The system of multifunctional electronic wind instrument

The invention discloses a system of multifunctional electronic wind instrument, including a blowing apparatus and a data processing apparatus. The blowing apparatus includes a casing, an air blowing tube, a pressure sensor, a controller, a plurality of pressing switches and a wireless signal transmission module. The pressure sensor includes an air pipe. When a user blows against an air inlet of the air blowing pipe to flow a main gas through the blowing pipe and selectively presses the plurality of pressing switches, the pressure sensor senses a pressure signal associated with the main gas through the intake pipe, the controller transmits the pressure signal and a switching signal transmitted by the pressing switches through the wireless signal transmission module. The data processing apparatus receives the pressure signal and the switching signal, generates music information in accordance with selected tone information from a plurality of predetermined tone information, the pressure signal and the switching
