因口型问题而影响唢呐簧片的合理振动,引发音准、音色、音量以及斜音等问题的产生,这是唢呐学生的吹奏中普遍存在的问题,但是并没有引起他们的足够重视,笔者以物理学、医学等理论为依据分析了问题产生的原因,论证了“下颌骨前伸”是解决问题的关键。 Due to the mouth-type problems affect the reasonable vibration of the reed leaves, resulting in pitch, timbre, volume and beep sound and other issues, which is undaunted by students playing in the ubiquitous problem, but did not cause them enough attention, the author to Physics, medicine and other theories as the basis for analysis of the causes of the problem argues that the “mandibular advance” is the key to solve the problem.
