APPARATUS FOR CONTROLLING SONIC ENERGY DISTRIBUTION

摘要

An electromechanical transducer is provided for producing pulses of sonic energy and respondingly generating electrical signals relative to received sonic energy wherein a driver generates the sonic pulses; and an improvement for projecting the sonic energy in a peculiar controlled pattern is a wave guide interposed at the output of the driver for controlling the propagation of the pulses by setting up substantially a line source of sonic energy which emanates the sonic energy in an operating pattern of at least a minimum intensity near the point of greatest breadth of the pattern.
