Insulator for audio and method for evaluating same

摘要

In a conventional hard material insulator, reproduced sound can be tuned with use of characteristics of the material; however, various types of acoustic materials have specific high frequency characteristics, and thus their acoustic effects lack versatility, require compatible audio devices, and change with environment, musical genre, etc. To address this, a wind-bell member (resonant member) is arranged in parallel with a main propagation path of vibration transferred from an audio device to an insulator. Accordingly, a vibration system of a wind-bell having a tone determined by many factors such as a fundamental tone, harmonic tones, lingering sound, and fluctuation assists (enhances) high frequency vibration propagated from the audio device. As a result, due to the above assist action that is different in principle from a conventional type, acoustic characteristics such as a sense of localization, resolution, and a sense of transparency and scale a sound image can be dramatically improved.

主权项

1. An insulator for audio comprising:
an elastic member that is held between an upper support member and a lower support member and supports a load of an audio device; and a resonant member formed as the upper support member or separately therefrom that has a plurality of resonance points in a frequency range that is higher than a resonance frequency that is defined by a mass of the audio device and a static stiffness of the elastic member, wherein the resonant member is arranged in parallel with the elastic member such that, given that vibration propagated from the audio device toward the elastic member is main vibration, vibration of the resonant member is superimposed on the main vibration.
