Abstract:
Provided are method and apparatus for evaluating audio device for evaluating performance of an audio device by inputting into the audio device an audio signal having a waveform in which a plurality of waves with different frequency components are superimposed, comparing the sound waveform before the input and the sound waveform after the input, and finding the degree of conformity therebetween. An audio device of the present invention is characterized in that, with sound field correction as a precondition, low-pitch ranges can be reproduced by using numerous small-diameter speakers, a single one of which is insufficient to reproduce low-pitch ranges despite good group delay characteristic, and outstanding waveform reproducibility can be achieved by covering the periphery of the speakers with sound-absorbent material so as to remove noise emitted by surfaces other than the front surface of cone paper.

Claim (Index 4):
An audio device comprising:\n an amplification device part which an audio signal from a sound source is input into and performs required processing and amplification of the audio signal; and a speaker device which is connected to the amplification device part and inputs the processed and amplified audio signal and outputs this audio signal; wherein the amplification device part includes a correction device which corrects at least one of a group delay characteristic, a frequency characteristic of the speaker device or an acoustic characteristic of a room in which the audio device is installed; a channel divider device that divides the audio signal into a plurality of frequency ranges and outputs the audio signal; and a plurality of amplification device which the plurality of divided audio signals are input respectively into, and amplifies and outputs the plurality of divided audio signals respectively; and the speaker device of  claim 2  is used as the speaker device.
