Description
본 발명은 스피커용 진동판에 관한 것으로, 특히 스피커의 내부손실을 향상시키기 위해 내부 표면을 코팅한 스피커용 진동판에 관한 것이다.The present invention relates to a diaphragm for a speaker, and more particularly, to a diaphragm for a speaker coated with an inner surface to improve the internal loss of the speaker.
일반적으로 음성의 9확대 재생을 목적으로 하는 스피커의 코일을 통해 입력되는 전기적 힘이 자석에 의한 자계 내에서 기계적인 진동으로 변환되어 음향을 발생시키기 때문에 떨림이 발생되는 진동판의 형상 및 재질은 음의 성질을 결정하는 요인으로서 중요하다.In general, since the electric force input through the coil of the speaker for the purpose of 9 enlarged reproduction of the voice is converted into mechanical vibration in the magnetic field by the magnet to generate the sound, the shape and the material of the vibration plate generating the tremor are negative. It is important as a factor in determining the nature.
종래 기술에 의한 스피커용 진동판은 주로 종이나 폴리 프로필렌(poly propylene)을 사용하여 제조하였으며, 물성을 향상시키기 위해 무기질 또는 고탄성의 물질을 충진재(filler)로 하는 도료를 코팅하여 사용하였다.The diaphragm for the speaker according to the prior art is mainly manufactured using paper or poly propylene (poly propylene), was used by coating a coating material (filler) with inorganic or high elastic material to improve the physical properties.
그러나, 상기와 같이 사용되는 종래의 고탄성의 재료에 의한 스피커용 진동판은, 음질을 날카롭고 딱딱하게 만들기 때문에 청취자로 하여금 장시간 사용시 피로감을 느끼게 하는 문제점이 있었으며, 쉬게 흠집이 발생하여 외관을 나쁘게 만드는 문제점이 있었다.However, the diaphragm for a speaker made of a conventional high-elastic material used as described above has a problem that the listener feels fatigue when used for a long time because the sound quality is sharp and hard, and the scratches occur easily and the appearance is bad. There was this.
이에, 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 그 목적으로 하는 바는 음질이 부드럽고, 외관이 미려하며, 긁힘이 방지되는 스피커용 진동판을 제공함에 있다.Accordingly, the present invention has been made to solve the above problems, and an object thereof is to provide a diaphragm for a speaker that is soft in sound quality, beautiful in appearance, and prevents scratches.
제1도는 본 발명에 의한 스피커용 진동판의 구성을 나타내는 일부 단면도.1 is a partial cross-sectional view showing the configuration of a diaphragm for a speaker according to the present invention.

상기 목적을 달성하기 위한 본 발명에 따른 스피커용 진동판은, 종이를 재질로 하여 제조된 스피커용 진동판에 있어서, 내부 표면이 콜라겐을 함유한 합성수지계도료로 코팅된 것을 특징으로 한다.Speaker diaphragm according to the present invention for achieving the above object, in the speaker diaphragm made of a material, characterized in that the inner surface is coated with a synthetic resin paint containing collagen.
[실시예]EXAMPLE
이하, 본 발명에 따른 스피커용 진동판을 제1도를 참조하여 설명하면 다음과 같다.Hereinafter, the diaphragm for a speaker according to the present invention will be described with reference to FIG. 1.
제1도는 본 발명에 의한 스피커용 진동판의 구성을 나타내는 일부 단면도이다.1 is a partial cross-sectional view showing the configuration of a diaphragm for a speaker according to the present invention.
본 발명에 따른 스피커용 진동판은 제1도에 도시된 바와 같이, 종이진동판(1)과, 상기 종이진동판(1)의 내측면에 코팅된 합성수지계도료(2)로 이루어지며, 상기 합성수지계도료(2)는 내부에 콜라겐입자(3)가 균일한 분포로 함유된다.The diaphragm for the speaker according to the present invention, as shown in FIG. 1, is made of a paper vibration plate 1 and a synthetic resin coating (2) coated on the inner surface of the paper vibration plate (1), the synthetic resin coating (2) contains the collagen particle 3 in a uniform distribution inside.
상기 콜라겐이 함유된 합성수지계도료를 상기 종인진동판에 코팅막으로 형성시키는 방법으로는 하기의 화학식에 따라 저점도의 기본수지와 가교제를 결합시켜 고농도(high solid)화 시킨다.The method of forming the collagen-containing synthetic resin paint as a coating film on the vibrating plate is made of a high concentration by combining a low viscosity basic resin and a crosslinking agent according to the following formula.
상기 합성수지계도료에 함유된 콜라겐(collagen)은 천연 단백질계 섬유를 초미립화한 분말로서 뼈, 힘줄, 피부, 어류 등에서 추출하고 복잡한 가로무늬 구조를 지니고 있으며, 대략 30만의 분자량을 가지는 난용성 물질로서, 도료에 천연물과 같은 느낌을 주는 동시에 부드럽고 따뜻한 감촉을 부여하게 된다.Collagen contained in the synthetic resin coating (collagen) is a fine powder of natural protein-based fibers extracted from bones, tendons, skin, fish, etc. and has a complex horizontal pattern structure, as a poorly soluble substance having a molecular weight of approximately 300,000 This gives the paint a natural feel and gives it a soft and warm texture.
또한 상기 콜라겐입자(3)의 고흡습성에 의해 흠집 발생시 자연 복구된다.In addition, due to the high hygroscopicity of the collagen particles (3) is naturally recovered when scratches occur.
이상에서와 같이 본 발명에 따른 스피커용 진동판은, 코팅되는 도료의 충진재로서 천연소재인 콜라겐을 사용하기 때문에 부드럽고 미려한 외관을 지닐 수 있게 되는 효과가 있으며, 그와 동시에 콜라겐 입자의 물리적인 성질에 의해 내부 표면의 긁힘 등이 방지되는 탁월한 효과가 있다.As described above, the diaphragm for the speaker according to the present invention has the effect of having a smooth and beautiful appearance because it uses collagen, which is a natural material, as a filler of the coating material to be coated, and at the same time by the physical properties of the collagen particles It has an excellent effect of preventing scratches and the like on the inner surface.
또한, 고내부손실을 부여하여 노이즈(noise)의 발생을 최소화 시킬 수 있는 유용한 효과가 있다.In addition, there is a useful effect to minimize the occurrence of noise (noise) by giving a high internal loss.
