Long-distance Directional Double Sound Wave Loud sound Drive Away System

Long-distance Directional Double Sound Wave Loud sound Drive Away System

Product Introduction:

The DY-QS4B2/33 Long distance directional sound wave strong sound drive away system is based on the strong directivity propagation mode of sound waves and emits powerful, loud and ultra-high decibel harsh noise within a certain coverage angle. 

It has high sound pressure level, strong directivity and clear sound. The effect distance is long, causing discomfort symptoms to the listeners and acting as a deterrent, thereby achieving the purpose of driving away. 

When working, it emits a beam angle (H×V): 10°×15° @2.5kHz/-3dB directional sound waves, which can broadcast clear voice information and high-intensity warning sounds (either real-time voice or pre-recorded voice) , the sound transmission distance is up to 4000 meters (STI-PA): ≥ 0.6, and the sound is highly directional: the sound in the forward area is clear and attenuated, and the sound in the rear and surrounding areas attenuates quickly and has little interference. This product also has a high-power amplifier function and can be used for emergency broadcasts, shouting, playing prefabricated sound sources, etc. It can also be used in large-scale publicity activities.

The high-precision and high-stable turntable adopts hybrid motor drive, has multiple protection functions, is designed to withstand strong winds, operates stably and reliably, has a novel shape, is easy to deploy, and is suitable for use in various harsh environments such as fixed or mobile outdoor situations.

Product Features:

Anti-salt spray, anti-corrosion, anti-mold, waterproof and earthquake-resistant.

◆ Rated power: 800W.

◆ Constant voltage input: 100V.

◆ Frequency response: 200-16000Hz.

◆ Maximum sound pressure level: 158dB±3dB.

◆ Beam width (H×V):10° ×15° @2.5kHz/-3dB.

◆ All-weather design, the shell is made of aerospace industry technology, resistant to acid and alkali, salt spray, and can withstand high-intensity impact and vibration. It has a windproof level of 12 and a protection level of IP66;

◆ The test conditions are: normal temperature (25°C), relative humidity of 20%, no wind, and free sound field. The maximum peak output sound pressure level at 1 meter can reach more than 158dB, the effective dispersion distance is 250 meters, and the voice transmission distance is 70db at 3000 meters.

◆ Sound is transmitted in a concentrated beam with sharp directivity. Within the effective dispersion range of the sound beam axis, it can cause auditory pain or even cause hearing loss in a short period of time.

◆ Aerospace composite materials, high strength, light weight and good protection;

◆ It has multiple functions such as shouting and playing sound sources, with clear and loud sound and long range;

◆ The wide dynamic range formed by the combination of the power amplifier operating power supply and the speaker protection circuit provides guarantee conditions for efficient electroacoustic conversion;

◆ The sound is highly directional: the sound in the forward area is clear and has low attenuation, and the sound in the backward and surrounding areas is rapidly attenuated with little interference;

◆ The design of high-efficiency electro-acoustic conversion system (standard sound pressure level + high-efficiency beam energy speaker) achieves the design goal of high sound pressure level/low driving power consumption.

◆ After linking with radar, it can realize automatic tracking to drive away strong sounds and automatic tracking and shouting deterrent functions.

Scope of Application:

It can be used for law enforcement on official ships, commanding heights in cities, border and coastal defense, waterways, airports to drive birds away, vehicle-mounted patrol environments, prisons, military exercises, anti-terrorism, etc. It can be used alone, or can be linked with radar or photoelectric turntables to carry out all-round and precise driving away from targets.
