在乐器中应用棒的振动来发声的类别很多,从音叉、三角铁、木琴、铝板琴、梆子木、京胡板到各种簧片乐器都是。在声学里,棒振动的定义不仅决定干振动体的形状,还决定于振动体运动时是否以劲度为它向平衡位置恢复的主要力量。对于振动棒,劲度比张力重要,否则就成了弦振动。同样是一根细长的物体,当它的振动频率很低,波长比该物体直径大很多时,其振动性质可能接近强劲的弦,而在波长比直径小很多时,振动性质又接近于柔软的棒。在棒振动体中,以不同频率振动的波的传播速度和形状是不相同的,波速对棒而言并无普遍意义,这是和弦 The application of stick vibration in the instrument to sound a wide range of categories, from the tuning fork, triangle iron, xylophone, aluminum piano, shuttlecock, Keihu board to a variety of reed instruments are. In acoustics, the definition of rod vibration not only determines the shape of the dry vibrating body, but also determines whether the vibrating body is the main force at which it restores its equilibrium position with stiffness. For vibrating rods, stiffness is more important than tension, otherwise it becomes a string vibration. It is also a slender object whose vibrational properties may be close to a strong chord when its frequency of vibration is very low and the wavelength is much larger than the diameter of the object, whereas the vibrational properties are close to soft when the wavelength is much smaller than the diameter The stick In rod vibrators, the velocity and shape of the waves vibrating at different frequencies are not the same, and the wave velocity has no universal meaning to the rod, which is the chord
