A virtual electronic piano which uses FPGA as the central control unit and uses ultrasonic ranging technology to form a virtual keyboard is introduced, and it has seven syllables generated by separating frequency of system clock. After being simulated in ModelSim and tested in physical commissioning, this electronic piano can work well. The electronic piano has a simple structure and is pretty entertaining, so it might has certain market value.
