Motor Nonlinearities in Electrodynamic Loudspeakers: Modelling and Measurement
This paper studies the motor nonlinearities of a classical electrodynamic loudspeaker. Measurements show the dependence of the voice-coil inductance with its position and with the driving current as well as the force factor dependence on the coil position. They allow the tuning of th...

| description | This paper studies the motor nonlinearities of a classical
electrodynamic loudspeaker. Measurements show the dependence of the voice-coil
inductance with its position and with the driving current as well as the force
factor dependence on the coil position. They allow the tuning of the parameters
of a model proposed for these dependences. Time and frequency analysis of the
model help in the explanation of both the harmonic and intermodulation
distortions observed in classical loudspeakers. |
