[0042] The lithium battery 5 is used to power the motor air pump 2.
[0043] The motor air pump 2, as the core power component, is installed inside the housing 1. Its function is to convert the electrical energy of the lithium battery 5 into mechanical energy to generate high-pressure gas, providing a power source for the high-intensity sound output of the speaker body 3. Compared with the traditional electromagnetic drive, the high-pressure gas drive method can break through the electromagnetic power limitation and significantly improve the sound intensity.
[0044] The air duct 4 connects the motor air pump 2 and the two speaker bodies 3. Its function is to deliver high-pressure gas to the sound-producing end without loss. The two speaker bodies 3 are symmetrically distributed on both sides of the motor air pump 2, which can form a stereo sound effect and expand the sound coverage range.
[0045] The lithium battery 5 is installed at the bottom of the housing 1 to provide stable power to the motor air pump 2. Its portability allows the speaker to be used without a fixed power source, making it suitable for outdoor and mobile scenarios. The switch 6 is located on one side of the housing 1, which can quickly cut off or connect the circuit to achieve real-time control of the speaker's working status.
[0046] The working principle of the loudspeaker provided by this utility model is as follows:
[0047] When in use, when the switch 6 on one side of the housing 1 is turned on, the lithium battery 5 and the motor air pump 2 form a circuit, and the lithium battery 5 provides power to the motor air pump 2.
[0048] Motor-driven air pump 2 starts up under electric power, generating high-pressure gas;
[0049] High-pressure gas is precisely delivered into the two horn bodies 3 through the air guide pipe 4 located between the motor pump 2 and the two horn bodies 3;
[0050] High-pressure gas pushes the sound-producing components to vibrate inside the speaker body 3, thereby producing a high-intensity whistle sound.
[0051] Compared with related technologies, the speaker provided by this utility model has the following beneficial effects:
[0052] This utility model provides a loudspeaker that generates high-pressure gas through a motor-pump 2 and delivers it precisely to two loudspeaker bodies 3 through an air guide tube 4.

It is suitable for long-distance warning or wide-area sound coverage scenarios.
[0053] The motor pump 2 is powered by a lithium battery 5, which eliminates the limitation of wired power supply. The working status can be flexibly controlled by the switch 6 on one side of the housing 1, making it convenient for use in mobile scenarios.
[0054] Second Embodiment
[0055] Please refer to the following: Figure 6 and Figure 7 Based on the loudspeaker provided in the first embodiment of this application, the second embodiment of this application proposes another loudspeaker. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0056] Specifically, the second embodiment of this application provides a different type of loudspeaker, wherein a dustproof component 7 is provided on one side of the loudspeaker body 3.

[0057] The plurality of bolts 73 are respectively disposed between the plurality of arc-shaped blocks 72 and the horn body 1.
[0058] The dustproof mesh 71 is used to reduce dust from entering the interior of the speaker body 3.
[0059] In the dustproof component 7 on one side of the speaker body 3, the dustproof net 71 blocks external dust from entering the speaker body 3. The arc-shaped block 72 and the bolt 73 firmly fix the dustproof net 71, ensuring the dustproof effect while facilitating later disassembly and maintenance.
[0060] The dustproof component 7 is a key structure to ensure the long-term reliable operation of the speaker. The dustproof mesh 71 covers the sound-emitting end of the speaker body 3, directly blocking dust from entering. The arc-shaped block 72 connects to the side of the dustproof mesh 71 and is fixed to the speaker body 3 by bolts 73. This detachable structure not only ensures the stability of the dustproof mesh 71, but also makes it convenient for users to disassemble and clean it regularly, avoiding the dustproof mesh from clogging and affecting sound transmission.
[0061] Compared with related technologies, the speaker provided by this utility model has the following beneficial effects:
[0062] This utility model provides a loudspeaker with a dustproof component 7 on one side of the loudspeaker body 3. The dustproof mesh 71 can effectively reduce the entry of dust into the loudspeaker body 3, and prevent the sound-producing components from degrading due to dust wear. At the same time, the dustproof component 7 is fixed to the loudspeaker body 3 by the arc-shaped block 72 and the bolt 73, which facilitates the disassembly and cleaning of the dustproof mesh 71, and further ensures the long-term reliability of the loudspeaker.
