具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例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获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数 据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的一种折叠屏设备、折叠屏设备的控制方法及装置进行详细地说明。
图1示出一种可折叠的电子设备的结构示意图，如图1所示，本申请实施例公开的一种可折叠的电子设备110，可以包括：第一壳体111、以及与第一壳体111转动连接的第二壳体112。
其中，如图1所示，在本申请实施例中，在所述第一壳体111上设置有第一扬声器131；在所述第二壳体112上设置有辅助磁性件132，在所述第一壳体111与所述第二壳体112处于扣合状态的情况下，所述第一扬声器131和所述辅助磁性件132相对；在分离所述第一壳体111与所述第二壳体112的过程中，例如，接收到展开第一壳体111与第二壳体112的操作命令分离电子设备110的第一壳体111和第二壳体112的过程中，所述第一扬声器131与所述辅助磁性件132相斥或第一扬声器131与辅助磁性件132之间的吸合力减小。
在本申请实施例提供的可折叠的电子设备中，第一壳体111与第二壳体112转动连接，例如，第一壳体111与第二壳体112的连接部分120可以为转轴。在第一壳体111与第二壳体112处于扣合状态的情况下，设置在第一壳体111上的第一扬声器131与设置在第二壳体112上的辅助磁性件132相对设置，第一扬声器131与辅助磁性件132相吸，使得第一壳体111与第二壳体112扣合。在分离第一壳体111与第二壳体112的过程中，即在打开第一壳体111与第二壳体112之间的扣合时，第一扬声器131与所述辅助磁性件132之间可以产生相斥的斥力，从而可以消弱或抵消第一扬声器131与辅助 磁性件132之间的吸力，使第一扬声器131与辅助磁性件132相斥或使第一扬声器131与辅助磁性件132之间的吸合力减小，以方便展开第一壳体111与第二壳体112。
在本申请实施例中，第一扬声器131可以设置在第一壳体111上远离第一壳体111与第二壳体112的连接部分120的区域，例如，在图1中，第一扬声器131设置在第一壳体111的与所述连接部分相对的边缘。
在本申请实施例的一个可能的实现方式中，如图1所示，第一扬声器131中设置有扬声器线圈1311。因此，在一个可能的实现方式中，在所述扬声器线圈1311接通第一电流的情况下，所述扬声器线圈1311与所述辅助磁性件132之间可以产生相斥的斥力，使扬声器线圈1311与辅助磁性件132相斥。根据安培定律，扬声器线圈1311在接通电流的情况下，将产生电磁场，通过控制第一电流的方向，可以使得该电磁场的方向与所述辅助磁性件132靠近所述第一扬声器131的一端产生的磁场方向相同，从而使得扬声器线圈1311与辅助磁性件132相斥。从而可以减小第一扬声器131与辅助磁性件132之间的吸力，方便用户打开扣合的第一壳体111和第二壳体112。
在一个可能的实现方式中，如图2、图3a和图3b所示，第一扬声器131可以包括永磁铁1312和设置在所述永磁铁1312侧面的第一隔磁片141。其中，第一隔磁片141上设置有导电通路151，在分离所述第一壳体111与所述第二壳体112的过程中，所述导电通路接通第二电流，所述第一隔磁片141产生与所述辅助磁性件132相斥的斥力，使第一隔磁片141与辅助磁性件132相斥。在该可能的实现方式中，当第一扬声器131正常工作时，第一隔磁片141的隔磁作用可以减少第一扬声器中的永磁铁1312对电子设备内部或外部的其它部件产生磁力影响，在分离电子设备110的第一壳体111和第二壳体112的过程中，在第一隔磁片141上设置的导电通路151接通第二电流，使导电通路可以产生螺旋磁场，在辅助磁性件132靠近第一扬声器131的位置，该螺旋磁场与第一扬声器131中的永磁铁1312产生的磁场相反，使第一隔磁 片141与辅助磁性件132相斥，从而可以消弱或抵消永磁铁1312对辅助磁性件132产生的吸力。
在本申请实施例中，隔磁片是可以改变磁场磁力线方向的物体。它具有非常强的吸引磁场的作用，例如，如果在磁铁的旁边放一个隔磁片，磁铁的磁力线会被吸引到隔磁片上，隔磁片以外的空间磁场强度减小。
在本申请实施例中，隔磁片可以为软磁材料，即可以吸引磁场中磁力线，使其它部分磁场变弱的材料。另外，本申请实施例中的隔磁片可以为导体，即第一隔磁片141本身可以形成一个导电通路，该导电通路中接通的第二电流的方向可以平行于永磁体1312的周向，从而可以在永磁体1312的位置产生与永磁体1312相反磁场。例如，第一隔磁片141可以为钢片。
在一个可能的实现方式中，第一隔磁片141可以为多个，如图3a所示，多个所述第一隔磁片141围绕在所述永磁铁1312的四周。多个所述第一隔磁片141之间通过绝缘材料161进行连接。各个所述第一隔磁片141的导电通路151的两端设置有第一电极1411和第二电极1412。多个所述导电通路151沿所述永磁铁1312的周向设置。也就是说，在该可能的实现方式中，多个第一隔磁片141设置在所述永磁铁1312的周围，从而可以减小永磁铁1312四周的空间磁场强度。多个所述第一隔磁片141上的导电通路151在导通第二电流时，可以产生与永磁铁1312相反的磁场。例如，假设在图3a中，永磁铁1312的下端面的磁场方向向上，则可以向多个第一隔磁片141的导电通路导通如图3b所示的第二电流，从而产生向下的磁场，从而可以使得第一隔磁片141与辅助磁性件132相斥，进而可以辅助展开第一壳体111和第二壳体112。
在一种可能的实现方式中，如图3a所示，任意两个相邻的第一隔磁片1411之间可以通过绝缘材料161进行粘接，该绝缘材料可以是塑胶，也可以是其它材料，本申请实施例对此不作具体限定，通过绝缘材料，使得每个第一隔磁片1411在通电时不会出现电流串扰到其它部分的情况。
在一种可能的实现方式中，如图4所示，第一扬声器131可以包括永磁铁1312和设置在所述永磁铁1312的目标侧的第二隔磁片1412，所述第二隔磁片142上设置有辅助线圈1421，在分离所述第一壳体111与所述第二壳体112的过程中，所述辅助线圈1421接通第三电流，在辅助磁性件132靠近第一扬声器131的一端，所述辅助线圈1421产生的磁场与所述永磁铁1312产生的磁场方向，使辅助线圈1421与辅助磁性件132相斥。其中，在所述第一壳体111与所述第二壳体112处于扣合状态的情况下，所述目标侧为所述第一扬声器131的远离所述第二壳体112的一侧。也就是说，第二隔磁片142设置在靠近第一壳体111外表面的一侧。当第一扬声器131正常工作时，第二隔磁片142的隔磁作用可以减少第一扬声器131中的永磁铁1312对其它部件产生磁力影响；当在分离电子设备110的第一壳体111和第二壳体112的过程中，第二隔磁片142上设置的辅助线圈1421接通第三电流，使辅助线圈1421可以产生磁场，在辅助磁性件132靠近第一扬声器131的一端，该磁场与第一扬声器131中的永磁铁1312产生的磁场相反，使第二隔磁片142与辅助磁性件132相斥，从而可以消弱或抵消永磁铁1312对辅助磁性件132产生的吸力。例如，假设在图4中，永磁铁1312的磁场方向向上，则可以向第二隔磁片142的辅助线圈1421导通如图4所示的第三电流，从而产生向下的磁场(如图4中的箭头所示)，即与所述辅助磁性件132相斥，进而可以辅助展开第一壳体111和第二壳体112。
在本申请实施例的一个可能的实现方式中，可以在第一扬声器131上同时设置多个第一隔磁片141和第二隔磁片142。如图5所示，多个所述第一隔磁片141设置在所述永磁铁1312周围，围成一个腔体171。所述永磁铁1312设置在所述腔体171内；所述第二隔磁片142设置在所述腔体171的一个端面。在所述第一壳体111与所述第二壳体112处于扣合状态的情况下，第二隔磁片142位于所述腔体远离所述第二壳体112的一侧。第二隔磁片142上设置有辅助线圈1421。第一隔磁片141和第二隔磁片142可以包裹住永磁铁 1312，降低永磁铁1312各个面产生的磁场对外部其它磁性器件的干扰，并且可以在展开第一壳体111与所述第二壳体112时，减小第一扬声器131与辅助磁性件132之间的吸合力。例如，若隔磁片与辅助磁性件之间的斥力大于第一扬声器131的永磁铁与辅助磁性件132之间的吸合力，使得第一扬声器131与辅助磁性件132相斥，从而使第一壳体111与所述第二壳体112之间出现缝隙，用户使用单手即可轻松分离第一壳体111与所述第二壳体112。
在本申请实施例的一个可能的实现方式中，如图6所示，辅助磁性件132可以包括第二扬声器133，第二扬声器133的结构与所述第一扬声器141的结构相同。也就是说，辅助磁性件132可以为与第一扬声器131的结构相同的扬声器。通过该可能的实现方式，可以利用电子设备中相对设置的两个扬声器中的永磁铁之间的吸合力实现第一壳体111与第二壳体112之间的扣合，并在用户需要打开电子设备，即用户需要分离(或者也可以称为打开)第一壳体111和第二壳体112时，通过向各个扬声器接通相应的电流，使相对设置的两个扬声器之间互斥或者使两个扬声器之间的吸合力减小，从而使用户能够更为轻松的展开或分离第一壳体111与第二壳体112。
在一个或多个可能的实现方式中，在第一扬声器131和第二扬声器133的相对端，所述第一扬声器131中的永磁铁与所述第二扬声器133中的永磁铁的磁性相反。也就是说，在第一壳体111与第二壳体112的扣合状态，第一扬声器131与第二扬声器132相吸。
在一个或多个可能的实现方式中，在分离所述第一壳体111与所述第二壳体112时，所述第二扬声器133与所述第一扬声器131之间产生相斥的斥力，使第二扬声器133与第一扬声器132相斥或第二扬声器133与第一扬声器132之间的吸合力减小。例如，与上述第一扬声器131类似，可以向第二扬声器133的扬声器线圈接通第一电流，使得所述第二扬声器133的扬声器线圈与所述第一扬声器之间产生相斥的斥力。或者，向第二扬声器133的第一隔磁片141接通第二电流，使得所述第二扬声器133的第一隔磁片141与 所述第一扬声器之间产生相斥的斥力。又或者，向第二扬声器133的第二隔磁片142接通第三电流，使得所述第二扬声器133的第二隔磁片142与所述第一扬声器之间产生相斥的斥力。
在一个可能的实现方式中，如图6所示，所述第一壳体111上设置有多个所述第一扬声器131，多个所述第一扬声器131均匀分布在所述第一壳体111远离所述连接部分120的边缘；所述第二壳体112上对应多个所述第一扬声器131设置有多个所述辅助磁性件132，多个所述辅助磁性件132均匀分布在所述第二壳体112远离所述连接部分120的边缘。通过多个第一扬声器131和多个辅助磁性件132可以保证所述第一壳体111与第二壳体112之间扣合紧密。
在一个或多个可能的实现方式中，第一壳体111上相邻的两个所述第一扬声器112的永磁铁相互靠近的一端磁性相反。从而可以使得电子设备整机的磁场可以抵消，尽可能降低对外部其他磁性器件的干扰。
在一个可能的实现方式中，第一扬声器131可以包括：永磁铁1312、扬声器线圈1311、多个第一隔磁片141、和第二隔磁片142；多个所述第一隔磁片141设置在所述永磁铁1312周围，围成一个腔体171，所述永磁铁1312设置在所述腔体171内；所述第二隔磁片142设置在所述腔体171的一个端面，在所述第一壳体111与所述第二壳体112处于扣合状态的情况下，第二隔磁片142位于所述腔体171远离所述第二壳体112的一侧；第二隔磁片142上设置有辅助线圈1421；在所述第一壳体111与所述第二壳体112处于扣合状态时，所述永磁铁1312与所述辅助磁性件132之间具有相吸的第一吸力；在分离所述第一壳体111与所述第二壳体112的过程中，所述永磁铁1312与所述辅助磁性件132之间具有相吸的第一吸力，所述扬声器线圈1311与所述辅助磁性件132之间具有相斥的第一斥力，多个所述第一隔磁片141与所述辅助磁性件132之间具有相斥的第二斥力，所述第二隔磁片142与所述辅助磁性件132之间具有相斥的第三斥力，所述第一斥力、第二斥力与所述第三 斥力的合力大于所述第一吸力。
通过该可能的实现方式中，在分离所述第一壳体111与所述第二壳体112的过程中，例如，接收到外部输入的展开所述第一壳体111与所述第二壳体112时，第一扬声器131的扬声器线圈1311、多个所述第一隔磁片141和所述第二隔磁片142与所述辅助磁性件132之间均具有相斥的斥力，所述第一斥力、第二斥力与所述第三斥力的合力大于所述第一吸力，从而使得所述第一壳体111与所述第二壳体112之间可以产生缝隙，方便展开所述第一壳体111与所述第二壳体112。
在一个可能的实现方式中，在所述电子设备处于跌落状态时，所述第一扬声器131与所述辅助磁性件132之间具有相吸的第二吸力；其中，所述第二吸力包括所述第一吸力，且所述第二吸力还包括以下至少之一：

例如，所述电子设备中可以设置传感器，通过传感器可以检测电子设备的运动状态，在根据传感器检测到的运动状态，确定电子设备处于跌落状态的情况下，可以控制扬声器线圈1311接通与第一电流方向相反的电流，从而使得扬声器线圈1311与所述辅助磁性件132之间具有相吸的第三吸力。还可以控制多个第一隔磁片141接通与第二电流相反的电流，从而使得多个所述第一隔磁片141与所述辅助磁性件132之间具有相吸的第四吸力。还可以控制第二隔磁片142接通与第三电流方向相反的电流，使得所述第二隔磁片142与所述辅助磁性件132之间具有相吸的第五吸力。
通过上述可能的实现方式，可以在扣合状态下整机跌落时提前识别并增强异性磁场强度，使第一壳体111与第二壳体112以强吸力牢牢扣合，保证电子设备跌落不会把第一壳体111与第二壳体112摔开造成其他更严重问题，
在上述可能的实现方式中，传感器可以是重力传感器，也可以是陀螺仪， 本申请实施例对此不作具体限制。
下面以电子设备为图6所示的电子设备为例对本申请实施例提供的电子设备进行说明。
在该实施例中，第一扬声器131和第二扬声器133为扬声器开关模组，如图6所示，电子设备左右机身边缘分别对称放置4个扬声器开关模组，每个扬声器开关模组可以包括如图7所示的扬声器结构。
如图7所示，每个扬声器内部包含一个可动的导线缠绕而成的扬声器线圈1311，同时包含4个辅助磁铁13121和一个主磁体13122，4个辅助磁铁13121和一个主磁体13122共同组成永磁铁1312，在永磁铁1312的一个端面，中心最大的主磁铁13122向上呈现N级，四周一圈辅助磁铁13121呈现S级，在远离永磁铁1312的位置以及正对永磁铁1312中心的条件下观测，永磁铁1312的该端面整体会呈现中心磁铁的N级特性，仅当贴近永磁铁1312边缘时才能观测到永磁铁1312呈现S级特性。
在本申请实施例中，可以利用扬声器自身特性，电子设备的左右机身(即上述的第一壳体111和第二壳体112)放置的每一对位置对称的扬声器开关模组采用相反的装配方向，这样扣合状态下，不考虑线圈通电的状态，两个扬声器会由于自身永磁铁的磁场呈现异性而产生吸力。考虑到永磁铁可能对外部环境中的磁性物质产生吸引(如铁屑、铁螺钉等)，如图8所示，每个扬声器还可以设置隔磁片对扬声器进行5面隔磁片包裹设计，仅保留折叠方向开口设计。
例如，第一壳体上设置4个第一扬声器131，每个第一扬声器131包裹一个隔磁片组，一个隔磁片组可以包括4个第一隔磁片141和一个第二隔磁片142，第二壳体上设置4个第二扬声器132，每个第二扬声器133包裹一个隔磁片组，一个隔磁片组可以包括4个第一隔磁片141和一个第二隔磁片142。
如图8所示，当整机关机或待机状态下，利用第一扬声器131与第二扬声器133自身永磁铁吸力实现了扣合作用，而整机外侧加装第二隔磁片142 及侧边加装第一隔磁片141，将第一扬声器131和第二扬声器133的磁场束缚在一定区域内，避免磁场影响范围过大影响到整机外部的物体及整机内部其他磁性敏感器件。
根据安培定则(即右手螺旋定则)，通电导线产生磁场，磁场的方向遵循右手拇指指向；根据此定则针对性设计一个扬声器(包括第一扬声器131和第二扬声器133)的隔磁片如下：
1、包裹扬声器的5面的4个第一隔磁片141和一个第二隔磁片142，各个隔磁片在接缝处进行绝缘，即五面独立设计，彼此互不影响，单个隔磁片通电不会导致电流串扰到其他部分；
2、侧边的第一隔磁片141内部为一条平直的导线通路，第一隔磁片141左右两侧分别为通电的电极，其中，电极本身无正负之分，通过驱动端正负变换来控制第一隔磁片141内部电流流向。并且，该电极可以为电镀电极，以防止氧化；
3、顶部的第二隔磁片142内部为一根导线环绕而成的线圈，表面同样裸露导线的开始和结束端作为电极。
在第一隔磁片141和第二隔磁片142中针对性的施加不同方向电流，根据安培定则可知，通过控制第一隔磁片141和第二隔磁片142以及扬声器内部的扬声器线圈1311通入电流的大小和方向，叠加扬声器(包括第一扬声器131和第二扬声器133)本身的永磁铁磁场，即可实现控制整机的扣合吸力动态变化，实现第一扬声器131和第二扬声器133从异性相吸变为同性相斥，这样即可让第一壳体111和第二壳体112从扣合状态自动弹开一个角度，从而方便的让用户单手进行打开操作。
下面对第一壳体111和第二壳体112从扣合状态到展开状态的过程中的磁场变化进行说明。
当整机不做任何操作时，将折叠屏进行扣合，在扣合之后第一壳体111和第二壳体112对应的第一扬声器131和第二扬声器133接近贴合状态，图 8示出第一扬声器131和第二扬声器133相对面的磁性，如图8所示，由于每一对第一扬声器131和第二扬声器133装配方向均相反，即第一扬声器131和第二扬声器133相对装配，因此扣合之后彼此总磁场呈现异性相吸，从而将整机锁定在扣合状态不动。
在第一壳体111与第二壳体112的扣合状态下，用户如果需要实现整机自动打开角度，可以输入一个打开的操作命令。具体地，可以通过电子设备的输入装置输入该操作命令，该输入装置可以是物理按键或键盘，例如，设置在电子设备上的按键，也可以是语音接收装置，例如，麦克风，该输入装置还可以为电子设备的显示屏。例如，在扣合后，用户可以在电子设备的副显示屏(例如，该副显示屏可以设置在第一壳体111的外表面)上进行操作：首先唤醒副屏，此时副屏会出现提示自动打开的滑块，将滑块滑动至末端即输入上述操作指令，触发自动打开操作。
在接收到自动打开操作后，系统内部输出电流至第一扬声器131和第二扬声器133内部的线圈及外部隔磁片，使整机8个扬声器磁场变化为同性相斥，具体过程如图9所示。
如图9所示，在整机处于初始状态时，即第一壳体111和第二壳体112处于扣合状态的情况下，此时无电流，第一壳体111上的第一扬声器141的磁场的极性为S极，第二壳体112上的第二扬声器142的磁场的极性为N极，整机依靠第一扬声器131和第二扬声器133自身永磁铁吸力吸附。
在第一扬声器131和第二扬声器133的扬声器线圈1311通电的情况下，第一壳体111上的第一扬声器141通电产生与自身永磁铁磁力相反的磁场，第一壳体111上的第一扬声器141的整体磁性下降，第二壳体112上的第二扬声器142通电产生与自身永磁铁磁力相同的磁场，此时，第二壳体112上的第二扬声器142的整体磁性增强，此时总磁场基本不变，扣合总吸力变化不大；当第一扬声器131和第二扬声器133上的第一隔磁片141和第二隔磁片142进一步通电时，第一扬声器131上的第一隔磁片141和第二隔磁片142 产生的磁场直接将弱化磁力后的第一扬声器131的磁场特性反向。第一扬声器131上的总磁场呈现的极性为N极，第二扬声器133的第一隔磁片141和第二隔磁片142则进一步增强第二扬声器133的总磁场大小，第二扬声器133的总磁场呈现的极性也仍然为N极，从而可以实现上下同性相斥的状态，从而使整机被互斥力作用而打开角度。
在整机打开一定角度的过程中，由于第一扬声器131和第二扬声器133之间的距离增大，磁场随距离呈指数降低，第一扬声器131和第二扬声器133之间的扣合总吸力迅速减小，吸力减小至0后，整机由于惯性再打开一点距离。在扣合动作触发结束之后(即整体打开状态下)，第一隔磁片141和第二隔磁片142和扬声器线圈1311停止通电，此时第一扬声器131和第二扬声器133恢复初始状态，呈现大小相同极性相反的磁场，而由于整机已经打开一定角度，对称的第一扬声器131和第二扬声器133距离过远，此时扣合吸力可忽略不计，因此整机不会再扣合回去，而转轴中的阻尼会让折叠设备停在自动打开后的角度，用户可以轻松使用单手将打开角度后的整机展开。
