由于物理按键功能单一，并需要占用一定空间，因此通过引入压力传感器可以丰富按键功能。压力传感器可以检测对按键施加的按压力度，进而根据不同的按压力度触发不同的应用程序，从而使得同一按键可以根据不同的按压力度实现不同的按键功能。
现有方案使用压力传感器和线性电机相结合，压力传感器检测按键被施加的按压力度，并根据不同的按压力度向线性电机输出不同的驱动电压，以使得线性电机内的弹簧振子在不同驱动电压的控制下产生力的作用，并将力传递到按键上。
在现有技术方案中，线性马达本身具有结构复杂和尺寸大的特点，此外，现有方案还需要额外的压力传感器，终端设备中放置压力传感器和线性马达需要较大尺寸空间，因此，现有压力传感器结合线性电机方案占用的尺寸空间较大，导致安装设计难度较大。

具体实施方式
本申请实施例提供了一种确定目标操作的方法、压力检测装置及终端设备，能够减小压力检测装置的空间尺寸，同时降低压力检测装置的成本。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必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，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
为了便于理解，下面将结合图1对本申请中确定目标操作的方法对应的系统框架进行说明。如图1所示，包括：压电陶瓷101和控制器102，控制器102与压电陶瓷101相连接。众所周知，压电陶瓷是一种具有压电效应的功能性陶瓷，是压电材料中的一种，其中，压电效应是指由应力诱导极化(或电场)，或由电场诱导出应力(或应变)的现象，前者称之为正压电效应，后者称之为负压电效应，两者统成为压电效应。另外，压电陶瓷的正压电效应如图2所示，由于对压电陶瓷施加外力作用，使得压电陶瓷自身产生振动，诱导压电陶瓷产生电场(或电力)，压电陶瓷的负压电效应如图3所示，向压电陶瓷两个面上施加电场(或电力)，使得压电陶瓷诱变产生形变(或振动)。
在了解了上述系统结构之后，下面将结合具体的实施例对本申请中确定目标操作的方法进行说明，具体实施方式如下所述：
需要说明的是，本申请中的确定目标操作的方法应用于一种压力检测装置中，该压力传感器包括控制器和压电陶瓷，如图4所示，本申请中确定目标操作的方法的一个实施例，包括：
401、压电陶瓷接收第一压力并产生第一形变量。
本实施例中，压电陶瓷接收外界作用于该压电陶瓷上的第一压力，进而，压电陶瓷产生第一形变量。
402、压电陶瓷根据第一形变量生成第一电压。
本实施例中，由于压电陶瓷具有正压电效应，压电陶瓷根据第一形变量产生第一电压，在正压电效应中，第一形变量和第一电压之间具有正相关关系，简而言之，第一形变 量越大对应压电陶瓷产生的第一电压也就越大，第一形变量越小对应压电陶瓷产生的第一电压也就越小，并且压电陶瓷将第一电压输出至控制器，或者由控制器检测压电陶瓷产生的第一电压。
可选地，在一种具体的实施方式中，压力检测装置还包括指纹传感器，将指纹传感器与压电陶瓷相贴合，在按压指纹传感器的同时，压电陶瓷会产生第一形变量，从而生成第一电压。
可选地，在另一种具体的实施方式中，压力检测装置还包括壳体，将压电陶瓷贴合于壳体内部，并且控制器也位于壳体内部，在从壳体外侧按压壳体和压电陶瓷贴合处时，压电陶瓷会产生第一形变量，从而生成第一电压。
可选地，在又一种具体的实施方式中，压力检测装置还包括指纹传感器和壳体，此时存在以下两种情况：
第一种，壳体覆盖指纹传感器以及压电陶瓷，具体的，指纹传感器的一面与壳体内侧贴合，指纹传感器的另一面与压电陶瓷贴合，控制器、指纹传感器和压电陶瓷均位于壳体内侧，在从壳体外侧按压壳体和指纹感器贴合处时，压电陶瓷会产生第一形变量，从而生成第一电压；
第二种，壳体表面开设通孔，指纹传感器置于通孔中并且表面暴露于壳体，具体的，指纹传感器与压电陶瓷相贴合，此时，按压通孔中的指纹传感器可以使得压电陶瓷产生第一形变量，从而生成第一电压。
需要说明的是，上述壳体的材料可以为玻璃，也可以为金属，对此本申请不做任何限制。
403、控制器根据第一电压确定第一压力的压力值。
本实施例中，压电陶瓷将其产生的第一电压输出至控制器，控制器接收第一电，根据公式(1)和第一电压获得第一压力的压力值，该第一压力为外界直接或间接作用于压电陶瓷的压力。其中，第一电压与第一压力的压力值之间具有正相关关系，其具体关系如下公式所示：
Figure PCTCN2017096754-appb-000001
其中，U为第一电压，h为压电陶瓷的厚度，A为压电陶瓷的受力面积，F为第一压力，g33为压电电压常数，不同的压电陶瓷对应的压电电压常数不同。
从上述公式中，可以看出第一电压越大对应检测得到第一压力的压力值越大，第一电压越小对应检测得到的第一压力的压力值越小。
404、控制器根据第一压力的压力值确定目标操作。
本实施例中，控制器根据第一压力的压力值确定目标操作，其中，目标操作为根据第一压力的压力值预先设定的待执行操作。
可选地，控制器根据第一压力的压力值和第一预设关系确定目标操作，其中，第一预设关系为各第一压力范围与各预设操作之间的一一对应关系，控制器根据第一预设关系确定该第一压力的压力值所属的一个第一压力范围所对应的预设操作为目标操作。
可以理解的是，控制器可以根据第一压力的压力值，确定该第一压力的压力值所属的压力范围，根据第一预设关系，确定该第一压力的压力值对应的预设操作确定为目标操作，换言之，控制器可以根据第一压力的压力值不同来确定不同的目标操作，因此，本申请可以实现根据不同的按压力度实现不同的操作。
例如，将上述压力检测装置置于手机或可穿戴设备中，将压力范围可以简单的划分为压力范围一和压力范围二，压力范围一为F1≤F≤F2，压力范围二为F2＜F≤F3，F为获得的第一压力的压力值。假设，压力范围一为轻按，压力范围二为重压。压力范围一对应的目标操作例如可以为返回上一个界面，压力范围二对应的目标操作例如可以为返回主界面。当在压电陶瓷上施加第一压力，压电陶瓷产生第一形变量，并根据第一形变量产生第一电压，此时，控制器根据第一电压可以获得第一压力的压力值F，如果F处于压力范围一，则控制器执行返回上一个界面的操作；如果F处于压力范围二，则控制器执行返回主界面的操作。
需要说明的是，上述压力范围一和压力范围二的具体压力范围可以根据实际应用场景进行设定，本申请不做任何限制。压力范围也不仅仅可以划分为两个，还可以根据实际需要做更多细分，以使得处于不同的压力范围的压力值对应不同的目标操作，使得操作更多样化，在此也不做限定。
405、控制器根据第一压力的压力值和第二预设关系确定第二电压。
其中，第二预设关系为各第二压力范围与各第二电压之间的对应关系，各第二电压的频率和幅值不同，第二预设关系中的各第二压力范围可以与第一预设关系中的各第一压力范围相同，也可以不同。
控制器确定了第一压力的压力值后，根据第二预设关系确定该第一压力的压力值所属的一个第二压力范围所对应的一个第二电压。
众所周知，人体皮肤组织包括角质层、透明层等组成，并且不同层分部有不同细胞。
如图5所示，曲线1为皮肤组织中的默尔克细胞复合体可以感知的频率和幅度；曲线2为皮肤组织中的梅氏小体可以感知的频率和幅度；曲线3为皮肤组织中的巴西尼小体可以感知的频率和幅度；曲线4为皮肤组织中的鲁菲尼小体可以感知的频率和幅度；上述四种细胞在人体皮肤组织中的分布(包括深度)不同，所以不同频率和不同幅值的振动给人的感受不同。
第二预设关系可以根据图5所示的频率和幅值之间的关系进行设置，以使得第二电压的频率和幅值与图5所示的频率和幅值相对应，即根据第二电压，压电陶瓷可以产生用户可以感知的震动反馈。
另外，在一些实际应用场景中，第二预设关系还可以为各第二压力范围与各第二电压组之间的对应关系，控制器可以根据第二预设关系确定该第一压力的压力值所属的一个第二压力范围对应的一个第二电压组，即确定多个不同频率和幅值的第二电压，例如：控制器可以生成频率为f且幅度为A的第二电压、，频率为f/2且幅度为A/2的电压、以及频率为f/4且幅度为A/4的电压，随之控制器将上述三个第二电压都输出给压电陶瓷，从而实现对用户按压的多级反馈，需要说明的是，对于上述三个电压之间的频率和幅度可以根据 衰减规律进行确定，该衰减规律可以根据大量实验数据确定，对此本申请不做任何限定。
还需要说明的是，对于步骤405和步骤404的执行顺序不做限定。
406、压电陶瓷根据第二电压产生第二形变量。
本实施例中，控制器将第二电压输出至压电陶瓷，由于负压电效应，压电陶瓷根据第二电压产生第二形变量，从而使得按压于压电陶瓷表面的用户手指等部位可以感受到压电陶瓷的震动反馈。
可选择的，第一电压大于第二电压，由压电陶瓷的特性可知，压电陶瓷根据第二电压产生的第二形变量小于压电陶瓷接收第一压力产生的第一形变量。
可以理解的是，假如用户通过手指对压电陶瓷施加第一压力，压电陶瓷产生第一形变量，控制器根据第一形变量确定第一压力的大小并确定第二电压，压电陶瓷根据第二电压产生第二形变量并反馈于用户的手指，此时，用户就会感受到自己施加的按压的反馈震动。
上述压力检测方法无需辅助如线性马达之类的器件，只需使用压电陶瓷这种特殊的压力传感器即可，需要说明的是，压力传感器均需要与相应的控制器配合使用，现有技术中也不例外。因此，本申请实施例可以有效地降低压力检测装置的空间尺寸，同时也节省了压力检测装置的成本。
上述实施例一对本申请中确定目标操作的方法进行了详细说明，下面将从以下方面对本申请中的压力检测装置进行说明。
实施二，如图1所示，本申请中压力检测装置的一个实施例包括：
压电陶瓷101和控制器102，并且，控制器102与压电陶瓷101之间的连接方式如图1所示；

控制器102，用于根据上述第一电压获得上述第一压力的压力值，并根据上述第一压力的压力值确定目标操作，上述目标操作为根据上述第一压力的压力值预先设定的待执行操作。
可选地，在一种可能的设计中，控制器102具体用于：根据上述第一压力的压力值和第一预设关系确定目标操作，其中，上述第一预设关系为各第一压力范围与各预设操作之间的对应关系，上述第一压力的压力值在上述各第一压力范围中的一个第一压力范围内，上述目标操作为上述各预设操作的中的一个操作。
可选地，在一种可能的设计中，控制器102还用于：对上述第一电压进行检测得到上述第一压力的压力值，则上述控制器根据上述第一压力的压力值和第二预设关系确定第二电压，上述第二预设关系为各第二压力范围与各第二电压之间的对应关系；并向压电陶瓷101输出第二电压。
可选地，在一种可能的设计中，压电陶瓷101还用于：若压电陶瓷101接收到控制器102输出的上述第二电压，则根据上述第二电压产生第二形变量，上述第二电压与上述第二形变量之间具有正相关关系。
在实施例二中，压力检测装置通过控制器102检测压电陶瓷101输出的第一电压，得 到第一压力，并且控制器102根据上述第一压力与第一预设关系确定目标操作，可以理解的是，假如人用手指按压该压力检测装置中的压电陶瓷101，那么控制器102便可以根据人的不同按压力度确定不同的目标操作，例如，重按对应目标操作：回到主界面；在锁屏状态下轻按对应目标操作：解锁。因此，本申请中的压力检测装置可以有效地实现确定目标操作的方法，并且使用压电陶瓷作为检测元件可以有效地减少压力检测装置的体积，同时，不用其他如线性马达之类的附加器件，可以有效地节约成本。
可选地，如图6所示，本申请中压力检测装置还包括：玻璃盖板601、指纹传感器603和手机壳体604，玻璃盖板601例如可以为手机壳体604上侧面，指纹传感器603一面与玻璃盖板601相贴合，指纹传感器603另一面与压电陶瓷602相贴合，指纹传感器603与压电陶瓷602位于手机壳体604内部，并且指纹传感器603与压电陶瓷602被手机壳体604所覆盖。
可选地，如图7所示的连接方式，在玻璃盖板601上开一通孔，并将指纹传感器603放置于该通孔中，使得指纹传感器603暴露于玻璃盖板601，对于其他可能的连接方式，本申请不做任何限制。
其中，需要说明的是，手机壳体604上侧面的玻璃盖板601也可以由其他材质构成，如金属等，对此本申请不做任何限制。
还需要说明的是，指纹传感器603用于进行指纹验证功能的传感器，也可以替换为其他类似功能的传感器，对此本申请不做任何限制。
可选地，在一种可能的设计中，压力检测装置还包括：壳体，压电陶瓷与壳体内侧贴合，控制器置于壳体内，并且壳体覆盖压电陶瓷，此时，基于施加于壳体外侧上的力，压电陶瓷接收第一压力产生第一形变量。
可选地，在一种可能的设计中，压力检测装置还包括：壳体和按键，壳体上有通孔，按键与压电陶瓷贴合，以使得当按压按键时，压电陶瓷也被按压产生第一形变量，然后将按键置于通孔中，使得按键暴露于壳体表面且压电陶瓷置于壳体内部，此外，控制器也位于壳体内部，此时，基于施加于按键上的力，压电陶瓷接收第一压力产生第一形变量。
如图8所示为将四个压电陶瓷应用用于手机终端的一个结构示意图，右上侧边沿上的压电陶瓷用于构成手机终端上的音量键；下边沿上的三个压电陶瓷用于构成手机终端上的三个功能键。需要说明的是，本申请中的压力检测装置不仅可以用于手机终端，还可以用于其他终端设备如可穿戴设备上；另外，一个终端设备上可以包括至少一个压电陶瓷，可视实际应用场景进行设置，对此本申请不做任何限制。
