The 'click' you hear, when pushing button on ultrasonic controls is a tiny hammer dealy, that hits a metal bar, that is mounted in compliant attachments, and that will emit a decent amount of ultrasonic audio power. Metal bar resonates somewhere in the band the audio microphone receiver circuit accepts... (I might guess, 16 khz audio ?) |
