Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] At present, the lead wires of the voice coil on the speaker and the external wires connected to the signal source are fixed on the wiring terminals respectively, and the external electrical signals are received through the wiring terminals and then transmitted to the voice coil. In the related art, the wiring terminals can only be set on the basin frame in a specific direction. If they are installed incorrectly, they need to be disassembled and reassembled, which is time-consuming and laborious.

[0037] Based on the above problems, the present invention provides a basin frame assembly 10 .

[0038] Combined with reference Figures 1 to 3 In one embodiment of the present invention, the basin frame assembly 10 includes a basin frame 1 and a terminal block 2, and at least two mounting seats 11 are provided on the side of the basin frame 1; the terminal block 2 includes a fixed structure 21 and two wiring structures 22, and the fixed structure 21 is centrally symmetrically arranged, and the fixed structure 21 is connected to the mounting seat 11; the two wiring structures 22 are respectively connected to the two ends of the fixed structure 21, and the wiring structure 22 is provided with a first wiring portion 221 for connecting the lead wire 201 of the voice coil 20 and a second wiring portion 222 for connecting the external wire 30.

[0039] The frame assembly 10 serves as the installation base for components such as the voice coil 20, diaphragm and magnetic circuit system in the speaker 100, and includes a frame 1 and two wiring terminals 2 connected to the frame 1. At least two mounting seats 11 are provided on the frame 1, and the two wiring terminals 2 are respectively connected to the two mounting seats 11 in a one-to-one correspondence.

[0040] In this embodiment, the terminal block 2 includes a fixing structure 21 for connecting to the mounting seat 11 and a wiring structure 22 for connecting the lead wire 201 of the voice coil 20 and the external wire 30. Each wiring structure 22 is provided with a first wiring portion 221 for connecting the lead wire 201 of the voice coil 20 and a second wiring portion 222 for connecting the external wire 30. Optionally, the first wiring portion 221 can be set as a soldering pad or a threading hole; the second wiring portion 222 can be set as a soldering pad or a threading hole. When the basin frame assembly 10 is applied to the speaker 100, the lead wire 201 of the voice coil 20 is connected to the first wiring portion 221 of one of the wiring structures 22, and the external wire 30 of the speaker 100 is connected to the second wiring portion 222 of the other wiring structure 22.

[0041] Among them, the fixed structure 21 and the mounting seat 11 can be connected to each other by snapping, plugging, bolting, injection molding or other methods. The present application sets the fixed structure 21 as a central symmetrical structure. In this way, when the installation direction of the two wiring structures 22 is reversed, the fixed structure 21 can also adapt to and connect with the mounting seat 11. For example, when the fixed structure 21 is plugged and matched with the mounting seat 11, one of the rectangular groove and the rectangular protrusion is set on the fixed structure 21, and the other of the rectangular groove and the rectangular protrusion is set on the mounting seat 11. Even if the wiring terminal 2 is reversed, the rectangular protrusion can be inserted in the rectangular groove. Alternatively, when the fixed structure 21 and the mounting seat 11 are connected by bolts, two fixing holes set in a central symmetrical manner can be set on the fixed structure 21, and two mounting holes set in a central symmetrical manner can be set on the mounting seat 11. Even if the installation direction of the wiring terminal 2 is reversed, the two fixing holes and the two mounting holes can be made to correspond one to one. Of course, the fixed structure 21 can also be set as the structure in the following embodiment or other structures, which are not limited here.

[0042] That is, the technical solution of the present invention is to set the fixed structure 21 of the terminal block 2 as a centrally symmetrical structure, and to make the two wiring structures 22 at both ends of the fixed structure 21 both be provided with a first wiring portion 221 for connecting the lead wire 201 of the voice coil 20 and a second wiring portion 222 for connecting the external wire 30. In this arrangement, when the installation directions of the two wiring structures 22 are reversed, the fixed structure 21 can still be connected to the mounting seat 11, and the two wiring structures 22 can also be respectively connected to the voice coil 20 lead wire 201 of the voice coil 20 and the external wire 30 of the speaker 100, so that there is no need to identify the installation direction when installing the terminal block 2, and there is no problem of reverse installation, thereby improving the installation convenience of the terminal block 2 in the basin frame assembly 10.

[0043] In one embodiment, the wiring terminal 2 is snap-fitted with the mounting seat 11. The snap-fitting method can make the connection between the wiring terminal 2 and the mounting seat 11 more stable, without the need for bolts or other tools to assist in installation, thereby improving the convenience of disassembly and assembly of the wiring terminal 2. Optionally, a card interface can be provided on the wiring terminal 2, and a snap-fitting structure can be provided on the mounting seat 11, and the snap-fitting structure is inserted into the card interface. For example, in the following embodiment, a snap-fitting protrusion 113 can be provided on the mounting seat 11, and the snap-fitting protrusion 113 is inserted into the first limiting hole 214 of the bending portion and abuts against the surface of the wiring structure 22. Alternatively, a snap-fitting boss is provided on the inner surface of the bending portion, and a slot is provided on the surface of the mounting seat 11, and the snap-fitting boss is inserted into the slot, which can also make the wiring terminal 2 snap-fitted with the mounting seat 11; other methods are not described here.

[0044] Combined with reference Figure 3 and Figure 4 In one embodiment, the fixing structure 21 includes a top plate 211 and two bent sections 212 respectively connected to the two ends of the top plate 211, the bent sections 212 are arranged at an angle with the top plate 211, the top plate 211 and the two bent sections 212 are enclosed to form a snap-in groove 213, and the mounting seat 11 is embedded in the snap-in groove 213; the wiring structure 22 is connected to one end of the bending portion away from the top plate 211, and is extended in a direction away from the other wiring structure 22.

[0045] In this embodiment, the terminal block 2 can be set as a sheet metal stamping part, or can be formed by injection molding or the like. The fixing structure 21 of the terminal block 2 includes a top plate 211 and two bent sections 212 that enclose a clamping groove 213. The fixing structure 21 can be covered on at least part of the mounting seat 11, so that at least part of the mounting seat 11 is embedded in the clamping groove 213, which can improve the position stability of the terminal block 2 fixed to the mounting seat 11, and the connection strength between the terminal block 2 and the mounting seat 11, and reduce the risk of displacement of the terminal block 2 in its length direction.

[0046] Optionally, in this embodiment, a snap-fit ​​protrusion 113 may be provided on the mounting seat 11, and the snap-fit ​​protrusion 113 is inserted into the limiting hole of the bent portion, wherein the limiting hole may be provided as the first limiting hole 214 in the following embodiment, so that the snap-fit ​​protrusion 113 abuts against the surface of the wiring structure 22; or, the limiting hole does not extend to the position of the wiring structure 22, and the snap-fit ​​protrusion 113 abuts against the hole wall of the limiting hole for limiting. In addition, a snap-fit ​​boss may be provided on the inner surface of the bent portion, and a slot may be provided on the surface of the mounting seat 11, and the snap-fit ​​boss may be inserted into the slot, so that the wiring terminal 2 may be snap-fitted with the mounting seat 11.

[0047] Combined with reference Figures 3 to 7In one embodiment, the bending section 212 is provided with a first limiting hole 214 extending to the wiring structure 22, and the wiring structure 22 is provided with a second limiting hole 223 connected to the first limiting hole 214; the mounting seat 11 includes a main body 111 and two plug-in parts 112, the two plug-in parts 112 are protruding on two sides of the main body 111 that are back to back, the main body 111 is embedded in the clamping groove 213, and the plug-in parts 112 are passed through the first limiting hole 214 and the second limiting hole 223.

[0048] In this embodiment, when the wiring terminal 2 is connected to the basin frame 1, the snap-in groove 213 of the wiring terminal 2 is opposite to the main body 111 of the mounting seat 11, so that the wiring terminal 2 is sleeved on the mounting seat 11. During this process, the plug-in portion 112 is passed through the second limiting hole 223 and enters the first limiting hole 214. This setting method can further limit the wiring terminal 2, reduce the risk of displacement of the wiring terminal 2, and improve the overall structural stability of the basin frame 1 structure.

[0049] Combined with reference Figure 2 and Figure 6 In one embodiment, a surface of the plug-in portion 112 facing away from the main body is provided with a snap-in protrusion 113 , and the snap-in protrusion 113 abuts against a surface of the wiring structure 22 facing the bending section 212 .

[0050] In this embodiment, a snap-in protrusion 113 is provided on the surface of the plug-in portion 112. When the wiring terminal 2 is fixed to the mounting seat 11, the snap-in protrusion 113 is located on the side of the wiring structure 22 facing the bending section 212, and is used to limit the wiring terminal 2 to prevent the wiring terminal 2 from detaching from the mounting seat 11, thereby improving the connection strength and stability between the wiring terminal 2 and the basin frame 1.

[0051] It can be understood that in this embodiment, the terminal block 2 has a certain bending and deformation ability, and the two wiring structures 22 can be bent to make the wiring structure 22 and the bending portion warp and deform outward, so that the snap-fit ​​protrusion 113 passes through the second limiting hole 223, which facilitates the disassembly and assembly of the terminal block 2.

[0052] Combined with reference Figure 3 and Figure 6 In one embodiment, a limiting groove 114 is provided on the surface of the mounting seat 11 facing the top plate 211, and the top plate 211 is limited in the limiting groove 114. In this arrangement, the limiting groove 114 can limit the top plate 211.

[0053] See also Figure 7 In one embodiment, the first wiring portion 221 includes a first threading hole 2211 and an avoidance channel 2212 connected to each other, and the avoidance channel 2212 runs from the first threading hole 2211 to the edge of the wiring structure 22 .

[0054] In this embodiment, one end of the lead wire 201 of the voice coil 20 is inserted into the first threading hole 2211, which improves the connection strength between the lead wire 201 and the terminal 2. The lead wire 201 and the terminal 2 are not easily separated, and a stable electrical connection can be maintained, thereby improving the overall performance stability. Optionally, the lead wire 201 can be welded to the terminal 2 or connected by a conductive adhesive or other structure.

[0055] Furthermore, an avoidance channel 2212 is provided on the wiring structure 22. It can be understood that the lead wire 201 of the voice coil 20 passes out from the inner side of the basin frame 1 to extend to the position of the wiring terminal 2. The avoidance channel 2212 is provided so that the wiring terminal 2 can enter the first threading hole 2211 through the avoidance channel 2212 from the side of the wiring structure 22, and there is no need to penetrate the first threading hole 2211 on the back side of the wiring terminal 2, thereby improving the convenience of connecting the lead wire 201 and the first threading hole 2211.

[0056] See also Figure 7 In one embodiment, the second wiring portion 222 is configured as a second threading hole 2221. One end of the external wire 30 of the speaker 100 is passed through the second threading hole 2221, thereby improving the connection strength between the external wire 30 and the wiring terminal 2. The external wire 30 and the wiring terminal 2 are not easily separated, and a stable electrical connection can be maintained, thereby improving the overall performance stability. Optionally, the external wire 30 can be connected to the wiring terminal 2 by welding or by a conductive adhesive or other structure.

[0057] Combined with reference Figure 1 and Figure 8 In one embodiment, the two wiring structures 22 are arranged along the axial direction of the basin frame 1.

[0058] With this arrangement, when the basin frame assembly 10 is specifically applied to the speaker 100, the lead wire 201 of the voice coil 20 is led out from the end of the voice coil 20 close to the diaphragm and connected to the wiring structure 22 of the terminal 2 close to the diaphragm, and the external wire 30 of the speaker 100 is connected to the wiring structure 22 of the terminal 2 away from the diaphragm. The external wire 30 of the speaker 100 can be extended outward from the rear side of the speaker 100 to facilitate wiring.
