Abstract

The invention discloses a directional sound wave disperser which comprises a controller and a sounder. The controller comprises a power amplifier module, and the power amplifier module is a single-stage power amplifier and is used for carrying out power amplification on an audio signal. The controller further comprises a signal processing module which is connected with the input end of the power amplifier module and used for processing audio signals. The sounder comprises a high pitch head and a multi-fold horn, and the high pitch head is connected with the output end of the power amplifier module. A single-stage power amplification module is adopted to perform power amplification on the audio signal, so that the crossover distortion can be effectively eliminated, and the output efficiencyis improved. The multi-fold horn is adopted to output sound signals, so that sound waves are radiated more efficiently, and nonlinear distortion of the sound signals is reduced.

Description

technical field [0001] The invention relates to the field of sound wave technology, in particular to a directional sound wave disperser. Background technique [0002] The strong sound disperser uses high sound pressure level transduction to realize the long-distance directional transmission of high-intensity sound waves, and stimulates the human auditory organs and central nervous system through high-intensity noise, causing them to disable or escape, so as to achieve the purpose of refusing to disperse large groups of people. At the same time, the purpose of not causing permanent harm can also be used for long-distance broadcasting, publicity, warning, etc. to the crowd. The strong sound disperser has the characteristics of long transmission distance and low distortion. The user can play the internal prefabricated audio source or the external audio source file through the switch button, and make live announcements through the megaphone. [0003] Current acoustic diffusers...
