[0016] A further preferred embodiment: the lower magnetic guide plate of the speaker is bent downwards on all four sides.

[0017] Beneficial effects:

[0018] 1. By incorporating elastic clips, the edge of the stainless steel sheet can be embedded into the interior, and the protrusions on the outer side contact the upper end of the stainless steel sheet, enhancing the robustness of the assembly between components. During long-term use, even when the speaker is in a continuous vibration and sound-producing state, it effectively prevents problems such as loosening of components and misalignment of the magnetic circuit, thereby fundamentally ensuring the stability of the speaker structure and laying the foundation for long-term stable operation. This indirectly extends the lifespan of the speaker, reduces the probability of failure due to structural loosening, and allows users to use the speaker device stably for a long time.

[0019] 2. By incorporating a metal insert located between the stainless steel sheet and the outer side of the lower magnetic guide plate of the speaker, the connection between the stainless steel sheet and the bracket is further enhanced, thereby ensuring the reliability and service life of the speaker device.

[0020] 3. In summary, this novel single-sided vibration-damping speaker, through the inclusion of structures such as elastic clips, provides a stable magnetic field for the voice coil through a magnetic circuit system consisting of an upper magnetic guide plate, a speaker magnet, and a lower magnetic guide plate, ensuring consistent vibration and improving sound clarity and fidelity. The single-sided vibration-damping design of the stainless steel sheet, combined with its tight assembly with the elastic clips, which are embedded in the edge of the stainless steel sheet and have an outer protrusion contacting the upper end of the stainless steel sheet, enhances the assembly's firmness, preventing loosening of components and magnetic circuit misalignment during long-term use, effectively increasing speaker power and extending reliability testing time.

[0026] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0027] Please see Figure 1-4 In this embodiment of the present invention, a novel single-sided vibration-damping horn includes: a horn bracket 1; a stainless steel sheet 2 disposed above the horn bracket 1; a horn voice coil 3 disposed inside the horn bracket 1; a lower magnetic guide plate 6 disposed above the stainless steel sheet 2; an upper magnetic guide plate 4 fixedly installed inside the horn voice coil 3, a horn magnet 5 installed at the upper end of the upper magnetic guide plate 4; a horn diaphragm 101 disposed inside the horn bracket 1, with an elastic buckle 7 and a metal insert 8 at the upper end; two welding points 102 disposed on the side of the horn bracket 1; the bottom of the lower magnetic guide plate 6 contacts the upper end of the horn voice coil 3, and the lower magnetic guide plate 6 is embedded between the stainless steel sheet 2 and the horn magnet 5; a connecting block is disposed at the bottom of the stainless steel sheet 2, and the connecting block is connected to the bottom of the stainless steel sheet 2 and the upper end of the horn bracket 1 respectively by adhesive; the horn magnet 5 is located at the upper end of the upper magnetic guide plate 4; the lower magnetic guide plate 6 is bent downwards on all four sides.

[0028] When an electrical signal is input through the two solder points 102, a current is generated in the speaker voice coil 3. In the magnetic circuit system composed of the upper magnetic plate 4, the speaker magnet 5, and the lower magnetic plate 6, the voice coil is subjected to magnetic force and generates mechanical vibration. This vibration is transmitted to the speaker diaphragm 101, causing it to vibrate and produce sound. At the same time, the stainless steel sheet 2 achieves single-sided vibration damping through its own structural characteristics, suppressing resonance during speaker operation. The elastic buckle 7 ensures that all components are firmly assembled, preventing magnetic circuit misalignment or component loosening. The upper magnetic plate 4, speaker magnet 5, and lower magnetic plate 6 provide a stable magnetic field for the voice coil, ensuring the consistency of vibration and improving the clarity and fidelity of the sound quality. The single-sided vibration damping design of the stainless steel sheet 2 effectively suppresses resonance, reduces noise interference, and makes the sound purer. The elastic buckle 7 achieves the snap-fit ​​fixation of each component, making it less prone to component loosening or magnetic circuit misalignment during long-term use. It also enhances the bonding strength between the stainless steel sheet 2 and the bracket. The stainless steel sheet 2 is glued to the speaker bracket 1 through the connecting block, further strengthening the structural stability and extending the speaker's service life.

[0029] In this embodiment of the utility model, the edge of the stainless steel sheet 2 can be embedded in the elastic buckle 7, and the outer side of the elastic buckle 7 is provided with a protrusion, the bottom of the protrusion is in contact with the upper end of the stainless steel sheet 2; the metal insert 8 is disposed between the stainless steel sheet 2 and the outer side of the lower magnetic guide plate 6 of the speaker.

[0030] After an electrical signal is input, the speaker voice coil 3 generates a current. In the magnetic circuit system consisting of the upper magnetic plate 4, the speaker magnet 5, and the lower magnetic plate 6, the voice coil vibrates mechanically under the action of the magnetic field force. This vibration is transmitted to the speaker diaphragm 101, causing it to produce sound. At the same time, the edge of the stainless steel sheet 2 is embedded in the elastic buckle 7, and the protrusion on the outer side of the elastic buckle 7 contacts the upper end of the stainless steel sheet 2, further enhancing the structural stability. The stainless steel sheet 2 suppresses resonance through its own characteristics, and together with the synergistic effect of the magnetic circuit system and the vibration system, achieves efficient electroacoustic conversion and vibration reduction.

[0031] The edge of the stainless steel sheet 2 is embedded inside the elastic buckle 7, and the outer protrusion of the elastic buckle 7 contacts the upper end of the stainless steel sheet 2, so as to avoid the problem of loosening of components and magnetic circuit misalignment during long-term use; the metal insert 8 is set between the stainless steel sheet 2 and the outer side of the lower magnetic guide plate 6 of the speaker, which helps to fix the stainless steel sheet 2 on the speaker bracket 1 and further enhances the stability of the connection between the stainless steel sheet 2 and the speaker bracket 2.

[0032] When an electrical signal is input, the speaker voice coil 3 generates a current. In the magnetic circuit system consisting of the upper magnetic plate 4, the speaker magnet 5, and the lower magnetic plate 6, the voice coil is subjected to magnetic force and generates mechanical vibration. This vibration is transmitted to the speaker diaphragm 101 to produce sound. During the sound production process, the stainless steel sheet 2 plays a single-sided damping role, suppressing resonance and ensuring pure sound quality.

[0033] Installation process: First, combine the speaker voice coil 3 and speaker diaphragm 101 with the speaker bracket 1, and combine the stainless steel sheet 2 with the lower magnetic guide plate 6 of the speaker. Then, assemble the upper magnetic guide plate 4 and speaker magnet 5 together on the lower magnetic guide plate 6. Finally, install the stainless steel sheet 2 on the speaker bracket 1 to complete the installation of the entire device.
