 本发明的实施方式
下面结合附图和实施方式对本发明作进一步说明。
参阅图1、图2和图4所示（也可参阅图7和图8），在一个实施例中，一种扬声器，包括：安装壳体300以及收容于所述安装壳体300内的振动系统400及驱动所述振动系统400振动发声且具有磁间隙600的磁路系统500，所述安装壳体300的上壳体310盖设在所述磁路系统500上，所述上壳体310朝向所述磁路系统500的一面设有第一连接部100，所述磁路系统500朝向所述上壳体的一面设有第二连接部200，所述第一连接部100与所述第二连接部200固定配合。
上述扬声器在使用时，可以先将第一连接部100装设在上壳体310上，将第二连接部200装设在磁路系统500朝向上壳体310的一面。当上壳体310与磁路系统500盖设配合后，第一连接部100与第二连接部200连接配合。在第一连接部100与第二连接部200连接配合时，第一连接部100与第二连接部200可以通过激光焊点进行连接固定、第一连接部100与第二连接部200通过胶黏剂进行粘接固定、第一连接部100与第二连接部200卡接固定等。进一步地，第一连接部100可以是通过对上壳体310的内表面进行打薄处理得到，第二连接部200可以通过对磁路系统500朝向上壳体310的一面进行打薄处理得到。或者，第一连接部100与第二连接部200可以是独立部件，即第一连接部100可以通过焊接或粘接的方式装设在上壳体310的特定位置，第二连接部200可以通过焊接或粘接的方式装设在磁路系统500的特定位置上。扬声器通过第一连接部100与第二连接部200实现固定配合，使得上壳体310与磁路系统500实现了连接配合，当扬声器进行发声时，上壳体310能够与磁路系统500同步动作，从而有效较低了上壳体310的壳振。同时，在扬声器受到外力影响时，通过第一连接部100与第二连接部200的固定配合，也能够有效保证安装壳体300内部部件（例如：磁路系统500与振动系统400等）的可靠稳定性。
参阅图2和图3，在一个实施例中，所述第一连接部100朝向所述磁路系统500的方向凸出设置，所述第二连接部200朝向所述上壳体310的方向凸出设置，所述第一连接部100与所述第二连接部200焊接。所述上壳体310上沿上壳体310的长度方向间隔设有两个所述第一连接部100，所述磁路系统500上对应设有两个所述第二连接部200，所述第一连接部100与所述第二连接部200上下对应连接，并且在所述上壳体310与所述磁路系统500之间围设形成出音通道501。具体地，上述这种实施方式使得安装壳体300内部产生振动声波可以直接经过出音通道501导出，即能够避免振动声波在安装壳体300内部传播过程中的失真现象，保证了振动声波在传出时的高频性能。
在一个实施例中，所述第一连接部100与所述磁路系统500的一面组装成型，所述第二连接部200与所述安装壳体300的上壳体310组装成型，或所述第一连接部100与所述磁路系统500的一面一体成型，所述第二连接部200与所述安装壳体300的上壳体310一体成型。具体地，第一连接部100与第二连接部200为板体或块体。第一连接部100可以是通过对上壳体310的内表面进行打薄处理得到，第二连接部200可以通过对磁路系统500朝向上壳体310的一面进行打薄处理得到。或者，第一连接部100与第二连接部200可以是独立部件，即第一连接部100通过焊接或粘接的方式装设在上壳体310的特定位置，第二连接部200可以通过焊接或粘接的方式装设在磁路系统500的特定位置上。进一步地，在本实施例中，第一连接部100为两个，两个第一连接部100间隔装设在上壳体310上。第二连接部200为两个，两个第二连接部200间隔装设在磁路系统500上，即两个第一连接部100与两个第二连接部200对应连接固定。上述这种实施方式能够更加有效的保证上壳体310与磁路系统500之间的连接效果。
参阅图2至图4，在一个实施例中，所述安装壳体300还包括下壳体320与盆架330，所述上壳体310与所述下壳体320配合形成装配腔340，所述盆架330固持于所述上壳体310与所述下壳体320之间，所述振动系统400与所述磁路系统500位于所述装配腔340中，且所述振动系统400与所述磁路系统500均收容于所述盆架330上。具体地，上壳体310与下壳体320在拼装时通过盆架330进行对位拼接，从而能够使得安装壳体300的对位安装更加准确。另外，在上壳体310与下壳体320固定后，盆架330位于装配腔340内部，此时盆架330可以为振动系统400的安装提供辅助支撑或辅助定位，即使得振动系统400能够更加稳定地在装配腔340中固定。
参阅图2至图4，在一个实施例中，所述磁路系统500包括磁碗件510、磁感组件520及固持于所述下壳体320的磁轭530，所述磁感组件520固持于所述磁轭530上，所述磁碗件510罩设在所述磁感组件520上，所述磁碗件510上远离所述磁感组件520的表面设有所述第二连接部200。具体地，通过对上壳体310的内侧面（指与磁碗件510相对应的内侧面）进行局部打薄，即在上壳体310上形成了第一连接部100。以及通过对磁碗件510的端面（指与上壳体310内侧面相对应的端面）进行局部打薄，即在磁碗件510上形成了第二连接部200，根据上壳体310与磁碗件510的自身强度或自身体积大小，可以在上壳体310上打薄形成多个第一连接部100以及在磁碗件510上打薄形成多个第二连接部200。
参阅图2至图4，在一个实施例中，所述磁感组件520包括固设于所述磁轭530上的主磁钢521和围绕所述主磁钢521设置的副磁钢522，所述主磁钢521与所述副磁钢522间隔设置形成所述磁间隙600，所述磁碗件510罩设在所述主磁钢521上，且所述磁碗件510的周向侧壁均与所述副磁钢522贴合抵触。可选地，可以在磁轭530上加设加强筋，以增强磁轭530的强度，从而可以有效地防止跌落中出现因磁轭530形变导致的磁路系统500凹陷的问题。进一步地，沿磁碗件510的周向在磁碗件510上间隔设有用于与副磁钢522抵触贴合的多个抵触部511，抵触部511包括连接板5111与抵触板5112，连接板5111的其中一端与磁碗件510相连，连接板5111的另一端与抵触板5112相连，抵触板5112的板面用于与副磁钢522朝向抵触板5112的一面贴合抵触。
参阅图2至图4，在一个实施例中，所述振动系统400包括发声振膜410、支撑振膜420、音圈430与音圈支架440，所述音圈430套设在所述主磁钢521外周且所述音圈430位于所述磁间隙600中，所述音圈430固设于所述音圈支架440上，所述发声振膜410套设在所述磁碗件510的外周，所述发声振膜410与所述音圈支架440的其中一端面贴合抵触，所述支撑振膜420与所述音圈支架440远离所述发声振膜410的端面贴合抵触。具体地，音圈支架440套设在磁碗件510的外部，然后连接部伸入磁间隙600中，并实现连接部与音圈430的贴合抵触。发声振膜410套设在磁碗件510的外部，支撑振膜420固设于盆架330中。盆架330能够固设在上壳体310与下壳体320之间，因此，发声振膜410与支撑振膜420可以借助盆架330在安装壳体300内部实现辅助固定。进一步地，在通电情况下，音圈430首先在磁间隙600中进行振动，同时音圈430能够带动音圈支架440同步振动，音圈支架440会带动发声振膜410与支撑振膜420进行同步振动，即发声振膜410发出振动声波，支撑振膜420对音圈支架440的振动起到支撑缓冲的作用，同时在支撑振膜420的限制下，也能够更加有效的保证音圈支架440按照预设方向进行振动，即避免声音出现失真。
参阅图5和图6，在一个实施例中，所述音圈支架440上设有用于与所述音圈430连接配合的贴合部441，所述贴合部441包括第一贴合板4411与第二贴合板4412，所述第一贴合板4411装设在所述音圈支架440上，所述第二贴合板4412装设在所述第一贴合板4411上，所述第一贴合板4411与所述第二贴合板4412呈夹角设置，所述第一贴合板4411用于与所述音圈430的侧面相贴合，所述第二贴合板4412与所述音圈430的端面相贴合。具体地，通过第一贴合板4411与第二贴合板4412对音圈430相邻的两个面进行贴合抵触。同时，根据音圈430的自身形状，确定第一贴合板4411与第二贴合板4412的夹角度数。因此，上述这种实施方式能够有效保证第一贴合板4411与第二贴合板4412与音圈430充分的贴合抵触。
参阅图2至图4，在一个实施例中，所述发声振膜410包括连接环411、振动内膜412与振动外膜413，所述振动内膜412套设在所述磁碗件510的外周，所述振动外膜413套设在所述振动内膜412的外周且与所述振动内膜412间隔设置，所述连接环411的其中一面连接所述振动内膜412与振动外膜413，所述音圈支架440与所述连接环411远离所述振动内膜412与所述振动外膜413的一面贴合抵触。具体地，通过连接环411对振动内膜412与振动外膜413进行拼接，例如：振动内膜412与振动外膜413能均与连接环411胶黏粘接。同时，根据安装需要连接环411与音圈支架440也可以胶黏粘接。音圈支架440在带动连接环411进行振动时，连接环411能够保证振动内膜412与振动外膜413同步振动，即保证了扬声器的出声效果。这仅仅是其中一种实施方式，例如：根据实际情况，发声振膜410可以采用单膜结构，即仅利用一个振膜与音圈支架440进行抵触，并随音圈支架440的振动进行发声。
参阅图2至图4，在一个实施例中，所述振动系统400还包括限位骨架460，所述限位骨架460套设在所述磁碗件510的外部，所述限位骨架460位于所述振动内膜412与所述磁碗件510之间，且所述限位骨架460与所述振动内膜412相抵触。具体地，考虑到振动内膜412套设在磁碗件510的外部后，振动内膜412与磁碗件510之间会留有安装间隙，将限位骨架460套设在磁碗件510上，使得限位骨架460能够填充该安装间隙。即振动内膜412在振动时与限位骨架460保持抵触，有效保证了振动内膜412在振动时的同心度。
参阅图2至图4，在一个实施例中，所述振动系统400还包括柔性电路板450，所述支撑振膜420包括辅助安装板421与缓冲振膜422，所述柔性电路板450与所述音圈430电性连接，所述柔性电路板450通过所述辅助安装板421固设于所述盆架330中，且所述柔性电路板450与所述音圈支架440远离所述发声振膜410的端面贴合抵触，所述缓冲振膜422与所述柔性电路板450背离所述辅助安装板421的一面连接。具体地，通过柔性电路板450为音圈430进行供电。通过柔性电路板450与缓冲振膜422的协同配合能够对音圈支架440的振动起到更加有效的缓冲效果。同时，通过辅助安装板421对柔性电路板450进行辅助固定，使得柔性电路板450在安装壳体300内部的安装更加稳固。
