Conical Air Column

圆锥形空气柱

A conical air column will produce the same fundamental frequency as an open cylinder of the same length and will also produce all harmonics.

一个圆锥形空气柱将产生与相同长度的开放圆柱相同的基频,并会产生所有谐波。

Conical air columns are employed in several of the woodwind musical instruments: oboe, bassoon, saxophone, and others.

圆锥形空气柱被用于多种木管乐器中:双簧管、大管、萨克斯管等。
