Изобретение относится к области технической акустики, в частности к конструкциям сейсмической аппаратуры. Акустическая антенна, в которой, с целью уменьшения массогабаритных характеристик при неизменной рабочей частоте и ширине характеристики направленности путем излучения и приема поперечных акустических волн, резонирующее основание и акустический экран выполнены в виде прямоугольных стальных накладок с упорными выступами на одной их стороне, толщина накладки акустического экрана равна половине длины возбуждаемой в ней волны, а пьезоэлектрические элементы зажаты между перпендикулярными к верхней и нижней сторонам накладок плоскими поверхностями их упорных выступов. 4 ил.The invention relates to the field of technical acoustics, in particular to the structures of seismic equipment. Acoustic antenna, in which, in order to reduce the weight and size characteristics at a constant operating frequency and width of the directivity characteristic by emitting and receiving transverse acoustic waves, the resonating base and acoustic screen are made in the form of rectangular steel plates with thrust projections on one side of them, the thickness of the acoustic screen overlay is equal to half the length of the wave excited in it, and the piezoelectric elements are clamped between flat n perpendicular to the upper and lower sides of the overlays surface of a lip. 4 il.
