下面结合附图，对本申请的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
如图1至图7所示，根据本申请的第一方面，本申请实施例提供了一种扬声器，包括振动系统、磁路系统40和具有收容腔的盆架10，磁路系统40设置在收容腔111内。其中，振动系统包括振膜20和用于驱动振膜20振动发声的音圈30，振膜20包括设有防水透气膜22、具有孔结构231的球顶23和设有通孔211的音膜21，通孔211与孔结构231的数量相同。
在本实施方式中，音膜21设置在收容腔111内以将收容腔111分隔为前音室和后音室，前音室即为音膜21背对磁路系统40的空间，后音室即为音膜21朝向磁路系统40的空间，球顶23和音圈30设在后音室中，通孔211与孔结构231连通，使得前音室和后音室之间通过孔结构231及通孔211连通，其中，防水透气膜22设置在音膜21背对球顶23的一侧并对应覆盖在通孔211上，起到防水作用，同时又可以增大振膜20的透气量，有效提高了扬声器的音质。
在一个可选的实施方式中，磁路系统40包括磁轭、固定于磁轭上的主磁钢以及分别间隔设置于主磁钢相对两侧并与主磁钢形成磁间隙的副磁钢，音圈30插设于磁间隙中，使得音圈43能够在主磁钢32的磁感应作用下振动并带动振膜41振动发声。
其中，前音室与后音室之间由于音膜21的振动而产生压差，从而可以通过孔结构231及通孔211使得上腔与下腔之间形成流动的气流，降低了前音室与后音室之间的压差值，即减小了音膜21在振动过程中受到的压差阻力，有效提高了扬声器的音质，使得扬声器在使用时声音效果较好，能满足较高的要求。
由于防水透气膜设置在音膜21背对球顶23的一侧，且防水透气膜的位置与通孔211及孔结构231的位置相对应，不仅能够起到防水作用，同时也增大振动系统的透气量，提高了扬声器的音质和立体声效果。
在一个可选的实施方式中，孔结构231沿球顶23的宽度方向阵列排布成两排或两排以上，通孔211的位置与孔结构231的位置相对应，使得前音室能够通过每一个孔结构231及通孔211与后音室连通，从而可以增大振动系统的透气量。
在一个可选的实施方式中，孔结构231排布成两排，两排孔结构231对称设置在球顶23在宽度方向的中心轴的两侧，避免了本申请中的扬声器在工作时其振动系统发生不平衡振动，从而提高了扬声器的稳定性，而且可以将扬声器的功率做更大也不会发生不平稳振动，使本申请的扬声器的声学性能更优。
在一个可选的实施方式中，孔结构231的直径与通孔211的直径相等，使得位于后音室的球顶23上的每个孔结构231能够通孔211连通前音室，确保振膜20的透气量，即保证了前音室与后音室之间的气流能够通过透气孔231及通孔211形成的通道来回流动。
在一个可选的实施方式中，孔结构231或通孔211的直径为0.1～0.3mm；和/或，每一排孔结构231或通孔211的数量为12个，以满足扬声器在振动发声过程中对音膜21的性能要求。其中，孔结构231或通孔211的直径及数量还可以等于其他的取值，具体可以根据音膜21的宽度、长度及音膜21的性能要求而设定。
在一个可选的实施方式中，音膜21设有自球顶23连接的表面向远离球顶23的方向凹陷形成折环部214，通孔211设置在折环部214内侧的安装部212上，这样能够更迅速地响应后音室中空气的振动，从而提高了扬声器的低音品质。
其中，音膜21包括固定部213、安装部212和上述的折环部214，安装部212通过折环部214与固定部213连接，固定部与盆架10固定连接。其中，球顶23贴附在音膜21的安装部上。
在一个可选的实施方式中，防水透气膜22通过粘接层221粘贴在安装部212的通孔211处。
在一个可选的实施方式中，盆架10包括具有上述收纳空间的底框11和盖合在收纳空间开口处的顶盖12，音膜21通过固定部213固定在顶盖12与顶盖12的连接处，使得底框11、顶盖12以及音膜21能够围合形成一个密封的空间，保证密封性。
在一个可选的实施方式中，音膜21的制作材料包括硅胶、橡胶、PEEK、TPU及其他高分子材料，防水透气膜包括依次贴复合连接的织物层、粘接层及防水透气层。其中，防水透气层优选为经过双向拉伸处理后的膨胀聚四氟乙烯微孔薄膜层，在双向拉伸过程中无机填料微粒与正在定型的塑料膜基体结合处形成微孔，由于这些微孔的尺寸为亚纳米级，微孔孔径可以在0.05~15μm之间，便于气流能够通过微孔来回流动，而且微孔的孔径尺寸不足以让水分子通过，起到防水效果，不仅避免了水分通过微孔进入下腔，同时也防止灰尘或金属粉末通过微孔进入下腔而影响扬声器的声音质量。
综上所述：在该扬声器运行而发声的过程中，音圈30在变化电流以及磁路系统40的共同作用下，音圈30带动音膜21振动，从而使音膜21附近的空气振动而发声，并且在音膜21振动的过程中，被音膜21隔离开的前音室和后音室之间。由于音膜21的振动而产生压差，对扬声器的性能造成影响。因此，本申请将球顶23和防水透气膜22分开设置在音膜21的上下两侧，能够保证音膜21的增大透气量，确保前音室和后音室之间的气流能够通过孔结构及通孔来回流动，降低了前音室和后音室之间的压差值，即减小了音膜21在振动过程中受到的阻力，从而得以提高音质和立体声效果。此外，由于防水透气膜22设置在通孔处上，能够起到防水作用。
如图1至图7所示，根据本申请的第二方面，本申请还提供一种电子设备，包括上述的扬声器。
