[0034] Please see Figures 1 to 3 One embodiment of the present invention provides a loudspeaker, including: a main body 10, a bass support 20, a bass component 30, a front cover support 40, and a tweeter component 50;

[0035] The subwoofer bracket 20 is mounted on the main body 10;

[0036] The bass component 30 is mounted on the bass bracket 20;

[0037] The front cover bracket 40 is assembled with the subwoofer bracket 20 and / or the main body 10;

[0038] The tweeter 50 is mounted between the front cover bracket 40 and the woofer 30. The woofer 30 presses the tweeter 50 against the front cover bracket 40. The tweeter 50 and the woofer 30 are arranged sequentially along a preset axis, achieving coaxial arrangement. This allows a single speaker to perform both high and low frequency functions, avoiding the need to add separate tweeters and woofers to other electronic devices. Furthermore, while the woofer bracket 20 mounts the woofer 30, it also restrains the tweeter 50 on the front cover bracket 40. Thus, the woofer bracket 20 and the front cover bracket 40 work together to restrain and fix the woofer 30 and the tweeter 50, simplifying the structure and avoiding the need for additional brackets that would increase the overall size if the woofer 30 and tweeter 50 were fixed separately.

[0039] Please see Figure 3 and Figure 4In some optional embodiments, a first positioning groove 41 is provided on the front cover bracket 40. The tweeter component 50 extends into the first positioning groove 41 and is positioned and engaged with the first positioning groove 41. The woofer component 30 restricts the tweeter component 50 within the first positioning groove 41, so that the tweeter component 50 cannot detach from the first positioning groove 41. By engaging with the first positioning groove 41 to restrict the position of the tweeter component 50, the tweeter component 50 is prevented from shaking, thereby improving the assembly stability of the tweeter component 50 and effectively ensuring stable sound quality.

[0040] In some alternative embodiments, a first sound outlet 42 is provided on the front cover bracket 40, and a portion of the tweeter component 50 extends into the first sound outlet 42 and is positioned and engaged with the first sound outlet 42. The first sound outlet 42 can restrict the position of the tweeter component 50, further improving the positional stability of the tweeter component 50, and the sound emitted by the tweeter component 50 can diffuse out from the first sound outlet 42, facilitating the sound propagation of the tweeter component 50.

[0041] In some optional embodiments, a second positioning groove 43 is provided on the front cover bracket 40, and a first positioning groove 41 is disposed in the second positioning groove 43. The bass component 30 extends into the second positioning groove 43 and is positioned and engaged with the second positioning groove 43. The second positioning groove 43 restricts the position of the bass component 30, thereby stabilizing the position of the bass component 30 relative to the front cover bracket 40, improving the assembly stability of the bass component 30, effectively ensuring stable sound quality, and also preventing the bass component 30 from slipping relative to the tweeter component 50, so that the bass component 30 can stably restrict the tweeter component 50.

[0042] In some alternative embodiments, a fixed step portion 44 is formed in the second positioning groove 43. The fixed step portion 44 is arranged around the first positioning groove 41. The bass component 30 presses against the fixed step portion 44. The front cover bracket 40 supports the bass component 30 through the fixed step portion 44, so that the bass component 30 is restricted by the front cover bracket 40 and the bass bracket 20, making the bass component 30 assembled stably. The tweeter component 50 is restricted by the bass component 30 and the front cover bracket 40, and can also be assembled more stably.

[0043] Please see Figure 5 In some alternative embodiments, the bass component 30 has a U-shaped iron 31 that extends into the second positioning groove and abuts against the fixed step portion 44 and the tweeter component 50. The U-shaped iron 31 has higher structural strength and can stably cooperate with other structures to limit the position, thereby limiting the bass component 30 and pressing against the tweeter component 50.

[0044] The specific structure of the bass component 30 can be selected according to actual needs. For example, in this embodiment, the bass component 30 includes a U-shaped iron 31, a first magnet 32, a washer 33, a second magnet 34, a voice coil 35, a diaphragm 36, a spider 37, and a suspension edge 38. The U-shaped iron 31 covers the voice coil 35 and forms a cavity around the voice coil 35. The first magnet 32, the washer 33, and the second magnet 34 are disposed in the cavity and arranged sequentially from the U-shaped iron 31 to the voice coil 35. The diaphragm 36 and the spider 37 are arranged around the voice coil 35. The suspension edge 38 is arranged around the diaphragm 36 and the spider 37. The diaphragm 36 and the spider 37 are both mounted on the suspension edge 38, and the suspension edge 38 is assembled with the bass support 20.

[0045] In some alternative embodiments, a plurality of magnetic return mounting slots 411 are provided in the first positioning groove 41. The plurality of magnetic return mounting slots 411 are arranged sequentially around a preset axis. The magnetic return mounting slots 411 are used to accommodate the tweeter magnetic return structure. The tweeter magnetic return structure can be directly assembled in the front cover bracket 40, which reduces the need to fix the relevant components of the tweeter assembly 50 separately, thereby simplifying the structure and making the speaker thinner.

[0046] Please see Figure 6 In some optional embodiments, the main body 10 is provided with an inner cavity 11, the inner cavity 11 having a second sound outlet 12, and a front cover bracket 40 disposed at the second sound outlet 12. The front cover bracket 40 is provided with multiple hollow slots 45 communicating with the inner cavity 11. The bass bracket 20 and the bass assembly 30 are installed in the inner cavity 11, and the sound emitted by the bass assembly 30 can diffuse outward from the hollow slots 45. During assembly, the tweeter 50 is installed in the first positioning groove 41 of the front cover bracket 40, and the bass assembly 30 is installed in the bass bracket 20. Then, the bass assembly 30 is installed in the second positioning groove 43, so that the bass bracket 20 is assembled with the front cover bracket 40. Then, the bass assembly 30 and the bass bracket 20 are extended from the second sound outlet 12 into the inner cavity 11, and the bass bracket 20 is assembled with the main body 10. The tweeter 50 and the bass assembly 30 are not integrated, so the bass assembly 30 or the tweeter 50 can be removed separately for inspection after subsequent disassembly and assembly.

[0047] The front cover bracket 40 can be assembled with the main body 10 and / or the subwoofer bracket 20. For example, in some optional embodiments, the main body 10 is provided with a first fixing ring portion 13 arranged around the second sound outlet 12, and the front cover bracket 40 is provided with a first fixing ring groove 46, with the first fixing ring portion 13 assembled with the first fixing ring groove 46; and / or, the subwoofer bracket 20 is provided with a second fixing ring portion 21 arranged around the second sound outlet 12, and the front cover bracket 40 is provided with a second fixing ring groove 47, with the second fixing ring portion 21 assembled with the second fixing ring groove 47. In this embodiment, the front cover bracket 40 is provided with a first fixing ring groove 46 and a second fixing ring groove 47. Of course, in other embodiments, only the first fixing ring groove 46 or the second fixing ring groove 47 may be provided.

[0048] The first fixing ring 13, in conjunction with the first fixing ring groove 46, assembles the front cover bracket 40 onto the main body 10. The first fixing ring 13 and the first fixing ring groove 46 can be fixed together by means of snap-fit, interference fit, or adhesive bonding. Alternatively, the first fixing ring 13 and the first fixing ring groove 46 can serve only a positioning function, or they can have a clearance fit. The second fixing ring 21 and the second fixing ring groove 47 assemble the front cover bracket 40 onto the bass speaker bracket 20, and their assembly method is similar to that of the first fixing ring 13 and the first fixing ring groove 46.

[0049] In some optional embodiments, the main body 10 is provided with a support step 14. The support step 14, the bass bracket 20, and the front cover bracket 40 are arranged sequentially along a preset axis. The opposite sides of the bass bracket 20 abut against the front cover bracket 40 and the support step 14, respectively. The support step 14 supports the bass bracket 20. The force from the front cover bracket 40 can be sequentially transmitted from the tweeter 50, the bass 30, and the bass bracket 20 to the support step 14, so that the main body 10 can support the front cover bracket 40, the tweeter 50, the bass 30, and the bass bracket 20, thereby improving the overall stress stability. In this embodiment, the support step 14 can be disposed in the inner cavity 11. In addition, the bass bracket 20 can be detachably fixed to the support step 14 by means of threaded parts, snap-fit ​​structures, etc., and this example is not limited to this one.
