一种触摸方法及电子设备
本申请要求在2019年4月29日提交中国国家知识产权局、申请号为201910356478.0的中国专利申请的优先权，发明名称为“一种触摸方法及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，尤其涉及一种触摸方法及电子设备。
背景技术
智能手机已经逐渐深入到人们的生活并广泛应用于生活中，同时人们对智能手机的要求越来越高，而带有触控屏的手机也因其操作方便、屏幕大、整体简洁漂亮而越来越受到人们的喜爱。
然而，用户使用带有触控屏的手机时，若手指在触控屏上滑动，参见图1所示，可能会因为手指和触控屏之间的摩擦力，而导致手指在滑动过程中有阻塞感，尤其是当手指长时间在触控屏上滑动时，阻塞感会更加明显，从而影响用户的滑动体验。
发明内容
有鉴于此，本申请提供一种触摸方法及电子设备，用以减小用户的手指触摸所述触控屏的阻塞感，提高用户的滑动体验。
第一方面，本申请实施例提供了一种触摸方法，包括：若确定存在用户的手指对触控屏的触摸操作，则控制超声波发射器发射超声波信号。其中，超声波发射器可以设置在触摸屏的下方，超声波发射器发射的超声波信号作用于用户的手指，使得用户的手指与触控屏的接触部位形成气泡空间。
采用上述方法，由于存在触摸操作时，控制所述超声波发射器发射超声波信号，使得用户的手指与触控屏的接触部位形成气泡空间，从而能够减少手指与触控屏的接触面积，减少阻塞感，提高用户的滑动体验和满意度。
在一种可能的设计中，若确定存在用户的手指对触控屏的触摸操作，且触摸操作的持续时长大于或等于预设阈值，则控制超声波发射器发射超声波信号。
采用这种方式，考虑到用户触摸操作的持续时长较短时，可能不会存在明显的阻塞感，因此若触摸操作的持续时长小于预设阈值，则可以暂不发射超声波信号，而是在触摸操作的持续时长大于或等于预设阈值时发射超声波信号，从而能够在提升触感的基础上，有效节省超声波发射器的功耗。
在一种可能的设计中，可以根据连续出现的存在触摸操作的画面帧数，确定触摸操作的持续时长。
在一种可能的设计中，控制超声波发射器发射超声波信号之后，若确定用户的手指停止对触控屏的触摸操作，则可以控制超声波发射器停止发射超声波信号。

在一种可能的设计中，超声波发射器发射的超声波信号形成波束，触控屏的整个屏幕位于波束的覆盖范围内。
如此，由于触控屏的整个屏幕位于波束的覆盖范围内，因此当用户的手指在触控屏上的任一位置滑动时，超声波发射器发射的超声波信号均能够作用于用户的手指。
在一种可能的设计中，超声波发射器设置在触控屏的下方，可以是指超声波发射器设置在触控屏的中心区域的下方。

在控制超声波发射器发射超声波信号之前，确定触摸操作的持续时长大于或等于预设阈值。
在一种可能的设计中，处理器还被配置为以执行如下步骤：

为了便于理解，示例性地给出了部分与本申请实施例相关概念的说明以供参考。
(1)超声波：通常情况下，频率高于20000赫兹(Hz)的声波称为超声波。人耳朵能听到的声波频率为20～20000Hz，当声波的振动频率大于20000Hz时，人耳无法听到，由于超声波的频率下限大约等于人的听觉上限，因此称为超声波。
(2)超声波发射器：也可以称为超声波声源，用于发射超声波信号。或者，还可以为其它名称，本申请实施例对此不做限定。
(3)帧率(frame rate)：是以帧为单位的位图图像连续出现在显示器上的频率(速率)，比如，帧率为60Hz，也就是1秒钟连续出现60帧画面，即每隔16.67ms(1000/60)出现一次画面。
如背景技术所述，当用户的手指长时间在触控屏上滑动时，会因存在阻塞感而影响触感。基于此，本申请实施例提供触摸方法，用于减少手指与触控屏之间的摩擦力，进而提升触感。

本申请实施例中，触控屏下方设置有超声波发射器160。在一个示例中，参见图3所示，触控屏可以为一种堆叠结构，从上到下依次主要是触控面板(touch panel，TP)层、显示层，其中，触控面板层即为触控面板所在的层，显示层可以理解为显示屏所在的层。需要说明的是，图3仅是一种简单的示例说明，实际场景中，触控屏还可以包括其它层，本申请实施例对此不作限定。示例性地，触控屏下方设置有超声波发射器160可以理解为：显示层的下方设置有超声波发射器层，超声波发射器层为超声波发射器所在的层。本申请实施例中，参见图4中的(a)至(c)所示，超声波发射器可以设置在触控屏的任一区域的下方，比如，在(a)中，超声波发射器设置在触控屏的左上角区域的下方，在(b)中，超声波发射器设置在触控屏中心区域的下方，在(c)中，超声波发射器设置在触控屏的右下角区域的下方。
需要说明的是，超声波发射器可以位于触控屏的下方且紧贴触控屏，或者也可以位于触 控屏的下方但并没有紧贴触控屏；本申请实施例对超声波发射器的具体位置不作限定，只要能够保证超声波发射器发射的超声波信号可以传递到触控屏从而作用于用户的手指即可。

参见图5，在本申请实施例中，处理器与触控屏、超声波发射器相连接，其中，超声波发射器上可以设置有开关，用于控制所述超声波发射器160的开启和关闭状态。触控屏监测到用户的手指的触摸操作后，可以将该触摸操作传递给处理器，比如通过监测信号将触摸操作传递给处理器，如此，处理器可以确定是否存在触摸操作以及触摸操作的持续时长。处理器可以向超声波发射器发送开启指令和关闭指令，相应地，超声波发射器若接收到开启指令，则发射超声波信号，若接收到关闭指令，则停止发射超声波信号。
基于图2和图5所示的硬件结构，本申请实施例提供一种触摸方法，参见图6所示的流程，该方法是由电子设备执行，比如可以由电子设备中的处理器执行，该方法包括如下步骤：
步骤601，确定存在用户的手指对所述触控屏的触摸操作。
具体来说，触控屏监测到用户的手指的触摸操作后，可以将该触摸操作传递给处理器，如此，处理器可以确定存在所述触摸操作。
步骤602，控制所述超声波发射器发射超声波信号。其中，控制超声波发射器发射超声波信号的具体实现方式可以有多种，比如可以向超声波发射器开启指令。
本申请实施例中，超声波发射器发射的超声波信号作用于用户的手指，使得用户的手指与触控屏的接触部位形成气泡空间，参见图7所示。由于超声波信号传播过程中存在着正负压强交变周期，在正相位时，对介质分子产生挤压，增加介质原来的密度，在负相位时，介质分子稀疏、离散，介质密度减小，因此，当超声波信号作用于手指时会产生震荡，从而形成气泡空间。在一个示例中，用户的手指与触控屏的接触部位形成气泡空间可以真空气泡空间。
采用上述方法，由于存在触摸操作时，控制所述超声波发射器发射超声波信号，使得用户的手指与触控屏的接触部位形成气泡空间，从而能够减少手指与触控屏的接触面积，减少阻塞感，提高用户的滑动体验和满意度。
在一个示例中，处理器可以在确定触摸操作的持续时长大于或等于预设阈值的情况下，向超声波发射器开启指令；如此，超声波发射器接收到开启指令后可以发射超声波信号，其中，预设阈值可以是由本领域技术人员根据经验和实际需要来设置，比如预设阈值可以为3秒，或者预设阈值也可以为连续出现的存在所述触摸操作的画面帧数。采用这种方式，考虑到用户触摸操作的持续时长较短时，可能不会存在明显的阻塞感，因此若触摸操作的持续时长小于预设阈值，则可以暂不发射超声波信号，而是在触摸操作的持续时长大于或等于预设阈值时发射超声波信号，从而能够在提升触感的基础上，有效节省超声波发射器的功耗。
其中，处理器判断触摸操作的持续时长是否大于或等于预设阈值的方式可以有多种。在一种可能的实现方式中，处理器可以根据连续出现的存在触摸操作的画面帧数，确定触摸操 作的持续时长是否大于或等于预设阈值，比如，处理器确定在第i帧画面存在触摸操作后，则可以监测第i+1帧画面是否存在所述触摸操作，若存在则可以监测第i+2帧画面是否存在所述触摸操作，以此类推，若监测到第i+n帧画面仍存在所述触摸操作(预设阈值为n-1)，则可以确定触摸操作的持续时长达到预设阈值；又比如，处理器可以根据帧率以及连续出现的存在触摸操作的画面帧数来计算时长(比如画面帧数为180，帧率为60Hz，则时长为3秒)，进而将计算出的时长与预设阈值(比如3秒)进行比较。
本申请实施例中，考虑到用户的手指可能会滑动到触控屏上的任意位置，因此，为使得超声波发射器发射的超声波信号能够作用于用户的手指，本申请实施例提供两种示例性方式，分别为方式1和方式2。
方式1，超声波发射器可以向各个方向发射超声波信号。
方式2，超声波发射器基于预先设置的方向来发射超声波信号。其中，可以基于超声波发射器的位置来设置超声波发射器发射超声波信号的方向，从而使得触控屏的整个屏幕位于超声波信号形成的波束的覆盖范围内，比如若超声波发射器的位置为图4中的(a)所示意的情形，则超声波发射器的发射的超声波信号形成的波束可以为图8中(a)所示；若超声波发射器的位置为图4中的(b)所示意的情形，则超声波发射器的发射的超声波信号形成的波束可以为图8中(b)所示；若超声波发射器的位置为图4中的(c)所示意的情形，则超声波发射器的发射的超声波信号形成的波束可以为图8中(c)所示。采用这种方式，由于超声波发射器发射的超声波信号形成的波束覆盖触控屏的整个屏幕即可，从而能够有效节省超声波发射器的功耗。
示例性地，在上述步骤602之后，该方法还可以包括：步骤603或步骤604。
步骤603，若确定用户的手指停止对所述触控屏的触摸操作，则可以控制所述超声波发射器停止发射超声波信号。其中，控制所述超声波发射器停止发射超声波信号的具体实现方式可以有多种，比如可以向超声波发射器关闭指令，如此，超声波发射器接收到关闭指令后可以停止发射超声波信号。
步骤604，若确定触控屏处于灭屏状态(比如在触摸操作的持续过程中，用户触发了灭屏按键，导致触控屏处于灭屏状态)，则可以控制所述超声波发射器停止发射超声波信号。
本申请实施例中，在用户的手指停止对所述触控屏的触摸操作或者触控屏处于灭屏状态的情况下，控制超声波发射器停止发射超声波信号，能够有效节省超声波发射器的功耗。
示例性地，针对用户的手指在手机的触摸屏上进行触摸操作这一场景，本申请实施例结合上述触摸方法，按照如下几个阶段实现对超声波发射器的状态进行控制。
第一阶段，用户点亮手机的触控屏(比如用户可以通过指纹解锁进而点亮触控屏)使得触控屏处于亮屏状态，此时超声波传感器处于关闭状态。
第二阶段，用户执行触摸操作，比如用户的手指在触控屏上进行滑动，触控屏监测到用户的触摸操作，并将触摸操作传递给处理器；相应地，处理器确定存在触摸操作，并可进一步确定触摸操作的持续时长，若持续时长大于或等于预设阈值，则向超声波发射器发送开启指令；如此，超声波发射器接收到开启指令后，发射超声波信号。
第三阶段，用户停止触摸操作，比如用户的手指离开触控屏，触控屏监测到用户停止触摸操作后，可以传递给处理器；相应地，处理器可以向超声波发射器关闭指令，如此，超声波发射器接收到关闭指令后可以停止发射超声波信号。
综上，电子设备确定用户长时间进行触控操作时，利用超声波发射器发射超声波信号，从而使得用户的手指与触控屏的接触面积减小，有利于提升触感。
