For the present invention in view of the above-mentioned problems, providing a kind of producing line loudspeaker test silencer box, the silencer box occupied ground is small, and
And it conveniently operates with.
The technical scheme is that：A kind of producing line tests silencer box, the cabinet including upward opening, the case with loudspeaker
The inner wall of body is fixed with acoustical cotton；The opening of the cabinet is hinged with cover board, and loudspeaker placing groove is provided on the cover board.
Further, handle is installed on the cover board.
Further, lock is installed between the cover board and the cabinet.
Further, the cabinet includes bottom plate, and foreboard, back plate and two blocks of side plates are connected on the bottom plate.
Further, the bottom plate, the foreboard and the back plate are rectangle, and the side plate is right-angled trapezium；It is described
The foreboard and back plate is wide and the length of the foreboard is less than the back plate, the foreboard are parallel to the back plate and described
Foreboard intersects with bottom plate inclination with the back plate；The side plate perpendicular to the bottom plate and the right-angled trapezium it is oblique
Waist edge is connected with the bottom plate.
Further, the angle between the foreboard and the back plate and the bottom plate is 75 °.
Further, the material of the cabinet and the cover board is high density bakelite plate.
Further, the high density bakelite plate with a thickness of 20mm.
Further, the acoustical cotton with a thickness of 50mm.
The technical effects of the invention are that：Cover board is hinged on the opening of cabinet by the present invention, and loudspeaker is arranged on the cover board
Loudspeaker can be fixed rapidly, greatly improve production efficiency by placing groove；Cover plate of the present invention tilts phase with horizontal plane
It hands over, worker operation is facilitated to use；The present invention is small in size, and isolation is high, easy to use.
Detailed description of the invention
Fig. 1 is schematic perspective view of the invention.
Fig. 2 is left view of the invention.
In Fig. 1, Fig. 2, including cabinet 1, hinge 2, cover board 3, loudspeaker placing groove 4, handle 5, lock 6, bottom plate 7, back plate 8,
Side plate 9, foreboard 10.
Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1 and Figure 2, the present invention is a kind of producing line loudspeaker test silencer box, the cabinet 1 including upward opening with
The cover board 3 of 1 opening of cabinet is hinged on by hinge 2.The material of cabinet 1 and cover board 3 is high density bakelite plate, high density bakelite
Plate with a thickness of 20mm.The cabinet 1 is according to acoustic characteristic design size, and all sizes pass through sound field design, to reach most
Good test effect.
Cabinet 1 is made of bottom plate 7, foreboard 10, back plate 8 and side plate 9.Foreboard 10, back plate 8 and two pieces are connected on bottom plate 7
Side plate 9.
Bottom plate 7, foreboard 10 and back plate 8 are rectangle, and side plate 9 is right-angled trapezium；Foreboard 10 and back plate 8 is wide and foreboard 10
Length be less than back plate 8, foreboard 10 is parallel to back plate 8 and foreboard 10 and back plate 8 tilt with bottom plate 7 and intersect；Side plate 9 is vertical
It is connected in the oblique waist edge of bottom plate 7 and right-angled trapezium with bottom plate 7.Angle between foreboard 10 and back plate 8 and bottom plate 7 is 75 °.
The inner wall of cabinet 1 is fixed with acoustical cotton, acoustical cotton with a thickness of 50mm.
Cover board 3 is also rectangle, and cover board 3 is vertical with foreboard 10, back plate 8 and side plate 9 respectively after covering.Due to foreboard 10 and after
Angle between plate 8 and bottom plate 7 is 75 °, therefore the angle between cover board 3 and bottom plate 7 is 15 °.Cover board 3 tilts phase with horizontal plane
It hands over, worker operation is facilitated to use.
It is provided with loudspeaker placing groove 4 on cover board 3, can rapidly fix loudspeaker.Handle 5 is installed, with side on cover board 3
Just cover board 3 is opened.Lock 6 is installed, for locking cover board 3 between cover board 3 and cabinet 1.
The present invention is suitable for the acoustical testing of toy trumpet (horn diameter is less than 50mm).In use, loudspeaker are fixed on lid
Microphone (micphone) is placed in inside cabinet 1 by the loudspeaker placing groove 4 on plate 3, and such loudspeaker front sounding passes through
Micphone receives its sound, tests its effect.
The present invention is small in size, and isolation is high, can quickly fix loudspeaker, greatly improve production efficiency.
Finally it should be noted that：The foregoing is merely the preferred embodiment of the invention patent, it is not limited to this
Invention, although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, according to
It is so possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is equally replaced
It changes, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in the present invention
