具体实施方式
为了更好的理解本申请的技术方案，下面结合附图对本申请实施例进行详细描述。
应当明确，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
应当理解，本文中使用的术语“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
需要注意的是，本申请实施例所描述的“上”、“下”、“左”、“右”等方位词是以附图所示的角度来进行描述的，不应理解为对本申请实施例的限定。此外，在上下文中，还需要理解的是，当提到一个元件连接在另一个元件“上”或者“下”时，其不仅能够直接连接在另一个元件“上”或者“下”，也可以通过中间元件间接连接在另一个元件“上”或者“下”。
扬声器用于实现发声功能，其性能直接决定电子产品的声音质量，在电子产品轻薄的需求下，扬声器的体积也受到限制，当扬声器的厚度被限制时，扬声器主要依靠提升振膜的有效辐射面积(Sd)来提升音质，当前的扬声器通常采用单磁路(single magnetic circuit system)或者五磁路(five  magnetic circuit system)设计，在振膜有效辐射面积一定的情况下，单磁路会导致磁路转换效率(BL)低，多磁路设计会导致后腔泄气不畅导致声阻偏高，进而影响机械品质因数(Q值，Qms)附近的灵敏度发挥。
如图1和图2所示，本申请提供一种扬声器A，扬声器A包括振膜组件2和磁路组件1，振膜组件2包括至少两个音圈21，磁路组件1包括第一磁铁12和第二磁铁11，多个第一磁铁12环绕设置在第二磁铁11四周，相邻两个第一磁铁12之间具有泄气槽13，其中，音圈21设置在第二磁铁11和第一磁铁12之间，扬声器A包括至少两个磁路组件1，磁路组件1与音圈21对应设置，相邻两个磁路组件1共用同一个第一磁铁12，当音圈21相对于磁路组件1运动时，泄气槽13用于排气。
振膜组件2和磁路组件1连接，磁路组件1用于提供磁场，振膜组件2能够在磁场中振动发声，其中磁路组件1包括第一磁铁12和第二磁铁11，第一磁铁12可以是边磁铁，第二磁铁11可以是中心磁铁，边磁铁环绕于中心磁铁设置，相邻两个磁路组件1共用一个边磁铁，多个音圈21可以根据实际需求进行串联、并联或者串并联结合，音圈21分别设置在边磁铁和中心磁铁之间，当音圈21通电时，音圈21中会产生电流，从而产生磁场，音圈21在磁路组件1所产生的磁场中受力运动。当音圈21中的电流发声变化时，音圈21所产生的磁场也发生变化，这种变化可以是电流大小的变化或者电流方向的变化，音圈21从而来回振动，音圈21配合振膜组件2发出声音。
本申请实施例提供的磁路组件1为五磁路设计，能够提供较强的磁场，从而提升扬声器A的驱动力，其中第一磁铁12和第二磁体的具体尺寸可以根据实际需求来设置，相邻的第一磁铁12可以相互垂直设置围成矩形，第二磁铁11设置在矩形的中央，线圈也可以相应设置为矩形并设置在第一磁铁12和第二磁铁11之间。其中，音圈21在振动时会推动磁路组件1内部的空气，相邻两个第一磁铁12之间具有间隙形成泄气槽13，用于排出空气，第一磁铁12围成的矩形四角都能够形成泄气槽13，因此除了扬声器A的四角位置外，沿扬声器A的长度方向也具有泄气槽13，从而增加泄气槽13的面积，且能够从多个方向排气，提升了排气效率，从而提升扬声器A的Q值，且泄气槽13设置在磁路组件1的四角能够减小对磁场的影响，使磁路组件1能够提供足够强的磁场。
如图2所示，在一种可能的实施方式中，至少一个音圈21的尺寸与其余音圈21的尺寸不同。
可以设置至少一个音圈21的尺寸大于其他音圈21，当扬声器A设置多个音圈21时，尺寸较大的音圈21能够起到较好的支撑效果，缓解振膜组件2刚度不足导致的分割振动。当音圈21通电并在磁路组件1所产生的磁场中振动时，能够驱动振膜22振动发声，而振膜组件2并不是完全的刚体，例如振膜组件2中的振膜22，振膜22在运动时会发生形变，声波沿着音圈21与振膜22的连接处向四周转播，当声波被反射时从而与其他波形相互干涉，最终形成区域化的振动，导致振膜22在不同频率的声波下被分割成多个区域，分割振动会严重影响扬声器A的保真度。本申请实施例提供的方案中，通过将至少一个音圈21设置成与其余音圈21不同的尺寸，具体的，可以设置一个音圈21的尺寸大于其余音圈21的尺寸，从而提高对振膜组件2的支撑效果，减少分割振动对扬声器A的影响。
如图2所示，在一种可能的实施方式中，振膜组件2包括三个音圈21，各音圈21沿扬声器A的长度方向依次设置。沿扬声器A的长度方向，位于中间的音圈21的尺寸大于位于两侧的音圈21的尺寸。
沿扬声器A的长度方向，尺寸最大的音圈21设置在中间，尺寸较小的音圈21设置在其两侧，相较于设置多个相同大小的音圈21，本申请实施例中，尺寸最大的音圈21能够对振膜22起到良好的支撑作用，缓解振膜22中心区域刚度不足导致的分割振动，提高扬声器A的保真度。
如图1所示，在一种可能的实施方式中，第二磁铁11的尺寸与该磁路组件1对应的音圈21的尺寸成正比。
当多个音圈21的尺寸不相同时，第二磁铁11的尺寸根据音圈21的尺寸相应设置，第一磁铁12的设置位置也和音圈21的尺寸相匹配，从而使磁路组件1能够与音圈21良好配合，扬声器A有足够的驱动力。
如图3所示，在一种可能的实施方式中，扬声器A包括盆架组件5，盆架组件5沿扬声器A的周向设置，盆架组件5具有排气槽51，排气槽51沿扬声器A的长度方向设置在盆架组件5的内圈，可以设置在盆架罪案的内圈边缘位置，盆架组件5为金属材质。
扬声器A还包括盆架组件5，盆架组件5由盆架和环形华司一体设置，环绕设置在扬声器A的边缘，用于固定和安装磁路组件1以及减少磁力分散的作用，盆架组件5具有排气槽51，排气槽51沿扬声器 A的长度方向设置在盆架组件5内圈的边缘，且排气槽51向远离磁路组件1的方向凹陷，排气槽51设置在两个磁路组件1之间，具体可以设置在相邻两个边磁铁之间，对于磁场磁力的分散效果也较小，排气槽51能够增加排气效率，提升扬声器A的Q值。盆架组件5对于磁路组件1能够起到支撑作用，盆架组件5上设置有于磁路组件1相对应的开孔，当音圈21沿扬声器A的厚度方向运动时，盆架组件5能够减少其沿扬声器A长度和宽度方向的偏移，减小音圈21发生偏移与边华司和中心华司发生碰撞的可能。盆架组件5为金属材质，能够起到良好的导磁效果，并具有足够的强度，从而降低在装配时发生弯曲形变的可能性。
如图1所示，在一种可能的实施方式中，扬声器A包括骨架7，振膜组件2包括振膜22和球顶23，骨架7设置在盆架组件5和振膜22之间，球顶23设置在振膜22远离盆架组件5的一侧。
振膜22是扬声器A的声音辐射元器件，对于扬声器A的放声性能有很大的影响，由于振膜22需要对快速变化的信号做出快速反应，且需要承受高速运动时产生的空气压力，所以振膜22的质量要轻且有足够的强度，此外振膜22不能因为环境温度和湿度的变化发生较大形变，否则可能影响扬声器A的发声效果，振膜22的材质一般可以选择塑胶、金属以及复合材料等，振膜22的形状和结构可以根据磁路组件1的数量和位置设置，振膜22比较柔软，相对坚硬的球顶23用于支撑振膜22。其中骨架7用于调整音圈21的位置，从而改善BL的对称性，使振动更加线性，提升扬声器A的音质。具体的，骨架7可以根据音圈21具体的设置位置和沿扬声器A厚度方向的尺寸来设置骨架7的具体形状，从而实现调整音圈21位置的效果。
如图5和图6所示在一种可能的实施方式中，扬声器A包括电路板71和小膜9，电路板71和骨架7一体设置，小膜9位于音圈21远离振膜22的一侧，并与音圈21连接。
电路板71用于电连接音圈21，从而使音圈21通电，电路板71可以是柔性电路板(FPC，Flexible Printed Circuit)，电路板71兼顾骨架7的作用，能够节约物料成本，且电路板71和骨架7一体设置能够减小电路板71对扬声器A内部空间的占用，从而提高对扬声器A内部空间的利用率。小膜9设置在音圈21远离振膜22的一侧，并与盆架组件5连接，当音圈21在实际振动时，除了会沿扬声器A的厚度方向运动外，由于装配等实际因素的影响，音圈21还可能沿着扬声器A的长度方向和宽度方向运动，最终影响音质，而小膜9可以在音圈21振动时起到缓冲作用，从而抑制音圈21的非线性振动，使音圈21的运动更加线性，从而提高扬声器A的音质。
如图1和图4所示，在一种可能的实施方式中，扬声器A包括电路板71和小膜9，小膜9位于音圈21远离振膜22的一侧，电路板71位于小膜9远离音圈21的一侧，小膜9与电路板71连接。
本实施例提供的方案中，电路板71和骨架7分体设置，具体小膜9和电路板71可以设置在相邻两个第二磁铁11之间，提高空间利用率从而利于将音圈21设计为更大的尺寸，小膜9设置在音圈21远离振膜22的一侧，并与盆架组件5连接，小膜9用于抑制音圈21的滚振，使其振动更加线性，电路板71设置在小膜9远离音圈21振膜22的一侧，用于电连接音圈21。
如图7所示，在一种可能的实施方式中，扬声器A还包括轭铁6，轭铁6用于安装磁路组件1，轭铁6设置有避让部65，避让部65用于避让电路板71。
轭铁6用于定位安装磁路组件1，其中轭铁6设置有避让部65，用于避让于小膜9连接的电路板71，使其在扬声器A的厚度方向上有足够的设置空间，其中避让部65可以是在轭铁6与电路板71对应位置设置缺口或者凹陷。
如图7和图8所示，在一种可能的实施方式中，轭铁6包括第一轭铁61、第二轭铁62和第三轭铁63，第二轭铁62设置在第一轭铁61和第三轭铁63之间。
当扬声器A包括多个磁路组件1时，多个磁路组件1在安装时需要定位，多个磁路组件1可以先分别安装在第一轭铁61、第二轭铁62和第三轭铁63上，例如当扬声器A包括三个磁路组件1时，第一轭铁61和第三轭铁63可以分别安装定位一个磁路组件1，第二轭铁62安装定位一个磁路组件1，再将第一轭铁61、第二轭铁62和第三轭铁63相互连接，相较于直接在整个轭铁6上定位安装多个磁路组件1，这种分体式的轭铁6减少了每一部分的零件数量，所以减小了每一部分的定位难度，从而减小视觉定位组装的整体难度，更准确的控制磁间隙，缩短总的磁间隙公差链，缩短组装周期，提升组装精度和良品率。
如图7和图8所示，在一种可能的实施方式中，第一轭铁61、第二轭铁62和第三轭铁63设置有连接部64，其中第一轭铁61和第三轭铁63靠近第二轭铁62的一侧设置有连接部64，第二轭铁62的两侧均设置有连接部64。
连接部64便于第一轭铁61、第二轭铁62以及第三轭铁63相互定位连接，其中连接时可以采用粘接和焊接等连接方式。
在一种可能的实施方式中，连接部64呈阶梯状，连接部64能够相互定位连接。
连接部64可以设置为凸台，使多个连接部64能够相互搭接，便于先定位第一轭铁61和第三轭铁63，再安装两者之间的第二轭铁62，最终通过点胶粘接或者激光焊接等方式连接。在安装时，可以将第一轭铁61和第三轭铁63定位到预设位置，与振膜22完成定位安装，再将第二轭铁62与第一轭铁61和第三轭铁63同时定位，并将第二轭铁62的连接部64与第一轭铁61和第三轭铁63的连接部64连接，从而完成扬声器A的装配。
连接部64还可以设置为凸起部与凹槽的配合，例如第一轭铁61和第三轭铁63设置的侧壁设置有凸起部，第三轭铁63的侧壁设置有凹槽，凸起部的至少部分能够伸入凹槽，这样设计便于各部分之间的定位准确，再通过点胶或者焊接等方式连接，从而实现第一轭铁61、第二轭铁62和第三轭铁63的连接，分离式的磁路设置是一种提升工艺同心度控制，即提升定位准确性的特殊结构设计，多个磁路组件1会包括大量的磁间隙，本申请实施例提供的分离式磁路设计能够提高定位准确性，从而实现极多磁间隙场景下的组装良率，从而提高方案的可行性。
扬声器A在装配时，可以先将磁路组件1分别安装在第一轭铁61、第二轭铁62和第三轭铁63，再通过连接部64相互连接装配，然后再安装振膜22。在安装振膜22时可以借助辅助钢环进行安装，振膜22在安装时其至少部分需要覆盖盆架组件5的侧壁，且盆架组件5的侧壁设置有凹陷部，用于使盆架组件5被振膜22覆盖后侧壁保持平整，辅助钢环可以设置在盆架组件5的边缘，辅助钢环的高度可以与盆架组件5的侧壁的凹陷部的高度相同，由于凹陷部的凹陷深度很小，所以不便于定位安装，当振膜22在定位安装时，辅助钢环能够对振膜22起到定位支撑的作用，便于振膜22安装，振膜22安装完成后辅助钢环被取下。
如图8所示，在一种可能的实施方式中，轭铁6设置有避让结构66安装部用于安装避让结构66。
扬声器A需要通过导电件进行电连接，导电件可以设置在避让结构66所在的位置，避让结构66的数量和位置可以根据导电件的实际情况设置，而导电件的设置可以根据音圈21的串联和并联的连接方式来确定，避让结构66用于在轭铁6上留出位置安装导电件，导电件可以不相对于扬声器A表面凸起，使扬声器A的表面平整。导电件包括正负极导电pad，起到导通作用。
如图9所示，在一种可能的实施方式中，扬声器A包括支撑架8，支撑架8安装于轭铁6，支撑架8的侧壁设置有排气孔81，排气孔81与泄气槽13对应设置。
支撑架8可以一体成型，在支撑架8的与泄气槽13相对应的位置设置有排气孔81，从而便于泄气槽13排气，支撑架8可以根据实际需求设置，并实现全灌装方案，从而便于控制成本。
如图9所示，在一种可能的实施方式中，支撑架8设置有支撑部82，支撑部82与避让部65对应设置。
当电路板71和骨架7分体设计时，轭铁6设置有避让部65对电路板71进行避让，支撑架8的底部在对应位置设置有支撑部82，支撑部82能够与避让部65相互配合，保护扬声器A的内部结构。
如图1所示，在一种可能的实施方式中，扬声器A包括第一华司3和第二华司4，第一华司3设置于第二磁铁11，第二华司4设置于第一磁铁12。
第一华司3可以是中心华司，第二华司4可以是边华司，边华司和中心华司用于连接和固定边磁铁以及中心磁铁，还能起到导磁的效果，将中心磁铁和边磁铁的N极和S极通过回路集中到中心磁铁和边磁铁之间的间隙中，使间隙存在较强的磁场，从而使位于间隙中的音圈21能够受到较强磁场的作用。
如图10所示，本申请实施例提供一种电子设备B，电子设备B包括壳体和安装于所述壳体的扬声器A，且扬声器A为上述任一实施例所述的扬声器A。
本申请实施例提供一种扬声器A及电子设备B，扬声器A包括振膜组件2和磁路组件1，振膜组件2包括至少两个音圈21，磁路组件1包括第一磁铁12和第二磁铁11，第一磁铁12环绕设置在第二磁 铁11四周，相邻两个第一磁铁12之间具有泄气槽13，其中，音圈21设置在第二磁铁11和第一磁铁12之间，扬声器A包括至少两个磁路组件1，磁路组件1与音圈21对应设置，相邻两个磁路组件1共用同一个第一磁铁12，当音圈21相对于磁路组件1运动时，泄气槽13用于提高排气效率，用于解决扬声器A泄气不畅的问题，磁路转换效率低的问题。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
