Description

音圈组件及扬声器 技术领域
本发明涉及声电设备技术领域，特别涉及一种音圈组件及扬声器。
背景技术
微型扬声器广泛应用于手机、笔记本电脑、助听器等便携式电子设备。随着这些便携式电子设备的快速发展，人们对应用于其中的微型电声器件的要求也越来越高。
其中，音圈为微型扬声器的重要部件；为了使扬声器获得更大的振幅，需要将球顶到华司的距离增加，但是由于靠近球顶一侧的音圈距离磁间隙比较远，所以导致BL值降低，其对音圈灵敏度提升减小，但是为了保证内核的灵敏度及音圈与振膜能够刚性连接，音圈需要持续增加高度，导致音圈的重量不断增大，使音圈的灵敏度降低，而且对于部分扬声器来说，其通常采用无连接线圈(即音圈未绕制在音圈骨架上)，而无连接线圈通常采用一绕线一体绕制形成。这样，无连接线圈作为一个一体绕制成型的部件，不利于对音圈进行监测和控制，从而不利于提高扬声器的声学性能。

本发明提出一种音圈组件。
可以理解的是，本发明音圈组件用于扬声器；其属于扬声器的振动系统的一部分。具体而言，如图1所示，所述扬声器通常包括振动系统和磁路系统，其中，扬声器的结构形式多种多样，以下仅举例进行说明，但其并不用于限定本发明音圈组件的应用范围。
可选地，如图1所示，所述磁路系统包括中心磁路4和边磁路5，所述中心磁路4一般包括中心磁铁及设置于中心磁铁上的中心华司3，所述边磁路5一般包括边磁铁及设于边磁铁上的华司，其中，中心磁路4与边磁路5之间形成磁路间隙(图未标)。所述振动系统包括振膜6和音圈组件，音圈组件的一端连接于振膜6，另一端设于磁路间隙内。
其中，音圈组件包括主体音圈20和与所述主体音圈20连接的连接线圈10，所述主体音圈20用于与外部电路连接，所述主体音圈20包括第一音圈21和第二音圈22；所述第一音圈21采用第一线材绕制形成，所述第一线材为外涂有自粘漆的导电线材；所述第二音圈22采用第二线材绕制形成，所述第二线材为外涂有自粘漆的导电线材，所述第一音圈21和所述第二音圈22紧邻绕制形成且通过第一线材和第二线材表面的自粘漆粘接在一起，所述第一音圈21与所述第二音圈22串联或并联连接；
所述连接线圈10采用第三线材绕制形成，所述第三线材为外涂有自粘漆的线材，所述第三线材的密度小于或者等于第一线材、第二线材的密度；
所述连接线圈10与所述第一音圈21紧邻绕制形成且通过第三线材和第一线材表面的自粘漆粘接在一起。
所述连接线圈10与所述第一音圈21紧邻绕制形成且通过第三线材和第一线材表面的自粘漆粘接在一起，第一音圈21和所述第二音圈22紧邻绕制形成且通过第一线材和第二线材表面的自粘漆粘接在一起，连接线圈10与第一音圈21之间、第一音圈21与第二音圈22之间的粘结力较高，从而可提高连接线圈10与第一音圈21、第一音圈21与第二音圈22之间的连接强度；而且，还可提高耐温性能。
此外，还可避免在连接线圈10与第一音圈21之间、第一音圈21与第二音圈22之间涂覆粘接胶层，从而可避免该粘接胶层对扬声器的灵敏度造成影响，有利于提高扬声器的灵敏度。
所述第一音圈21采用第一线材绕制形成，所述第二音圈22采用第二线材绕制形成，所述连接线圈10采用第三线材绕制形成，所述第三线材的密度小于或者等于第一线材、第二线材的密度；可以理解为连接线圈10所选用的材质密度小于或者等于主体音圈20的材质密度，能够有效降低音圈组件的的重量，提高振动系统的灵敏度。
在具体实施例中，所述第一音圈21与第二音圈22既可以串联设置，也可并联设置，其均可以提高扬声器的声学性能；以下分别进行说明。
在部分实施例中，所述第一音圈21与第二音圈22串联。
可以理解的是，当所述第一音圈21与第二音圈22串联时，所述第一音圈21的出线端与第二音圈22的入线端电连接，或者，所述第一音圈21的入线端与第二音圈22的出线端电连接，以使所述第一音圈21与第二音圈22串联。
如此，在音圈组件工作的过程中，根据第一音圈21与第二音圈22间的电动势差异对音圈组件在磁路间隙中的位置进行建模，从而可实时计算出音圈组件所处的位置，从而可对扬声器的振动系统进行实时优化，以提升扬声器的声学性能。
具体的，在两个音圈串联时，第一音圈21及第二音圈22由于在磁路间隙的磁场中的位置不同，因此穿过第一音圈21及第二音圈22的磁感应强度也不同，从而第一音圈21及第二音圈22产生的感应电动势也不同，通过检测第一音圈21与第二音圈22连接处的电压差，可实时计算得出第一音圈21与第二音圈22在磁场中的相对位置，即音圈组件整体在磁场中的振动位置。
若音圈组件在振动过程中偏离预设位置，则第一音圈21与第二音圈22的位置均会发生变化，此时第一音圈21与第二音圈22产生的感应电动势会发生变化，即第一音圈21与第二音圈22连接处的电压差发生变化，通过检测到电压差的变化可计算出音圈组件的整体偏移，从而可通过外部输入补偿电流的方式使音圈组件重新回到预设位置，实现对音圈组件位置的矫正，以提高音圈组件在磁场中的振动稳定性和对称性，从而有效提高扬声器的整体 声学性能。
在部分实施例中，所述第一音圈21与第二音圈22并联。
需要说明的是，当所述两音圈并联连接时，在相同阻值的前提下，可使得音圈厚度更薄，磁间隙可以更窄，具有更高的BL值，进而提高振动系统的灵敏度，提高发声单体的发声性能。
在该部分实施例中，需要将第一音圈21的入线端、出线端，及第二音圈22的入线端、出线端分别与外部电路连接；此时，通过控制第一音圈21的入线端、出线端，及第二音圈22的入线端、出线端的排布，可使音圈组件振动时，该四条引线对振动系统的反作用力较对称，从而大大减小产品的偏振，改善失真、改善音质。
在一个实施例中，所述第三线材为导电线材或者绝缘线材，所述连接线圈10与主体音圈20之间不通电，也不与外部电路连接，只起到支撑作用，使主体音圈20全部位于磁间隙中，提高BL值，同时主体音圈20产生的热量无法直接传递到振膜6或者定心支片上，能够有效避免振膜6或者定心支片由于温度过高而损坏。
在一个实施例中，所述主体音圈20的高度大于连接线圈10的高度，在一定程度上，可以减小音圈组件的重量，提高音圈的灵敏度。
在一个实施例中，所述第一线材和第二线材为外涂有自粘漆的铜漆包线或者铜包铝漆包线时，所述第三线材为外涂自粘漆的铜包铝漆包线或者铝漆包线。可以理解为第一线材、第二线材及第三线材从选材方面来实现减小第三线材的重量，进而实现减小音圈组件的总体重量，同时第一线材、第二线材和第三线材均为铜包铝漆包线时，可使第三线材的铜的百分比重小于第一线材和第二线材的铜的百分比重，从而尽量减小第三线材的重量，提高音圈的灵敏度。
在一个实施例中，所述第一线材和所述第二线材的线径相同，所述第三线材的线径小于所述第一线材、第二线材的线径，该设置尽量减小连接线圈的高度和重量，减小对主体音圈20上下运动产生重量上的负担。
在一个实施例中，所述连接线圈10的厚度小于所述主体音圈20的厚度；所述连接线圈10位于第一音圈21的顶面的内侧，所述连接线圈10的外侧表面与所述第一音圈21的顶面的外侧之间形成容置空间；或者，所述连接线圈 10位于所述第一音圈21的顶面的外侧，所述连接线圈10的内侧表面与所述第一音圈21的顶面的内侧之间形成容置空间；或者，所述连接线圈10位于第一音圈21的顶面的中间位置，所述连接线圈10的外侧表面与沿所述第一音圈21的顶面的外侧之间，以及所述连接线圈10的内侧表面与所述第一音圈21的顶面的内侧之间均形成容置空间。第一音圈21顶部的上表面面积大于连接线圈10底部的下表面面积，增加了连接线圈10的底部与第一音圈21的顶部连接强度，使连接线圈10与第一音圈21之间粘接更加的牢固。
在一个实施例中，所述连接线圈10位于所述第一音圈21顶面的内侧，所述第一音圈21的顶部对应设有向第一音圈21内侧和顶面开口的凹槽，所述连接线圈10的底面和下端外侧面与第一音圈21的凹槽的底面和侧面粘接，连接线圈10与第一音圈21粘接位置不限于连接线圈10的底面与第一音圈21的顶面，也可以使连接线圈10的底部外侧表面与第一音圈21的内侧表面进行粘接，增加了连接线圈10和第一音圈21的粘接强度；
或者，所述连接线圈10位于所述第一音圈21顶面的外侧，所述第一音圈21的顶部对应设有向所述第一音圈21外侧和顶面开口的凹槽，所述连接线圈10的底面和下端内侧面和所述第一音圈21的凹槽的底面和侧面粘接，同理，连接线圈10与第一音圈21粘接位置不限于连接线圈10的底面与第一音圈21的顶面，连接线圈10的底部内侧表面与第一音圈21的外侧表面进行粘接，增加了连接线圈10和第一音圈21的粘接强度。
在一个实施例中，所述第一线材、所述第二线材、所述第三线材为圆形线材或矩形线材，应理解接线圈10、第一音圈21和第二音圈22的线材形状可进行随意选择，自行组合。在其他实施例中，所述第一线材、第二线材、第三线材不限于所例举的形状，所述第一线材、第二线材、第三线材也可为其他形状，在此不再赘述。
在部分实施例中，如图2所示，连接线圈10的线型为圆形，第一音圈21和第二音圈22的线型为圆形，方便连接线圈10、第一音圈21、第二音圈22在同一绕线工装上绕制。
在部分实施例中，如图3所示，连接线圈10的线型为圆形，所述第一音圈21和第二音圈22的线型为矩形，增大了第一音圈21与第二音圈22的接触面积，提高了第一音圈21与第二音圈22的连接强度。
在部分实施例中，如图4所示，连接线圈10的线型为矩形，所述第一音圈21和第二音圈22的线型均为矩形，连接线圈10与第一音圈21的连接面、第一音圈21与第二音圈22的连接面的接触面增大，当连接线圈10、第一音圈21、第二音圈22的线型均为矩形时，增加了连接线圈10与第一音圈21之间的连接面积、第一音圈21与第二音圈22之间的连接面积，使连接线圈10与第一音圈21的连接强度、第一音圈21与第二音圈22的连接强度得到了提升，提高了扬声器的整体声学性能。
一种扬声器，包括振动系统和磁路系统，所述振动系统包括振膜6和音圈组件，所述音圈组件为以上所述的音圈组件，所述连接线圈10的顶面与振膜6连接，所述主体音圈20伸入所述磁路系统的磁间隙中。由于发明扬声器采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
在扬声器的工作过程中，音圈组件通电，通电的音圈组件在该磁场中受力而产生振动，振动的音圈组件会带动振膜6一起振动，从而使振膜6策动空气发声。
在另一实施例中，进一步的，所述振动系统还包括定心支片，所述定心支片包括内固定部、外固定部和连接所述内固定部和所述外固定部之间的形变部；所述振膜6由内到外包括中心部、折环部和边缘部，所述内固定部与所述中心部连接，所述外固定部与所述边缘部连接；所述连接线圈10的顶面与所述内固定部连接。所述定心支片用于稳定音圈组件的振动状态，起定心作用，以改善音圈组件的偏振现象，改善失真、改善音质。
