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.

Abstract: An electrodynamic transducer having a coil, a membrane, and a plate is disclosed, wherein the transducer is adapted to generate a sound pressure level in the human-audible acoustic range and the ultrasonic range so that the transducer may be used as a speaker and an ultrasonic proximity sensor. The transducer may be adapted to generate a sound pressure level above about 88 dB between 20 kHz and 70 kHz. The plate may include a structural rigidity increasing feature such as a domed portion or a population of ribs, which may increase the generated sound pressure level in the ultrasonic range. The transducer may also include a front resonator which may be used to further tune and/or increase the generated sound pressure level in the ultrasonic range.
