Description

Technical Field

[0001] The utility model relates to the field of column sound boxes, in particular to a half-width progressive attenuation horn column sound box. Background Art

[0002] A column speaker is a specially designed speaker system that consists of multiple speaker units arranged vertically to form a columnar structure. In the professional speaker industry, column speakers made of multiple small-diameter speaker units are increasingly used in practical applications.

[0003] In the existing column speakers, each speaker unit has the same effect. When in use, it will form a reflection phenomenon when close to obstacles (such as floors, ceilings, etc.), and the sound field will appear to be insufficient in suspended parts. For this reason, we designed this half-width (plane mirror) progressive attenuation column speaker. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a half-width progressive attenuation speaker column speaker to solve the technical problem that the efficacy of each speaker unit in the existing column speaker is the same, which reduces its use effect.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a half-width progressive attenuation speaker column sound box, comprising a sound column body, a plurality of speakers installed inside the sound column body, and a speaker plate provided on the outer wall of the speaker, a beam splitter device installed on the outer surface of the speaker plate, a splicing assembly provided on the sound column body, and the splicing assembly includes a slot and a groove opened on both sides of the top of one sound column body and an insert installed on both sides of the bottom of the other sound column body, and a card slot is opened on one side of the insert, and a card block is provided inside the groove and penetrates into the slot.

[0006] By adopting the above technical solution, when the inserting block is fully inserted into the slot, the locking block is reset and moved into the slot, thereby locking and limiting the inserting block.

[0007] Furthermore, a spring is installed on one side of the interior of the groove, and one end of the spring is connected to the clamping block.

[0008] By adopting the above technical solution, when the block moves into the groove, it will squeeze the spring, causing the spring to be compressed, making it easier to push the block to reset and move.

[0009] Furthermore, a pull rod penetrating to the outside of the sound column body is installed on one side of the block, and one end of the pull rod is connected to a pull plate.

[0010] By adopting the above technical solution, it is convenient for the staff to pull the pull rod through the pull plate. When the pull rod moves, it will drive the card block to move, so that the card block is removed from the card slot.

[0011] Furthermore, the top of the clamping block and one side of the bottom of the inserting block are both arranged in an inclined surface.

[0012] By adopting the above technical solution, when the inserting block is inserted into the slot, the card block will be pushed to move toward the groove, so that the card block can be removed from the slot.

[0013] Furthermore, the inserting block is adapted to the slot, and the card block is adapted to the card slot.

[0014] By adopting the above technical solution, when two sound column bodies need to be spliced, the plug-in block at the bottom of one sound column body can be inserted into the slot, which facilitates the positioning of the sound column body first.

[0015] Furthermore, there are 12 speakers, each of which is a 3-inch full-range speaker.

[0016] By adopting the above technical solution, the speaker is arranged to facilitate the transmission of sound, thereby improving the use effect of the speaker.

[0017] Furthermore, the radiation angle of the sound column body is set to 17 degrees, and the deflection angle of adjacent speakers is 0.75 degrees.

[0018] Furthermore, the beam splitter device is made of ABS plastic material.

[0019] By adopting the above technical solution, the insulation performance of the beam splitter body is improved, and at the same time, the strength of the beam splitter body can be improved.

[0020] Furthermore, the block is slidably connected to the groove.

[0021] By adopting the above technical solution, the card block can be moved into the groove, thereby facilitating the movement of the card block.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. This utility model uses 12 3-inch full-range speakers, the radiation angle of the box is set to 17 degrees, and the deflection angle of adjacent speakers is 0.75 degrees. The four speakers at the top are set as the standard, and the sound is gradually attenuated towards the other end. It can be used in larger spaces and can be used in a plane mirror-like manner, that is, forming a suspended column speaker with 24 3-inch speakers, and improving the performance of the column speaker.

[0024] 2. The utility model provides a splicing component. When two sound column bodies need to be spliced, the plug-in block at the bottom of one sound column body can be inserted into the slot, which is convenient for positioning the sound column body first. When the plug-in block is inserted into the slot, it pushes the card block to move in the direction of the groove and squeezes the spring. When the plug-in block is fully inserted into the slot, the spring stretches and pushes the card block to reset and move into the card slot, and then the plug-in block can be locked and limited. In this way, the splicing between the sound column bodies can be completed, and the stability of the sound column bodies after splicing is improved, preventing the sound columns from falling off.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The following describes an embodiment of the present invention based on its overall structure.

[0033] Example 1:

[0034] A half-width progressive attenuation horn column speaker, such as Figure 1-Figure 5As shown, it includes a sound column body 1, a plurality of speakers 3 are installed inside the sound column body 1, and a speaker plate 2 is provided on the outer wall of the speaker 3, and a beam splitter device 4 is installed on the outer surface of the speaker plate 2. A splicing component 5 is provided on the sound column body 1, and 12 speakers 3 are provided. The speakers 3 are 3-inch full-range speakers. The arrangement of the speakers 3 facilitates the transmission of sound. The radiation angle of the sound column body 1 is set to 17 degrees, and the deflection angle of adjacent speakers 3 is 0.75 degrees. The beam splitter device 4 is made of ABS plastic material to improve the insulation performance of the beam splitter body 4 and at the same time improve the strength of the beam splitter body 4.

[0035] See Figure 2-Figure 4 The splicing component 5 includes slots 502 and grooves 505 on both sides of the top of one sound column body 1 and plug-in blocks 501 installed on both sides of the bottom of the other sound column body 1, and a card slot 503 is opened on one side of the plug-in block 501. A card block 504 is provided inside the groove 505 and penetrates into the slot 502. When the plug-in block 501 is fully inserted into the slot 502, the card block 504 resets and moves into the card slot 503, thereby locking the plug-in block 501. A spring 506 is installed on one side of the groove 505, and one end of the spring 5056 is connected to the card block 504. When the card block 504 moves into the groove 505, it squeezes the spring 506, causing the spring 506 to be compressed, which facilitates the subsequent pushing of the card block 504 to reset and move.

[0036] See Figure 2-Figure 5 , a pull rod 507 is installed on one side of the block 504 and passes through the outside of the sound column body 1. One end of the pull rod 507 is connected to a pull plate 508, which is convenient for the staff to pull the pull rod 507 through the pull plate 508. When the pull rod 507 moves, it will drive the block 504 to move, so that the block 504 is moved out of the slot 503. The plug-in block 501 is adapted to the slot 502, and the block 504 is adapted to the slot 503. When two sound column bodies 1 need to be spliced, the plug-in block 501 at the bottom of one sound column body 1 can be inserted into the slot 502, which is convenient for positioning the sound column body 1 first. The block 504 is slidably connected to the groove 505 so that the block 504 can be moved into the groove 505, thereby facilitating the movement of the block 504.

[0037] Example 2:

[0038] On the basis of the above embodiment 1, in order to facilitate the splicing of the sound column body 1, the following method is adopted without requiring the staff to pull the pull plate 508 to remove the card block 504 from the slot 502 when splicing the sound column body 1.

[0039] Specifically, the top of the card block 504 and the bottom side of the insertion block 501 are both inclined. When the insertion block 501 is inserted into the slot 502, the insertion block 501 will contact the card block 504, and the bottom side of the insertion block 501 and the top of the card block 504 are both inclined. As the insertion block 501 continues to move downward, the insertion block 501 will first push the card block 504 to move toward the groove 505, so that the card block 504 can be moved out of the slot 502 and the card block 504 squeezes the spring 506.

[0040] The working principle of this utility model is as follows: first, 12 3-inch full-range speakers are used, the radiation angle of the column speaker is set to 17 degrees, and the deflection angle of adjacent speakers is 0.75 degrees; the four speakers at the top are set as the standard, and the attenuation gradually decreases towards the other end; it is used in a larger space;

[0041] When two sound column bodies 1 need to be spliced ​​together, the insert block 501 at the bottom of one sound column body 1 can be inserted into the slot 502 to facilitate positioning of the sound column body 1 first. When the insert block 501 is inserted into the slot 502, it pushes the card block 504 to move toward the groove 505 and squeezes the spring 506. When the insert block 501 is fully inserted into the slot 502, the spring 506 stretches and pushes the card block 504 to return and move into the card slot 503, thereby locking the insert block 501. In this way, the splicing of the sound column bodies 1 can be completed, forming a suspended sound column speaker box with twenty-four 3-inch speakers.
