Technical Field

[0001] The utility model relates to the field of column speakers, in particular to a beam splitter device for improving sound quality and timbre. Background Art

[0002] A column speaker is a specially designed speaker system composed of multiple speaker units arranged vertically to form a columnar structure. This design gives the column speaker enhanced vertical directivity, allowing it to project sound in a focused direction. This makes it ideal for situations where sound needs to be focused on a specific area, such as lectures, conferences, or cinemas. Column speakers are also equipped with beam splitters to enhance sound quality and timbre.

[0003] The existing beam splitter device that improves sound quality and tone, when the sound column speaker uses a 3-inch full-range speaker, there will be mixing and interference when restoring the sound in the mid- and high-frequency bands, resulting in a listening experience with poor layering and clarity, thereby reducing the effectiveness of the sound column speaker. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a beam splitter device that improves the sound quality and timbre, so as to solve the technical problem that the sound column speaker will cause mixing and interference when restoring sound in the mid- and high-frequency bands.

[0020] By adopting the above technical solution, the pressing plate can slide inside the through groove, thereby improving the stability of the pressing plate when moving.

[0021] Furthermore, the beam splitter body is made of ABS plastic material.

[0022] By adopting the above technical solution, the insulation performance of the beam splitter body is improved, and the impact resistance of the beam splitter body is also improved.

[0023] In summary, the present invention has the following beneficial effects:

The utility model installs a beam splitter device in front of the speaker plate of a 3-inch speaker to collect high-frequency sound waves and separate mid- and low-frequency sound waves, so as to minimize the mutual mixing and interference of mid- and low-frequency sound waves and high-frequency sound waves, thereby improving the sound quality and timbre, and enhancing the layering and clarity of the sound field;

[0025] 2. The utility model is provided with a spring, a clamping column, a clamping hole, a mounting hole, a mounting column and a pressure plate. When installing the beam splitter body, the beam splitter body is sleeved on the mounting column, and the pressure plate can be pressed first during sleeve connection, so that the pressure plate drives the movable block to move, and drives the clamping column to move into the cavity, and then the beam splitter body is moved so that the clamping hole on the mounting ear is aligned with the clamping column. At this time, the pressure plate is no longer pressed, and the spring is stretched to push the movable block to reset and move, and the clamping column to reset and move, so that the clamping column is clamped into the clamping hole and then locks the mounting ear to limit the position, and the installation of the beam splitter body can be completed. When disassembling, it is only necessary to press the pressure plate so that the clamping column moves out of the clamping hole and no longer limits the mounting ear, so that the beam splitter body can be removed. In this way, the beam splitter body can be quickly disassembled and assembled without the need for bolts. The disassembly and assembly process is simple and convenient, thereby improving the disassembly and assembly efficiency of the beam splitter body. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0034] The following describes an embodiment of the present invention based on its overall structure.

[0035] Example 1:

[0036] A beam splitter device that improves sound quality and timbre, such as Figures 1-6 As shown, it includes a beam splitter body 1 and an audio speaker board 3. Mounting ears 10 are installed on all four sides of the beam splitter body 1, and a mounting hole 11 is opened on the mounting ear 10. A clamping hole 7 is opened above the inner part of the mounting hole 11. A plurality of mounting columns 2 are installed on the audio speaker board 3. A cavity 4 is opened inside the mounting column 2. A movable block 12 is provided inside the cavity 4, and a clamping column 6 is provided on the top of the movable block 12, which passes through the outside of the mounting column 2. After the clamping column 6 is moved out of the clamping hole 7, it no longer locks and limits the beam splitter body 1. At this time, the beam splitter body 1 can be taken out, which is convenient for disassembly of the beam splitter body 1.

[0037] See Figure 2-Figure 5 A spring 5 is installed at the bottom of the interior of the cavity 4, and the top of the spring 5 is connected to the movable block 12. When the movable block 12 moves down, it will squeeze the spring 5, so that the spring 5 is compressed, which is convenient for pushing the movable block 12 to reset and move. The card column 6 is located inside the card hole 7, and the card column 6 is adapted to the card hole 7. When the card column 6 is inserted into the card hole 7, the mounting ear 10 can be limited and fixed, and the beam splitter body 1 can be installed. The card column 6 is slidably connected to the cavity 4 through the movable block 12. The outer wall of the movable block 12 contacts the inner wall of the cavity 4. When the movable block 12 slides inside the cavity 4, it drives the card column 6 to move, so that the card column 6 can move into the cavity 4.

[0038] See Figures 1-6 The number of mounting columns 2 is the same as the number of mounting holes 11. The mounting columns 2 pass through the mounting holes 11 so that the mounting columns 2 can pass through the mounting holes 11, thereby facilitating the installation of the beam splitter body 1. The beam splitter body 1 is detachably connected to the audio speaker plate 3, which facilitates the disassembly and assembly of the beam splitter body 1. The beam splitter body 1 is made of ABS plastic material, which improves the insulation performance of the beam splitter body 1 and can also improve the impact resistance of the beam splitter body 1.

[0039] Example 2:

[0040] On the basis of the above-mentioned embodiment 1, in order to facilitate the movable block 12 to move in the cavity 4 and compress the spring 5, the following structure is provided.

[0041] Specifically, a through groove 8 is provided on the outer surface of the mounting column 2, and a pressure plate 9 passing through the through groove 8 is connected to the outer surface of the movable block 12, so that the staff can press the pressure plate 9 to move the pressure plate 9 downward and drive the movable block 12 to move downward. A rubber pad is provided on the outer wall of the pressure plate 9, and the width of the pressure plate 9 is smaller than the width of the movable block 12. The pressure plate 9 is slidably connected to the through groove 8 so that the pressure plate 9 slides inside the through groove 8, thereby improving the stability of the pressure plate 9 when moving.

[0042] The working principle of the present invention is as follows: first, by installing a beam splitter device in front of the audio speaker plate 3 of the 3-inch speaker, it is used to collect high-frequency sound waves and separate mid- and low-frequency sound waves, so as to minimize the mutual mixing and interference of mid- and low-frequency sound waves and high-frequency sound waves, thereby improving the sound quality and timbre;

[0043] When installing the beam splitter body 1, the beam splitter body 1 is sleeved on the mounting column 2, and when sleeved, the pressure plate 9 can be pressed first, so that the pressure plate 9 drives the movable block 12 to move, and drives the clamping column 6 to move into the cavity 4, and then the beam splitter body 1 is moved so that the clamping hole 7 on the mounting ear 10 is aligned with the clamping column 6. At this time, the pressure plate 9 is no longer pressed, the spring 5 is stretched and then pushes the movable block 12 to reset and move, and the clamping column 6 to reset and move, so that the clamping column 6 is clamped into the clamping hole 7 and then the mounting ear 10 is locked and limited, and the installation of the beam splitter body 1 can be completed. When disassembling, only the pressure plate 9 needs to be pressed to make the clamping column 6 move out of the clamping hole 7 and no longer limit the mounting ear 10. In this way, the beam splitter body 1 can be removed. In this way, the beam splitter body 1 can be quickly disassembled and assembled.
