Abstract

본 발명은 전대역(全帶域)에서 우수한 주파수특성을 갖는 전기-음향변환기용 진동판 및 그 제조방법을 제공함에 있다.The present invention provides a diaphragm for an electro-acoustical transducer having excellent frequency characteristics in a full band and a method of manufacturing the diaphragm.

플리머박막으로된 진동판기재에는 전체의 주파수범위에 걸쳐서 만족하게 사용될 수 있는 스테인레스스틸피막을 형성한 후, 그 피막에는 Cu, Al, Cr, Ti 중에서 선택된 어느 하나의 금속물질피막 이나 혹은 TiN, CuN 중에서 선택된 어느하나의 질화물 피막을 형성한 것이다.A stainless steel film which can be satisfactorily used over the entire frequency range is formed on the diaphragm substrate made of a plummer thin film, and then a coating film of any metal selected from Cu, Al, Cr and Ti, or a film of TiN, CuN The nitride film is formed.

이에 의해 전체주파수범위에 걸쳐 만족하게 사용될 수 있으며, 내열, 내습, 내후성에 강하고, 가벼우며 또한 금속층의 산화, 긁힘등의 방지효과가 큰 진동판을 얻을 수가 있다.As a result, it is possible to obtain a diaphragm which can be satisfactorily used over the whole frequency range, is resistant to heat, humidity and weathering, is light, and has a large effect of preventing oxidation and scratching of the metal layer.

Description

전기-음향변환기용 진동판과 그 제조방법Diaphragm for electro-acoustical transducer and its manufacturing method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제 1 도는 본 발명에 따른 진동판이 돔형 스피커에 응용된 일예를 개략적으로 도시한 단면도이고, 제 2 도는 제 1 도의 Ⅰ-Ⅰ선 방향에 따른 진동판의 부분확대단면도이다.FIG. 1 is a cross-sectional view schematically showing an example in which a diaphragm according to the present invention is applied to a dome-shaped speaker, and FIG. 2 is a partially enlarged sectional view of a diaphragm according to a direction I-I in FIG.
