DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] Example

[0024] Please refer to Figure 1-Figure 4 , box speakers, including:

[0025] A rectangular box body 1, wherein the rectangular box body 1 has a receiving cavity 100 therein. Specifically, the receiving cavity 100 passes through the front surface of the rectangular box body 1, and side openings 11 that pass through the receiving cavity 100 are formed at both ends of the rectangular box body 1;

[0026] Two groups of speaker components 2 symmetrically arranged in the accommodating cavity 100 include a mounting tube 20 and a nut sleeve 24. The mounting tube 20 is provided with a conical accommodating groove 200 for inserting the speaker body 21 on the front side, and a limiting groove 201 intersecting the conical accommodating groove 200 is provided on the back side of the mounting tube 20. Specifically, the limiting groove 201 is arranged along the inner central axis of the mounting tube 20. A connecting column 23 having one end fixedly connected to the speaker body 21 is inserted into the limiting groove 201. The other end of the connecting column 23 extends to the outer side of the mounting tube 20, and the other end surface of the connecting column 23 is provided with an end thread 231. The nut sleeve 24 is threadedly connected to the end of the connecting column 23 through the end thread 231. Specifically, the bottom end surface of the speaker component 2 contacts the bottom side surface of the accommodating cavity 100.

[0027] The positioning component 3 can drive the two groups of speaker components 2 to move toward or away from the side opening 11 synchronously.

[0028] In an optional embodiment: the cross-sectional area of ​​the nut sleeve 24 is larger than the cross-sectional area of ​​the limiting groove 201, and a rotating block 25 is fixedly connected to one end of the outer side of the nut sleeve 24 away from the connecting column 23, and the connecting column 23 is conveniently rotated by the rotating block 25. When the nut sleeve 24 is threadedly connected to the end thread 231, the end surface of the nut sleeve 24 close to the mounting tube 20 can contact the outer end surface of the mounting tube 20. When in contact, one end of the connecting column 23 in the axial direction is limited by the nut sleeve 24, and the other end of the speaker body 21 in the axial direction is limited by being larger than the connecting column 23, so that the speaker body 21 is limited and fixed in the mounting tube 20.

[0029] In an optional embodiment: buffer limit blocks 22 are fixedly connected to both sides of the exterior of the speaker body 21. When the speaker body 21 is inserted into the conical receiving groove 200, on the one hand, the buffer limit blocks 22 can allow the speaker body 21 to be stably squeezed and inserted into the conical receiving groove 200, limiting the speaker body 21 in the conical receiving groove 200 to prevent the speaker body 21 from rotating. On the other hand, the speaker body 21 can be buffered and shock-absorbing to avoid bumps on the speaker body 21. Of course, the connecting column 23 in the present application is configured to be rectangular at one end close to the speaker body 21 to further prevent the speaker body 21 from rotating.

[0030] In an optional embodiment: a first filter 12 is clamped in the side opening 11, and a second filter 13 is fixedly connected to the front side of the accommodating cavity 100. Specifically, the first filter 12 and the second filter 13 prevent dust from entering the rectangular box 1.

[0031] In an optional embodiment: the positioning assembly 3 includes an adjustment shell 30 fixedly connected to the back side of the accommodating cavity 100, a top groove 31 is opened at the end of the adjustment shell 30 close to the speaker assembly 2, a threaded rod 34 is rotatably connected between the two ends of the inner wall of the adjustment shell 30, and the surface of the threaded rod 34 is symmetrically threadedly connected to two adjustment blocks 32, and the end of the adjustment block 32 close to the mounting tube 20 is fixedly connected to an L-shaped connecting frame 33, and the end of each connecting frame 33 away from the adjustment block 32 passes through the top groove 31 and is fixedly connected to the inner side of a mounting tube 20.

[0032] In an optional embodiment: the interior of the adjustment shell 30 is fixedly connected with a guide rod 35 arranged parallel to the threaded rod 34, the bottom ends of the two adjustment blocks 32 are slidably sleeved on the surface of the guide rod 35, one end of the threaded rod 34 movably penetrates to the outside of the rectangular box 1 and is fixedly connected with a turning handle, and the threaded rod 34 is easily rotated by the turning handle. Specifically, the surface of the threaded rod 34 is provided with two symmetrical threads, and the inner wall of the top of the adjustment block 32 is provided with a thread groove corresponding to the thread, and the two adjustment blocks 32 are limited by the guide rod 35. When the threaded rod 34 is rotated, the connecting frame 33 on the two adjustment blocks 32 can be moved toward or away from each other.

[0033] In an optional embodiment: one of the speaker bodies 21 is a high-frequency speaker, and the other speaker body 21 is a low-frequency speaker.

[0034] Specifically, when installing the speaker body 21 on the mounting tube 20 in the rectangular box 1, the connecting column 23 at one end of the speaker body 21 is inserted into the limiting groove 201. When the buffer limiting block 22 conflicts with the conical receiving groove 200, the nut sleeve 24 is rotated and threadedly connected to the end thread 231 until one end surface of the nut sleeve 24 conflicts with one end surface of the mounting tube 20, so that the speaker body 21 is quickly and stably fixed to the mounting tube 20.

[0035] When adjusting the listening experience of music, the distance between the two speaker components 2 in the accommodating cavity 100 is adjusted by the position adjustment component 3 to change the relative distance between the high-frequency speaker and the low-frequency speaker, thereby changing the sound azimuth of the high-frequency speaker and the low-frequency speaker, so that the listening experience can be flexibly adjusted;

[0036] When the speaker needs to be maintained, repaired or replaced, first take out the first filter 12 in the side port 11, then drive the two sets of speaker components 2 to move away from each other through the adjustment component 3, so that the two speaker components 2 pass through the side port 11 and move out to the outside of the rectangular box 1, then rotate the nut sleeve 24 to make the nut sleeve 24 disengage from the connecting column 23, and then pull out the speaker body 21 from the speaker component 2, so that the speaker body 21 can be quickly taken out, which is convenient for maintenance, repair or replacement of the speaker body 21.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
