What are the main differences in the sound-producing principles of electric wind instruments and traditional wind instruments (such as saxophone, flute, etc.)?

There are the following main differences in the sound-generating principle between electric wind instruments /electronic-wind-instrument/electric-saxophone-ewi.htmland traditional wind instruments (such as saxophone and flute):
1. **Saxophone**:
- **Basic sound-generating components**: The sound of the saxophone mainly depends on the reed in the mouthpiece. When the player blows air into the mouthpiece, the airflow causes the reed to vibrate, thus producing the initial sound. The reed is a key source of vibration, and its material, shape, and installation tightness will affect the timbre and pitch of the saxophone.
- **Function of resonance chamber**: The saxophone body is a resonance chamber. The sound generated by the vibration of the reed propagates in the air column in the tube body, causing the air column to vibrate. Factors such as the shape, length, and size of the bell of the tube body determine the effect of resonance, which in turn affects the volume, timbre, and pitch of the sound. By changing the effective length of the tube body (the distance from the mouthpiece to the nearest open hole) through the key system, the player can control the vibration frequency of the air column to produce different pitches.
2. **Flute**:
- **Basic components for sound production**: The flute is produced by blowing air into the flute tube through the blowing hole, which makes the air column in the tube vibrate and produce sound. That is to say, after the player blows air into the flute, the airflow forms an air column in the flute tube, which is the basis for the flute to produce sound. The membrane of the flute is usually attached to the membrane hole, and the membrane will also vibrate under the action of the airflow, and it plays an important role in the timbre of the flute.
- **Function of resonance chamber**: The body of the flute is also a resonance chamber, and the sound produced by the vibration of the air column in the tube is amplified and modified in the resonance chamber. The structure of the flute is relatively simple, but the inner diameter and length of the body, as well as the position and size of each sound hole, have an important influence on the production of sound and the resonance effect.
3. **Electric wind instrument**:
- **Basic components for sound production**: The electric wind instrument is an electronic instrument. Its sound production principle is to trigger the internal electronic components, such as sensors, by vibrating the reed with airflow. When the player blows air into the mouthpiece of the electric wind instrument, the airflow causes the reed to vibrate, and the sensor converts the vibration of the reed into an electrical signal.
- **Electronic processing**: These electrical signals are converted into different sound signals through circuit processing and audio synthesis technology inside the electric wind instrument. Electric wind instruments can simulate the timbre of a variety of instruments, which is achieved through pre-set timbre models and parameters. Players can select different timbres, pitches, volumes and other parameters by adjusting various control buttons, knobs or touch screens on the electric wind instrument, thereby producing various musical effects.
