CASI-Triple 18 Sound Emitter & Bird Scarer

Chinese Academy Sound Image (Tianjin) Science & Technology Co., Ltd

Intriduction:

CASI-Triple 18 is a strong sound source used for low frequency musical entertaiment, infrasound emitter for testing and bird scarer in airport or farm. It could generate broad band sound even very low frequency to scar bird or other small kun insects. Based on a stable structure, intensity of the sound can be adjusted remotely over 500m in any way to change its propagation range without impulse noise. The source body would not be deternorated when operating in enviroment with oil, water, salt in long time from -50℃to +75℃ and 99% humidity.

Its vibration unit works in strong magnetic field of 1.8T with a 18 inch cone basin made by carbon fiber. Sound wave is emitted by a large surface of the cone efficiently. Two assistant cones work coordinating following the main cone driven by strong current in coil with power of 1000W，to generate sound wave among 1Hz to 20000Hz with f0 of 15Hz and flat curve among 20Hz to 5kHz.

Application：

Low frequency musical entertaiment, Boat, airport and farm bird scarer, Sound source for testing, Low frequency music play in an alfresco concert.
