The integrated design of the elastic wave assembly reduces sound distortion caused by the assembly of multiple components and improves the sound quality performance of the speaker. The elastic wave assembly can be assembled at one time, which greatly improves the efficiency of the production line and reduces production costs compared to the traditional design that requires the separate assembly of multiple elastic waves.

Description

Technical Field

[0001] The present invention relates to the technical field of loudspeakers, and in particular to a miniature loudspeaker bracket with a split structure. Background Art

[0002] Dynamic microspeakers are widely used in modern audio equipment due to their excellent sound quality and miniaturization. However, with the increasing demand for sound quality and performance, the speaker's vibration system must still maintain linear displacement vibration under large amplitude operating conditions, which places higher demands on speaker design.

[0003] To achieve this, a speaker's vibration system often incorporates a spring (also known as an auxiliary diaphragm). This spring's function is to enhance the linear response of the vibration system and improve sound quality. However, the design and assembly of springs present a number of challenges in actual production.

[0004] First, the back of the speaker stand must be designed with a magnetic circuit system and ventilation holes. This requirement prevents the back of the stand from being a single, flat surface. Consequently, interference between the damper and the stand often occurs, making a single, complete assembly impossible. To circumvent this interference, existing solutions divide the damper into multiple sections (usually four or two) and assemble them individually on the speaker stand. This grouped assembly method not only increases the complexity of the assembly process but also reduces production efficiency.

[0005] Secondly, the elastic wave is typically made of a soft film, further increasing the difficulty of assembly. When assembled with the bracket, strict requirements for flatness, symmetry, and concentricity are required. Poor assembly consistency of multiple elastic waves (such as height differences, poor flatness, or poor concentricity) will directly affect the stability of the vibration system. In particular, during vibration displacement, the system may experience wobbling vibrations, preventing the voice coil from fully moving within the linear magnetic gap. This wobbling vibration not only causes friction between the inner side of the voice coil and the magnetic pole piece, and between the outer side of the voice coil and the magnetic bowl or outer magnetic plate, but can also generate mechanical noise, seriously affecting the speaker's sound quality, increasing quality risks, and reducing production yields.

[0006] In summary, current speaker design and assembly methods face problems with component interference and assembly consistency. These problems not only affect sound quality performance but also increase the complexity of the production process. Therefore, there is an urgent need to develop a new solution to improve speaker performance and manufacturing efficiency. Summary of the Invention

[0030] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The principles and features of the present invention are described below in conjunction with the drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] The terms "including" and other similar expressions in the specification or claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions, such as a process, method or system, or device that includes a series of steps or units is not limited to the listed steps or units.

[0032] Example 1: Figure 1-4 As shown, a split-structure micro speaker bracket specifically includes:

[0033] Upper bracket 100; the outer side of the upper bracket 100 is used to connect with the diaphragm 111,

[0034] The lower bracket 101 has a plurality of grooves on its outer surface for aligning with the magnetic circuit assembly 112;

[0035] The damper assembly 102 includes a middle ring 103 and a damper body 104 connected to the middle ring 103 . The middle ring 103 is made of a highly elastic film material to ensure good linear displacement vibration under large amplitude.

[0036] To address the issue of traditional dampers being unable to be assembled in one piece, the damper body 104 is integrally formed on the center ring 103. The damper body 104 and center ring 103 are designed as a single, integrated structure, eliminating the need for multiple components. This simplifies assembly and improves consistency.

[0037] The inner side of the lower bracket 101 has a flat surface 105 aligned with the middle ring 103;

[0038] The upper bracket 100, the elastic wave assembly 102 and the lower bracket 101 are aligned and matched in sequence to fix the elastic wave assembly 102 between the upper bracket 100 and the lower bracket 101, and an avoidance space 106 is provided on the upper bracket 100 and the lower bracket 101 corresponding to the elastic wave body 104 to ensure that the elastic wave body 104 does not contact the bracket during vibration.

[0039] In a specific solution, the voice coil 113 is disposed in the lower bracket 101 , and the elastic wave body 104 is further connected to the voice coil 113 .

[0040] The upper bracket 100 is provided with a pressing surface 110 that aligns with the plane 105 of the lower bracket 101. The middle ring 103 is pressed and fixed by the pressing surface 110 and the plane 105. The pressing surface 110 is provided on the inner side of the upper bracket 100, and its specific position corresponds to the plane 105 on the lower bracket 101.

[0041] During the specific assembly process, first place the lower bracket 101 on a flat workbench and fix the magnetic circuit assembly 112 in its groove;

[0042] Next, align the center ring 103 of the damper assembly 102 with the flat surface 105 of the lower bracket 101 to ensure they fit tightly together.

[0043] Then, the upper bracket 100 is aligned with the damper assembly 102 so as to ensure a good alignment with the lower bracket 101 and the damper assembly 102 .

[0044] Then, the upper bracket 100 and the lower bracket 101 are fixed together by screws or other fixing means to ensure that the damper assembly 102 is firmly clamped therebetween.

[0045] Finally, check the flatness and symmetry of the entire assembly to ensure assembly consistency.

[0046] By designing the damper assembly as an integrated structure, rather than dividing it into multiple parts, the complexity of the assembly process is greatly reduced, while avoiding the problems of height difference, flatness and poor concentricity caused by multiple assemblies in traditional methods.

[0047] In one possible embodiment, the center coil 103 is in the shape of a rounded rectangle, with a damper body 104 disposed at each of its four corners. A placement space for accommodating the voice coil 113 is formed between the four damper bodies 104 in the circumferential direction of the center coil 103. The four damper bodies 104 are respectively connected to the four corners of the voice coil 113 to fix it in the center position.

[0048] In another possible embodiment, a damper body 104 is provided on two opposite sides of the center coil 103. A placement space for accommodating the voice coil 113 is formed between the damper bodies 104 on both sides. The two damper bodies 104 are respectively used to connect to two opposite sides of the voice coil 113 to fix it in the center position.

[0049] The current industry requires the assembly of four or two separate dampers, but this solution only requires the assembly of a single, integrated damper. By optimizing this integrated damper, its outer ring plane aligns with the outer ring plane of the lower bracket, eliminating interference from surrounding structures. This makes assembly smoothness, symmetry, and concentricity much easier to achieve. This avoids the problem of poor consistency caused by assembling four or two separate dampers, which can cause the vibration system to vibrate during displacement. This prevents the voice coil from fully linearly moving within the magnetic gap, generating wobble. During this wobble, the inner side of the voice coil rubs against the pole piece and the outer side of the voice coil rubs against the bowl, resulting in mechanical noise and other quality risks.

[0050] It is optimized into a whole elastic wave, and the outer ring plane of the elastic wave is assembled with the outer ring plane of the lower bracket, which greatly optimizes the flatness, symmetry and concentricity of the assembly of the elastic wave and the lower bracket, and improves the production yield of the speaker.

[0051] The industry currently requires the assembly of 4 or 2 dampers separately. This solution only requires the assembly of one entire damper, thereby improving production and assembly efficiency.

[0052] Example 2: Figure 1 As shown, in order to improve the alignment accuracy between the upper bracket 100 and the lower bracket 101 , a positioning structure 107 is provided between the upper bracket 100 and the lower bracket 101 , and the upper bracket 100 and the lower bracket 101 are aligned through the positioning structure 107 .

[0053] The positioning structure 107 includes a plurality of positioning grooves 108 that cooperate in pairs and positioning blocks 109 that align with the positioning grooves 108 . The plurality of positioning grooves 108 and positioning blocks 109 that are arranged in pairs are distributed on opposite sides of the upper bracket 100 and the lower bracket 101 .

[0054] Specifically, the positioning groove 108 may be provided on the upper bracket 100 , and the positioning block 109 may be provided on the lower bracket 101 ; or, the positioning block 109 may be provided on the upper bracket 100 , and the positioning groove 108 may be provided on the lower bracket 101 .

[0055] For example, positioning grooves 108 are designed along the edge of the upper bracket 100 and appropriately distributed to ensure multiple positioning points. Positioning blocks 109 correspond to the positioning grooves 108 and are provided on the lower bracket 101. The positioning grooves 108 on the upper bracket 100 mate with the positioning blocks 109 on the lower bracket 101. During assembly, the positioning blocks are inserted into the corresponding grooves to ensure accurate alignment between the two.

[0056] Example 3: Figure 5-6 As shown, in order to further optimize the positioning effect, a V-shaped groove 191 is provided in the middle portion of the positioning block 109 , and a V-shaped block 181 is provided in the positioning groove 108 to cooperate with the V-shaped groove.

[0057] When positioning block 109 approaches positioning groove 108, V-shaped block 181 guides positioning block 109 into V-shaped groove 191. Because the geometric shapes of the two elements match, positioning block 109 automatically adjusts its position during insertion, ensuring that its centerline aligns with the centerline of positioning groove 108. The shape of V-shaped groove 191 effectively prevents positioning block 109 from shifting during insertion, thereby ensuring accurate positioning. Whether inserting vertically or diagonally, V-shaped groove 191 provides excellent guidance, ensuring the stability of positioning block 109's final position.

[0058] The presence of the self-alignment mechanism in the above structure significantly reduces reliance on manual intervention, reduces assembly complexity, and improves assembly efficiency. This is particularly important for large-scale production, as it can significantly shorten assembly time.

[0059] One side of the positioning groove 108 has a guide slope 182, and the positioning block 109 is provided with a positioning slope 192 corresponding to the guide slope. When the positioning block 109 is inserted into the positioning groove 108, the other side of the positioning block 109 is pressed against the inner wall of the positioning groove 108 through the cooperation of the guide slope 192 and the positioning slope 182.

[0060] As the positioning block 109 is inserted, the guide slope 182, through its inclined setting, can guide the positioning block 109 downward. This process not only allows the positioning block 109 to gradually fit against the inner wall of the positioning groove 108 to form a stable connection, but also ensures that the other side of the positioning block 109 is also firmly pressed, thereby achieving effective positioning in the vertical direction.

[0061] A sawtooth structure is provided between the other side of the positioning block 109 and the inner wall of the positioning groove 108, and the sawtooth structure limits the positioning block 109 and the positioning groove 108. The sawtooth structure can be a row of sharp sawtooth shapes, alternately arranged on one side of the positioning block 109 and the inner wall of the positioning groove 108.

[0062] When the positioning block 109 is inserted into the positioning slot 108, the interlocking serrations form a physical barrier to prevent the positioning block 109 from longitudinally moving. This limiting effect ensures that the assembly is not likely to loosen during long-term use and maintains its stability.

[0063] The technical means disclosed in the solutions of the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
