Abstract
The utility model relates to a damping sound-absorbing material structure, specifically to a damping sound-absorbing material structure capable of reducing surface vibration of a structural member and absorbing noise around the structural member, which belongs to the vibration-reducing and noise-deceasing technical field. The damping sound-absorbing material structure includes rubber and sponge, wherein the sponge is bonded on the surface of the rubber. When the damping sound-absorbing material structure is used, the damping sound-absorbing material structure can be in two forms, namely, a damping sound-absorbing material structure with the outer side of the rubber being coated with an adhesive sticker, and a damping sound-absorbing material structure with the outer side of the rubber being not coated with the adhesive sticker. When the damping sound-absorbing material structure with the outer side of the rubber being coated with the adhesive sticker is used, only a release paper is only needed to torn off, and then, a damping sound-absorbing plate is directly bonded on the surface of the structural member. When the damping sound-absorbing material structure with the outer side of the rubber being not coated with the adhesive sticker is used, the surface of the structural member is needed to be coated with glue, and then, a damping sound-absorbing material is bonded on the surface of the structural member. The damping sound-absorbing material structure of the utility model which is of structural simplicity can effectively reduce the vibration of the structural member and absorb the noise around the structural member, thereby effectively reducing overall unit noise of machinery equipment.
Description
Technical field
The utility model relates to a kind of damping acoustic absorbant structure, specifically reduces the surface vibration of structural member, and the noise around the absorbing structure spare belongs to the noise reduction technology field.
Background technology
Raising along with development in science and technology and living standards of the people, people are more and more higher to the requirement of living environment and working environment, low noise to electronic product etc. requires more and more higher, the noise that the noise reduction of present existing noise reduction technology can't satisfy client's demand, particularly low-frequency range can not well reduce.Existing damping material can only reduce the vibration of structural member, and acoustic absorbant can only absorbing structure spare noise on every side.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of novel damping acoustic absorbant structure is provided, and can effectively reduce vibration and the noise of electronic product full frequency band.
According to the technical scheme that the utility model provides, damping acoustic absorbant structure comprises rubber, sponge, and described sponge sticks on rubber surface.
Described rubber thickness is between 0.1mm～20mm.
Described sponge thickness is between 1mm～200mm.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, can effectively reduce the vibration of structural member, the noise around the absorbing structure spare, thus more effectively reduce the total noise of centrifuge of plant equipment.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, comprise rubber 1, sponge 2, described sponge 2 sticks on rubber 1 surface.
Described rubber thickness is between 0.1mm～20mm.Described sponge thickness is between 1mm～200mm.
During use, this damping acoustic absorbant structure has two kinds of forms, namely is coated with or is not coated with two kinds of adhesive stickers in the rubber outside.When using the rubber outside to be coated with the damping acoustic absorbant structure (plate) of adhesive sticker, need only tear release liners after, the damping acoustic board directly is attached to the structural member surface gets final product.When use is not coated with the damping acoustic absorbant structure (plate) of adhesive sticker, must behind structural member surface coating water, again the damping acoustic absorbant be sticked on the structural member surface.
