技术领域
本申请涉及可穿戴设备技术领域，尤其涉及一种可穿戴设备、可穿戴设备的控制方法及其控制装置。
背景技术
随着真无线耳机(True Wireless Stereo，TWS)耳机的问世，TWS耳机越来越被广大的消费者接受。然而，随着人们对舒适度的要求越来越高，由于用户长期佩戴入耳式或贴耳式耳机会有明显的不适感，因此，人们开始寻求其他可穿戴设备代替入耳式或贴耳式耳机。
目前，一些其他可穿戴设备也具有发声和录音的功能，例如智能手环、手表等。然而，可穿戴设备还是主要采用传统的扬声器，由于传统扬声器的发声范围较大，从而会存在用户在通话场景中漏音的问题。
发明内容
本申请公开一种可穿戴设备、可穿戴设备的控制方法及其控制装置，以解决相关技术中可穿戴设备主要采用传统的扬声器，由于传统扬声器的发声范围较大而存在用户在通话场景中漏音的问题。
为了解决上述技术问题，本申请是这样实现的：
第一方面，本申请公开一种可穿戴设备，包括连接带和数字发声器，所述数字发声器设于所述连接带，所述数字发声器包括呈阵列分布的多个发声单元；其中，所述可穿戴设备根据所述数字发声器与用户的耳朵之间的相对 位置，控制所述多个发声单元中朝向耳朵的所述发声单元构成的一组所述发声单元向所述耳朵所处的位置发出超声波。
第二方面，本申请还公开一种可穿戴设备的控制方法，所述可穿戴设备为第一方面所述的可穿戴设备，所述控制方法包括：检测所述数字发声器与用户的耳朵的实际相对位置；根据所述实际相对位置，控制所述多个发声单元中朝向耳朵的所述发声单元构成的一组所述发声单元向所述耳朵所处的位置发出超声波。
第三方面，本申请还公开一种可穿戴设备的控制装置，所述可穿戴设备为第一方面所述的可穿戴设备，所述控制装置包括：检测模块：用于检测所述数字发声器与用户的耳朵的实际相对位置；控制模块：根据所述实际相对位置，用于控制所述多个发声单元中朝向耳朵的所述发声单元构成的一组所述发声单元向所述耳朵所处的位置发出超声波。
本申请采用的技术方案能够达到以下技术效果：本申请实施例公开的可穿戴设备通过在连接带上设置数字发声器，数字发声器包括呈阵列分布的多个发声单元，使得可穿戴设备可以根据数字发声器与用户的耳朵之间的相对位置，控制多个发声单元中朝向耳朵的发声单元构成的一组发声单元向耳朵所处的位置发出超声波，从而使得超声波可以在耳朵所处的位置处解调成可听声。由于超声波的方向性好，穿透能力强，易于获得较集中的声能，从而使得数字发声器可以较准确的向耳朵所处的位置发声，且声能较为集中，从而可以减少在通话场景中的漏音，从而可以有效地解决相关技术中可穿戴设备采用传统扬声器时由于传统扬声器的发声范围较大而存在用户在通话场景中漏音的问题。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请的一部分实施例，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在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
以下结合附图，详细说明本申请各个实施例公开的技术方案。
请参考图1至图12，本申请实施例公开一种可穿戴设备，所公开的可穿戴设备可以是手表、手环、扳指等。所公开的可穿戴设备包括连接带100和数字发声器200。用户在佩戴可穿戴设备时可以通过连接带100进行佩戴。
数字发声器200设于连接带100，数字发声器200包括呈阵列分布的多个发声单元210。
数字发声器200采用微机电(Micro Electro Mechanical System，MEMS)工艺制造，集成了驱动芯片，数字发声器200包括多个静电振动单元，静电振动单元即本申请中的发声单元210。在每个发声单元210工作时，发声单元210发出超声波产生振动脉冲。数字发声器200采用DSR(Digital Sound  Reconstruction)技术将前端输入的数字信号重构为模拟音频信号，在PCM(Pulse Coding Modulation，脉冲编码调制)音频信息的每个采样点，通过对应信号幅度确定所需发声单元210的数量，由多个发声单元210的高频脉冲能量积累达到所需声音信号的能量，不同信号幅度所需的发声单元210的数量不同，通过驱动芯片调制，整个过程由数字I2S信号直接重构为音频声信号。数字发声器200的定向发声原理为公知技术，这里不再赘述。
可穿戴设备根据数字发声器200与用户的耳朵之间的相对位置，控制多个发声单元210中朝向耳朵的发声单元210构成的一组发声单元210向耳朵所处的位置发出超声波，以使超声波可以在耳朵所处的位置处解调成可听声。在同一个数字发声器200内，该数字发声器200所包含的多个发声单元210的朝向不全相同。
具体的，朝向耳朵的发声单元210是指，所发出的超声波可以覆盖耳朵所处位置的发声单元210。在向耳朵发声时，可以根据信号幅度，在朝向耳朵的发声单元210中确定所需发声单元210的数量，以构成一组发声单元210，并向耳朵所处的位置发出超声波，以使超声波可以在耳朵所处的位置处解调成可听声。在朝向耳朵的发声单元210所构成的一组发声单元210可以是朝向耳朵的发声单元210中部分发声单元210组成。当然在一些的情况下，在朝向耳朵的所有发声单元210也可以共同构成的一组发声单元210。
说明一下，超声波可以在耳朵所处的位置处解调成可听声的原理。例如，该数字发声器200可以发出两束超声波，当然还可以是多束，利用超声波的高度指向性，能够使该两束超声波在空气中定向传播，同时，由于空气的非线性调解作用，使得两束超声波调解为多个声波，其中，通过合理选择数字发声器200发出两束超声波的频率，以使两束超声波的差频声波为可听声波，例如，数字发声器200发出两束频率为f1和f2的超声波，受空气非线性交互作用影响，两束频率为f1和f2的超声波调解为f1、f2、f1+f2、f1-f2、2f1、2f2等多束声波，其中，f1-f2为该差频声波。合理选择f1和f2的频率，能够使得f1-f2为可听声波，比如，f1＝41kHz，f2＝40kHz，f1-f2＝1kHz，1kHz频率的声波属于可听声波，且两束超声波经过空气非线性调解后的差频声波仍然具有高度指向性，从而使得该差频声波能够在空气中定向传播，进而使得声音能够定向传播。超声波定向传播的原理均为已知技术，为了文本简洁，在此不再赘述。
由于数字发声器200包括多个发声单元210，从而使得可穿戴设备可以灵活的调用朝向耳朵的多个发声单元210中不同的发声单元210组合，从而形成不同的发声阵列，再叠加相控阵技术，可实现指向性发声。每个发声单元210发出的声波为调制波，相应的发声阵列为参阵量，基于声频定向的发声原理来实现定向发声，利用空气的非线性来解调出可听声。
本申请的巧妙之处在于，对数字发声器200所包含的多个发声单元210进行适应性地抽取成组，并进行控制，使其能够通过向耳朵所在的位置发出超声波，并通过超声波在耳朵处解调成可听声，确保了声音的定向传输，从而确保通话的隐私性。
本申请实施例公开的可穿戴设备通过在连接带100上设置数字发声器200，数字发声器200包括呈阵列分布的多个发声单元210，使得可穿戴设备可以根据数字发声器200与用户的耳朵之间的相对位置，控制多个发声单元210中朝向耳朵的发声单元210构成的一组发声单元210向耳朵所处的位置发出超声波，从而使得超声波可以在耳朵所处的位置处解调成可听声。由于超声波的方向性好，穿透能力强，易于获得较集中的声能，从而使得数字发声器200可以较准确的向耳朵所处的位置发声，且声能较为集中，从而可以减少在通话场景中的漏音，从而可以有效地解决相关技术中可穿戴设备采用传统扬声器时由于传统扬声器的发声范围较大而存在用户在通话场景中漏音的问题。
在通过数字发声器200向耳朵所处的位置发声时，可以通过可穿戴设备上的红外成像模组检测人眼相对可穿戴设备的位置，根据人眼的位置与耳朵的位置的对应关系，确定耳朵与数字发声器200的相对位置。当然，在一些实施例中，可穿戴设备可以包括间隔分布的多个麦克风，多个麦克风可以用于获取声音信号，可穿戴设备可以用于根据多个麦克风获取的声音信号，确定声源位置以及根据声源位置确定耳朵与数字发声器的初始相对位置。通过初始相对位置能够明确数字发声器200所包含的所有发声单元210中哪些发声单元210是朝向用户的耳朵所在的位置。
在一些场景中，在用户佩戴可穿戴设备运动时，例如用户佩戴手表或手环转动手腕时，连接带100会存在绕其延伸方向的轴线转动。为了使连接带100绕其延伸方向的轴线转动时仍可以较好的向用户的耳朵发声，可选的，数字发声器200还可以包括基座220，基座220可以为数字发声器200的其 他部件提供安装的基础。基座220可以包括第一安装平面和第二安装平面，第一安装平面可以与第二安装平面形成折面，第一安装平面与第二安装平面衔接的边缘可以形成沿连接带的延伸方向延伸的凸棱230，第一安装平面和第二安装平面均可以设有呈阵列分布的多个发声单元210。
通过将基座220设置为包括第一安装平面和第二安装平面，且第一安装平面可以与第二安装平面形成折面，第一安装平面与第二安装平面衔接的边缘可以形成沿连接带的延伸方向延伸的凸棱230，使得第一安装平面和第二安装平面均可以设有呈阵列分布的多个发声单元210，由于第一安装平面与第二安装平面相对连接带100的表面倾斜设置，从而使得数字发声器200的发声覆盖范围更广，进而使得在连接带100绕其延伸方向的轴线转动时仍可以较好的向用户的耳朵发声。
在具体的应用场景中，在用户佩戴手表或手环向下垂放时，由于第一安装平面和第二安装平面形成折面，第一安装平面与第二安装平面衔接的边缘可以形成沿连接带的延伸方向延伸的凸棱230，第一安装平面与第二安装平面中的一个可在该场景下朝向用户的耳朵，从而朝向用户的耳朵的一侧的安装平面上的发声单元210向用户的耳朵所处的位置发声。在背向用户的耳朵的安装平面上的发声单元210不发出超声波，从而可以较好地防止漏音。
为了进一步提高数字发声器200发声可覆盖的范围，可选的，数字发声器200可以包括多个由内向外依次环绕设置的环状发声区240，多个环状发声区240由内向外的高度依次递减，即多个环状发声区240形成圆锥形结构，每个环状发声区240均可以间隔的设有发声单元210。
通过将数字发声器200设置为包括多个由内向外依次环绕设置的环状发声区240，多个环状发声区240可以由内向外的高度依次递减，每个环状发声区240均间隔的设有发声单元210，使得数字发声器200可以在环绕整个环状发声区240的范围内定向发声，从而使得用户在佩戴可穿戴设备进行任意姿势的变化时，都可以满足朝向用户的耳朵所处的位置发声。而且发声单元210设置于由内向外依次环绕设置的环状发声区240也使得集成度相对较高。
为了进一步提高数字发声器200的发声能力，可选的，数字发声器200可以包括中心发声区250，中心发声区250可以位于多个环状发声区240的中心，且高于多个环状发声区240中最内侧的环状发声区240，中心发声区 250可以设有发声单元210。
本申请合理的利用了环状发声区240的中心的区域设置发声单元210，从而使得发声单元210的数量更多，进而使得数字发声器200的发声能力更强。
一种可选的实施例，连接带100可以具有弧形段110，数字发声器200可以设于弧形段110，且数字发声器200的形状可以与弧形段110的形状相适配。通过将数字发声器200的形状设置为与弧形段110的形状相适配，可以利用弧形段110的结构，使得数字发声器200设于弧形段110，由于弧形结构本身就具有朝向范围大的特点，因此数字发声器200发声的覆盖范围更大，无需在连接带100上设置多个数字发声器200，从而一体化程度较高。
可选的，连接带100可以包括第一带体120和第二带体130，第一带体120和第二带体130可以分别连接于可穿戴设备的设备主体的两侧，以用于可穿戴设备的佩戴。第一带体120和第二带体130均可以设有数字发声器200。可穿戴设备可以围成环状结构佩戴于用户的手腕。通过在多个表带上均设置数字发声器200，从而使得可穿戴设备佩戴后绕环状结构的中心轴线转动时，第一带体120和第二带体130中的至少一个数字发声器200能够朝向用户的耳朵发声。
可选的，连接带100可以开设有安装槽140，数字发声器200可以设于安装槽140内。通过在连接带100上开设安装槽140，使得数字发声器200可以设于安装槽140内，从而使得数字发声器200安装于连接带100更稳定，而且安装槽140还可以对数字发声器200进行防护。
进一步的，可穿戴设备还可以包括防护盖板，防护盖板可以设于安装槽140，且覆盖数字发声器200，防护盖板可以开设有多个出音孔，防护盖板可以与安装槽140围成容纳空间，多个出音孔可以与容纳空间连通。
通过设置防护盖板，使得防护盖板可以设于安装槽140，且覆盖数字发声器200，从而使得防护盖板可以对数字发声器200进行防护。通过在防护盖板上开设多个出音孔，使得数字发声器200发出的超声波可以较好的穿过，从而可以在用户的耳朵所处的位置解调成可听声。
一种可选的实施例，可穿戴设备还可以包括设备主体300，设备主体300可以包括壳体310和电路板320，电路板320可以设于壳体310内，设备主体300可以与连接带100连接，连接带100的内部可以开设有与壳体310连 通的连接通道，数字发声器200可以与电路板320通过柔性电路板330电连接，柔性电路板330可以穿设于连接通道。
本申请实施例通过在连接带100的内部开设连接通道，从而可以便于柔性电路板穿设于连接通道电连接数字发声器200和电路板320，而且连接通道可以对柔性电路板进行防护。
在一些实施例中，可穿戴设备还包括充电座400和电池模组，充电座400用于对电池模组进行充电。
在一些实施例中，可穿戴设备还包括显示屏支架510和显示屏520，显示屏支架510用于与壳体310连接，显示屏520用于与显示屏支架510连接，显示屏520用于可穿戴设备的显示。

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。此外，需要指出的是，本申请实施方式中的方法和装置的范围不限按示出或讨论的顺序来执行功能，还可包括根据所涉及的功能按基本同时的方式或按相反的顺序来执行功能，例如，可以按不同于所描述的次序来执行所描述的方法，并且还可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
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，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以计算机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ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端(可以是手机，计算机，服务器，或者网络设备等)执行本申请各个实施例所述的方法。
本申请上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
上面结合附图对本申请的实施例进行了描述，但是本申请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申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
