Abstract
An improved ultrasonic lens and associated system is provided. Specifically, there is provided an ultrasonic lens with two sets of parallel sound ports operatively connected to an electrodynamic transducer to extend the working range of both audible and ultrasonic sound signals. The ultrasonic lens and electrodynamic transducer are situated so that the electrodynamic transducer axis and the sound port axes are aligned, whereby a shift in either the x or y axis direction will influence the ultrasound and audible behavior of the sound signal from the electrodynamic transducer.
