Therefore, they cannot be understood as limitations on the present invention.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 , an outdoor megaphone with good placement stability, including an outdoor megaphone body 1, two support seats 2 are rotatably connected on the left and right side walls near the lower end of the outdoor megaphone body 1, and tapered slots 3 are provided on the opposite side walls of the two support seats 2. The two support seats 2 are horizontally rotated on the opposite side walls near the outdoor megaphone body 1 and are penetrated by a rotating shaft 4. The two rotating shafts 4 are fixedly connected with a connecting block 5, and the same U-shaped supporting block 6 is provided between the two connecting blocks 5. The U-shaped supporting block 6 is inserted in the tapered slot 3 and contacts with its inner wall. The upper ends of the vertical sections on both sides of the U-shaped supporting block 6 are provided with rectangular slots 7, and the lower ends of the two connecting blocks 5 are respectively inserted in the two rectangular slots 7. Manually rotate the supporting seats 2 on both sides to contact the placement surface, rotate the U-shaped supporting block 6 to cooperate with the connecting block 5 and the rotating shaft 4 to rotate, and twist the rectangular The bolts 9 on the protrusions 8 adjust the relative distance between the connecting block 5 and the U-shaped support block 6 until the U-shaped support block 6 contacts the placement surface, and then tighten the bolts 9 again to position it, so that the support seats 2 on both sides cooperate with the U-shaped support block 6 to provide stable support for the outdoor loudspeaker body 1 to prevent accidental impact or wind from causing tipping, ensuring the sound amplification effect. Rectangular protrusions 8 are provided on the opposite side walls of the vertical sections on both sides of the U-shaped support block 6. The upper ends of the two rectangular protrusions 8 are on the same horizontal plane as the upper ends of the vertical sections of the U-shaped support block 6. Bolts 9 are threaded through the two rectangular protrusions 8. The bolts 9 are used to press the connecting block 5 into position. The two bolts 9 are respectively arranged horizontally through the inner walls of the two rectangular slots 7. The two bolts 9 are respectively pressed against the side walls of the two connecting blocks 5, and the rectangular protrusions 8 and the U-shaped support block 6 are integrated into a molding arrangement.
