Device and method for emitting high-strength acoustic signals, and application thereof in remote directional propagation

Abstract

The invention discloses a device and a method for emitting high-strength acoustic signals, and an application thereof in remote directional propagation, in order to solve the problems in current non-lethal weapons such as large likelihood to cause harm and sequela to human body, difficult control of the effective range during the use and bringing about environmental pollution. The device comprises an audio signal output unit for outputting pre-recorded or instantly picked up audio signals; a power amplification unit for amplifying the audio signals input by the audio signal output unit so as to obtain high-sound pressure level acoustic signals with the amplitude between 110 and 150 decibels; and a transducer array for converging and emitting the high-sound pressure level acoustic signals. The device is used for emitting and propagating remote high-strength acoustic signals with the effective use distance between 500 and 1000 meters. Obtaining the remotely-propagated high-strength acoustic signals by means of the amplification of the audio signals, the device has the characteristics of causing no harm and sequela to human body, accurate control of the effective range during the use and bringing about no environmental pollution.

Description

technical field [0001] The invention relates to a high-intensity acoustic signal emitting device and method and its application in long-distance directional propagation, belonging to the field of high-intensity acoustic signal generation and application. Background technique [0002] In today's world, not only are regional riots and conflicts (such as looting, looting, and burning) and the threat of terrorist activities increasingly intensified, but also group riots caused by various reasons occur from time to time, endangering social stability. In order to maintain national security, various emergencies must be dealt with in a timely and efficient manner. Since group riots are very different from terrorist attacks, beating, smashing, looting and burning riots in terms of nature, harm, and participants, the principles, methods, and routine use of police weapons and equipment should also have essential differences. different. For all kinds of crowds and rioters, to quell ri...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a high-intensity acoustic signal emitting device and method and its application in long-distance directional transmission to solve the problem of relatively high possibility of causing harm to the human body and sequelae in existing non-lethal weapons. It is difficult to control the effective range of use and cause environmental pollution
