Description

扬声器及其制造方法和发声方法 技术领域
本发明涉及声音领域，特别涉及一扬声器及其制造方法和发声方法。
背景技术
扬声器是一种能够将音频信号转换为声波的换能器，现有的扬声器包括一个上部框架、一个下部框架、一个振膜、一个悬边、一个弹波、一个音圈以及一个磁回系统，该上部框架的中部具有一个穿孔而使该上部框架呈环形，该悬边的外侧和内侧分别延伸以被连接于该上部框架和该振膜而保持该振膜于该上部框架的该穿孔，该磁回系统被安装于该下部框架，该音圈的下端部和该磁回系统相互磁性交流地连接，该弹波的外侧和内侧分别延伸以被连接于该下部框架和该音圈，该上部框架和该下部框架相互安装，并且该音圈的上端部被连接于该振膜。当该音频信号被输入时，基于电磁感应原理，该磁回系统能够驱动该音圈沿着该扬声器的中心轴线往复运动，以允许该音圈带动该振膜同步地沿着该扬声器的中心轴线往复运动而鼓动空气以产生声波，在该扬声器被带动往复运动时，该悬边用于限制该振膜的冲程和限制该振膜沿着该扬声器的中心轴线往复运动以避免该振膜向四周偏移，同时，该弹波用于限制该音圈沿着该扬声器的中线轴线往复运动以避免该音圈向四周偏移。
然而，由于该扬声器的该弹波和该振膜是分体式结构，且二者通常是由不同的材料制成的，因此该弹波的弹力和该振膜的弹力存在差异，尤其是该振膜的弹力会大于该弹波的弹力。而该振膜和该弹波在弹力方面存在的差异导致该振膜在被该音圈带动而做往复运动时速度不均匀。另外，在该音圈被该磁回系统驱动而往复运动时，该弹波会对该音圈产生拉扯力，例如当该磁回系统驱动该音圈向上运动时，该弹波会对音圈产生一个向下的拉扯力，这使得该磁回系统需要提供足够大的磁力才能够克服该弹波对该音圈造成的拉扯力而保证该振膜的冲程。
