[0002] The sound beam is a special form of sound waves when they propagate in a medium. It is a collection of energy composed of countless sound wave vibrations. It is often used to describe the propagation and form of sound in space. The sound beam angle is the dispersion angle of the sound wave, and it affects whether the state of the sound beam is focused or diffuse, thereby affecting the propagation of sound. However, the sound-generating part of existing sound-generating devices is fixed, so the sound beam angle is also fixed and cannot be adjusted. Therefore, if there is a problem with the assembly and it needs to be adjusted or it needs to be adjusted later, it cannot be adjusted. Summary of the invention

[0007] The movable member is provided with a ball corresponding to each groove rail, and the ball moves in the groove rail. When the adjusting member rotates, the movable member moves up and down with the movement of the ball in the groove rail, thereby driving the connecting rod to move up and down and then driving the mounting frame to expand outward or contract inward.

[0008] Preferably, a connecting shaft is provided on the top of the connecting rod, and the connecting shaft and the connecting rod are vertically arranged, and the inner wall of each mounting frame is provided with groove 1 and groove 2 which are interconnected and perpendicular to each other, wherein groove 1 is used for the connecting rod to enter, and groove 2 is used for the connecting shaft to enter and rotate.

[0031] The groove rail 11 , the connecting rod 41 and the ball bearing 42 are in one-to-one correspondence with the mounting frame 2 .

[0032] Therefore, in actual use, through the setting of the adjusting member 1, when the adjusting member 1 rotates, the movable member 4 moves up and down with the movement of the ball 42 in the groove 11, thereby driving the connecting rod 41 to move up and down and then driving the mounting frame 2 to expand outward or contract inward. At this time, the sound beam angle will change with the movement of the mounting frame and can be adjusted.

[0033] The rotation of the adjusting member 1 can be controlled manually or by a motor, so an assembly plate 7 can be provided to connect with the motor. Meanwhile, the speaker 3 is a conventional small speaker, so the specific structure will not be described in detail here.
