Description

一种骨架式线圈、动铁受话器以及动铁喇叭 技术领域
本申请实施例涉及声电器件技术领域，特别是涉及一种骨架式线圈、动铁受话器以及动铁喇叭。
背景技术
现有的受话器一般是指动铁受话器，其工作原理为：变化的音频电信号馈入线圈，线圈置于一个永磁体磁路的磁隙里，线圈因变化电流产生的变化电磁场力，亦即洛仑兹力的驱动而上下振动，并带动振动膜驱动前后空气，产生声波。
线圈一直是喇叭、受话器设计中的心脏部件，通过交流电压产生的磁场带动衔铁上下振动，再由传导杆带动膜片振动来压缩空气以实现电声转换。线圈作为动铁受话器中必不可少的零部件，线圈绕制使需要载体且绕制后的线丝不能松动。骨架是适用于动铁动铁受话器或者动铁喇叭线圈的载体。
图1所示为现有的动铁受话器的线圈骨架，该骨架包括铁芯1、绕线杆2和端子3。该骨架的端子3呈片状直线型结构。该端子3上部为线圈引线绕制的连接端，下部为对接电路的端子。现有的动铁受话器在组装完成后其整体的结构如图2所示，端子从动铁受话器外壳下方伸出连接电路板。而由于不同的受话器或者喇叭产品的性能要求，对这端子连接的要求不同，有的客户要求端子从外壳侧面伸出而不是底部伸出，以便于与不同的产品电路板对接。受话器组装完成后，在受话器端子与产品电路板对接时，需通过中间件软性电路板完成连接，其中，将部分端子与软性电路板通过手工的方式在显微镜下焊接在一起，该软性电路板的另一端引出后固定连接在受话器的电路板上。
上述现有的动铁受话器端子连接方式中，增加了软性电路板器件，在软性电路板焊接连接后产品体积增大，不利于产品推广。并且手工焊接的方式生产效率低，不适合大规模量产。同时，在端子和电路板焊接时会产生虚焊，存在质量隐患。
因此，现有的线圈和动铁受话器还有待于改进和发展。

本申请还涉及使用该骨架式音圈的动铁喇叭，该动铁喇叭包括封装外壳以及安装在该封装外壳中的如前所述的骨架式线圈。
该骨架式音圈与实施例1的骨架式音圈相同，在此不再赘述。
本申请通过改变受话器或者喇叭的线圈绕线骨架的结构，并对应该骨架结构改变封装外壳的下壳体的结构，省去了软性电路板器件并取消了手工焊接软性电路板的制程，同时改变了整个产品的组装工艺，实现快速组装的同时减小了产品体积。
组装过程，将第一导电端子40-1的方形第一连接部穿入下壳体51的安装槽52中，以及将第二导电端子40-2的方形第二连接部穿入下壳体51的安装槽中，使该第一连接部46和第二连接部伸出该下壳体51之外预设距离。此时，该音圈底部恰好与下壳体的底壁接触，最后利用激光熔接的方式将音圈与下壳体51接合在一起。
本申请实施例的骨架式线圈、动铁受话器以及动铁喇叭可实现线圈的快速组装和连接，减小受话器或者喇叭的体积。通过设置具有特殊结构的线圈骨架，无需软性电路板做连接即可解决产品组装时的对接问题，在组装时不仅省去了软性电路板器件并且也省去了手工焊接软性电路板的工序流程，提高了产品生产效率。同时，本申请的骨架式线圈、动铁受话器以及动铁喇叭因为减少了软性电路板组件，因此产品体积缩小，产品可以做的更小巧。
以上所述仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
需要说明的是，本申请的说明书及其附图中给出了本申请的较佳的实施方式，但是，本申请可以通过许多不同的形式来实现，并不限于本说明书所描述的实施方式，这些实施方式不作为对本申请内容的额外限制，提供这些实施方 式的目的是使对本申请的公开内容的理解更加透彻全面。并且，上述各技术特征继续相互组合，形成未在上面列举的各种实施方式，均视为本申请说明书记载的范围；进一步地，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本申请所附权利要求的保护范围。
