[0033] Please refer to Figures 1 to 4 The present application provides a connector for hanging a line array speaker, including a connector body 10, a convex connecting rod 30 and a concave connecting rod 40.

[0034] Specifically, a cavity 20 is defined inside the connector body 10, and a first limiting column 110 and a second limiting column 130 are arranged in the cavity 20 at intervals, and a plurality of through holes penetrating the cavity 20 are arranged on the connector body 10, and a first opening and a second opening communicating with the cavity 20 are respectively arranged at both ends of the connector body 10. The convex connecting rod 30 is retractably extended into the cavity 20 from the first opening, and an abutting portion 30a is arranged on the convex connecting rod 30, and a first elastic member 100 is arranged between the abutting portion 30a and the first limiting column 110, and both ends of the first elastic member 100 are respectively connected to the abutting portion 30a and the first limiting column 110. The second opening of the concave connecting rod 40 can be telescopically extended into the cavity 20, and a recessed position 40a is provided at one end of the concave connecting rod 40 facing the convex connecting rod 30, and a second elastic member 120 is provided at the recessed position 40a, one end of the elastic member abuts against the second limiting column 130, and the other end of the second elastic member 120 abuts against the inner bottom of the recessed position 40a.

[0035] It should be noted that the “multiple” mentioned above refers to two or more than two, and the specific needs shall be determined according to the actual situation and are not limited to this.

[0036] The connecting piece for hanging a line array speaker based on the above technical features forms a cavity 20 by defining it inside the connecting body, and then the convex connecting rod 30 and the concave connecting rod 40 are retractably received in the cavity from the first opening and the second opening respectively. When the angle of the array speaker needs to be adjusted, it is only necessary to adjust the length of the convex connecting rod 30 and the concave connecting rod 40 extending from the cavity 20 to achieve the angle adjustment of the array speaker. The structure is simple and can be installed without multiple people. The array speaker can be quickly disassembled and assembled, thereby improving the installation efficiency. In addition, the first elastic member 100 and the second elastic member 120 are respectively provided to provide a certain buffering effect to the convex connecting member and the concave connecting member, thereby facilitating the fine adjustment of the convex connecting member and the concave connecting member, and the adjustment is more accurate, thereby meeting the requirements of the line array speaker for different installation angles.

[0037] In a possible implementation, the connector body 10 includes a first partition plate 11 and a second partition plate 12 , and the first partition plate 11 and the second partition plate 12 are connected to form a cavity 20 .

[0038] In a possible implementation, the distance between the first baffle 11 and the second baffle 12 is greater than the thickness of the convex connecting rod 30 and the concave connecting rod 40. In this way, it can be ensured that the convex connecting rod 30 and the concave connecting rod 40 can be retractably accommodated in the cavity 20, avoiding the situation where the first baffle 11 and the second baffle 12 cannot be retracted due to the distance between them being too small.

[0039] In a possible embodiment, a fastener 90 is further included, a first mounting hole is provided on the first partition 11, a second mounting hole aligned with the first mounting hole is provided on the second partition 12, and the fastener 90 is sequentially passed through the first mounting hole and the second mounting hole to connect the first partition 11 and the second partition 12. In this way, when the first partition 11 and the second partition 12 are spaced apart and the first mounting hole and the second mounting hole are aligned, the fastener 90 is sequentially passed through the first mounting hole and the second mounting hole to realize the detachable connection of the first partition 11 and the second partition 12, which is convenient for subsequent maintenance or replacement.

[0040] In one possible embodiment, a first adjustment hole 30b is provided on the convex connecting rod 30, and a plurality of first fixing holes 70 penetrating the connecting member body 10 are provided at intervals on the connecting member body 10, and the first fixing hole 70 is adapted to the first adjustment hole 30b; and / or a second adjustment hole 40b is provided on the concave connecting rod 40, and a plurality of second fixing holes 80 penetrating the connecting member body 10 are provided at intervals on the connecting member body 10, and the second fixing hole 80 is adapted to the second adjustment hole 40b.

[0041] In a possible embodiment, it also includes a first locking member 50 and a second locking member 60; when the convex connecting rod 30 is adjusted to a suitable position, the first locking member 50 is configured to lock the convex connecting rod 30 through the first adjustment hole 30b and the corresponding first fixing hole 70; when the concave connecting rod 40 is adjusted to a suitable position, the second locking member 60 is configured to lock the concave connecting rod 40 through the second adjustment hole 40b and the corresponding second fixing hole 80.

[0042] In a possible embodiment, the first locking member 50 and the second locking member 60 both include a screw and a stud, a nut is provided at one end of the screw, an external thread is provided at the other end of the screw, and a locking cavity is provided on the stud, and an internal thread matching the external thread is provided in the locking cavity.

[0043] It should be noted that, since the first locking member 50 and the second locking member 60 in this embodiment both adopt the same structure, the locking of the convex connecting rod 30 is taken as an example for description, as follows:

[0044] After the convex connecting rod 30 or the concave connecting rod 40 is adjusted to a suitable position, a screw is used to pass through the first adjustment hole 30b and the first fixing hole 70 from one side of the connector body 10, and then a locking column is sleeved on the screw and tightened so that the locking column abuts against the surface of the connector body 10, thereby locking the convex connecting rod 30; when the convex connecting rod 30 needs to be extended from the cavity 20, the locking column only needs to be unscrewed from the screw and the screw is taken out. After the convex connecting rod 30 is extended to a suitable position, the screw is extended from the corresponding first fixing hole 70 into the cavity 20, through the first adjustment hole 30b and out, and finally locked with the locking column. The structure is simple and the adjustment is convenient.

[0045] In a possible implementation manner, the first elastic member 100 and the second elastic member 120 are both springs.

[0046] In a second aspect, the present application further provides a line array speaker, comprising the connecting piece for hanging the line array speaker described in the first aspect.

[0047] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model.
