Resin Reed Tip Slope Controls Harmonics

The patent applies parameter changes by modifying the geometric parameters of the reed tip and tip rail. Specifically, the tip is designed with a sloping shape where the upper surface is inclined relative to the lower surface, creating an asymmetric geometry that alters the vibration characteristics. The tip rail is also designed with a specific sloping shape to work in conjunction with the tip. These geometric parameter changes modify the opening cross-sectional area during vibration, thereby suppressing excessive high-order harmonics while maintaining the benefits of resin material manufacturing.

The patent applies local quality by creating non-uniform geometry specifically at the tip and tip rail regions. The tip features a sloping shape with different upper and lower surfaces, and the tip rail has a corresponding sloping design. These localized geometric modifications are concentrated at the critical vibration interface between the reed and mouthpiece, while the rest of the reed structure remains relatively simple. This approach reduces high-order harmonics through localized geometric complexity rather than overall structural complexity.
