sound radiator 中文意思是什麼
sound radiator
解釋
聲波輻射器-
Radiation modes are dependent on the radiator ' s geometry shape and vibration frequency, but are not relative to the material characteristic and the border condition of the radiator. further more, the radiation efficiency of the radiation modes falls off very rapidly with the increase of modes order at low frequency. the adjoint coefficient of sound radiation modes is proportional to the corresponding sound radiation power
聲輻射模態由輻射體的幾何形狀和振動頻率決定,與輻射體本身的材料特性以及邊界條件無關;特別是在中低頻率時,聲輻射模態對應的輻射效率隨模態階數的增加而迅速降低。
