Abstract
A method of earphone biology vibrating diaphragm is prepared using fish glue, belong to earphone diaphragm technical field, existing earphone diaphragm can be solved easily to be distorted, sound resolution detail difference and the earphone diaphragm type of biomaterial are limited, the higher problem of price, this method passes through glue, pounds glue, takes five glue juice, concentration, film forming steps, preparation method simple process and low cost of the invention.
Description
Technical field
The invention belongs to earphone diaphragm technical fields, and in particular to and it is a kind of to utilize natural biologic material-fish glue, prepare ear
The method of machine biology vibrating diaphragm.
Background technique
Vibrating diaphragm is loudspeaker crux accessory, its quality and consistency directly influence the technical indicator and finished product of loudspeaker
Rate.The main function of vibrating diaphragm is vibration, and one for influencing vibration dynamic performance is elasticity, the other is inertia.The vibration of rigidity foot
Film, elastic behavior is linear, and vibration Dynamic comparison is good, and audio presentation balance reasonably can restore and play back voice signal；And
Light-weight vibrating diaphragm, motional inertia is smaller, and clarity and the detail section performance of sound are preferable.Therefore, diaphragm materials are usual
Select a kind of density small, rigidity is good, damps moderate material.Diaphragm materials currently on the market have natural fiber material, as paper,
Silk etc., metal vibration diaphragm, Polymer Synthesizing fiber vibrating diaphragm, such as polyamide, polyurethane, liquid crystal polymer, and biological vibrating diaphragm etc..No
Vibrating diaphragm with material respectively has feature, is bright spot as macromolecule vibrating diaphragm is at low cost, but poor rigidity, internal resistance are small, are easy distortion；Paper vibration
Film is easy driving, high to the reduction degree of sound, sound compare naturally, still audio be affected by the external environment it is bigger；Metal vibration
Membrane rigidity is outstanding, clear, and tone color is accurate, and the details of especially high frequency is very rich, still, gold for opposite other materials
Category weight is larger, and the driving for unit is not to be easy to.Biomaterial vibrating diaphragm usually light-weight, good toughness, the wink of earphone
State dynamically does very well, and sound is naturally soft very resistance to be listened.But presently commercially available biological vibrating diaphragm type is limited, price is higher, opens
It sends out novel and various biological vibrating diaphragm, more diverse seeing and hearing enjoyment can be brought.
The use of fish glue bonds wood, furniture using the high viscosity of fish glue in existing thousand history of China, ancients,
Between one fourth of the twelve Earthly Branches of a tenon, the wisdom of ancient Chinese has been agglomerated.The manufacture craft of fish glue is known, however its film-forming quality
Unutilized always, air bladder adhesiveness is very high, and adhesive strength is more than general animal glue, and therefore, film strength is high after film forming, elasticity
And good toughness.Since its main component is that collagen, gelatin, glutinous polysaccharide and multivitamin and calcium, zinc, iron, selenium etc. are a variety of
Microelement, ingredient close to human body ear-drum ingredient, to the reduction of sound closer to human body ear-drum.Therefore, for doing earphone vibration
Film will be good selection.
Summary of the invention
The present invention is easily distorted for existing earphone diaphragm, the earphone diaphragm kind of sound resolution detail difference and biomaterial
Class is limited, and the higher problem of price provides a kind of method for preparing earphone biology vibrating diaphragm using fish glue.
The present invention adopts the following technical scheme:
A method of earphone biology vibrating diaphragm being prepared using fish glue, is included the following steps:
The first step, glue, after the air bladder after drying is impregnated 15-24h into the water, being crushed to partial size is 0.5cm hereinafter, by powder
Air bladder after broken is added to the water, and under the conditions of 100 DEG C, 40-60min is boiled in heating；
Second step pounds glue, and the air bladder after heating in the first step is boiled, which is ground to, becomes thick liquid；
Third step takes glue juice, and the thick liquid that second step obtains is squeezed out glue juice by gauze；
20-40min, the glue after being concentrated is added under the conditions of 100 DEG C in 4th step, concentration, the glue juice that third step is obtained
Juice；
Glue juice after the concentration of 4th step is injected mold by the 5th step, film forming, after dry, i.e., earphone biology vibrating diaphragm.
In the first step, the mass ratio of the smashed air bladder and water is 1:100-150.
In third step, the aperture of the gauze is 100 mesh.
In 5th step, the drying temperature is 55 DEG C or 25 DEG C.
Beneficial effects of the present invention are as follows:
1. the earphone biology vibrating diaphragm ingredient and human body ear-drum that are prepared using preparation method of the invention are close, have and ear-drum phase
Close sound-reducing characteristic.
2., density 0.38g/cm light using earphone biology diaphragm mass prepared by preparation method of the invention3, Young
Modulus is 2.5GPa, and sound is naturally soft.
3. preparation method simple process and low cost of the invention.
Detailed description of the invention
Fig. 1 is the frequency response curve of background white noise.
Fig. 2 is the frequency response curve of biological vibrating diaphragm of the invention.
Specific embodiment
Embodiment
Fish glue of the 5g after dry is put into clear water and impregnates for 24 hours, after impregnating and feeling like jelly, with crushing by the first step, glue
Machine is crushed to 0.5cm hereinafter, the water of 500ml is added, and 1h is boiled in heating, during heating, according to circumstances adds water to keep water successively
Air bladder is just flooded, it is glutinous soft to air bladder fragment, after gluing, stop heating；
Second step pounds glue, and the air bladder after above-mentioned softening is taken out together with water, is put into mortar, grinding is smashed to pieces to fragment to be become completely
At viscous pastes；
Third step takes glue juice, thick liquid will be obtained in second step, is bound up with gauze with 100 mesh, and glue juice is squeezed out；
4th step, concentration continue to heat 20min by glue juice under the conditions of 100 DEG C, are concentrated into glue juice in thick；
Glue juice injection diameter after concentration is while hot in the vibrating diaphragm mold of 9.5mm by the 5th step, film forming, and glue juice comes into full contact with mould
Wall, extra glue juice are poured out, and are put into baking oven (temperature control at 55 DEG C or less) or are dried at room temperature for, the film after drying from
It takes out, is measured with a thickness of 0.2mm, diameter 9.5mm in mold.
Molding vibrating diaphragm is installed in In-Ear Headphones, test frequency response curve, compare background white noise frequency response curve and
The frequency response curve of this biology vibrating diaphragm, this vibrating diaphragm can preferably restore high, normal, basic each section audio, be distorted smaller.
The physical parameter of earphone biology vibrating diaphragm and existing earphone diaphragm of the invention compares, such as table 1.
The physical parameter of the earphone biology vibrating diaphragm of the invention of table 1 and existing earphone diaphragm compares
