Dewelopment of powerful self-reactance emitter of sound is for creation of the local acoustic field of high intensity

Powerful self-reactance emitter of sound of mobile type which creates the voice field of high intensity on the set distance and in the narrow sector of corners that technology of forming of the acoustic field by the use of багатоелементних фазованих arrays. The effective ultrasonic transformers of flexural and electrostatic types which can be a base for creation of багатоелементної powerful HEADLIGHTS are developed. Acoustic pressure is got from the 1th emitter (125 – 135) of дБ in the distance a 1 mcode, what fully sufficiently for creation of багатоелементної HEADLIGHTS.
