Sound from ultrasound is the name given here to the generation of audible sound from modulated ultrasound without using an active receiver. We(my and my teammates at that project) bought Ardunio Uno cards and HC-SR04 modules and made some "operation" on modules. Fixing the Reverb Tank. Though not much for documentation & details – this instructable shows off a transducer packed parametric speaker design. Product details. SoundLink Revolve+ is larger and generates higher-volume, more room-filling sound than SoundLink Revolve. Ultrasonic sound can be produced by transducers which operate either by the piezoelectric effect or the magnetostrictive effect.
