Description

Environment-friendly speaker diaphragm Hanji paper body and its manufacturing method {Friendly environment speaker diaphragm korean paper body and the manufacturing method}

The present invention relates to a speaker diaphragm Hanji paper body with an eco-friendly ocher, biotite added, and a method for manufacturing the same. More specifically, it promotes blood circulation and metabolism by far infrared rays emitted from ocher and biotite, as well as blocking harmful electromagnetic waves. Promote health by purifying, deodorizing and deodorizing harmful substances such as antibacterial action, polluted indoor air purification, formalin, etc., waterproofing tensile strength, flexural strength, heat distortion temperature And high gas proof and ocher and biotite bonds enable high quality sound quality due to wideband, high efficiency and constant sound output. will be.

In general, a speaker is an acoustic device that converts an electrical signal into vibration of a diaphragm to generate a small wave in the air to radiate sound waves, also called a speaker or a loudspeaker.

The loudspeaker is a type that the diaphragm is placed directly in the air is called a radiant speaker, and the type where the diaphragm is placed in the horn is called a horn type speaker, and the direct radiant type is usually used in a speaker such as an audio, automobile, ship, airplane, etc. Most cone speakers are used, and some use metal vibration plates.

The cone speaker uses a lot of conical plates in the diaphragm, and a coin type is used more than an electromagnetic type magnetic speaker (magnetic loudspeaker).

Since the efficiency is proportional to the square of the total number of magnets passing through the coil, a large diameter using a large magnet has a good electroacoustic conversion efficiency.

A sound pressure of 105 dB (1.5% efficiency) to 90 dB (0.3%) is generated at 1m on-axis for an electrical input of 1VA.

In addition, the efficiency is lower than the horn speaker's efficiency of 30 to 40%, but it is inexpensive and compact, and it is a trumpet speaker that can be seen outdoors such as a station or a playground, and has good electrical and acoustic characteristics. It doesn't need a sound box to accommodate the speakers, so it is used for the speakers of medium size and below.

Therefore, the speaker has a coin type, an electromagnetic type, an electrostatic type, a dielectric type, and a magnetostriction type according to the principle and method of converting an electric signal into sound waves. Etc., coin type (dynamic type) with good performance is widely used for music reproduction and voice.

Coin type emits signal energy by using the principle that mechanical force acts on the coil and causes movement according to the strength of the current when the voice signal current flows to the coil (boy coil) in the magnetic field of the permanent magnet.

Signal energy refers to energy having a special form corresponding to a signal in the audible region (20 to 20,000 ㎐) frequency, including music and music.

Speakers must preserve the essential characteristics of signal energy in the form of sound. Therefore, acoustic signal energy, such as buzzer, gong, siren, etc., is not the same as the electrical signal in form.

The part of the speaker that converts electrical energy into mechanical energy is usually called a motor or voice coil.

When the voice coil vibrates the diaphragm, the air in direct contact with the vibrator vibrates to generate sound waves corresponding to the form of the original speech or sound signal.

Often voice coils consist of wire coils moving in a strong magnetic field, but sometimes the diaphragm is actuated by the action of electrostatic or piezoelectric materials.

The diaphragm body (BODY) applied to the speaker as described above may be made of various materials such as synthetic resin, polypropylene, kevlar, carbon, polymer laminate, aluminum, rubber, metal, paper, or according to the shape or type of the speaker. It may be produced by mixing.

However, such a conventional paper body (PAPER BODY) is a long-term operation, fatigue accumulates, the sound output is not constant or deteriorated, and when exposed to high or low temperatures, the sound quality of the speaker is degraded, the ear, such as earphones When used in direct contact, the speaker is exposed to electromagnetic waves and positive ions as it is, causing a problem that adversely affects the human body.

In addition, the conventional diaphragm paper body should be thin and have good strength and elasticity. However, only the pulp is made of pulp, so paper is crumbly, weak, and the electric signal is converted into a physical signal to cause a lot of vibration. ) Itself has been deformed.

1 is a flow chart for explaining the method according to the invention.

Recently, various environmental pollutants are contaminated around the living area, and the number of patients due to diseases caused by pollution such as polluted harmful substances and formalin in closed spaces such as automobiles is increasing rapidly. It is spreading.

On the other hand, the excellent performance of ocher and biotite has been found, and various products using ocher and biotite have been widely used.

The ocher is described as follows.

1) Excellent antibacterial performance

The microorganisms in ocher prevent the growth of various bacteria and mites, suppress the mold and detoxify toxic gas.

2) Excellent air purifying and deodorizing performance

Powerful deodorizing power removes odors in the room and removes contaminants, keeping fresh air.

On the other hand, loess (黃土) is literally yellowish soil.

However, academically, the term ocher (黄土) refers to a yellow mineral (Loes) composed mainly of silt (Silt 0.002 ~ 0.005mm), which was originally carried by wind.

Ocher is a honeycomb structure with a large surface, and a large number of spaces have a multi-layer structure.

In this sponge-like hole, far-infrared rays are absorbed and stored in a large amount, radiating when heated to stimulate molecular activity of other objects.

In other words, ocher absorbs solar energy for many years and can be called a solar energy reservoir as a silicon mineral.

Far-infrared radiation emitted from ocher activates cell physiology (recovery of fatigue, anti-aging), generates heat energy, discharges harmful substances and improves metabolism.

On the other hand, the components of ocher are shown in Table 1.

Ocher composition scheme division Calcium oxide Silicon oxide Potassium oxide Magnesium oxide Iron oxide Ocher 10 30 3 0.3 4 Component Scheme Units are% and remainder Organic

On the other hand, it will be described as far infrared rays emitted from the yellow soil.

Far infrared rays, which have the most beneficial wavelengths (5.7 to 10 microns) among the infrared rays, penetrate deep into the skin (3-4 cm deep) and promote cells to increase body temperature.

At this time, as the body temperature rises, there is a remarkable effect on growth promotion.

In particular, due to the excellent effect obtained by releasing a large amount of sweat, various toxic substances, waste products, heavy metals are released in a large amount with sweat, constitution is improved to a healthy alkalinity.

In addition, because it relaxes the physical and mental tension is also effective in relieving stress caused by adult diseases.

The effects of far infrared rays on living organisms have been reported for warming effect, blood promotion, metabolic function enhancement, sweating promotion, analgesic effect and some other biological activities. Infrared light is more efficient and more efficient than visible light in F.W.Hershel in 1800. Since it was first discovered in 1835, A. Amper named the existence of electromagnetic waves with long wavelengths rather than the red color of visible light.

Among these infrared electromagnetic waves, light having a property of reflection with a boundary of 4 microns is called near infrared, and radiation having an absorption property is called far infrared.

The effects of far infrared rays on the human body are as follows.

Far infrared rays are heat energy penetrating up to 40mm in the human body as a strong heat rays.

When far-infrared radiation is emitted from the soil, bacteria that cause various diseases in the human body are weakened due to its thermal action, and the capillaries in the human body are expanded to promote blood circulation as well as to promote the generation of cellular tissues.

Far infrared rays emitted from ocher are the best radiant heat for human body.

As mentioned above, ocher is harmful to the human body.

1. Breathe (air is well ventilated)

2. Excellent humidity control ability.

3. Great antibacterial effect.

4. Mold does not bloom.

5. Excellent odor removal effect.

6. Good heat dissipation effect.

7. Long lasting high temperature.

8. Far infrared radiation is high.

The biotite is described as follows.

Biotite is a life stone that has a far infrared ray emissivity (94%) that is about three times higher than ocher and elvan, and has a germanium content of 36 ppm, and has been recognized as a mysterious mineral since it has been effective enough to call biotite stone a weak stone. Brown-black, green-black, etc. The split side has pearl luster and sometimes metal luster.

As a result of human experiments, it is an environmentally friendly substance that is excellent in blood circulation, chronic bronchitis, etc. by active metabolism in the body.

On the other hand, the components of biotite are shown in Table 2.

As described above with reference to the accompanying drawings, the diaphragm Hanji paper body for a speaker containing a loess and biotite harmful to the human body and a manufacturing method thereof, will be described in detail as follows.

First, cut 24 ~ 52% by weight of mulberry (Korean support fee) to a certain size (for example, 5 ~ 10mm) in the fiber direction, and is called for 2 hours in lukewarm water at 30 ~ 50 ℃.

Here, the paper mulberry is used as a raw material for making the paper, such as the stem is a lot of fiber.

Then, 6 to 16% by weight of pulp (UKP, BKP, BSP, USP, MANILA, ABACK) is called in water at 10 to 20 ° C. for at least 3 hours.

Here, the pulp (pulp) is a raw material for making paper and the like as a raw material cellulose extracted by chemical treatment of components extracted from fiber plants such as wood.

In this way, the first step (S1) to prepare the material to be mixed through the bottom of each of the mulberry and pulp is configured.

After preparing the material to be mixed in the first step (S1), put water, mulberry, and pulp at room temperature (about: 10 to 20 ° C.) in a beater, and dissociate the pulp mixture (decompose the compound into simple components). Perform a second step (S2) to perform.

 And in the third step (S3) after the dissociation operation by lowering the upper biting blade to be adjacent to the lower biting blade of the beater to maintain the high pulp (FN) of the pulp mixture 350 ~ 800 CC through the mixer action of the biting blade Perform beating work (grinding of paper particles).

At this time, the beating blade lowers the upper beating blade so that the gap between the lower beating blade and the upper beating blade is maintained at 2 to 3 mm, thereby beating the mixture through the intermixing action to finely crush the particles.

Here, the pulp is thinner than the paper mulberry, high productivity, and can produce paper at a low price, the strength of the fiber is weak, there is a disadvantage in poor storage.

Therefore, by mixing the mulberry and pulp to compensate for the shortcomings, the elastic modulus is high, and the thin but excellent strength, it is possible to produce paper with high productivity and preservation.

After performing the beating operation, the color of the mixture after the beating may be produced by the ocher only color, and may be mixed by adding a dye (Direct Dyes), and the color of the dye is generally black. It is used a lot, but various colors can be changed to fit the concept of the finished speaker.

In the fourth step (S4), 12 to 18% by weight of ocher processed into powder of 100 to 1,000 mesh and 6 to 8% by weight of biotite and 6 to 10% by weight of fixer which are processed into powder of 200 to 800 mesh are stored at room temperature. Mix and dilute to 2,000cc, and mix into the pulp mixture where the beating work is completed.

Here, the fixing agent is for preventing the color from fading or decomposition degradation of the material by absorbing ultraviolet rays from sunlight or electric light.

In the fifth step (S5), 12 to 16% by weight of rosin (rosin sizing agent) is diluted in 2000 cc of water at 60 to 80 ℃ and then added to the pulp mixture and mixed.

In the sixth step (S6) 6 to 8% by weight of alumina sulfate is diluted in 2,000cc of water at 15 to 40 ℃ and added to the pulp mixture and mixed.

The alumina sulfate is mainly used for sterilization, disinfection and odor removal as a chlorine disinfectant, and adjusts P.H of the mixture.

At this time, it is preferable that the pH index measured in the mixture of alumina sulfate is maintained in the range of 4 to 5.5.

In the seventh step (S7), the mixture of alumina sulfate is naturally dehydrated to a water content of 10 to 30%, and then Hanji paper raw material is produced.

When producing the paper raw material, the pulp mixture is put into the papermaking tank of the cone paper automatic paper machine and then stirred by the air pressure blown by the broa, and the blowing pressure of the broa is the papermaking tank at the pressure of 6 ~ 7 kg / ㎠ At the bottom, it is to prevent the hanji paper raw material from sinking and at the same time to stir constantly.

In the eighth step S8, the paper raw material is pressed by a hot press molding machine to complete the Hanji paper body.

At this time, the hot press molding machine is a typical hot press molding machine of the upper mold of 190 ~ 210 ℃, and the lower mold of 170 ~ 190 ℃.

It provides an eco-friendly far-infrared emitting speaker Hanji diaphragm paper body, characterized in that it comprises a step configured as described above.
