Abstract
An ultrasonic transmitter. The ultrasonic transmitter includes a first enclosure, a second enclosure, a piezoelectric transducer, a first piston, and a second piston. The first enclosure has an opening for directing an output of the ultrasonic transmitter in a first direction and a wall opposite the opening. The second enclosure has a first opening aligned in the first direction and a second opening opposite the first opening. The second enclosure is positioned in the first enclosure with the second opening directed toward the wall. The piezoelectric transducer is positioned in the second enclosure and movable relative to the first enclosure. When an ultrasonic electric signal is applied to the piezoelectric transducer, the piezoelectric transducer expands and contracts pulsing the first and second pistons to produce ultrasonic sound waves from the first and second openings which combine and our output by the ultrasonic transmitter.
