Product overview
The Yifei Zhineng YM-3S is an EF airborne broadcast loudspeaker payload for multirotor UAVs. Its compact assembly measures 170mm × 140mm × 90mm (±1mm) and weighs 480g ±10g, with quick-release mounting for aircraft integration. It uses a 24V supply and Ethernet communication. Compatible SIYI and Skydroid controller Ethernet links support full operation through the UAV controller app or Smart Payload app without additional supporting equipment. Payload parameters may be customized for the aircraft model, with the delivery contract governing the configuration.
The YM-3S supports live announcements, uploaded audio playback, text-to-speech, looping, one-touch alarms and male/female voice selection. It accepts Mp3, Wav, Flac and AAC files, offers multilevel volume adjustment and provides app-controlled pitch adjustment through 0–90° in real time. Rated and maximum power are each specified as 50W, with maximum sound pressure of 132dBa, effective broadcasting to 500 m and maximum broadcasting to 800 m. Its operating temperature range is -20°C to 45°C. These payload parameters may be customized for the aircraft model and are governed by the delivery contract.
