The large speaker has an extremely loud volume with strong penetration power. It is waterproof and shock-resistant. It comes with a fixed bracket and the wiring is simple. It is specially designed for modifying warning devices on patrol and freight vehicles.

The speaker features a large-diameter and thickened amplification cavity, with a built-in high-power sound-emitting component. It outputs a loud and rich sound, capable of quickly achieving a warning and alerting effect in noisy environments such as busy streets, construction sites, and factory areas. The sound wave has a long propagation distance and a prominent warning effect. It is paired with a handheld wired microphone risk control device. The spiral retractable cable is convenient to store and does not get tangled. The panel has multiple color function buttons, allowing for a quick switch between seven different alarm sound tones, including long continuous sound, urgent siren, and variable pitch sounds. It can freely switch between high and low pitches. It is suitable for different scenarios and warning needs.12V Seven-tone Car Alarm Horn for Motorcycles and Electric Bicycles, Universal for Vehicle Modification with High-Pitched Warning Sirens
This 12V multi-functional alarm horn is compatible with various 12V vehicles such as cars, motorcycles, and electric tricycles. It integrates seven warning sound effects and a handheld shouting function. The large-diameter speaker has a loud and powerful sound volume with strong penetration, and can clearly transmit sound over long distances in outdoor areas. It is suitable for vehicle modification, engineering patrols, and property duty operations, and can fulfill both warning and shouting functions.
Noise reduction microphone, real-time shouting without getting out of the vehicle
The surface of the microphone is equipped with a fine metal sound pickup mesh cover, which effectively reduces wind noise interference during driving. By long-pressing the corresponding button, real-time amplification and shouting can be achieved.
