For the Pioneer A11EC80-02F 4.5" Fullrange loudspeaker driver discussed in class:
Compute the moving mass, mechanical damping coefficient, and spring stiffness
of the loudspeaker driver.
Given an input harmonic voltage of amplitude 1 V, plot the velocity amplitude
in mm/s versus frequency over a frequency ranging from zero to twice the free air
natural frequency. Assume that the driver operates in a vacuum.
Over the same frequency range, plot the power in milli-Watts dissipated in the
coil resistance.
