[0003] To solve the above problems, this technical solution provides a dual-magnet drive speaker.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A dual-magnet drive speaker, including

[0006] A speaker bracket, comprising an inner cavity and a central column disposed at the center of the inner cavity;

[0007] An internal magnetic mechanism includes an internal magnet sleeved on the central column and an Nevada superimposed on the internal magnet;

[0008] An external magnet mechanism includes an external magnet sleeved around the periphery of the inner magnet and spaced apart therefrom, and an external washer stacked on the external magnet;

[0009] A diaphragm is disposed on the speaker bracket;

[0010] The PCB board is mounted on the speaker bracket.

[0011] As described above, in a dual-magnetic driven speaker, the inner cavity sidewall is provided with an outwardly protruding cavity, and the sidewall of the protruding cavity is provided with a sound outlet hole communicating with the outside.

[0012] As described above, in a dual-magnetic driven horn, at least three of the convex cavities are arranged circumferentially and evenly around the central column.

[0013] As described above, in a dual-magnetic driven loudspeaker, a tuning mesh is provided on the outer side of the loudspeaker bracket for covering the sound outlet.

[0014] As described above, in a dual-magnetic driven horn, the horn bracket further includes a support portion disposed on the outer periphery of the inner cavity opening and used for connection with the diaphragm, the support portion communicating with the convex cavity.

[0015] As described above, in a dual-magnetic driven speaker, a limiting ring is provided on the bottom of the speaker bracket for limiting the position of the PCB board.

[0016] The dual-magnet drive speaker described above also includes a voice coil disposed on the diaphragm.

[0017] In a dual-magnetic driven speaker as described above, the voice coil extends from the diaphragm into the gap between the inner washer and the outer washer.

[0018] As described above, a dual-magnetic driven speaker has a first notch on the support portion and a second notch on the speaker bracket that makes way for the straight path from the first notch to the PCB board.

[0019] The beneficial effects of this application are:

[0020] This invention provides a dual-magnetic-driven speaker. Through an external magnetic mechanism and an internal magnetic mechanism, the dual-magnetic drive allows for more stable and powerful diaphragm vibration via a stronger magnetic field, resulting in more accurate reproduction of sound details. This allows for better presentation of tonal nuances such as instrument timbre and subtle emotional changes in vocals. Enhanced bass performance: The stronger magnetic force drives the diaphragm to produce a larger amplitude, resulting in deeper and more substantial bass, while maintaining bass elasticity and clarity, avoiding muddiness.

[0024] Figure 3 for Figure 1 A half-section view. Detailed Implementation

[0025] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] A dual-magnet drive speaker, including

[0027] The speaker bracket 1 includes an inner cavity 11 and a central column 12 disposed at the center of the inner cavity 11;

[0028] The inner magnetic mechanism 2 includes an inner magnet 21 sleeved on the central column 12, and an Nevada 22 stacked on the inner magnet 21;

[0029] The external magnetic mechanism 3 includes an external magnet 31 sleeved around the outer periphery of the inner magnet 21 and spaced apart therefrom, and an external washer 32 stacked on the external magnet 31;

[0030] Diaphragm 4 is disposed on the speaker bracket 1;

[0031] PCB board 5 is mounted on the speaker bracket 1.

[0032] This invention provides a dual-magnetic-driven speaker. Through an external magnetic mechanism and an internal magnetic mechanism, the dual-magnetic drive allows for more stable and powerful diaphragm vibration via a stronger magnetic field, resulting in more accurate reproduction of sound details. This allows for better presentation of tonal nuances such as instrument timbre and subtle emotional changes in vocals. Enhanced bass performance: The stronger magnetic force drives the diaphragm to produce a larger amplitude, resulting in deeper and more substantial bass, while maintaining bass elasticity and clarity, avoiding muddiness.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the inner cavity 11 has an outwardly protruding cavity 13 on its side wall, and the side wall of the cavity 13 has a sound outlet 14 that connects it to the outside.

[0034] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, at least three of the convex cavities 13 are arranged circumferentially and evenly spaced around the central column 12. This optimizes the sound field and the balance of the three frequencies: the annular triangular symmetrical structural design allows sound waves to diffuse and reflect evenly in the rear cavity of the earphone, reducing mutual interference between sound waves, making the sound field wider, and the connection of the three frequencies (high, mid, and low) more natural and balanced, avoiding any one frequency band from being too prominent or lacking.

[0035] Reduced resonance and distortion: This symmetrical structure can effectively suppress standing waves and abnormal resonances in the rear cavity, making the sound purer, reducing distortion caused by resonance, making the listening experience more comfortable, and reducing fatigue during long-term listening.

[0036] Enhance sound localization: Uniform sound wave diffusion helps enhance the spatial localization of sound. When listening to music, watching movies, or playing games, users can more clearly perceive the direction and distance of the sound source, thus enhancing immersion.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the speaker bracket 1 is provided with a tuning mesh 15 on its outer side for covering the sound outlet 14. The tuning mesh has an adhesive backing layer and can be attached to the speaker bracket. The sound outlet is also the tuning hole; the evenly distributed tuning holes ensure balanced airflow and reduce distortion caused by diaphragm vibration.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the speaker bracket 1 further includes a support portion 17 disposed on the outer periphery of the opening of the inner cavity 11 and used for connection with the diaphragm 4, the support portion 17 communicating with the convex cavity 13.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the bottom of the speaker bracket 1 is provided with a limiting ring 16 for limiting the PCB board 5, which facilitates installation.

[0040] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, a voice coil 6 disposed on the diaphragm 4 is also included. This is beneficial for improving sound quality.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the voice coil 6 extends from the diaphragm 4 into the gap between the inner washer 22 and the outer washer 32.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, the support portion 17 is provided with a first notch 18 and a second notch 19 provided on the speaker bracket 1 to make way for the straight path from the first notch 18 to the PCB board 5. This facilitates wiring.

[0043] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
