Specific embodiment
Referring to shown in Fig. 1-Fig. 5, present embodiment the technical solution adopted is that: it includes packing layer 1, vacuum glassLayer 2, air bag layer 3, damping layer 4, described filler layer 1 are connect with hollow glass layer 2, and the vacuum glass layer 2 connects with air bag layer 3It connects, the air bag layer 3 is connect with damping layer 4, and described filler layer 1 includes noise reducing plate 11, honeycomb paper base 12, the noise reducing plate 11Be pasted onto the outside of honeycomb paper base 12 by binder, the air bag layer 3 includes soundproof plate 31, buffer air bag 32, it is described everyMultiple buffer air bags 32 are provided on soundboard 31, the buffer air bag 32 is in the inside of truncated cone-shaped and buffer air bag 32 filled with dropIt makes an uproar filler 33, the damping layer 4 is internally provided with damping rubber 41.
The outside even adhesion of described filler layer 1 has multiple electromagnetic wave generators 5, the outside of the electromagnetic wave generator 5It is bonded with polyurethane foam plastics plate 6, electromagnetic wave generator 5 is mounted between packing layer 1 and polyurethane foam plastics plate 6, is gatheredUrethane plastic foamboard 6 can play good Noise Reduction, while extraneous sound wave triggers first before entering packing layer 1Electromagnetic wave generator 5 issues electromagnetic wave, and the electromagnetic wave that electromagnetic wave generator 5 issues is offseted with extraneous sound wave, thusCarry out the noise reduction of preliminary noise.
Pass through the binder connection of 12 inside of honeycomb paper base, the honeycomb between described filler layer 1 and vacuum glass layer 2Sound-proof material 13 is filled with inside official form for filing a lawsuit base 12, the two sides of honeycomb paper base 12 are respectively by close with noise reducing plate 11, vacuum glass layer 2Envelope connection, is capable of forming closed air layer, can play the role of sound insulation, while the sound insulation filled inside honeycomb paper base 12Cotton 13 can further be isolated noise, effective to carry out noise reduction sound insulation.
It is connected between the vacuum glass layer 2 and air bag layer 3 by buffer air bag 32, the round platform top of the buffer air bag 32Portion is connect with vacuum glass layer 2, and the rotary table bottom of buffer air bag 32 is connect with soundproof plate 31, and the inside of the buffer air bag 32 is filled outThe noise reduction filler 33 filled is silica dioxide gel, when sound wave enters air bag layer 3, the buffer air bag 32 of truncated cone-shaped can to sound wave intoRow absorbs, and the silica dioxide gel filled inside simultaneous buffering air bag 32 further can effectively absorb sound wave, reachesTo the purpose of further noise reduction.
The damping layer 4 include noise reduction column 42, abatvoix 43, the noise reduction column 42 be hollow cylinder, the two of noise reduction column 42Side is embedded in the inside of abatvoix 43 Yu soundproof plate 31 respectively, when sound wave is passed to the hollow cylinder of noise reduction column 42 can to sound wave intoRow barrier.
The noise reduction column 42 is provided with multiple, and the outside of noise reduction column 42 is enclosed with damping rubber 41, the damping rubber 41For the one of which in polyacrylate, polyurethane, epoxy resin, butyl rubber or nitrile rubber, by dropping from the air in being wrapped inMake an uproar the outside of column 42 damping rubber 41 sound wave can be carried out it is further absorb barrier, select polyacrylate, polyurethane, ringOxygen resin, butyl rubber or nitrile rubber are low in cost as damping rubber 41, convenient for promoting.
The outside of the damping layer 4 is provided with installation sheet 7, and the installation sheet 7 is in sucker, adhesive layer or fixed sea whelkOne of which, by installation sheet 7 can by device it is convenient and simple be fixed on window, at around window or room noise source, fromAnd noise reduction process is carried out to room noise.
The working principle of the invention: in use, device is mounted on window by installation sheet 7, around window or room noiseAt source, when installation, need to be by the side of polyurethane foam plastics plate 6 towards noise source, when the sound wave of noise is sent, firstIt triggering electromagnetic wave generator 5 and issues electromagnetic wave, the electromagnetic wave that electromagnetic wave generator 5 issues is offseted with extraneous sound wave,The noise reduction of preliminary noise is carried out, the honeycomb paper base 12 and sound-proof material 13 that subsequent sound wave enters in packing layer 1 carry out sound insulation and dropIt makes an uproar；When sound wave enters vacuum glass layer 2, the transmission of barrier sound wave is carried out by the sound damping of vacuum glass layer 2；In sound waveWhen into air bag layer 3, the buffer air bag 32 of truncated cone-shaped can absorb sound wave, two filled inside simultaneous buffering air bag 32Silica gel further can effectively absorb sound wave；When sound wave enters damping layer 4, pass through hollow noise reduction column 42With the transmission that can obstruct sound wave under the collective effect of damping rubber 41, finally by 43 sound-absorbing of abatvoix, device is by making an uproarSound carries out sound insulation, absorption, barrier, can effectively reduce room noise, builds quiet comfortable living environment for user.
The above is only used to illustrate the technical scheme of the present invention and not to limit it, and those of ordinary skill in the art are to this hairThe other modifications or equivalent replacement that bright technical solution is made, as long as it does not depart from the spirit and scope of the technical scheme of the present invention,It is intended to be within the scope of the claims of the invention.
