The YM-3S is a remote broadcasting system tailored for drone industry applications. It emits loud and clear sound, enabling effective communication across diverse scenarios. By leveraging the drone communication link, it allows for instant broadcasting and voice communication via the drone remote controller, eliminating the need for additional devices. Operations such as remote broadcasting, audio adjustment, and content dispatching can be seamlessly executed through the remote controller, making it highly adaptable to various application scenarios. It is compatible with DJI M300/M350 drones.
The product dimensions are 173.5mm×143mm×90mm (with a tolerance of ±1mm), and it weighs only 449g. Featuring a quick-release installation method, it can be easily integrated with the SkyPort V2.0 interface of DJI M300/M350 drones. This design ensures no extra burden on the drone's load, maintaining flight stability.
- Power and Sound Pressure: With a peak power of 50W and a maximum sound pressure of 130dBa, it can cut through noisy environments to ensure clear audibility.
- Broadcasting Distance: It has an effective broadcasting distance of 500 meters and an extended maximum broadcasting distance of 800 meters. Combined with an adjustable pitch angle ranging from 0° to 90°, it can precisely direct sound to target areas (such as crowds, disaster zones, and work sites).
It supports real-time broadcasting (instant voice transmission via the drone remote controller), recording/audio file playback (loop playback of pre-stored content in Mp3/Wav/Flac/AAC/Wma formats), TTS text-to-speech (instant conversion of text to voice for broadcasting), and alarm triggering. These modes cater to different scenarios like emergency command, order maintenance, and information dissemination.
Relying on the DJI drone communication link, the control distance matches the drone's video transmission distance. No additional devices are required; operations such as remote broadcasting, scheduling of broadcast content, and volume adjustment can all be completed via the drone remote controller. This simplifies processes and enhances response speed.
It operates within a temperature range of -20℃ to 65℃, capable of handling extreme outdoor scenarios such as forest fires in high temperatures and rescue missions in cold winters, ensuring continuous and stable sound output.
At disaster sites (such as fires and floods), real-time broadcasting can guide trapped people to safety and relay evacuation routes. TTS text-to-speech can be used to loop safety instructions, covering an 800-meter range to support efficient ground rescue efforts.
In crowded areas like large events and transportation hubs, pre-recorded audio files (such as order guidance and safety reminders) can be remotely played, or alarms can be triggered to evacuate crowds. The 500-meter effective distance ensures precise coverage and reduces personnel contact risks.
In construction sites, power inspection, and other scenarios, it can deliver operation instructions and safety warnings. The adjustable pitch angle allows targeted sound transmission to ground teams, improving coordination efficiency and reducing operational risks.
The YM-3S focuses on "lightweight integration, long-range clear sound transmission, and multi-mode adaptation". It deeply integrates with the DJI drone ecosystem to solve communication challenges in aerial operation scenarios. Serving as an efficient "voice extension" for drones, it enables precise and rapid aerial voice interaction in emergency response, public management, industrial operations, and other fields.
