摘　　要：本文在求解扬声器锥形振膜低频振动的基础上，得到了计算扬声器锥壳环反谐振频率的精确公式，并借助特征频率反比于质量平方根的物理概念，推出了适于工程应用的近似公式，其偏差在３％以内。An exact formula for the calculation of the ring antiresonance frequency of a loudspeaker cone is obtained, on the basis of solving the vibration of the loudspeaker cone in low frequency range. An approximate formula for engineering uses is also deduced with the help of physical conception that the characteristic frequency is in inverse proportion to the square root of mass,with an error of less than 3%.
