Description

Technical Field

[0001] The utility model relates to the field of loudspeaker fixing, and more specifically, to a loudspeaker multi-angle fixing device. Background Art

[0002] The sound produced by teachers when teaching is limited, but the space of the classroom is large. The sound gradually weakens as the propagation distance increases in the classroom, and it often needs to be enhanced by a loudspeaker so that students in the back row of the classroom can clearly hear the teacher's lecture. Existing loudspeakers often have built-in speakers in the box and external headphones. The sound is received by the headphones, enhanced by the power amplifier circuit inside the box, and then released through the speakers.

[0003] Chinese patent authorization announcement number: CN218679389U, provides a loudspeaker. This patent provides a loudspeaker. When placing the loudspeaker in different locations, the two flaps are flipped outward by hand until the two flaps are flattened, and then the two suction cups are attached to the plane by hand. The two flaps are tightened by the two suction cups respectively, so that the loudspeaker can be supported in the horizontal and vertical directions, and the flaps and suction cups are conveniently taken out to fix the loudspeaker. Conversely, when taking the loudspeaker, the suction cups are unplugged, the two flaps are flipped and immersed in the storage slots, and the two flaps are tightened and locked by the locking mechanism. The flaps and suction cups can also be flipped for storage and carrying, without the need to set up additional support components, so as to quickly fix the loudspeaker in different locations and reduce damage to the loudspeaker caused by tilting.

[0004] The above-mentioned loudspeaker is supported and fixed by arranging a flap and a suction cup at the bottom, but the loudspeaker cannot move after being positioned. During the teaching process, the teacher may need to adjust the use angle of the loudspeaker according to the installation position of the loudspeaker, which makes the use of the above-mentioned loudspeaker inconvenient.
