Abstract
The invention discloses a preparation method of loudspeaker diaphragms, and relates to the technical field of a loudspeaker. The preparation method comprises the steps of mixing high-molecular polymer as substrate with solution, wherein the mixing time is 30-40 minutes; heating the mixed solution while mixing is carried out; adding graphene high-molecular polymer mixed material film after the mixing is carried out; cutting the film into film bodies with corresponding sizes through laser; and blanking the film bodies to prepare the loudspeaker diaphragms. According to the method, the quality of the products is improved; the usage is convenient; the preparation method is simple and convenient; and the time is reduced.
Description
Technical field
The present invention relates to loudspeaker techniques field, be specifically related to the preparation method of a kind of speaker vibrating diaphragm.
Background technology
Speaker is the energy transducer that a kind of the signal of telecommunication is changed into acoustical signal, the good and bad shadow to tonequality of the performance of speaker
Ring the biggest.Speaker is a device the weakest in stereo set, and for acoustics, it be again one the heaviest
The parts wanted.Speaker of a great variety, and price differs greatly.Audio frequency electric energy passes through electromagnetism, piezoelectricity or electrostatic effect, makes
Its cone or diaphragm vibration the air with surrounding produce resonance (sympathetic response) and send sound.
Low-grade plastic loudspeaker box, because its casing is thin, cannot overcome resonance, can say (also have the plastics that part designs without tonequality
Audio amplifier will be far better than wooden acoustic box inferior)；Wood cabinet reduces the sound dye that casing resonance is caused, and tonequality is generally better than
Plastic loudspeaker box.
Generally multimedia loudspeaker box is all double unit two divided-frequency designs, and a less speaker is responsible for alt output,
And another bigger speaker is responsible for the output of middle bass.
Select audio amplifier and be considered as the material of the two loudspeaker: the voice unit of active multimedia loudspeaker boxes is existing based on soft top dome
(the titanium film top dome etc. in addition with for simulating source of sound), it matches with digital tone source and can reduce the stiff sense of high-frequency signal,
Give gentle, smooth, fine and smooth sensation.Multimedia loudspeaker box is existing with soft balls such as the preferable cortina of quality and lower-cost PV films
That pushes up is in the majority.
Its mixing in the preparation of the existing diaphragm of loudspeaker is uneven, and loses time, inefficiency.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that the preparation side of a kind of speaker vibrating diaphragm
Method.
In order to solve the problem existing for background technology, the preparation method of a kind of speaker vibrating diaphragm of the present invention, it
Preparation method is: mixed as base material with solution by high molecular polymer, incorporation time 30-40 minute, adds hot mixing during mixing
Solution, adds Graphene high molecular polymer mixing material film, by being laser-cut into corresponding size after having mixed
Film body, carries out stamping-out on film body and makes the diaphragm of loudspeaker.
Present invention have the beneficial effect that the quality that improve product, easy to use, preparation method is easy, time-consuming.
Detailed description of the invention
This detailed description of the invention adopts the following technical scheme that its preparation method is: using high molecular polymer as base material
Mix with solution, incorporation time 30-40 minute, during mixing, heat mixed solution, after having mixed, add Graphene polyphosphazene polymer
Compound mixing material film, by being laser-cut into the film body of corresponding size, carries out stamping-out on film body and makes speaker and shake
Film.
The above, only in order to technical scheme to be described and unrestricted, those of ordinary skill in the art are to this
Other amendment or equivalent that bright technical scheme is made, without departing from the spirit and scope of technical solution of the present invention,
All should contain in the middle of scope of the presently claimed invention.
