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 3):
The audio reproduction device according to  claim 1 , wherein\n the signal amplifier has a low-pass filter connected to the speaker device, and the characteristic measuring device is connected between the low-pass filter and the speaker device, and obtains the characteristic of the speaker device by measuring a frequency, amplitude, and a phase of an output of the low-pass filter when the measurement signal is supplied to the speaker device through the signal amplifier.
