Detailed Description

It is right to refer to fig. 1 to 4 to refer to the utility model relates to a novel sound-proof glass based on actively make an uproar falls passively. The examples are further illustrated.

The utility model provides a novel soundproof glass based on actively falling and passively falling makes an uproar, see figure 1, including leading glass panels 1 and rearmounted glass panels 6, is equipped with multilayer noise insulation mechanism between leading glass panels 1 and the rearmounted glass panels 6, and between the adjacent noise insulation mechanism and the noise insulation mechanism be close to all be equipped with vacuum chamber 7 between one side of leading glass panels 1 and one side of rearmounted glass panels 6, be equipped with the unit of falling of initiative noise 3 in the noise insulation mechanism. When the device is not electrified, the separation of sound waves on the physical layer is realized by utilizing the vacuum chamber 7 between the sound insulation mechanisms, and when the device is electrified, the active noise reduction unit 3 is utilized to generate sound waves with the same amplitude and the opposite phase as the noise source, so that the sound waves and the noise source sound waves are offset in space superposition.

See fig. 1, the sound-proof mechanism includes leading syllable-dividing closing plate 2, the initiative is fallen and is made an uproar closing plate 4 and rearmounted syllable-dividing closing plate 5, leading syllable-dividing closing plate 2 passes through sealing strip and leading glass panels 1 fixed connection, leading syllable-dividing closing plate 2 deviates from one side of leading glass panels 1 and the initiative is fallen and is made an uproar closing plate 4 fixed connection, the initiative is fallen and is made an uproar closing plate 4 and deviate from one side of leading syllable-dividing closing plate 2 and rearmounted syllable-dividing closing plate 5 fixed. A plurality of vacuum chambers 7 are formed among the front glass panel 1, the front sound insulation sealing plate 2, the active noise reduction sealing plate 4, the rear sound insulation sealing plate 5 and the rear glass panel 6, and the plurality of vacuum chambers 7 improve the effect of sound volume separation.
