Description
Technical Field
[0001] The utility model relates to the field of linear array sound boxes, in particular to a box structure of a linear array sound box. Background Art
[0002] The patent document with the Chinese patent authorization announcement number CN213152351U discloses a technical solution named "a linear array speaker with high-frequency superposition technology", which includes the following technical features: a box, a tweeter and two woofers, wherein the tweeter and the two woofers are installed side by side in the box, and the tweeter is located between the two woofers. Because the tweeter and the two woofers are set in the same closed inner cavity of the box (see the figure attached to its specification), the linear array speaker has a high frequency superposition technology. Figure 2 As we can see, the sound waves diffused backwards by each speaker are difficult to diffuse out of the box quickly. These sound waves will interfere with each other in the box, resulting in a significant reduction in sound quality, which will greatly affect the low-frequency performance of the linear array speaker. Therefore, it is necessary to redesign the box structure of the linear array speaker. Utility Model Content
[0003] The utility model aims to solve the above-mentioned problems and shortcomings and to provide a box structure of a linear array speaker. The box structure can greatly reduce the mutual interference of sound waves inside by reasonably arranging the internal space and reasonably setting the inverted tube, which can greatly improve the sound quality, thereby making the linear array speaker have a very good low-frequency performance rate, thereby achieving a greater sound pressure, widening the low-frequency dive and volume, and increasing the total output efficiency of the speaker; and the inverted tube is arranged on the side wall of the box, which can reduce the area of the front of the speaker relative to setting the inverted tube on the front of the speaker, thereby having less impact on the stage beauty.
[0004] The technical solution of the utility model is implemented as follows: a box structure of a linear array speaker, which is characterized in that it includes a box, and a left bass cavity, a treble cavity, and a right bass cavity are opened on the front wall of the box from left to right in sequence, and a left bass reflex tube and a right bass reflex tube connected to the left bass cavity and the right bass cavity are respectively arranged on the left and right side walls of the box.
[0005] Preferably, the left inverter tube and the right inverter tube are arranged in an "eight" relationship in a top view direction.
[0006] Preferably, the rear end of the left bass reflex tube is connected to the rear cavity wall of the left bass cavity.
[0007] Preferably, the rear end of the right bass reflex tube is connected to the rear cavity wall of the right bass cavity.
[0008] Preferably, the left inverter tube is arranged in an inclined state with a higher rear end and a lower front end.
[0009] Preferably, the right inverted tube is arranged in an inclined state with a higher rear end and a lower front end.
[0010] Preferably, an inner cavity is opened on the box body, and a surrounding plate is arranged on the middle part of the front cavity wall of the inner cavity, and the surrounding plate and the front wall of the inner cavity enclose a tweeter cavity, and a partition is arranged in the middle part of the inner cavity, and the partition divides the inner cavity into a left bass cavity and a right bass cavity.
[0011] Preferably, the left bass reflex tube is integrally formed on the left side wall of the box body.
[0012] Preferably, the right bass reflex tube is integrally formed on the right side wall of the box.
[0013] The beneficial effects of the utility model are as follows: in the box structure of the linear array speaker, a left bass cavity, a treble cavity, and a right bass cavity are sequentially opened on the front wall of the box from left to right, and a left inverted phase tube and a right inverted phase tube connected to the left bass cavity and the right bass cavity are respectively arranged on the left and right side walls of the box. The left bass cavity and the right bass cavity are used to install a bass speaker, and the treble cavity is used to install a tweeter, which can not only separate the bass and treble inside the linear array speaker, but also avoid mutual interference between the bass and treble inside the linear array speaker, and can use the left inverted phase tube and the right inverted phase tube to quickly derive sound waves, and superimpose with the front low frequency to achieve greater sound pressure. The box structure of the linear array speaker can greatly reduce the mutual interference of sound waves inside by reasonably arranging the internal space and reasonably setting the inverted tube, which can greatly improve the sound quality, so that the linear array sound has a very good low-frequency performance rate, and then can achieve greater sound pressure, widen the low-frequency dive and volume, and increase the total output efficiency of the sound. The box structure of the linear array speaker can be conducive to producing high-quality sound quality. In the box structure, the left inverted tube and the right inverted tube are respectively located on the left and right side walls of the box, which can reduce the area of the front of the speaker relative to setting the inverted tube on the front of the speaker. When the speaker needs a larger inverted tube for low frequency, the front area of most speakers with inverted tubes set on the front will be larger, which is inconvenient for transportation or use. The utility model can reduce the front area of the speaker by designing the inverted tube to be sideways, which not only makes the linear array speaker easy to transport and use, but also has less impact on the stage beauty.

[0016] Figure 3 It is a structural schematic diagram of the box structure in the right view direction of the utility model. Implementation
[0017] like Figures 1 to 3 As shown, the box structure of a linear array speaker described in the utility model includes a box 1, and a left bass cavity 11, a treble cavity 12, and a right bass cavity 13 are sequentially opened on the front wall of the box 1 from left to right, and a left bass reflex tube 2 and a right bass reflex tube 3 are respectively arranged on the left and right side walls of the box 1, and the left bass reflex tube 2 and the right bass reflex tube 3 are respectively connected to the left bass cavity 11 and the right bass cavity 13.
[0018] In the box structure of the linear array speaker, a left bass cavity 11, a treble cavity 12, and a right bass cavity 13 are sequentially opened on the front wall of the box 1 from left to right, and a left inverted phase tube 2 and a right inverted phase tube 3 connected to the left bass cavity 11 and the right bass cavity 13 are respectively arranged on the left and right side walls of the box 1. The left bass cavity 11 and the right bass cavity 13 are used to install a bass speaker, and the treble cavity 12 is used to install a tweeter, which can not only separate the bass and treble inside the linear array speaker, but also avoid mutual interference between the bass and treble inside the linear array speaker, and can use the left inverted phase tube 2 and the right inverted phase tube 3 to quickly derive sound waves, and superimpose with the front low frequency to achieve greater sound pressure. The cabinet structure of the linear array speaker can greatly reduce the mutual interference of sound waves inside by reasonably arranging the internal space and reasonably setting the inverted tube, which can greatly improve the sound quality, so that the linear array speaker has a very good low-frequency performance rate, and can achieve greater sound pressure, widen the low-frequency dive and volume, and increase the total output efficiency of the speaker. The cabinet structure of the linear array speaker can produce high-quality sound quality.
[0019] In the box structure, the left inverted tube 2 and the right inverted tube 3 are respectively located on the left and right side walls of the box 1, which can reduce the front area of the speaker relative to setting the inverted tube on the front of the speaker. When the speaker needs a larger inverted tube for low frequency, the front area of most speakers with inverted tubes on the front will be larger, which is inconvenient for transportation or use. However, the utility model can reduce the front area of the speaker by placing the inverted tube on the side through design, which not only makes the linear array speaker easier to transport and use, but also has less impact on the stage beauty.
[0020] like Figure 2 As shown, the left inverted phase tube 2 and the right inverted phase tube 3 are arranged in an "eight" relationship in the top view direction. In this way, the left inverted phase tube 2 and the right inverted phase tube 3 can both guide the sound waves forward, thereby achieving a very good effect of sound reinforcement, thereby greatly improving the sound quality of the speaker, which helps to further improve the reliability of the box structure.
[0021] like Figure 2 As shown, the rear end of the left bass reflex tube 2 is connected to the rear wall of the left bass cavity 11. In this way, the left bass reflex tube 2 can be restricted by the cavity wall of the left bass cavity 11, thereby reducing the vibration of the left bass reflex tube 2, and further enabling the left bass reflex tube 2 to have a better sound conduction effect, which helps to further improve the sound quality.
[0022] like Figure 2 As shown, the rear end of the left inverted phase tube 2 is embedded in the rear cavity wall of the left bass cavity 11. Such a connection structure is not only convenient for assembly, but also has a good limiting effect, thereby ensuring that the linear array speaker has a high sound quality output.
[0023] like Figure 2 As shown, the rear end of the right bass reflex tube 3 is connected to the rear wall of the right bass cavity 13. In this way, the right bass reflex tube 3 can be restricted by the cavity wall of the right bass cavity 13, thereby reducing the vibration of the right bass reflex tube 3, and further enabling the right bass reflex tube 3 to have a better sound guiding effect, which helps to further improve the sound quality.
[0024] like Figure 2 As shown, the rear end of the right inverted phase tube 3 is embedded in the rear cavity wall of the right bass cavity 13. Such a connection structure is not only convenient for assembly, but also has a good limiting effect, thereby ensuring that the linear array speaker has a high sound quality output.
[0025] like Figure 1 and Figure 2 As shown, the left inverted tube 2 is arranged in an inclined state with a high rear end and a low front end. Such a left inverted tube 2 can transmit sound waves forward and downward, so that it can transmit sound to the audience very well, and then the audience can receive better sound effects, which helps to further improve the reliability and applicability of the box structure.
[0026] like Figure 1 and Figure 2 As shown, the right inverted phase tube 3 is arranged in an inclined state with a high rear end and a low front end. Such a right inverted phase tube 3 can transmit sound waves forward and downward, so that it can transmit sound to the audience very well, and then the audience can receive better sound effects, which helps to further improve the reliability and applicability of the box structure.
[0027] like Figure 2As shown, the box body 1 is provided with an inner cavity 10, and a panel 14 is provided in the middle of the front wall of the inner cavity 10, and the panel 14 and the front wall of the inner cavity 10 enclose a tweeter cavity 12, and a partition 15 is provided in the middle of the inner cavity 10, and the partition 15 separates the inner cavity 10 into a left bass cavity 11 and a right bass cavity 13. Such an assembly structure is very simple and reliable, which is not only convenient for manufacturing, but also provides sufficient space for the left bass cavity 11 and the right bass cavity 13, so as to produce more reliable sound quality, and further help to further improve the reliability and applicability of the box structure of the linear array speaker.
[0028] At least one woofer is installed on the front cavity opening of the left bass cavity 11 and the right bass cavity 13 respectively, a horn is arranged on the front cavity opening of the tweeter cavity 12, a plurality of waveguides are connected to the inner port of the horn, and a tweeter is arranged on the inner port of each waveguide, so that a reliable and applicable linear array sound system can be obtained.
[0029] like Figure 2 As shown, the left inverted phase tube 2 is integrally formed on the left side wall of the box 1. This not only facilitates assembly, but also makes the box structure of the linear array speaker more stable and reliable, thereby helping the linear array speaker to maintain good performance for a long time.
[0030] like Figure 2 As shown, the right inverted phase tube 3 is integrally formed on the right side wall of the box 1. This not only facilitates assembly, but also makes the box structure of the linear array speaker more stable and reliable, thereby helping the linear array speaker to maintain good performance for a long time.
