly, to prevent the inductor 42 from falling out of the second segment 4172 of the notch 417. Optionally, the size of the extension 4173 gradually decreases from the center of the bottom wall 412 to the periphery of the bottom wall 412.

[0078] Optionally, the extension segment 4173 includes multiple segments, which are spaced apart and arranged radially along the center of the bottom wall 412. This arrangement can further increase the deformation capacity of the notch 417.

[0079] In this embodiment, as Figures 12 to 15 As shown, there are two locking protrusions 415. Optionally, the two locking protrusions 415 are symmetrically arranged on opposite sides of the line connecting the notch 417 and the axis of the mounting sleeve 41. This achieves both installation fixation and balanced installation of the inductor assembly 4.

Furthermore, the U-shaped iron 51 is connected to the second end of the main body 11 of the basin frame 1, thus achieving a fixed connection between the magnetic circuit system 5 and the basin frame 1.

[0082] To further improve connection stability, the basin frame 1 and the U-shaped iron 51 can optionally be integrally injection molded. In this embodiment, the U-shaped iron 51 and the main body 11 of the basin frame 1 are integrally injection molded. It is understood that the U-shaped iron 51 of the magnetic circuit system 5 is made of a magnet or a magnetically conductive material. The U-shaped iron 51 is placed in the mold, and then the injection molding material of the basin frame 1 is poured into the mold and integrally injection molded with the U-shaped iron 51; this is not limited here.

[0083] In this embodiment, as Figure 3 As shown, the central magnetic part 52 can be a central magnet and a central magnetic plate stacked together. The central magnet is connected to the bottom wall of the receiving groove 513, and the periphery of the central magnet and the central magnetic plate are spaced apart from the side wall of the receiving groove 513 to form a magnetic gap 53.

[0084] Of course, in other embodiments, the magnetic circuit system 5 can also be configured as a T-shaped iron and a side magnetic part. In this case, the T-shaped iron includes a base plate and a protruding post protruding from the center of the base plate. The side magnetic part is arranged around the protruding post and connected to the base plate, and the inner side of the side magnetic part is spaced from the outer peripheral wall of the protruding post to form a magnetic gap 53. It can be understood that the magnetic circuit system 5 is connected to the second end of the main body 11 of the basin frame 1 through the side magnetic part.

[0085] Optionally, the side magnetic part includes a side magnet and a side magnetic guide plate stacked together, with the side magnet sandwiched between the side magnetic guide plate and the base plate. In this embodiment, the side magnetic guide plate is integrally injection molded with the basin frame 1 and the support member 2, but this is not limited here.

[0086] In one embodiment, the U-shaped iron 51 includes a bottom 511 and a side portion 512 disposed around the bottom 511. The side portion 512 and the bottom 511 enclose each other to form a receiving groove 513. A central magnetic portion 52 is disposed on the bottom 511 and forms a magnetic gap 53 with the side portion 512. The side portion 512 and the second end are integrally injection molded.

[0087] In this embodiment, as Figure 3 As shown, the side portion 512 of the U-shaped iron 51 surrounds the periphery of the bottom 511, so that the side portion 512 and the bottom 511 enclose and form a receiving groove 513. Optionally, the side portion 512 and the bottom 511 are arranged perpendicularly.

[0088] Understandably, the side portion 512 of the U-shaped iron 51 is connected to the second end of the main body 11. Optionally, the end of the side portion 512 away from the bottom 511 is connected to the second end of the main body 11. In this embodiment, the side portion 512 and the second end of the main body 11 are optionally integrally injection molded.

[0089] In order to improve the connection stability between U-shaped iron 51 and basin stand 1, in one embodiment, a limiting protrusion is provided on the outer side of side 512, and a limiting groove is formed at the second end of main body 11 to cooperate with the limiting protrusion. The limiting protrusion is embedded in the limiting groove.

[0090] In this embodiment, a limiting protrusion is provided on the outer wall of the side portion 512 away from the bottom 511, and a limiting groove is formed at the second end of the tray 1, with the limiting protrusion embedded in the limiting groove. It can be understood that the limiting protrusion may be an annular protrusion extending around the outer periphery of the side portion 512; or, multiple limiting protrusions may be provided, spaced apart along the outer periphery of the side portion 512. Optionally, the limiting protrusions and limiting grooves may be provided in a one-to-one correspondence, which is not limited here.

[0091] In one embodiment, the bottom 511 protrudes towards the central magnet 52 to form a boss portion, the central magnet 52 is provided on the boss portion, and a clearance groove is formed between the boss portion and the side portion 512 to form a magnetic gap 53, the clearance groove being used to avoid the voice coil 22.

[0092] In this embodiment, by providing a boss at the bottom 511 of the U-shaped iron 51, the boss can be used to support the installation of the central magnet 52, and a clearance groove can be formed between the boss and the side 512 to form a magnetic gap 53. In this way, the clearance groove provides clearance for the voice coil 22 when it vibrates.

[0093] Understandably, the protrusion is formed by the side of the bottom 511 facing away from the central magnet 52 and protruding towards the diaphragm 21, so that the side of the bottom 511 facing away from the central magnet 52 is recessed, which is not limited here.

[0094] In one embodiment, the diaphragm 21 includes a spherical top, a cone portion surrounding the spherical top, a folded ring portion surrounding the cone portion, and a fixing portion located outside the folded ring portion. The fixing portion is connected to the first end of the main body 11, and the voice coil 22 is connected to the connection between the spherical top and the cone portion.

[0095] In this embodiment, as Figure 1 , Figure 3 and Figure 8 As shown, the dome, cone, surround, and fixing parts of the diaphragm 21 can be selected as an integrally molded structure, which can improve the strength of the diaphragm 21. It can be understood that the diaphragm 21 is connected to the dome through the cone, which on the one hand achieves sealing, and on the other hand adjusts the position of the voice coil 22 within the magnetic gap 53.

[0096] Optionally, the cone-shaped portion extends into the cavity 111, and from the top of the sphere to the folded ring portion, the cross-sectional dimension of the cone-shaped portion gradually increases along the vibration direction perpendicular to the vibration direction of the vibration system 2. In this embodiment, the outer contour of the diaphragm 21 is circular, and the cone-shaped portion is tapered.

[0097] Optionally, the top of the sphere protrudes towards the side away from the magnetic circuit system 5. This arrangement prevents the diaphragm 21 from interfering with the central magnetic part 52 of the magnetic circuit system 5 during vibration. In this embodiment, the folded ring protrudes towards the side away from the magnetic circuit system 5. This arrangement prevents the folded ring from interfering with the first end of the frame 1.

[0098] In one embodiment, a protrusion is provided at the connection between the top of the ball and the cone portion toward the voice coil 22, and the protrusion is connected to one end of the voice coil 22 near the diaphragm 21; wherein, there are multiple protrusions, and the multiple protrusions are arranged at intervals around the top of the ball.

[0099] In this embodiment, as Figure 3 As shown, by providing a protrusion at the connection between the spherical top and the cone portion of the diaphragm 21, the structural strength of the diaphragm 21 is further enhanced. Simultaneously, the protrusion connects to the end of the voice coil 22 near the diaphragm 21. This allows adjustment of the position of the voice coil 22 within the magnetic gap 53 and also creates a ventilation gap at the connection between the voice coil 22 and the spherical top and cone portion of the diaphragm 21, ensuring smooth airflow within the rear cavity. Optionally, multiple protrusions are provided, spaced apart around the spherical top.

[0100] To further ensure the balance of air pressure inside and outside the voice coil 22, in this embodiment, as follows: Figure 3 and Figure 12 As shown, the voice coil 22 extends along a first direction and has a through hole 223. Optionally, there are multiple through holes 223, which are spaced apart.

[0101] In one embodiment, the vibration system 2 further includes a centering support plate, the inner side of which is connected to the outer wall of the voice coil 22. A support platform is formed on the side of the main body 11 of the frame 1 facing the cavity 111. The support platform is located between the first end and the second end of the main body 11, and the outer side of the centering support plate is supported and connected to the support platform.

[0102] In this embodiment, as Figure 3 , Figure 8 , Figure 9 As shown, by setting a centering support, the voice coil 22 is centered, preventing polarization or oscillation during its vibration. Understandably, the centering support can be a spider structure. The centering support is annular, with its inner side connected to the outer wall of the voice coil 22 and its outer side connected to the frame 1.

[0103] Understandably, by forming a support platform on the side of the basin frame 1 facing the cavity 111, such that the support platform is located between the first end and the second end of the main body 11, the outer support of the centering support piece can be connected to the support platform, thereby improving the connection stability.

[0104] Optionally, from the first end to the second end of the main body 11, the cross-sectional area of ​​the basin frame 1 along the vibration direction perpendicular to the vibration system 2 gradually decreases. In this embodiment, the basin frame 1 has a basin-shaped or bowl-shaped structure. Both the first end and the second end of the basin frame 1 can be selected as a ring structure.

[0105] In this embodiment, as Figures 1 to 5 , Figure 8 and Figure 10 As shown, the basin frame 1 has multiple through holes 112, which are spaced apart and located between the first end and the second end, and the multiple through holes 112 connect to the cavity 111. This can increase the volume of the rear cavity. Optionally, the multiple through holes 112 can be located on both sides of the centering support, so as to balance the air pressure on both sides of the centering support.
