Demolition and rescue category - handheld sound wave disperser

Demolition and rescue category - handheld sound wave disperserBy using technologies such as directional sound, efficient electroacoustic conversion, dynamic coil transducer, and strong acoustic emission, the sound wave beam is controlled to propagate directionally within a range of (± 15 °). The remote shouting function can convey clear voice commands within a range of 1 kilometer. Realize functions such as dispersal, driving away, subduing, alerting, warning and warning, evacuation guidance, remote shouting, and guidance, and play an effective role in deterrence, warning, and proactive prevention.

Dismantling and rescue category - principle of handheld sound wave disperser product

Long distance directional sound wave system（RADD）It is a remote directional sound wave emitting device,Concentrate the sound in front of the device ±15Long distance directional propagation within a range of degrees. Its frequency has been optimized to400-6KHzWithin the audible range of the human ear, it can transmit highly directional and clear speech information, and has strong sound deterrence capability.
