This paper introduces a virtual electronic keyboard that uses FPGA as the core control component, uses ultrasonic ranging technology to form virtual keys in space, and uses frequency division to achieve 7 scales. After ModelSim simulation testing and physical debugging, the electronic keyboard can better realize the music playing function, has a simple structure, strong entertainment, and has certain market promotion value.
