| 摘要 |
Drive assembly for acoustic sources having sound emitting surfaces (1) adapted to be excited into vibrational motions, especially for use in seismic surveys, comprising an electric rotational motor with at least one associated axle comprising at least an axle part (18) and a number of rods (21, 22) arranged radially in relation to the axle, having inner ends being influenced by the axle part (18) and outer ends being adapted to excite said sound emitting surfaces (1) into vibrational motion, in which the inner ends of the rods are connected to the axle part (18) and the connection is adapted to perform both push and pull forces upon the rods, and there is provided one or more spring elements (23) between at least one of the rods (21, 22) and the sound emitting surfaces (1).
