PURPOSE:To aviod an effect to speaker vibrations, by supporting an audio rack with a vibration-resistant tool. CONSTITUTION:An audio device contains a speaker box which is set adjacent to an audio rack 5 containing audio devices such as a record player, a turner, an amplifier, etc. A vibration-resistant tool of such an audio device consists of a chevron supporter 9 of an elastic material (rubber) having a hollow inside part and a coil spring 10 and supports the rack 5 springily. The vibration mode differs by the type of the floor substance (plywood, straw matting, concrete, etc.) on which the rack 5 is installed and the installation conditions of the rack 5. Therefore it is possible to aviod a effect of speaker vibrations to the rack 5 by having an adjustment in response to the vibrating characteristics of the floor substace. Thus, the generation of howling is prevented in case of playing a record player. |
