Abstract:
An audio reproduction device includes: a signal amplifier that amplifies an input signal; a characteristic measuring device that obtains a characteristic of the speaker device based on a supply signal obtained by using, as the input signal, a measurement signal having a predetermined frequency characteristic; a structure analyzer that identifies a structure of the speaker device based on a result obtained by the characteristic measuring device; a delay characteristic calculator that calculates a delay characteristic of the speaker device according to the identified structure of the speaker device; a correction parameter generator that generates a correction parameter based on a difference between the delay characteristic calculated by the delay characteristic calculator and a target delay characteristic; and a corrector that corrects the input signal input to the signal amplifier based on the correction parameter generated by the correction parameter generator.

Claim (Index 2):
The audio reproduction device according to  claim 1 , wherein the characteristic measuring device is connected between the signal amplifier and the speaker device, and obtains the characteristic of the speaker device based on a signal which has a correlation to impedance of the speaker device, by measuring the signal which is an output of the signal amplifier when the measurement signal is supplied to the speaker device through the signal amplifier.
