In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0019] See also Figures 1 to 4 The three-way line array speaker of the utility model embodiment is characterized in that it includes a box body 1, a placement box 2 is arranged inside the box body 1, and a plurality of full-range card holes 21 and treble card holes 22 are arranged on one side of the placement box 2, the treble card holes 22 are arranged along the midline of the box body 1, and the full-range card holes 21 are symmetrically arranged on both sides of the treble card holes 22. Two placement plates 3 are also arranged inside the box body 1, and one end of the two placement plates 3 abuts to form a "V" shape, and the abutment of the two placement plates 3 is opposite to the treble card hole 22, and the placement plates 3 are provided with bass card holes 31, and the front and rear side covers of the box body 1 are provided with flat plates, and the left and right side covers of the box body 1 are provided with connecting plates 4, and the connecting plates 4 are provided with connecting structures 41.

[0020] In the above embodiment, the box 1 is used as the main body of the speaker, and a placement box 2 is provided inside for installing and fixing the treble audio and full-range audio components. One side of the placement box 2 is designed with a plurality of full-range card holes 21 and treble card holes 22. The treble card holes 22 are arranged along the midline of the box 1 to ensure that the emission of the treble is directional and consistent, while the full-range card holes 21 are symmetrically arranged on both sides of the treble card holes 22 to achieve uniform diffusion of full-range sound. Two placement plates 3 are also provided in the box 1, one end of which is abutted in a "V" shape. Such a design not only enhances the structural stability of the speaker, but also provides a suitable installation position for the woofer. The woofer card hole 31 on the placement plate 3 is used to fix the woofer. The front and rear side covers of the box 1 are provided with flat panels for protecting the components inside the speaker and reducing sound leakage. The left and right sides of the box 1 are covered with connecting plates 4, and the connecting plates 4 are provided with connecting structures 41 to facilitate the connection and fixation between the speakers. When two or more cabinets 1 are stacked by front and rear flat panels and connected and fixed by the connection structure 41 on the left and right connection plates 4, a hanging connection can be formed. Since the cabinet 1 has a built-in double placement plate 3, and the distances between the bass card hole 31 and the full-range card hole 21 are equal, when multiple cabinets 1 are hung and connected, the full-range card hole 21, the treble card hole 22 and the bass card hole 31 on each cabinet 1 can be located in a straight line, ensuring the same hanging ratio, thereby achieving linear propagation and coupling effects of sound.

[0021] See also Figures 1 to 4 In another embodiment, the tweeter hole 22 is in the shape of a rectangle, and its length is equal to that of the placement box 2.

[0022] In the above embodiment, the rectangular tweeter clip hole 22 can provide a larger installation space, which is convenient for fixing the tweeter. At the same time, the clip hole length is equal to the length of the placement box 2, which ensures that the position of the tweeter in the sound box is consistent with the length direction of the placement box 2, which is conducive to the uniform propagation of the tweeter sound waves in front of the sound box, and improves the focus and directionality of the sound.

[0023] See also Figures 1 to 4 In another embodiment, the full-range card hole 21 is in an octagonal shape.

[0024] In the above embodiment, the octagonal structure has more sides than other polygons such as a square or a circle while maintaining a certain area, so that the sound waves can be diffused more evenly when passing through the hole, reducing standing waves and reflections.

[0025] See also Figures 1 to 4 In another embodiment, the bass card hole 31 is circular in shape.

[0026] In the above embodiment, the circular holes can provide uniform spatial distribution, so that the woofer can better match the structure of the box 1 during installation, reducing obstruction and interference in the sound propagation process. Secondly, the edges of the circular holes are smooth, which helps to reduce the diffraction and scattering of sound, so that the bass can be propagated more concentratedly along the predetermined direction, improving the focus and consistency of the sound.

[0027] See also Figures 1 to 4 In another embodiment, the placement box 2 is further provided with a threaded hole 23 , and both ends of the abutment points of the two placement plates 3 are rounded and are opposite to the threaded hole 23 .

[0028] In the above embodiment, when the two placement plates 3 are butted together, the rounded corners at both ends of them just form a circular hole, and the position of this circular hole corresponds to the threaded hole 23 on the placement box 2. The threaded hole 23 is used to insert a threaded member (such as a screw) into the circular hole formed by the rounded corner, which can play a role in limiting. This design not only ensures the tight fit between the placement plates 3, but also prevents their relative movement or misalignment during use, ensuring that the abutment of the two placement plates 3 is always opposite to the position of the treble clamp hole 22.

[0029] See also Figures 1 to 4 In another embodiment, the box body 1 is further provided with a fixing plate 5 , and the fixing plate 5 is provided with a mounting groove 51 , and the mounting groove 51 is opposite to the tweeter card hole 22 .

[0030] In the above embodiment, the fixing plate 5 added to the box body 1 is provided with a mounting groove 51 , the position of which corresponds to the tweeter clamp hole 22 , and is used for mounting the woofer acoustic component.

[0031] See also Figures 1 to 4 In another embodiment, the connection structure 41 includes a connection sheet 411 and at least one connection hole 412, and the connection hole 412 is provided on the connection sheet 411 and the box body.

[0032] In the above embodiment, the design of the connection hole 412 allows bolts, screws or other fasteners to be passed through to tightly connect adjacent speaker boxes together. The connecting piece 411, as an intermediary, not only provides sufficient strength and stability to withstand the weight of the speaker and the tension during hanging, but also ensures the alignment accuracy of the connection hole 412, so that the connection between the speakers is both firm and accurate. When multiple speakers are hung and connected through the connection structure 41, the cooperation of the connection hole 412 and the connecting piece 411 ensures the straight line arrangement between the speakers, avoiding the misalignment or tilt caused by improper connection.

[0033] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
