What is the sound-generating principle of the electric wind instrument?

The electric wind instrument /electronic-wind-instrument/electric-saxophone-ewi.htmlis an electronic musical instrument, and its sound-generating principle is mainly based on electronic technology. It senses the player's breath, fingering and other operations through built-in sensors, and converts these physical information into electrical signals. Then, these electrical signals are processed by the circuit inside the instrument, calling the pre-stored timbre data, and finally output the sound through the speaker or external audio device. Its uniqueness lies in that it can simulate the timbre of many traditional wind instruments and other types of instruments, and can make various adjustments and modifications to the timbre, which is different from the principle of traditional wind instruments that rely solely on air vibration to generate sound.
