Product overview
YANGDA Sky Speaker-I brings recorded messages and live voice broadcasting to multirotor and fixed-wing platforms for rescue, search, firefighting and law enforcement negotiation. Its 500-gram speaker uses an internal magnetic design that does not interfere with the drone’s geomagnetic sensors or flight systems. Digital voice encoding reduces signal interference during airborne audio transmission. The speaker operates at 9-28V, with sound strength of 125db at 1m and 80db at 100m, and sound coverage of up to 1 km.
Operators can switch between SD card audio playback and real-time broadcasting through the handheld intercom. Custom MP3 and WAV files have no time or size limitations. A single intercom can control up to four speakers playing different content or coordinate synchronized broadcasting across multiple speakers; multiple intercoms can also operate one speaker. The handheld wireless intercom has four channels, nine recorded sounds, a 2200mAH battery and USB charging, with a maximum transmission range of 10KM.
