上期介绍了两种新材料,即碳纤维和强化烯烃做为扬声器振膜。本文分别介绍采用精细陶瓷的扬声器振膜,硼、钛复合振膜,石墨振膜。 4.采用精细陶瓷的扬声器振膜精细陶瓷与一般陶瓷相区别,它已经不采用不纯物甚多的天然材料、而选用成品,组成和结构能精确控制的高纯度人工材料, Two new materials were introduced in the previous issue, namely, carbon fiber and reinforced olefin as loudspeaker diaphragm. This article introduces the use of fine ceramic speaker diaphragm, boron, titanium composite diaphragm, graphite diaphragm. 4. The use of fine ceramic speaker diaphragm Fine ceramics and general ceramic phase difference, it does not use many impurities of natural materials, and the use of finished products, composition and structure can be precisely controlled high purity artificial materials,
