具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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他实施例，都属于本公开保护的范围。
如图1所示，本公开还提供一个实施例的终端设备100，包括：包括壳体101、信号处理单元102、声波信号发声单元103以及N个振动膜片阵列104，任意一个振动膜片阵列104包括至少两个振动膜片1041，信号处理单元102与声波信号发声单元103连接，N个振动膜片阵列104分别置于壳体101的不同位置处，其中，N为大于或等于2的整数。其中，信号处理单元103根据接收的初始电信号生成M个振动控制电信号，信号处理单元103将生成的M各振动控制信号传递给声波信号发生单元130，声波信号发声单元103用于根据信号处理单元102传递的M个振动控制电信号生成M个声波信号，并输出M个声波信号，其中，M个声波信号的频率分别与N个振动膜片阵列104中的M个振动膜片阵列104的预设频率匹配，其中，M个振动膜片阵列104在接收到频率匹配的声波信号的情况下产生振动，M为小于或者等于N的正整数。
信号处理单元102可用于生成振动控制电信号，振动控制电信号可以理解为振动控制指令，用于指示振动的指令。声波信号发声单元103在接收到振动控制电信号时，可在振动控制电信号的驱动下进行声波信号的产生。
声波信号发声单元103可将M个振动控制电信号转换为M个声波信号，实现M个声波信号的生成，M个声波信号的频率分别与N个振动膜片阵列104中的M个振动膜片阵列104的预设频率匹配。可以理解，信号处理单元102基于M个振动膜片阵列104的预设频率，将M个振动控制电信号转换为M个声波信号，即将每个振动控制电信号转换为对应的声波信号，生成M个声波信号。M个振动控制电信号与M个声波信号一一对应，振动膜片阵列104与声波信号一一对应，每个振动膜片阵列104的预设频率与对应的声波信号的频率匹配。
振动膜片阵列104结构确定后，则其对应的预设频率确定，振动膜片阵列104中振动膜片1041的厚度、数量、间距以及形状等确定，则对应的预设频率确定。不同厚度、数量、间距或形状的振动膜片阵列104可具有不同的预设频率，在本实施例中，上述N个振动膜片阵列104的预设频率可以完全不同、部分相同或完全相同，振动膜片阵列104的预设频率可预先设置在终端设备100中。
如图2所示，为终端设备100的透视图，终端设备100包括设置于壳体101上的显示屏105，通过显示屏105进行显示信息。如图3所示，每个振动膜片阵列104包括至少两个振动膜片1041，振动膜片1041可在声波信号驱动下可发生振动，从而振动膜片阵列104在频率匹配的声波信号驱动下可发生振动。声波信号发声单元103在生成M个声波信号后将其输出，振动膜片阵列104在接收到M个声波信号中频率匹配的声波信号后发生振动，可以理解，M个振动膜片阵列104在接收到频率匹配的声波信号的情况下分别产生振动，且以对应频率匹配的声波信号的频率产生振动，即有M个振动膜片阵列104在振动。在一个示例中，上述预设频率为固有频率，其数值与振动膜片阵列发生共振情况下的共振频率相等，如此，振动膜片阵列在固有频率的声波信号的驱动下，可以以较大的振幅进行振动。在一个示例中，若预设频率为固有频率，M个振动膜片阵列104在接收到频率匹配的声波信号的情况下产生共振，具体为M个振动膜片阵列104在接收到频率匹配的声波信号的情况下分别产生共振，振动膜片阵列104发生共振时的频率为共振频率，数值与固有频率相同。
信号处理单元102和声波信号发声单元103设置在壳体101内，各振动膜片阵列104设置在壳体101上，且分布在壳体101的不同位置处，M个振动膜片阵列104在接收到频率匹配的声波信号的情况下分别产生振动，振动膜片阵列104振动可驱动终端设备100振动，即终端设备100中M个不同位置处产生振动，可增大终端设备100的振动强度。在一个示例中，M大于2，即可实现在至少2个不同位置处产生振动，进而确保终端设备100的振动强度。
本公开实施例的终端设备100中，设有置于壳体101不同位置处的N个 振动膜片阵列104，声波信号发声单元103根据振动控制电信号生成的声波信号驱动振动膜片阵列104振动，终端设备100不再利用振动马达实现振动，本公开实施例的终端设备100的N个振动膜片阵列104中的M个振动膜片阵列104是在接收到频率匹配的声波信号的情况下产生振动，以确保M个振动膜片阵列104能分别在对应频率匹配的声波信号的频率下分别产生振动，提高振动强度，且M个振动膜片阵列104设置在终端设备100的壳体101的不同位置处，可在M个不同位置处形成振动，从而提高振动强度，减少错过振动提示的情况发生。
如图4所示，在一个实施例中，终端设备100还包括设置在壳体101内的印刷电路板(Printed Circuit Board，PCB)106，信号处理单元102可以为信号处理芯片，可设置在上印刷电路板106。声波信号发声单元103可以为声波信号发生器，可设置在印刷电路板106上。上述初始电信号可从终端设备100的印刷电路板106发出，即信号处理单元102可从印刷电路板106接收上述初始电信号。例如，印刷电路板106在检测到有信息或来电等情况下，印刷电路板106可向信号处理单元102发送初始电信号，可触发信号处理单元102产生振动控制信号，以驱动声波发声单元103生成声波信号以驱动振动膜片阵列104振动。
信号处理单元102接收印刷电路板106发送的初始电信号，可对其进行优化处理，比如，噪音过滤和信号放大等处理，可根据优化处理后的初始电信号生成M个振动控制信号，并传递给声波信号发生单元103，声波信号发生单元103接收信号处理单元102传递的振动控制电信号后，将其转换为与振动膜片阵列104的预设频率匹配的声波信号，并将声波信号输出。振动膜片阵列104在收到频率匹配的声波信号后产生振动，带动终端设备100振动，即实现终端设备100的振动功能。
在一个实施例中，终端设备100包括但不限于移动终端和智能终端，上述移动终端包括但不限于手机、平板电脑、笔记本电脑、掌上电脑、车载移动终端、可穿戴设备以及计步器等。上述智能终端包括但不限于智能电视以及运动设备等。
在一个实施例中，上述M个声波信号的频率分别与M个振动膜片阵列 104的预设频率匹配，可以理解为，M个声波信号的频率中每个声波信号的频率与对应频率匹配的振动膜片阵列104的预设频率相同，或者每个声波信号的频率与对应频率匹配的振动膜片阵列104的预设频率之间的频率差的绝对值小于预设误差值，如此，可确保振动膜片阵列104能够以预设频率振动，确保振动强度，或者以在预设频率的预设误差范围内的频率振动，以确保振动膜片阵列104能在更宽的频率范围内振动，增强振动性能。
在一个实施例中，声波信号发声单元103在接收到M个振动控制信号后，可获取M个振动控制电信号对应的时间信息，基于M个振动控制电信号对应的时间信息以及时间段与振幅的对应关系，获取M个时间信息对应的预设振幅，然后基于所述M个振动膜片阵列104对应的预设频率以及所述时间信息对应的预设振幅，生成所述M个声波信号，所述M个声波信号的振幅分别与所述对应的预设振幅相同。
预先在终端设备100中设置有预设的时间段与振幅的对应关系，在获得时间信息后，可根据预设的时间段与振幅的对应关系，获取该时间信息对应的预设振幅，生成振幅与预设振幅相同的声波信号，声波信号传递至对应的振动膜片阵列104后，可驱动振动膜片阵列104以该预设振幅产生振动。
可以理解，可预先设置在不同时间段对应的振幅，即不同时间段对应的振幅可以不同，如此，在获得时间信息后，可确定时间信息所在的时间段，进而可确定对应的预设振幅，然后生成振幅为该预设振幅的声波信号并输出，以确定对应的振动膜片阵列104以该时间信息对应的预设振幅产生振动。如此，可在不同时间段进行不同振感强度的振动，满足用户对振动强度的个性化需求。
例如，在早上时间段8点到9点期间，对应的振幅为A1，在早上9点以后到晚上6点期间，对应的振幅为A2，在晚上6点以后的时间段内，对应的振幅为A3，A1小于A2，A2大于A3，A3大于A1。在接收到振动控制电信号后，确定的时间信息为早上8点30分，则可确定对应的预设振幅为A1，则生成振幅为A1的声波信号并输出，对应的振动膜片阵列104接收到该声波信号后产生振动，且振动的振幅为A1。
在一个实施例中，信号处理单元102可接收作用于所述终端设备100的 时间段输入以及与所述时间段输入对应的振幅输入，确定预设时间段以及与所述预设时间段对应的振幅；然后基于所述预设时间段以及所述预设时间段对应的振幅，确定所述预设的时间段与振幅的对应关系。后续声波信号发声单元103可获取该预设的时间段与振幅的对应关系，并依此获取M个时间信息对应的预设振幅。
用户可在终端设备100上进行输入操作，实现对时间段以及对应振幅的设定。具体地，在终端设备100上进行时间段输入以及与时间段输入对应的振幅输入，信号处理单元102可接收作用于所述终端设备100的时间段输入以及与所述时间段输入对应的振幅输入，即可确定预设时间段以及与预设时间段对应的振幅，例如，上述早上时间段8点到9点期间，对应的振幅为A1，在早上9点以后到晚上6点期间，对应的振幅为A2，在晚上6点以后的时间段内，对应的振幅为A3。基于预设时间段以及预设时间段对应的振幅，即可建立预设的时间段与振幅的对应关系，后续在声波信号发声单元103获得M个振动控制电信号对应的时间信息后，即可获取该预设的时间段与振幅的对应关系，利用该对应关系确定时间信息对应的预设振幅。
在一个实施例中，信号处理单元102可接收作用于终端设备100的膜片阵列选择操作，确定M个振动膜片阵列104。
由于在终端设备100中设置有N个振动膜片阵列104，可利用N个振动膜片阵列104中的M个振动膜片阵列104产生振动以带动终端设备100的振动，从而可在在接收到M个振动控制电信号的情况下，根据M个振动控制电信号生成M个声波信号之前，从N个振动膜片阵列104中确定M个振动膜片阵列104，即可在终端设备100上进行膜片阵列的选择，信号处理单元102可接收作用于终端设备100的膜片阵列选择操作，基于膜片阵列选择操作可确定M个振动膜片阵列104，信号处理单元102根据确定的M个振动膜片阵列104生成M个振动控制信号，后续声波信号发声单元103根据M个振动信号，可生成确定的M个振动膜片阵列104对应的M个声波信号，以驱动M个振动膜片阵列104产生振动。
在本实施例中，可根据用户针对不同场景下对振动的需求，进行振动膜片阵列104的选择，进而实现不同强度的振动，即实现不同应用场景下的振 动，可满足用户差异化的个性化需求。例如，用户通过终端设备100进行拳击游戏或赛车游戏时，需要较强的振感体验，用户可在终端设备100上进行振动膜片阵列104的选择，比如，可选择N个振动膜片阵列104进行振动，此时M与N相等，后续N个振动膜片阵列104在接收到频率匹配的声波信号后分别发生振动，以满足用户对较强振感的需求。又例如，用户在开会，需要较弱的振感体验，用户可在终端设备100上进行振动膜片阵列104的选择，比如，可选择N个振动膜片阵列104中的2个振动膜片阵列104进行振动，后续2个振动膜片阵列104在接收到频率匹配的声波信号后分别发生振动，以满足用户对较弱振感的需求。
如图1和2所示，在一个实施例中，壳体101包括中框，N个振动膜片阵列104间隔设置于中框。
以终端设备100为手机为例，上述中框即为手机中框，振动膜片阵列104之间存在间隔距离，如此，M个振动膜片阵列104能产生的具有一定间隔距离的振动，能带动终端设备100进行强度更大地振动。且将N个振动膜片阵列104设置于中框，可避免N个振动膜片阵列104占用终端设备100其他容纳空间影响终端设备100的其他单元的布局，用户持有该终端设备100时，设置在中框的N个振动膜片阵列104更加靠近用户，振动膜片阵列104的振动带动终端设备100振动时，振动能快速传递给用户，即用户能更加快速地感知到终端设备100的振动。
在一个实施例中，N个振动膜片阵列104均匀分布于中框。如此，能实现终端设备100的均匀振动，避免振动不均匀影响终端设备100中的其他单元。
在一个实施例中，中框为四边形，N个振动膜片阵列104均匀分布于中框的四条侧边。
即中框包括四条侧边，四条边框围设形成中框，在每条侧边上均设置有振动膜片阵列104，且N个振动膜片阵列104均匀分布于中框的四条侧边，以实现振动膜片阵列104的均匀分布，从而确保终端设备100的均匀振动。
如图1-2所示，在一个实施例中，N个振动膜片阵列104中位于中框的同一侧边的相邻振动膜片阵列104之间的间隔距离相同。
设置在相同侧边上的相邻振动膜片阵列104之间的间隔距离相同，即每个侧边上的振动膜片阵列104等间距分布，以实现每个侧边上等间距地产生振动，从而可带动终端设备100更加均匀振动，以确保终端设备100性能。
在一个实施例中，中框的四条侧边包括第一侧边、第二侧边、第三侧边和第四侧边，第一侧边的一端连接第二侧边的一端、第二侧边的另一端连接第三侧边的一端，第三侧边的另一端连接第四侧边的一端，第四侧边的另一端连接第一侧边的另一端，第一侧边分别与第二侧边以及第四侧边垂直，第三侧边分别与第二侧边以及第四侧边垂直，在第一侧边、第二侧边、第三侧边以及第四侧边分别设置有至少一个振动膜片阵列104。
可以理解，中框为正四边形，第一侧边与第三侧边平行，第二侧边和第四侧边平行，如此，处在第一侧边的振动膜片阵列104于处在第三侧边的振动膜片阵列104平行，处在第二侧边的振动膜片阵列104于处在第四侧边的振动膜片阵列104平行，在中框的每条侧边上至少设置一个振动膜片阵列104，可确保振动强度。
在一个实施例中，振动膜片1041的表面为凸面，包括第一凸面以及与第一凸面相对且相连的第二凸面。
在本实施例中，将振动膜片1041的表面设置为凸面，具体包括第一凸面以及与第一凸面相对且相连的第二凸面，如此可确保振动的稳定性，从而提高振动效果。在一个示例中，第一凸面与第二凸面的面积相同且对称，如此可确保振动膜片1041的表面的匀称，提高振动效果。
在一个实施例中，上述振动膜片阵列104可通过注塑成型方式设置在壳体101上，也可以通过焊接方式设置在壳体101上，又或者振动膜片阵列104为一体化结构的膜片模组，设置在壳体101上。
参照图5，在一个实施例中，提供了一种振动控制方法，可应用于上述终端设备100，该方法包括：
步骤501：在接收到M个振动控制电信号的情况下，根据M个振动控制电信号生成M个声波信号，M个声波信号的频率分别与N个振动膜片阵列104中的M个振动膜片阵列104的预设频率匹配。
终端设备100中的信号处理单元102接收振动控制电信号后将其传递给 声波信号发声单元103，声波信号发声单元103在接收到信号处理单元102传递的M个振动控制电信号时，根据M个振动控制电信号生成M个声波信号，M个声波信号的频率分别与N个振动膜片阵列104中的M个振动膜片阵列104的预设频率匹配。振动膜片阵列104与声波信号一一对应，振动膜片1041的预设频率与对应的目标声波信号的频率匹配。
步骤502：将M个声波信号输出，M个振动膜片阵列104在接收到频率匹配的声波信号的情况下产生振动。
声波信号发声单元103生成M个声波信号后将M个声波信号输出，设置在壳体101上的M个振动膜片阵列104在接收到频率匹配的声波信号的情况下产生振动。
上述振动控制方法，不再利用振动马达实现振动，而是通过N个振动膜片阵列104中的M个振动膜片阵列104接收到频率匹配的声波信号的情况下产生振动，以确保M个振动膜片阵列104能分别在对应频率匹配的声波信号的频率下分别产生振动，提高振动强度，且M个振动膜片阵列104设置在终端设备100的壳体101的不同位置处，可在M个不同位置处形成振动，从而提高振动强度。
在一个实施例中，根据M个振动控制电信号生成M个声波信号，包括：获取M个振动控制电信号分别对应的时间信息；基于时间段与振幅的对应关系，获取M个时间信息分别对应的预设振幅；基于M个振动膜片阵列104分别对应的预设频率以及M个时间信息分别对应的预设振幅，生成M个声波信号，M个声波信号的振幅分别与对应的预设振幅相同。
在一个实施例中，基于预设的时间段与振幅的对应关系，获取时间信息对应的预设振幅之前，还包括：接收作用于终端设备100的时间段输入以及与时间段输入对应的振幅输入，确定预设时间段以及与预设时间段对应的振幅；基于预设时间段以及预设时间段对应的振幅，确定预设的时间段与振幅的对应关系。
在一个实施例中，在接收到M个振动控制电信号的情况下，根据M个振动控制电信号生成M个声波信号之前，还包括：
接收作用于终端设备100的膜片阵列选择操作，确定M个振动膜片阵列 104。
本公开实施例依据共振原理设计了共振膜片阵列，在强化振感、避免漏失讯息及来电的问题同时可以给用户带来全方位立体的振感体验，且多位置、多频率的振动膜片阵列104的设置可以实现不同振感的私人差异化定制(例如，可满足游戏体验、商务办公等多种场景差异化需求)，极大提升用户体验。
本公开实施例提供的振动控制方法中的技术特征与上述终端设备100的技术特征对应，通过终端设备100实现上述振动控制方法的各个过程，并能得到相同的效果，为避免重复，在此不再赘述。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如只读存储器(Read Only Memory，ROM)/随机存取存储器(Random Access Memory，RAM)、磁碟、光盘)中，包括若干指令用以使得一台终端设备100(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本公开各个实施例的方法。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
上面结合附图对本公开的实施例进行了描述，但是本公开并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本公开的启示下，在不脱离本公开宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本公开的保护之内。
