Analytical solutions for axisymmetric vibration of loudspeaker cones in transitional range

The loudspeaker cone vibration in the transitional frequency range in which the governing equations have transition or turning points is studied by applying the uniformly valid solutions obtained in a previous paper. The solutions are presented analytically as well as the resonant and anti-resonant frequency equations, the associated patterns and the axial admittance. A new frequency equation for the non-bending effect is obtained. The results agree well with numerical results.
