所述振动系统包括振膜组件7、音圈组件和定心支片6；所述音圈组件和所述定心支片6均在所述发声装置的振动方向上与所述振膜组件7连接固定，并且，在垂直于所述发声装置振动的方向上，所述定心支片6位于所述音圈组件的外侧；
所述磁路系统上设置有过线部22，连接在所述音圈组件上的锦丝线511从所述磁路系统穿出，并延伸到所述信号接入端子9处与所述信号接入端子9电性连接。
在该实施例中，外壳1作为整个发声装置的承载件，整体呈凹陷的结构，发声装置装配完成后将发声装置的其余部件限制在外壳1中。振动系统和磁路系统配合使发声装置产生振动。
其中，音圈组件上的锦丝线511从磁路系统上的过线部22引出，与信号接入端子9电连接。这样能够避免锦丝线511从磁路系统的上部绕过，消除了锦丝线511增加的结构厚度。并且减少了锦丝线511的弯折程度，避免在振动过程中锦丝线511发生断裂或损坏。
在一个实施例中，所述振膜组件7包括结合在一起的折环71和胴体72，所述音圈组件包括筒形的音圈骨架5以及缠绕在所述音圈骨架5外侧的音圈51，所述胴体72与所述音圈骨架5连接固定在一起.
在该实施例中，振膜组件7中的音圈骨架5固定连接在胴体上，以对音圈骨架5形成支撑。有音圈51在磁间隙中作用振动，带动音圈骨架5振动，音圈骨架5带动振膜组件7振动。
在一个实施例中，所述胴体与所述音圈骨架的轴向之间的夹角大于60°。在该角度范围内，能够使锥盆保持很小的斜度，接近平面。能从振膜组件7的结构上最大限度降低装置的高度。
在一个实施例中，如图1所示，所述磁路系统包括U铁2和永磁体3，所述U铁2包括底板和侧壁21，所述底板和侧壁21形成容置腔，所述永磁体3固定在所述容置腔内并与所述侧壁21间形成磁间隙；所述过线部22设置在所述U铁2的侧壁21上。
在该实施例中，U铁2和永磁体3间形成的磁间隙用于和通电后的音圈51相互配合作用，以产生振动。过线部22则用于引出锦丝线511.
在一个例子中，永磁体3的上部设置华司4，在华司4与侧壁21间形成磁间隙。
在一个实施例中，如图1,5所示，所述外壳1的底部设置有安装口11，所述安装口11内设置有卡件111，所述卡件111和所述U铁2的过线部22固定。
在该实施例中，U铁2安装时，从外壳1底部的安装口11放入，再将U铁2的底部从过线部22的位置与外壳1的底部进行固定。例如，可以通 过焊接或热熔的方式进行固定。
例如，卡件111为弯折结构，弯折结构与过线部22进行固定。
弯折结构的卡件111能够方便U铁在安装时的定位和与过线部22准确固定。
在一个实施例中，如图5所示，在固定后U铁2的底部和外壳1的底部在外侧齐平。
齐平的底部能够消除因U铁2的底部向外壳1外凸出时造成的额外装置高度。
其中，过线部22将侧壁21分为多个部分，而多个部分的侧壁更容易集中磁力线，以提升发声装置的性能。
在一个实施例中，如图1所示，U铁2的侧壁21为筒状结构，底板和与侧壁21的一端固定形成容置腔。侧壁21上的多个均匀分布的过线部22能够满足音圈51向不同方向引出的锦丝线511与信号接入端子9连接。
在一个实施例中，如图1所示，侧壁21上设置有4个过线部22。4个过线部22将侧壁21分为均匀的4段，能够更优地集中磁路系统中的磁力线。
在其他例子中，过线部22可以为U形、矩形和V形中的一种，也可以为其他形状。不同的过线部22的形状都能满足过线部22的引出锦丝线511以降低装配高度的目的。
在其他例子中，过线部22还可以是缺口、槽口和通孔结构，也可以是各结构相互组合。
例如，侧壁21上设置多个沿侧壁均匀分布的通孔，将锦丝线511从通孔中引出，也能满足降低装配高度的目的。
在一个实施例中，如图2所示，所述定心支片6的内侧设置有筒状部63，所述筒状部63的顶部与所述振膜组件7连接；所述定心支片6还包括用于与所述锦丝线511固定的第一固定部622和第二固定部623。
在该实施例中，定心支片6在安装时，筒状部63的顶部和振膜组件7固定连接。
其中，音圈骨架5的上部也固定在振膜组件7上，振膜组件7中部形 成有中空的结构，音圈骨架5在振膜组件7上的中空结构中固定。
例如，音圈骨架5的上部的外侧壁与中空结构的内壁贴合固定。
在振膜组件7的中空结构上设置防尘膜8进行封闭。
在一个实施例中，所述第一固定部622为所述筒状部63的底部，所述第二固定部623位于所述定心支片6与所述外壳1的第一连接点处；所述锦丝线511从U铁2的过线部22穿出后，分别与所述第一固定部622和所述第二固定部623固定。
固定的方式可以是通过点胶的方式进行固定。也可以是其他固定方式。
明显地，锦丝线511指的是从音圈51引出的导线外包覆了一层丝线，以增加强度。而在定心支片6上进行的2次固定则能够减小锦丝线511的振动幅度，以避免在振动过程中断裂。
在一个实施例中，如图2所示，所述定心支片6上还包括第三固定部61，所述第三固定部61位于与所述外壳1的第二连接点处，所述第三固定部61与所述第二固定部623之间设置有多个第一弹臂64，多个所述第一弹臂64靠近所述定心支片6边缘，相邻的两个第一弹臂64间形成有第一窗口65；所述信号接入端子9注塑在所述外壳1的对应所述第一窗口65处的位置。
在该实施例中，第三固定部61在装配时，与外壳1的边缘固定。第三固定部61和第二固定部623间形成间隙，在间隙内分布有多个第一弹臂64,以及相邻第一弹臂64间形成的第一窗口65。其中，形成的第一弹臂64和第一窗口65是围绕定心支片6的中心呈中心对称且分布均匀的。这样能使各第一弹臂64在振动过程中受力均匀，使定心支片6的振动更平稳。
在一个实施例中，所述第一固定部622与所述第二固定部623之间设置有多个第三弹臂，多个所述第三弹臂之间形成第三窗口621，其中，第三弹臂连接在第一固定部622的一端不超过筒状部63的底部；所述锦丝线511与所述第一固定部622固定后，继续经由所述第三窗口621延伸至所述第二固定部623，固定后再经由第一窗口64与所述信号接入端子9电连接。
在该实施例中，第一固定部622和第二固定部623之间的形成的第三弹臂作为支撑，相邻的第三弹臂间形成的第三窗口621用以将从过线部22引出的锦丝线511引出，经过第三窗口621后从第一窗口64穿出与信号接入端子9电连接。
这样的结构能够使锦丝线511直接穿过定心支片6，而不需要绕过定心支片6。减少了锦丝线511绕过定心支片6时产生的结构厚度。
现有技术中，锦丝线是从侧壁的顶部绕过。锦丝线增加了结构的高度方向上的厚度，有使锦丝线产生较大弯折。容易被损坏。
在上述实施例中，锦丝线511从音圈51上引出，沿过线部22穿过U铁2。这样就能够避免锦丝线511需要从U铁2上部绕过去，减少了绕线的装配步骤，并且节省了绕线的厚度，以降低发声装置整体的高度。这时锦丝线511位于定心支片6的下方，接着锦丝线511从第三窗口621穿过，到达定心支片6的上方。最后从第一窗口653穿出，连接到信号接入端子9上，与外界电路连通。这样在实现锦丝线511外接到电路的同时，又节省了在外壳1在高度方向上为锦丝线511引出而单独提供的空间。再次降低了发声装置整体的高度。
在其他例子中，定心支片6上可以设置2个对称的第三窗口621，以使锦丝线511能够从两边引出。也可以是定心支片6上设置有多个第三窗口621，多个第三窗口621绕着定心支片6上的通孔均匀分布。这样能够方便在装配时锦丝线511从多个不同的位置引出。
在一个实施例中，如图2,5所示，筒状部63的顶部向内形成弯折，弯折后形成的面与振膜组件7进行固定。弯折后形成的面相对于直接固定，与振膜组件7贴合固定的面积更大，能够增加定心支片6的固定强度。
在一个实施例中，如图1所示，第一弹臂64沿第三固定部61向下弯曲，并相对于筒状部63和第三固定部61形成凹陷。凹陷的结构中，筒状部63的顶部与第三固定部61齐平。
在该实施例中，这样的结构能够配合外壳1的结构，以减少结构在高度方向上的尺寸。
在其他例子中，在外壳1相对于第一弹臂64的位置设置第二弹臂12， 在相邻的第二弹臂12间形成第二窗口13。第二窗口13既减轻了外壳1的重量，节省了材料。又能在装配时作为观察内部装配结构的观察口。方便装配。
例如，外壳1上设置有多个第二弹臂12，相邻的第二弹臂12间形成第二窗口13。其中，第一弹臂64和第二弹臂12的分布相同，第一窗口65和第二窗口13相通。
第二弹臂12是向下弯曲形成凹陷的，这样能够使定心支片6上的第一弹臂64和外壳1上的第二弹臂12间配合。既可以简化装配，又能够避免在结构上相抵挡增加装置的整体高度。
并且，在装配发声装置时，第一窗口64和第二窗口65能够作为观察口对内部结构的组装进行观察。以检查装配是否正确。
在一个实施例中，所述发声装置的最小厚度≤10mm。该发声装置由上述结构装配后，其整体厚度最薄可以做到≤10mm的，相比于现有技术中的发声装置厚度，有很大的降低。
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。
