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 1):
An audio reproduction device that amplifies an input signal which is an audio signal to obtain a supply signal, and outputs the supply signal to a speaker device connected to the audio reproduction device, the audio reproduction device comprising:\n 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.
