An ultrasonic Phased Array made out of 8x 10mm ultrasonc transmitters.
How it works:
The ultrasonic emitors generate 40KHz sinus sound waves whose phase can be controlled with the TC78H621FNG wave generator.
By combining such type of waves, you can make interferences to increase or decrease the intensity of a wave.
If the waves have the same phase, the intensity of the wave doubles, and if the waves have oposite phases, they cancel out.
This examples can be seen in the following picture:
 | By combining multiple emitors, you can make a narrower sound wave like an sound LASER and also, by changing the phase of the waves, you can dirrect the waves at different points without any moving parts. |
This is the way that ecographyes and 5G work. Also, if you want to find more about this subjects like doppler effect, analog phased array and waves in general, you can read more at the following links:

Questions
How big is the PhasedUltrasonicArray PCB?
It measures 84.5 × 25.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PhasedUltrasonicArray use?
19 parts, built around the TC78H621FNG,EL. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PhasedUltrasonicArray KiCad files?
From the Tonikiller10000/UltrasonicPhasedArray repository on GitHub, at the commit this page was made from: the board is PhasedUltrasonicArray.kicad_pcb and its schematic PhasedUltrasonicArray.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PhasedUltrasonicArray design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tonikiller10000 before reusing the design.
