[0047] The present invention provides a vibration plate 10 which can be applied to a loudspeaker to facilitate the extension of the acoustic high-frequency performance of the loudspeaker.

[0048] The specific structure of the vibration plate 10 of the present invention is described below, and the vibration plate 10 is placed horizontally as an example for introduction:

[0049] like Figures 1 to 4 As shown, in an embodiment of the vibration plate 10 of the present invention, the vibration plate 10 includes:

[0050] A mounting portion 11, the mounting portion 11 is disposed around the central axis of the vibration plate 10, and the mounting portion 11 is disposed in a flared shape;

[0051] A vibration part 13, wherein the vibration part 13 is disposed around the central axis of the vibration plate 10 and connected to the top of the mounting part 11, the vibration part 13 is disposed in a flared shape, and the inclination angle thereof is greater than the inclination angle of the mounting part 11; and

[0052] The connecting portion 15 is disposed around the central axis of the vibration plate 10 and connected to the top of the vibration portion 13 . The connecting portion 15 is disposed in a flared shape and has an inclination angle smaller than that of the vibration portion 13 .

[0053] In this embodiment, the mounting portion 11 is composed of a straight side wall inclined outward, and the straight side wall is defined as the first side wall; the vibration portion 13 is composed of a straight side wall inclined outward, and the straight side wall is defined as the second side wall; the connecting portion 15 is composed of a straight side wall inclined outward, and the straight side wall is defined as the third side wall, then: the inclination angle of the first side wall is smaller than the inclination angle of the second side wall, that is, the angle between the first side wall and the central axis of the vibration plate 10 is larger than the angle between the second side wall and the central axis of the vibration plate 10, that is, the second side wall is steeper than the first side wall; at the same time, the inclination angle of the second side wall is larger than the inclination angle of the third side wall, that is, the angle between the second side wall and the central axis of the vibration plate 10 is smaller than the angle between the third side wall and the central axis of the vibration plate 10, that is, the third side wall is flatter than the second side wall.

[0054] It can be understood that the mounting portion 11 can be used to connect with the voice coil bracket of the speaker, and the connecting portion 15 can be used to connect with the folding ring 30, and then connected with the frame of the speaker through the folding ring 30. At this time, under the premise of a certain height of the speaker, since the entire side wall of the vibration plate 10 of the present invention is in a twice-bent setting form, the vibration portion 13 between the mounting portion 11 and the connecting portion 15 can present a more "steeper" structural feature. Compared with the traditional linear vibration plate 10, the angle between the vibration portion 13 and the central axis of the vibration plate 10 in the technical solution of the present invention is smaller and more "steeper". Therefore, it can be beneficial to extend the acoustic high-frequency performance of the speaker and improve the acoustic performance of the speaker.

[0055] Furthermore, since the entire side wall of the vibration plate 10 of the present invention is bent twice, the mounting portion 11 and the connecting portion 15 both present a more "gentle" structural feature compared to the traditional linear vibration plate 10. The "gentle" setting of the mounting portion 11 can be beneficial to the coating and adhesion of glue when the mounting portion 11 is connected to the voice coil bracket of the loudspeaker, thereby facilitating the curing and bonding of the glue, achieving a more stable connection between the two, and thus improving the structural stability and reliability of the loudspeaker; and the "gentle" setting of the connecting portion 15 can be beneficial to the connection between the connecting portion 15 and the folding ring 30, reducing the deformation of the inner edge of the folding ring 30 toward the bottom of the vibration plate 10, which is beneficial to ensuring the function of the folding ring 30, and thus is beneficial to obtaining a loudspeaker with higher stability and reliability; at the same time, the "gentle" setting of the connecting portion 15 can also be beneficial to the coating and adhesion of glue when the connecting portion 15 is connected to the folding ring 30, thereby facilitating the curing and bonding of the glue, achieving a more stable connection between the two, and thus improving the structural stability and reliability of the loudspeaker.

[0056] like Figure 1 and Figure 2 As shown, in an embodiment of the vibration plate 10 of the present invention, the inner surface of the vibration plate 10 is provided with a first thickened portion 17 at the connection between the mounting portion 11 and the vibration portion 13 .

[0057] In this embodiment, the mounting portion 11, the vibration portion 13 and the connection portion 15 are enclosed together to form a cavity 10a, and the inner surface of the vibration plate 10 is the surface of the vibration plate 10 facing the cavity 10a. At this time, the first thickened portion 17 is only provided at the connection between the mounting portion 11 and the vibration portion 13 on the inner surface of the vibration plate 10, thereby realizing the local thickening of the vibration plate 10. In this way, the strength of the vibration plate 10 is enhanced, the structural stability of the vibration plate 10 is improved, and the reliability of the vibration plate 10 is improved, while the problem of a significant increase in the weight of the vibration plate 10 caused by the traditional overall thickening method is avoided, thereby ensuring the vibration efficiency of the vibration plate 10.

[0058] Furthermore, the inner surface of the first thickened portion 17 smoothly transitions with the inner surface of the mounting portion 11, and the inner surface of the first thickened portion 17 smoothly transitions with the inner surface of the vibration portion 13. In this way, under the premise that the mass (or volume) of the first thickened portion 17 is constant, the lengths of the "two wings" of the first thickened portion 17 can be expanded, that is, the width of the first thickened portion 17 is increased, so that the "two wings" of the first thickened portion 17 can cover more of the inner surface of the mounting portion 11 and the inner surface of the vibration portion 13, thereby enhancing the reinforcing effect of the first thickened portion 17 on the connection between the mounting portion 11 and the vibration portion 13. In addition, the setting of smooth transition can also improve the smoothness of the inner surface of the vibration plate 10, which is conducive to the transmission of sound waves outward.

[0059] like Figure 1 and Figure 2 As shown, in an embodiment of the vibration plate 10 of the present invention, the first thickened portion 17 is an integral structure integrally formed with the mounting portion 11 and the vibration portion 13. Specifically, slurry molding or injection molding can be adopted. In this way, the difficulty of setting the first thickened portion 17 is greatly reduced, the production process of the vibration plate 10 is simplified, and the production efficiency of the vibration plate 10 and the speaker is improved. In addition, the integral structure is more conducive to controlling the center of gravity of the vibration plate 10, avoiding the polarization problem caused by the center of gravity offset, so that the vibration plate 10 has more excellent stability and reliability, thereby further improving the acoustic performance of the speaker.

[0060] like Figure 1 and Figure 3 As shown, in an embodiment of the vibration plate 10 of the present invention, the outer surface of the vibration plate 10 is provided with a second thickened portion 19 at the connection between the connection portion 15 and the vibration portion 13 .

[0061] In this embodiment, the mounting portion 11, the vibration portion 13 and the connection portion 15 are enclosed together to form a cavity 10a, and the outer surface of the vibration plate 10 is the surface of the vibration plate 10 that faces away from the cavity 10a. At this time, the second thickened portion 19 is only provided at the connection between the connection portion 15 and the vibration portion 13 on the outer surface of the vibration plate 10, thereby achieving partial thickening of the vibration plate 10. In this way, the strength of the vibration plate 10 is enhanced, the structural stability of the vibration plate 10 is improved, and the reliability of the vibration plate 10 is improved, while the problem of a significant increase in the weight of the vibration plate 10 caused by the traditional overall thickening method is avoided, thereby ensuring the vibration efficiency of the vibration plate 10.

[0062] Furthermore, the outer surface of the second thickened portion 19 smoothly transitions with the outer surface of the connecting portion 15, and the outer surface of the second thickened portion 19 smoothly transitions with the outer surface of the vibrating portion 13. In this way, under the premise that the mass (or volume) of the second thickened portion 19 is constant, the lengths of the "two wings" of the second thickened portion 19 can be expanded, that is, the width of the second thickened portion 19 is increased, so that the "two wings" of the second thickened portion 19 can cover more outer surfaces of the connecting portion 15 and more outer surfaces of the vibrating portion 13, thereby enhancing the reinforcing effect of the second thickened portion 19 on the connection between the connecting portion 15 and the vibrating portion 13.

[0063] like Figure 1 and Figure 3As shown, in an embodiment of the vibration plate 10 of the present invention, the second thickened portion 19 is an integral structure integrally formed with the connecting portion 15 and the vibration portion 13. Specifically, slurry molding or injection molding can be adopted. In this way, the difficulty of setting the second thickened portion 19 is greatly reduced, the production process of the vibration plate 10 is simplified, and the production efficiency of the vibration plate 10 and the speaker is improved. In addition, the integral structure is more conducive to controlling the center of gravity of the vibration plate 10, avoiding the polarization problem caused by the center of gravity offset, so that the vibration plate 10 has more excellent stability and reliability, thereby further improving the acoustic performance of the speaker.

[0064] like Figures 1 to 4 As shown, the present invention further proposes a composite basin structure 100, which includes the vibration plate 10 as described above, and the specific structure of the vibration plate 10 refers to the above embodiment. Since the composite basin structure 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by all the technical solutions of all the above embodiments, which will not be described one by one here.

[0065] Among them, Figure 1 and Figure 3 As shown, the inner edge of the folding ring 30 is disposed around the circumference of the connecting portion 15 of the vibration plate 10 and is connected to the outer edge of the connecting portion 15;

[0066] The folding ring 30 includes an inner edge portion 31, a bending portion 33 and an outer edge portion 35. The inner edge portion 31, the bending portion 33 and the outer edge portion 35 are sequentially arranged from the center of the folding ring 30 outwards, and the inner edge portion 31 is arranged in contact with the inner surface of the connecting portion 15.

[0067] A limiting portion 37 is protruding from the surface of the folding ring 30 that is away from the front of the composite basin structure 100 at the connection between the bending portion 33 and the inner edge portion 31 , and the outer edge of the connecting portion 15 abuts against the limiting portion 37 .

[0068] It can be understood that the limiting function of the limiting portion 37 can further enhance the connection stability between the folding ring 30 and the vibration plate 10, improve the reliability of the composite basin structure 100, and thus ensure the excellent acoustic performance of the speaker.

[0069] The present invention further provides a loudspeaker, which includes the composite basin structure 100 as described above. The specific structure of the composite basin structure 100 refers to the above-mentioned embodiment. Since the present loudspeaker adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by all the technical solutions of all the above-mentioned embodiments, which will not be described one by one here.

Since the acoustic device adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by all the technical solutions of all the above-mentioned embodiments, which will not be described one by one here.

[0071] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
