SOUND REPRODUCTION DEVICE

PROBLEM TO BE SOLVED: To provide a sound reproduction device for generating a nonlinear distortion correction signal that enables the adjustment of a nonlinear distortion included in sound to be reproduced by an electrodynamic speaker by including the reduction of a nonlinear distortion.SOLUTION: In a sound reproduction device, a voice coil state calculation unit of a signal processing circuit calculates the prediction displacement x, prediction velocity v, and prediction acceleration (a) of a voice coil in a virtual electrodynamic speaker with respect to an input sound signal concerning the virtual electrodynamic speaker that is set by a second nonlinear parameter different from the first nonlinear parameter of an electrodynamic speaker and a second linear parameter, and outputs them to a nonlinear distortion correction signal generation unit. The nonlinear distortion correction signal generation unit generates a nonlinear distortion correction signal on the basis of the prediction displacement x, the prediction velocity v, the prediction acceleration (a), the first linear parameter and first nonlinear parameter of the electrodynamic speaker, and the second linear parameter and second nonlinear parameter of the virtual electrodynamic speaker.
