Description
Technical field
The present invention relates to a kind of shielded box, more particularly to a kind of larger type speakers shielded box.
Background technology
Loudspeaker serves not only as the important means that electronic equipment interacts with people, and creates necessity of high-quality music
Hardware.In the attribute test of loudspeaker, particularly larger type speakers are easily disturbed caused by its characteristic by external sound,
It must be carried out under a metastable, quiet sound field.The inspection of dispatching from the factory of specialty must be passed through after the loudspeaker produced
Survey could be sold, and in this link, general factory can all set special test room, using equipment such as soundproof walls, although energy
The decay of sound is reduced to a certain extent, improves the quality of detection, but because test room is excessive, also easily cause reverberation, shadow
Detection quality is rung, while the room of test occupies substantial amounts of space on the spot, adds job costs, and test job personnel are in room
During interior operation, certain injury is easily caused to itself ear-drum.Some producers are detected to reduce cost using box-type, but
High integration and the consideration to cost are excessively pursued, have ignored accuracy of detection and convenience.
The content of the invention
The technical problems to be solved by the invention are overcome the deficiencies in the prior art, there is provided a kind of portable construction, are consolidated
Larger type speakers shielded box that is durable and possessing good sound insulation value.
The technical solution adopted in the present invention is：The present invention includes casing and chamber door, the casing include inner shield case with
External shield case, the inner surface of the internal layer shielded box is covered with sound absorption wedge, between the inner shield case and the external shield case
The both sides for being provided with sound panel and the sound panel are provided with fireproof environmental Sound-proof material, and the inner shield case is internally provided with folder
Have mounting seat, connection panel is provided with the casing.
Further, the external shield case includes upper plate, lower shoe, right baffle-plate, right shell body, front apron and rear baffle, and
The upper plate, the lower shoe, the right baffle-plate, the right shell body, the material of the front apron and the rear baffle are
International high-quality cold-rolled steel sheet.
Further, the chamber door is arranged at the middle part of the front apron and the side of the chamber door is cut with scissors with the front apron
Connect, the opposite side of the chamber door is provided with sealing handle, and the front apron be provided be adapted with the sealing handle it is close
Closure.
Further, the outer surface of the external shield case is covered with nylon protection network.
Further, the lower shoe is provided with castor, and the castor is provided with rotary extension foot pad.
Further, the right baffle-plate and the right shell body are provided with pushing handle.
The beneficial effects of the invention are as follows：Because the present invention includes casing and chamber door, the casing is including inner shield case and outside
Shielded box, the inner surface of the internal layer shielded box are set covered with sound absorption wedge between the inner shield case and the external shield case
The both sides for being equipped with sound panel and the sound panel are provided with fireproof environmental Sound-proof material, and the inner shield case is internally provided with fixture
Mounting seat, be provided with connection panel on the casing, so, the present invention is used for the acoustical testing of larger type speakers, possess compared with
Good sound insulation capabilities, the noise jamming in the external world can be isolated, the sound sent, protection behaviour can be tested with damp internal loudspeaker again
The sense of hearing of work person.The outgoing characterization processes step being usually applied on loudspeaker production line, can substitute traditional sound insulation
Room, producing line cost can be substantially reduced, lift testing efficiency, save producing line space, and use multiple sound insulation structure, structure is light
Just, it is firm durable, possess good sound insulation value.Innermost layer uses high-quality acoustical cotton wedge, can effective sound-absorbing, reduce case in
Sound reflection, the sound field environment of relative ideal is provided for loudspeaker test.
