To solve a significant problem in installation work when an audio insulator is applied to an audio apparatus in which, for example, when a spike is installed in a heavyweight speaker, the work of fitting an axis of the spike of the speaker to one of a spike receiver of a floor face is not easy, so that the heavy labor work in which two or more hands are essential is released, the insulator is safely, simply installed, and evaluation of acoustic characteristics of the insulator which is easily controlled by an audience's mental factors (placebo effect) is quickly, precisely carried out.
In this structure, an audio apparatus 100 is mounted on a lifter 101 to raise the lifter 101, thereby increasing a distance of a base of the audio apparatus and the floor face to install the insulators 103a and 103b detachably, and also this distance is decreased, thereby installing the lifter 101 detachably in a state in which own weight of the audio apparatus 100 is supported by only the insulators 103a and 103b.
