Description

一种电枢结构 技术领域
本申请实施方式涉及电枢结构技术领域,特别是涉及一种电枢结构。
背景技术
动铁喇叭作为高端的声学原件,由于生产成本较高导致其在价格敏感的消费电子市场表现差强人意,如何改善生产工艺,产品设计,降低生产成本,从而降低市场售价,使其能在消费电子市场大放异彩是从业者致力解决的。一般来讲,动铁喇叭的设计和生产是以喇叭外形尺寸(决定了喇叭的声学性能)和阻抗来区分的,也就是说,同样尺寸的动铁喇叭会对应若干种不同的阻抗(由音圈的,线材,圈数和线径决定)来满足不同的应用场合。目前动铁喇叭中的电枢的组装主要方式是依靠工装定位磁性元件以及电枢的相对位置后再进行电阻焊接,而由于电枢和磁性元件的接触面均为平面,因此为了达到电枢组装的工艺要求,首先需要对电枢进行左、右、前这3个自由度的定位,而后再由作业员手动辅助定位上下的自由度,其技术方案是:磁性元件定位后,将U型电枢一边穿过马达,另一边进入位于磁性元件上方的定位工装,再由作业员用镊子顶住电枢尾部,最后进行焊接将磁性元件和电枢接合在一起。
但是发明人在实现本申请的过程中,发现现有技术存在以下技术问题:在现有技术中,动铁喇叭中的电枢结构一般都包括导磁铁芯或者导磁锷铁,为了使得导磁铁芯或者导磁锷铁能实现较好的导磁作用,导磁铁芯或者导磁锷铁一般都需要设计成环形,同时电枢上的一部分或者固定部需与环形导磁铁芯或者导磁锷铁的一外侧壁固定,由此导致电枢结构的整体厚度较大,因此环形结构的导磁铁芯或者导磁锷铁无形中增大了电枢结构的整体大小,也使得材料成本更高。
