[0039] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present disclosure.

[0040] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0041] Combined Figure 1 and Figure 2 As shown, the embodiment of the present disclosure provides an anti-distortion speaker, which includes a washer cover 1, a yoke housing 2, a magnet 3, a diaphragm 4, a dust cap 5, and a voice coil 6; a magnet 3 is arranged inside the yoke housing 2, and a sound cavity is formed at an interval from the magnet 3; the washer cover 1 is covered on the top side of the yoke housing 2 and is provided with an opening for avoiding the magnet 3; the dust cap 5 is covered on the opening and is connected to the side of the washer cover 1 facing away from the magnet 3 through the diaphragm 4; the voice coil 6 is sleeved at an interval on the outer peripheral part of the magnet 3, and one end is connected to the dust cap 5; wherein, the dust cap 5, the washer cover 1, and the yoke housing 2 jointly form the outer housing of the anti-distortion speaker.

[0042] Compared with the speakers with traditional structures in the prior art, for the anti-distortion speaker provided by the embodiment of the present disclosure, first, the sound cavity space is separately arranged inside the yoke housing 2, and the formed sound cavity space can be simpler and larger. Only the magnet 3 is arranged in the sound cavity space, avoiding the extrusion and occupation of the sound cavity space by other components. Moreover, the single structure of the yoke housing 2 is equivalent to the "speaker lower cover + fixing seat" in the traditional speaker structure. While realizing the magnetic conduction function, it also serves as the function of the "speaker lower cover", achieving the effect of multiple functions of a single component and improving the anti-distortion performance of the anti-distortion speaker.

[0043] Furthermore, the washer cover 1 is directly covered on the top side of the yoke housing 2, and the washer cover 1 is also provided with an opening for avoiding the magnet 3. The dust cap 5 is covered on the opening and is connected to the side of the washer cover 1 facing away from the magnet 3 through the diaphragm 4; the voice coil 6 is sleeved at an interval on the outer peripheral part of the magnet 3, and one end is connected to the dust cap 5. In this way, the single structure of the washer cover 1 is equivalent to the "speaker upper cover + frame" in the traditional speaker structure. While realizing the magnetic conduction function, it also serves as the function of the "speaker upper cover", also achieving the effect of multiple functions of one component.

[0044] In addition, the diaphragm paper 5, the washer cover plate 1, and the yoke seat shell 2 jointly form the outer shell of the anti-distortion speaker. The internal space formed by the three is more spacious and abundant. Under the same acoustic performance, the required volume and height can be reduced by about 20% compared with the traditional speaker structure. In addition, through the single-cavity structure of the yoke seat shell 2, the heat dissipation effect of the anti-distortion speaker can also be improved.

[0045] In summary, the anti-distortion speaker provided by the embodiments of the present disclosure has the beneficial effects of single-component multi-function, simplified speaker structure layout, improved effective utilization rate of the sound cavity space, improved anti-distortion performance, and improved heat dissipation performance.

[0046] In an implementable manner, the top of the yoke seat shell 2 has a mounting opening and a mounting edge 21 located at the periphery of the mounting opening; the washer cover plate 1 is covered and installed in the mounting opening and is wrapped and fixed by the mounting edge 21.

[0047] Specifically, in combination with Figure 1 and Figure 2 For further detailed description, the top of the yoke seat shell 2 has a mounting opening, and a mounting edge 21 is also provided at the periphery of the mounting opening. The mounting edge 21 can be specifically but not limited to being set as an annular edge. In this way, when the washer cover plate 1 is covered and installed in the mounting opening, the periphery of the washer cover plate 1 can be surrounded and fixed by the mounting edge 21, and the washer cover plate 1 and the mounting edge 21 can be specifically set to be assembled and connected in an interference fit or a transition fit manner.

[0048] The above specific setting method of the mounting edge 21 has the beneficial effects of simple structure and stable limit installation of the washer cover plate 1.

[0049] In an implementable manner, a frame edge 11 is also convexly provided on the side of the washer cover plate 1 facing the yoke seat shell 2; an installation gap is formed between the inner edge wall of the frame edge 11 and the outer peripheral wall of the magnet 3; the voice coil 6 is located in the installation gap.

[0050] Specifically, in combination with Figure 1 and Figure 2 For further detailed description, a frame edge 11 is also convexly provided on the side of the washer cover plate 1 facing the yoke seat shell 2. The frame edge 11 can also be specifically set as an annular edge, and an installation gap is formed between the inner edge wall of the frame edge 11 and the outer peripheral wall of the magnet 3; the voice coil 6 is located in the installation gap. In this way, when guiding the magnetic field of the magnet 3, the magnetic induction lines can emit from one end of the magnet 3, pass through the voice coil 6, and converge more fully into the washer cover plate 1 and the yoke seat shell 2 through the frame edge 11.

[0051] The above specific setting method of the frame edge 11 has the beneficial effects of simple structure and full convergence and magnetic field guiding of the magnetic induction lines of the magnet 3.

[0052] In an implementable embodiment, the frame edge 11 includes an integrally connected connecting edge and an extending edge; the connecting edge is vertically connected to the washer cover plate 1, and the extending edge is perpendicular to the connecting edge and extends toward the outer peripheral wall of the magnet 3.

[0053] Specifically, in combination with Figure 1 a further detailed description, both the connecting edge and the extending edge in the frame edge 11 can be specifically set to form a stepped edge with an "L" cross-section. In this way, through the extending edge, the actual distance between the frame edge 11 and the voice coil 6 can be reduced, which is more conducive to converging the magnetic induction lines of the magnet 3; the connecting edge can make the overall frame edge 11 concave. On the one hand, it can make the extending edge correspond to the magnet 3 in the horizontal direction, and on the other hand, it can also reserve a concave space for avoiding the installation of the diaphragm 5.

[0054] In an implementable embodiment, the yoke housing 2 includes a bottom wall 22 and a circumferential wall 23; the circumferential wall 23 is integrally and vertically connected to the edge of the bottom wall 22; the mounting edge 21 is integrally connected to the outer wall at the top of the circumferential wall 23.

[0055] Specifically, in combination with Figure 1 and Figure 2 a further detailed description, the yoke housing 2 is specifically set to be a bottom wall 22 and a circumferential wall 23 that are integrally and vertically connected, and the mounting edge 21 is integrally connected to the outer wall at the top of the circumferential wall 23. Of course, all three of the mounting edge 21, the bottom wall 22, and the circumferential wall 23 are made of a magnetically conductive material. In this way, when guiding the magnetic field of the magnet 3, the magnetic induction lines coming from the washer cover plate 1 can be further fully conducted by the yoke housing 2 to the other end of the magnet 3.

[0056] The above specific setting method of the yoke housing 2 has the beneficial effects of simple structure and being able to fully guide the magnetic field of the magnet 3.

[0057] In an implementable embodiment, the mounting edge 21 and the outer wall at the top of the circumferential wall 23 form a stepped flared edge; the bottom wall 22 and the circumferential wall 23 form a mounting cavity, and the magnet 3 is displaced at the central part of the mounting cavity.

[0058] Specifically, in combination with Figure 1 a further detailed description, the mounting edge 21 and the outer wall at the top of the circumferential wall 23 are specifically set to form a stepped flared edge. In this way, the washer cover plate 1 can be plugged and limited within the mounting edge 21 and be supported by the top of the circumferential wall 23, fully ensuring the installation stability and compactness of the washer cover plate 1 and the yoke housing 2.

[0059] In an implementable embodiment, the washer cover plate 1 is embedded and installed in the mounting opening of the yoke housing 2 and is flush with the top of the yoke housing 2.

[0060] Specifically, in combination with Figure 1For a further detailed description, the washer cover plate 1 is flush-mounted on the mounting opening of the yoke housing 2, which can improve the mounting compactness of the washer cover plate 1 and the yoke housing 2. Moreover, when guiding the magnetic field of the magnet 3, the flush joint between the washer cover plate 1 and the yoke housing 2 is more convenient for guiding the magnetic induction lines.

[0061] In an implementable embodiment, one side of the diaphragm 4 is connected to the washer cover plate 1, and the other side is connected to the dust cap 5; and the corresponding part of the diaphragm 4 between the washer cover plate 1 and the dust cap 5 further has a protruding elastic part 41.

[0062] Specifically, in combination with Figure 1 For a further detailed description, one side of the diaphragm 4 is connected to the washer cover plate 1, the other side is connected to the dust cap 5, and the corresponding part of the diaphragm 4 between the washer cover plate 1 and the dust cap 5 further has a protruding elastic part 41. In this way, when the voice coil 6 makes a small up-and-down movement relative to the magnet 3, the dust cap 5 can move accordingly. At this time, the elastic part 41 can cooperate with the movement of the dust cap 5 through elastic deformation.

[0063] In an implementable embodiment, a through hollow structure is also provided in the elastic part 41.

[0064] Specifically, in combination with Figure 2 For a further detailed description, at this time, the diaphragm 4 can be specifically set as a square ring shape, the hollow structure can be specifically arranged at the corners of the diaphragm 4, and the hollow structure can be specifically set as a crescent-shaped hollow opening. In this way, the hollow structure weakens the structural strength of the diaphragm 4 at the corners to a certain extent, thus making it more conducive to the diaphragm 4 to generate elastic deformation to cooperate with the movement of the dust cap 5.

[0065] In an implementable embodiment, a washer 31 is further provided on the side of the magnet 3 facing the dust cap 5; the magnetic circuit of the magnet 3 passes through one end magnetic pole of itself, the washer 31, the voice coil 6, the washer cover plate 1, and the yoke housing 2 and leads to the other end magnetic pole of itself.

[0066] Specifically, in combination with Figure 1 For a further detailed description, a washer 31 is further provided on the side of the magnet 3 facing the dust cap 5. In this way, the magnetic circuit of the magnet 3 can sequentially enter the washer 31, the voice coil 6, the washer cover plate 1, and the yoke housing 2 from one end magnetic pole and return to the other end magnetic pole of itself, efficiently realizing the convergence and closed-loop of the magnetic circuit.

[0067] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present disclosure, "a plurality" means two or more unless otherwise specifically defined.

[0068] As described above, it is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered within the protection scope of the present disclosure.
