Claims (9)
1. An electronic whistle based on MIDI technology comprises a shell, a mouthpiece, an electronic screen, operation control keys (or a knob, a rocker and a multi-gear switch which can be combined in a plurality of ways), tone control keys (or a knob, a rocker and a multi-gear switch which can be combined in a plurality of ways), a USB interface, a USB cable, an internal control circuit board, a MIDI synthetic board, a sound output module, a wireless module, a pressure sensor (or a sound pick-up, a combination of the pressure sensor and the sound pick-up and the like), a gas channel adjusting screw, a battery and the like. The electronic whistle is characterized in that the electronic whistle detects air pressure (or sound frequency, amplitude, or air pressure, sound frequency, amplitude and the like) in the air channel through an air pressure sensor (or a sound pickup, a combination of the air pressure sensor and the sound pickup and the like) and transmits the air pressure to an internal control circuit board, the internal control circuit board judges the suction and blowing actions, the stress degree and the tone of a blowing hole to generate corresponding MIDI instructions, the MIDI instructions are synthesized and processed by a MIDI synthesis board and are sounded by a sound output module, or the instructions are transmitted to an external MIDI synthesizer, a device, a mobile phone or a computer through a USB cable or a wireless module and are processed and sounded by the outside.
