Further, described damping device includes fixing the damper cap of connection with housing bottom, can gliding in relative damper cap
Dynamic base bucket and be arranged on damper cap and the elastic compression assembly within base bucket；
Further, the inner periphery of described damper cap is provided with spacing slip ring, the excircle of described base bucket is provided with
The limit baffle ring suitable with spacing slip ring, described spacing slip ring can the excircle of respect thereto bucket slide up and down；
Further, described elastic compression assembly includes that middle part is threaded first baffle plate in hole, is arranged on base drum head
The second baffle in portion, the spring being clamped between the first baffle plate and second baffle, it is fixedly installed on the stud in the middle part of damper cap, institute
The corresponding threaded holes stating stud and the first baffle plate closes；
Further, the lower end adhesion of described base bucket has rubber blanket；
Further, described enclosure interior is filled with acoustical cotton.
This utility model at least has the advantages that
1, to can be used to absorb voice box casing by the combination application of orifice plate and black egg acoustical cotton low for this utility model
Frequently the standing wave that leader tape goes out, plays the effect of low frequency noise reduction；
2, damping device can effectively prevent audio amplifier from passing to user by ground when shaking, it is to avoid user is regarded by it
Sense of hearing is affected；
3, damping device can carry out the regulation of elastic force by the cooperation of stud and the screwed hole of the first baffle plate；
4, fill acoustical cotton by enclosure interior and can improve the sounding quality of audio amplifier further；

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model preferred embodiment is illustrated:
As illustrated in fig. 1 and 2, a kind of passive loudspeaker box with shock-absorbing denoising function, including square casing and be arranged on housing 1
On loudspeaker, described housing 1 inwall is provided with denoising device, described housing bottom is provided with damping device；Described noise reduction fills
Put include the fixing orifice plate 2 being fitted on the back plate of housing 1, side plate, top board and plate inner wall and stick in outside orifice plate 2 black
Color egg acoustical cotton 3；Described orifice plate 2 material is plank, and thickness is 9mm or 11mm, and aperture that orifice plate 2 gathers is 5～10mm
Through hole；The thickness of described black egg acoustical cotton 3 is 3mm or 5mm；Described damping device includes be connected fixing with housing 1 bottom
Damper cap 4, can damper cap 4 slides up and down relatively base bucket 5 and be arranged on elastic internal with base bucket 5 of damper cap 4 and press
Contracting assembly；It is provided with spacing slip ring 6 on the inner periphery of described damper cap 4, the excircle of described base bucket 5 is provided with spacing
The limit baffle ring 7 that slip ring 6 is suitable, described spacing slip ring 6 can the excircle of respect thereto bucket 5 slide up and down；Described elastic pressure
Contracting assembly includes that middle part is threaded first baffle plate 8 in hole, is arranged on the second baffle 9 bottom base bucket 5, is clamped in first
Spring 10 between baffle plate 8 and second baffle 9, it is fixedly installed on the stud 11 in the middle part of damper cap 4, described stud 11 and first gear
The corresponding threaded holes of plate 8 closes；The lower end adhesion of described base bucket 5 has rubber blanket 12；Described housing 1 is internal is filled with acoustical cotton.
In this utility model: housing 1 is square, it is made up of header board, back plate, top board, base plate and side plate totally six allegros, its
Middle header board is mainly used in placing loudspeaker, and loudspeaker can be resonant horn, off-resonance loudspeaker or the combination of two kinds of loudspeaker, it is contemplated that
The problem installing or using resonant horn of loudspeaker, in addition to header board does not installs denoising device, denoising device is installed in remaining plate face,
The length and width of orifice plate 2 are dimensioned slightly smaller than the length and width size in its space, place, in order to the adhesion of black egg acoustical cotton 3 is advisable；Adopt
