DETAILED DESCRIPTION

[0020] The technical solutions of the utility model are further illustrated in the following with reference to the drawings and specific embodiments.

[0021] As shown in Figure 1 , Figure 2 , the embodiment of the utility model discloses a linear array sound box, including first sound box 100 and second sound box 200, the bottom of second sound box 200 is rotationally connected with the top of first sound box 100, when second sound box rotates and swings around the connecting part and the bottom leans on the top of first sound box, the sound emitting surfaces all face outward, and the second sound box is in the unfolded position, when the top of second sound box rotates and swings around the connecting part and leans on the bottom of first sound box, the two sound emitting surfaces are arranged close to each other, and the second sound box is in the storage position.

[0022] The linear array sound box described above has simple overall structure, can be folded and stored for adjustment when being carried and moved, reduces the vertical space position occupied by the second sound box, and can prevent collision and damage during carrying.

[0023] When in use, it can be quickly unfolded and used, and the operation is convenient, and the overall deformation adjustment structure is simple, and the missing situation of the split structure does not occur, so that the actual use and operation are facilitated, it should be noted that the first sound box and the second sound box can be electrically connected through the wire arrangement / spring wire at the rotating and swinging part, or can be electrically connected through the plug-in separable data line, so that the required power transmission and signal transmission can be met, and details are not described herein.

[0024] Further, as shown in Figure 3 , Figure 4 , the first sound box 100 is provided with a sink groove 110 at the top of the sound emitting surface, and the groove width of the sink groove is matched with the width of the second sound box, the two sides of the sink groove 110 close to the edge are provided with first round holes 120, the bottom of the second sound box 200 is fixedly provided with butt joint plates 210 on both sides, the butt joint plates 210 protrude towards the side of the sound emitting surface, and the protruding end is provided with second round holes 220, and the second sound box and the first sound box are rotationally connected through the bolts arranged in the second round holes and the first round holes, the designed sink groove can be used as the containing and placing part of the butt joint plate, especially the side away from the sound emitting surface, which can be used as the relying and supporting part of the second sound box after unfolding, so as to provide stable support and better maintain the required placement position, it should be noted that the rotating and connecting part includes but is not limited to the bolt connection, and can also be matched through the rotating shaft / pin, so as to provide the required rotating support effect.

[0025] Further, as shown in Figure 2As shown, washers 300 for increasing rotational friction are fitted on the bolts between the mating plate 210 and the wall of the settling tank 110. The washers include, but are not limited to, spring washers, rubber washers, etc., which can provide rotational friction and form a rotational damping feel.
