Anti-vibration device for an acoustic device and an audio equipment frame having an anti-vibration device

Abstract

An anti-vibration device for sound equipment includes an elastic stress frame, the elastic stress frame including a stress deformation portion and a plurality of support portions, the support portions protruding toward one side with respect to the stress deformation portion. The anti-vibration device prevents most resonance from intruding into the sound equipment, the elastic stress frame and the laminate plate for supporting the sound equipment, and the sound equipment can work stably without being influenced by sound waves and resonance, so as to achieve its own due performance, naturally reducing the distortion rate of outputted sound.
