The air pump cooperates with the first piston ring and the second piston ring to perform inflation and deflation actions in the first piston chamber and the second piston chamber. When the air pump inflates, the fixed sleeve slides and rises, and the waterproof horn rises. When the air pump deflates, the fixed sleeve slides and descends, and the waterproof horn descends. At the same time, the moisture accumulated on the first piston ring is discharged, ensuring that moisture will not enter the interior of the speaker from the gap of the lifting structure, avoiding the situation where the internal wiring of the speaker is damp, and achieving a better moisture-proof effect of the lawn speaker.

[0020] 2. In the utility model, when the second piston chamber is deflated by the air pump, the fixed sleeve slides downward along the second piston chamber, so that the water accidentally entering the second piston chamber is pressed back to the first piston chamber, ensuring that the moisture-proof effect of the lifting lawn speaker is more effective.

[0029] The inner shell 7 is provided with an air hole 12, and the air pump 4 is connected to the second piston chamber 10 through the air hole 12. The air pump 4 acts on the second piston chamber 10 through the air hole 12, and the air pressure in the second piston chamber 10 changes, causing the fixed sleeve 2 to slide along the second piston chamber 10;

[0030] A transition chamber 13 is formed between the fixing sleeve 2 and the inner lining 8. The bottom of the outer shell 1 and the partition 11 are both provided with wiring holes 15 connected to the transition chamber 13. The transition chamber 13 is relatively sealed and is used to store the wiring and control circuits of the audio system.

[0031] The first piston ring 5 is located above the air pump 4, and the outer wall and inner wall of the first piston ring 5 are respectively in contact with the inner wall of the outer shell 1 and the outer wall of the inner shell 7, and the first piston ring 5 is tightly fitted to ensure the sealing of the first piston chamber 9;

[0032] The second piston ring 6 is located above the air hole 12, and the outer wall and inner wall of the second piston ring 6 are respectively in contact with the inner wall of the inner housing 7 and the outer wall of the liner 8, and the second piston ring 6 is tightly in contact with each other to ensure the sealing of the second piston chamber 10;

[0034] The waterproof speaker 3 is provided with a plurality of control buttons 14 , which are electrically connected to the air pump 4 , so as to conveniently control the operation status of the air pump 4 and ensure the normal rise and fall of the speaker.

[0035] Working principle: First, click the control button 14 to connect the air pump 4 to start the inflation work, the gas in the first piston chamber 9 decreases, the first piston ring 5 drops under the action of negative pressure, and the gas in the second piston chamber 10 increases, so that the fixed sleeve 2 slides upward along the second piston chamber 10, and the waterproof speaker 3 is lifted upward together with the fixed sleeve 2. During the whole process, the first piston ring 5 and the second piston ring 6 ensure the sealing of the first piston chamber 9 and the second piston chamber 10, ensuring that moisture will not easily enter the first piston chamber 9. Secondly, during use, if moisture accidentally enters the second piston chamber 10 through the first piston chamber 9, the air pump 4 deflates the second piston chamber 10 when it works again. At this time, the fixed sleeve 2 slides downward along the second piston chamber 10, so that the moisture entering the second piston chamber 10 is pressed back to the first piston chamber 9, thereby achieving that the internal wiring and equipment of the audio in the transition chamber 13 will not be affected by moisture, ensuring that the moisture-proof effect of the lifting lawn audio is more effective.
