[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] The terms "first," "second," "third," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0023] The following detailed descriptions will be provided through specific embodiments.

[0024] This application provides a loudspeaker including a surround with ribs. By providing ribs on the surround, this loudspeaker can effectively improve the mid-frequency dip problem.

[0025] refer to Figure 1 and Figure 2 This illustrates the specific structure of a loudspeaker. The following section uses... Figure 1 and Figure 2 Taking the speaker shown as an example, the technical solution of the embodiment of this application will be described in detail.

[0026] like Figure 1 and Figure 2 As shown, the loudspeaker includes a magnetic circuit system and a vibration system. The magnetic circuit system can consist of a T-iron 1, a magnet 2, a washer 3, and a frame 4. The washer 3 is positioned above the magnet 2, the T-iron 1 is positioned below the magnet 2, and the frame 4 supports and secures the T-iron 1, magnet 2, washer 3, and other components. The vibration system can consist of a positioning support 5, a diaphragm 6, a voice coil 7, and a dust cap 8. The diaphragm 6 is the vibrating unit, pushing air to produce sound when vibrating. The voice coil 7 is located within the magnetic field formed by the magnetic circuit system and is connected to the diaphragm 6, causing the diaphragm 6 to vibrate. The frequency response curve of the loudspeaker during vibration is mainly affected by the diaphragm 6. The positioning support 5 connects the voice coil 7 and the frame 4, providing positioning and support. The dust cap 8 is positioned above the diaphragm 6, primarily for dust protection.

[0027] The drum 6 includes a cone 9 and a folded ring 10. The cone 9 mainly functions to vibrate and produce sound, with the voice coil 7 connected to its inner side and the folded ring 10 connected to its outer side. The inner side of the folded ring 10 is connected to the cone 9, and the outer side is connected to the frame 4.

[0028] When the loudspeaker is operating, the vibration of the surround 10 cannot be perfectly synchronized with that of the cone 9. It has its own resonance characteristics and may be exactly out of phase with the cone's movement at a certain frequency. This results in a phenomenon known as surround anti-resonance, which affects the movement of the cone 9 and ultimately produces a "mid-frequency trough" in the sound output. To alleviate this problem, the surround 10 should ideally be able to dissipate the energy of this vibration itself, that is, it should have good internal damping.

[0029] In this embodiment, at least one rib structure 11 is provided on the folded ring 10 to improve the internal damping of the folded ring 10, thereby effectively improving the mid-frequency valley problem.

[0030] In some alternative embodiments, the surround 10 has a first surface 101 facing the central axis of the speaker, and the rib structure 11 can be disposed on the first surface 101. This more effectively increases internal damping, reduces sound waves radiated by the surround 10, and thus contributes to the improvement of the mid-frequency valley.

[0031] In some alternative embodiments, the rib structure 11 extends on the first surface 101 in a direction away from the central axis of the speaker. Furthermore, the rib structure 11 forms an angle (acute angle) with the central axis of the speaker. Furthermore, in the transverse cross-section of the speaker, the rib structure 11 forms an angle (acute angle) with the radial direction. This improves the internal damping of the surround 10, reduces the sound waves radiated by the surround 10, and is beneficial for improving the mid-frequency valley.

[0032] In some alternative embodiments, the cross-sectional shape of the rib structure 11 is circular. That is, the rib structure 11 can be in the shape of a circular strip and adhered to the fold ring 10. This facilitates processing and manufacturing.

[0033] In some alternative embodiments, multiple rib structures 11 are provided, which are circumferentially uniformly or non-uniformly distributed in the top view direction.

[0034] In some alternative embodiments, the folded ring 10 includes, from the inside out, an inner ring pressing edge 102, a damping part 103, a folded ring part 104, and an outer ring snap-fit ​​part 105.

[0035] The damping section 103 is used to increase the internal damping of the folded ring 10. The rib structure 11 can be disposed on the outer surface of the damping section 103 to cooperate with the damping section 103, thereby better increasing the internal damping and improving the mid-frequency valley problem.

[0036] The first surface 101 described above may include the outer surface of the damping portion 103 and the side surface of the folded ring portion 104 facing the central axis.

[0037] In some alternative embodiments, the cross-sectional shape of the folded ring portion 104 is a semi-circular ring.

[0038] Optionally, the thickness of the damping part 103 is greater than that of the inner ring pressing edge 102 and greater than that of the folded ring part 104, so as to maximize the internal damping of the folded ring 10.

[0039] In some alternative embodiments, the cross-sectional shape of the damping part 103 is close to a quarter circle, and the rib structure 11 is disposed on its arc surface. This type of damping part 103 can better reduce the sound waves radiated by the folded ring 10, which is beneficial to improving the mid-frequency valley problem.

[0040] The above, combined with Figure 1 and Figure 2 The speaker structure shown provides a detailed description of the solution in this application embodiment. However, it should be noted that... Figure 1 and Figure 2 The speaker structure shown is merely an example and does not limit the technical solution of this application. In fact, any speaker with a surround can be applied to the technical solution of the embodiments of this application.

[0041] The loudspeaker of this embodiment reduces the speaker's breakup vibration by incorporating a rib structure on the surround, thereby effectively improving the mid-frequency dip problem, reducing nonlinear distortion (by more than 15%), and improving the transition of high frequencies and the performance of vocals. Furthermore, the loudspeaker of this embodiment also has advantages such as good product consistency, simple manufacturing process, labor savings, and low cost.

[0042] The technical solution of this application has been described in detail above through specific embodiments. In the above embodiments, the descriptions of each embodiment have their own emphasis, and for parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0043] It should be understood that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; however, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and protection scope of the technical solutions of the embodiments of this application.
