Abstract
The invention discloses the preparation method of a kind of speaker sound-absorbing material；It comprises the steps of: one, take the raw material of following weight portion: cotton fiber 15% 20%, polyester fiber 40% 45%, aluminum fiber 10% 15%, Gypsum Fibrosum powder 10% 15%, nano-sized carbon 5% 10%, aluminium hydroxide 1% 2%, polyisobutylene 2% 4%；Two, above-mentioned raw materials is made slurry and mixes；Three, being slab structure by mixed slurry hot pressing, the upper surface of slab structure is waveform；Four, in slab structure, spray acrylic acid polyester waterproofing agent, and dry；Five, slab structure being punched out, die-cut size is 15% the 30% of speaker back cavity size；The sound-absorbing material sound-absorbing effect of gained is good, the F0 of speaker module can be made to drop to of a sufficiently low, waterproof, good flame retardation effect, low cost.
Description
Technical field
The present invention relates to quieter material technical field, be specifically related to the preparation method of a kind of speaker sound-absorbing material.
Background technology
Speaker module converts electrical signals to acoustical signal energy transducer as one, be in electro-acoustic product can not or
The parts lacked.Speaker module is generally made up of shell and loudspeaker monomer, and whole module shell inner chamber is divided by loudspeaker monomer
It is divided into the front operatic tunes and two cavitys of the rear operatic tunes.In order to improve speaker module acoustical behavior (as reduce module resonant frequency F0,
Spread bandwidth), it will usually setting up sound-absorbing part in the rear operatic tunes, sound-absorbing part can sponge part acoustic energy, is equivalent to expand rear chamber
Volume, thus reduce module F0 effect.Traditional sound-absorbing part is foaming kind foam, such as polyurethane, tripolycyanamide etc..Closely
Year, the most lightening along with Wearable electronic product, operatic tunes volume is constantly compressed thereafter, traditional foaming kind foam sound-absorbing
It is of a sufficiently low that part is difficult to make the F0 of speaker module drop to, it is impossible to ensures the medium and low frequency tonequality of speaker module.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that the system of a kind of speaker sound-absorbing material
Preparation Method.
For achieving the above object, the technical solution used in the present invention is: it comprises the steps of:
One, the raw material of following weight portion is taken: cotton fiber 15%-20%, polyester fiber 40%-45%, aluminum fiber 10%-15%, Gypsum Fibrosum powder
10%-15%, nano-sized carbon 5%-10%, aluminium hydroxide 1%-2%, polyisobutylene 2%-4%；
Two, above-mentioned raw materials is made slurry and mixes；
Three, being slab structure by mixed slurry hot pressing, the upper surface of slab structure is waveform；
Four, in slab structure, spray acrylic acid polyester waterproofing agent, and dry；
Five, slab structure being punched out, die-cut size is the 15%-30% of speaker back cavity size.
After using such scheme, present invention have the beneficial effect that the system of a kind of speaker sound-absorbing material of the present invention
Preparation Method, simple to operate, the sound-absorbing material sound-absorbing effect of gained is good, the F0 of speaker module can be made to drop to of a sufficiently low, waterproof, resistance
Fire effective, low cost.
Detailed description of the invention
The present invention is further illustrated below.
This detailed description of the invention the technical scheme is that it comprises the steps of:
One, the raw material of following weight portion is taken: cotton fiber 15%-20%, polyester fiber 40%-45%, aluminum fiber 10%-15%, Gypsum Fibrosum powder
10%-15%, nano-sized carbon 5%-10%, aluminium hydroxide 1%-2%, polyisobutylene 2%-4%；
Two, above-mentioned raw materials is made slurry and mixes；
Three, being slab structure by mixed slurry hot pressing, the upper surface of slab structure is waveform；
Four, in slab structure, spray acrylic acid polyester waterproofing agent, and dry；
Five, slab structure being punched out, die-cut size is the 15%-30% of speaker back cavity size.
After using such scheme, present invention have the beneficial effect that the system of a kind of speaker sound-absorbing material of the present invention
Preparation Method, simple to operate, the sound-absorbing material sound-absorbing effect of gained is good, the F0 of speaker module can be made to drop to of a sufficiently low, waterproof, resistance
Fire effective, low cost.
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.
