DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution: a loudspeaker with adjustable sound output angle, comprising: a mounting frame 8 which is a cavity with openings at both ends, and a rectangular metal tube; an adjustment component is placed in the mounting frame 8, and the adjustment component comprises a shell 2, and a transverse adjustment track 4 is arranged on the outer side of the shell 2 through a rotating shaft 3, and a longitudinal adjustment track 6 is fixedly connected to the transverse adjustment track 4 on the outer side of the shell 2, and is used to adjust the transverse and longitudinal angles of the loudspeaker; a loudspeaker body 1 is placed inside the shell 2; a limiting nail 12 is threadedly connected to the outer side of the mounting frame 8, and the limiting nail 12 comprises a limiting plug plate 15, which is used to squeeze and lock the transverse adjustment track 4 and the longitudinal adjustment track 6.

[0025] It should be noted that the shell 2 of the utility model is a spherical structure, and the longitudinal adjustment track 6 is an arc structure and fits with the outer side of the shell 2. During installation, when the angle of the speaker body 1 is adjusted as needed, the transverse adjustment track 4 is first rotated laterally. The transverse adjustment track 4 and the No. 1 limit groove 9 and the No. 2 limit groove 11 are interference fit, so that the transverse adjustment track 4 rotates inside the No. 1 limit groove 9 and the No. 2 limit groove 11. After reaching the appropriate angle, tighten the limit pins 12 located on the side so that the limit plug plate 15 is inserted into the corresponding transverse limit groove 5 to fix the angle, and then turn to the shell 2 so that the shell 2 rotates around the rotating shaft 3. When the elevation adjustment of the speaker body 1 is completed, the limit pins 12 are tightened from the top, and the limit plug plate 15 is inserted into the longitudinal limit groove 7 for fixation, and then the gap between the shell 2 and the mounting frame 8 is filled with sealant to increase the stability of the overall structure.

[0026] like Figure 2 , 3 As shown in , 4, both ends of the shell 2 in the horizontal direction are fixedly connected with a rotating shaft 3, the rotating shaft 3 is rotatably connected to the transverse adjustment track 4, a No. 1 limit groove 9 is opened inside the mounting frame 8, the transverse adjustment track 4 is clamped in the No. 1 limit groove 9 and is slidably connected to the No. 1 limit groove 9, one end of the mounting frame 8 is fixedly connected to the limiting column 10, the middle part of the limiting column 10 is opened with a No. 2 limit groove 11, and the transverse adjustment track 4 is clamped in the No. 2 limit groove 11 and rotates.

[0027] It should be noted that one end of the utility model's No. 1 limit groove 9 is in a closed state. Under the blocking action of the limit column 10, the lateral adjustment track 4 is limited in the mounting frame 8 to prevent the mounting frame 8 from being separated from the lateral adjustment track 4. The angle adjustment of the speaker body 1 is achieved by rotating the lateral adjustment track 4 inside the mounting frame 8. The lateral adjustment track 4 is stuck in the No. 1 limit groove 9 and the No. 2 limit groove 11 to ensure that the lateral adjustment track 4 can only rotate horizontally to prevent the angle from shifting.

[0028] like Figure 1 , 5 As shown, transverse limit grooves 5 are equidistantly provided on the outer side of the transverse adjustment track 4, and longitudinal limit grooves 7 are equidistantly provided on the outer side of the longitudinal adjustment track 6. Limit pins 12 are installed on the top and sides of the mounting frame 8. The limit pins 12 are located at positions corresponding to the transverse adjustment track 4 and the longitudinal adjustment track 6. The limit pins 12 also include an adjusting screw 13. The bottom of the adjusting screw 13 is rotatably connected to the limit plug plate 15. The adjusting screw 13 is threadedly connected to the mounting frame 8. The top of the limit plug plate 15 is fixedly connected to the limit rod 16, and the limit rod 16 is slidably connected to the mounting frame 8.

[0029] It should be noted that the limit pins 12 of the utility model correspond to the position of the center of the shell 2, and the adjustment screw 13 is rotatably connected with the limit plug plate 15. After adjusting the angle of the lateral adjustment track 4, tighten the adjustment screw 13 to squeeze the limit plug plate 15, and the limit plug plate 15 is inserted into the corresponding lateral limit groove 5. When the position of the longitudinal adjustment track 6 is adjusted, the shell 2 rotates around the rotating shaft 3. After the angle is adjusted, the adjustment screw 13 located at the top is rotated so that the limit plug plate 15 is pressed tightly against the longitudinal limit groove 7, thereby fixing the elevation angle of the speaker body 1.

[0030] like Figure 1 , 3 As shown, four corners of the mounting frame 8 are provided with mounting holes 14 .

[0031] It should be noted that, in the present invention, the mounting frame 8 is fixed at the mounting position by means of mounting screws passing through the mounting holes 14 .
