Abstract

<p>Audio insulators used widely among audio users are convenient to control the reproduced sound under audio equipment despite the difference in their material and shape. However, there are no theoretical analysis of those works and effects. In this study, to clarify the works of common circular cone used as insulator, its vibration transmission characteristics is evaluated by driving impedance at input by using four-terminal matrix of insulator after describing its input-output by an equivalent circuit. Consequently, we could clarify that the circular cone has a changing frequency point to pass through or insulate the vibration related with material and shape. This tendency is also confirmed experimentally by measuring the attenuation of vibration velocity between input and output ends of them. Moreover, this method is also effective for composite structure to design the vibration transmission characteristic of entire system. This selective transferring characteristic will be useful to eliminate or insulate inevitable vibration.</p>
