Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0049] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0050] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0051] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0053] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0054] See Figures 1-4 One embodiment of this application provides a speaker bracket 1, including a base frame 11 and a partition 12. The base frame 11 has an internal accommodating space 110. The partition 12 is disposed on the base frame 11 and divides the accommodating space 110 into two spaced-apart accommodating openings 111 along the length of the base frame 11. This allows the base frame 11 to accommodate two voice coils 21 through the two accommodating openings 111, thereby enabling the speaker device 2 mounted on the speaker bracket 1 of this application to have a dual voice coil design, allowing the speaker device 2 to achieve optimal bass performance within a limited space.

[0055] The receiving opening 111 has two opposing mounting surfaces 117 extending along the width direction of the base frame 11. Each mounting surface 117 is provided with a pole piece fixing seat 113, which can fix the edge pole piece 26 of the speaker device 2, so that the edge pole piece 26 can be connected to the speaker bracket 1 by embedding, thereby simplifying the structure of the speaker bracket 1 and reducing assembly costs. At the same time, by placing the pole piece fixing seat 113 on the mounting surface 117 of the receiving opening 111, the pole piece fixing seat 113 can have a larger length along the length direction of the base frame 11, thereby increasing the contact area between the pole piece fixing seat 113 and the edge pole piece 26, and thus enhancing the stability between the pole piece fixing seat 113 and the edge pole piece 26.

[0056] The partition 12 is provided with a first mounting groove 121 and a second mounting groove 122 spaced apart along the width extension direction of the base frame 11, so that the first conductive element 22 and the second conductive element 23 connecting the voice coil 21 in the two receiving ports 111 can be installed in the first mounting groove 121 and the second mounting groove 122, so as to be connected to the speaker bracket 1 by embedding, which effectively simplifies the structure of the speaker bracket 1 and reduces the assembly cost.

[0057] In summary, the speaker bracket 1 of this application fixes the edge electrode 26 with the electrode fixing seat 113, so that the edge electrode 26 can be connected to the speaker bracket 1 by embedding. At the same time, by directly setting the first mounting groove 121 and the second mounting groove 122 for mounting the first conductive element 22 and the second conductive element 23 on the speaker bracket 1, the first conductive element 22 and the second conductive element 23 for connecting the dual voice coils can be connected to the speaker bracket 1 by embedding. This effectively simplifies the structure of the speaker bracket 1 and reduces the assembly cost, and solves the problem of the large size of the speaker device 2.

[0058] In addition, since the base frame 11 is mostly made of plastic, the rigidity of the base frame 11 can be effectively increased by connecting the edge electrode 26, the first conductive element 22 and the second conductive element 23 to the speaker bracket 1 in an embedded manner, thereby improving the structural stability and load-bearing capacity of the speaker bracket 1.

[0059] See Figures 1-4 To enhance the positioning and fixing effect of the edge electrode 26, in one embodiment, the electrode fixing base 113 has a plurality of spaced first locking structures 114, and the edge electrode 26 can be fixed on the electrode fixing base 113 by the first locking structures 114.

[0060] Specifically, the edge electrode 26 may be provided with a second locking structure 27. The edge electrode 26 is disposed on the electrode holder 113, and the second locking structure 27 is engaged with the first locking structure 114 to achieve a detachable connection between the edge electrode 26 and the electrode holder 113. It can be understood that in the embodiments of this application, the first locking structure 114 is one of a groove or a protrusion structure, and the second locking structure 27 is another of a groove or a protrusion structure. The connection between the edge electrode 26 and the electrode holder 113 is achieved by inserting the protrusion into the groove.

[0061] To further ensure the fixing effect of the electrode holder 113 on the edge electrode 26, in the embodiments of this application, multiple first locking structures 114 are provided, and the multiple first locking structures 114 are spaced apart along the length extension direction of the base frame 11. Multiple second locking structures are provided, and the multiple second locking structures 114 are spaced apart along the length extension direction of the edge electrode 26, so as to further enhance the stability between the electrode holder 113 and the edge electrode 26.

[0062] To facilitate the fixing of the first lead 221 and the second lead 231 and ensure their stability on the base frame 11, in one embodiment, a lead fixing seat 112 is also provided within the receiving opening 111. By providing damping adhesive 29 on the lead fixing seat 112, the first lead 221 and the second lead 231 can be fixed on the lead fixing seat 112.

[0063] Specifically, the receiving port 111 has two mounting surfaces 117 arranged opposite to each other along the width direction of the base frame 11. Each mounting surface 117 is provided with a lead wire fixing seat 112. The lead wire fixing seats 112 on the two mounting surfaces 117 are respectively used to fix the first lead wire 221 and the second lead wire 231.

[0064] Furthermore, to simplify the structure and enhance the rigidity of the lead holder 112 and the electrode holder 113, in one embodiment, the lead holder 112 and the electrode holder 113 are connected and are both part of the holder.

[0065] See Figures 2-4 Specifically, the receiving port 111 has two oppositely arranged mounting surfaces 117 extending along the width direction of the base frame 11. Each mounting surface 117 is provided with a fixing seat. The fixing seat has a lead wire fixing surface and an electrode fixing surface that are opposite to each other extending along the thickness direction of the base frame 11. The lead wire fixing surface is located on the lead wire fixing seat 112, and the electrode fixing surface is located on the electrode fixing seat 113. This structure allows the base frame 11 to be equipped with only one fixing seat during production to achieve auxiliary fixing of the opposite electrode 26, the first lead 221, and the second lead 231, effectively simplifying the structure and reducing production costs.

[0066] See Figure 1 and Figure 3 To facilitate electrical connection with the power supply equipment, in one embodiment, the first mounting groove 121 includes two first grooves 123, so that two first conductive elements 22, which are respectively connected to two voice coils 21, can be embedded in the two first grooves 123. The two first grooves 123 are spaced apart along the length of the base frame 11, so that the two first grooves 123 are close to the two receiving openings 111, so that the two first conductive elements 22 are respectively connected to the two voice coils 21. Each first groove 123 extends through the partition 12 along the thickness of the base frame 11, so that the positive and negative terminals of the power supply equipment can be connected to the two first conductive elements 22 respectively.

[0067] Understandably, during the assembly of the aforementioned speaker bracket 1, two first conductive elements 22 can be embedded in two first grooves 123 respectively, and the two first conductive elements 22 can be connected to two voice coils 21 through two first leads 221. The second conductive element 23 can be embedded in the second mounting groove 122, and the second conductive element 23 can be connected to the two voice coils 21 through two second leads 231. Subsequently, the two voice coils 21 can be energized by connecting the positive and negative terminals of the power supply equipment to the two first conductive elements 22 respectively.

[0068] See Figure 1 and Figure 3To improve the fixing effect of the second conductive element 23, in one embodiment, the second mounting groove 122 includes a connecting channel and two second groove bodies 124. The two second groove bodies 124 are spaced apart along the length of the base frame 11, and the connecting channel connects the two second groove bodies 124. This structure can increase the contact area between the second conductive element 23 and the partition 12, thereby enhancing the stability of the second conductive element 23 fixed in the partition 12 via the second mounting groove 122.

[0069] Understandably, in the embodiments of this application, the structure of the second conductive element 23 that matches the structure of the second mounting groove 122 is as follows: the second conductive element 23 includes a connecting bend and two connecting ends, the two connecting ends being located in the slots of the two second grooves 124 respectively, the connecting bend being disposed inside the partition 12 and connected to the two connecting ends. When the second conductive element 23 is connected to the two voice coils 21 through the two second leads 231, one end of the two second leads 231 can be disposed on the two connecting ends respectively, and the other end of the two second leads 231 can be disposed on the two voice coils 21 respectively, and the current can flow sequentially through one connecting end, the connecting bend, and the other connecting end.

[0070] The above structure allows the two connecting ends to be conveniently connected to the second lead 231 by placing them in the slots of the two second grooves 124 respectively. By placing the connecting bend inside the separator 12, the stability of the second conductive element 23 within the separator 12 can be effectively enhanced.

[0071] See Figures 1-3 In one embodiment, the second groove 124 and the first groove 123 are spaced apart along the width extension direction of the base frame 11, so that when the first conductive element 22 and the second conductive element 23 are respectively installed in the first mounting groove 121 and the second mounting groove 122, the connection ends of the first conductive element 22 and the second conductive element 23 can be spaced apart along the width extension direction of the base frame 11. This not only makes the overall structure more regular, but also makes the lengths of the first lead 221 and the second lead 231 used to connect with the first conductive element 22 and the second conductive element 23 consistent, thereby significantly improving signal integrity, reducing electromagnetic interference, improving reliability, simplifying design and manufacturing, and improving the convenience of repair and maintenance.

[0072] In other words, consistent lead lengths ensure that signals have the same delay time during transmission, thereby reducing signal distortion and timing issues. Simultaneously, they reduce differences in electromagnetic radiation, lower electromagnetic interference, and improve the circuit's immunity to interference, minimizing the impact of external electromagnetic interference on the signal. Furthermore, consistent lead lengths reduce mechanical stress caused by inconsistent lengths, improve lead mechanical stability, reduce poor contact or short circuits due to length differences, enhance system reliability, simplify manufacturing processes, reduce adjustment and calibration steps during production, and increase production efficiency.

[0073] See Figure 1 , Figure 2 and Figure 5 In one embodiment, the base frame 11 has a first surface 118 and a second surface 119 that are opposite to each other along its own thickness extension direction. Each of the four corners of the first surface 118 is provided with a fixing bracket 115. The upper cover 28 of the speaker device 2 can be fixed to the first surface 118 through the fixing bracket 115 to realize the connection between the upper cover 28 and the base frame 11. This allows the upper cover 28 to effectively protect the diaphragm, voice coil 21 and magnetic circuit assembly inside the speaker device 2, prevent external objects (such as dust, moisture, etc.) from entering, ensure the normal operation of the speaker device 2 and extend its service life.

[0074] In one embodiment, along the length of the base frame 11, both sides of the second surface 119 have connecting seats 116. The connecting seats 116 have a first connecting groove on the side facing the partition 12, and the partition 12 has a second connecting groove on the side facing the connecting seats 116. The two ends of the magnetic yoke 24 of the speaker device 2 can be fixed in the first connecting groove and the second connecting groove respectively to realize the connection between the magnetic yoke 24 and the base frame 11, so that the magnetic yoke 24 can guide the magnetic flux and reduce the leakage magnetic phenomenon in the magnetic circuit.

[0075] See Figures 5-7 The embodiments of this application also provide a speaker device 2, including a speaker assembly and a speaker bracket 1 as described in any of the above embodiments, wherein the speaker assembly is disposed on the speaker bracket 1. The speaker assembly includes components such as a voice coil 21, a first conductive element 22, a second conductive element 23, a magnetic yoke 24, a magnet assembly 25, a side electrode 26, a top cover 28, and a diaphragm. The speaker bracket 1 is used to combine the various components of the speaker assembly to form the speaker device 2.

[0076] Specifically, see Figures 1-4The speaker bracket 1 includes a base frame 11 and a partition 12. The base frame 11 has an accommodating space 110 inside. The partition 12 is disposed on the base frame 11 and divides the accommodating space 110 into two accommodating openings 111 spaced apart along the length of the base frame 11. This allows the base frame 11 to accommodate two voice coils 21 through the two accommodating openings 111, thereby enabling the speaker device 2 with the speaker bracket 1 of this application to be a dual voice coil design, so that the speaker device 2 can achieve the best bass effect within a limited space.

[0077] Each receiving opening 111 is provided with a pole piece fixing seat 113, which can fix the edge pole piece 26 of the speaker device 2, so that the edge pole piece 26 can be connected to the speaker bracket 1 by embedding, thereby simplifying the structure of the speaker bracket 1 and reducing assembly costs. The pole piece fixing seat 113 can be symmetrically arranged on two opposite sides of the receiving opening 111 along the width extension direction of the base frame 11, or it can be symmetrically arranged on two opposite sides of the receiving opening 111 along the length extension direction of the base frame 11.

[0078] The partition 12 is provided with a first mounting groove 121 and a second mounting groove 122 spaced apart along the width extension direction of the base frame 11, so that the first conductive element 22 and the second conductive element 23 connecting the voice coil 21 in the two receiving ports 111 can be installed in the first mounting groove 121 and the second mounting groove 122, so as to be connected to the speaker bracket 1 by embedding, which effectively simplifies the structure of the speaker bracket 1 and reduces the assembly cost.

[0079] In summary, the speaker device 2 of this application uses the pole piece fixing seat 113 of the speaker bracket 1 to fix the edge pole piece 26, so that the edge pole piece 26 can be connected to the speaker bracket 1 by embedding. At the same time, by directly setting the first mounting groove 121 and the second mounting groove 122 for mounting the first conductive element 22 and the second conductive element 23 on the speaker bracket 1, the first conductive element 22 and the second conductive element 23 for connecting the dual voice coils can be connected to the speaker bracket 1 by embedding, thereby effectively simplifying the structure of the speaker bracket 1 and reducing the assembly cost, and solving the problem of the large size of the speaker device 2.

[0080] In one embodiment, the speaker assembly includes two voice coils 21, which are respectively located in two receiving ports 111, so that the speaker device 2 of this application is a dual voice coil design and has the effect of maximizing the bass effect in a limited space.

[0081] The first mounting slot 121 includes two first slots 123, so that two first conductive elements 22, which are respectively connected to two voice coils 21, can be embedded in the two first slots 123. The two first slots 123 are spaced apart along the length of the base frame 11. Each of the two first slots 123 is provided with a first conductive element 22, and the two first conductive elements 22 are respectively connected to the two voice coils 21 through two first leads 221. The second mounting slot 122 is provided with a second conductive element 23, and the second conductive element 23 is connected to the two voice coils 21 through two second leads 231.

[0082] Understandably, during the assembly of the aforementioned speaker bracket 1, two first conductive elements 22 can be embedded in two first grooves 123 respectively, and the two first conductive elements 22 can be connected to two voice coils 21 through two first leads 221. The second conductive element 23 can be embedded in the second mounting groove 122, and the second conductive element 23 can be connected to the two voice coils 21 through two second leads 231. Subsequently, the two voice coils 21 can be energized by connecting the positive and negative terminals of the power supply equipment to the two first conductive elements 22 respectively.

[0083] In one embodiment, the length of the first conductive element 22 extending along the thickness direction of the base frame 11 is greater than or equal to the length of the separator 12 extending along the thickness direction of the base frame 11, so that the first conductive element 22 in the first groove 123 is connected to the first lead 221.

[0084] Specifically, in one embodiment, the first groove 123 penetrates the partition 12 and has slots on both sides of the partition 12 extending along the thickness direction of the base frame 11. The length of the first conductive element 22 extending along the thickness direction of the base frame 11 is greater than the length of the partition 12 extending along the thickness direction of the base frame 11, so that the two ends of the first conductive element 22 pass through the two slots of the first groove 123 respectively, so that the first lead 221 is connected to the end of the first conductive element 22 located outside the slot.

[0085] In another embodiment, the first groove 123 penetrates the partition 12 and has slots on both sides of the partition 12 extending along the thickness direction of the base frame 11. The length of the first conductive element 22 extending along the thickness direction of the base frame 11 is equal to the length of the partition 12 extending along the thickness direction of the base frame 11, so that the two ends of the first conductive element 22 are respectively located at the two slots of the first groove 123, so that the first lead 221 can be connected to the end of the first conductive element 22 located outside the slot.

[0086] In one embodiment, the second conductive element 23 includes a connecting bend and two connecting ends. The second mounting groove 122 includes a connecting channel and two second grooves 124, which are spaced apart along the length of the base frame 11. The connecting channel connects the two second grooves 124. The two connecting ends are located within the openings of the two second grooves 124 for connection with the second wire. The connecting bend is disposed inside the separator 12 to enhance the stability of the second conductive element 23 on the separator 12. The connecting bend connects to the two connecting ends to conduct current.

[0087] When the second conductive element 23 is connected to the two voice coils 21 via two second leads 231, one end of each second lead 231 can be disposed on one of the two connection ends, and the other end of each second lead 231 can be disposed on one of the two voice coils 21. Current can flow sequentially through one connection end, the connection bend, and the other connection end. This structure facilitates the connection between the second conductive element 23 and the second leads 231 while increasing the contact area between the second conductive element 23 and the separator 12, thereby enhancing the stability of the second conductive element 23 fixed within the separator 12 via the second mounting groove 122.

[0088] See Figure 3 and Figure 7 In one embodiment, the first lead 221 is fixed to the lead fixing base 112 by damping adhesive 29 to ensure the stability of the first lead 221 after installation. The second lead 231 is fixed to the lead fixing base 112 by damping adhesive 29 to ensure the stability of the first lead 221 after installation.

[0089] See Figure 3 , Figure 4 and Figure 7 In one embodiment, the speaker assembly includes a side pole piece 26, on which a second locking structure 27 is provided. The side pole piece 26 is disposed on a pole piece fixing seat 113, and the second locking structure 27 is engaged with a first locking structure 114.

[0090] To facilitate the fixing of the edge electrode 26 of the speaker device 2 and to allow the edge electrode 26 to be connected to the speaker bracket 1 by embedding, thereby simplifying the structure of the speaker bracket 1 and reducing assembly costs, in the embodiments of this application, the receiving opening 111 has two oppositely arranged mounting surfaces 117 extending along the width direction of the base frame 11. Each mounting surface 117 is provided with an electrode fixing seat 113, and the edge electrode 26 can be fixed to the base frame 11 by the electrode fixing seat 113.

[0091] Specifically, see Figures 2-4Along the length of the base frame 11, the electrode holder 113 is provided with a plurality of first locking structures 114 at intervals, and the edge electrode 26 can be fixed to the electrode holder 113 by the plurality of first locking structures 114. More specifically, the edge electrode 26 is provided with a plurality of second locking structures 27, the edge electrode 26 is disposed on the electrode holder 113, and the plurality of second locking structures 27 are respectively engaged with the plurality of first locking structures 114 to realize a detachable connection between the edge electrode 26 and the electrode holder 113. It can be understood that in the embodiments of this application, the first locking structure 114 is one of a groove or a protrusion structure, and the second locking structure 27 is another of a groove or a protrusion structure. The edge electrode 26 and the electrode holder 113 are connected by inserting the protrusion into the groove.

[0092] In addition, since the base frame 11 is mostly made of plastic, the rigidity of the base frame 11 can be effectively increased by connecting the edge plate 26 to the speaker bracket 1 in an embedded manner, thereby improving the structural stability and load-bearing capacity of the speaker bracket 1.

[0093] Furthermore, in the embodiments of this application, the lead wire fixing seat 112 and the electrode fixing seat 113 are interconnected and are both part of the fixing seat to simplify the structure.

[0094] Specifically, the receiving port 111 has two oppositely arranged mounting surfaces 117 extending along the width direction of the base frame 11. Each mounting surface 117 is provided with a fixing seat. The fixing seat has a lead wire fixing surface and an electrode fixing surface that are opposite to each other extending along the thickness direction of the base frame 11. The lead wire fixing surface is located on the lead wire fixing seat 112, and the electrode fixing surface is located on the electrode fixing seat 113. This structure allows the base frame 11 to only need to be equipped with one fixing seat during production to achieve auxiliary fixing of the opposite electrode 26, the first lead 221, and the second lead 231, effectively simplifying the structure and reducing production costs.

[0095] See Figures 5-6 In one embodiment, the loudspeaker assembly includes two magnetic yokes 24 and two magnet assemblies 25. The two magnetic yokes 24 are both mounted on the base frame 11 and cooperate with the base frame 11 to form two receiving spaces. The two receiving spaces are respectively connected to two receiving ports 111 so that components such as the magnetic yokes 24, magnet assemblies 25, edge plates 26, and voice coils 21 can be accommodated in the receiving spaces and receiving ports 111.

[0096] Two magnet assemblies 25 are respectively disposed in two receiving spaces and extend along the length of the base frame 11. Both sides of the magnet assembly 25 have gaps with the yoke 24 so as to dissipate heat from the magnet assembly 25 and the voice coil 21 and other components located in the yoke 24.

[0097] Specifically, the base frame 11 has a first surface 118 and a second surface 119 that are opposite to each other along its own thickness extension direction. The second surface 119 has a connecting seat 116 on both sides along the length extension direction of the base frame 11. The connecting seat 116 has a first connecting groove on the side facing the partition 12, and the partition 12 has a second connecting groove on the side facing the connecting seat 116. The two ends of the magnetic yoke 24 are respectively fixed in the first connecting groove and the second connecting groove to realize the connection between the magnetic yoke 24 and the base frame 11.

[0098] More specifically, the magnetic yoke 24 includes a first connecting part and two second connecting parts. The two second connecting parts are respectively disposed in the first connecting groove and the second connecting groove. The first connecting part connects the two second connecting parts. The accommodating space is formed by the base frame 11 cooperating with the first connecting part and the two second connecting parts.

[0099] The first connecting portion is parallel to the second surface 119, allowing the magnet assembly 25 to connect with the first connecting portion. The first connecting portion and the second surface 119 are spaced apart along the thickness extension direction of the base frame 11, so that the yoke 24 can cooperate with the base frame 11 to form a large accommodating space. The magnet assembly 25 has gaps between its two sides and the two second connecting portions along the length extension direction of the base frame 11, allowing external air to circulate through these gaps, thereby providing auxiliary heat dissipation for components such as the magnet assembly 25 and voice coil 21 located within the yoke 24.

[0100] See Figures 5-7 In one embodiment, the magnet assembly 25 includes a main magnet 251 and two auxiliary magnets 252, with the main magnet 251 spaced apart between the two auxiliary magnets 252 along the width of the base 11. The combination of the main magnet 251 and the two auxiliary magnets 252 significantly enhances the magnetic field strength of the speaker assembly's magnetic circuit, thereby improving the vibration efficiency of the voice coil 21.

[0101] Specifically, the main magnet 251 is disposed on the first connecting part of the yoke 24, and there are gaps between the two sides of the main magnet 251 and the two second connecting parts of the yoke 24 respectively along the length extension direction of the base frame 11, so that external air can circulate and dissipate heat through the gaps. A washer is provided on the side of the main magnet 251 away from the first connecting part to enhance the magnetic flux density of the magnetic circuit and reduce the leakage magnetic phenomenon in the magnetic circuit. The voice coil 21 is sleeved on the outside of the main magnet 251.

[0102] Two auxiliary magnets 252 are each disposed on the first connecting portion of the yoke 24, and gaps are respectively formed between the two auxiliary magnets 252 and the two second connecting portions of the yoke 24 on both sides extending along the length of the base frame 11, so that external air can circulate and dissipate heat through the gaps. The side of the auxiliary magnets 252 facing away from the first connecting portion is connected to the side pole piece 26, so that the side pole piece 26 can be used in conjunction with the magnet assembly 25 and the washer to enhance the magnetic flux density of the magnetic circuit and improve the efficiency of the magnetic circuit.

[0103] In one embodiment, the speaker assembly includes a top cover 28, which is secured to the first surface 118 by a fixing bracket 115 to achieve the connection between the top cover 28 and the base frame 11. This allows the top cover 28 to effectively protect the diaphragm, voice coil 21 and magnetic circuit assembly inside the speaker device 2, prevent external objects (such as dust, moisture, etc.) from entering, ensure the normal operation of the speaker device 2 and extend its service life.

[0104] Specifically, the base frame 11 has a first surface 118 and a second surface 119 that are opposite to each other along its own thickness extension direction. Each of the four corners of the first surface 118 is provided with a fixing seat 115, and the four corners of the upper cover 28 are respectively fixedly connected to the four fixing seats 115.

[0105] See Figure 8 The embodiments of this application also provide a smart glasses 3, including a glasses body 31 and a speaker device 2 as described in any of the above embodiments, wherein the speaker device 2 is disposed inside the glasses body 31. Specifically, the glasses body 31 has temples, and the speaker device 2 is disposed inside the temples.

[0106] Specifically, see Figures 5-7 The loudspeaker assembly includes components such as a voice coil 21, a first conductive element 22, a second conductive element 23, a magnetic yoke 24, a magnet assembly 25, a side pole piece 26, a top cover 28, and a diaphragm. The loudspeaker bracket 1 is used to combine the various components of the loudspeaker assembly to form a sound-generating device 2.

[0107] The speaker bracket 1 includes a base frame 11 and a partition 12. The base frame 11 has an accommodating space 110 inside. The partition 12 is disposed on the base frame 11 and divides the accommodating space 110 into two accommodating openings 111 spaced apart along the length of the base frame 11. This allows the base frame 11 to accommodate two voice coils 21 through the two accommodating openings 111, thereby enabling the speaker device 2 with the speaker bracket 1 of this application to be a dual voice coil design, so that the speaker device 2 can achieve the best bass effect within a limited space.

[0108] Each receiving opening 111 is provided with a pole piece fixing seat 113, which can fix the edge pole piece 26 of the speaker device 2, so that the edge pole piece 26 can be connected to the speaker bracket 1 by embedding, thereby simplifying the structure of the speaker bracket 1 and reducing assembly costs. The pole piece fixing seat 113 can be symmetrically arranged on two opposite sides of the receiving opening 111 along the width extension direction of the base frame 11, or it can be symmetrically arranged on two opposite sides of the receiving opening 111 along the length extension direction of the base frame 11.

[0109] The partition 12 is provided with a first mounting groove 121 and a second mounting groove 122 spaced apart along the width extension direction of the base frame 11, so that the first conductive element 22 and the second conductive element 23 connecting the voice coil 21 in the two receiving ports 111 can be installed in the first mounting groove 121 and the second mounting groove 122, so as to be connected to the speaker bracket 1 by embedding, which effectively simplifies the structure of the speaker bracket 1 and reduces the assembly cost.

[0110] In summary, the smart glasses 3 of this application uses the electrode fixing seat 113 of the speaker bracket 1 to fix the edge electrode 26, so that the edge electrode 26 can be connected to the speaker bracket 1 by embedding. At the same time, by directly setting the first mounting groove 121 and the second mounting groove 122 for mounting the first conductive element 22 and the second conductive element 23 on the speaker bracket 1, the first conductive element 22 and the second conductive element 23 for connecting the dual voice coils can be connected to the speaker bracket 1 by embedding, thereby effectively simplifying the structure of the speaker bracket 1 and reducing the assembly cost, and solving the problem of the large size of the speaker device 2.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
