[0033] like Figure 1-4 As shown, the utility model provides a lead guiding structure, including a wire pressing plate 210 and an elastic member 220 .

[0034] The wire pressing plate 210 is disposed in the housing 100, and is slidably connected to the housing 100. The wire pressing plate 210 can perform reciprocating linear motion between a first position and a second position in a direction close to or away from the inner wall of the housing 100. When the wire pressing plate 210 is in the first position, the wire pressing plate 210 is far from the inner wall of the housing 100, so that the lead 400 is placed between the wire pressing plate 210 and the inner wall of the housing 100; when the wire pressing plate 210 is in the second position, the wire pressing plate 210 is close to the inner wall of the housing 100, so that the lead 400 is pressed tightly between the wire pressing plate 210 and the inner wall of the housing 100.

[0035] The elastic member 220 is disposed in the housing 100, and the two ends of the elastic member 220 are respectively connected to the wire pressing plate 210 and the housing 100, and in a natural state, the elastic member 220 has a tendency to move the wire pressing plate 210 toward the inner wall of the housing 100. Specifically, the elastic member 220 can be any component with elastic force, and in this embodiment, the elastic member 220 is a spring.

[0036] Specifically, when installing the lead 400, first place the wire pressing plate 210 in the first position. After the lead 400 is placed between the wire pressing plate 210 and the inner wall of the shell 100, place the wire pressing plate 210 in the second position to press the lead 400 between the wire pressing plate 210 and the inner wall of the shell 100. Under the action of the elastic force of the elastic member 220, the purpose of keeping the lead 400 pressed between the wire pressing plate 210 and the inner wall of the shell 100 is achieved.

[0037] The lead guiding structure provided in this embodiment, by setting a wire pressing plate 210 and an elastic member 220, utilizes the elastic force of the elastic member 220 to press the lead 400 between the wire pressing plate 210 and the inner wall of the shell 100, so that when the speaker is producing sound, the lead 400 will not collide with the shell 100, thereby achieving the purpose of increasing the service life of the lead 400 and avoiding abnormal noise.

[0038] Preferably, a flexible pad 230 is provided on one side of the wire pressing plate 210 facing the inner wall of the housing 100 to prevent the wire pressing plate 210 from crushing the lead wire 400. The flexible pad 230 may be a flexible pad made of silica gel, rubber or the like.

[0039] In one embodiment, a locking assembly is further included, and the locking assembly has a locked state and an unlocked state. When the locking assembly is in the locked state, the locking assembly can lock the wire pressing plate 210 in the first position. When the locking assembly is in the unlocked state, the locking assembly cannot lock the wire pressing plate 210.

[0040] Specifically, when in use, the wire pressing plate 210 is first placed in the first position, and the locking assembly is placed in a locked state, thereby locking the wire pressing plate 210 in the first position, and then facilitating the placement of the lead 400 between the wire pressing plate 210 and the inner wall of the housing 100.

[0041] After the lead 400 is placed, the locking assembly is placed in the unlocked state, and under the elastic force of the elastic member 220, the wire pressing plate 210 is moved from the first position to the second position, thereby pressing the lead 400 between the wire pressing plate 210 and the housing 100.

[0042] The lead wire guiding structure provided in this embodiment achieves the purpose of facilitating the placement of the lead wire 400 between the wire pressing plate 210 and the inner wall of the housing 100 by providing a locking assembly.

[0043] In one embodiment, the locking assembly includes an elastic arm 310 and a limiting plate 320 .

[0044] The first end of the elastic arm 310 is fixedly connected to the wire pressing plate 210, and the second end extends away from the inner wall of the housing 100. The limiting plate 320 is disposed in the housing 100, and a limiting hole 321 is provided on the limiting plate 320 for the second end of the elastic arm 310 to pass through. A limiting protrusion 311 is provided at the second end of the elastic wall.

[0045] During use, when the wire pressing plate 210 is placed in the first position, the second end of the elastic arm 310 passes through the limiting hole 321. Under the action of the limiting protrusion 311, the elastic arm 310 cannot be pulled out of the limiting hole 321 under the action of the elastic force of the elastic member 220, thereby achieving the purpose of locking the limiting plate 320 in the first position.

[0046] When it is necessary to release the lock of the wire pressing plate 210, the elastic arm 310 is pressed, so that the limiting protrusion 311 is separated from the side wall of the limiting hole 321, so that the elastic arm 310 can pass through the limiting hole 321, thereby achieving the purpose of releasing the lock of the wire pressing plate 210. Under the action of the elastic force of the elastic member 220, the elastic arm 310 passes through the limiting hole 321, thereby achieving the purpose of driving the wire pressing plate 210 to the second position.

[0047] The locking assembly of the lead wire guiding structure provided in this embodiment has a simple structure, a reasonable design, and is easy to operate.

[0048] Preferably, a guide slope 301 is provided on the second end of the elastic arm 310 and / or the side of the limiting plate 320 facing the wire pressing plate 210, so that the elastic arm 310 can easily pass through the limiting hole 321 when the wire pressing plate 210 moves from the second position to the first position.

[0049] Preferably, the elastic arm 310 and the wire pressing plate 210 are integrally formed.

[0050] Preferably, the limiting plate 320 and the housing 100 are integrally formed.

[0051] In one embodiment, the utility model further provides a speaker, comprising the lead guiding structure described in any of the above embodiments.

However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
