A long voice coil and a short one of loudspeaker with same turns are simulated under the circumstance of small signal in this paper.The characters of the force factor with varied displacement are emphasized,and the changing ratio of the long voice s force factor is lower than that of the short one s,the influence of frequency and displacement to the inductance of voice coil are studied at the same time,the changing ratio of the long voice coil s inductance is smaller than that of the short one s while the inductance of the two decrease with increasing frequency.The long voice coil has better fidelity than the short one while the short one with greater force factor and inductance is more adaptive for the high frequency with small displacement.
