技术领域
本发明涉及声音输出装置领域，具体涉及一种无线耳机以及应用于无线耳机中的整合触摸及天线结构的电子组件。
背景技术
目前，无线耳机，例如蓝牙耳机等，由于省去了耳机线，携带方便，且无需考虑耳机接口适配问题，应用越来越广泛。为了方便通过耳机对设备的控制，现有的部分无线耳机采用了触控传感器作为输入。然而，无线耳机通常较为小巧，内部空间十分有限，同时还要收纳电池、喇叭、主板、天线等无线耳机不可或缺的器件，触控传感器的引入将会较少其他其他器件的空间，引起结构和功能之间的干涉，特别是对天线的影响巨大。在一些设计中，为通过缩短天线尺寸来为触控传感器腾出空间，避免两者的干涉。然而，这样对天线性能造成了影响，导致了无线耳机传输性能的下降。
发明内容
本申请实施例提供了一种无线耳机及整合触摸及天线结构的电子组件，以解决上述问题。
一方面，提供一种无线耳机，所述无线耳机包括触摸感应单元以及天线体，所述天线体围绕所述触摸感应单元，且与所述触摸感应单元间隔设置，其中，所述天线体形成具有开口的环形结构。
另一方面，还提供一种整合触摸及天线结构的电子组件，所述电子组件包括触摸感应单元以及天线体，所述天线体围绕所述触摸感应单元，且与所述触摸感应单元间隔设置，其中，所述天线体形成具有开口的环形结构。
本申请中，通过天线体围绕所述触摸感应单元设置且形成具有开口的环形结构，能够保证天线体所需的尺寸/长度而保证天线性能，且能够减少无线耳机的整体尺寸，而通过与所述触摸感应单元间隔设置，能够避免天线体与触摸感应单元之间的干扰。因此，可在不增大无线耳机的体积的同时，整合触摸感应功能且确保天线体的性能不受到影响。

具体实施方式
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
请一并参阅图1及图2，图1为本申请一实施例中的无线耳机100的示意出内部结构的平面示意图，图2为本申请一实施例中的无线耳机100的内部结构的侧面示意图。如图1及图2所示，所述无线耳机100包括触摸感应单元1以及天线体2，所述天线体2围绕所述触摸感应单元1，且与所述触摸感应单元1间隔设置，其中，所述天线体2形成具有开口的环形结构。即，所述天线 体2形成的环形结构是不封闭的环形结构。
从而，本申请中，通过天线体2围绕所述触摸感应单元1设置且形成具有开口的环形结构，能够保证天线体2所需的尺寸/长度而保证天线性能，且能够减少无线耳机100的整体尺寸，而通过与所述触摸感应单元1间隔设置，能够避免天线体2与触摸感应单元1之间的干扰。因此，可在不增大无线耳机100的体积的同时，整合触摸感应功能且确保天线体100的性能不受到影响。
如图1所示，所述触摸感应单元1包括至少两个触摸感应片11，所述至少两个触摸感应片11沿着预设方向间隔排列，即，所述至少两个触摸感应片11为沿着同一个方向排列且相互间隔的。所述天线体2包括第一天线段21、第二天线段22以及第三天线段23，所述第一天线段21位于所述两个触摸感应片11的一侧，所述第三天线段23设置于所述至少两个触摸感应片11的另一侧，所述第二天线段22连接所述第一天线段21和第三天线段23。具体的，所述天线体2在所述两个触摸感应片11的一侧沿着第一方向延伸形成所述第一天线段21，并在延伸经过所有触摸感应片11后弯曲延伸至所述至少两个触摸感应片11的另一侧形成所述第二天线段22后，沿着第二方向延伸预设长度形成所述第三天线段23，所述第二方向与所述第一方向与所述至少两个触摸感应片11的排列方向即所述预设方向平行，且所述第二方向与所述第一方向的方向相反。
其中，本申请中，所述“间隔”的意思为两个元件之间具有间距，例如，所述天线体2围绕所述触摸感应单元1，且与所述触摸感应单元1间隔设置指的是：所述天线体2围绕所述触摸感应单元1，且与所述触摸感应单元1具有间距，两者不接触或不具有重叠区间。
即，所述触摸感应单元1包括至少两个间隔排列的触摸感应片11，所述天线体2包括了第一天线段21、第二天线段22以及第三天线段23，所述第一天线段21沿着至少两个触摸感应片11的排列方向延伸，且延伸经过所有的触摸感应片11。然后，从所述第一天线段21的经过所有触摸感应片11的末端进一步弯曲延伸形成第二天线段22。所述第二天线段22在延伸至所述至少两个触摸感应片11的另一侧后，从所述第二天线段22延伸至另一侧的末端朝着第二方向延伸预设长度形成第三天线段23。
从而，所述天线体2形成围绕触摸感应单元1的具有开口的环形结构。
其中，所述第三天线段23的长度小于所述第一天线段21的长度。具体的，如图1所示，所述三天线段23仅延伸经过一个触摸感应单元1。从而，所述至少两个触摸感应片11的另一侧至少部分位置未设置所述第三天线段23，而形成所述天线体2的开口。
其中，本申请的无线耳机100可支持蓝牙无线通信，通过第二天线段22以及所述第三天线段23延伸预设长度，可保证整个天线体2可在蓝牙2.4GHz频段正常工作，且所述三天线段23延伸的预设长度显著小于第一天线段21的长度，从而，不会导致左右两边导体上的反向电流辐射场相互抵消，降低天线性能。因此，所述第三天线段23的预设长度可预先根据满足无线通信需求，且不会导致降低天线性能的要求进行设计。
在一些实施例中，如图1所示，所述第一天线段21以及第三天线段23为直线段，所述第二天线段22为弧形段。
显然，在其他实施例中，所述第一天线段21以及第三天线段23也可为带有一些弧度的曲线段，或者可为波浪形状，以增大天线体2的长度，所述第二天线段22也可为折线段，等等。
如图1所示，所述无线耳机100还包括耳机柄3以及设置在耳机柄3一端的听筒4，所述至少两个触摸感应片11以及天线体2设置于所述耳机柄3中，所述至少两个触摸感应片11的排列方向(即所述预设方向)、所述第一方向以及所述第二方向与所述耳机柄3的长度方向平行，所述第一方向为从远离所述听筒4到靠近所述听筒4的方向，所述第二方向为从靠近所述听筒4至远离所述听筒4的方向。
即，如图1所示，所述至少两个触摸感应片11沿着耳机柄3的长度方向依次间隔排列，所述第一天线段21大致可从最远离听筒4的触摸感应片11的位置开始朝向听筒4延伸，然后，在经过最靠近听筒4的触摸感应片11后，朝着至少两个触摸感应片11的另一侧弯曲延伸形成所述第二天线段22，然后，再朝远离听筒4的方向延伸，形成所述第三天线段23。
其中，所述耳机柄3与听筒4固定的一端整体也为弧形设计，所述第二天线段22的弯曲弧度可与所述耳机柄3与所述听筒4固定的一端的弯曲弧度相 同。
如图1及图2所示，所述第三天线段23的对应最靠近所述听筒4的触摸感应片11的区域中设置有天线馈电点F1。所述最靠近听筒4的触摸感应片11也为与所述第三天线段23大致对应的位于最端部的触摸感应片11。即，所述第三天线段23的对应最端部的触摸感应片11的区域中设置有天线馈电点F1。
进一步的说，本申请中，所述天线体2的用于连接馈源的天线馈电点F1是位于所述第三天线段23中的某一位置，且具体为位于所述第三天线段23中对应最靠近所述听筒4的触摸感应片11的区域中的某一位置。
如图1及图2所示，所述所述无线耳机100还包括承载板5，所述耳机柄3包括耳机柄壳体31，所述至少两个触摸感应片11以及所述天线体2设置于所述承载板5上，所述至少两个触摸感应片11、所述天线体2以及所述承载板5均收容于耳机柄壳体31形成的收容空间中，且所述承载板5靠近所述耳机柄壳体31的内表面。
即，本申请中，所述至少两个触摸感应片11以及所述天线体2均为设置于所述承载板5上，且所述承载板5靠近所述耳机柄壳体31的内表面，而方便用户从所述耳机柄壳体31的外表面对至少两个触摸感应片11进行触摸。即，所述承载板5靠近耳机柄壳体31某一侧的壳体内表面的，从而用户通过手指触摸所述耳机柄壳体31的对应侧的外表面时，手指与所述承载板5的距离将比较小，而可以提高触摸灵敏度。
其中，在一些实施例中，所述耳机柄壳体31为绝缘材料制成，例如，为塑料、塑胶等材料制成。所述触摸感应单元1为电容式触摸感应单元，所述至少两个触摸感应片11为电容式触摸感应电极片，由于所述承载板5靠近所述耳机柄壳体31的内表面，当用户的手指触摸所述耳机柄壳体31外表面的对应某一触摸感应片11的位置时，用户的手指与所述触摸感应片11将发生电容耦合而使得所述触摸感应片11产生触摸感应信号。而由于所述耳机柄壳体31为绝缘材料制成，也不会对天线体2的性能造成影响。
其中，所述耳机柄壳体31的一侧的外表面可设置有输入指示标记，例如设置有触摸指示图案，提示用户从该侧进行触摸输入。所述承载板5具体为靠近耳机柄壳体31设置有输入指示标记的一侧的壳体内表面。其中，所述耳机 柄壳体31的外表面指的是壳体外侧表面，即，可被用户观看以及接触的表面，所述耳机柄壳体31的内表面指的是与所述耳机柄壳体31的外表面相对的表面，即与耳机柄壳体31内的元件正对的表面。
在一些实施例中，所述至少两个触摸感应片11以及所述天线体2均设置于所述承载板5的靠近所述耳机柄壳体31的表面。即，在一些实施例中，所述至少两个触摸感应片11以及所述天线体2设置在所述承载板5的同一表面，且具体的为设置在承载板5的靠近/朝向所述耳机柄壳体31的表面。其中，所述承载板5的靠近/朝向所述耳机柄壳体31的表面具体为靠近/朝向所述耳机柄壳体31的设置有输入指示标记的一侧的表面。因此，所述至少两个触摸感应片11以及所述天线体2都能更加靠近所述耳机柄壳体31的设置有输入指示标记的一侧，而使得触摸感应和天线辐射的性能都为较佳。
其中，在一些实施例中，所述至少两个触摸感应片11可进一步间隔设置在一绝缘板(图中未标号)上，与所述绝缘板构成所述触摸感应单元1，然后再设置在所述承载板5上。显然，所述绝缘板也可忽略，所述承载板5用于设置所述至少两个触摸感应片11以及所述天线体2的区域均为绝缘区域。
请参阅图3，为其他实施例中的触摸感应单元1和天线体2设置于承载板5上的示意图。其中，所述承载板5包括两个相对的表面，在另一实施例中，所述至少两个触摸感应片11以及所述天线体2可分别设置于所述承载板5的两个相对表面。
例如，所述天线体2可设置于所述承载板5的靠近/朝向所述耳机柄壳体31的表面，即，所述承载板5的靠近/朝向所述耳机柄壳体31的设置有输入指示标记的一侧的表面，而所述至少两个触摸感应片11则设置于所述承载板5的背离所述耳机柄壳体31的表面，即所述承载板5的远离所述耳机柄壳体31的设置有输入指示标记的一侧的表面。由于所述承载板5整体为靠近所述耳机柄壳体31的内表面设置，即靠近所述耳机柄壳体31的设置有输入指示标记的一侧的内表面设置，从而，即使所述至少两个触摸感应片11设置于所述承载板5的背离所述耳机柄壳体31的表面，所述至少两个触摸感应片11仍然与所述耳机柄壳体31相距很近，满足与用户手指进行电容耦合的灵敏度要求。
显然，在一些实施例中，也可为所述至少两个触摸感应片11设置于所述 承载板5的靠近/朝向所述耳机柄壳体31的表面，而所述天线体2则可设置于所述承载板5的背离所述耳机柄壳体31的表面。
其中，所述至少两个触摸感应片11以及所述天线体2分别设置于所述承载板5的两个相对表面时，所述至少两个触摸感应片11在所述承载板5上的投影被所述天线体2在所述承载板5上的投影包围，且所述至少两个触摸感应片11在所述承载板5上的投影与所述天线体2在所述承载板5上的投影不重叠。即，前述的所述天线体2围绕所述触摸感应单元1，还可包括所述所述至少两个触摸感应片11在所述承载板5上的投影被所述天线体2在所述承载板5上的投影围绕。
如图2所示，在一些实施例中，所述耳机柄3还包括耳机柄支架32，所述耳机柄支架32位于所述耳机柄壳体31内，设置有所述至少两个触摸感应片11以及所述天线体2的承载板5位于所述耳机柄支架32上，且靠近所述耳机柄壳体31的内表面。
如图2所示，所述无线耳机100还包括电路板6以及设置于电路板6上的控制器7以及射频电路8，所述至少两个触摸感应片11分别通过对应的电连接件J1与所述控制器7连接，而用于实现触摸感应功能，所述天线体的天线馈电点F1通过射频连接件J2与所述射频电路8连接，而用于实现天线射频信号的收发。
其中，所述电连接件J1可为FPC(Flexible printed circuit，柔性电路)板、传导线等，所述射频连接件J2可为馈电弹片，也可为FPC板、传导线等等。
其中，当用户的手指触摸所述耳机柄壳体31外表面的对应某一触摸感应片11的位置时，用户的手指与所述触摸感应片11将发生电容耦合而使得所述触摸感应片11产生触摸感应信号，所述控制器7用于接收所述触摸感应信号。
其中，当用户的手指在耳机柄壳体31外表面对应所述至少两个触摸感应片11的区域沿着耳机柄的长度方向，也即所述至少两个触摸感应片11的排列方向滑动时，则所述至少两个触摸感应片11将会先后产生触摸感应信号。所述控制器7将先后接收不同的触摸感应片11产生的触摸感应信号，而根据所述先后接收的触摸感应信号确定用户的滑动方向，并执行相应的功能/操作。
例如，当确定用户的滑动方向为在耳机柄壳体31从上至下滑动，即，从 靠近听筒4到远离听筒4的方向滑动时，则可控制执行音量减小操作，当确定用户的滑动方向为在耳机柄壳体31从下至上滑动时，即，从远离听筒4到靠近听筒4的方向滑动时，则可控制执行音量减小操作，等等。
其中，所述控制器7可包括多个引脚，每一引脚通过对应的电连接件J1与对应的触摸感应片11连接，且每一引脚与其所连接的触摸感应片11形成对应关系。所述控制器7根据接收到所述触摸感应信号的引脚，而可确定出当前产生所述触摸感应信号的触摸感应片11，从而，根据先后接收的触摸感应信号的引脚，而可确定出先后产生所述触摸感应信号的触摸感应片11，而可以进一步确定用户触摸该些触摸感应片11的次序，而可得出用户的滑动方向。
在一些实施例中，所述控制器7在预设时间内(例如2秒内)仅接收到某一个触摸感应信号时，确定发生的为单击操作，而根据接收到所述触摸感应信号的引脚，而可确定出当前产生所述触摸感应信号的触摸感应片11，并根据预设的单个触摸感应片11与功能操作的对应关系，执行对应的功能。
例如，所述控制器7在预设时间内仅接收到最顶端的触摸感应片11，即，最靠近听筒4的触摸感应片11产生的触摸感应信号时，控制执行切换到上一首的操作，所述控制器7在预设时间内仅接收到最底端的触摸感应片11，即，最远离听筒4的触摸感应片11产生的触摸感应信号时，控制执行切换到下一首的操作，等等。
其中，滑动触摸和单击触摸的对应操作并不限于以上举例。
其中，所述射频电路8可包括射频源(图中未示)和匹配电路(图中未示)，所述射频源依次通过匹配电路以及射频连接件J2与所述天线体2的天线馈电点F1连接，为所述天线体2提供馈电信号。
在一些实施例中，每一连接于触摸感应片11的电连接件J1还串联有一高频电感，每一触摸感应片11分别通过对应的串联有高频电感的电连接件J1与所述控制器7连接。其中，高频电感指的是只对高频交变电流起阻碍作用的电感，又叫高频扼流圈。
从而，每一触摸感应片11通过串联有高频电感的电连接件J1与所述控制器7连接，可以阻断天线体2耦合到触摸感应片11的感应电流回流的通路，减少对天线体2的耦合效应。
其中，如图2所示，所述耳机柄支架32将所述耳机柄壳体31的收容空间大致分隔成第一收容空间S1和第二收容空间S2，所述承载板5以及所述电路板6分别设置于所述耳机柄支架32的两侧，而分别位于所述第一收容空间S1和第二收容空间S2内。
在一些实施例中，所述承载板5与所述电路板6平行设置，且所述承载板5与所述电路板6的距离为预设距离。
在一些实施例中，所述预设距离可为1.9mm(毫米)。从而，通过所述承载板5与所述电路板6的距离设置为预设距离，例如为1.9mm，能够使得天线体2的馈电路径满足要求。
在一些实施例中，所述承载板5为FPC板(柔性电路板)，所述承载板5固定于所述耳机柄支架32的一侧表面。
在另一些实施例中，所述承载板5与所述耳机柄支架32可为一体式结构，即，所述承载板5可为所述耳机柄支架32的一部分。
在一些实施例中，所述天线体2可为通过通过激光镭射技术在承载板5的上形成的LDS天线。其中，LDS天线指的是通过激光镭射技术，直接在设置于所述承载板5镀上的金属天线图案。
在一些实施例中，如图1所示，所述天线体2还包括弯折状的第四天线段24，所述第四天线段24连接于所述第一天线段21的远离所述第二天线段22的端部。其中，所述第四天线段24可为所述第二天线段21的远离所述第二天线段22的端部弯折延伸形成。
其中，如图1所示，所述第一天线段21的远离所述第二天线段22的端部向至少两个触摸感应片11的另一侧延伸第一距离后，再朝着第二方向延伸第二距离，而形成一个“L”形的第四天线段24。
其中，所述第一距离小于所述触摸感应片11的宽度。其中，所述触摸感应片11的宽度指的所述触摸感应片11垂直于至少两个触摸感应片11的排列方向上的尺寸。
从而，所述天线体2在耳机柄3远离听筒4的端部对所述触摸感应单元1进行部分包围。
在一些实施例中，每一触摸感应片11的宽度可为1mm，每一触摸感应片 11的长度可根据需要设计。其中，所述触摸感应片11的长度可为平行于至少两个触摸感应片11的排列方向的尺寸。
其中，所述至少两个触摸感应片11的长度可均相同。在其他实施例中，所述至少两个触摸感应片11的长度可均不同，或者至少部分触摸感应片11的长度不同。
其中，所述无线耳机100还包括设置于所述耳机柄3远离听筒4端部的充电接口9。
所述第一天线段21的远离所述第二天线段22的端部，也即靠近所述充电接口9的端部。通过在所述第一天线段21的远离所述第二天线段22的端部，即靠近所述充电接口9的端部延伸形成有弯折状的第四天线段24，可以减小充电接口9中的充电引脚的耦合效应，提升辐射效率。

其中，所述第五天线段25可为直线段。通过该结构，可以进一步提升天线性能。
