The core acoustic components, based on the strong sound transducer technology, feature strong sound, directional, high-definition and long-range amplification effects. Their technical indicators have reached the international advanced and domestic leading levels.

Supports multi-platform deployment including portable, mobile and fixed types, and has the capabilities of multi-modal integration and "integrated detection and strike". In extremely dangerous special occasions, it can also be customized to be equipped with lethal weapon functions such as laser burning, enhancing the perimeter security prevention capability

It has surpassed similar imported equipment in key indicators such as peak sound pressure level and directivity, reaching the world's leading level, It is a representative of core technical capabilities.

With this transducer as the core and combined with AI algorithms, it can integrate perception methods such as radar, infrared, and thermal imaging to form an "acoustic defense +" integrated unmanned platform. At the same time, it supports the development of equipment towards being lighter, smaller and more portable, and is suitable for scenarios such as the daily use of individual police officers and the carrying of drones
