The transfer function of the speaker model derived in Chapter 6 is, for c = 0,
X(s)/V(s) = Kf /(mLs3 +mRs2 + (kL + KfKb)s + kR)
Where x is the diaphragm's displacement and v is the applied voltage. A certain speaker has the following parameter values:
m = 0.002 kg
k = 106N/m
Kf = 20N/A
Kb = 15 V.s/m
R=10Ω
L = 10-3 H
Obtain the speaker's frequency response plots. Determine the speaker's bandwidth and resonant frequency, if any.
