Description
제1도는 본 발명에 의한 스피커용 진동판 제조 방법을 나타내는 공정도.1 is a process chart showing the diaphragm manufacturing method for a speaker according to the present invention.
본 발명은 스피커용 진동판 및 그 제조 방법에 관한 것으로서, 특히, 갑각류의 껍질에서 주로 추출하는 키틴(chitin)을 탈 아세틸화하여 얻은 키토산(chito acid)을 제조 원료로 사용하는 스피커용 진동판 및 그 제조 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diaphragm for a speaker and a method for manufacturing the same. In particular, a diaphragm for a speaker using chito acid obtained by deacetylation of chitin extracted mainly from shells of crustaceans, and its manufacture. It is about a method.
일반적으로 스피커용 진동판에 요구되는 물성으로는 탄성률과 내부 손실율이 있으며 탄성률이 높은 진동판을 사용한 스피커는 박력감 있는 음질을 출력할 수 있고, 내부손실율이 큰 진동판을 사용한 스피커는 진동판이 필요음역만을 진동한 후 더 이상의 진동을 하지 않으므로 불필요한 잡음이나 잔향이 줄어들게 되어 원음 그대로를 효과적으로 출력하게 된다.In general, the properties required for the diaphragm for the speaker include elastic modulus and internal loss ratio, and a speaker using a diaphragm having a high elastic modulus can output powerful sound quality, and a speaker using a diaphragm with a large internal loss ratio requires a diaphragm to vibrate only the required range. Since no more vibration, unnecessary noise or reverberation is reduced, and the original sound is effectively output.
그런데, 종래에 스피커용 진동판 제조 원료로 주로 사용하던 펄프나 폴리프로필렌 등은 상기한 물성들을 어느 정도 만족시키는 편이나 보다 우수한 음질을 출력하는 스피커가 요구되어짐에 따라 보다 높은 탄성률과 보다 큰 내부손실을 갖는 진동판 재료의 필요성이 대두되었다.However, pulp and polypropylene, which are conventionally used as a raw material for manufacturing diaphragm for speakers, satisfy some of the above properties, but require a speaker that outputs better sound quality, resulting in higher elastic modulus and greater internal loss. There is a need for a diaphragm material having.
본 발명은 상기와 같은 필요성을 감안하여 안출한 것으로서, 탄성률 및 내부손실율 면에서 우수한 물성을 갖고 있어 스피커용 진동판의 재료로 적합한 키토산을 원료로 하여 진동판을 제조함으로서 우수한 음질의 스피커를 얻을 수 있는 스피커용 진동판 및 그 제조 방법을 제공하는데 그 목적이 있다.The present invention has been made in view of the necessity as described above, and has excellent physical properties in terms of elastic modulus and internal loss rate, so that a speaker having excellent sound quality can be obtained by manufacturing a diaphragm using chitosan, which is suitable as a material for a diaphragm for a speaker. An object of the present invention is to provide a diaphragm for use and a manufacturing method thereof.
상기와 같은 목적을 달성하기 위한 본 발명에 의한 스피커용 진동판은 키토산(chito acid)을 원료로 하여 제조된 것을 특징으로 한다.Speaker diaphragm according to the present invention for achieving the above object is characterized in that the chito acid (chito acid) produced as a raw material.
또한, 본 발명에 의한 스피커용 진동판 제조방법은 키틴(chitin)을 탈 아세틸화하여 생성된 키토산(chit acid) 원료를 희산성 수용액에 용해시켜 졸(so1)화하는 제1과정과, 겔(gel) 상태의 필름(film) 또는 시트가 되도록 상기 졸을 1차 건조시키는 제2과정과, 상기 필름 또는 상기 시트를 예비 성형하여 2차 건조시키는 제3과정과, 열 프레스로 마무리 성형하여 완전 건조시키는 제4과정과, 불필요한 부분을 절단하는 제5과정으로 이루어지는 것을 특징으로 한다.In addition, the method for manufacturing a diaphragm for a speaker according to the present invention is a first process of dissolving chito acid (chit acid) produced by deacetylation of chitin in a dilute aqueous solution and sol (so1), and gel (gel) A second process of first drying the sol to form a film or sheet in a) state, a third process of preforming the film or the sheet to a second drying, and a final process of hot pressing to complete drying And a fourth process, and a fifth process of cutting unnecessary portions.
이하, 첨부한 도면을 참조하여 본 발명의 실시예를 보다 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 의한 스피커용 진동판은 2종류의 강력한 수소 결합을 하고 있어 강고한 결정체를 이루는 천연 고분자 물질인 키토산을 원료로 사용하여 제조되며 키토산의 일반식은 하기와 같다.The diaphragm for a speaker according to the present invention has two kinds of strong hydrogen bonds, and is manufactured using chitosan, which is a natural polymer material that forms a strong crystal, as a raw material. The general formula of chitosan is as follows.
또한, 본 발명에 의한 스피커용 진동판 제조 방법을 제1도에 도시한 공정도를 참조하여 설명하면 다음과 같다.In addition, the method of manufacturing a diaphragm for a speaker according to the present invention will be described with reference to the process diagram shown in FIG.
먼저, (가)에 도시된 바와 같이 키틴(chitin)을 탈 아세틸화하여 생성된 키토산(chito acid) 윈료를 메타아크릴산 1농도%를 함유한 희산성 수용액에 용해시켜 졸(sol)화 한다.(제1과정) 다음, (나)에 도시된 바와 같이 상기 졸을 1차 건조시켜 겔(gel) 상태의 필름(film) 또는 시트가 되도록 한다. (제2과정) 그리고, (다)에 도시된 바와 같이 상기 필름 또는 상기 시트에 압력을 가하여 일정 형태로 예비 성형을 한 후 2차 건조시킨다.(제3과정) 그리고, (라)에 도시된 바와 같이 상기 예비 성형된 상기 필름 또는 상기 시트를 열 프레스로 마무리 성형하여 완전 건조시킨다.(제4과정) 다음, (마)에 도시된 바와 같이 불필요한 부분을 절단하고 연마하여 진동판 바디를 완성한다.(제5과정)First, as shown in (A), the chito acid winch produced by deacetylation of chitin is dissolved in a dilute aqueous solution containing 1% by weight of methacrylic acid to sol. First Step) Next, as shown in (b), the sol is first dried to form a film or sheet in a gel state. (Second Step) Then, as shown in (C), pressure is applied to the film or the sheet to form a preform in a predetermined form, followed by secondary drying. As described above, the preformed film or sheet is finished by hot pressing and completely dried. (Fourth Step) Next, as shown in (e), unnecessary parts are cut and polished to complete the diaphragm body. (5th course)
상기와 같은 본 발명에 의한 스피커용 진동판 및 그 제조 방법은 표 1에 도시된 바와 같이 스피커용 진동판 재료에 적합한 고 탄성률 및 고 내부손실율의 물성을 지닌 키토산을 제조 원료로 사용하여 진동판을 제조함으로서 우수한 음질을 출력하는 스피커를 얻을 수 있는 효과가 있다.As described in Table 1, the diaphragm for a speaker and a method of manufacturing the same according to the present invention are excellent by producing a diaphragm using chitosan having high elastic modulus and high internal loss property suitable for a diaphragm material for a speaker as a raw material. It is effective to obtain a speaker that outputs sound quality.
