Description

Technical Field

[0001] The utility model relates to the technical field of line array sound boxes, in particular to a line array sound box. Background Art

[0002] Line array speakers are sound source radiation units that are arranged in a straight line with close spacing. Multiple speakers have the same amplitude and phase. The coverage angles of multiple speakers are different. Line array speakers can provide very good vertical coverage directivity, making line array speakers suitable for long-distance sound radiation.

[0003] Line array speakers (for far field) are different from ordinary speakers (for near field). Line array speakers are mainly used in large occasions such as large-scale mobile performances, stadiums or large theaters. In the sound arrangement of application scenarios, the current conventional practice is to hang a separate group of line arrays for the main speakers to cover the far field and near field in front; and hang a separate group of line arrays for the side fill speakers to cover the inner field (or place front fill speakers at the stage lip to cover the inner field); this method requires more speaker models and quantities, and the side fill speakers need to be hung separately, the wires and power amplifier cabinets must be connected independently, and the manpower and financial resources consumed will also increase, so it needs to be improved on this basis.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention pertains. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] Please refer to Figure 1-4 The line array speaker provided by the utility model has a main expansion unit and a side supplement unit arranged in the shell 1 (i.e., an integrated structure is adopted). Compared with the traditional technology in which the main expansion speaker and the side supplement speaker need to be arranged separately, the structure is simpler, the installation is more convenient, and the cost is lower.

[0027] Please refer to Figure 2 In a preferred embodiment, the side supplement unit also includes a second midrange module, one end of the second midrange module is connected to the first midrange module 22, and the other end is tilted outward relative to the first midrange module 22.

[0028] Please refer to Figure 2 In a preferred embodiment, the second midrange module includes a first midrange unit 24 and a second midrange unit 25. One end of the first midrange unit 24 is connected to the first midrange module 22, and the other end is connected to the second midrange unit 25. The first midrange unit 24 is tilted outward relative to the first midrange module 22, and the second midrange unit 25 is tilted outward relative to the first midrange unit 24.

[0029] Please refer to Figure 2 In a further preferred embodiment, the side compensation unit includes a second midrange module and a second tweeter module 23 and an adjustment mechanism that are interconnected. The adjustment mechanism is also connected to the housing 1, and the adjustment mechanism can control the second tweeter module 23 to be close to or away from the second midrange module.

[0030] In the above three embodiments, the second midrange module is at least one midrange unit. The second midrange module is tilted upward relative to the first midrange module 22 to achieve the connection and coordination between the midrange and the treble. The tilt angle of the second midrange module is 10-90°, preferably 30-60° or 30° or 60°.

[0031] When the second midrange module is two midrange units (i.e., as listed in the second embodiment above), the first midrange unit 24 is inclined at an angle of 1-45° relative to the first midrange module 22, preferably 30°, the second midrange unit 25 is inclined at an angle of 1-45° relative to the first midrange unit 24, preferably 15°, or the second midrange unit 25 is inclined at an angle of 1-45° relative to the first midrange module 22, preferably 45°, wherein the first midrange module 22 is parallel to the horizontal plane, such as Figure 2 , the first midrange module 22 and the bottom plate 14 are arranged in parallel (the angle is 0 or 180°), that is, the angles between the first midrange module 22, the first midrange unit 24 and the second midrange unit 25 are gradually changed to 0, 30, and 45°, so as to achieve connection with the second tweeter module 23 (connection between treble and midrange);

[0032] In a further preferred embodiment, the first midrange unit 24 can be located in the same cavity with the first midrange module 22, and the first midrange unit 24 can also be located in the same cavity with the second midrange unit 25.

[0034] In a preferred embodiment, the distance between the second tweeter module 23 and the second midrange module is controlled by an adjustment mechanism to achieve an ultra-wide horizontal directivity of 140°. Compared with the traditional speakers that require two different speakers (i.e., the main amplifier and the side-fill speaker are used together), this embodiment only requires a single speaker to achieve the functions of the traditional two groups (two speakers of different specifications), which ensures the use of the internal space of the speaker to a certain extent. At the same time, it has significant advantages over traditional speakers in terms of manual installation and equipment costs. The adjustment of the second tweeter module 23 is mainly for adjusting the vertical angle of the side-fill unit on the one hand, and for adjusting the angle compensation after the array is bent in the horizontal direction on the other hand.
