[0002] In a broad sense, audio refers to a device that uses electronic circuit design to convert audio and electronic signals. However, in general speaking, audio usually refers to a set of equipment that can restore and play audio signals. Audio equipment generally includes power amplifiers, peripheral equipment, speakers, mixers, etc. The development history of audio technology can be divided into four stages: electron tubes, transistors, integrated circuits, and field effect transistors. With the improvement of living standards, outdoor singing and dancing performances are often held outdoors, and outdoor audio is needed at this time. Traditional outdoor audio is powered by batteries and can be moved by rollers at the bottom to improve convenience during use.

[0003] Due to the large size of outdoor speakers, the speaker opening inside is also large. If it suddenly rains heavily when used outdoors, water will enter the speaker and affect its use. If a baffle is set on the front side of the speaker, it will affect the sound effect of the speaker. Utility Model Content

[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] Please refer to Figure 1 and Figure 2 As shown, a portable outdoor waterproof speaker comprises a speaker body 1, a roller 2 is symmetrically arranged on one side of the bottom of the speaker body 1, a telescopic pull rod 3 is vertically slidably installed on the upper side of the speaker body 1 close to the roller 2, so that when the speaker body 1 is pulled, the telescopic pull rod 3 can be pulled up for easy operation, and conversely, the telescopic pull rod 3 is moved down to keep the volume of the speaker small, a handle 4 is arranged on the upper surface of the speaker body 1 to improve the convenience when moving, an operation panel 5 is arranged on the front side of the upper surface of the speaker body 1, a protective convex ring 6 is arranged on the front side of the speaker body 1, and a speaker 7 is arranged inside the speaker body 1. The speaker 7 It is placed on the inner side of the protective convex ring 6, and a rotating frame 8 is rotatably installed on the outer side of the protective convex ring 6. The rotating axis of the rotating frame 8 is at the same height as the center of the protective convex ring 6. The rotating frame 8 is a U-shaped structure open downward. A rainproof cloth 9 is installed above the front surface of the audio body 1. The rainproof cloth 9 is placed above the protective convex ring 6, and the end of the rainproof cloth 9 facing away from the audio body 1 is connected to the rear side of the top rod of the rotating frame 8. When the rotating frame 8 is in a vertical state, the center of the rainproof cloth 9 is folded downward to prevent the rainproof cloth 9 from being pulled in a taut state when the rotating frame 8 is flipped forward. When the rainproof cloth 9 is taut, it is in a state of low front and high back.

[0021] Please refer to Figure 1-Figure 3As shown, convex blocks 10 are symmetrically arranged on the top of the rotating frame 8, and a fixing bolt 11 is arranged on the surface of one side of the convex block 10 close to the audio body 1, and a ball head 12 is arranged on the end of the fixing bolt 11. A limited groove 13 is arranged on the surface of the fixing bolt 11, and a cavity 17 is arranged on the front surface of the audio body 1, and the cavity 17 is placed above the rainproof cloth 9. Both sides of the cavity 17 are provided with mounting holes 14, and a sealing plate 18 is installed on the outside of the cavity 17 by bolts. Removing the sealing plate 18 can open the cavity 17 to facilitate the installation or removal of internal parts, and docking through holes 181 are symmetrically arranged on both sides of the surface of the sealing plate 18, and the docking through holes 181 correspond to the positions of the mounting holes 14. When the rotating frame 8 is in a vertical state, the fixing bolt 11 passes through the docking through holes 181 and is placed inside the mounting hole 14, and the fixing bolt 11 is adapted to the internal size of the mounting hole 14, and a moving block 16 is slidably installed inside the mounting hole 14, and the end of the ball head 12 contacts the moving block 16, and the ball head 12 can reduce friction.

[0022] Please refer to Figure 3 As shown, a spring A15 is designed inside the mounting hole 14, and the spring A15 contacts the rear surface of the moving block 16. The elastic force of the spring A15 allows the moving block 16 to be pushed by the fixing bolt 11 when the rotating frame 8 is in a vertical state so that the spring A15 accumulates force. When the fixing bolt 11 is restricted, the fixing bolt 11 can be pushed out by the accumulated force of the spring A15 to realize the outward rotation of the rotating frame 8, and when the moving block 16 is pushed to move, it cannot exceed the wedge-shaped slider 20 to prevent it from falling off.

[0023] Among them, slide grooves 19 are symmetrically opened on both sides of the lower surface of the cavity 17, and the slide grooves 19 are vertically arranged to the mounting hole 14. A wedge-shaped slider 20 is slidably installed inside the slide groove 19, and the end of the wedge-shaped slider 20 is adapted to the internal size of the limiting groove 13 to limit the fixing bolt 11 so that the rotating frame 8 remains stable when it is in a vertical state. A spring B21 is arranged inside the slide groove 19, and one end of the spring B21 is in contact with the wedge-shaped slider 20 so that the wedge-shaped slider 20 is always subjected to an outward force, so that it can be self-locking after the fixing bolt 11 is inserted into the mounting hole 14.

[0024] Please refer to Figure 1-Figure 3 As shown, a knob 23 is rotatably installed at the center of the surface of the sealing plate 18, and the ends of the two wedge-shaped sliders 20 facing away from the mounting hole 14 are connected to pull ropes 22, and the pull ropes 22 pass through the spring B21. The ends of the two pull ropes 22 facing away from the wedge-shaped sliders 20 are connected to the ends of the knob 23, so that the pull ropes 22 can be pulled simultaneously from the outside, so that the wedge-shaped sliders 20 on both sides slide inward at the same time, and no longer limit the fixing bolt 11.

[0025] The working principle of the utility model is as follows: when in use, the telescopic pull rod 3 can be lifted up and then pulled, at which time the whole body 1 of the sound system can be tilted, so that the movement of the body 1 of the sound system can be realized through the roller 2 at the bottom, and the rotating frame 8 can be pushed to a vertical state in sunny weather, and the center of the rainproof cloth 9 is folded downward, at which time the fixing bolt 11 passes through the docking through hole 181 and enters the inside of the mounting hole 14, and squeezes the moving block 16, at which time the spring A15 is in a power storage state, and at the same time, due to the existence of the spring B21, the wedge-shaped slider 20 always has an outward force, and the end of the wedge-shaped slider 20 cooperates with the limiting groove 13 The position of the fixing bolt 11 is kept fixed. At this time, the pull ropes 22 on both sides are in a taut state. When encountering rainy weather, the pull ropes 22 on both sides can be pulled simultaneously by rotating the knob 23 externally, and then the wedge-shaped slider 20 is pulled to move inside the slide groove 19, and no longer cooperates with the limiting groove 13. At this time, the fixed bolt 11 can be ejected by using the stored force of the spring A15, so that the fixed bolt 11 has an outward thrust, and then the top of the rotating frame 8 rotates slightly forward, and then the rotating frame 8 continues to rotate due to its own weight, and the rotating frame 8 continues to rotate until the rainproof cloth 9 is in a taut state to form a rain shelter on the top of the speaker 7.

[0026] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the art unless otherwise specified or limited.
