first post here so feel free to point out my shortcomings.
I am interested in building an Ultrasonic device utilizing two Ultrasonic piezoelectric transducers to create a standing wave between them in order to 'float' droplets of water and other small objects. I am attempting to better understand the nature of focused compression waves in regards to electronic propulsion.
I've purchased these: LYWS High Conversion Efficiency... https://www.amazon.com/dp/B01LXMWLGE?ref=ppx_pop_mob_ap_share
I am attempting to use my laptop as an arbitrary waveform generator using the output of my audio jack. It is a Windows based machine, using MATLAB or similar software outlined in this post "https://www.allaboutcircuits.com/technical-articles/how-to-use-your-computer-as-an-arbitrary-waveform-generator/".
My question is this, what type of amplifier should I use to get the amplitude up to the 50W required to power the transducer? I am thinking of using an audio amp but am unsure if the line voltage will be off or if I'll even be able to reach the 50W. I'm looking to achieve minimal distortion without having to create a special amplifier that only works on specific signals, since I am trying to create something that is adjustable in order to experiment with different materials caught in the compression wave. I'm assuming that there is a range of voltage in the Ultrasonic frequency that this device can use but I'm unsure as this is my first attempt to create something with these devices. Should I just purchase an arbitrary waveform generator? Will that still need some sort of amp?
This whole project is a bit advanced for me and I'll admit that I dropped out of electrical engineering school, but we never really covered analog waveform generation anyway.
Any feedback is much appreciated 😁👍👨🔬
