Description

一种用于扬声器的磁路系统及扬声器 技术领域
本发明涉及电声产品技术领域，更具体地，本发明涉及一种用于扬声器的磁路系统及具有该种磁路系统的扬声器。
背景技术
扬声器的磁路系统一般包括导磁板(或者称之为盆架)、中心磁铁、边磁铁、中心华司和边华司，其中，中心磁铁设置在导磁板表面的中心位置上，边磁铁在导磁板上围绕中心磁铁设置，中心华司设置在中心磁铁的背向导磁板的表面上，及边华司设置在对应边磁铁的背向导磁板的表面上，且中心磁铁、中心华司的一体结构与边磁铁、边华司的一体结构之间形成有用于放置音圈的磁间隙。
目前，磁路系统的上述各组件之间都是通过胶水粘接在一起，而且整个磁路系统与扬声器的外壳之间也是通过胶水粘接在一起，因为胶水粘接具有工艺简单、无需尖端设备实施的优点，但是胶水粘接却存在连接强度相对较差的问题，而且即使采用粘接性能非常好的胶水也可能会因环境因素的影响而无法达到例如是焊接等机械连接的连接强度。
发明内容
本发明的一个目的是提供一种用于扬声器的磁路系统，以提高磁路系统各组件之间的连接强度。

优选的是，所述边华司具有两个相对设置的所述弯折部。
优选的是，所述磁路系统具有两块相对设置的边磁铁，且所述两块边磁铁与所述两个弯折部十字交叉布置。

优选的是，所述边华司的华司本体设置有预制开口，所述扬声器的中壳上设置有与所述预制开口一一对应配置的热熔柱，所述热熔柱穿过对应预制开口，并通过所述热熔柱的热熔将所述边华司铆接固定在所述中壳上。
优选的是，所述边华司的华司本体设置有至少两个所述预制开口。
本发明的发明人发现，在现有技术中，存在磁路系统各组件之间连接不可靠的问题。因此，本发明所要实现的技术任务或者所要解决的技术问题是本领域技术人员从未想到的或者没有预期到的，故本发明是一种新的技术方案。本发明的磁路系统及扬声器通过使边华司形成朝向导磁板弯折的弯折部，并使弯折部与导磁板焊接固定在一起，可以有效防止边华司、导磁板和夹持于二者之间的边磁铁因胶水粘接强度不够而松散脱落，进而实现了提高磁路系统本身的连接强度的目的。

应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
本发明为了解决现有磁路系统存在连接不可靠的问题，提出了一种新的用于扬声器的磁路系统，如图1至图6所示，本发明的磁路系统1包括导磁板11、中心磁铁12、中心华司14、边磁铁13和边华司15，其中，中心磁铁12设置在导磁板11表面的中心位置上，边磁铁13在导磁板11上围绕中心磁铁12设置，中心华司14设置在中心磁铁12的背向导磁板11的表面上，该背向导磁板11的表面应理解为是与中心磁铁12贴合在导磁板11上的表面相对的表面，及边华司15设置在对应边磁铁13的背向导磁板11的表面上，该背向导磁板11的表面应理解为是与对应边磁铁13的贴合在导磁板11上的表面相对的表面，且中心磁铁12、中心华司14的一体结构与边磁铁13、边华司15的一体结构之间形成用于放置音圈31的磁间隙；除此之外，本发明对边华司的结构进行了改进，具体为：该边华司15包括华司本体151和与华司本体151承接的弯折部152，边华司15通过华司本体151设置在对应边磁铁13的背向导磁板11的表面上，弯折部152则经华司本体151的侧面15a从上至下朝向导磁板11弯折，即弯折部152在从上至下的方向P1上延伸至导磁板11处，且弯折部152与导磁板11焊接固定在一起，而且优选是通过超声波焊接或者激光焊接固定在一起。在此，磁路系统1可以设置一块边磁铁13，也可以设置多块边磁铁13，而在设置一块边磁铁13的情况下，可以设置一块边华司15，形成一块边华司15对应一块边磁铁13的结构，也可以设置多块边华司15，形成所有边华司15对应一块边磁铁13的结构；而在设置多块边磁铁13的情况下，可以设置一块边华司15对应所有边磁铁13，也可以设置与边磁铁13一一对应的边华司15。
在本发明的磁路系统中，边华司15设置有朝向导磁板11弯折的弯折部152，且弯折部152与导磁板11焊接固定在一起，由于通过机械手段焊 接固定连接的连接强度明显高于胶水粘接的连接强度，因此该种结构不仅可以保证边华司15与导磁板11之间的可靠连接，还可以向位于二者之间的边磁铁13施加夹持力，进而有效防止边华司15、导磁板11和夹持于二者之间的边磁铁13因胶水粘接强度不够而松散脱落，实现提高磁路系统1本身的连接强度的目的。从另一方面讲，该种结构可以降低对磁路系统1上述组件间的粘接强度的要求，还可以减少磁路系统1与扬声器外壳之间的粘接面的面积及/或数量，进而缩减需要预留的涂胶槽，这有利于对扬声器的内部空间进行有效利用，以能够在扬声器外形尺寸不变的情况下增大磁路系统，获得更好的声学性能，或者在不降低声学性能的情况下实现扬声器的更小型设计。进一步地，对于该种边华司15设置弯折部152的结构，可以通过弯折部152起到部分边磁铁的作用，这能够在一定程度上获得增强磁力的效果。
为了使弯折部152的设置不会导致磁路系统1安装空间的增大，如图1和图2所示，该弯折部152的外表面优选是相对导磁板11的侧面11a向内缩进；或者，该弯折部152的外表面与导磁板11的侧面11a平齐。这可以使得弯折部152在导磁板11所在平面上的投影位于导磁板11所占据的最大范围内，该最大范围即为由导磁板11在所在平面的各方向上的最大尺寸确定的范围，因此，该种结构可以保证弯折部152的设置不会导致磁路系统1安装空间的增大。
为了便于进行焊接操作，如图1、图2和图6所示，该导磁板11的侧面11a可以具有向内凹陷、且上下贯通的凹槽111，这样，弯折部11便可沿从上至下的方向P1(在扬声器中，习惯将中心华司14指向导磁板11的方向称之为向下的方向)伸入凹槽111中。该种结构可使操作人员能够在磁路系统1的外部进行焊接操作，这对于尺寸很小的磁路系统而言是非常有利的。
图1至图6示出了一种磁路系统1具有一块对应所有边磁铁13的边华司15的实施例，且该边华司15的华司本体151为环绕中心华司14的环形，该种边华司15不仅便于进行磁路系统1与扬声器外壳之间的粘接，而且可以使磁路系统1具有相对封闭的结构，在此基础上，该边华司15优选 是具有至少两个弯折部152，以对边华司15与导磁板11之间应力集中的部位进行分散，进而进一步提高二者之间的连接强度。进一步地，兼具考虑提高边华司15与导磁板11之间的连接强度及尽可能地减少弯折部152对磁路系统1内部空间的占用，如图1至图6所示，该边华司15优选是具有两个相对设置的弯折部152。更进一步地，如图1至图6所示，该磁路系统1具有两块相对设置的边磁铁13，且两块边磁铁13与两个弯折部152十字交叉布置，该种结构可以实现对磁路系统1内部空间的合理利用，而且可以使弯折部152作为边磁铁13使用的作用得以较好的发挥。
本发明除了提高磁路系统1本身的连接强度外，还提供了一种能够提高磁路系统1与扬声器外壳(具体为如图1至图6所示的中壳21)之间连接强度的结构，这样便可从多个方面保证不会出现磁路系统在扬声器跌落时松散脱落的现象。为此，如图1至图3所示，在本发明中，边华司15的华司本体151设置有供热熔柱211穿过，以通过热熔铆接固定边华司15的预制开口153，即通过对热熔柱211热熔形成覆盖预制开口153的蘑菇头部，进而将华司本体151固定在蘑菇头部与设置热熔柱211的外壳之间的铆接固定结构。边华司15的华司本体151优选是设置有至少两个预制开口153，而在磁路系统1设置一块具有环形华司本体151的边华司15的实施例中，为了避免热熔柱211与弯折部152和边磁铁13之间的位置干涉，该预制开口153优选是设置在边华司15的华司本体151的四个边角处，特别是在四个边角处各设置一个预制开口。
为了便于进行磁路系统1在扬声器外壳中的安装，如图1至图3所示，该预制开口153特别是通向华司本体151的侧面15a，以在侧面15a上形成缺口。
本发明的另一个目的是提供一种如图4至图6所示的扬声器，该扬声器具有本发明提供的上述磁路系统1。由于本发明的磁路系统1自身具有较高的连接强度，因此本发明扬声器具有跌落时磁路系统1各组件不易松散脱落的优点。如图1至图3所示，扬声器的外壳通常具有中壳21和上壳22，还可能具有下壳(图中未示出)，其中，中壳21用于安装磁路系统1及包括音圈31、振膜32和球顶部33(或者称之为补强部)在内的振动系 统，上壳22与中壳21配合形成具有出声孔4的前声腔，下壳用于将磁路系统1封装在后声腔内，因此，磁路系统1在进行扬声器的组装时具体是与中壳21和下壳粘接固定在一起。
为了提高磁路系统1与扬声器外壳之间的连接强度，以进一步提升扬声器的磁路系统抗跌落性能，本发明扬声器优选是采用上述的边华司15设置有预制开口153的磁路系统1，对应地，扬声器的中壳21上应该设置与预制开口153一一对应配置的热熔柱211，热熔柱211穿过对应预制开口153，并通过热熔柱211的热熔将边华司15铆接固定在中壳21上，这样便可在将边华司15粘接固定在中壳21的基础上，再通过机械铆接结构提高二者之间的连接可靠性。为了进一步提高边华司15与中壳21之间的连接强度，优选的是，边华司15的华司本体151设置有至少两个预制开口153，而且在磁路系统1设置一块华司本体151为环形的边华司15的实施例中，该边华司15的华司本体151优选是在四个边角处各设置一个预制开口153。
上述各实施例主要重点描述与其他实施例的不同之处，但本领域技术人员应当清楚的是，上述各实施例可以根据需要单独使用或者相互结合使用。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
