Piezo Spherical Dome Tweeter with Flare (L001) for ultrasonic Sound Generator M048N

in this video I want to show you how to make it amplified ultrasonic sound system for this Israel you will need a 12-volt power supply general electronic tools a soldering iron as well as flux and solder a tweeter speaker capable of ultrasonic frequencies an amplifier also capable of ultrasonic frequencies an ultrasonic frequency generator some signal wires to connect the frequency generator to the amplifier and some speaker wire to connect the speaker to the amplifier also possibly needed are some resistors for the first step I want to take the outputs of the power supply and plug them into the inputs of the amplifier make sure do not get the grounds and the positive 12-volt mix up so black is ground yellows typically the 12 volts so I'm going to get the ground and plug it into the ground right here GND is ground so all you do is loosen the screw insert these on each side of the screw
