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 2):
A multi-way type speaker device:\n wherein a reproduction frequency range is divided into a plurality of frequency ranges and each frequency range is reproduced by each separate assigning speaker, and comprising:\n an assigning speaker that reproduces a low frequency range among a plurality of assigning speakers constituting the multi-way type speaker and obtained by setting a single speaker having a small-diameter and ability insufficient to reproduce the low frequency as a single speaker unit and combining a plurality of speaker unit, and \n a sound-absorbent member which covers a part of the speaker box other than a front surface facing the hearing direction of a vibrator such as cone paper or the like which emit a sound of each unit speaker for preventing emission of noise and emitting only a signal sound, when a sound emitted from the front surface of the vibrator such as cone paper or the like of each unit speaker, is called the signal sound and \n a sound other than the signal sound including a sound emitted from a back surface of the vibrator such as cone paper or the like and a sound generated from an object such as a speaker box or the like which is in contact with the speaker unit and vibrated accompanied by a vibration of the vibrator, is called a noise.
