Description

耳塞式装置及电子装置 技术领域
本申请实施例涉及生物特征检测技术领域，尤其涉及一种耳塞式装置及电子装置。
背景技术
智能产品的快速发展，比如智能耳机的出现，方便了保健性功能应用的实现，比如可实现心率、血氧等生物特征的检测。具体的应用场景比如在运动时对心率、血氧进行监控以判断运动过程中用户的生物特征是否正常，或者，在睡眠时对心率、血氧进行监控以判断睡眠过程中用户的生物特征是否正常。
对于智能产品上述保健型应用功能的实现，目前常用的方式为：基于光学原理进行生物特征的测量，比如光线反射原理、光线透射原理。以光线反射原理为例：光线发射器入射到生物组织后被反射，光线接收器接收到反射的光线，基于反射的光线进行生物特征的检测。在此过程中，经过组织中血液会对入射光线进行吸收、散射等处理后，再形成射向光线接收器的反射光线。由于组织中血液会发生周期性变化，由此导致反射光线也会发生变化，据此通过对反射光线进行感应、分析，从而得到生物特征。类似，对于光线透射原理来说，基于透射的光线进行感应、分析，从而得到生物特征。
现有技术中，比如如果将生物特征检测功能与耳机结合实现生物特征的检测时，耳机的整体尺寸较大，且佩戴的舒适性较差。

为了与耳机已有结构密切结合，尽可能减小耳机的整体体积，本申请实施例中，耳塞式装置中的生物特征检测模组被设置为与所述外耳道道和耳洞口围合的区域适配，所述外耳道和耳洞口围合的区域作为探测面。具体地，比如生物特征检测模组与外耳道适配(如贴合)，或者，生物特征检测模组与外耳道连接的如下区域适配：耳屏内侧区域,或者，耳甲腔区域,或者,耳屏上切迹区域,或者,耳屏间切迹区域。参见图2所示，D所示即为所述外耳道和耳洞口围合的区域。
图3为本申请实施例三中耳塞式装置的结构示意图；如图3所示，如前 所述，以入耳式耳机实现上述耳塞式装置时，即所述耳塞式装置包括声音传导腔体，所述生物特征检测模组位于所述声音传导腔体的外壁(图3中未示出)。具体地，生物特征检测模组中的所述光线发射单元101和所述光线接收单元102设置在所述声音传导腔体外壁的外表面，从而进一步缩小整个入耳式耳机的整体体积，并便于舒服地佩戴。
本实施例中，在具体实现时，声音传导腔体可以为圆柱体，或者为棱柱体，对应地，所述声音传导腔体外壁整体形状可以呈圆柱体或者棱柱体。
进一步，本实施例中，所述声音传导腔体外壁外围还设置有入耳式耳套，入耳式耳套包裹声音传导腔体外壁。入耳式耳套可以由硅胶、软橡胶等材质制成，在佩戴时入耳式耳塞可与耳朵的内表面形成挤压，从而方便入耳式耳机的稳固佩戴。

在一具体应用场景中，佩戴辅助机构103与耳塞式装置之间可以可拆卸，以便在需要进行生物特征检测时将佩戴辅助机构103装配到耳塞式装置上，而在不需要进行生物特征检测时，将佩戴辅助机构103从耳塞式装置上拆卸下来，从而方便耳机和佩戴辅助机构103的灵活使用。佩戴辅助机构103可以是耳塞式装置的结构件，也可以不是耳塞式装置的结构件，而是作为耳塞式装置的配件。
图4为本申请实施例四中光线发射单元以及光线接收单元的设置示意图；如图4所示，耳塞式装置还可以包括：第一基板104、第二基板105、柔性部件106、导光单元107，所述光线发射单元101设置在所述第一基板104上，所述光线接收单元102设置在所述第二基板105上。本实施例中，所述第一基板104和所述第二基板105均为刚性基板。

需要说明的是，在其他实施例中，可替代地，所述光线发射单元101和所述光线接收单元102也可以设置在同一块刚性基板或者柔性基板上，或者分别设置在一块柔性基板上，或者，所述第一基板和所述第二基板中之一为柔性基板或者两者均为柔性基板。进一步地，柔性部分可以为柔性基板的部分结构。
本实施例中，所述光线发射单元101近似为柱光源，所述光线接收单元102近似为平面阵列，以尽可能以较大的光线感应面积接收光线。
本实施例中，所述光线发射单元101和所述光线接收单元102之间通过所述柔性部件106连接，所述柔性部件用于调整所述光线发射单元101和所述光线接收单元102之间的相对位置和/或相对角度。

可选地，在一具体应用场景中，所述光线发射单元101和所述光线接收单元102朝向所述围合的区域的外表面的法线之间的夹角大于等于0度，但不超过180度。当大于0度，不超过180度时，一方面可以较好的适配耳朵的外耳道与耳洞口围合的区域，另外一方面，还可以增加光线发射单元101发射的光线在耳朵组织里面的作用距离，避免过多的光线被耳朵内表面反射后直接射向光线接收单元102，从而进一步提高了生物特征检测的准确度。
本实施例中，所述导光单元107用于引导所述光线发射单元101发射出的光线到达所述探测面，和/或，用于引导被所述耳朵组织处理后的光线到达所述光线接收单元102。具体地，可以针对光线发射单元101、光线接收单元102上均设置一导光单元107，即包括两个导光单元107，这两个导光单元107可以为一体结构或者分体结构，即所述光线发射单元101上的导光单元107与所述光线接收单元102上的导光单元107为一体结构或者分体结构。但是，需要说明的是，也可以仅针对光线发射单元101或者光线接收单元102设置一导光单元107，即包括一个导光单元107。本实施例中，导光单元107的存在，提高了光线传输的效率，降低了装置的整体功耗。
在另一实施例中，可替代地，也可以参照导光单元107的设置方式设置透光通道。
在一具体应用场景中，导光单元107可以略突出于耳机外壳的情形，以与耳朵的探测面紧密贴合，从而提高光线传输的效率，增加信噪比，另外，降低耳塞式装置整机的功耗。
本实施例中，所述导光单元107朝向探测面的表面形状设置成与所述耳朵的探测面匹配。如果探测面为平面，则所述导光单元107朝向探测面的表面为平面； 如果探测面为弧形面，则所述导光单元107朝向探测面的表面为弧形面；如果探测面为不规则的曲面，则所述导光单元107朝向探测面的表面同样为不规则的曲面。需要说明的是，可以根据结构设计的需要，仅将所述导光单元107朝向探测面的表面形状设置成与所述探测面匹配，比如导光单元107的材质为弹性材料即可实现导光单元107与任意形状的所述探测面匹配。
本实施例中，若导光单元107朝向探测面的表面近似为弧形，以与耳屏内侧区域尽可能地无缝贴合，从而提高光线传输的效率。另外，由于柔性部件106的存在，使得导光单元107与探测面的贴合位置可以灵活调整。
上述图4的实施例中，还包括第一遮光单元108A，所述第一遮光单元108A分别位于所述光线发射单元101和所述光线接收单元102的上方，用于以避免所述光线发射单元101发射出的光线未经所述耳朵的组织处理后直接到达所述光线接收单元102，进而提高生物特征检测的准确度，所述第一遮光单元108A具体可以设置在导光单元107上方。另外，为了光线发射单元101发射的光线、被耳朵的组织处理的光线能射向所述光线接收单元102，在所述第一遮光单元108A上设置有可使光线可穿过通孔。
图5为本申请实施例五中光线发射单元和光线接收单元的设置示意图；如图5所示，耳塞式装置还可以包括：第二遮光单元108B、遮光层109以及为所述光线发射单元101和所述光线接收单元102中至少之一配置的保护盖板110。
当包括上述导光部件时，上述导光部件同时作为保护盖板110或者保护盖板同时作为导光部件，从而将进一步减小了入耳式耳机的体积，使得入耳式耳机的整体结构较为紧凑。
本实施例中，所述第二遮光单元108B用于阻挡所述光线发射单元发射的光线未经耳朵的组织处理直接射向所述光线接收单元，具体地，比如通过遮挡或者吸收所述光线发射单元101发射出的光线，以避免所述光线发射单元101发射出的光线未经所述耳朵的组织处理后直接到达所述光线接收单元102，进 而提高生物特征检测的准确度。
本实施例中，所述第二遮光单元108B具体设置在所述光线发射单元101和所述光线接收单元102之间。
在一具体应用场景中，所述第二遮光单元108B与所述声音传导腔体的外壁元为一体结构，或者，所述第二遮光单元108B与所述光线发射单元101以及所述光线接收单元102为一体结构。
具体实施时，保护盖板110同时复用为导光单元时，可以略突出于耳机外壳的情形，以与耳朵的探测面紧密贴合，从而提高光线传输的效率，增加信噪比，另外，降低耳塞式装置整机的功耗。
所述遮光层109设置在所述保护盖板110的上方，具体地，比如在所述保护盖板110的上表面或者下表面，或者，在所述保护盖板110的上表面和下表面。所述遮光层109用于阻挡所述光线发射单元101发射的光线未经所述耳朵处理直接射向所述光线接收单元102，从而提高心率特征检测准确度。遮光层109的面积可以根据需求灵活设置，遮光层109在保护盖板110上的位置可以根据实际需求灵活选择，只要可以提高心率特征检测准确度即可。
在一具体应用场景中，所述遮光层为油墨层、胶水层、吸光镀膜层中的至少任一一种。

本实施例中，参照所述光线发射单元101和光线接收单元102在所述声音传导腔体外壁111上的设置位置，在所述入耳式耳套100对应的位置形成通孔，所述通孔作为所述透光通道112(或者，在所述通孔中安装导光管，所述导光管作为所述导光单元)。
本实施例中，为入耳式耳机还配置有防尘网113。
当在所述通孔中安装导光管时，所述导光管和所述入耳式耳套通过双色注塑做形成一体结构；或者，通过将所述导光管安装在所述入耳式耳套上形成分体结构。
另外，本实施例中，入耳式耳套100由于可以由弹性材料如硅胶、软橡胶等支撑，当佩戴时，可以通过挤压与耳朵内表面的皮肤紧密接触，从而防止在运动过程中，光线发射单元101和光线接收单元102与所述探测面的相互位置发生滑动，进一步提高了生物特征检测准确度。
另外，在一具体应用场景中，还可以通过一固定结构114将光线发射单元101和光线接收单元102设置在所述声音传导腔体外壁111上。具体地，可以通过将所述声音传导腔体外壁111设置生物特征检测模组的位置处做切面，使其具有一定的平整度，再将固定结构设置在所述切面上。

上述包括柔性部件的实施例中，由于柔性部件的存在，可以任意调整光线发射单元和光线接收单元之间的相对位置、相对角度，从而使得耳塞式装置整体上可以适用于任意形状的探测面。
在上述实施例中，即使在运动过程中，由于光线发射单元101和/或光线接收单元102设置在声音传导腔体的外壁上或者入耳式耳塞上，可以防止耳塞式装置与探测面之间发生相对滑动，从而提高了检测信号的稳定性和强度，与此同时减弱或者消除了运动对检测信息号信噪比的负面影响。
