下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本申请一部分实施例，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。
下面结合附图具体描述根据本申请实施例的智能眼镜100。
如图1至图9所示，根据本申请实施例的智能眼镜100包括镜框10、镜腿20、第一发声单元30、活动件40和第二发声单元50。
具体而言，镜腿20的第一端与镜框10连接，镜腿20的预定位置处设有腔室，镜腿20设有与腔室连通的第一出声孔23和至少一个第二出声孔24。第一发声单元30设于腔室，第一发声单元30将腔室分隔为第一腔21和第二腔22，第一出声孔23与第一腔21连通，第二出声孔24与第二腔22连通。活动件40与镜腿20可活动地连接，第二发声单元50设于活动件40。其中，活动件40包括第一位置和第二位置，在活动件40处于第一位置时，活动件40相对于镜腿20展开，第二发声单元50与镜腿20的第一端之间距离为第一距离，活动件40处于第二位置时，第二发声单元50与镜腿20的第一端之间的距离为第二距离，其中，第一距离大于第二距离。
换言之，如图1和图2所示，根据本申请实施例的智能眼镜100主要由镜框10、镜腿20、第一发声单元30、活动件40和第二发声单元50组 成。其中，镜腿20的第一端安装在镜框10上，镜腿20的靠近第二端的位置设置有腔室，参见图3，镜腿20可以设置有与腔室连通的第一出声孔23和至少一个第二出声孔24。第二出声孔24可以是一个或者多个，第二出声孔24的具体个数以及孔径大小可以根据第一出声孔23的位置进行具体设定。
镜腿20的第一端和第二端为镜腿20的长度方向的两端。第一发声单元30设置在腔室中，第一发声单元30可以将腔室分隔为第一腔21和第二腔22。第一出声孔23可以与第一腔21连通，第二出声孔24可以与第二腔22连通。在本申请中，智能眼镜100佩戴后，指向人耳的前腔可以为第一腔21，第一发声单元30后部的后腔可以作为第二腔22，第一出声孔23与第一腔21连通可以作为前腔出声孔，第二出声孔24与后腔连通可以作为后腔泄声孔。
第一发声单元30和第二发声单元50可以向用户辐射不同的音频信号，能够提供更加丰富的声学体验。
一些实施例中，第一发声单元30与第二发声单元50分别接收中低频信号和中高频信号并发出声音，保证第二发声单元50较低的响度就能满足佩戴者听感需求，使智能眼镜100在有效频段内大大提升远场私密性，且不影响近耳听感，有效提升用户体验。在活动件40处于第二位置时，第二发声单元50与镜腿20的第一端之间具有第二距离，通过第一发声单元30接收全频电信号并发出声音，并通过第一发声单元30的第一出声孔23和第二出声孔24传播的声波在远场进行抵消，保证用户隐私。
需要说明的是，在本申请中，智能眼镜100的镜腿20为两个，每个镜腿20上可以均设置有腔室、第一出声孔23、第二出声孔24和第一发声单元30。每个镜腿20上也可以均设置有活动件40，在本申请中不再详细赘述。第二出声孔24(后腔泄声孔)的具体位置可以根据第一出声孔23(前腔出声孔)的位置来确定。通过设置第二出声孔24,所有第二出声孔24(后腔泄声孔)与第一出声孔23配合，利用偶极子原理，提高第一发声单元30所覆盖的中低频的远场私密性，使各方向私密性都较佳。
在本申请的一些具体实施方式中，镜腿20包括内侧面、外侧面、上 侧面及下侧面，其中，第一出声孔23可以位于镜腿20的下侧面，第二出声孔24可以位于镜腿20的上侧面。当然，第一出声孔23可以位于镜腿20的下侧面，第二出声孔24可以位于镜腿20的上侧面和外侧面。当一个第二出声孔24的声波与第一出声孔23的声波即可实现抵消时，只需要在一个镜腿20上设置一个与第一出声孔23位置相对应的第二出声孔24(镜腿20的上侧面)即可。
为抵消第一出声孔23的声波，可以在镜腿20上设置多个第二出声孔24(镜腿20的上侧面和外侧面)，其中一个第二出声孔24为主出声孔(如图3中所示)，镜腿20的侧面靠近该主出声孔的位置还可以设置有一个或者多个第二出声孔24作为辅出声孔(如图4和图5所示)，多个第二出声孔24彼此连通，辅出声孔可以作为一个较小的后腔泄声孔。辅出声孔的具体个数以及形状可以根据实际结构进行选择，在本申请中不再详细赘述。
根据偶极子声学原理，智能眼镜100佩戴后，指向人耳的前腔为第一腔21，第一发声单元30后部的后腔作为第二腔22，第一出声孔23与第一腔21连通作为前腔出声孔，第二出声孔24与后腔连通作为后腔泄声孔，前腔出声孔和后腔泄声孔传播的声波可以在远场进行抵消(参见图9)。当然，偶极子声学原理对于本领域技术人员来说是可以理解并且能够实现的，在本申请中不再详细赘述。
活动件40与镜腿20可活动地连接，如图4至图6所示，第二发声单元50设置在活动件40上。活动件40包括第一位置和第二位置，活动件40在第一位置和第二位置之间可切换，在活动件40处于第一位置时，如图1所示，活动件40可以相对于镜腿20展开，活动件40在展开后，第二发声单元50与镜腿20的第一端之间的距离为第一距离，第二发声单元50靠近镜腿20的第二端，并且使第二发声单元50靠近人耳耳孔处，保证人耳处于有效听音区域。第一发声单元30与第二发声单元50可以分别接收智能眼镜100发送的中低频信号和中高频信号，并且在第一发声单元30与第二发声单元50分别接到中低频信号和中高频信号后发出声音，保证智能眼镜100有效提升远场私密性，且不影响近耳听感，有效提升用户体 验。在活动件40处于第二位置时，如图2所示，第二发声单元50与镜腿20第一端之间的距离为第二距离，此时，活动件40处于收起状态，第二发声单元50远离镜腿20的第二端，通过第一发声单元30接收智能眼镜100发送的全频电信号并发出声音，并通过第一发声单元30的第一出声孔23和第二出声孔24传播的声波在远场进行抵消，保证用户隐私。
在本申请中，第一距离可以理解为活动件40上的第二发声单元50与镜腿20的第一端之间的直线距离。
需要说明的是，第二发声单元50在活动件40活动至第二位置时，第二发声单元50的正面和反面可以分别发出近似大小相等、相位相反的声波。其中第二发声单元50的正面可以是背向活动件40的一面，第二发声单元50的反面可以是朝向活动件40的一面。根据偶极子声学原理，大小相等、相位相反的声波会在远场相互抵消，形成消音区域，同时在靠近第二发声单元50的小部分区域(例如：人耳耳孔处)存在有效听音区域，实现远场消声，有效提高智能眼镜100的远场私密性，提升用户使用体验。
由此，根据本申请实施例的智能眼镜100，通过在镜腿20上设置活动件40，活动件40在第一位置和第二位置之间可切换，在活动件40处于第一位置时，活动件40相对于镜腿20展开，第二发声单元50靠近镜腿20的第二端，第二发声单元50靠近人耳，使人耳处于有效听音区域，第一发声单元30与第二发声单元50分别接收中低频信号和中高频信号并发出声音，保证第二发声单元50较低的响度就能满足佩戴者听感需求，使智能眼镜100有效提升远场私密性，且不影响近耳听感，有效提升用户体验。在活动件40处于第二位置时，活动件40收起，第二发声单元50远离镜腿20的第二端，通过第一发声单元30接收全频电信号并发出声音，并通过第一发声单元30的第一出声孔23和第二出声孔24传播的声波在远场进行抵消，保证用户隐私。
根据本申请的一个实施例，镜框10和镜腿20可以围成与人体头部适配的容纳部。活动件40具有第一侧和第二侧，活动件40位于第一位置时，活动件40的第一侧背离容纳部，活动件40的第二侧朝向容纳部，第二发声单元50可以固设于活动件40的第二侧的表面，保证活动件40第一位 置和第二位置之间活动时，第二发声单元50可以朝向人耳的耳孔，有效提高智能眼镜100的远场私密性，提升用户使用体验。
在本申请的一些具体实施方式中，活动件40处于第一位置时，智能眼镜100发送的电信号分成第一频段信号和第二频段信号。智能眼镜100将发送的电信号通过分频器分成第一频段信号和第二频段信号。其中，第一频段信号传送至镜腿20上的第一发声单元30，第二频段信号传送至活动件40上的第二发声单元50。第一发声单元30和第二发声单元50分别用于接收第一频段信号和第二频段信号，并对应发出第一频段信号和第二频段信号。其中，第一频段信号的频率可以小于所述第二频段信号的频率。可选地，第一频段信号可以为中低频信号，第二频段信号可以为中高频信号。活动件40上的第二发声单元50对中高频信号具有相对更优的消声效果。第一发声单元30与第二发声单元50分别接收智能眼镜100发送的中低频信号和中高频信号，并且在第一发声单元30与第二发声单元50分别接到中低频信号和中高频信号后发出声音，保证智能眼镜100有效提升远场私密性，且不影响近耳听感，有效提升用户体验。
活动件40处于第二位置时，活动件40收起，智能眼镜100发送的信号转换为全频信号。此时，第一发声单元用于接收全频信号并对应发出全频信号。通过镜腿20上第一发声单元30的第一出声孔23和第二出声孔24传播的声波在远场进行抵消，保证用户隐私。
具体来说，参见图4至图6，在活动件40处于第一位置时，活动件40相对镜腿20展开，活动件40上的第二发声单元50位于靠近人耳耳孔处。此时，智能眼镜100发出的全频信号通过分频技术，将全频电信号分为第一频段信号和第二频段信号，其中，智能眼镜100可以将第一频段信号传送至镜腿20上的第一发声单元30，第一发声单元30接收第一频段信号并发出声音。智能眼镜100将第二频段信号传送至活动件40上的第二发声单元50，第二发声单元50接收第二频段信号并发出声音。
需要说明的是，在本申请中，通过分频技术可以将全频电信号分成第一频段信号和第二频段信号，其中，第一频段信号可以为中低频信号，第二频段信号可以为中高频信号，第一发声单元30可以采用中低频喇叭， 第二发声单元50可以采用中高频喇叭。本申请的智能眼镜100中的分频技术所的具体分频点，可以根据第一发声单元30和第二发声单元50所能够达到的远场私密性的有效频段进行具体确定。当第一发声单元30和第二发声单元50的远场私密性的有效频段改变时，分频点也随之改变，第一频段信号和第二频段信号的频段范围也发生变化。
在本申请中，通过高低分频技术和声学结构(声学结构包括第一发声单元30、第二发声单元50、第一腔21、第二腔22、第一出声孔23和第二出声孔24等)可以在有效频段内大大提升智能眼镜100的远场私密性且不影响近耳听感。本申请的智能眼镜100通过分频技术与第一发声单元30和第二发声单元50的组合能够将远场私密性的有效频段提高至10K左右。当然，对于本领域技术人员来说，分频技术和具体的分频原理是可以理解并且能够实现的，在本申请中不再详细赘述。
根据本申请的一个实施例，如图3所示，第一出声孔23和第二出声孔24可以在竖直方向上的投影至少部分重合。优选地，第一出声孔23与第二出声孔24位于同一条直线上。智能眼镜100处于佩戴状态时，第二出声孔24(即负责抵消第一出声孔23声波的后腔泄声孔)应与第一出声孔23排布在一条竖直线上。当然，第一出声孔23和第二出声孔24的具体大小可以由需要的消音程度决定，通过设计第二出声孔24的个数和排布位置，可以用于调节后腔产生的高频峰与前腔产生的高频峰一致，避免出现比前腔高频峰频点低的后腔峰。因此，在本申请中，为尽量减少开孔数量，前、后腔的大小可以保持尽量一致，即第一腔21和第二腔22的大小可以一致。另外，另一些实施例中，第一出声孔23与第二出声孔24在竖直方向上的投影至少部分位于同一竖直面、其中该竖直面垂直于镜腿20。
在本申请的一些具体实施方式中，活动件40设于镜腿20的内表面，活动件40的第一侧靠近镜腿20，活动件40的第二侧背离镜腿20，第二发声单元50设于活动件40的第二侧。
换句话说，如图1和图2所示，活动件40可以设置在镜腿20的内表面，活动件40可以相对镜腿20的内表面可活动。其中，活动件40的第 一侧可以靠近镜腿20，活动件40的第二侧可以背离镜腿20，第二发声单元50可以设置在活动件40的第二侧。可选地，活动件40的第二侧可以设置有容纳腔41，容纳腔41可以背离镜腿20敞开，第二发声单元50可以设置在容纳腔41内。在活动件40活动至第一位置时，第二发声单元50的正面和反面可以发出近似大小相等、相位相反的声波。其中第二发声单元50的正面可以是背向活动件40的一面，第二发声单元50的反面可以是朝向活动件40的一面。根据偶极子声学原理，两列波会在远场相互抵消，形成消音区域，同时在靠近第二发声单元50的小部分区域(例如：人耳耳孔处)会不受反向波的影响，存在有效听音区域，实现远场消声，有效提高智能眼镜100的远场私密性，提升用户使用体验。
根据本申请的一个实施例，活动件40为长形片体，活动件40的第一端与镜腿20活动连接，活动件40的第二端绕活动件40的第一端可活动，第二发声单元50设于活动件40的第二端，活动件40处于第一位置时，活动件40的第二端靠近镜腿20的第二端，活动件40处于第二位置时，活动件40的第一侧与镜腿20的内表面贴合。
也就是说，参见图7和图8，活动件40可以大致设置成长形片体，活动件40的第一端可以与镜腿20活动连接，活动件40的第二端绕活动件40的第一端可活动。活动件40的第一端和第二端可以为活动件40的长度方向的两端。第二发声单元50设置在活动件40的第二端。在活动件40处于第一位置时，活动件40相对镜腿20展开，活动件40的第二端靠近镜腿20的第二端，使第二发声单元50靠近人耳耳孔处，保证人耳处于有效听音区域。第一发声单元30可以接收第一频段信号，第二发声单元50可以接收第二频段信号，并且在第一发声单元30与第二发声单元50分别接到第一频段信号和第二频段信号后发出声音，保证智能眼镜100有效提升远场私密性，且不影响近耳听感，有效提升用户体验。当然，活动件40也可以收纳在镜腿20内，如图5所示，活动件40处于第一位置时，活动件40的第二端靠近镜腿20的第二端。活动件40处于第二位置时，活动件40收纳在镜腿20内(如图2所示)。
在本申请中，第二发声单元50可以选取尺寸较小的中高频喇叭，便 于将第二发声单元50放置在活动件40上并送至人耳耳孔处，使人耳处于有效听音区域。通过活动件40将第二发声单元50送至人耳耳孔处，使第二发声单元50距离人耳较近，保证第二发声单元50较低的响度就能够满足佩戴者听感需求，提高智能眼镜100的远场私密性，提升用户体验。在活动件40处于第二位置时，活动件40可以收起，活动件40与镜腿20的内表面相贴合，使第二发声单元50远离镜腿20的第二端。此时智能眼镜100发送全频信号，并将全频信号送至镜腿20上的第一发声单元30，第一发声单元30接收全频电信号并发出声音，此时，第一发声单元30可以作为全频喇叭使用，通过第一发声单元30的第一出声孔23和第二出声孔24传播的声波在远场进行抵消，保证用户隐私。
在本申请的一些具体实施方式中，镜腿20的内表面设有转轴，活动件40的第一端设有安装孔42，活动件40的第一端通过转轴与镜腿20可枢转地连接。镜腿20的宽度大于活动件40的宽度，活动件40位于第二位置时，活动件40在镜腿20上的正投影不超出镜腿20。活动件40的第一端设有避让槽43，避让槽43从活动件40的一条边沿向另一条边沿所在方向凹陷。
换句话说，镜腿20的内表面可以设置有转轴，活动件40的第一端可以设置有安装孔42(如图7和图8所示)，活动件40的第一端可以通过安装孔42与转轴相配合，以将活动件40可枢转地设置在镜腿20上。通过活动件40相对镜腿20转动实现活动件40在第一位置和第二位置之间的切换。在活动件40处于第一位置时，活动件40相对镜腿20转动至活动件40的第二端靠近人耳耳孔的位置处，使第二发声单元50靠近人耳耳孔处，保证人耳处于有效听音区域。第一发声单元30可以接收第一频段信号，第二发声单元50可以接收第二频段信号，并且在第一发声单元30与第二发声单元50分别接到第一频段信号和第二频段信号后发出声音，保证智能眼镜100有效提升远场私密性，且不影响近耳听感，有效提升用户体验。
在活动件40处于第二位置时，活动件40收起，活动件40转动至与镜腿20的内表面相贴合的位置处，使第二发声单元50远离镜腿20的第 二端。智能眼镜100发送全频信号，并将全频信号送至镜腿20上的第一发声单元30，第一发声单元30接收全频电信号并发出声音，此时，第一发声单元30可以作为全频喇叭使用，通过第一发声单元30的第一出声孔23和第二出声孔24传播的声波在远场进行抵消，保证用户隐私。
在本申请的一个实施例中，镜腿20的宽度可以大于活动件40的宽度，在活动件40位于第二位置时，活动件40在镜腿20上的正投影不超出镜腿20，保证活动件40可以收纳在镜腿20的内侧，不影响智能眼镜100的正常佩戴，同时保证智能眼镜100佩戴的外形美观。可选地，活动件40的第一端可以设置有避让槽43，避让槽43可以从活动件40的一条边沿向另一条边沿所在方向凹陷，通过在活动件40上设置避让槽43，便于用户通过避让槽43转动活动件40，保证活动件40在第一位置和第二位置切换时更加方便。
在本申请的一些具体实施方式中，活动件40为伸缩件，活动件40的第一端与镜腿20连接，活动件40的第二端相对于活动件40的第一端可伸缩，第二发声单元50设于活动件40的第二端。
也就是说，活动件40可以采用伸缩件，活动件40的第一端可以与镜腿20连接，活动件40的第二端可以相对于活动件40的第一端可伸缩，第二发声单元50可以设置在活动件40的第二端。当活动件40处于第一位置时，通过拉伸活动件40，使活动件40的第二端伸长至靠近人耳耳孔的位置处，从而使第二发声单元50靠近人耳耳孔处，保证人耳处于有效听音区域。第一发声单元30可以接收第一频段信号，第二发声单元50可以接收第二频段信号，并且在第一发声单元30与第二发声单元50分别接到第一频段信号和第二频段信号后发出声音，保证智能眼镜100有效提升远场私密性，且不影响近耳听感，有效提升用户体验。
在活动件40处于第二位置时，用户可以驱动活动件40缩回至镜腿20上，保证活动件40与镜腿20的内表面相贴合的位置处，从而使第二发声单元50远离镜腿20的第二端。智能眼镜100发送全频信号，并将全频信号送至镜腿20上的第一发声单元30，第一发声单元30接收全频电信号并发出声音，此时，第一发声单元30可以作为全频喇叭使用，通过第一发 声单元30的第一出声孔23和第二出声孔24传播的声波在远场进行抵消，保证用户隐私。
根据本申请的一个实施例，镜腿20设有滑槽25，滑槽25相对于镜腿20的延伸方向倾斜设置，活动件40沿滑槽25的延伸方向可活动地设于滑槽25内。
换句话说，参见图6，镜腿20设置有滑槽25，滑槽25可以相对于镜腿20的延伸方向倾斜延伸，即滑槽25在镜腿20的宽度方向上朝向镜腿20的第二端倾斜延伸。活动件40可以设置在滑槽25上，并且活动件40可以相对滑槽25滑动，当活动件40处于第一位置时，可以将活动件40滑出滑槽25，并将活动件40的第二端滑出至靠近人耳耳孔的位置处，从而使第二发声单元50靠近人耳耳孔处，保证人耳处于有效听音区域。第一发声单元30可以接收第一频段信号，第二发声单元50可以接收第二频段信号，并且在第一发声单元30与第二发声单元50分别接到第一频段信号和第二频段信号后发出声音，保证智能眼镜100有效提升远场私密性，且不影响近耳听感，有效提升用户体验。
在活动件40处于第二位置时，用户可以将活动件40滑回至镜腿20的滑槽25内，保证活动件40与镜腿20相贴合。此时智能眼镜100发送全频信号，并将全频信号送至镜腿20上的第一发声单元30，第一发声单元30接收全频电信号并发出声音，此时，第一发声单元30可以作为全频喇叭使用，通过第一发声单元30的第一出声孔23和第二出声孔24传播的声波在远场进行抵消，保证用户隐私。
当然，本领域技术人员应该能够理解，活动件40的具体形状以及活动件40与镜腿20的具体活动形式可以根据实际需要进行具体限定，只要能够使活动件40在第一位置和第二位置之间可切换的活动形式都应落入本申请的保护范围。同时，本申请的智能眼镜100可以为AR、VR、以及各种普通智能型眼镜，本申请的智能眼镜100的其他具体结构以及工作原理对于本领域技术人员来说是可以理解并且能够实现的。
总而言之，根据本申请实施例的智能眼镜100，通过在镜腿20上设置活动件40，活动件40在第一位置和第二位置之间可切换，在活动件40 处于第一位置时，活动件40相对于镜腿20展开，第二发声单元50靠近镜腿20的第二端，第二发声单元50靠近人耳，使人耳处于有效听音区域，第一发声单元30与第二发声单元50分别接收中低频信号和中高频信号并发出声音，保证第二发声单元50较低的响度就能满足佩戴者听感需求，使智能眼镜100在有效频段内大大提升远场私密性，且不影响近耳听感，有效提升用户体验。在活动件40处于第二位置时，活动件40收起，第二发声单元50远离镜腿20的第二端，通过第一发声单元30接收全频电信号并发出声音，并通过第一发声单元30的第一出声孔23和第二出声孔24传播的声波在远场进行抵消，保证用户隐私。
