Abstract

PURPOSE:To minimize oscillation and to improve an acoustic performance by providing many supporting columns including an oscillation absorber to the section of opposing surfaces of a chassis and an acoustic recording and reproducing part. CONSTITUTION:To an air propagation sound and the oscillation due to the solid propagation to be generated in the internal part of a device, the rigidity of the chassis can be widely increased, and the resonance can be prevented by many supporting columns 12 including an oscillation absorber 14 arrange between a chassis 4 and an acoustic recording and reproducing part 1. A remaining oscillation is further reduced by an oscillation absorber 14. Thus, without generating inherent noise, the oscillation can be widely reduced while a high rigidity is held, and even a solid oscillation component coming from an external part, an oscillation component to be generated in the internal part and an air propagation sound to be generated by a speaker, etc., exist, a quiet acoustic recording and reproducing device can be obtained.
