Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of elevator noise reduction sedan-chair wall as Figure 1-Figure 4, including inwall panel 1, outer cover plate 9 and rivet, the inwall
Acoustical panel is provided between panel 1 and the outer cover plate 9, the acoustical panel is included in the framework 5 and polylith Thin Elastic of matts shape
Film 6, is equipped with several bloops 7 on every piece of elastic film 6, have multiple rectangular openings on the framework 5, described in each
Be equipped with one piece of elastic film 6 in rectangular opening, the elastic film 6 perpendicular to the rectangular opening central axis, it is described
The rectangular opening is separated into two parts by elastic film 6；The framework 5 is including the metal frame 11 in matts shape and is covered in institute
The rubber layer 12 on the surface of metal frame 11 is stated, the rubber layer 12 and the elastic film 6 are integrally formed；The inwall panel 1
Trailing flank is provided with least two vertically extending reinforcements 2, and the rear lateral edge of at least two reinforcements 2 is provided with
Flange 3, is equipped with the first riveted holes 4 on the flange 3, the framework 5 is provided with one-to-one with first riveted holes 4
Second riveted holes 8, the outer cover plate 9 is provided with and one-to-one 3rd riveted holes 10 of first riveted holes 4, the rivet
Coordinate through the 3rd riveted holes 10 and second riveted holes 8 and with first riveted holes 4, by the acoustical panel and
The outer cover plate 9 is fixed on the reinforcement 2.Above-mentioned metal frame 11 can be made up of hard metals such as aluminium alloy, steel.
Using said structure, the polylith elastic film 6 on acoustical panel forms multiple locally resonant units, elastic film 6
Middle part it is hanging, can the front and rear vibration in corresponding rectangular opening, the weight and elasticity of elastic film 6 itself can constitute quality-bullet
Spring resonator system, and with certain intrinsic frequency, when the noise of the frequency range near this intrinsic frequency passes through acoustical panel
When causing the vibration of acoustical panel, elastic film 6 can also occur locally resonant and produce reaction force to whole acoustical panel, and counteracting disappears
The vibration of soundboard, the vibration of whole acoustical panel is inhibited, so as to reduce the acoustic wave energy continued to external radiation.Due to elasticity
Rectangular opening is separated into two parts by film 6, and elastic film 6 and rectangular opening form two-layer Helmholtz resonators.Bloop 7
Air composition quality-spring resonance system in interior air and the first cavity 8, air and Thin Elastic in the second micropunch 7
The air of the both sides of film 6 separately constitutes quality-spring resonance system, in the resonant frequency range of the quality-spring resonance system
Noise pass through bloop 7 when, the resonance of cavity will be produced, so as to absorb the energy of sound wave, play a part of sound insulation.Together
When, there is metal frame 11 in framework 5, framework 5 is clamped in when between inwall panel 1 and outer cover plate 9, and fixes company by rivet
It is connected together, attachment structure is simple and reliable, and metal frame 11 can play good supporting role, can be prevented effectively from inwall
Panel 1 is recessed backward, simultaneously because the surface of metal frame 11 is coated with rubber layer 12, rubber layer 12 can play cushioning effect,
Avoid in running process of elevator, knocked between framework 5, inwall panel 1 and outer cover plate 9.
Further, the bloop 7 with least two different pore sizes on every piece of elastic film 6.Different pore size
The bloop different noise frequencies of correspondence, the noise of multiple frequency range can be eliminated.
As one kind preferably, the elastic film 6 and the rubber layer 12 are formed in the gold by way of injection
On category frame 11.
Further, filled with silencing cotton layer between the acoustical panel and the inwall panel 1, to strengthen soundproof effect.
