As a further improvement, a circle is molded at the interior lateral margin of the outstanding edge outer surface
The installation groove of annular；The outer peripheral edge of the vibrating diaphragm is fixed in installation groove, the circle of vibrating diaphragm
The heart and the center of circle for installing groove are concentric.
To achieve these goals, the present invention provides a kind of preparation method of sound film of trumpet, bag
Include step 1, go out shaking for a circle using acrylonitrile-butadiene-styrene copolymer plastic shaping
Film；Step 2, by the circular membrane electroplating surface last layer Nanometer material；Step 3, general
The circular membrane is positioned in a mould, using room temperature vulcanized silicone rubber in the mould in shaking
Molded on the outer peripheral edge of film at a circular outstanding edge, the interior lateral margin for hanging edge outer surface
The installation groove of an annular is molded, installation groove is fixed in the outer peripheral edge of the vibrating diaphragm
Interior, its center of circle and the center of circle for installing groove are concentric.
As described above, sound film of trumpet of the present invention and preparation method thereof by vibrating diaphragm by acrylonitrile-
BS plastics are made, and in one layer of nm material of electroplating surface of vibrating diaphragm
Material, then makes outstanding edge take shape on vibrating diaphragm outer peripheral edge using room temperature vulcanized silicone rubber, so that
It can ensure that vibrating diaphragm and outstanding edge are concentric, it is to avoid the distortion level of increase loudspeaker, in addition, using this
Loudspeaker of the high-frequency effect of the loudspeaker of invention sound film of trumpet than the sound film of trumpet using paper material
More preferably, so as to improve the quality of loudspeaker.

Embodiment
To describe technology contents, construction feature, the purpose realized and the work(of the present invention in detail
Effect, below in conjunction with specific embodiment and coordinates accompanying drawing to be described in detail.
Fig. 1 and Fig. 2 are referred to, a kind of sound film of trumpet 100 is installed in a loudspeaker (not shown)
On, including a vibrating diaphragm 10 and an outstanding edge 20.
Referring to Fig. 3, the rounded shape of the vibrating diaphragm 10, by acrylonitrile-butadiene-styrene (ABS)
Copolymer (Acrylonitrile Butadiene Styrene, ABS) plastics are made, surface electricity
It is coated with one layer of Nanometer material.
The outstanding edge 20 is in annular shape, by room temperature vulcanized silicone rubber (Room
Temperature Vulcanized Silicone Rubber, RTV) it is in-molded in vibrating diaphragm 10
Outer peripheral edge on, the installation of an annular is molded at the interior lateral margin of the outstanding outer surface of edge 20
Groove 21.The outer peripheral edge of the vibrating diaphragm 10 is fixed in installation groove 21, vibrating diaphragm 10
The center of circle and the center of circle for installing groove 21 are concentric.
The preparation method of sound film of trumpet 100 of the present invention, comprises the following steps：
Step 1：Go out one using acrylonitrile-butadiene-styrene copolymer plastic shaping circular
Vibrating diaphragm 10；
Step 2：By the electroplating surface last layer Nanometer material of circular membrane 10；
Step 3：The circular membrane 10 is positioned in a mould (not shown), room is used
Temperature vulcanizable silicone rubber is circular in molding one on the outer peripheral edge of vibrating diaphragm 10 in the mould
The installation of an annular is molded at outstanding edge 20, the interior lateral margin of the outstanding outer surface of edge 20
Groove 21, thus the outer peripheral edge of the vibrating diaphragm 10, which is directly fixed on, installs in groove 21.Shake
The center of circle of film 10 and the center of circle for installing groove 21 are concentric.
Referring to Fig. 4, the figure shows using sound film of trumpet 100 of the present invention loudspeaker with it is existing
Use paper material sound film of trumpet (not shown) loudspeaker frequency response curve,
Wherein curve I is the frequency response curve of the loudspeaker of the sound film of trumpet using paper material, bent
Line II is the frequency response curve of the loudspeaker using sound film of trumpet 100 of the present invention.By both
Frequency response curve contrast, using the loudspeaker of sound film of trumpet 100 of the present invention in low-frequency range
Frequency response curve and the actual loudspeaker for listening to the upper sound film of trumpet with using paper material are simultaneously
Without too big difference, and in loudspeaker relative usage of the high band using sound film of trumpet 100 of the present invention
The acoustic pressure of the loudspeaker of the sound film of trumpet of paper material is improved 5dB effect, improves high frequency
Definition, the high-frequency effect using the loudspeaker of sound film of trumpet 100 of the present invention is more preferable.
Referring to Fig. 5, the figure shows using sound film of trumpet 100 of the present invention loudspeaker with it is existing
Use paper material sound film of trumpet loudspeaker rate of total harmonics curve map, wherein
