具体实施方式
为了更清楚地说明本申请的实施例的技术方案，下面将对实施例描述中所需要使用的附图作简单的介绍。显而易见地，下面描述中的附图仅仅是本申请的一些示例或实施例，对于本领域的普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图将本申请应用于其他类似情景。应当理解，给出这些示例性实施例仅仅是为了使相关领域的技术人员能够更好地理解进而实现本发明，而并非以任何方式限制本发明的范围。除非从语言环境中显而易见或另做说明，图中相同标号代表相同结构或操作。
如本申请和权利要求书中所示，除非上下文明确提示例外情形，“一”、“一个”、“一种”和/或“该”等词并非特指单数，也可包括复数。一般说来，术语“包括”与“包含”仅提示包括已明确标识的步骤和元素，而这些步骤和元素不构成一个排它性的罗列，方法或者设备也可能包含其他的步骤或元素。术语“基于”是“至少部分地基于”。术语“一个实施例”表示“至少一个实施例”；术语“另一实施例”表示“至少一个另外的实施例”。其他术语的相关定义将在下文描述中给出。以下，不失一般性，在描述本发明中发声装置时，将采用“扬声装置”或“耳机”的描述。该描述仅仅为发声装置的一种形式，对于该领域的普通技术人员来说，“扬声装置”或“耳机”也可用其他同类词语代替，比如“播放器”、“扬声器装置”“助听器”等。事实上，本发明中的各种实现方式可以很方便地应用到其它非扬声器类的听力设备上。例如，对于本领域的专业人员来说，在了解扬声装置的基本原理后，可能在不背离这一原理的情况下，对实施扬声装置的具体方式与步骤进行形式和细节上的各种修正和改变，特别地，在扬声装置中加入环境声音拾取和处理功能，使该扬声装置实现助听器的功能。例如，麦克风等传声器可以拾取使用者/佩戴者周围环境的声音，在一定的算法下，将声音处理后(或者产生的电信号)传送至扬声装置部分。即扬声装置可以经过一定的修改，加入拾取环境声音的功能，并经过一定的信号处理后通过扬声装置将声音传递给使用者/佩戴者，从而实现助听器的功能。需要知道的是，本申请中的扬声装置可以是气传导扬声装置或者骨传导扬声装置。气传导扬声装置产生的声音可以通过空气的振动传递到人耳中，而骨传导扬声装置产生的声音可以通过骨头(例如，人的颅骨)传递给人的听觉 声音。除非特别说明，本申请中的描述不限制扬声装置传递声音的方式，即既可以是骨传导的方式，也可以是气传导的方式。
本申请披露了一种扬声装置。所述扬声装置可以具有任意可能的形状和结构，例如，可以包括但不限于耳机、带有声音播放功能的眼镜、头带、头盔等。参阅图1和图2，图1是本申请中一些实施例提供的扬声装置的结构示意图；图2是本申请中一些实施例提供的扬声器组件的结构示意图。
如图1所示，扬声装置可以包括支撑连接件10和设置于支撑连接件10两端的扬声器组件40。
在一些实施例中，支撑连接件10可以包括两个耳挂20以及连接在两个耳挂之间的后挂30。使用时，两个耳挂20可以分别佩戴在用户的左右耳附近，后挂30可以位于用户的头部后侧。通过耳挂20与人体头部的接触，可以将该扬声装置固定在人体的头部。特别地，当扬声器组件40在振动时，耳挂20与人体头部的一个或多个接触点(例如，耳挂顶端25附近的一个或多个点)可以作为扬声器组件40在振动时的振动支点。即，扬声器组件40可以看成是围绕耳挂20与人体头部的接触点振动。
仅仅为了方便说明，扬声器组件40的振动可看成是以耳挂顶端25为固定点，耳挂顶端25与扬声器组件40之间的耳挂20的部分作为臂杆的往复摆动运动。此时，耳挂顶端25可以被叫做振动支点25。在一些实施例中，当扬声装置通过骨传导的方式传递声音时，扬声器组件40摆动的幅度(或振动加速度)与其产生的音量呈正相关。而扬声器组件40的质量分布对其往复摆动的幅度有明显影响，进而影响扬声器组件40所产生的音量。
在一些实施例中，扬声器组件40可以包括扬声器模块(图中未示出)和按键模块4d。特别的，扬声器模块可以有两个，分别位于左、右侧的两个扬声器组件40内。在一些实施例中，扬声器模块可以是扬声器组件40上除按键模块4d以外的部分，包括产生振动的耳机芯和用于支撑所述耳机芯并传递振动的机芯外壳等。
在一些实施例中，用户可以通过按键模块4d对该扬声装置进行控制。例如，用户可以按压按键模块4d实现暂停/开始、录音、接听电话等操作。
具体的，按键模块4d可以基于用户的操作指令实现不同的交互功能，例如：点击一次按键模块4d，可以实现暂停/开始(例如音乐、录音等)；快速点击两次按键模块 4d，可以实现接听电话；有规律地点击(例如，隔一秒点击一次，总共点击两次)实现录音功能。在一些实施例中，用户的操作指令可以是点击、滑动、滚动等操或其组合的操作。例如在按键模块4d的表面上下滑动，实现切换歌曲的功能。
在一个应用场景中，按键模块4d可以有至少两个，并且位于左、右侧两个扬声器组件40上。用户可以使用左、右手分别操作按键模块4d，从而实现更多的控制功能。
在一些实施例中，为了进一步提高用户的体验，可以将不同的案件功能分配到左、右两侧的按键模块4d。即，用户可以使用不同操作分别对两侧的按键模块4d进行控制。例如，对应左侧的按键模块4d：点击一次，可以开启录音功能，再点击一次，录音功能关闭；快速点击两次，可以实现暂停/播放功能。又例如，在右侧的按键模块4d上快速点击两次，可以实现接听电话功能(若此时在播放音乐且无电话通入，则可以实现切换下一首/上一首歌曲功能等)。
在一些实施例中，上述对于左、右侧按键模块4d对应的功能可以是用户自定义的。例如，用户可以通过应用软件设置，将由左侧按键模块4d执行的暂停/播放功能分配到由右侧的按键模块4d执行。又例如将由右侧按键模块4d执行的接听电话功能分配到由左侧的按键模块4d执行。进一步的，对于实现对应功能的操作指令(例如点击次数、滑动手势)，用户同样可以通过应用软件进行设置。例如，将接听电话功能对应的操作指令由点击一次设置为点击两次，将切换下一首/上一首歌曲功能对应的操作指令由点击两次设置为点击三次。用户自定义可以更符合用户操作习惯，一定程度上避免操作失误，提高用户体验。
在一些实施例中，按键模块4d的功能可以不是唯一的，而是根据用户常用的功能进行设定。例如，按键模块4d还可以实现拒接电话、语音阅读短信等功能，用户可以对于功能以及功能对应的操作指令进行自定义设置，满足不同需求。
在一些实施例中，按键模块4d的中心与振动支点25之间的距离可以不大于扬声器模块的中心与振动支点之间的距离。从而在相同的功率下，提高扬声器组件40的振动加速度，进而提高扬声器组件40振动发出的音量。需要知道的是，按键模块4d仅仅是作为在扬声器组件40上实现用户交互的一种方式，对于本领域的技术人员来说，可以将按键模块4d替换成其他能够实现类似功能的组件或结构，而这些组件或结构也仍然在本申请的保护范围内。例如，按键模块4d可以替换为一个触屏装置、语音识别 装置、压力传感器，或类似的，或其中一种或多种的组合。
在一些实施例中，按键模块4d的中心可以是质心m1或者形心g1，按键模块4d的质心m1或形心g1与耳挂顶端25(也即振动支点)之间具有第一距离l1，扬声器模块(扬声器组件40除按键模块4d的其余部分)的质心m2或形心g2与耳挂顶端25之间具有第二距离l2。需注意的是，上述扬声器模块的质心或形心，也可以替换为机芯壳体的质心或形心。
在一些实施例中，按键模块4d与扬声器模块的质量分布较为均匀，因此，可认为按键模块4d的质心m1与形心重合，扬声器模块的质心m2与形心g2也重合。
在一些实施例中，按键模块4d在扬声器组件40内的质量分布与第一距离l1与第二距离l2之间的比例，以及按键模块4d的质量与扬声器模块的质量比k有关。
具体地，由动力学原理可以得出按键模块4d设置于距离耳挂顶端25的远端4h时，扬声器组件40的振动加速度会小于按键模块4d设置于距离耳挂顶端25的近端4g时的振动加速度，从而造成音量下降。在按键模块4d的质量一定的情况下，随着第一距离l1与第二距离l2之间的比例的增加，扬声器组件40的振动加速度减小，进而导致音量减小；而在第一距离l1与第二距离l2之间的比例一定的情况下，随着按键模块4d质量的增加，扬声器组件40的振动加速度减小，进而导致音量降低。因此，可通过调节第一距离l1与第二距离l2之间的比例以及按键模块4d的质量与扬声器模块的质量比k，而将按键模块4d的设置而导致扬声器组件40的音量降低控制在人耳所能够识别的范围之内。
在一些实施例中，第一距离l1与第二距离l2之间的比例可以不大于1。
具体地，在第一距离l1与第二距离l2之间的比例等于1时，按键模块4d的质心m1或形心g1与扬声器模块的质心m2或形心g2重合，从而使得该按键模块4d相对于扬声器组件40居中设置；在第一距离l1与第二距离l2之间的比例小于1时，按键模块4d的质心m1或形心g1相对于扬声器模块的质心m2或形心g2更靠近耳挂顶端25的位置，从而设置于扬声器组件40靠近耳挂顶端25的近端。而且第一距离l1与第二距离l2之间的比例越小，则按键模块4d的质心m1或形心g1相对于扬声器模块的质心m2或形心g2更靠近耳挂顶端25。
在一些实施例中，第一距离l1与第二距离l2之间的比例可以不大于0.95，从而 使得按键模块4d更靠近于耳挂顶端25。其中，第一距离l1与第二距离l2之间的比例还可以为0.9、0.8、0.7、0.6、0.5等。在一些实施例中，第一距离l1与第二距离l2之间的比例可以在0.4和0.95之间，或者0.5到0.95之间，或者0.7到0.95之间，或者0.8到0.9之间。
进一步地，在第一距离l1与第二距离l2之间的比例满足上述范围的情况下，按键模块4d的质量与扬声器模块的质量比可不大于0.3，具体还可以不大于0.29、0.23、0.17、0.1、0.06、0.04等，此处不做限定。
需要额外注意的是，上述一个或多个实施例中，按键模块4d的质心m2可以和形心g2(图中未示出)重合，即位于同一点。扬声器模块的质心m2与形心g2(图中未示出)重合，位于同一点的前提条件是按键模块4d以及扬声器模块的质量分布较为均匀。
在另一些实施例中，按键模块4d的质心m1和形心g1可以不重合。考虑到按键模块4d的结构比较简单且规则，其形心g1更容易获得，所以可以选用形心按键模块4d的形心g1作为中心。当扬声器模块的质心m2与形心g2也不重合时，但由于扬声器模块中的结构所采用的材料不同(如麦克风、软性电路板、焊盘等均采用不同的材料制作)，质量分布不均匀，且各零部件形状不规则(如麦克风、软性电路板、焊盘等)。为方便起见，可以将扬声器模块的质心m2作为中心。在一些实施例中，扬声器模块和按键模块的中心可以根据不同的方式确定，例如同时选择形心作为各自的中心，同时选择质心作为各自的中心，或者一个选择形心，另一个选择质心作为各自的中心等。
例如，在一个应用场景中，按键模块4d的形心g1与耳挂顶端25之间具有第一距离l1，扬声器模块的质心m2与耳挂顶端25之间具有第二距离l2。按键模块4d在扬声器组件40内的质量分布与第一距离l1与第二距离l2之间的比例，以及按键模块4d的质量与扬声器模块的质量比k有关。具体地，在按键模块4d质量一定的情况下，随着第一距离l1与第二距离l2之间的比例的增加，扬声器组件40在相同驱动力下的振动加速度减小，进而导致音量减小；而在第一距离l1与第二距离l2之间的比例一定的情况下，随着按键模块4d质量的增加，扬声器组件40在相同驱动力下的振动加速度减小，进而导致音量降低。因此，可通过调节第一距离l1与第二距离l2之间的比例以及按键模块4d的质量与扬声器模块的质量比k，而将由于按键模块4d的设置而导致的音 量降低控制在一定的范围之内。
进一步地，当以按键模块4d的形心g1和扬声器模块的质心m2作为参照点时，仍然可以将第一距离l1与第二距离l2之间的比例设置成不大于1。
具体地，在第一距离l1与第二距离l2之间的比例等于1时，按键模块4d的形心g1与扬声器模块的质心m2重合，从而使得该按键模块4d相对于扬声器组件40居中设置；在第一距离l1与第二距离l2之间的比例小于1时，按键模块4d的形心g1相对于扬声器模块的质心m2更靠近耳挂顶端25的位置，从而设置于扬声器组件40靠近耳挂顶端25的近端4g。而且第一距离l1与第二距离l2之间的比例越小，则按键模块4d的形心g1相对于扬声器组件40的质心m2更靠近耳挂顶端25。
进一步地，第一距离l1与第二距离l2之间的比例可不大于0.95，从而使得按键模块4d更靠近于耳挂顶端25。其中，第一距离l1与第二距离l2之间的比例还可以为0.9、0.8、0.7、0.6、0.5等，具体可根据需求进行设置，此处不做限定。
再进一步地，在第一距离l1与第二距离l2之间的比例满足上述范围的情况下，按键模块4d的质量与扬声器模块的质量比可不大于0.3，具体还可以不大于0.29、0.23、0.17、0.1、0.06、0.04等，此处不做限定。
在另一实施例中，仍然可以将扬声器模块的形心g2作为参考点，此处的描述与前述实施例相似，不再赘述。
图3是本申请中一些实施例提供的扬声器组件的另一角度的结构示意图。请继续参阅图3，在一些实施例中，扬声器模块还可以包括用于产生声音的耳机芯以及用于容纳耳机芯的机芯壳体41。
在一些实施例中，机芯壳体41可以包括外侧壁412和与外侧壁412连接并环绕设置的周侧壁411。当用户佩戴扬声装置时，周侧壁411的一侧可以与人体头部接触，外侧壁412可以位于周侧壁411的远离人体头部的另一侧。在一些实施例中，机芯壳体41设置有容纳耳机芯的空腔。
在一些实施例中，周侧壁411可以包括沿外侧壁412的长度方向设置的第一周侧壁411a和沿外侧壁412的宽度方向设置的第二周侧壁411b。在一些实施例中，第一周侧壁411a和第二周侧壁411b可以均为两个，第一周侧壁411a和第二周侧壁411b可以依次围合。用户佩戴扬声器装置时，两个第一周侧壁411a分别朝向用户头部的前侧 和后侧，两个第二周侧壁411b分别朝向用户头部的上侧和下侧。
在一些实施例中，外侧壁412与周侧壁411连接在一起形成一端开口并容纳耳机芯的空腔。例如，外侧壁412可以被配置为盖设于第一周侧壁411a和第二周侧壁411b围合之后的一端，以此来形成一个一端开口、一端封闭的具有空腔的机芯壳体41。
在一些实施例中，第一周侧壁411a和第二周侧壁411b围合而成的形状可以不受限制。第一周侧壁411a和第二周侧壁411b可以围合成任意适合贴合用户头部的形状，例如：长方形，正方形，圆形，椭圆形等。
在一些实施例中，第一周侧壁411a和第二周侧壁411b围合成的形状可以符合人体工程学原理，提高用户的佩戴体验。在一些实施例中，第一周侧壁411a和第二周侧壁411b的高度可以相同，也可以不同。当依次连接的两个周侧壁411的高度不相同时，应保证周侧壁411凸出的部分不会影响用户的佩戴以及操作。
图4是本申请中扬声装置的一些实施例中表示距离h1的示意图；图5是本申请中扬声装置的一些实施例中表示距离h2的示意图；图6是本申请中扬声装置的一些实施例中表示距离h3的示意图。在一些实施例中，扬声器模块沿靠近振动支点的方向可以具有底端位置、中部位置和顶端位置。
具体的，外侧壁412盖设于第一周侧壁411a和第二周侧壁411b围合后的一端。当用户佩戴扬声器装置时，外侧壁412位于第一周侧壁411a和第二周侧壁411b的远离用户头部的一端。在一些实施例中，外侧壁412可以包括近端点和远端点，近端点和远端点可以分别位于外侧壁412与第一周侧壁411a和第二周侧壁411b连接的轮廓上，且近端点和远端点可以分别位于轮廓的相对位置。在一些实施例中，近端点是外侧壁412上与振动支点之间的距离(h1)最短的点，称为顶端位置；远端点是外侧壁412上与振动支点之间的距离(h2)最长的点，称为底端位置；另外，近端点和远端点的连线的中点与振动支点之间的距离h3可以介于h1和h2之间，称为中部位置。
在一实施例中，按键模块4d可以位于外侧壁412的中部位置；或者按键模块4d位于外侧壁412的中部位置到顶端位置之间。这里说的按键模块4d位于某特定位置指的是按键模块4d的中心位于该特定位置。
在一些实施例中，按键模块4d进一步包括：弹性承座4d1、按键4d2及按键孔4122。
在一些实施例中，机芯壳体41的内表面，具体为外侧壁412的内表面上设置有凹陷区4121，并进一步设置有位于该凹陷区4121并用于连通机芯壳体41的内表面和外表面的按键孔4122。其中，该凹陷区4121是由机芯壳体41的内表面朝向机芯壳体41的外部凹陷形成。按键孔4122可进一步设置于该凹陷区4121的中间部位，或者根据实际需求设置于其它部位在一些实施例中，弹性承座4d1包括一体成型的承座本体4d11以及支撑柱4d12。其中，承座本体设置于凹陷区4121内，并固定于凹陷区4121的底部。具体地，该凹陷区4121的底部是指凹陷区4121的远离机芯壳体41的内部的内壁面。支撑柱4d12设置于承座本体4d11朝向机芯壳体41外部的一侧，并从按键孔4122外露。
按键孔4122的形状可以不受限制，例如，圆形、方形、三角形，或者其他适于点击的形状，并且按键孔4122与按键4d2能够相互配合使得按键4d2能够安装在按键孔4122中。
在一些实施例中，该弹性承座4d1可以由软性材质制成，如软性的橡胶、硅胶等。为了提高按压手感，按键4d2可由硬质塑胶制成，并设置于支撑柱4d12外露于按键孔4122的部分上。具体地，按键4d2和支撑柱4d12可以通过粘接、注塑以及弹性抵接等方式固定在一起。
上述实施例中，弹性承座4d1设置于凹陷区4121内，并固定于凹陷区4121的底部，并通过承座本体4d11而从机芯壳体41内部一侧覆盖按键孔4122，以将机芯壳体41内部与外部隔开，从而使得机芯壳体41外部的液体难以通过按键孔4122而进入到机芯壳体41的内部，从而对机芯壳体41内部器件(如耳机芯)起到防水、保护的作用。
在一个应用场景中，弹性承座4d1可通过承座本体4d11以粘贴的方式固定于凹陷区4121的底部，具体可在承座本体323的朝向机芯壳体41外部一侧的表面与凹陷区4121的底部之间施加粘胶、双面胶等而将二者粘贴在一体。
在另一个应用场景中，承座本体323可通过注塑方式固定于凹陷区4121的底部。承座本体323的朝向机芯壳体41外部一侧的表面与机芯壳体41的凹陷区4121底部之间通过注塑而一体成型，具体可以通过包胶的方式形成。本应用场景中，通过弹性承座4d1与机芯壳体11的凹陷区4121的底部通过注塑的方式一体成型，从而使得二者 之间的结合更加牢固，增大二者之间的结合强度并能够提高机芯壳体41的密封性，从而一方面能够使得整个按键模块4d更加稳定、牢靠，另一方面能够进一步提高机芯壳体41的防水效果。
在一实施例中，承座本体4d11包括环形固定部4d111及弹性支撑部4d112。其中，该环形固定部4d111绕按键孔4122设置并与凹陷区4121的底部贴合固定，从而将弹性承座4d1与机芯壳体41固定在一起。
弹性支撑部4d112与环形固定部4d111的内环面连接且朝向机芯壳体41的外部呈穹顶形隆起，从而使得其顶部到底部之间在按键4d2的按压方向上具有一定的高度，且其顶部沿垂直于按压方向上的尺寸小于底部。其中，支撑柱4d12设置于弹性支撑部4d112的顶部。在按键4d2受到按压时，该弹性支撑部4d112的顶部受到按压而朝向靠近其底部的方向运动，进而带动按键4d2朝向按键孔4122的方向运动直至触发按键开关431。
需要指出的是，由于扬声装置的整体结构较小，各部件之间连接较为紧密，从而使得按键4d2到按键开关431之间的按压行程较小，从而减弱对按键4d2的按压触感。本实施方式中，由于弹性支撑部4d112朝向机芯壳体41的外部呈穹顶形隆起，从而能够增大按键4d2与机芯壳体41内部的按键开关431之间的距离，进而能够适当增大按键4d2触发按键开关431的按压行程，从而能够提高用户按压按键4d2的手感。
具体地，弹性支撑部4d112的底部固定于按键孔4122的侧壁面上，从而使得弹性支撑部4d112的顶部从按键孔4122外露，进而使得设置在弹性支撑部4d112的朝向机芯壳体41外部一端的支撑柱4d12完全外露于机芯壳体41的外部，并进而在机芯壳体41的外部与按键4d2固定在一起。
在一实施例中，机芯壳体41的外表面上设置有凹陷区4123，其中按键孔4122进一步位于凹陷区4123内。即凹陷区4121和凹陷区4123分别位于按键孔4122的两端，并由按键孔4122贯通。其中，凹陷区4121和凹陷区4123的形状、尺寸等可以根据实际需求而设置为相同或者不同。另外，凹陷区4121和凹陷区4123的数量可以相同，二者的数量可以根据按键4d2的数量而定，可以为一个或者多个，每个凹陷区4121和凹陷区4123内可以对应设置一个或者多个按键孔4122，此处不做具体限定。本实施方式中，该机芯壳体41对应的按键4d2数量为一个，且对应一个凹陷区4121和一个凹 陷区4123。
其中，支撑柱4d12由弹性支撑部4d112支撑至按键孔4122的朝向机芯壳体41外部一侧而位于凹陷区4123内，进一步地，按键4d2设置于支撑柱4d12的弹性支撑部4d112一侧，本实施方式中，通过设置弹性支撑部4d112以及支撑柱4d12的沿按键4d2的按压方向的高度，而使得按键4d2至少部分沉设于凹陷区4123内，以提高空间利用率，减少按键模块4d所占用的空间。
在一实施例中，按键4d2包括按键本体4d21以及设置于按键本体4d21一侧的环形凸缘4d22和环形凸缘4d23。其中，环形凸缘4d22和环形凸缘4d23具体可设置于按键本体4d21的按压面的对侧。
具体地，环形凸缘4d22位于按键本体4d21的中间区域，环形凸缘4d23位于按键本体4d21的外边缘，且环形凸缘4d22和环形凸缘4d23均朝向背离按键本体4d21的按压面的方向凸出形成，从而形成环形凸缘4d22围绕形成的柱状的容置空间4d24，以及由环形凸缘4d22和环形凸缘4d23共同围绕形成的环柱状的容置空间4d25。其中，环形凸缘4d22和环形凸缘4d23相对于按键本体4d21所凸出的高度可以相等或者不等。本实施方式中，环形凸缘4d22相对于按键本体4d21所凸出的高度大于环形凸缘4d23相对于按键本体4d21所凸出的高度。
其中，支撑柱4d12插置于环形凸缘4d22内部，即容置于容置空间4d24当中，具体地，支撑柱4d12可以通过粘接、注塑或者弹性抵接等方式与环形凸缘4d22固定在一起。
进一步地，环形凸缘4d23远离按键本体4d21的端面沉设于凹陷区4123内，并在弹性承座4d1处于自然状态时与凹陷区4123的底部间隔一定距离。
其中，凹陷区4123的底部是指凹陷区4123的朝向机芯壳体41内部的内壁面。具体地，在弹性承座4d1处于自然状态时，通过按压按键4d2的按压面，而使得弹性承座4d1的弹性支撑部4d112的顶部沿朝向机芯壳体41内的方向运动，并在环形凸缘4d23远离按键本体4d21的端面接触到凹陷区4123的底部之前，触发按键开关431。
在一实施例中，弹性承座4d1进一步包括用于接触按键开关431的接触头4d13，该接触头4d13可设置于承座本体4d11靠近机芯壳体41内部一侧，具体可设置于弹性支撑部4d112的顶部的朝向机芯壳体41内部的内壁面的中间区域，并相对于该内壁面 朝向机芯壳体41内部凸出设置。
在按压按键4d2时，弹性承座4d1的弹性支撑部4d112的顶部沿朝向机芯壳体41内的方向运动，从而带动接触头4d13朝向机芯壳体41内部的按键开关431运动，从而通过该接触头4d13触发按键开关431，从而实现相应的功能。通过这种方式，能够根据实际需求而减小按键4d2的按压行程。
在一个实施例中按键4d2的形状可以为圆角矩形，圆角矩形的按键4d2沿外侧壁的长度方向延伸。按键4d2包括两条对称轴，且相对于彼此垂直交叉的两个对称方向呈轴对称设置。
图9是本申请中扬声装置的一些实施例中表示距离D1、D2的示意图。如图9所示，在一个实施例中，按键4d2的顶部与外侧壁412的顶端位置之间的间距为第一间距D1。按键4d2的底部与外侧壁412的底端位置之间的间距为第二间距D2。第一间距D1与第二间距D2的比例可以不大于1。
具体的，当第一间距D1和第二间距D2之间的比例等于1时，可以认为按键4d2位于外侧壁412的中部位置；当第一间距D1和第二间距D2之间的比例小于1时，可以认为按键4d2位于外侧壁412的中部位置到顶端位置之间。
进一步的，第一间距D1与第二间距D2之间的比例可不大于0.95，从而使得按键4d2更靠近与外侧壁412的顶端位置，也即更靠近振动支点25，以进一步提高扬声器组件40的音量。其中，第一间距D1与第二间距D2之间的比例还可以为0.9、0.8、0.7、0.6、0.5等，具体可根据需求进行设置，此处不做限定。在一些实施例中，第一间距D1与第二间距D2之间的比例可以在0.01和0.95之间，或者0.02到0.8之间，或者0.1到0.7之间，或者0.2到0.6之间。
在一些实施例中，耳挂20与扬声器模块的连接部分可以具有中轴线。其中，可以包括一个外侧面。在一些实施例中，按键4d2的外侧面可以是用户佩戴骨传导耳机时，按键4d2的远离用户头部的侧面。在一些实施例中，中轴线的延长线r在按键的外侧面所在的平面上可具有投影。该投影与按键4d2的长轴方向之间的夹角θ可以小于10°，具体可以为9°、7°、5°、3°、1°等，此处不做具体限定。
其中，该延长线r在按键4d2的外侧面所在的平面上的投影与长轴方向之间的夹角的角度θ小于10°时，按键4d2的长轴方向不至过于偏离该延长线r的延长方向， 从而使得按键4d2在长轴方向上与该中轴线的延长线r的方向保持一致或者接近一致。
在一些实施例中，中轴线的延长线r在按键4d2的外侧面所在的平面上具有投影。按键4d2的外侧面的长轴方向和短轴方向具有交叉点，投影与交叉点之间的具有最短距离d。最短距离d小于按键4d2的外侧面的短轴方向上的尺寸s 2，从而使得按键4d2靠近于该耳挂的中轴线的延长线r。在一些实施例中，耳挂20的中轴线的延长线r在按键4d2的外侧面所在的平面上的投影可与长轴方向重合，以进一步提高扬声器组件40的音质。
在一些实施例中，按键4d2的长轴可以是沿按键4d2的顶部到按键4d2的底部的方向，也可以是耳挂20与机芯壳体41连接的方向上。按键4d2的短轴可以是沿与按键4d2的长轴垂直的，且经过顶部与底部之间的连线的中点的直线方向上。按键4d2沿长轴方向的尺寸为s 1，沿算周方向的尺寸为s 2。
在一些实施例中，第一周侧壁411a沿靠近振动支点12的方向具有底端位置、中部位置和顶端位置。
其中，第一周侧壁411a的底端位置可以为第一周侧壁411a与远离耳挂20的第二周侧壁411b的连接点。第一周侧壁411a的顶端位置可以为第一周侧壁411a与靠近耳挂20的第二周侧壁411b的连接点。中部位置可以为第一周侧壁411a的底端位置与顶端位置连线的中点。
在一些实施例中，按键模块4d可以位于第一周侧壁411a的中部位置(图中未示出)；或者按键模块4d位于第一周侧壁411a的中部位置到顶端位置之间(图中未示出)。并且，按键模块4d沿第一周侧壁411a的宽度方向居中设置在第一周侧壁411a上。
图10是本申请中扬声装置的一些实施例中表示距离l3、l4的示意图。在一些实施例中，按键模块4d的顶部与第一周侧壁411a的顶端位置之间沿按键模块4d长度方向的间距为第三距离l3。按键模块4d的底部与第一周侧壁411a的底端位置之间沿按键模块4d长度方向的间距为第四距离l4。第三距离l3与第四距离l4的比例可以不大于1。
进一步的，第三距离l3与第四距离l4之间的比例可不大于0.95。例如，第三距离l3与第四距离l4之间的比例还可以为0.9、0.8、0.7、0.6、0.5等，具体可根据需求 进行设置，此处不做限定。
在一些实施例中，按键孔4122也可以设置在第一周侧壁411a上(图中未示出)。例如，按键孔4122可以设置在第一周侧壁411a的中部位置到第一周侧壁411a的顶端位置之间(图中未示出)。按键孔4122的形状同样可以不受限制。且按键孔4122与按键4d2能够相互配合即可，使得按键4d2被配置为凸出于第一周侧壁411a的表面，方便用户进行操作即可。
在一些实施例中，扬声器组件40内还包括区别于按键模块4d之外的用于接收辅助信号而执行辅助功能的模块，例如麦克风模块、降噪模块等或其任意组合，具体可根据实际需求设置。
在一些实施例中，麦克风模块的中心与振动支点之间的距离可以不大于扬声器组件40除麦克风模块以外的部分的中心与振动支点之间的距离。从而在一定的驱动力下，增大扬声器组件40的振动加速度，进而提高扬声器组件40的音量。
在一些实施例中，麦克风模块的中心可以是质心M1(图中未示出)或者形心G1(图中未示出)，麦克风模块的质心M1或形心G1与耳挂顶端25(也即振动支点12)之间具有第一距离S1(图中未示出)。扬声器组件40除麦克风模块以外的部分的质心M2(图中未示出)或形心G2(图中未示出)与耳挂顶端25之间具有第二距离S2(图中未示出)。在一些实施例中，麦克风模块与扬声器组件40上除麦克风模块以外的部分的质量分布较为均匀，因此，可认为麦克风模块的质心M1与形心G1重合，扬声器组件40除麦克风模块以外的部分的质心M2与G2形心也重合。
在一些实施例中，麦克风模块在扬声器组件40内的质量分布与第一距离S1与第二距离S2之间的比例，以及麦克风模块的质量与扬声器组件40除麦克风模块以外的部分的质量比q有关。
具体地，在麦克风模块的质量一定的情况下，随着第一距离S1与第二距离S2之间的比例的增加，扬声器组件40在相同驱动力下的振动加速度减小，进而导致音量减小；而在第一距离S1与第二距离S2之间的比例一定的情况下，随着麦克风模块质量的增加，扬声器组件40在相同驱动力下的振动加速度减小，进而导致音量降低。因此，可通过调节第一距离S1与第二距离S2之间的比例以及麦克风模块的质量与扬声器组件40除麦克风模块以外的部分的质量比q，将由麦克风模块的设置而导致的音量降低 控制在一定范围之内。
在一些实施例中，第一距离S1与第二距离S2之间的比例可以不大于1。
具体地，在第一距离S1与第二距离S2之间的比例等于1时，麦克风模块的质心M1或形心G1与扬声器组件40除麦克风模块以外的部分的质心M2或形心G2重合，从而可认为该麦克风模块相对于扬声器组件40居中设置；在第一距离S1与第二距离S2之间的比例小于1时，麦克风模块的质心M1或形心G1相对于扬声器组件40除麦克风模块以外的部分的质心M2或形心G2更靠近耳挂顶端25的位置，从而可认为扬声器组件40靠近耳挂顶端25的近端4g。而且第一距离S1与第二距离S2之间的比例越小，则麦克风模块的质心M1或形心G1相对于扬声器组件40除麦克风模块以外的部分的质心M2或形心G2更靠近耳挂顶端25。
在一些实施例中，第一距离S1与第二距离S2之间的比例可以不大于0.90，从而使得麦克风模块更靠近于耳挂顶端25。其中，第一距离S1与第二距离S2之间的比例还可以为0.9、0.8、0.7、0.6、0.5等，具体可根据需求进行设置，此处不做限定。在一些实施例中，第一间距S1与第二间距S2之间的比例可以在0.1和0.950之间，或者0.2到0.8之间，或者0.3到0.7之间，或者0.4到0.6之间。
进一步地，在第一距离S1与第二距离S2之间的比例满足上述范围的情况下，麦克风模块的质量与扬声器组件40除麦克风模块以外的部分的质量比可不大于0.3，不大于0.2，不大于0.1，不大于0.06，不大于0.03，不大于0.01，或不大于0.005等，此处不做限定。
在一些实施例中，麦克风模块可以包括麦克风432和连接麦克风432与内部电路连接的电路，麦克风432可以设置与扬声器组件40一一对应设置，即一个扬声器组件40设置一个麦克风432，也可以只在一侧的扬声器组件40都设置有麦克风432。
在一些实施例中，麦克风432对应于麦克风组件4c。在一些实施例中机芯壳体41上设置有入声孔313a，从而使得外界声音所引起的防水膜本体4c11的振动穿过该入声孔313a从而进一步影响麦克风432。在一些实施例中，该扬声装置在机芯壳体41处还设置有一体成型于机芯壳体41的内表面的环形胶垫414，并设置于入声孔313a的外围，进而定义一与入声孔313a连通的容置空间415。
进一步地，麦克风组件4c还包括防水膜组件4c1和麦克风刚性支撑板4b。
在一些实施例中，防水膜组件4c1包括防水膜本体4c11以及环形胶垫4c13。该环形胶垫4c13设置于防水膜本体4c11朝向麦克风刚性支撑板4b的一侧。其中，麦克风刚性支撑板4b压持于环形胶垫4c13，从而使得防水膜组件4c1与麦克风刚性支撑板4b之间粘接固定于一起。
在一些实施例中，麦克风刚性支撑板4b设置于防水膜组件4c1与麦克风432之间，一方面对防水膜组件4c1进行压持，而使防水膜组件4c1紧密贴合于机芯壳体41的内表面；另一方面，麦克风刚性支撑板4b具有一定的强度，从而起到支撑麦克风432的作用。
在一些实施例中，麦克风刚性支撑板4b的材质可以为聚酰亚胺(PolyimiceFilm，PI)，或者其它能够起到强度支撑作用的材质，如聚碳酸酯、聚氯乙烯等。另外，麦克风刚性支撑板4b的厚度可以根据麦克风刚性支撑板4b的强度以及麦克风432所实际需求的强度进行设定，此处不做具体限定。其中，防水膜组件4c1设置于容置空间415内，并覆盖入声孔313a；麦克风刚性支撑板4b3a1设置于容置空间415内，并位于防水膜组件4c1的远离入声孔313a的一侧，以将防水膜组件4c1压持于机芯壳体41的内表面上。
通过上述方式，能够将防水膜组件4c1与入声孔313a外围的机芯壳体41的内表面紧密贴合，从而减少由入声孔313a进入的声音的散失，提高音量。
进一步地，由于防水膜本体4c11在振动时导致密封腔中气压发生变化，而该气压需要控制在适当的范围内，若过大或过小均为影响声音质量。本实施方式中，防水膜本体4c11和麦克风刚性支撑板4b之间的间距可以为0.1-0.2mm，具体可以为0.1mm、0.15mm、0.2mm等，从而使得防水膜本体4c11振动所导致的密封腔当中的气压变化在适当的范围之内，从而提高声音质量。
需要额外注意的是，扬声器组件40具有体积小、重量轻、效率高、灵敏度高及使用寿命长等特点，便于将扬声器组件40与穿戴式智能设备相结合，从而实现单一设备的多功能化，提高并优化用户体验。在一些实施例中，穿戴式智能设备包括但不限于智能耳机、智能眼镜、智能头箍、智能头盔、智能手表、智能手套、智能鞋、智能照相机、智能摄像机等等。在一些实施例中，扬声器组件40可进一步地与智能材料相结合，在用户的衣服、手套、帽子、鞋子等的制造材料中整合扬声装置。在一些实施例中，扬 声器组件40还可进一步地植入人体，与人体植入芯片或者外置处理器协同实现更加个性化的功能。
在一些实施例中，扬声装置可以通过多种不同的方式获取含有声音信息的信号，信号的获取可以是有线的或无线的，可以是实时或延时的。例如，扬声装置可以通过有线或者无线的方式接收含有声音信息的电信号。又例如，助听器中可以包括具有声音采集功能的组件，通过拾取环境中的声音，将声音的机械振动转换成电信号，通过放大器处理后获得满足特定要求的电信号。在一些实施例中，有线连接可以包括金属电缆、光学电缆或者金属和光学的混合电缆，例如，同轴电缆、通信电缆、软性电缆、螺旋电缆、非金属护皮电缆、金属护皮电缆、多芯电缆、双绞线电缆、带状电缆、屏蔽电缆、电信电缆、双股电缆、平行双芯导线、双绞线等一种或多种的组合。以上描述的例子仅作为方便说明之用，有线连接的媒介还可以是其它类型，例如，其它电信号或光信号等的传输载体。
无线连接可以包括无线电通信、自由空间光通信、声通讯、和电磁感应等。其中无线电通讯可以包括IEEE1002.11系列标准、IEEE1002.15系列标准(例如蓝牙技术和紫蜂技术等)、第一代移动通信技术、第二代移动通信技术(例如FDMA、TDMA、SDMA、CDMA、和SSMA等)、通用分组无线服务技术、第三代移动通信技术(例如CDMA2000、WCDMA、TD-SCDMA、和WiMAX等)、第四代移动通信技术(例如TD-lTE和FDD-lTE等)、卫星通信(例如GPS技术等)、近场通信(NFC)和其它运行在ISM频段(例如2.4GHz等)的技术；自由空间光通信可以包括可见光、红外线讯号等；声通讯可以包括声波、超声波讯号等；电磁感应可以包括近场通讯技术等。以上描述的例子仅作为方便说明之用，无线连接的媒介还可以是其它类型，例如，Z-wave技术、其它收费的民用无线电频段和军用无线电频段等。例如，作为本技术的一些应用场景，扬声装置可以通过蓝牙技术从其他设备获取含有声音信息的信号。
