Abstract

Приводной узел для используемых в сейсмических исследованиях акустических источников с вибрационными поверхностями (1), которые могут быть приведены в вибрационное движение, содержит раму (4), включающую по меньшей мере одну приводную часть (3, 13), предпочтительно расположенную по центру. Приводной узел содержит также два или более устройства (2) крепления, установленных относительно звукоизлучающих поверхностей (1) и расположенных с противоположных сторон рамы, два или более гибких передающих элемента (5), соединяющих устройства (2) крепления друг с другом и проходящих с обеих сторон от оси, проходящей между двумя устройствами крепления, две или более вторых приводных частей (6, 7, 16, 17), соединенных с передающими элементами (5) и расположенных с возможностью взаимодействия с первыми приводными частями (3, 13) с образованием электромагнитных приводов, причем каждый из электромагнитных приводов обеспечивает управляемое относительное колебательное движение соответствующих приводных частей (3, 6, 7, 16, 17).Международная заявка была опубликована вместе с отчетом о международном поиске.
