MP120 Digital Voice Broadcasting System
📢 Leading the Future of Sound: The MP120 integrates broadcasting, sound pick-up, and flashing lights into one compact yet powerful device. Designed for DJI Mavic 3 Enterprise, it delivers exceptional audio performance with enhanced visibility and intelligent automation.
Product Overview
The MP120 Digital Voice Broadcasting System is a highly integrated 300m drone loudspeaker system designed to meet the demanding needs of modern aerial operations. Weighing less than 130g, it adds minimal weight to the platform while offering a long 300m broadcasting distance. Its sophisticated communication link supports both DJI drone link and LTE link, ensuring stable and uninterrupted transmission of voice commands even in complex environments.
Beyond broadcasting, the MP120 excels at drone ground dialogue and monitoring. Equipped with a highly sensitive microphone, it provides a 5-meter ground listening range, allowing operators to capture real-time audio from the ground. This two-way audio communication drone capability transforms the MP120 Digital Voice Broadcasting System into a critical tool for search & rescue missions, crowd management, and tactical law enforcement, providing unmatched situational awareness from above.
Key Features
- High Sound Pressure Broadcasting: Delivers powerful audio with a broadcasting distance of ≥300 meters and sound pressure of ≥114dB, ensuring your message is heard clearly over vast areas.
- Broadcasting Monitoring: The built-in microphone provides real-time feedback of the broadcasted sound to the ground operator. This 300m drone loudspeaker system allows you to confirm broadcasting effectiveness even when the drone is flying beyond the effective broadcasting distance, ensuring mission-critical messages are delivered as intended.
- Transparent Horn with Flashing Lights: The horn tube is made of semi-transparent, light-guiding material that increases visibility at night. It features three flashing light modes (red & blue flashing, red flashing, blue flashing) to enhance situational awareness and safety during dusk or nighttime operations.
- AI Scene Broadcasting: This intelligent feature automatically recognizes scene content (e.g., human presence) and broadcasts configured audio alerts. It is widely applicable in urban management, public safety, traffic guidance, and maritime management. Future algorithm updates will support vehicle and forest fire recognition.
- Compact Size, Far-Reaching Sound: Weighing less than 130g, the MP120’s compact design ensures easy portability and minimal impact on flight performance, while its powerful sound pressure enables effective operations over 300 meters.
- Drone Landing Broadcast: Enhances user experience by enabling quick, automated broadcasting to remind ground personnel of an imminent drone landing, thereby ensuring operational safety around the landing zone.
Product Display & Compatibility
The MP120 Digital Voice Broadcasting System comes with inner packaging support, making it suitable for the DJI Mavic 3 enterprise AI broadcast safety case. This ensures convenient and secure storage during transport, keeping the device protected and ready for rapid deployment.

Intelligent Scene Broadcasting
The MP120’s AI Scene Broadcasting feature represents a significant advancement in automated drone operations. After selecting the target algorithm, the system automatically broadcasts pre-configured audio content when target objects are recognized within the camera’s view. This capability is already deployed in:
- Urban Management: Automated public announcements and alerts
- Public Safety: Real-time situation broadcasting and crowd guidance
- Traffic Guidance: Dynamic traffic flow communication
- Maritime Management: Port and waterway safety broadcasts
The system currently supports human recognition, with vehicle and forest fire detection algorithms in development. This ensures the MP120 evolves with your operational needs, providing long-term value and adaptability.
