Ultrasonic Converters - Artech Ultrasonic Systems Converters The generator converts electrical energy into high-frequency energy, which is then transduced by the converter into ultrasonic vibration. The sound waves cause the screening mesh to vibrate in a high frequency range.
matlab - Converting audible sound to ultrasonic - Stack ...
https://stackoverflow.com/questions/48436756/converting-audible-sound-to-ultrasonic
I want to convert them into ultrasonic range so that when I transmit them they are not audible to humans. I read that I need to use amplitude modulation. I used the modulate function of matlab. [y,Fs] = audioread ('TakeASelfie.mp3'); x = modulate (y,30700, 62000, 'amdsb-tc'); soundsc (x,62000) audiowrite ('modulated.wav', x, 62000) In the above ...

The Ultrasonic Principle of Operation A piezoelectric transducer immersed in a water bed, converts a high frequency, electronic signal into a high-frequency mechanical oscillation. As the oscillation speed is increased to a level where the water particles can no longer follow the oscillating surface, a momentary vacuum and strong compression ...
