INSULATOR FOR AUDIO AND METHOD FOR EVALUATING SAME

摘要

In the case of a conventional hard material insulator, selecting a good quality acoustic material makes it possible to tune a reproduced sound using a character of the material. Since each type of acoustic material to be applied has a unique high-frequency characteristic, however, there are disadvantages that the effect is limited and depends on the compatibility with an audio device and the acoustic effect changes if the installation environment of an audio device, a genre of music, and other things are changed. In the present invention, a wind-bell member (resonance member) is disposed in parallel with a main transmission path of vibration transmitted from an audio device to an isolator. This allows the vibration system of a wind-bell having a tone determined by many factors including, for example, a root, a harmonic tone, afterglow, and fluctuation to assist (or strengthen) a high-frequency vibration transmitted from the audio device. As a result, the assist function different in principle from a conventional method can drastically improve the acoustic characteristics such as a sense of localization of a sound image, resolution, a sense of transparency, a sense of scale, etc.
