[0055] Referring to Figures 1-4 , an embodiment of the present application provides, according to one aspect of the present application, a conductive bracket 1, including a bracket body 11 and a separator 12. Among them, an accommodation space 110 is provided inside the bracket body 11, and the separator 12 is disposed on the bracket body 11 and divides the accommodation space 110 into two accommodation openings 111 spaced along the length extension direction of the bracket body 11, so that the bracket body 11 can be provided with two voice coils 21 through the two accommodation openings 111. Furthermore, the loudspeaker device 2 equipped with the conductive bracket 1 of the present application can be designed with a dual voice coil, so that the loudspeaker device 2 has the effect of bringing the bass effect to the best state within a limited space.

[0056] A pole piece fixing seat 113 is provided in each accommodation opening 111. The pole piece fixing seat 113 can fix the edge pole piece 26 of the loudspeaker device 2, so that the edge pole piece 26 can be connected to the conductive bracket 1 by means of embedding, so as to simplify the structure of the conductive bracket 1 and reduce the assembly cost. Among them, the pole piece fixing seats 113 can be symmetrically disposed on two opposite side surfaces of the accommodation opening 111 along the width extension direction of the bracket body 11, or can be symmetrically disposed on two opposite side surfaces of the accommodation opening 111 along the length extension direction of the bracket body 11.

[0057] The separator 12 is provided with a first installation groove 121 and a second installation groove 122 spaced along the width extension direction of the bracket body 11, so that the first conductive member 22 and the second conductive member 23 connecting the voice coils 21 in the two accommodation openings 111 can be installed in the first installation groove 121 and the second installation groove 122, so as to be connected to the conductive bracket 1 by means of embedding, effectively simplifying the structure of the conductive bracket 1 and reducing the assembly cost.

[0058] Specifically, the first installation groove 121 includes two first groove bodies 123, so that the two first conductive members 22 respectively connected to the two voice coils 21 can be respectively embedded in the two first groove bodies 123. The two first groove bodies 123 are spaced along the length extension direction of the bracket body 11, so that the two first groove bodies 123 can be respectively close to the two accommodation openings 111, so that the two first conductive members 22 can be respectively connected to the two voice coils 21. Each first groove body 123 penetrates through the separator 12 along the thickness extension direction of the bracket body 11, so that the positive and negative poles of the power supply device can be respectively connected to the two first conductive members 22.

[0059] That is, when the above conductive bracket 1 is assembled, the two first conductive members 22 can be respectively embedded in the two first grooves 123, and the two first conductive members 22 are connected to the two voice coils 21 through the two first leads 221. The second conductive member 23 is embedded in the second mounting groove 122, and the second conductive member 23 is connected to the two voice coils 21 through the two second leads 231. Subsequently, the positive and negative electrodes of the power supply device can be respectively connected to the two first conductive members 22 to energize the two voice coils 21.

[0060] In summary, for the conductive bracket 1 of the present application, the side pole piece 26 is fixed by the pole piece fixing seat 113, so that the side pole piece 26 can be connected to the conductive bracket 1 by embedding. At the same time, the first mounting groove 121 and the second mounting groove 122 for mounting the first conductive member 22 and the second conductive member 23 are directly provided on the conductive bracket 1, so that the first conductive member 22 and the second conductive member 23 for connecting the double voice coils can be connected to the conductive bracket 1 by embedding, thereby effectively simplifying the structure of the conductive bracket 1 and reducing the assembly cost, and solving the problem of the large volume of the sound generating device 2.

[0061] In addition, since the frame body 11 is mostly made of plastic material, by connecting the side pole piece 26, the first conductive member 22 and the second conductive member 23 to the conductive bracket 1 by embedding, the rigidity of the frame body 11 can be effectively increased, and the structural stability and bearing capacity of the conductive bracket 1 can be improved.

[0062] Refer to Figures 1-4 , in order to enhance the positioning and fixing effect of the side pole piece 26, in one embodiment, the pole piece fixing seat 113 has a plurality of first clamping structures 114 arranged at intervals, and the side pole piece 26 can be fixed on the pole piece fixing seat 113 through the first clamping structures 114.

[0063] Specifically, the side pole piece 26 can be provided with a second clamping structure 27. The side pole piece 26 is arranged on the pole piece fixing seat 113, and the second clamping structure 27 is clamped and connected with the first clamping structure 114 to realize the detachable connection between the side pole piece 26 and the pole piece fixing seat 113. It can be understood that in the embodiment of the present application, the first clamping structure 114 is one of a groove or a convex block structure, and the second clamping structure 27 is the other of a groove or a convex block structure. The connection between the side pole piece 26 and the pole piece fixing seat 113 is realized by inserting the convex block into the groove.

[0064] To further ensure the fixing effect of the edge pole piece 26 by the pole piece fixing seat 113, in one embodiment, the accommodating opening 111 has two opposite mounting surfaces along the width extension direction of the frame body 11, and a pole piece fixing seat 113 is provided on each mounting surface. This structure enables the pole piece fixing seat 113 to have a relatively large length along the length extension direction of the frame body 11, so as to increase the contact area between the pole piece fixing seat 113 and the edge pole piece 26, and further enhance the stability between the pole piece fixing seat 113 and the edge pole piece 26.

[0065] In addition, in the embodiments of the present application, there are multiple first clamping structures, and the multiple first clamping structures 114 are arranged at intervals along the length extension direction of the frame body 11. There are multiple second clamping structures, and the multiple second clamping structures 114 are arranged at intervals along the length extension direction of the edge pole piece 26 to further enhance the stability between the pole piece fixing seat 113 and the edge pole piece 26.

[0066] To facilitate the fixing of the first lead 221 and the second lead 231 and ensure the stability of the first lead 221 and the second lead 231 on the frame body 11. In one embodiment, a lead fixing seat 112 is further provided in the accommodating opening 111. By providing damping glue 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.

[0067] Specifically, the accommodating opening 111 has two opposite mounting surfaces along the width extension direction of the frame body 11, and a lead fixing seat 112 is provided on each mounting surface. The lead fixing seats 112 on the two mounting surfaces are respectively used to fix the first lead 221 and the second lead 231.

[0068] Furthermore, to simplify the structure and enhance the rigidity of the lead fixing seat 112 and the pole piece fixing seat 113. In one embodiment, the lead fixing seat 112 is connected to the pole piece fixing seat 113, and both are part of the fixing seat.

[0069] Refer to Figures 2-4 , specifically, the accommodating opening 111 has two opposite mounting surfaces along the width extension direction of the frame body 11, and a fixing seat is provided on each mounting surface. The fixing seat has a lead fixing surface and a pole piece fixing surface that face away from each other along the thickness extension direction of the frame body 11. The lead fixing surface is located on the lead fixing seat 112, and the pole piece fixing surface is located on the pole piece fixing seat 113. This structure enables the frame body 11 to only need to set one fixing seat during production to realize the auxiliary fixing of the edge pole piece 26, the first lead 221, and the second lead 231, effectively simplifying the structure and reducing the production cost.

[0070] Refer to Figure 1 , Figure 3 and Figure 8, in order to improve the fixing effect on the second conductive member 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 arranged at intervals along the length extension direction of the frame body 11, and the connecting channel communicates with the two second groove bodies 124. This structure can increase the contact area between the second conductive member 23 and the partition member 12, thereby enhancing the stability of the second conductive member 23 fixed in the partition member 12 through the second mounting groove 122.

[0071] It can be understood that in the embodiment of the present application, the structure of the second conductive member 23 matching the structure of the second mounting groove 122 is: the second conductive member 23 includes a connecting bending portion 232 and two connecting end portions 233. The two connecting end portions 233 are respectively located in the openings of the two second groove bodies 124, and the connecting bending portion 232 is arranged inside the partition member 12 and is connected to the two connecting end portions 233. When the second conductive member 23 is connected to the two voice coils 21 through the two second leads 231, one ends of the two second leads 231 can be respectively arranged on the two connecting end portions 233, and the other ends of the two second leads 231 can be respectively arranged on the two voice coils 21, and the current can flow sequentially through a connecting end portion 233, the connecting bending portion 232, and the other connecting end portion 233.

[0072] By arranging the two connecting end portions 233 respectively in the openings of the two second groove bodies 124, the above structure can facilitate the connection between the connecting end portion 233 and the second lead 231. By arranging the connecting bending portion 232 inside the partition member 12, the stability of the second conductive member 23 in the partition member 12 can be effectively enhanced.

[0073] Refer to Figures 1-3 , in one embodiment, the second groove body 124 and the first groove body 123 are arranged at intervals along the width extension direction of the frame body 11, so that when the first conductive member 22 and the second conductive member 23 are respectively installed in the first mounting groove 121 and the second mounting groove 122, the connecting end portions 233 of the first conductive member 22 and the second conductive member 23 can be arranged at intervals along the width extension direction of the frame body 11. This not only makes the overall structure more regular, but also enables the lengths of the first lead 221 and the second lead 231 respectively used to connect the first conductive member 22 and the second conductive member 23 to be the same, so as to significantly improve signal integrity, reduce electromagnetic interference, improve reliability, simplify design and manufacturing, and improve the convenience of maintenance and repair.

[0074] It can be understood that consistent lead lengths can ensure that signals have the same delay time during transmission, thereby reducing signal distortion and timing issues; at the same time, it can reduce the differences in electromagnetic radiation, lower electromagnetic interference, contribute to improving the anti-interference ability of the circuit, and reduce the impact of external electromagnetic interference on signals. In addition, consistent lead lengths can also reduce mechanical stress caused by inconsistent lengths, improve the mechanical stability of the leads, reduce problems such as poor contact or short circuits caused by length differences, improve the reliability of the system, simplify the manufacturing process, reduce adjustment and calibration steps during production, and improve production efficiency. Therefore, the above structure makes the lengths of the first lead 221 and the second lead 231 consistent to significantly improve signal integrity, reduce electromagnetic interference, improve reliability, simplify design and manufacturing, and improve the convenience of repair and maintenance.

[0075] Refer to Figure 1 、 Figure 2 and Figure 5 In one embodiment, the frame 11 has a first surface 118 and a second surface 119 that extend away from each other along the thickness extension direction of the frame itself. Fixed clamping seats 115 are provided at the four corners of the first surface 118. The upper cover 28 of the sound generating device 2 can be clamped to the first surface 118 through the fixed clamping seats 115 to achieve the connection between the upper cover 28 and the frame 11, so that the upper cover 28 can effectively protect the diaphragm, voice coil 21, and magnetic circuit components inside the sound generating device 2, prevent external objects (such as dust, moisture, etc.) from entering, and ensure the normal operation of the sound generating device 2 and extend its service life.

[0076] In one embodiment, along the length extension direction of the frame 11, both sides of the second surface 119 have connection seats 116. A first connection groove 117 is provided on the side of the connection seat 116 facing the partition 12, and a second connection groove 125 is provided on the side of the partition 12 facing the connection seat 116. Both ends of the yoke 24 of the sound generating device 2 can be respectively fixed in the first connection groove 117 and the second connection groove 125 to achieve the connection between the yoke 24 and the frame 11, so that the yoke 24 can guide magnetic flux and reduce magnetic leakage in the magnetic circuit.

[0077] Refer to Figures 5-7 In an embodiment of the present application, a sound generating device 2 is further provided, including a speaker assembly and a conductive bracket 1 as described in any one of the above embodiments. The speaker assembly is disposed on the conductive bracket 1. Among them, the speaker assembly includes components such as a voice coil 21, a first conductive member 22, a second conductive member 23, a yoke 24, a magnet assembly 25, a side pole piece 26, an upper cover 28, and a diaphragm. The conductive bracket 1 is used to combine the components of the speaker assembly to generate the sound generating device 2.

[0078] Specifically, refer to Figures 1-4, the conductive bracket 1 includes a bracket body 11 and a partition member 12. An accommodation space 110 is provided inside the bracket body 11. The partition member 12 is disposed on the bracket body 11 and divides the accommodation space 110 into two accommodation openings 111 spaced apart along the length extension direction of the bracket body 11, so that the bracket body 11 can be provided with two voice coils 21 through the two accommodation openings 111. Furthermore, the loudspeaker device 2 equipped with the conductive bracket 1 of the present application can be designed with a dual voice coil, enabling the loudspeaker device 2 to achieve the best effect of low bass in a limited space.

[0079] A pole piece fixing seat 113 is provided in each accommodation opening 111. The pole piece fixing seat 113 can fix the edge pole piece 26 of the loudspeaker device 2, enabling the edge pole piece 26 to be connected to the conductive bracket 1 by embedding, so as to simplify the structure of the conductive bracket 1 and reduce the assembly cost. Among them, the pole piece fixing seats 113 can be symmetrically disposed on two opposite side surfaces of the accommodation opening 111 along the width extension direction of the bracket body 11, or can be symmetrically disposed on two opposite side surfaces of the accommodation opening 111 along the length extension direction of the bracket body 11.

[0080] The partition member 12 is provided with a first installation groove 121 and a second installation groove 122 spaced apart along the width extension direction of the bracket body 11, so that the first conductive member 22 and the second conductive member 23 connecting the voice coils 21 in the two accommodation openings 111 can be installed in the first installation groove 121 and the second installation groove 122, and be connected to the conductive bracket 1 by embedding, effectively simplifying the structure of the conductive bracket 1 and reducing the assembly cost.

[0081] In summary, for the loudspeaker device 2 of the present application, the pole piece fixing seat 113 of the conductive bracket 1 is used to fix the edge pole piece 26, enabling the edge pole piece 26 to be connected to the conductive bracket 1 by embedding. At the same time, the first installation groove 121 and the second installation groove 122 for installing the first conductive member 22 and the second conductive member 23 are directly provided on the conductive bracket 1, so that the first conductive member 22 and the second conductive member 23 for connecting the dual voice coils can be connected to the conductive bracket 1 by embedding, thereby effectively simplifying the structure of the conductive bracket 1 and reducing the assembly cost, and solving the problem of the large volume of the loudspeaker device 2.

[0082] In one embodiment, the speaker assembly includes two voice coils 21, and the two voice coils 21 are respectively located in the two accommodation openings 111, so that the loudspeaker device 2 of the present application is designed with a dual voice coil and has the effect of achieving the best state of low bass in a limited space.

[0083] The first installation groove 121 includes two first groove bodies 123, so that two first conductive members 22 respectively connected to two voice coils 21 can be respectively embedded in the two first groove bodies 123. The two first groove bodies 123 are arranged at intervals along the length extension direction of the frame body 11. The two first groove bodies 123 are both provided with first conductive members 22, and the two first conductive members 22 are respectively connected to the two voice coils 21 through two first leads 221. A second conductive member 23 is arranged in the second installation groove 122, and the second conductive member 23 is connected to the two voice coils 21 through two second leads 231.

Subsequently, the positive and negative electrodes of the power supply device can be respectively connected to the two first conductive members 22 to realize the energization of the two voice coils 21.

[0085] In one embodiment, the length of the first conductive member 22 along the thickness extension direction of the frame body 11 is greater than or equal to the length of the partition member 12 along the thickness extension direction of the frame body 11, so that the first conductive member 22 in the first groove body 123 can be connected to the first lead 221.

The length of the first conductive member 22 along the thickness extension direction of the frame body 11 is greater than the length of the partition member 12 along the thickness extension direction of the frame body 11, so that both ends of the first conductive member 22 respectively pass through the two notches of the first groove body 123, so that the first lead 221 can be connected to the end of the first conductive member 22 located outside the notch.

[0087] In another embodiment, the first groove body 123 penetrates through the partition member 12 and has notches on both sides of the partition member 12 along the thickness extension direction of the frame body 11. The length of the first conductive member 22 along the thickness extension direction of the frame body 11 is equal to the length of the partition member 12 along the thickness extension direction of the frame body 11, so that both ends of the first conductive member 22 are respectively located at the two notches of the first groove body 123, so that the first lead 221 can be connected to the end of the first conductive member 22 located outside the notch.

[0088] Refer to Figure 1 、 Figure 3 and Figure 8, in one embodiment, the second conductive member 23 includes a connecting bent portion 232 and two connecting end portions 233. The second mounting groove 122 includes a connecting channel and two second groove bodies 124. The two second groove bodies 124 are arranged at intervals along the length extending direction of the frame body 11, and the connecting channel communicates with the two second groove bodies 124. The two connecting end portions 233 are respectively located within the openings of the two second groove bodies 124 for connection to the second wire. The connecting bent portion 232 is arranged inside the partition member 12 to enhance the stability of the second conductive member 23 on the partition member 12. The connecting bent portion 232 is connected to the two connecting end portions 233 to conduct current.

[0089] When the second conductive member 23 is connected to the two voice coils 21 through the two second leads 231, one ends of the two second leads 231 can be respectively arranged on the two connecting end portions 233, and the other ends of the two second leads 231 can be respectively arranged on the two voice coils 21. The current can flow sequentially through a connecting end portion 233, the connecting bent portion 232, and the other connecting end portion 233. The above structure can facilitate the connection between the second conductive member 23 and the second lead 231 while increasing the contact area between the second conductive member 23 and the partition member 12, thereby enhancing the stability of the second conductive member 23 fixed in the partition member 12 through the second mounting groove 122.

[0090] Refer to Figure 3 and Figure 7 , in one embodiment, the first lead 221 is fixed to the lead fixing seat 112 through the damping glue 29 to ensure the stability of the first lead 221 after installation. The second lead 231 is fixed to the lead fixing seat 112 through the damping glue 29 to ensure the stability of the first lead 221 after installation.

[0091] Refer to Figure 3 , Figure 4 and Figure 7 , in one embodiment, the speaker assembly includes a side pole piece 26. The side pole piece 26 is provided with a second clamping structure 27. The side pole piece 26 is arranged on the pole piece fixing seat 113, and the second clamping structure 27 is clamped and connected to the first clamping structure 114.

[0092] To facilitate the fixation of the side pole piece 26 of the sound generating device 2 and enable the side pole piece 26 to be connected to the conductive bracket 1 in a buried manner, so as to simplify the structure of the conductive bracket 1 and reduce the assembly cost. In the embodiment of the present application, the accommodating opening 111 has two opposite mounting surfaces along the width extending direction of the frame body 11. Each mounting surface is provided with a pole piece fixing seat 113, and the side pole piece 26 can be fixed to the frame body 11 through the pole piece fixing seat 113.

More specifically, a plurality of second fixing structures 27 are arranged on the side pole piece 26, the side pole piece 26 is arranged on the pole piece fixing seat 113, and the plurality of second fixing structures 27 are respectively connected with the plurality of first fixing structures 114 to realize the detachable connection between the side pole piece 26 and the pole piece fixing seat 113. It can be understood that in the embodiment of the present application, the first fixing structure 114 is one of the groove or the protrusion structure, and the second fixing structure 27 is the other of the groove or the protrusion structure, and the side pole piece 26 and the pole piece fixing seat 113 are connected by inserting the protrusion into the groove.

[0094] In addition, since the frame 11 is mostly made of plastic, the rigidity of the frame 11 can be effectively increased by connecting the side electrode 26 to the conductive support 1 in an embedded manner, thereby improving the structural stability and load-bearing capacity of the conductive support 1 .

[0095] Furthermore, in the embodiment of the present application, the lead fixing seat 112 and the pole piece fixing seat 113 are connected to each other and are both part of the fixing seat to simplify the structure.

The fixing seat has a lead fixing surface and a pole piece fixing surface which are opposite to each other along the thickness extension direction of the frame 11. The lead fixing surface is located on the lead fixing seat 112, and the pole piece fixing surface is located on the pole piece fixing seat 113. This structure allows the frame 11 to only need to be provided with one fixing seat during production to achieve auxiliary fixing of the opposite pole piece 26, the first lead 221 and the second lead 231, thereby effectively simplifying the structure and reducing production costs.
