Product Overview

The Portable High-Intensity Directional Acoustic Projector, Long-Range Wireless Hailing, Non-Lethal Acoustic Dispersal Device (also referred to as the Portable Acoustic Disperser or Acoustic Disperser) is a non-lethal police acoustic equipment integrating ultra-high sound pressure directional output, long-range voice command and audio playback functions, constituting a core tactical noise-communication and denial equipment in the fields of special police counter-terrorism EOD emergency response and criminal technical site control. This product is deeply customized for tasks such as counter-terrorism emergency response, mass incident management, major event security, and search-cordon in complex environments, enabling long-distance, non-contact personnel warning, psychological deterrence and safe dispersal. It perfectly adapts to rigorous operational scenarios such as clear commanding and hailing in noisy environments, psychological persuasion of high-risk targets, and crowd order management. By focusing acoustic energy within a narrow beam through a specialized acoustic structure, the system can generate an overwhelming sound pressure effect to force targets to retreat, while simultaneously projecting intelligible voice commands over a kilometer away, fundamentally resolving the pain points of traditional loudspeakers such as insufficient sound pressure, poor directivity and single functionality. It provides frontline commanders with lawfully compliant non-lethal force options and a highly efficient command platform, serving as a critical tactical technical equipment for enhancing on-site control capability in counter-terrorism and emergency response, ensuring law enforcement safety and public order.

Technical Principle

The system is architected strictly on the principles of electroacoustic transduction and acoustic beamforming. Its core consists of a signal input module, a power amplifier and a highly directional speaker array. When a commander sends a voice command via a wireless microphone or plays a preset audio file, the electrical audio signal is fed into the high-power amplifier for drive amplification, and then converted into high-intensity sound waves by specially designed transducer units. Through precisely calculated acoustic horn or phased-array structures, the system focuses this acoustic energy into an extremely narrow beam angle and radiates it directionally forward, avoiding energy dissipation into the surrounding space and thus achieving long-distance, high-fidelity sound projection.

During operation, the system can be switched between two modes based on mission requirements: a high-power continuous tone or modulated tone for strong psychological deterrence; and a voice mode for precise command delivery. Due to the directional propagation characteristics of sound waves, the sound pressure level behind and beside the operator is relatively low, effectively reducing collateral impact on friendly personnel and non-target area populations, satisfying the core requirements of precision strike and minimized collateral damage in non-lethal force use. The overall design complies with relevant technical standards for non-lethal weapons; under standardized operation, it produces temporary, reversible effects on the auditory and nervous systems, providing law enforcement officers with an important intermediate response measure before escalation of force. The technical principle fully aligns with the legal spirit of the principles of proportionality and minimum injury.

Core Functions and Compliance Operational Value

High-Intensity Directional Sound Pressure Output, Achieving Long-Range Precise Denial and Area Deterrence
The system can instantaneously generate a maximum sound pressure level of 132dB, concentrated and emitted through a narrow beam angle of approximately 20°. Its deterrence effective range reaches 150 meters, while the effective voice warning range extends to 1000 meters. This capability enables law enforcement officers to rapidly apply acoustic suppression to specific targets or areas from a relatively safe standoff distance, forcing offenders to cover their ears and retreat or lose their assault capability, while interference to unrelated nearby individuals is significantly reduced. Its precise directivity meets the regulatory requirements for target precision in non-lethal force use, avoiding collateral impact on individuals who do not pose a threat to public safety, thereby providing a legally valid tactical option for perimeter clearance in mass incident management and targeted deterrence at terrorist flashpoints.

Integrated Command and Audio Playback Dual-Mode Operation, Enhancing On-Site Law Enforcement Communication and Legal Notification Capability
The device features dual-mode functionality with a wireless microphone hailing function (reception range up to 100 meters) and playback of pre-recorded audio such as MP3. The commander can flexibly switch between real-time voice hailing and looped legal notice broadcasting based on the situation, realizing a graduated tactical communication sequence of warning—dispersal—command. This function deeply aligns with the normative requirements in law enforcement procedures for prior on-site warning, identity announcement and legal notification, preventing misunderstanding escalation due to communication breakdown, while also ensuring clear command and dispatch delivery in noisy environments (e.g., under a helicopter). It makes every acoustic operation a normatively sound law enforcement action with legal basis.

Portable Power Supply and All-Terrain Adaptability, Supporting Cross-Scenario Emergency Response Operations
The device is equipped with a built-in high-performance battery and supports DC12V vehicle-mounted or external power supply, ensuring uninterrupted power during field operations or prolonged cordon missions. Combined with a waterproof cover, shoulder strap and multi-purpose mounting brackets, it can be handheld, carried on the back, or rapidly fixed onto vehicles, barricades, elevated positions etc., achieving seamless switching between individual patrol carry and positional deployment. This highly autonomous mobile power supply capability meets the operational requirements for rapid deployment and sustained combat in counter-terrorism EOD and emergency response missions, providing reliable energy and physical support for establishing cross-regional emergency acoustic defense lines, complying with the stringent requirements of police equipment for mobility and environmental adaptability.

Safe and Controllable Non-Lethal Denial Characteristics, Strictly Limiting the Level of Force Application
As a physical dispersal type non-lethal weapon, the intense sound waves generated by this device primarily cause temporary hearing threshold shift, psychological panic and disorientation and other reversible effects on the target under standardized operation, with typical spontaneous recovery after cessation. Its design philosophy strictly follows the legal frameworks of “minimum force” and “proportionality” in international law enforcement, filling the gap between verbal warnings and direct physical force, and providing a graduated coercive measure for scenarios involving large-scale unlawful assembly or armed resistance that do not constitute a lethal threat. The equipment must be used strictly according to training norms, targeting areas slightly above the head with short bursts, avoiding prolonged close-range exposure, thereby achieving the tactical objective while minimizing the risk of irreversible injury and safeguarding the legitimacy and justification of law enforcement actions.

Compliant Application Scenarios

Counter-Terrorism Emergency Response and Mass Incident Scene Control Scenario
In sudden incidents seriously endangering public safety such as terrorist attacks, large-scale unlawful assemblies, and violent riots, response forces deploy this acoustic disperser at the forward edge of the defense line. Following statutory procedures, they first play pre-recorded legal warnings over a long distance, then apply targeted high-intensity acoustic suppression against ringleaders or violent resistors, dismantling their psychological defenses and group cohesion, thus creating favorable conditions for tactical actions such as segmentation, dispersal and targeted arrest. The entire application strictly adheres to the Emergency Response Law and regulations on the use of police equipment, ensuring that acoustic dispersal as a pre-escalation warning measure effectively controls the situation while preventing its expansion.

Major Event Security and Long-Distance Warning Around Key Targets Scenario
During large-scale sporting events, celebrations, important conferences, etc., at perimeter fences or cordon lines, this equipment is mounted on sentry posts or patrol vehicles to form a voice warning barrier extending up to a kilometer. Upon detecting individuals attempting to climb over, breach, or engage in other disruptive behaviors, security personnel can issue clear warning commands to drive them off without needing to approach; if ineffective, a short burst of intense sound is applied, greatly extending the security defense depth. This deployment model provides a non-contact initial defense layer for VIP protection and critical infrastructure protection, meeting the requirements of various large-scale mass activity safety management regulations regarding security force deployment and emergency response measures.

Investigation-Search Cordon and Psychological Warfare Against High-Risk Targets Scenario
During cordon-search operations against armed suspects, explosive-laden criminals, or individuals holed up in enclosed spaces, negotiators or assault team members can use the device's ultra-long-range hailing function to conduct psychological persuasion from a safe position behind cover, continuously broadcasting family members' surrender appeals or legal policy statements to undermine the suspect's will to resist. When necessary, short-burst intense sounds are used to disrupt the suspect's hearing and judgment, covering the approach of the assault team. This tactical application plays a critical role in actions such as counter-hostage and counter-riot operations by protecting hostages and reducing friendly casualties, with operating procedures strictly adhering to the Criminal Procedure Law and on-site law enforcement guidelines for police officers regarding measures to stop crimes and apprehend suspects.

Emergency Command and Public Information Broadcast Release Scenario
At emergency rescue sites such as earthquakes, floods or major traffic accidents, this device serves as a highly mobile emergency broadcast station, allowing rescue commanders to convey critical instructions such as evacuation routes, shelter locations and supply distribution to stranded or obstructed crowds, maintaining effective information delivery amidst the noise of rescue operations. Its portability enables it to rapidly reach core areas cut off from traffic, becoming a reliable voice communication terminal in the on-site emergency command and dispatch system, effectively supporting the work requirements stipulated in emergency management laws and regulations regarding timely warning release and organized personnel evacuation and relocation.

Core Technical Parameters

In terms of acoustic performance, the operating frequency range of this acoustic disperser covers 200Hz to 5kHz, balancing voice intelligibility and acoustic deterrence energy. The maximum sound pressure level reaches 132dB, emitted as a precisely directional output with a beam width of approximately 20°, effectively ensuring deterrence efficacy. Voice transmission is clearly intelligible up to a range of 1000 meters, meeting the requirements for long-range warning and command dispatch, while the deterrence and dispersal effective range against specific targets reaches 150 meters, enabling denial effects from a relatively safe standoff distance.

With respect to functional configuration, the device supports wireless microphone real-time hailing with a reception range of approximately 100 meters, allowing the commander to operate flexibly away from the emitting unit. It has a built-in MP3 and other audio file playback function, capable of pre-recorded warning messages, legal provisions etc. for loop or triggered playback. It is also compatible with various external audio signal inputs, extending the integration application space with communication or interception systems. The integrated design consolidates three major modules: hailing, playback, and convenient audio access.

For electrical and physical characteristics, the rated power is 150W, using a DC 12V power supply system. It is equipped with a built-in high-performance battery and comes with a DC12V/20A vehicle charger or AC adapter, ensuring dual-guaranteed power in field self-sustained and vehicle-powered modes. The external dimensions are approximately 200mm × 290mm × 330mm, with a compact structure. Standard accessories include a mounting bracket, waterproof cover, handheld wireless microphone, carrying strap and power adapter, enabling rapid deployment on multiple platforms.

Compliant Field Application Cases

During a major international sports event held in a coastal city, clashes among fans outside the venues escalated into a mass pushing and shoving incident. The on-site security command center swiftly mobilized a mobile response squad equipped with this acoustic disperser to the flank of the core incident area. After verbal warnings proved ineffective, the squad members activated pre-recorded multilingual legal warning messages on loop from a safe distance, clearly conveying the command to "immediately cease unlawful acts and disperse in an orderly manner." Simultaneously, they intermittently emitted short bursts of intense sound at approximately a 20° angle targeting the leading troublemakers, forcing them to cover their ears, stop shoving, and retreat. The entire response restored peripheral order within minutes without causing any casualties or permanent hearing damage, effectively achieving the tactical goal of dispersing the crowd lawfully during a major event and safeguarding the national image and public safety. The operational audio logs and disposition recordings served as compliant evidence in the subsequent incident investigation.

During a cordon-search for an armed suspect hiding in a rural standalone residential house, a provincial public security authority tasked negotiators to use the device's ultra-long-range hailing function from a safe position approximately 500 meters away, continuously engaging the suspect in psychological persuasion and broadcasting family members' recorded surrender appeals. When the suspect showed signs of suicidal tendencies and attempted to ignite gas, the commander decisively ordered a single burst of directional intense sound, momentarily disrupting the suspect's behavioral continuity and providing an opportunity for the assault team to breach and effect a rescue. The suspect was ultimately safely subdued. In this operation, the critical role of the acoustic disperser in psychological warfare and tactical coordination was validated. The entire process strictly adhered to the force use regulations, causing no organic injury to the suspect, and strongly supported the legitimacy review of the law enforcement procedures.
