Abstract
The present utility model discloses a vibrating table arranged inside an anechoic room. The vibrating table is characterized in that a vibrating isolation device is arranged, and the vibrating isolation device comprises a sound insulation member arranged between the anechoic room and the vibrating table. Through arranging the vibrating isolation device on the vibrating table, the vibrating table and the anechoic room are mutually isolated, and background noises on the anechoic room and adverse influences on free sound field caused by vibration can be reduced to the greatest extent.
Description
Technical field
The utility model relates to a kind of shaking table that is installed in the anechoic room.
Background technology
In the acoustical testing process, sometimes need test products under shock conditions, to test, therefore need in (following take anechoic room as the example) test environments such as anechoic room, sound reducing enclosure or quiet room, place shaking table, carry out acoustical testing on the shaking table and test products is placed on.
With reference to Fig. 2, in the prior art, shaking table 20 normally is placed directly on the inside of anechoic room 22 so that the test products (not shown) is carried out acoustical testing; But because shaking table 20 itself can produce vibrations, these vibrations are passed on this body structure of anechoic room 22 easily so, can cause the background noise of anechoic room 22 and the deterioration of free found field.
The utility model content
The purpose of this utility model is for defects of the prior art, and a kind of shaking table that is installed in the anechoic room is provided, and it can reduce its vibrations to greatest extent to the harmful effect of the structure of anechoic room own.
For realizing above-mentioned utility model purpose, the utility model has adopted following technical scheme: a kind of shaking table that is installed in the anechoic room, it is characterized in that it is provided with the vibration isolation device, described vibration isolation device comprises the sound insulating member that is arranged between described anechoic room and the described shaking table.
In addition, the utility model also proposes following attached technical scheme:
Described shaking table comprises the bottom of main part and supportive body section.
Described vibration isolation device also comprises the beam of the lower surface that is arranged on the shaking table bottom.
Described sound insulating member is made by soft sound-proof material.
Described sound insulating member is arranged on the both sides of the bottom of shaking table.
Described anechoic room comprises base plate, and described base plate is provided with breach, and the bottom of described shaking table is installed in the described breach.
Described vibration isolation device also comprises rubber strip, and described rubber strip surrounds the bottom of described shaking table.
Than prior art, the utility model has the advantage of: shaking table is by arranging the vibration isolation device, so that mutually isolation and can reduce to greatest extent its vibrations to the background noise of anechoic room and the harmful effect of free found field between itself and the anechoic room.
Description of drawings
Fig. 1 is for being installed on the section plan in the anechoic room corresponding to the shaking table of the utility model preferred embodiment.
Fig. 2 is that shaking table of the prior art is installed on the section plan in the anechoic room.
Embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof technical solutions of the utility model are done further nonrestrictive detailed description.
With reference to Fig. 1, a kind of shaking table 3 in the anechoic room 1 of being installed on corresponding to the utility model preferred embodiment, it is provided with vibration isolation device 5, in order to reduce to greatest extent its vibrations to the harmful effect of 1 body structure of anechoic room.
This anechoic room 1 is also replaceable to be other acoustical testing environment such as sound reducing enclosure or quiet room, a plurality of beams 14 that it comprises base plate 12 and is installed in base plate 12 belows.The centre of base plate 12 is provided with breach 16.
Above-mentioned shaking table 3 comprises the bottom 34 of main part 32 and supportive body section 32.Be used for placing the tested product (not shown) on the main part 32.Bottom 34 places in the above-mentioned breach 16.
Described vibration isolation device 5 comprises the sound insulating member 52 that is arranged between described anechoic room 1 and the described shaking table 3, particularly, this sound insulating member 52 is installed in the both sides of the bottom 34 of shaking table 3, and is made by soft sound-proof material, so that shaking table 3 is mutually isolated with anechoic room 1 but not directly contacted.This vibration isolation device 5 also comprises beam 54 and rubber strip 56.Beam 54 is arranged on the lower surface 35 of the bottom 34 of shaking table 3; And described rubber strip 56 surrounds the bottom 34 of described shaking table 3, so that the isolating exterior noise is on the impact of shaking table 3.
As seen, of the present utility modelly be installed on shaking table 3 in the anechoic room 1 by vibration isolation device 5 is set, so that mutually isolate by sound-proof material between itself and the anechoic room 1, thereby can reduce to greatest extent its vibrations to the harmful effect of 1 body structure of anechoic room, and energy while isolating exterior noise is to the harmful effect of shaking table 3.
It is to be noted; above-mentioned preferred embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
