图2是本发明实施例提供的一种可定向传声的智能手表的局部剖视图；
图3是本发明实施例提供的一种可定向传声的智能手表的***示意图；
图4是本发明实施例提供的一种可定向传声的智能手表中可听声束的传播示意图。
 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
需要说明的是，术语“设置”、“连接”应做广义理解，例如，可以是直接设置、安装、连接，也可以通过居中元部件、居中结构间接设置、连接。
另外，本发明实施例中若有“进”、“出”、“宽度”、“大”、“小”、“远”、“近”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系或常规放置状态或使用状态，其仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的结构、特征、装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在具体实施方式中所描述的各个具体技术特征和各实施例，在不矛盾的情况下，可以通过任何合适的方式进行组合，例如通过不同的具体技术特征/实施例的组合可以形成不同的实施方式，为了避免不必要的重复，本发明中各个具体技术特征/实施例的各种可能的组合方式不再另行说明。
如图1至图4所示，本发明实施例提供的一种可定向传声的智能手表，包括壳体1与连接于壳体1的表带4，壳体1的侧壁可开设有出音孔2，出音孔2处可设置有定向扬声器3，定向扬声器3的可朝向出音孔2，采用定向扬声器3代替传统的扬声器，使智能手表具有定向传声功能，而扬声器可位于壳体1内，可知，定向扬声器3发出的声音经由出音孔2定向传递至壳体1外；出音孔2可朝向于斜上方设置，使壳体1内定向扬声器3发出的声音能够沿用户最容易听到且不会影响到周围的方向传播，结构简单、紧凑，制作工序简易。本发明实施例提供的一种可定向传声的智能手表，其在公共场合通话时个人隐私可得到保护，同时在公共场合时发声不会造成噪音干扰，无需使用耳机来解决，不必时刻带着耳机，用户使用感佳，能够真正地解决问题。
如图3所示，可选地，壳体1内还可设置有电子元器件8、PCB板9和电池等。
如图1所示，可选地，壳体1的设置有出音孔2的侧壁可倾斜于壳体1的正面设置，出音孔2可垂直于设置有出音孔2的侧壁设置，使壳体1内定向扬声器3发出的声音能够沿用户最容易听到且不会影响到周围的方向传播，结构简单、紧凑，制作工序简易。
或者，作为出音孔2的另一种实现方式，壳体1设置有出音孔2的侧壁可垂直于壳体1的正面设置，出音孔2可倾斜于设置有出音孔2的侧壁设置。
如图1和图2所示，可选地，出音孔2可包括内出音孔21、出音孔道23和外出音孔22，内出音孔21、外出音孔22可分别设置于出音孔道23的两端，出音孔2可设置于壳体1的侧壁内侧，外出音孔22可设置于壳体1的侧壁外侧，即内出音孔21连接于壳体1内与出音孔道23，外出音孔22连接于壳体1外与出音孔道23，出音孔道23可连通于壳体1的侧壁内侧、侧壁外侧；
出音孔道23可与壳体1的正面之间形成有倾斜夹角α，倾斜夹角α的角度范围为10°-75°。可以理解地，传统的出音孔道垂直于壳体的水平面，当用户需要很好地听清扬声器发出的声音时，需要将手腕转动至一定的角度，听久了手腕会很累；而本实施例中智能手表的出音孔道23与壳体1的正面形成有倾斜夹角，当用户需要听清定向扬声器3发出的声音时，只需抬手将智能手表靠近耳边即可，无需转动手腕，并且倾斜夹角α的角度可根据不同用户的需求设置不同规格，可以满足不同用户的要求。
本实施例中，壳体1的侧壁位于壳体1内的一侧定义为壳体1的侧壁内侧；反之，壳体1的侧壁位于壳体1外的一侧定义为壳体1的侧壁外侧。
如图1和图3所示，可选地，出音孔2可位于壳体1侧壁连接于表带4处。可以理解地，若智能手表具有指针盘，则出音孔2位于壳体1侧壁且指针指向6点的位置，通常这个位置连接有表带4并且在佩戴、使用时靠近面部。
如图3和图4所示，可选地，定向扬声器3可以为微型声频定向扬声器，这种扬声器常应用于手机上，是通过免提的方式为用户提供局部声音服务，建立良好的私密性声音空间；将可听声音频信号调制到超声波信号中，利用超声波在信号中的非线性传播效应，通过超声换能器阵列产生出一系列沿传播轴分布的虚拟声源，这些虚拟声源又被称为参量阵，它们将声音控制在一个狭长的区域传播，进而形成具备高度指向性的可听声束7，从而实现智能手表通话时生音的定向传播。
如图1和图3所示，可选地，壳体1的一面可设置有显示屏5，另一面可设置有后盖6，即壳体1的正面设置有显示屏5，壳体1的背面设置有后盖6；内出音孔21可靠近于后盖6，外出音孔22可靠近于显示屏5，即佩戴智能手表且进行通话时，出音孔2朝向面部，利于用户听清声音。当然，内出音孔21也可以靠近于显示屏5，外出音孔22也可以靠近于后盖6，根据不同用户不同的佩戴、使用方式而定，结构简单、灵活。
如图1所示，可选地，内出音孔21的孔径可大于外出音孔22的孔径，有利于将定向扬声器3发出的声音集中传播，可进一步减小声音传播的范围，提高智能手表通话的保密性。
可选地，定向扬声器3可以具有前音腔31，前音腔31可朝向于出音孔2，使得声音更集中、更容易地从出音孔2处传输至壳体1外。
可选地，显示屏5可以为触控显示屏5。
本发明实施例所提供的一种可定向传声的智能手表，其采用定向扬声器3代替传统的扬声器，利用定向扬声器3定向传声的特点，让智能手表在通话时声音定向传播；并且出音孔2可朝向于斜上方设置，当定向扬声器3工作时，通过出音孔2产生一束可听声束7，用户只需要适当抬起手腕，将出音孔2对准耳朵的方向，即可完成正常通话或听歌等操作，非常安全方便，可以有效地解决通话隐私及噪音污染，且无需使用耳机来解决，不必时刻带着耳机，给用户带来良好的通话环境及体验，能够真正地解决问题。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换或改进等，均应包含在本发明的保护范围之内。
