具体实施方式
下面结合附图和实施例，对本申请作进一步的详细描述。特别指出的是，以下实施例仅用于说明本申请，但不对本申请的范围进行限定。同样的，以下实施例仅为本申请的部分实施例而非全部实施例，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。
本申请中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。本领域技术人员显式地和隐式地理解的是，本申请所描述的实施例可以与其他实施例相结合。
本申请中，电子设备10可以为耳机、智能眼镜等具有发声功能的终端设备。电子设备10可以包括机芯模组11和支撑组件12，支撑组件12可以与机芯模组11连接，以支撑机芯模组11佩戴至佩戴位。其中，机芯模组11可以在激励信号的作用下产生机械振动，前述机械振动可以基于骨传导方式和气传导方式中的至少一者传递至用户。进一步地，结合图1，支撑组件12可以设置成在佩戴状态下支撑在用户的耳部上，以及进一步绕设在用户的脑后。其中，机芯模组11的数量可以为两个，两个机芯模组11分别与支撑组件12的两端一一连接。当然，在其他一些实施方式中，支撑组件12也可以设置成在佩戴状态下支撑在用户的耳部以及鼻梁等生理部位上，还可以设置成在佩戴状态下绕过用户的头顶，在此不一一列举。基于此，前述佩戴位可以为用户的脸颊靠近耳部的位置、耳部背离头部一侧的某一位置或者其他生理部位，在此不一一列举。
作为示例性地，结合图2及图3，机芯模组11可以包括壳体组件111、换能装置112和振动面板113。其中，换能装置112设置成在激励信号的作用下产生机械振动，并设置在壳体组件111内；振动面板113与换能装置112连接，并用于与用户的皮肤间接抵靠或者直接接触，以传递前述机械振动。
进一步地，机芯模组11可以包括至少与振动面板113连接的贴脸组件114，例如贴脸组件114覆盖在振动面板113上，以使得振动面板113通过贴脸组件114与用户的皮肤接触，以兼顾电子设备10的音质和佩戴舒适度。
作为示例性地，结合图2及图3，机芯模组11可以包括第一传振片115，换能装置112可以通过第一传振片115与壳体组件111连接。如此，相较于换能装置112直接固定在壳体组件111内，这样有利于避免换能装置112产生的机械振动过多地传递至壳体组件111，从而有利于降低机芯模组11的漏音。其中，换能装置112可以包括支架1121、第二传振片1122、磁路系统和线圈1123，支架1121可以通过第一传振片115与壳体组件111连接，前述磁路系统可以通过第二传振片1122与支架1121连接，线圈1123与支架1121连接，并伸入前述磁路系统的磁间隙内。如此，在激励信号的作用下，通电后的线圈1123在前述磁路系统的磁场中产生使得支架1121相对于前述磁路系统发生相对运动的安培力，也即 产生机械振动。进一步地，前述磁路系统可以包括导磁罩1124和磁铁1125，磁铁1125可以固定于导磁罩1124的底部，并与导磁罩1124的侧壁之间形成前述磁间隙。其中，磁铁1125的数量可以为一个或者多个，例如图2及图3中所示的两个，相邻两个磁铁1125同极相对设置且两者之间可以夹持一导磁板，以使得磁铁1125的磁感线更多地穿过线圈1123。一些实施方式中，磁路系统可以包括有紧固件1126，紧固件1126可以将堆叠设置的多个磁铁1125及夹持于磁铁1125之间的导磁板固定，例如将第二传振片1122、磁铁1125与导磁罩1124的底部连接在一起。当然，在其他一些实施方式中，磁铁1125可以与导磁罩1124的底部通过胶水固定在一起。
作为示例性地，结合图2及图3，贴脸组件114可以包括贴脸套1141，贴脸套1141可以覆盖在振动面板113上，例如贴脸套1141通过粘结介质1142与振动面板113连接，有利于增加贴脸套1141在振动面板113上的平整度，以及增加贴脸套1141与振动面板113在振动过程中的同步性。其中，粘结介质1142可以设置成在不破坏贴脸组件114和振动面板113的情况下允许贴脸组件114整体从振动面板113上移除。如此，贴脸组件114不仅因可拆卸而便于用户在需求时更换新的，还因可整体上移除而避免破裂，有利于降低贴脸组件114从机芯模组11上拆卸的难度，从而提高贴脸组件114更换的便携性。
作为示例性地，粘结介质1142可以设置成使得贴脸套1141与振动面板113之间的剥离力介于4N与12N之间。其中，如果前述剥离力太小，也即粘结力太小，容易导致贴脸套1141在振动面板113上的平整度不足及其与振动面板113在振动过程中的同步性较差；如果前述剥离力太大，也即粘结力太大，容易导致贴脸组件114难以整体从振动面板113上移除。
作为示例性地，粘结介质1142与贴脸套1141之间的剥离力可以大于粘结介质1142与振动面板113之间的剥离力。如此，以在贴脸套1141从振动面板113上移除的过程中，粘结介质1142更倾向于随贴脸组件114一起被剥离而不是残留在振动面板113上，也即降低振动面板113上存在残胶的风险，以便于更换新的贴脸组件114。其中，粘结介质1142的材质更倾向于与贴脸套1141的相似，以便于增加粘结介质1142与贴脸套1141之间的粘结力。
作为示例性地，粘结介质1142可以为双面胶或者固化后的胶水。其中，前述双面胶的正反两面的胶层可以根据贴脸套1141和振动面板113的材质进行差异化设计，前述胶水的材质也可以选择与贴脸套1141的材质相似的胶材。进一步地，贴脸套1141的硬度可以小于振动面板113的硬度，粘结介质1142的硬度也可以小于振动面板113的硬度。其中，振动面板113的材质可以为聚碳酸酯或其中混有玻璃纤维、碳纤维中的至少一种，贴脸套1141的材质可以为硅胶、橡胶等。因此，前述胶水可以为硅胶类软胶水。
作为示例性地，粘结介质1142的面积与振动面板113的面积之间的比值可以介于0.8与1之间，例如粘结介质1142涂满整个振动面板113(俗称“全贴合”)，再例如粘结介质1142呈网格状。其中，如果前述比值太小，容易导致贴脸套1141在振动面板113上的平整度不足及其与振动面板113在振动过程中的同步性较差。值得注意的是：贴脸套1141的面积一般会大于振动面板113的面积，如果粘结介质1142的面积大于振动面板113的面积，那么粘结介质1142不与振动面板113接触的那部分的面积不算作粘结介质1142的面积。进一步地，粘结介质1142的厚度与贴脸套1141的厚度之间的比值可以介于0.4与1.2之间。其中，如果前述比值太小，容易导致粘结介质1142所提供的粘结力不足；如果前述比值太大，容易导致换能装置112产生的机械振动在经由贴脸套1141和粘结介质1142传递的过程中损耗过大。进一步地，粘结介质1142的厚度可以小于贴脸套1141的厚度。值得注意的是：在贴脸套1141通过粘结介质1142与振动面板113连接的一部分的厚度不等于贴脸套1141不与振动面板113连接的另一部分的厚度的实施方式中，在计算粘结介质1142的厚度与贴脸套1141的厚度之间的比值或大小关系时，贴脸套1141的厚度可以具体指贴脸套1141通过粘结介质1142与振动面板113连接的那部分(例如后文中提及的主体部11411)的厚度。
需要说明的是：电子设备10可以包括几副贴脸组件114，以便于用户在需要时更换新的。其中，粘结介质1142既可以预先固定在贴脸套1141上，也即粘结介质1142与贴脸套1141作为一个整体。其中，粘结介质1142与振动面板113粘结的一侧可以设置有离型纸，以便于维持粘结介质1142的粘性，用户在更换新的贴脸组件114时撕掉其上的离型纸即可。当然，在其他一些实施方式中，粘结介质1142也可以独立于贴脸套1141。
作为示例性地，结合图2至图4，贴脸组件114可以包括与贴脸套1141连接的补强件1143，补强件1143的硬度大于贴脸套1141的硬度，以增加贴脸组件114局部的结构强度。例如：贴脸套1141的材质为硅胶、橡胶等，补强件1143的材质为聚碳酸酯或其中混有玻璃纤维、碳纤维中的至少一种，两者通过注塑工艺构成一体成型的结构部件。其中，贴脸组件114可以通过补强件1143与壳体组件111可拆卸连接，以避免贴脸组件114的边缘区域在贴脸组件114跟随振动面板113振动的过程中碰撞壳体 组件111。换言之，贴脸组件114的中间区域和边缘区域可以分别与振动面板113和壳体组件111可拆卸连接。相应地，贴脸组件114与壳体组件111围设形成一个至少容纳换能装置112和振动面板113的腔体。当然，在其他一些诸如贴脸套1141的边缘区域与壳体组件111具有足够大的安全间隙的实施方式中，贴脸组件114也可以不包括补强件1143，贴脸套1141的边缘区域也因此可以不与壳体组件111连接。进一步地，在其他一些诸如贴脸组件114不需要更换的实施方式中，贴脸组件114也可以设置成不可拆卸。
在一些实施方式中，壳体组件111可以包括机芯壳体1111，机芯壳体1111的一端呈敞口状，换能装置112可以至少部分位于机芯壳体1111内，振动面板113则可以至少部分位于机芯壳体1111外。其中，补强件1143可以至少部分位于机芯壳体1111的敞口端内，并可以与机芯壳体1111可拆卸连接，以使得贴脸组件114与壳体组件111之间具有一定的结合力。
在一些实施方式中，壳体组件111可以包括机芯壳体1111和盖设在机芯壳体1111的敞口端的机芯盖板1112，换能装置112可以至少部分位于机芯壳体1111内，振动面板113则可以至少部分位于机芯壳体1111外，也即贴脸组件114和换能装置112可以分别位于机芯盖板1112的相背两侧。相应地，机芯盖板1112设置有允许振动面板113与换能装置112连接的第一避让孔11121。其中，补强件1143可以至少部分位于机芯壳体1111外，并可以与机芯盖板1112可拆卸连接，以使得贴脸组件114与壳体组件111之间具有一定的结合力。
进一步地，换能装置112与机芯壳体1111的底部可以在换能装置112的振动方向(例如图3中箭头D1所示的方向)上间隔设置，以降低换能装置112振动时与机芯壳体1111的底部发生碰撞的风险。一些实施方式中，换能装置112与机芯壳体1111的底部可以在换能装置112的振动方向上间隔距离在一定阈值范围，能够保证机芯壳体1111的厚度满足需求的同时，在机芯模组11发生跌落、碰撞等极限工况下。
作为示例性地，结合图5至图8，机芯壳体1111的敞口端和凸缘部11432中的一者可以设置有卡扣凸起11111，另一者可以设置有用于容纳卡扣凸起11111的卡扣凹槽11434，卡扣凸起11111嵌入卡扣凹槽11434内，也即两者配合使得补强件1143和机芯壳体1111可拆卸连接，简单、可靠。其中，卡扣凸起11111的数量可以为多个，例如图8中所示的四个；卡扣凹槽11434的数量可以与卡扣凸起11111的数量相等，例如图6中所示的四个，并一一对应。
作为示例性地，结合图5及图6，补强件1143可以包括环状主体部11431和与环状主体部11431连接的凸缘部11432，贴脸套1141可以至少与环状主体部11431连接，例如注塑连接在一起。其中，凸缘部11432的数量可以为多个，例如图6中所示的四个，多个凸缘部11432在环状主体部11431的周向上间隔设置。相应地，凸缘部11432与机芯壳体1111可拆卸连接，以实现补强件1143与机芯壳体1111可拆卸连接。进一步地，补强件1143可以包括与环状主体部11431连接的凸起部11433，贴脸套1141可以进一步与凸起部11433连接，有利于增加贴脸套1141与补强件1143之间的连接面积，从而增加两者的结合强度。其中，凸起部11433的数量可以为多个，例如图6中所示的八个，多个凸起部11433在环状主体部11431的周向上间隔设置，例如多个凸缘部11432和多个凸起部11433在环状主体部11431的周向上交替间隔设置。
进一步地，补强件1143被贴脸套1141包覆的包覆面积与补强件1143的表面积之间的比值可以大于或者等于0.8，例如环状主体部11431和凸起部11433全部被贴脸套1141包覆，以尽可能增加贴脸套1141与补强件1143之间的连接面积。
作为示例性地，结合图2及图3、图5及图6，贴脸套1141可以包括一体连接的主体部11411、过渡部11412和包覆部11413，主体部11411和包覆部11413可以在振动方向D1上彼此错开，包覆部11413在一垂直于振动方向D1的参考平面上的正投影环绕主体部11411在前述参考平面上的正投影，也即包覆部11413位于主体部11411的外围，过渡部11412连接主体部11411和包覆部11413。其中，主体部11411可以通过粘结介质1142与振动面板113连接，包覆部11413可以包覆补强件1143，例如至少包覆环状主体部11431。进一步地，包覆部11413可以在振动方向D1上相较于主体部11411更靠近换能装置112，以便于振动面板113通过主体部11411与用户的皮肤接触。除此之外，在贴脸套1141设置有连通孔11414的实施方式中，例如连通孔11414设置在过渡部11412上，还有利于避免连通孔11414被用户的皮肤覆盖。
进一步地，在平行于振动方向D1的参考截面(例如纸面)上，过渡部11412可以呈弯曲状设置，以增加过渡部11412的变形能力，有利于避免振动面板113的振动被壳体组件111限制，尤其是在贴脸组件114的中间区域和边缘区域分别与振动面板113和壳体组件111连接的实施方式中。其中，在从主体部11411到包覆部11413的延伸方向上，过渡部11412可以先逐渐靠近换能装置112后逐渐远离换能装置112，或者过渡部11412可以先逐渐靠近换能装置112后平行于第一传振片115所在平面。
作为示例性地，过渡部11412在振动方向D1上的活动余量可以大于或者等于换能装置112的最大振幅。其中，前述活动余量可以指过渡部11412由弯曲状变形成平直状时的位移量。
作为示例性地，结合图2及图3、图5至图8，机芯壳体1111的敞口端可以设置有连通孔11112，连通孔11112在环状主体部11431的周向上位于相邻两个凸缘部11432之间，连通孔11112经对应的两个凸缘部11432之间的通道连通机芯模组11的内外。其中，由于凸缘部11432的数量可以为多个，例如图6中所示的四个，使得连通孔11112的数量也可以为多个，例如图7及图8中所示的四个，也即连通孔11112可以与前述通道一一对应。如此，虽然机芯壳体1111在换能装置112的带动作用下一般会在远场形成第一漏音，但是贴脸组件114与壳体组件111围设形成的腔体中的空气在换能装置112的作用下并经由连通孔11112及前述通道在远场形成第二漏音，且前述第二漏音的相位和前述第一漏音的相位(接近)互为反相，例如前述第二漏音的相位的绝对值和前述第一漏音的相位的绝对值之差小于60°，使得两者能够在远场反相相消，有利于降低机芯模组11在远场的漏音。值得注意的是：连通孔11112可以是在设置机芯壳体1111的敞口端上完整的通孔，也可以是在机芯壳体1111的敞口端上的缺口。
进一步地，贴脸套1141可以设置有连通孔11414，例如连通孔11414设置在过渡部11412上。其中，连通孔11414的作用与连通孔11112的作用相同或者相似，在此不再赘述。值得注意的是：在仅设置连通孔11112即可降低机芯模组11在远场的漏音的实施方式中，贴脸套1141也可以不设置连通孔11414，这样有利于避免汗液等侵入电子设备10内。类似地，在仅设置连通孔11414即可降低机芯模组11在远场的漏音的实施方式中，机芯壳体1111的敞口端也可以不设置连通孔11112，以简化机芯壳体1111的结构。
本申请的发明人在长期的研发过程中发现：虽然上述第二漏音有利于降低机芯模组11在远场的漏音，但是上述第二漏音的频响曲线较为紊乱，使之具有一定的优化空间。为此，结合图2及图3，壳体组件111可以包括盖设在机芯壳体1111的敞口端的机芯盖板1112，贴脸组件114和换能装置112可以分别位于机芯盖板1112的相背两侧，机芯盖板1112设置有允许振动面板113与换能装置112连接的第一避让孔11121。其中，机芯盖板1112可以将贴脸组件114与壳体组件111围设形成的腔体一分为二，也即机芯盖板1112和机芯壳体1111配合形成第一腔体，贴脸组件114和壳体组件111配合形成第二腔体，例如前述第一腔体和前述第二腔体分别位于机芯盖板1112相背的两侧。进一步地，换能装置112可以至少部分位于前述第一腔体内，振动面板113可以至少部分位于前述第二腔体内。相应地，机芯模组11设置有连通前述第二腔体与机芯模组11外部的通道，以允许前述第一腔体中的空气在换能装置112的作用下并经由前述通道在远场形成第三漏音，且前述第三漏音的相位和上述第一漏音的相位(接近)互为反相，例如前述第三漏音的相位的绝对值和上述第一漏音的相位的绝对值之差小于60°，使得两者能够在远场反相相消，有利于降低机芯模组11在远场的漏音。如此，在机芯盖板1112的限制作用下，前述第一腔体内的空气可以在一定程度上被限制出入机芯模组11，有利于避免与上述第一漏音在远场反相相消的漏音的频响曲线过于紊乱，从而增加机芯模组11的降漏音效果。基于亥姆霍兹共振腔，前述通道的面积可以尽可能得大，例如增加前述通道的数量，再例如增加每一前述通道的孔径，以使得前述第三漏音的谐振频率尽可能往频率较高的频段(例如大于4kHz的频率范围)偏移，有利于进一步避免前述第三漏音被用户听到。
作为示例性地，上述通道的数量可以为多个，这样有利于增大上述通道的面积。其中，多个上述通道可以全部设置在贴脸套1141、补强件1143、机芯壳体1111等结构部件的任意一者上；多个上述通道也可以一部分设置在贴脸套1141、补强件1143、机芯壳体1111等结构部件的一者上，另一部分设置在贴脸套1141、补强件1143、机芯壳体1111等结构部件的另一者上。
进一步地，对于任意一个上述通道而言，上述通道至少可以通过如下实施方式中的任意一者形成。
在一些实施方式中，例如补强件1143至少部分位于机芯壳体1111的敞口端内，上述通道可以至少部分设置在补强件1143上。例如：凸缘部11432及相邻两个凸缘部11432之间的间隔区域均位于机芯壳体1111的敞口端内，相邻两个凸缘部11432之间的间隔区域构成上述通道的一部分，连通孔11112构成同一通道的另一部分。再例如：凸缘部11432及相邻两个凸缘部11432之间的间隔区域均位于机芯壳体1111的敞口端内，贴脸组件114与机芯壳体1111之间存在装配间隙，相邻两个凸缘部11432之间的间隔区域构成上述通道的一部分，贴脸组件114与机芯壳体1111之间的装配间隙构成同一通道的另一部分。
在一些实施方式中，例如补强件1143至少部分位于机芯壳体1111的敞口端内，上述通道可以至少部分设置在机芯壳体1111的敞口端。例如：机芯壳体1111的敞口端设有连通孔11112，贴脸组件114与机芯盖板1112接触的一侧设置成不平整的表面，例如高低起伏的波浪形表面，使得至少部分补强件1143与机芯盖板1112不接触以形成预留间隙。并且，贴脸组件114与机芯壳体1111之间存在装配间隙，贴脸组件114与机芯盖板1112之间的预留间隙以及贴脸组件114与机芯壳体1111之间的装配间隙构成 上述通道的一部分，连通孔11112构成同一通道的另一部分。再例如：机芯壳体1111的敞口端设有连通孔11112，贴脸组件114与机芯壳体1111和机芯盖板1112之间均存在装配间隙，连通孔11112构成上述通道的一部分，贴脸组件114与机芯壳体1111和机芯盖板1112之间的装配间隙构成同一通道的另一部分。
在一些实施方式中，上述通道可以设置在贴脸套1141上，例如连通孔11414作为上述通道。
在一些实施方式中，例如补强件1143至少部分位于机芯壳体1111的敞口端外，上述通道可以仅设置在补强件1143上，例如相邻两个凸缘部11432之间的间隔区域至少部分位于机芯壳体1111的敞口端外，相邻两个凸缘部11432之间的间隔区域即可作为上述通道。
在一些实施方式中，例如补强件1143至少部分位于机芯壳体1111的敞口端内，上述通道可以至少部分设置在机芯壳体1111的敞口端，例如连通孔11112作为上述通道，至少部分补强件1143与机芯盖板1112不接触，以使得上述第一腔体可以经由补强件1143与机芯盖板1112之间的间隙与连通孔11112连通。
作为示例性地，结合图3，上述通道可以设置成使得上述第二腔体与机芯模组11外部之间的气体流动方向(例如图3中箭头D2所示的方向)与振动方向D1相交，例如上述通道的延伸方向不朝向机芯模组11在佩戴状态下朝向用户的皮肤的一侧。如此，有利于避免上述通道被用户的皮肤覆盖，从而使得上述第三漏音与上述第一漏音更好地在远场反相相消。
作为示例性地，结合图2及图3，机芯盖板1112可以包括一体连接的内顶部11122、连接部11123和外底部11124，内顶部11122和外底部11124在振动方向D1上彼此错开，外底部11124在一垂直于振动方向D1的参考平面上的正投影环绕内顶部11122在前述参考平面上的正投影，也即外底部11124位于内顶部11122的外围，连接部11123连接内顶部11122和外底部11124。其中，外底部11124可以与壳体组件111连接，外底部11124在振动方向D1上相较于内顶部11122更靠近换能装置112，有利于避开机芯壳体1111上的连通孔11112。相应地，结合图4，第一避让孔11121可以设置在内顶部11122上。
作为示例性地，结合图2及图3，壳体组件111可以包括与机芯盖板1112连接的密封膜1113，密封膜1113设置有允许振动面板113与换能装置112连接的第二避让孔11131，第二避让孔11131的孔径小于第一避让孔11121的孔径，密封膜1113用于密封第一避让孔11121的装配间隙。其中，前述装配间隙是指振动面板113与换能装置112连接成的结构与第一避让孔11121的孔壁面之间的空隙，装配间隙能够避免振动面板113和/或换能装置112与机芯盖板1112发生碰撞。如此，在机芯盖板1112和密封膜1113的限制作用下，上述第一腔体内的空气可以最大程度地被限制出入机芯模组11，有利于进一步避免与上述第一漏音在远场反相相消的漏音的频响曲线过于紊乱，从而增加机芯模组11的降漏音效果。除此之外，由于设置有密封膜1113，使得第一避让孔11121的孔径能够大些，有利于进一步避免前述碰撞。相应地，振动面板113可以经第二避让孔11131及第一避让孔11112与支架1121连接。
作为示例性地，结合图2至图4，密封膜1113可以包括一体连接的第一连接部11132、折环部11133和第二连接部11134，折环部11133连接第一连接部11132和第二连接部11134。其中，第一连接部11132和第二连接部11134的刚度可以分别大于折环部11133的刚度，例如第一连接部11132和第二连接部11134分别呈环状设置而折环部11133在平行于振动方向D1的参考截面上的截面形状呈U字型设置，以使得第一连接部11132和第二连接部11134能够在振动方向D1上发生相对运动。相应地，第二避让孔11131可以设置在第二连接部11134上，也即第一连接部11132位于第二连接部11134的外围。此时，第一连接部11132可以与机芯盖板1112连接，第二连接部11134可以与振动面板113或者换能装置112连接，以密封第一避让孔11121的装配间隙。
本申请一些实施方式中，密封膜1113为完整的膜结构。需要说明的是，本申请的其它一些实施方式中，密封膜1113可以设置有至少一个微孔，例如微孔的面积小于或者等于2mm2，以在密封膜1113进一步优化降漏音的同时减小上述第一腔体内外的压力差，也即微孔可以起到泄压的作用。当然，密封膜1113也可以不设置微孔，机芯壳体1111、机芯盖板1112和密封膜1113等结构部件组装之后形成上述第一腔体时各个结构部件之间的装配间隙可以起到泄压的作用。
进一步地，密封膜1113的材质可以为橡胶、硅胶等。
进一步地，折环部11133在振动方向D1上朝着背离换能装置112的方向凸起，也即折环部11133伸入上述第一腔体内。如此，相较于折环部11133伸入上述第二腔体内，经由上述通道侵入上述第一腔体内的液滴、灰尘等更不易堆积在折环部11133上，有利于维持密封膜1113的可靠性。
作为示例性地，结合图2及图3、图9及图10，支架1121可以包括第一支架11211、第二支架11212和悬架11213。其中，第一支架11211可以与第一传振片115的中心区域连接，例如两者通过金属嵌件注塑工艺形成一体成型的结构部件；第二支架11212可以与第二传振片1122的周边区域连接，悬架11213 可以与第二传振片1122的中心区域连接，例如三者通过金属嵌件注塑工艺形成一体成型的结构部件。进一步地，第一支架11211和第二支架11212中的一者上可以设置有接插柱11214，另一者上可以设置有用于容纳接插柱11214的接插孔11215，接插柱11214嵌入接插孔11215内，以使得第一支架11211和第二支架11212连接。其中，接插柱11214和接插孔11215的数量可以分别为多个，且两者一一对应，例如图9中所示的四个。相应地，上述磁路系统与悬架11213连接，例如紧固件1126将悬架11213、磁铁1125和导磁罩1124的底部连接在一起，或者通过粘胶将悬架11213、磁铁1125和导磁罩1124粘接在一起；线圈1123可以与第二支架11212连接，密封膜1113可以与第一支架11211和振动面板113中的至少一者连接。

作为示例性地，结合图2至图4，支架1121可以设置有第一支撑端面11218，例如第一支撑端面11218为接插部11217不与主体部11216连接的端面，振动面板113可以设置有第二支撑端面1131，第一支撑端面11218和第二支撑端面1131可以共同夹持第二连接部11134。换言之，振动面板113与支架1121彼此相向的支撑端面共同夹持第二连接部11134。如此，振动面板113与支架1121连接时还可以进一步将密封膜1113压持在支架1121上，简单、可靠，一举两得。
作为示例性地，结合图4，机芯盖板1112背离换能装置112的一侧可以设置有凹陷区11125，第一避让孔11121设置在凹陷区11125的底部，第一连接部11132可以与凹陷区11125的底部连接，并环绕第一避让孔11121。如此，凹陷区11125不仅可以在密封膜1113与机芯盖板1112组装的过程中起到定位的作用，还可以增加上述第一腔体的腔壁面的平整度。相应地，凹陷区11125可以设置在内顶部11122上。
进一步地，凹陷区11125可以包括第一凹陷段11126和第二凹陷段11127，第一凹陷段11126在振动方向D1上相较于第二凹陷段11127更靠近换能装置112，第二凹陷段11127在垂直于振动方向D1的方向上的尺寸大于第一凹陷段11126在垂直于振动方向D1的方向上的尺寸。简而言之，凹陷区11125在振动方向D1上划分成两段，第一避让孔11121设置在第一凹陷段11126的底部。其中，第一连接部11132固定在第一凹陷段11126的底部上。
在一些实施方式中，第一连接部11132可以通过双面胶与第一凹陷段11126的底部连接，且第二凹陷段11127容纳有胶水，有利于增加密封膜1113与机芯盖板1112连接的可靠性。换言之，第二凹陷段11127的侧壁与第一连接部11132配合形成一环状的容胶槽，有利于避免溢胶。
在一些实施方式中，第一连接部11132可以通过胶水与第一凹陷段11126的底部连接。或者，一些实施方式中，第一连接部11132可以通过胶水与第二凹陷段11127连接。
基于上述的相关描述，第一连接部11132可以通过第一胶体11135固定在第一凹陷段11126的底部上，以使得密封膜1113与机芯盖板1112连接；第二连接部11134可以通过第二胶体11136固定在接插部11217不与主体部11216连接的端面(也即第一支撑端面11218)上，以使得密封膜1113与支架1121连接。其中，振动面板113还可以进一步将密封膜1113压持在支架1121上。进一步地，第一胶体11135和第二胶体11136可以分别为双面胶或者胶水。值得注意的是：当第一胶体11135和第二胶体11136分别为双面胶时，他们可以分别预固定在密封膜1113上；而当第一胶体11135和第二胶体11136分别为胶水时，他们可以分别预固定在机芯盖板1112和支架1121上。进一步地，在不考虑加工误差、组装误差等因素的情况下，第一支撑端面11218与第一凹陷段11126的底部在振动方向D1上可以平齐。

进一步地，第一环状承台11114上可以设置有多个立柱11115，例如图8中所示的六个，机芯盖板1112可以支撑在第一环状承台11114上，并可以与立柱11115接插配合，立柱11115至少在机芯盖板1112与机芯壳体1111组装的过程中起到定位的作用。相应地，外底部11124可以支撑在第一环状承台11114上，并可以与立柱11115接插配合。其中，多个立柱11115、多个卡扣部(例如卡扣凸起11111，下文中不再赘述)和多个连通孔11112可以分别在第一筒状侧壁11113的周向上间隔设置，多个卡扣部和多个连通孔11112在第一筒状侧壁11113的周向上彼此错开，以使得三者合理分布。进一步地，多个立柱11115中的至少两个和多个连通孔11112中的至少两个可以在第一筒状侧壁11113的周向上一一对应地至少部分重叠，以使得立柱11115位于相邻两个卡扣部之间。
作为示例性地，立柱11115可以为热熔柱，以进一步将机芯盖板1112固定在第一环状承台11114上。其中，图2及图3、图7及图8中所示的立柱11115为其热熔之前的形态，其热熔之后一般不超过对应的连通孔11112，以避免对上述第一腔体内空气的出入造成干扰。
作为示例性地，结合图7及图8，壳体组件111具有垂直于振动方向D1且彼此正交的长轴(例如图8中箭头D3所示的方向)和短轴(例如图8中箭头D4所示的方向)，第一环状承台11114在长轴D3上的尺寸可以大于第一环状承台11114在短轴D4上的尺寸，例如第一环状承台11114呈跑道型设置。其中，多个立柱11115可以在长轴D3和短轴D4的两侧均对称设置，以增加机芯盖板1112与机芯壳体1111连接的可靠性；类似地，多个卡扣部可以在长轴D3和短轴D4的两侧均对称设置，以增加贴脸组件114与机芯壳体1111的可靠性。
作为示例性地，结合图7及图8，多个立柱11115与多个卡扣部可以错位设置，有利于避免诸如注塑成型的成型工艺中出现脱模干涉。相应地，在第一筒状侧壁11113的周向上，任意相邻两个卡扣部之间可以间隔设置有一个连通孔11112，以使得连通孔11112在第一筒状侧壁11113的周向上的尺寸尽可能得大。
作为示例性地，结合图7及图8，沿振动方向D1观察，连通孔11112可以分成四组，两组连通孔11112可以在长轴D3上相对设置，余下的两组连通孔11112则可以在短轴D4上相对设置。如此，有利于降低上述第一腔体内的驻波。其中，虽然图7及图8中每一组连通孔11112仅具有一个连通孔11112，但是本领域的技术人员可以根据实际的需要在至少一组连通孔11112中设置多个连通孔11112，在此不再赘述。
作为示例性地，结合图2、图3及图11，机芯模组11可以包括麦克风组件116，麦克风组件116设置在壳体组件111内。其中，麦克风组件116可以拾取环境声、用户语音等声音中的至少一者。进一步地，麦克风组件116可以包括第一麦克风1161，第一麦克风1161沿振动方向D1正投影至换能装置112时落在换能装置112上，例如第一麦克风1161固定在壳体组件111的底部上且在振动方向D1上与换能装置112间隔设置。其中，机芯模组11可以进一步包括设置在壳体组件111内的限位件117，限位件117用于在换能装置112沿振动方向D1的运动幅度超过预设的幅度阈值时止挡换能装置112，以使得换能装置112与第一麦克风1161之间保持预定距离，这样有利于避免第一麦克风1161被换能装置112撞坏，尤其是在机芯模组11发生跌落、碰撞等极限工况下。
进一步地，上述幅度阈值可以大于机芯模组11正常工作时换能装置112的最大振幅。换言之，用户日常使用电子设备10时，即便把电子设备10的音量调到最大，换能装置112也不会与限位件117等结构发生碰撞，以避免机芯模组11出现杂音。
在一些实施方式中，限位件117可以呈环状或者块状设置。其中，限位件117的中心与换能装置112的中心可以在振动方向D1上对齐，以使得限位件117止挡换能装置112时作用力的分布更加均匀。本申请一些实施方式中，限位件117可以与第一麦克风1161相邻设置，以通过限位件117更好的避免第一麦克风1161被换能装置112撞坏，尤其是在机芯模组11发生跌落、碰撞等极限工况下。其中，限位件117与第一麦克风1161相邻设置是指在限位件117的中心与第一麦克风1161中心的连线方向上，限位件117可以与第一麦克风1161之间的距离至少小于换能装置112在该连线方向上尺寸的一半。例如，限位件117与第一麦克风1161相邻设置是指在限位件117的中心与第一麦克风1161中心的连线方向上，限位件117可以与第一麦克风1161之间的距离至少小于换能装置112在该连线方向上尺寸的1/2、1/3、1/4、1/5等。在一些实施方式中，限位件117的材质可以为聚碳酸酯或其中混有玻璃纤维、碳纤维中的至少一种。或者，限位件117的材质也可以为硅胶、橡胶、海绵等具有一定弹性的结构，当换能装置112与限位件117碰撞时，限位件117能够提供一定的缓冲，避免或减轻换能装置112可能造成的 损坏。可以理解的是，本申请中，限位件117还可以为其它的任意种类材料，本申请不对其进行具体限制。其中，限位件117可以固定在壳体组件111的底部上，也可以固定在换能装置112上。进一步地，当限位件117固定在壳体组件111的底部上时，限位件117和壳体组件111可以为一体成型的结构部件。
作为示例性地，结合图2，限位件117与第一麦克风1161可以设置成保持相对固定，例如两者分别固定在机芯壳体1111的底部上，再例如限位件117作为机芯壳体1111的一部分结构而第一麦克风1161固定在机芯壳体1111的底部上。其中，换能装置112沿振动方向D1的正投影覆盖第一麦克风1161和限位件117上，以便于限位件117止挡换能装置112。进一步地，在振动方向D1上，限位件117朝向换能装置112的一侧高于第一麦克风1161朝向换能装置112的一侧，以避免第一麦克风1161被换能装置112撞坏。
一些其它实施例中，限位件117与第一麦克风1161可以均固定在壳体组件111的底部上，限位件117固定在换能装置112上，第一麦克风1161固定在壳体组件111的底部上。在振动方向D1上，限位件117朝向壳体组件111的底部的一侧与壳体组件111的底部之间的距离小于第一麦克风1161朝向换能装置112的一侧与换能装置112的距离，以避免第一麦克风1161被换能装置112撞坏。
作为示例性地，结合图2及图3，麦克风组件116可以包括第二麦克风1162，以及连接第一麦克风1161和第二麦克风1162的柔性电路板1163，第二麦克风1162固定在机芯壳体1111的侧壁上。其中，机芯壳体1111可以设置有走线槽，柔性电路板1163固定在前述走线槽内。如此，前述走线槽可以在柔性电路板1163与机芯壳体1111组装的过程中起到定位的作用；而且当两者通过胶水连接时，前述走线槽还可以起到防止溢胶的作用。此时，由于柔性电路板1163固定在前述走线槽内，使得柔性电路板1163所在的区域即可简单地视作前述走线槽。进一步地，限位件117和前述走线槽彼此错开，以避免两者在加工过程中发生干涉。相应地，机芯壳体1111上可以设置有分别与第一麦克风1161和第二麦克风1162配合的拾音孔。

作为示例性地，结合图2及图3，机芯壳体1111可以包括第二筒状侧壁11116和与第二筒状侧壁11116的一端连接的底壁11117，第二筒状侧壁11116的敞口端可以设置有第二环状承台11118，第二筒状侧壁11116部分伸入第一筒状侧壁11113内，以使得第一筒状侧壁11113支撑在第二环状承台11118上。其中，第一筒状侧壁11113和第二筒状侧壁11116彼此重叠的部分可以设置有卡扣结构，以使得两者卡接固定；第二环状承台11118上可以设有容胶槽，以使得第一筒状侧壁11113与第二环状承台11118胶接固定，这样有利于增加第一筒状侧壁11113和第二筒状侧壁11116连接的可靠性。相应地，第一麦克风1161可以固定在底壁11117上，第二麦克风1162可以固定在第二筒状侧壁11116上，上述走线槽则可以一部分开设在底壁11117另一部分开设在第二筒状侧壁11116上；限位件117可以固定在底壁11117上或者作为底壁11117的一部分结构。
基于上述的相关描述，机芯壳体1111可以包括第一壳体和与第一壳体连接的第二壳体。其中，第一壳体可以包括第一筒状侧壁11113和与第一筒状侧壁11113的内壁面连接的第一环状承台11114，第二壳体可以包括第二筒状侧壁11116和与第二筒状侧壁11116的一端连接的底壁11117，第二筒状侧壁11116与第一筒状侧壁11113连接，以使得第二壳体密封第一筒状侧壁11113的一端，第一筒状侧壁11113的另一端则呈敞口状。相应地，麦克风组件116可以固定在第二壳体内，且第二壳体的深度相对较浅，这样有利于降低麦克风组件116的组装难度。进一步地，壳体组件111可以包括包覆在第二壳体外侧的柔性覆层1114，例如柔性覆层1114包覆在第二筒状侧壁11116和底壁11117的外侧，柔性覆层1114的外表面与第一筒状侧壁11113的外表面可以平齐，以填补第一筒状侧壁11113与第二筒状侧壁11116之间的段差。其中，柔性覆层1114的硬度可以小于机芯壳体1111的硬度。
作为示例性地，结合图12、图15及图21，电子设备10可以包括壳体组件121，以及设置在壳体组件121内的电路板1221和天线支架123，天线支架123可以支撑在电路板1221的一侧。其中，壳体组件121可以包括仓体1211和设置在仓体1211的侧壁内的灯罩1222，天线支架123和电路板1221至少部分收容于仓体1211内，天线支架123可以位于电路板1221朝向灯罩1222的一侧。进一步地，电路板1221朝向灯罩1222的一侧可以设置有指示灯1223，天线支架123可以包括天线支撑部1231和与 天线支撑部1231连接的导光部1232，导光部1232及灯罩1222均为透光件，导光部1232设置成引导指示灯1223发出的光线出射至电子设备10的外部，例如指示灯1223发出的光线经导光部1232传播至灯罩1222进而出射至电子设备10的外部。如此，即便指示灯1223与灯罩1222之间因存在天线支架123而间距较大，但是在导光部1232的引导下，有利于降低指示灯1223发出的光线的损耗，使得指示灯1223无需提高发光功率，从而降低指示灯1223的功耗，以及延长指示灯1223的使用寿命。
一些实施方式中，导光部1232的外表面可以涂覆反光涂层或者形成咬花面，上述光线在导光部1232内部折射，减少从导光部1232的侧面出射的漏光，提高上述光线利用率。其中，导光部1232朝向指示灯1223的入光面和朝向灯罩1222的出光面需要裸露出来，例如不涂覆反光涂层或者不形成咬花面，以允许上述穿过导光部1232。
作为示例性地，结合图12、图15及图21，灯罩1222在电路板1221上的正投影的中心可以与指示灯1223的中心不重合，也即灯罩1222相对于指示灯1223偏置，以使得灯罩1222的设置更加灵活。其中，在电路板1221的法线方向(例如图12及图15中箭头D5所示的方向)上，导光部1232靠近电路板1221的一端的横截面积可以大于导光部1232靠近灯罩1222的另一端的横截面积，以改变指示灯1223发出的光线的光路，以及使得指示灯1223发出的到达灯罩1222的光线更加聚集。当然，灯罩1222在电路板1221上的正投影的中心也可以与指示灯1223的中心重合。
作为示例性地，结合图12，导光部1232朝向指示灯1223的端面可以设置成向导光部1232的内部凹陷的弧面，类似于凹面结构，以更好地汇集指示灯1223发出的光线。
作为示例性地，结合图12及图21，天线支架123可以包括连接导光部1232与天线支撑部1231的连接筋1233，也即导光部1232通过连接筋1233与天线支撑部1231连接。进一步地，连接筋1233在法线方向D5上的厚度与导光部1232在法线方向D5上的高度之间的比值可以介于0.3与0.5之间。其中，如果前述比值太小，容易导致导光部1232与天线支撑部1231之间的连接强度不足；如果前述比值太大，容易导致指示灯1223发出的光线过多地经由连接筋1233漏光至天线支撑部1231。
在一些实施方式中，天线支撑部1231、导光部1232和连接筋1233可以为相同材料的一体成型结构件，例如通过注塑工艺一体成型。
在一些实施方式中，天线支撑部1231和导光部1232可以为不同材料的一体成型结构件，例如通过双色注塑工艺一体成型。其中，连接筋1233可以作为天线支撑部1231或者导光部1232的一部分结构。
作为示例性地，结合图12、图17及图21，天线支撑部1231背离电路板1221的一侧可以设置有天线图案1224，天线图案1224可以通过金属弹性件1225抵接在电路板1221上，以实现电接触。其中，天线图案1224可以位于天线支撑部1231朝向灯罩1222的一侧，以增大天线图案1224与电路板1221之间的间距，也即增大天线净空区，从而增加天线图案1224的抗干扰性。进一步地，天线图案1224可以借助激光直接成型技术(Laser-Direct-structuring,LDS)成型在天线支撑部1231上，也可以为粘贴在天线支撑部1231上的柔性电路板。其中，金属弹性件1225可以为pogo-PIN或者金属弹片等，在此不作限制。进一步地，金属弹性件1225可以固定在电路板1221上。
需要说明的是：结合图1及图12，在佩戴状态下，灯罩1222可以相较于电路板1221更靠近外侧，以使得指示灯1223发出的并经由导光部1232及灯罩1222引导的光线不会被遮挡。类似地，在佩戴状态下，天线图案1224可以相较于电路板1221更靠近外侧，例如天线图案1224位于电路板1221与灯罩1222之间，以进一步增加天线图案1224的抗干扰性。进一步地，在其他一些实施方式中，电子设备10也可以不包括天线支架123，例如天线图案1224设置在壳体组件121上或者设置在电路板1221上，再例如灯罩1222进一步向壳体组件121内延伸而缩短其与指示灯1223之间的间距。
作为示例性地，结合图21，天线支架123可以包括与天线支撑部1231连接的定位柱1234和卡扣部1235，定位柱1234在天线支架123与电路板1221组装的过程中起到定位的作用，卡扣部1235使得天线支架123与电路板1221卡接固定。其中，定位柱1234和卡扣部1235的数量可以分别为多个，在多个定位柱1234分别伸入电路板1221上的定位孔内之后，多个卡扣部1235可以分别与电路板1221的不同侧边扣接，以使得天线支架123与电路板1221之间的连接更加可靠。值得注意的是：由于视角的关系，使得图21仅分别示意出了一个定位柱1234和卡扣部1235。相应地，天线支架123与电路板1221卡接固定时，金属弹性件1225同时与天线图案1224电接触。
作为示例性地，结合图12、图15及图17，壳体组件121可以包括与仓体1211连接的端盖12121，天线支架123和电路板1221可以一同沿插入方向(例如图15及图17中箭头D6所示的方向)并经由仓体1211的敞口端至少部分插入仓体1211内，端盖12121进一步与仓体1211的敞口端连接，以使得电路板1221和天线支架123及其上的结构部件位于壳体组件121内。如此，由于灯罩1222与天线支架123为两个单独的结构部件，他们及其相关的结构部件可以按照一定的组装顺序组装在一起，使得电子设备10在组装过程中不会存在因结构干涉而难以组装的技术问题。相应地，导光部1232在天线支架 123和电路板1221装配到位之后位于指示灯1223与灯罩1222之间。
类似地，端盖12121可以部分伸入仓体1211内，并可以支撑在仓体1211的敞口端的内侧的第三环状承台上。其中，端盖12121和仓体1211彼此重叠的部分可以设置有卡扣结构，以使得两者卡接固定；前述第三环状承台上可以设有容胶槽，以使得端盖12121与前述第三环状承台胶接固定，这样有利于增加端盖12121和仓体1211连接的可靠性。进一步地，壳体组件121可以包括包覆在端盖12121外侧的柔性覆层12122，柔性覆层12122的外表面与仓体1211的外表面可以平齐，以填补端盖12121与仓体1211之间的段差。其中，柔性覆层12122的硬度可以小于端盖12121的硬度。值得注意的是：柔性覆层12122和柔性覆层1114可以为注塑成型的一体结构件。
作为示例性地，结合图12及图18，仓体1211的侧壁上可以设置有阶梯孔1213，灯罩1222组装在阶梯孔1213内。其中，灯罩1222可以包括一体连接的第一透光部12221和第二透光部12222，第一透光部12221的径向尺寸小于第二透光部12222的径向尺寸；阶梯孔1213可以包括彼此连通的第一孔段和第二孔段，第一孔段的径向尺寸小于第二孔段的径向尺寸，第一孔段在法线方向D5上相较于第二孔段更靠近电路板；第一透光部12221嵌入第一孔段内，第二透光部12222嵌入第二孔段内，并支撑在阶梯孔1213的阶梯面上。换言之，灯罩1222可以沿由外至内的组装方向组装在阶梯孔1213内，有利于避免灯罩1222在外力作用下侵入仓体1211内，以维持灯罩1222与仓体1211之间的相对位置关系。
作为示例性地，结合图12、图18及图21，电子设备10可以包括与壳体组件121连接的滑动键组件124，滑动键组件124在外力作用下能够沿滑动方向(例如图12中箭头D7所示的方向)拨动设置在电路板1221上的拨动开关1226，以扩展电子设备10的控制功能，例如用于实现电子设备10的开机/关机。其中，滑动键组件124可以经由壳体组件121上的滑槽1214从壳体组件121的外侧伸入壳体组件121的内侧，并进一步经由天线支架123上的避让槽1236与拨动开关1226连接，以使得用户能够通过滑动键组件124拨动拨动开关1226。进一步地，部分滑动键组件124可以限位在天线支架123与壳体组件121之间，既可以避免滑动键组件124在外力作用下侵入壳体组件121内，又可以避免滑动键组件124与壳体组件121分离。
作为示例性地，结合图12、图18至图21，滑动键组件124可以包括转接架1241和滑动键1242，滑动键1242可以通过转接架1241与拨动开关1226连接，并用于接收用户施加的外力，以拨动拨动开关1226。其中，转接架1241设置在壳体组件121内，并经由避让槽1236从天线支架123的一侧延伸至天线支架123的另一侧，进而与拨动开关1226连接；滑动键1242经由滑槽1214从壳体组件121的外侧伸入壳体组件121的内侧，进而与转接架1241连接。简而言之，滑动键1242与转接架1241可装配连接。如此，由于转接架1241和滑动键1242为两个单独的结构部件，他们及其相关的结构部件可以按照一定的组装顺序组装在一起，使得电子设备10在组装过程中不会存在因结构干涉而难以组装的技术问题。相应地，转接架1241的一部分可以限位在天线支架123与壳体组件121之间，以在滑动键组件124与壳体组件121等结构部件组装之后阻碍滑动键组件124与壳体组件121分离。当然，在其他一些实施方式中，为了阻碍滑动键组件124与壳体组件121分离，例如滑动键1242的一部分限位在壳体组件121朝向电路板1221的内侧，再例如设置一额外的独立于滑动键1242的卡环或者插销等限位件，前述限位件与滑动键1242装配之后限位在壳体组件121朝向电路板1221的内侧；为了滑动键组件124拨动拨动开关1226，滑动键组件124也可以不包括转接架1241，例如后文中提及的第二接插部12422与拨动开关1226连接。
作为示例性地，结合图12、图18至图21，转接架1241可以包括环状主体部12411和与环状主体部12411连接的第一接插部12412，环状主体部12411位于天线支架123背离电路板1221的一侧，第一接插部12412穿过避让槽1236与拨动开关1226连接；滑动键1242可以包括操作部12421、与操作部12421连接的第二接插部12422和与第二接插部12422连接的卡合部12423，操作部12421位于壳体组件121的外侧，以便于接收用户施加的外力，第二接插部12422穿过滑槽1214而伸入环状主体部12411的插槽12413内，卡合部12423与环状主体部12411朝向电路板1221的一侧卡接，也即卡合部12423位于环状主体部12411朝向电路板1221的一侧，以使得滑动键1242与转接架1241卡接固定。当然，在其他一些实施方式中，为了实现滑动键1242与转接架1241卡接固定，滑动键1242也可以不包括卡合部12423，例如设置一额外的独立于滑动键1242的卡环或者插销等限位件，前述限位件与滑动键1242装配之后位于转接架1241朝向电路板1221的一侧。
在一些实施方式中，环状主体部12411在滑动方向D7上的长度可以大于避让槽1236在滑动方向D7上的长度，以使得环状主体部12411能够被限位在天线支架123与壳体组件121之间。
在一些实施方式中，环状主体部12411在垂直于滑动方向D7和接插方向的方向上的宽度可以大于避让槽1236在垂直于滑动方向D7和前述接插方向的方向上的宽度，以使得环状主体部12411能够被限位在天线支架123与壳体组件121之间。其中，前述接插方向可以定义为滑动键1242与转接架1241 接插连接的组装方向，例如前述接插方向平行于第二接插部12422的延伸方向。
由于环状主体部12411的长度可以大于避让槽1236的长度，环状主体部12411的宽度可以大于避让槽1236的宽度，使得环状主体部12411能够支撑在天线支架123上，尤其是滑动键1242沿上述组装方向与转接架1241接插连接的过程中，以简化组装工艺。其中，结合图12及图21，天线支架123背离电路板1221的一侧可以设置有限位槽1237，避让槽1236设置在限位槽1237的底部，环状主体部12411可以至少部分位于限位槽1237内，这样有利于减小壳体组件121在法线方向D5上的尺寸。
作为示例性地，结合图12、图19及图20，第二接插部12422和卡合部12423可以沿滑动方向D7间隔设置两组，且两个卡合部12423至少部分分别位于两个第二接插部12422的相背两侧，以便于滑动键1242与转接架1241卡接固定，且有利于避免滑动键1242与转接架1241发生相对运动。相应地，插槽12413在滑动方向D7上的尺寸可以大于插槽12413在垂直于滑动方向D7和上述接插方向的方向上的尺寸。其中，插槽12413背离电路板1221的一侧可以设置有第一导向面12414，卡合部12423可以设置有第二导向面12424。如此，在滑动键1242伸入转接架1241的过程中，第二导向面12424和第一导向面12414彼此配合使得两组第二接插部12422和卡合部12423彼此靠拢，从而使得两个卡合部12423穿过插槽12413；相应地，两个卡合部12423穿过插槽12413之后，两组第二接插部12422和卡合部12423之间的相对位置可以恢复至滑动键1242与转接架1241组装之前的状态，以使得两个卡合部12423在滑动键1242伸入转接架1241的反方向上被环状主体部12411止挡，从而实现滑动键1242与转接架1241的卡合固定。当然，在一些实施方式中，第二接插部12422和卡合部12423也可以仅设置一组，并可以通过一卡环维持滑动键1242与转接架1241之间的相对固定。
作为示例性地，结合图12及图17，拨动开关1226的开关柄的延伸方向可以垂直于法线方向D5，这样有利于减小壳体组件121在法线方向D5上的尺寸。相应地，结合图20，第一接插部12412的数量可以为两个，两个第一接插部12412在滑动方向D7上间隔设置，拨动开关1226的开关柄卡入两个第一接插部12412之间，以使得转接架1241与拨动开关1226的开关柄卡接固定，从而便于滑动键1242通过转接架1241拨动拨动开关1226。当然，在一些实施方式中，第一接插部12412的数量也可以为一个，拨动开关1226的开关柄上可以设置有孔洞，以允许第一接插部12412部分伸入前述孔洞内，同样可以使得第一接插部12412与拨动开关1226的开关柄连接。
作为示例性地，结合图12及图13，操作部12421朝向电路板1221的内侧可以设置有环绕滑槽1214的密封槽12425，滑动键组件124可以包括设置在密封槽12425内的密封圈1243，以对滑槽1214进行密封。除此之外，由于密封圈1243具有一定的压缩量，使得密封圈1243还可以在用户操作滑动键1242的过程中提供一定的阻尼，有更好的滑动手感。其中，图12及图13所示的密封圈1243为其压缩之前的形态，其压缩之后具有一定的形变量，以弹性支撑在滑动键1242与壳体组件121之间，并实现对滑槽1214良好的密封效果。当然，在其他一些实施方式中，密封槽12425也可以设置在壳体组件121上。
由于密封圈1243弹性支撑在操作部12421与壳体组件121之间，使得转接架1241能够压持在壳体组件121上，以避免滑动键组件124相对于壳体组件121晃动。其中，结合图20，转接架1241可以包括设置在环状主体部12411背离电路板1221一侧的滑动筋12415，转接架1241通过滑动筋12415滑动支撑在壳体组件121上，以减小转接架1241与壳体组件121之间的接触面积，从而减小滑动键组件124相对于壳体组件121滑动时的摩擦阻力。
在一些实施方式中，滑动筋12415的数量可以为多个，例如图20所示的两个，多个滑动筋12415可以呈条状，在垂直于滑动方向D7和上述接插方向的方向上分别位于插槽12413的两侧，每一滑动筋12415可以沿滑动方向D7延伸。
在一些实施方式中，滑动筋12415可以呈环状设置，并环绕插槽12413。
作为示例性地，结合图12、图13及图18，壳体组件121的外侧可以设置有凹陷区1215，滑槽1214设置在凹陷区1215的底部，操作部12421可以至少部分位于凹陷区1215内，这样有利于减小电子设备10在法线方向D5上的尺寸。
在一些实施方式中，在滑动键组件124沿滑动方向D7相对于壳体组件121滑动至拨动开关1226处于打开状态或者关闭状态之后，操作部12421能够被凹陷区1215的侧壁止挡，以避免滑动键组件124过拨。
在一些实施方式中，在滑动键组件124沿滑动方向D7相对于壳体组件121滑动至拨动开关1226处于打开状态或者关闭状态之后，环状主体12411能够被限位槽1237的侧壁止挡，以避免滑动键组件124过拨。
作为示例性地，结合图12及图13，凹陷区1215的底部在与凹陷区1215的侧壁连接的位置处环设有环形槽位1216，以消除凹陷区1215的底部与侧壁之间拐角处的R角，尤其是壳体组件121通过注塑工艺制作时。其中，电子设备10可以包括贴设在凹陷区1215的底部的垫片1244，垫片1244覆盖环形 槽位1216，且垫片1244的边缘悬空设置在环形槽位1216的上方，以允许垫片1244平整地贴设，避免垫片1244的边缘翘起。相应地，滑动键组件124可以支撑在垫片1244上。除此之外，由于垫片1244的边缘不会翘起，使得滑动键组件124能够沿滑动方向D7滑动到位。例如：在滑动键组件124沿滑动方向D7相对于壳体组件121滑动至拨动开关1226处于打开状态或者关闭状态之后，操作部12421的边缘位于环形槽位1216的上方。
进一步地，环形槽位1216远离滑槽1214的外侧壁可以与凹陷区1215的侧壁平齐。
在一些实施方式中，垫片1244上可以设置有用于指示拨动开关1226的打开状态或者关闭状态的文字、颜色、符号等指示信息，例如文字“ON”和“OFF”分别指示打开状态和关闭状态，再例如绿色和红色分别指示打开状态或者关闭状态。其中，前述指示信息可以设置在垫片1244朝向凹陷区1215的底部的内侧，以避免前述指示信息被磨掉。当然，前述指示信息也可以设置在凹陷区1215的底部上。
在一些实施方式中，垫片1244可以用于调节密封圈1243在滑动键组件124沿滑动方向D7相对于壳体组件121滑动的过程中产生的阻尼。
作为示例性地，结合图12及图18，阶梯孔1213、滑槽1214和凹陷区1215等可以位于仓体1211的同一侧壁上，使得滑动键组件124和灯罩1222位于电路板1221的同一侧，以便于用户在佩戴状态下操作滑动键组件124。
作为示例性地，结合图12及图14，电子设备10包括设置在壳体组件121内的第三麦克风1251，第三麦克风1251可以拾取环境声、用户语音等声音中的至少一者。其中，壳体组件121上可以设置有拾音通道1217，第三麦克风1251用于拾取经由拾音通道1217传入的声音。进一步地，拾音通道1217可以包括彼此连通的第一通道段12171和第二通道段12172。本申请一些实施方式中，第一通道段12171和第二通道段12172连通，并通过第一通道段12171和第二通道段12172连通壳体组件121内部与外界。其中，第一通道段12171相较于第二通道段12172更靠近第三麦克风1251，第一通道段12171的第一中轴线与第二通道段12172的第二中轴线可以不重合。如此，第一通道段12171和第二通道段12172彼此错位，有利于避免外界的液滴等直接冲击第三麦克风1251，从而延长第三麦克风1251的使用寿命。
本申请的其它一些实施方式中，拾音通道1217可以包括三个或者更多个通道段，该三个或者更多个通道段相互连通并连通壳体组件121内部与外界。
进一步地，电子设备10可以包括设置在壳体组件121内的防护网1252，防护网1252盖设在第一通道段12171上。如此，有利于进一步避免外界的液滴等直接冲击第三麦克风1251，从而延长第三麦克风1251的使用寿命。其中，上述第一中轴线和上述第二中轴线可以分别垂直于防护网1252。
作为示例性地，结合图12及图14，第一通道段12171在防护网1252上的的正投影和第二通道段12172在防护网1252上的正投影可以部分重叠，以便于第一通道段12171的第一中轴线与第二通道段12172的第二中轴线不重合。
进一步地，第二通道段12172在垂直于上述第一中轴线的参考平面上的横截面积可以大于第一通道段12171在垂直于上述第二中轴线的参考平面上的横截面积，例如第一通道段12171和第二通道段12172分别为圆柱形孔且前者的孔径小于后者的孔径。如此，拾音通道1217大致呈喇叭状，以使得更多的声音进入拾音通道1217，且被更好地汇集之后进入第三麦克风1251。
需要说明的是：在通过诸如注塑工艺的方式制作壳体组件121的过程中，可以通过两个型芯分别在壳体组件121上形成第一通道段12171和第二通道段12172，且两个型芯的脱模方向彼此反向，以便于得到横截面积大小不一的第一通道段12171和第二通道段12172。
在一些实施方式中，第一通道段12171在防护网1252上的正投影和第二通道段在防护网1252上的正投影之间的重叠区域具有一重叠面积，第一通道段12171在防护网1252上的正投影具有一投影面积，前述重叠面积与前述投影面积之间的比值可以介于0.4与0.6之间。其中，如果前述比值太小，容易导致第一通道段12171与第二通道段12172之间的连通面积过小而不利于声音经由拾音通道1217进入第三麦克风1251；如果前述比值太大，容易导致第三麦克风1251被外界的液滴等直接冲击的风险增加。
在一些实施方式中，上述第一中轴线和上述第二中轴线可以平行设置，以使得壳体组件121的壁厚更加均匀，避免局部过薄。其中，结合图14，第一通道段12171和第二通道段12172在上述第一中轴线上部分重叠，第一通道段12171和第二通道段12172重叠部分的尺寸(例如|h1-h2|)与第一通道段12171的深度(例如图14中h1)和第二通道段12172的深度(例如图14中h2)中较小者之间的比值可以介于0.5与0.8之间。其中，如果前述比值太小，容易导致第一通道段12171与第二通道段12172之间的连通面积过小而不利于声音经由拾音通道1217进入第三麦克风1251；如果前述比值太大，容易导致壳体组件121的局部过薄。可以理解的是，一些其它实施方式中，上述第一中轴线和上述第二中轴线也可以呈角度设置，能够在壳体组件121的壁厚一定的情况下，调整拾音通道1217的长度。
作为示例性地，结合图12、图15及图17，壳体组件121具有彼此正交的第一方向、第二方向和第 三方向，壳体组件121可以包括在前述第一方向上彼此扣合的仓体1211和端盖12121，壳体组件121在前述第二方向上的尺寸可以大于壳体组件121在前述第三方向上的尺寸。其中，基于上述的相关描述，前述第一方向、第二方向和第三方向可以分别平行于插入方向D6、滑动方向D7和法线方向D5。换言之，壳体组件121设置成扁平结构，这样有利于减小壳体组件121在法线方向D5上的尺寸。
作为示例性地，结合图17，仓体1211具有在上述第二方向上彼此间隔的第一内壁12111和第二内壁12112，第一内壁12111在上述第一方向上的尺寸可以小于第二内壁12112在上述第一方向上的尺寸，也即仓体1211在上述第一方向上的深度并不是处处相等，而是存在一定的差异。其中，防护网1252可以固定在第一内壁12111上，第三麦克风1251固定在防护网1252上。如此，由于第三麦克风1251、防护网1252等相关结构设置在仓体1211内深度较浅的位置，使得电子设备10的组装难度更低。相应地，拾音通道1217可以设置在仓体1211的侧壁上。
进一步地，第一内壁12111上可以形成有内陷区12113，拾音通道1217与内陷区12113的底部连通。其中，防护网1252可以通过双面胶或者胶水等胶体固定在内陷区12113的底部，第三麦克风1251可以至少部分位于内陷区12113内，并可以通过双面胶或者胶水等胶体固定在防护网1252，以增加第三麦克风1251的抗跌落能力。类似地，第三麦克风1251可以借助表面贴装技术贴设在柔性电路板1253上，进而与电路板1221连接。
作为示例性地，第一内壁12111可以相较于第二内壁12112更加靠近支撑组件12的中间位置，也即更加远离机芯模组11，且在佩戴状态下，拾音通道1217可以指向脑后，这样有利于增加第三麦克风1251的抗干扰能力。
需要说明的是：对于拾音通道1217的相关改进，也可以应用在壳体组件111上设置的分别与第一麦克风1161和第二麦克风1162配合的拾音孔上，在此不再赘述。
作为示例性地，结合图15、图17及图18，电子设备10可以包括与壳体组件121连接的按键组件126，按键组件126在外力作用下能够沿按压方向(例如图图17中箭头D8所示的方向)按压电路板1221上的轻触开关1227，以扩展电子设备10的控制功能，例如用于实现电子设备10的开机/关机，再例如用于实现电子设备10的音量加/减。其中，壳体组件121的外侧可以设置有凹陷区1218，凹陷区1218的底部设置有按键通孔1219；按键组件126可以部分位于凹陷区1218内，并经由按键通孔1219伸入壳体组件121内，以接近轻触开关1227。
在一些实施方式中，按键组件126的数量可以为两个，其中一个至少用于实现电子设备10的音量加，另一个至少用于实现电子设备10的音量减。例如：两个按键组件126分别用于实现电子设备10的音量加/减，其中一个按键组件126进一步复用实现电子设备10的开机/关机。其中，结合图17及图18，两个按键组件126可以分别设置在各自的凹陷区1218内，且两个凹陷区1218间隔设置，并分别经由各自的按键通孔1219伸入壳体组件121内，以使得两个按键组件126彼此独立而不相互干扰。相应地，轻触开关1227的数量也可以为两个，并与两个按键组件126分别一一对应设置。
在一些实施方式中，按键组件126的数量可以为一个，例如用于实现电子设备10的开机/关机。
作为示例性地，结合图15、图17及图18，按键组件126可以包括按键1261和密封圈1262，按键1261可以部分位于凹陷区1218内，并经由按键通孔1219伸入壳体组件121内，以允许按键组件126在外力作用下沿按压方向D8按压轻触开关1227，密封圈1262可以位于凹陷区1218内，并环绕按键通孔1219，以对按键通孔1219进行密封。除此之外，由于密封圈1262具有一定的压缩量，使得密封圈1262还可以在用户操作按键1261的过程中提供一定的阻尼及回弹手感。其中，图17所示的密封圈1262为其压缩之前的形态，其压缩之后具有一定的形变量，以弹性支撑在按键1261与壳体组件121之间。当然，在其他一些实施方式中，按键1261朝向壳体组件121的一侧可以设置有用于容纳密封圈1262的密封槽。
作为示例性地，结合图17、图18及图22，按键1261可以包括操作部12611、与操作部12611连接的接插柱12612和与接插柱12612连接的卡扣部12613，操作部12611可以至少部分位于凹陷区1218内，并支撑在密封圈1262上，接插柱12612穿过密封圈1262和按键通孔1219伸入壳体组件121内，卡扣部12613与壳体组件121的内侧壁卡合，也即卡扣部12613位于壳体组件121朝向电路板1221的内侧，以使得按键1261与壳体组件121卡接固定。此时，密封圈1262可以具有一压缩量，进而在按键1261与凹陷区1218的底部之间提供密封，也即按键1261与壳体组件121连接时即可同时压持密封圈1262，从而增加电子设备10在按键通孔1219处的密封性，简单、可靠。当然，在其他一些实施方式中，为了实现按键1261与壳体组件121卡接固定，按键1261也可以不包括卡扣部12613，例如设置一额外的独立于按键1261的卡环或者插销等限位件，前述限位件与按键1261装配之后位于壳体组件121朝向电路板1221的内侧。
作为示例性地，结合图17及图22，接插柱12612可以呈筒状设置，接插柱12612背离操作部12611 的一端可以设置有至少两个分别沿接插柱12612的轴向延伸的开槽12614，例如图22所示的两个，开槽12614可以将接插柱12612沿接插柱12612的轴向划分成靠近操作部12611的第一柱段12615和远离操作部12611的第二柱段12616。其中，第一柱段12615沿接插柱12612的周向连续设置，密封圈1262套设在第一柱段12615上，以便于密封圈1262对按键通孔1219进行密封；第二柱段12616具有沿接插柱12612的周向间隔设置的接插臂(图17及图22中未标注)，卡扣部12613的数量与前述接插臂的数量相同并一一对应连接。
进一步地，按键通孔1219背离电路板1221的一侧可以设置有第一导向面(图17及图18中未标注)，卡扣部12613可以设置有第二导向面12617。如此，在按键1261伸入壳体组件121的过程中，第二导向面12617和前述第一导向面彼此配合使得上述接插臂彼此靠拢，从而使得卡扣部12613穿过按键通孔1219。
作为示例性地，结合图17，按键组件126可以包括与按键1261连接的弹性转接件1263，弹性转接件1263的硬度小于按键1261的硬度，按键1261通过弹性转接件1263按压轻触开关1227，从而在用户操作按键1261的过程中提供一定的阻尼及回弹手感。其中，按键1261的材质可以为聚碳酸酯或其中混有玻璃纤维、碳纤维中的至少一种，弹性转接件1263的材质可以为硅胶、橡胶等。进一步地，弹性转接件1263的一部分可以插入第二柱段12616，另一部分则凸出于按键1261朝向轻触开关1227的一端，以使得按键1261通过弹性转接件1263按压轻触开关1227。
作为示例性地，结合图17及图18，凹陷区1218可以包括第一子凹陷区12181和第二子凹陷区12182，第一子凹陷区12181在按压方向D8上相较于第二子凹陷区12182更靠近电路板1221，第二子凹陷区12182在垂直于按压方向D8的方向上的尺寸大于第一子凹陷区12181在垂直于按压方向D8的方向上的尺寸。简而言之，凹陷区1218在按压方向D8上划分处两个子区域，按键通孔1219设置在第一子凹陷区12181的底部。其中，密封圈1262可以部分位于第一子凹陷区12181内，操作部12611可以至少部分位于第二子凹陷区12182内。如此，在按键1261沿按压方向D8相对于壳体组件121运动的过程中，操作部12611能够被第二子凹陷区12182的底部止挡，以避免按键1261过按以及密封圈1262的形变量过大，从而控制按键1261的行程以及延长密封圈1262的使用寿命。
进一步地，在平行于按压方向D8的参考截面上，第一子凹陷区12181的侧壁可以至少部分呈弧形设置，以使得第一子凹陷区12181的底部与其侧壁之间弧形过渡，从而减小(甚至是消除)密封圈1262与壳体组件121之间的间隙，进而增加密封圈1262对按键通孔1219的密封效果。
作为示例性地，结合图15至图18及图22，凹陷区1218内可以设置有第一限位结构1271，第一限位结构1271位于密封圈1262的外侧，操作部12611上可以设置有第二限位结构1272。其中，在按键组件126未受外力作用的非按压状态下，第一限位结构1271和第二限位结构1272可以在按压方向D8上部分重叠，并彼此配合以在按键通孔1219的周向上对按键1261进行限位。如此，有利于维持按键1261与壳体组件121在按键通孔1219的周向上的相对位置，从而避免操作部12611与壳体组件121在按键通孔1219的径向上的间隙多小或者过大。除此之外，在按键1261沿按压方向D8相对于壳体组件121运动的过程中，操作部12611能够被第一限位结构1271止挡，和/或，第二限位结构1272能够与壳体组件121抵接，以避免按键1261过按以及密封圈1262的形变量过大，从而控制按键1261的行程以及延长密封圈1262的使用寿命。
作为示例性地，结合图15至图18及图22，第一限位结构1271可以包括两个在按键通孔1219的周向上间隔设置的第一限位块12711，以及设置在凹陷区1218的底部且位于两个第一限位块12711之间的盲孔12712；第二限位结构1272可以包括凹槽12721和部分位于凹槽12721内的第二限位块12722，凹槽12721使得操作部12611局部减薄。其中，在上述非按压状态下，第二限位块12722位于两个第一限位块12711之间；按键组件126在受外力作用的按压状态下，第二限位块12722伸入盲孔12712内，两个第一限位块12711分别伸入凹槽12721内。如此，不仅可以在按键通孔1219的周向上对按键1261进行限位，还有利于在按键组件126具有预设的行程时减小壳体组件121在按压方向D8上的尺寸。相应地，第一限位块12711可以位于第二子凹陷区12182内，盲孔12712可以延伸至第一子凹陷区12181的底部，以使得盲孔12712的深度足够的大，从而使得按键组件126具有足够的行程。
在一些实施方式中，两个第一限位块12711在按键通孔1219的周向上的间距可以大于盲孔12712在按键通孔1219的周向上的孔径，盲孔12712靠近第一限位块12711的边缘设置有导向弧面或者导向斜面，以便于第二限位块12722伸入盲孔12712内。
在一些实施方式中，两个第一限位块12711在按键通孔1219的周向上的间距可以等于盲孔12712在按键通孔1219的周向上的孔径，以便于第二限位块12722伸入盲孔12712内。
作为示例性地，结合图15至图18及图22，第一限位结构1271和第二限位结构1272的数量可以分别为两个，两个第一限位结构1271和第二限位结构1272分别在按键通孔1219的径向上相对间隔设 置。如此，不仅有利于进一步维持按键1261与壳体组件121在按键通孔1219的周向上的相对位置，还有利于使得按键1261的行程被控制地更加平稳。
作为示例性地，结合图15、图17及图18，凹陷区1218和按键通孔1219等可以位于仓体1211与端盖12121相对的底部，使得按键组件126等结构部件固定在仓体1211的底部，以便于用户在佩戴状态下操作按键组件126。当然，在其他一些实施方式中，仓体1211的底部与端盖12121之间的相对位置可以互换，使得凹陷区1218和按键通孔1219等可以设置在端盖12121上，也即按键组件126等结构部件可以固定在端盖12121上。
基于上述的相关描述，壳体组件121可以作为支撑组件12的一部分，并可以用于容纳电路板1221、电池等相关的结构部件。其中，结合图1，壳体组件121的数量可以为两个，其中一个可以用于容纳电路板1221，另一个则可以用于容纳前述电池。相应地，机芯模组11和前述电池等结构部件可以与电路板1221电性连接。
