DETAILED DESCRIPTION

[0027] The present application discloses a compact speaker box, which is used to solve the technical problem of large overall height of the existing three-way speaker box and unable to realize compact design.

[0028] In order to make the personnel in the technical field better understand the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the present application.

[0029] Please refer to Figs. 1-3 The compact speaker box provided by the embodiment of the present application comprises a box 1, and a first loudspeaker assembly and a woofer 4 arranged in a horizontal direction are arranged in the box 1, wherein the first loudspeaker assembly comprises a tweeter 2 and a midrange speaker 3 arranged in the height direction of the box.

[0030] Through the above design, the woofer 4, the tweeter 2 and the midrange speaker 3 are not arranged on the same straight line, thereby effectively reducing the overall height of the speaker box, so that the speaker box can realize compact design, thereby making the speaker box applicable to the scene with small space.

[0031] Further, as Figs. 1-3 shown, the box 1 in the embodiment is specifically a cuboid structure, which specifically comprises a top plate 101, a bottom plate, and a front side plate 102, a left side plate, a right side plate 103 and a rear side plate arranged between the top plate 101 and the bottom plate;

[0032] The tweeter 2 and the woofer 4 are arranged on the front side plate 102 in the height direction of the box 1, and the sound output directions of the tweeter 2 and the midrange speaker 3 are both arranged towards the outside of the front side plate 102.

[0033] The woofer 4 is located on the side away from the sound output end of the midrange speaker 3, and the sound output direction of the woofer 4 is set towards the base plate.

[0034] Specifically, in this embodiment, the tweeter 2 is located above the midrange speaker 3.

[0035] It should be noted that in this embodiment, the tweeter 2, midrange speaker 3 and woofer 4 are arranged in an L-shaped structure inside the enclosure 1. In other specific embodiments, the speakers can also be arranged in other structures. This embodiment does not limit this, as long as the tweeter 2 and midrange speaker 3 are set on the first plane inside the enclosure 1 and the woofer 4 is set on the second plane inside the enclosure 1.

[0036] In addition, the left side panel and / or right side panel 103 in this embodiment are provided with sound outlet holes 5 for use with the subwoofer 4.

[0037] It should be noted that, through the above design, the bass emitted by the subwoofer 4 can be played out from the sound holes 5 on the left and right side panels 103, thereby meeting the user's demand for bass effect.

[0038] Furthermore, such as Fig. 1 As shown, the sound outlet 5 in this embodiment is provided with a sound guide tube 13.

[0039] It should be noted that, through the above design, the sound guide tube 13 can guide the bass emitted by the subwoofer 4.

[0040] 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.

[0041] 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 11, wherein the first partition 11 is disposed inside the enclosure 1 and divides the interior of the enclosure 1 into a first cavity 7 and a second cavity 8;

[0042] The tweeter 2 and the midrange speaker 3 are located in the first cavity 7, and the woofer 4 is located in the second cavity 8. Specifically, since the woofer 4 is larger, the volume of the first cavity 7 is smaller than the volume of the second cavity 8.

[0043] 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 7, and the volume of the first cavity 7 where the midrange speaker 3 is located is expanded as much as possible while meeting the volume requirements of the second cavity 8 where the woofer 4 is located, so as to ensure the midrange effect of the compact speaker box.

[0044] 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 9 and a fourth cavity 10;

[0045] The midrange speaker 3 is located in the third cavity 9, and the tweeter 2 and the woofer 4 are located in the fourth cavity 10. Specifically, since the woofer 4 is larger, the volume of the third cavity 9 is smaller than the volume of the fourth cavity 10.

[0046] It should also be noted that by placing the midrange speaker 3 separately in the third cavity 9, the volume of the second cavity 8 where the woofer 4 is located can be expanded as much as possible, thereby ensuring that the second cavity 8 has a larger acoustic volume, which in turn allows the speaker to output a more powerful and deeper bass.

[0047] Furthermore, such as Figs. 1-3 As shown, in this embodiment, the housing 1 is connected to a phase inverter 6;

[0048] The phase inverter 6 is connected to the second cavity 8 or the fourth cavity 10.

[0049] Specifically, the cross-sectional area of ​​the phase inverter 6 gradually increases along the direction from the inside of the housing 1 to the outside of the housing 1.

[0050] It should be noted that, through the above design, the design of the bass reflex tube 6 can make full use of the vibration of the non-playing ends of each speaker to strengthen the sound waves, thereby enhancing the bass effect of the speaker and improving the sound quality of the speaker.

[0051] The above provides a detailed description of a compact speaker provided by this utility model. For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
