Multiple acoustic transducer line array waveguide beam formation system and method thereof.

摘要

A compact mobile directional high sound output generating and intruder warding device is disclosed comprising a waveguide to accommodate plurality acoustic transducers arranged in a line array and facing a linear parabolic profile(4) in such a manner that it could project the acoustic beam as a unified whole and in directional and controlled manner and the waveguide (14) having identical sides with slopes away from the axis(1) and a fourth side section C (13) with an exponential profile to focus and combine the acoustic wave front. An acoustic plurality transducer to generate acoustic wavelengths of desired frequencies a digital signal processor to digitize process the signal in frequency domain. The said waveguide are further placed adjacent to each other in a flat plane of matrix and thereby forming constructive coherences in between the wave fronts emanating from the plurality transducers such that the acoustic waves are projected in a controlled and directional manner and with high sound pressure levels.
