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.
This application is a Continuation application of U.S. application Ser. No. 15/835,051 filed Dec. 7, 2017, which itself claims priority to Chinese App. No. 201611127617.5 filed Dec. 8, 2016, the disclosures and teachings of which are incorporated herein by reference.
TECHNICAL FIELDThe present invention relates to an anti-vibration device for sound equipment and a sound equipment rack with an anti-vibration device, and in particular, to an anti-vibration device which is used for reducing the consonance and resonance of sound equipment and of a laminate plate supporting the sound equipment and which has an elastic stress frame, and a sound equipment rack with an anti-vibration device.
BACKGROUNDThe case of sound equipment and the laminate plate supporting the sound equipment have similar characters with a musical instrument room, and when the sound equipment and the laminate plate supporting the sound equipment are played, struck or subjected to sound waves, vibrations, etc., they generate different levels of consonance and resonance under different conditions. Under the influence of the consonance and resonance, the sound equipment and the laminate plate supporting the sound equipment will no longer maintain their original static, quiet and stable normal working state, and will generate consonance and resonance, so that the sound equipment will output a distorted sound.
Conventionally, feet and pads for supporting the sound equipment are made of a hard material, and when they are used to support the sound equipment, since the contact area between the foundations and pads and the sound equipment is large, they cannot prevent the consonance and resonance from influencing the sound equipment. When vibration comes, the sound equipment will generate resonance and consonance and output a sound distorted greatly.
SUMMARYThe present invention provides for an anti-vibration device which is used for reducing consonance and resonance and has an elastic stress frame, and a sound equipment rack with an anti-vibration device. By applying the elastic stress frame to the case of a sound equipment and/or the laminate plate supporting the sound equipment in advance, which is similar to applying a suitable stress at the center of the cavity, the stable internal stress thereof is utilized to allow the case of the sound equipment and/or the laminate plate supporting the sound equipment to maintain their original position and state as much as possible, so that they cannot generate consonance and resonance, reducing the degree of distortion of the sound equipment.
The elastic stress frame produces a long-term stable internal stress in the following two ways. The first one is that the sound equipment is applied to the elastic stress frame, and produces, with its own weight, downward pressure on the elastic stress frame, so that the elastic stress frame is deformed and produces a long-term stable internal stress. The second one is that the elastic stress frame is mechanically locked, by means of screw fastening, onto the outside of the sound equipment to apply threaded fastening pressure on the sound equipment, so that the elastic stress frame is deformed and produces a long-term stable internal stress.
This results in high requirements for the material that makes the elastic stress frame. Firstly, the material used to make the elastic stress frame should have sufficient strength to support the weight of the sound equipment itself. Secondly, the material used to make the elastic stress frame should have proper elasticity to produce certain elastic deformation when applied to the sound equipment.
