Embodiment
In order to be illustrated more clearly in the technical solution of the utility model, below in conjunction with drawings and Examples, the technical solution of the utility model is further elaborated, apparently, the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other embodiment can also be obtained according to these embodiments.
With reference to Fig. 1 and Fig. 5, a kind of side enabling sound proof box, comprises the casing 1 for putting audio test fixture 9, chamber door 2, and chamber door 2 is articulated and connected in the side of casing 1 by hinge 3; The separate space of audio-frequency test is configured for after casing 1 and chamber door 2 fasten.
With reference to Fig. 4, casing 1 comprises outer sound-proof wall body 11 and internal layer sound-proof wall body 13 and is provided with air barrier 12 between outer sound-proof wall body 11 and internal layer sound-proof wall body 13; Chamber door 2 comprises outer soundproof door 21 and internal layer soundproof door 23 and is provided with air barrier 22 between outer soundproof door 21 and internal layer soundproof door 23.Outer sound-proof wall body 11 and outer soundproof door 21 adopt high-strength material to make, and to form the force structure of sound proof box, general sheet metal or the composite panel of adopting makes.Internal layer sound-proof wall body 13 and internal layer soundproof door 23 adopt sound-insulation and sound-absorbing material to make, and are the primary structures intercepting sound transmission.Internal layer sound-proof wall body 13 and internal layer soundproof door 23 are at least made up of one deck sound-insulation and sound-absorbing material, also can be composited by the sound-insulation and sound-absorbing material that multilayer is different.Concrete structure can be selected according to actual needs, does not do too much restriction here.
With reference to Fig. 2 and Fig. 5, engaging support mechanism 4 is provided with between casing 1 and chamber door 2, engaging support mechanism 4 comprises the rotatable handle 41 that is arranged on chamber door 2 and is arranged on the buckling base 42 that casing 1 opposite position can be interlocked with handle 41, handle 41 is provided with one and can follows the fixture block that handle 41 rotates change position, buckling base 42 offers the bayonet socket matched with this fixture block, rotating handles 41 makes fixture block snap in bayonet socket, chamber door 2 is closely interlocked with casing 1, forms the separate space can carrying out audio-frequency test; When needing to open sound proof box, rotating handles 41 makes fixture block depart from bayonet socket, chamber door 2 can be opened.
In one embodiment, with reference to Fig. 4, because the interference of the action of audio test fixture 9 and external environment can make sound proof box shake when product is tested in sound proof box.For this reason, between the outer sound-proof wall body 11 of casing 1 bottom surface and internal layer sound-proof wall body 13, be provided with damping elastic piece (not shown), to prevent from occurring between outer sound-proof wall body 11 and internal layer sound-proof wall body 13 that the test of noise interference tones occurs in collision.Concrete, this damping elastic piece adopts damping spring.Damping spring also can be arranged in the side of casing 1, reduces the side direction unusual fluctuation of sound proof box as much as possible to the impact of casing 1 close beta activity.
In one embodiment, because sound proof box has certain weight, directly move and there is certain difficulty, the fortuitous event such as also easily collide with in handling process simultaneously, easily causes damage to the audio test fixture 9 of sound proof box inside and sound-insulation and sound-absorbing material layer.For this reason, with reference to Fig. 3, Height Adjustable castor (not shown) and Rubber shock-absorbing pad 6 bottom casing 1, is provided with.It is stressed that sound proof box puts down castor when storage configuration or carrying, protection Rubber shock-absorbing pad 6.When sound proof box carries out audio-frequency test, for avoiding external environment to the interference of sound proof box as far as possible, castor is packed up and is placed in vacant state, make Rubber shock-absorbing pad 6 stressed, by Rubber shock-absorbing pad 6, sound proof box is placed on the table, ensure the stable of test environment.
In one embodiment, sound proof box is just for audio-frequency test provides a test environment relatively not having noise jamming, and product is seated in audio test fixture 9 in sound proof box, needs to set up to contact to test macro just can carry out corresponding test activity.For this reason, with reference to Fig. 3, casing 1 is provided with the shielded joint 7 for connecting between audio test fixture 9 and outer testing system and waveguide 8, power by shielded joint 7 and waveguide 8 pairs of sound proof boxs and setting up data cube computation between sound proof box and test macro, send test command and output test data.
In one embodiment, casing 1 and the hinged of chamber door 2 cover the weakness that face is the integral sealing of sound proof box, due to the factor such as mismachining tolerance and use, the face that covers of casing 1 and chamber door 2 can not fit tightly, and has a strong impact on the overall soundproof effect of sound proof box.For this reason, with reference to Fig. 4, the height of the internal layer sound-proof wall body 13 of casing 1 forms interior step 14 lower than outer sound-proof wall body 11, the internal layer sound-proof wall body 13 of chamber door 2 protrudes the projection 24 being formed and abut against with step 14 in casing 1 to casing 1 direction, effectively reduce the adaptation of casing 1 and chamber door 2 junction, to ensure soundproof effect.Preferably, the interior step 14 of casing 1 is provided with soft adhesive tape with the place of abutting of the projection 24 of chamber door 2, fills the gap that may exist between casing 1 and chamber door 2, to ensure the integral sealing of sound proof box by the strain of soft adhesive tape.In other embodiments, interior step 14 quantity of casing 1 does not limit, and can increase and decrease according to actual needs, the projection 24 of chamber door 2 also carries out corresponding increase and decrease, form multiple sealing surface, improve the integral sealing of sound proof box as much as possible, obtain better soundproof effect.
In one embodiment, see figures.1.and.2, sound proof box needs adjust placement location on the table or carry out short-range moving, if put down by castor, need to carry out the operations such as leveling, comparatively lose time.For this reason, casing 1 both sides are symmetrically arranged with two handles 5 respectively, to facilitate the movement of sound proof box.
The structure that the utility model adopts multi-layer box to overlap intercepts layer by layer to sound, one is formed substantially not by the separate space that ambient noise affects in sound proof box, set up data cube computation by audio test fixture and shielded joint and waveguide and test macro, guarantee the accuracy of audio-frequency test process and result; Relative to the special soundproof room of construction, of the present utility model simple and compact for structure, volume is little, easy to operate, make and use cost cheap, be particularly suitable for the audio-frequency test of applying or carrying out in research and development of products trial-production and small batch production process to be correlated with in medium and small micro-enterprise.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
