Description
Technical field
The utility model belongs to sound film manufacturing technology field more particularly to a kind of high taper of ultrathin type spends more muscle sound film.
Background technology
The generally tapered structure of its structure of sound film.
However, existing sound film when taper is molded, is influenced by material and stretching stress, leads to existing sound film
Cone height is relatively low, meanwhile, the total intensity of product is poor.
For example, Chinese patent discloses a kind of throat cover integrated loud-speaker, application number 91204999.5, by taper
The compositions such as pipe, sound film, magnetic circuit system, round operculum laryngis, hollow throat taps, big horn, reflection tube, it is by round operculum laryngis and three stents
Design is integral, and taper inner tube one end is dexterously taper fit, and be bonded and to form one with the tubulose platform inner circle of round operculum laryngis,
Be bonded on the recess of round operculum laryngis using three supports of hollow throat taps, solve conventional loudspeakers safety it is poor, production week
The defects of phase is long, waste metal material, and from 12 kinds of parts, 35 procedures be reduced to 8 kinds of parts, 14 procedures can just assemble and
Into high pitch loudspeaker.
Although above-mentioned scheme has many advantages, such as above, above-mentioned scheme its do not solve thoroughly it is above-mentioned
Technical problem.
Utility model content
The purpose of this utility model is in view of the above-mentioned problems, providing one kind enhancing structure intensity and can expand taper
The high taper of ultrathin type for stretching height spends more muscle sound film.
In order to achieve the above objectives, the utility model employs following technical proposal：The high taper of this ultrathin type spends more muscle sound film
Including inner taper, the small head end of inner taper has closure, shirt rim portion is connected on the outside of inner taper stub end, in shirt rim
Portion and the junction of inner taper are equipped with to the first annular protrusion far from inner taper side protrusion, are equipped at the middle part in shirt rim portion
Protrusion direction second annular protrusion opposite with the first annular raised protrusion direction, is additionally provided with several positions in the portion of shirt rim
It is described between first annular protrusion and the second annular protrusion and protrusion direction and the consistent strip bulge of first annular protrusion
Strip bulge even circumferential is distributed.
By designing first annular protrusion, the second annular protrusion and strip bulge, can with enhancing structure intensity, meanwhile,
Taper drawing height can also further be expanded, design is more reasonable.
In the above-mentioned high taper of ultrathin type spends more muscle sound film, the junction of the shirt rim portion and inner taper be equipped with
The first annular corresponding first annular groove of protrusion.
The design of the structure easy to process can manufacture.
In the above-mentioned high taper of ultrathin type spends more muscle sound film, it is equipped in the middle part of the shirt rim portion and second annular
The corresponding second annular groove of protrusion.
The design of the structure easy to process can manufacture.
In the above-mentioned high taper of ultrathin type spends more muscle sound film, the shirt rim portion is equipped with several convex with described bar shaped
Play one-to-one strip groove.
The design of the structure easy to process can manufacture.
In the above-mentioned high taper of ultrathin type spends more muscle sound film, the groove width of the first annular groove is less than the second annular
The groove width of groove.
In the above-mentioned high taper of ultrathin type spends more muscle sound film, the inner taper outer wall has arc-shaped concave, inside
The inner wall of tapered portion has and the corresponding arc convex of arc-shaped concave.
Compared with prior art, the high taper of this ultrathin type is spent more the advantages of muscle sound film and is：
It 1st, can be with enhancing structure intensity, together by designing first annular protrusion, the second annular protrusion and strip bulge
When, it can also further expand taper drawing height, design is more reasonable.
2nd, it is simple in structure and easily fabricated.
Description of the drawings
Fig. 1 is structure diagram provided by the utility model.
Fig. 2 is schematic cross-sectional view provided by the utility model.
Fig. 3 is enlarged structure schematic diagram at A in Fig. 2.
In figure, inner taper 1, first annular raised 11, first annular groove 12, closure 2, the 3, second annular of shirt rim portion
