Abstract
The utility model provides an overlength stroke supersound projector magnetic conduction T iron, includes base plate (1) and cylinder (2), base plate (1) and cylinder (2) formula structure as an organic whole, the integral type structure for the forging and pressing formed part, base plate (1) position of being connected with cylinder (2) be equipped with ring groove (3), ring groove (3) be located the upper surface of base plate (1). This overlength stroke supersound projector magnetic conduction T iron can effectively reduce the error of perpendicularity of cylinder, makes the cylinder error of perpendicularity keep in the allowed band.
Description
Technical field
The utility model relates to loudspeaker techniques field, specifically refers to a kind of ultralong-stroke supersound projector magnetic conduction T iron.
Background technology
At present, comparatively common ultralong-stroke supersound projector magnetic conduction T iron is generally made up of cylinder and substrate, wherein column cap is crimped in the centre bore of substrate by the mode of riveted, and in riveted process, because cylinder whole height is high, column vertical degree error is large, and how the error of perpendicularity of effective guarantee cylinder, in allowed band, is those skilled in the art focus of always paying close attention to of row for this reason.
Utility model content
The technical problems to be solved in the utility model is, provides one effectively can reduce column vertical degree error, makes column vertical degree error remain on ultralong-stroke supersound projector magnetic conduction T iron in allowed band.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: comprise substrate and cylinder, described substrate and cylinder are integral type structure, described integral structure is for forging into shaped piece, the position that described substrate is connected with cylinder is provided with annular recess, and described annular recess is positioned at the upper surface of substrate.
The upper surface of described substrate is horizontally disposed with, and the lower surface of described substrate tilts and the thickness of substrate is thinning gradually to edge by center, and thickness effectively can reduce raw material by the substrate that center is thinning gradually to edge, reaches the object of province's material.
The central through hole of described cylinder is conical through-hole wide at the top and narrow at the bottom, and conical through-hole is convenient to airflow.
Ultralong-stroke supersound projector magnetic conduction T iron of the present utility model because of substrate and cylinder be integral type structure, and integral structure is for forging into shaped piece, the ultralong-stroke supersound projector magnetic conduction T iron of forging forming effectively can reduce the error of perpendicularity of highly high cylinder, column vertical degree error is made to remain in allowed band, improve the total quality of ultralong-stroke supersound projector magnetic conduction T iron, and arranging of annular recess is effectively thinned substrate and is connected with cylinder the thickness at position, avoid the generation of ultralong-stroke supersound projector magnetic conduction T iron sunburner phenomenon, facilitate forging forming.
Accompanying drawing explanation
Accompanying drawing is the sectional structure schematic diagram of the utility model ultralong-stroke supersound projector magnetic conduction T iron.
Shown in the utility model figure: 1 substrate, 2 cylinders, 2.1 central through holes, 2.2 arc transition connecting walls, 3 annular recess.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, ultralong-stroke supersound projector magnetic conduction T iron of the present utility model, comprise substrate 1 and cylinder 2, unlike the prior art, described substrate 1 and cylinder 2 are integral type structure, described integral structure is for forging into shaped piece, and the magnetic conduction T iron after forging forming can ensure the perpendicularity of cylinder, makes the error of perpendicularity of cylinder within allowed band.
For convenience of forging forming, the position that described substrate 1 is connected with cylinder 2 is provided with annular recess 3, and described annular recess 3 is positioned at the upper surface of substrate 1.
The upper surface of described substrate 1 is horizontally disposed with, and the lower surface of described substrate 1 tilts and the thickness of substrate 1 is thinning gradually to edge by center.
The central through hole 2.1 of described cylinder 2 is conical through-hole wide at the top and narrow at the bottom.
Lateral wall and the top end face intersection of described cylinder 2 are provided with arc transition connecting wall 2.2, and forging forming is convenient in the setting of arc transition connecting wall, and avoid the blocked up phenomenon generation of top thickness, and arc transition connecting wall entirety is mellow and full, regular.
After forging forming is crossed by ultralong-stroke supersound projector magnetic conduction T Tie Tong of the present utility model, can effectively overcome the deficiency causing the error of perpendicularity large because height of column is high, the setting of annular recess 3, arc transition connecting wall 2.2 simultaneously, the phenomenon that can effectively avoid part blocked up occurs, and makes that forging forming is smooth and easy to carry out.
Claims (3)
