MM-S01 Wireless Megaphone System for Drone
China Moneypro
The MM-S01 Wireless Megaphone System for Drone is an advanced aerial broadcasting solution combining wireless audio technology with remote real-time communication capabilities. The drone-mounted speaker terminal weighs approximately 530g and delivers impressive 125dB maximum volume with broadcast range exceeding 150m. It features an internal magnetic horn to prevent UAV interference, built-in howling suppression for clean audio beyond 10m, and supports 12V-24V wide voltage input with customizable mounting interfaces for various drone models. The lightweight handheld controller at 253g offers one-key operation, 5km transmission range in open areas, exceptional durability with 1.5m drop resistance, and crystal-clear sound with less than 5% distortion. Both units feature CTCSS/CDCSS modes and tail cancellation. The system connects to mobile phones, tablets, and MP3 players via AUX cable for audio relay, making it ideal for dispersal, warnings, public broadcasting, and on-site command applications across multiple industries.

speaker terminal
The total weight is approximately 530g, with support for flexible payload configurations.
It delivers a maximum volume of 125dB, producing powerful sound that travels over long distances.
The internal magnetic horn effectively prevents interference with the drone’s geomagnetic system.
Equipped with a built-in anti-howling chip, no significant feedback noise is heard beyond 10 meters.
Wide voltage input from 12V to 24V, with multiple power protection features.
The speaker volume is continuously adjustable, and the broadcast range exceeds 150 meters.
Customizable mounting interfaces are available to suit various drone models.
Handheld side
Weighing just 253g, it’s lightweight and easy to handle. Features one-key shouting for quick communication.
Built with durable, high-strength materials for superior protection—withstands drops from up to 1.5 meters.
Long standby time plus low battery alert.
Transmission range up to 5km in open areas, with strong interference resistance.
Crisp, clear audio with less than 5% distortion.
Includes CTCSS/CDCSS modes and a tail-tone cancellation function.
Audio transmission via mobile phone
The Radio Broadcast Propaganda Device enables audio transmission functionality. The handheld unit connects to external devices such as mobile phones, tablets, and MP3 players via a 3.5mm double male AUX audio cable (as illustrated below).
Because the handheld side has a limited duration for audio transfer, the relay of sound signals is not continuous. Therefore, the PTT button must be pressed intermittently during operation.
