[0029] This utility model discloses a compact speaker with good bass performance, which solves the technical problem that the bass speaker of existing compact speakers is installed inside the cabinet, which makes the bass speaker prone to sound blockage and thus results in poor bass performance.

[0030] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figs. 1-3The utility model discloses a compact sound box with good bass effect, including the box 1, the first loudspeaker assembly and bass loudspeaker 4 of setting up along the horizontal direction are arranged in the box 1, the first loudspeaker assembly includes treble loudspeaker 2 and bass loudspeaker 4 along the height direction of the box 1 is arranged, specifically, in this embodiment, treble loudspeaker 2, medium -pitch loudspeaker 3 and bass loudspeaker 4 are arranged in L type structure,

[0032] Wherein, the lateral wall of the box 1 is provided with bass sound hole 5, the sound outlet end of bass loudspeaker 4 is provided with reflector 6, and the reflector 6 is used to reflect the bass emitted by the bass loudspeaker 4 to the bass sound hole 5.

[0033] In the compact sound box of the embodiment, the reflector 6 is arranged at the sound outlet end of the bass loudspeaker 4, which can reflect the bass emitted by the bass loudspeaker 4 to the bass sound hole 5, ensuring that the bass can flow out of the bass sound hole 5, effectively improving the bass effect of the compact sound box.

[0034] Further, the box 1 in the embodiment includes a top plate 101, a bottom plate, and a front side plate 102, a rear side plate, a left side plate, and a right side plate 103 surrounding the top plate 101 and the bottom plate;

[0035] The treble loudspeaker 2 and the medium -pitch loudspeaker 3 are arranged in the height direction of the box 1 on the front side plate 102, and the sound outlet directions of the treble loudspeaker 2 and the medium -pitch loudspeaker 3 are both arranged towards the outside of the front side plate 102, and the bass loudspeaker 4 is located on the side away from the sound outlet end of the medium -pitch loudspeaker 3, so the above three loudspeakers are arranged in L type structure;

[0036] The left side plate and / or the right side plate 103 is provided with the bass sound hole 5, the sound outlet end of the bass loudspeaker 4 is arranged towards the bottom plate, and the reflector 6 is located between the sound outlet end of the bass loudspeaker 4 and the bottom plate.

[0037] It should be noted that through the above design, when the bass loudspeaker 4 emits bass, the reflector 6 reflects the bass to the bass sound hole 5, thereby improving the bass effect of the compact sound box.

[0038] Specifically, the bass sound hole 5 in the embodiment is located in the extension direction of the reflecting surface of the reflector 6.

[0039] It should be noted that through the above design, the reflector 6 can accurately reflect the bass to the bass sound hole 5, thereby ensuring the bass effect of the compact sound box.

[0040] In addition, the reflector 6 in this embodiment can specifically adopt a conical structure, wherein the arc surface of the conical reflector 6 is a reflective surface used to emit bass frequencies.

[0041] Furthermore, in this embodiment, a sound guide tube 7 is also installed inside the bass sound outlet 5.

[0042] It should be noted that in this embodiment, the sound guide tube 7 mainly guides the bass sound reflected by the reflector 6.

[0043] Furthermore, due to the performance requirements of the speaker enclosure, the midrange speaker 3 and the woofer 4 must be equipped with independent chambers to meet the requirements of mid-frequency and low-frequency vibration and sound generation. Therefore, a spacer structure must be provided between the midrange speaker 3 and the woofer 4.

[0044] The aforementioned spacing structure has various structural forms, such as Fig. 2 As shown, in the first specific embodiment, for cases requiring a larger midrange cavity, the partition structure may include a first partition 9, wherein the first partition 9 is disposed inside the enclosure 1 and divides the interior of the enclosure 1 into a first cavity 10 and a second cavity 11;

[0045] The tweeter 2 and the midrange speaker 3 are located in the first cavity 10, and the woofer 4 is located in the second cavity 11. Specifically, since the woofer 4 is larger, the volume of the first cavity 10 is smaller than the volume of the second cavity 11.

[0046] It should also be noted that in the above specific embodiment, the midrange speaker 3 and the tweeter 2 are placed in the first cavity 10, and the volume of the first cavity 10 where the midrange speaker 3 is located is expanded as much as possible while meeting the volume requirements of the second cavity 11 where the woofer 4 is located, so as to ensure the midrange effect of the compact speaker box.

[0047] like Fig. 3 As shown, in the second specific embodiment, to ensure the volume of the midrange cavity, the partition structure includes a second partition 12, wherein the second partition 12 is disposed inside the enclosure 1 and divides the interior of the enclosure 1 into a third cavity 13 and a fourth cavity 14.

[0048] The midrange speaker 3 is located in the third cavity 13, and the tweeter 2 and the woofer 4 are located in the fourth cavity 14. Specifically, since the woofer 4 is larger, the volume of the third cavity 13 is smaller than the volume of the fourth cavity 14.

[0049] In addition, it should be noted that the middle speaker 3 is arranged in the third cavity 13 alone, which can expand the volume of the second cavity 11 as much as possible, so that the second cavity 11 has a larger acoustic volume, and the sound box can output stronger and more submerged bass.

[0050] Further, as shown in the box 1 in the embodiment is connected with the inverted phase pipe 8; Figs. 1-3

[0051] The inverted phase pipe 8 is communicated with the second cavity 11 or the fourth cavity 14.

[0052] Specifically, in the direction from the inside of the box 1 to the outside of the box 1, the cross-sectional area of the inverted phase pipe 8 gradually increases.

[0053] It should be noted that through the above design, the design of the inverted phase pipe 8 can make full use of the vibration of the non-playing end of each speaker, so that the sound wave is strengthened, thereby strengthening the bass effect of the sound box, which is beneficial to improve the sound quality of the sound box.

[0054] The compact sound box with good bass effect is described in detail above, and for those skilled in the art, according to the idea of the embodiment of the utility model, the specific implementation and application range will be changed, and the above description should not be understood as a limitation of the utility model.​
