具体实施例
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申请,而并非以任何方式限制本申请的范围。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,在描述本申请中关于声音传导相关技术时,将采用“扬声器装置” 或“扬声器装置扬声器”的描述。该描述仅仅为应用的一种形式,对于该领域的普通技术人员来说,“扬声器装置”或“扬声器”也可用其他同类词语代替,比如“发声装置”、“助听器”等。事实上,本申请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,在了解扬声器装置的基本原理后,可能在不背离这一原理的情况下,对实施扬声器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,在扬声器装置中加入环境声音拾取和处理功能,使该扬声器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)传送至扬声器部分。即扬声器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器部分将声音传递给使用者/佩戴者,从而实现扬声器的功能。作为举例,这里所说的算法可以包括噪声消除、自动增益控制、声反馈抑制、宽动态范围压缩、主动环境识别、主动抗噪、定向处理、耳鸣处理、多通道宽动态范围压缩、主动啸叫抑制、音量控制等一种或多种的组合。
请参阅图1-图2,图1是根据本申请一些实施例提供的扬声器装置的结构示意图;图2是根据本申请一些实施例提供的扬声器装置的扬声器组件的结构示意图。扬声器装置可以通过骨传导、气传导的方式将声音传递给人体的听觉系统,从而使用户产生听觉。在一些实施例中,扬声器装置可以包括支撑连接件10和设置于支撑连接件10上的至少一个扬声器组件40。在一些实施例中,支撑连接件10可以包括耳挂50。具体的,支撑连接件10可以包括两个耳挂50以及连接在两个耳挂之间的后挂30。佩戴时,两个耳挂50可以分别对应用户的左右耳,后挂30可以对应用户的头部后侧。耳挂可以用于与人体头部进行接触,耳挂50与人体头部的一个或多个接触点(即耳挂顶端25附近的一个或多个点)可以为扬声器组件40振动时的振动支点。
在一些实施例中,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50部分作为臂杆的往复摆动运动,该固定点可以被作为振动支点。其中,扬声器组件40摆动的幅度(即振动加速度)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可以包括耳机芯、用于容纳耳机芯的机芯壳体20、扬声器模块(图中未示出)以及至少一个按键模块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的除按键模块4d以外的部分,包括,例如耳机芯和机芯外壳。
进一步的,支撑连接件10中容纳控制电路(图中未示出)或电池(图中未示出),控制电路或电池驱动耳机芯振动以产生声音。
在一些实施例中,按键模块4d可以用于进行人机交互。例如: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,并且分别对应于左、右侧两个耳挂。用户可以使用左、右手分别操作按键模块4d,提高用户使用体验。
在一些实施例中,为了进一步提高用户的人机交互体验,可以将人机交互的功能分配到左、右两侧的按键模块4d,用户可以根据功能的不同操作对应的按键模块4d。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)。
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,上述人机交互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。从而增大扬声器组件40的振动加速度,进而提高扬声器组件40振动发出的音量。
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20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内的质量分布可以体现为第一距离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。
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,具体可根据需求进行设置,此处不做限定。
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。
在一些实施例中,按键模块4d的质心m1和形心g1可以不重合。具体的,由于按键模块4d的结构比较简单且规则,因此形心g1更容易计算出,所以选用形心g1作为参考点。扬声器模块的质心m2与形心g2也不重合,但由于扬声器模块所采用的材料不同(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)。因此,将扬声器模块的质心m2作为参考点。
在一个应用场景中,与上述实施例相对应的,按键模块4d的形心g1与耳挂顶端25之间可以具有第一距离l1,扬声器模块的质心m2与耳挂顶端25之间可以具有第二距离l2。按键模块4d在扬声器组件40内的质量分布可体现为第一距离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。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,扬声装置30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的设置而导致的音量降低控制在人耳所能够识别的范围之内。
在一个应用场景中,第一距离l1与第二距离l2之间的比例可不大于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30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30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可以更靠近于耳挂顶端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。
需要注意的是,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是根据本申请一些实施例提供的扬声器装置的扬声器组件的另一角度的结构示意图。在一些实施例中,扬声器模块可以包括用于产生声音的耳机芯以及容纳耳机芯的机芯壳体20。
在一些实施例中,机芯壳体20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。当用户佩戴扬声器装置时,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20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;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。
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20。耳机芯可以容纳于机芯壳体20的空腔内。
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可以围合成任意适用于用户头部佩戴的形状,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是本申请扬声器装置的一些实施例中表示距离h1的示意图;图5是本申请扬声器装置的一些实施例中表示距离h2的示意图;图6是本申请扬声器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,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。且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,且近端点和远端点分别位于轮廓的相对位置。在一些实施例中,近端点与振动支点之间的距离h1是最短的,称为顶端位置;远端点与振动支点之间的距离h2是最长的,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。
图7是根据本申请一些实施例提供的扬声器组件的局部结构截面图。如图7所示,按键模块4d进一步包括:弹性承座4d1、按键4d2。
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412的长度方向延伸。按键4d2包括两条对称轴(长轴和短轴),在相对于彼此垂直交叉的两个对称方向呈轴对称设置。
图8是本申请扬声器装置的一些实施例中表示距离D1、D2的示意图。如图8所示,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,在第一间距D1和第二间距D2之间的比例等于1时,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,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,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,耳挂50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扬声器装置时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50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50与机芯壳体20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 e,沿算周方向的尺寸为s 2
在一些实施例中,第一周侧壁411a沿靠近振动支点的方向具有底端位置、中部位置和顶端位置。
其中,底端位置可以为第一周侧壁411a与远离耳挂50的第二周侧壁411b的连接点。顶端位置可以为第一周侧壁411a与靠近耳挂50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可以位于第一周侧壁411b的中部位置到顶端位置之间(图中未示出)。并且按键模块沿4d第一周侧壁411a的宽度方向居中设置在第一周侧壁411a上。
图9是本申请扬声器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的顶端位置之间的间距为第三距离l3。按键模块4d的底部与第一周侧壁411的底端位置之间的间距为第四距离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,从而使得按键模块4d更靠近与第一周侧壁411a的顶端位置,也即更靠近振动支点,以进一步提高扬声器组件40的音量。其中,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。
其中,如前述披露内容所述,按键4d2的顶部与第一周侧壁411a的顶端位置之间存在第三间距D3,按键4d2的底部与第一周侧壁411a的底端位置之间存在第四间距D4。第三间距D3与第四间距D4的比例可以不大于1。
进一步的,第三间距D3与第四间距D4之间的比例可不大于0.95,从而使得按键4d2更靠近与第一周侧壁411a的顶端位置,也即更靠近振动支点,以进一步提高扬声器组件40的音量。其中,第三间距D3与第四间距D4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。
需要注意的是,以上对扬声器装置的描述仅仅是具体的示例,不应被视为是唯一可行的实施方案。显然,对于本领域的专业人员来说,在了解扬声器装置的基本原理后,可能在不背离这一原理的情况下,对实施扬声器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,但是这些修正和改变仍在以上描述的范围之内。例如,按键模块4d可以设置在只设置在左右两侧扬声器组件40中的其中一个内,也可以两个扬声器组件40都设置有按键模块4d。诸如此类的变形,均在本申请的保护范围之内。
在一些实施例中,扬声器装置还可以包括扬声机构,例如骨传导扬声机构、气传导扬声机构等。其中,骨传导是一种声音传导方式,即将声音转化为不同频率的机械振动,通过人的颅骨、骨迷路、内耳淋巴液传递、螺旋器、听神经、听觉中枢等来传递声波。在一些实施例中,扬声机构可以为MP3播放器、助听器等。
在一些实施例中,扬声器装置的扬声机构可以为单独的、可直接使用的播放器,或者还可以是插接在电子设备上使用的播放器。
需要知道的是,在不违背原理的情况下,以下描述的内容可以同样适用于气传导扬声器装置和骨传导扬声器装置。
图10是根据本申请一些实施例提供的扬声器装置的纵截面示意图。如图10所示,在一些实施例中,扬声器装置可以包括磁路组件210、线圈212、传振片214、连接件216、以及壳体220。进一步的,在一些实施例中,磁路组件210可以包括第一磁性元件202、第一导磁元件204和第二导磁元件206。在一些实施例中,机芯壳体20具有与壳体220相似或者相同的结构。

在一些实施例中,可以通过设计外壳面板222、外壳面板224和外壳侧面226的连接方式确保壳体220具有较大的刚度。在一些实施例中,外壳面板222、外壳面板224和外壳侧面226可以是一体成型。例如,外壳面板224和外壳侧面226可以是一体成型结构。又例如,外壳面板222和外壳侧面226可以通过胶水直接粘贴固定,或是通过卡接、焊接或螺纹连接的方式进行固定。胶水可以是粘性强、硬度较大的胶水。再例如,外壳面板222和外壳侧面226可以是一体成型结构,外壳面板224和外壳侧面226之间可以通过胶水直接粘贴固定,或是通过卡接、焊接或螺纹连接的方式进行固定。在一些实施例中,外壳面板222、外壳面板224和外壳侧面226都是独立的部件, 三者之间可以通过胶水、卡接、焊接或螺纹连接方式中的一种或任意几种的组合进行固定连接。例如,外壳面板222和外壳侧面226之间通过胶水连接,外壳面板224和外壳侧面226之间通过卡接、焊接或螺纹连接进行连接。或是外壳面板224和外壳侧面226之间通过胶水连接,外壳面板222和外壳侧面226之间通过卡接、焊接或螺纹连接进行连接。
在不同的应用场景中,本申请中所描述的扬声器装置的壳体可以通过不同的装配方式制成。例如,如本申请中其他地方的描述,扬声器装置的壳体可以是一体成型的方式,也可以是分体组合的方式,或者两者相结合的方式。在分体组合的方式中,不同分体之间可以采用胶水粘贴固定,或是通过卡接、焊接或螺纹连接的方式进行固定。具体地,为了更好地理解本申请中扬声器装置的壳体的装配方式,图11-13描述了几种扬声器装置的壳体的装配方式的示例。

需要说明的是,上述实施例中的壳体、机芯壳体和外壳可以是同一结构,都可以用于指代容纳磁路组件的结构,面板和外壳面板也可以是同一结构,都可以用于指代于人体接触传送声音的结构。而驱动装置101则相当于前述实施例中的耳机芯。
在一些实施例中,驱动装置101通过传动组件303将振动信号传送至面板301和/或外壳302,从而通过面板301或外壳302与人体皮肤的接触,将声音传送至人体。在一些实施例中,扬声器的面板301和/或外壳302可以在耳屏处与人体皮肤接触,从而将声音传递至人体。在一些实施例中,面板301和/或外壳302也可以在耳廓后侧与人体皮肤接触。

进一步的,面板301上具有与使用者身体,如人体皮肤,接触或抵靠的区域。应当理解为,当面板301上覆盖有其他材料(如硅胶等软性材料)以增强用户佩戴舒适感时,面板301与使用者身体的关系则不为直接接触,而是相互抵靠。在一些实施例中,当扬声器佩戴在使用者身体上后,面板301的全部区域与使用者身体接触或抵靠。在一些实施例中,当扬声器佩戴在使用者身体上后,面板301的部分区域与使用者身体接触或抵靠。在一些实施例中,面板301上用于与使用者身体接触或抵靠的区域可以占整个面板301面积的50%以上,更优选的,可以占面板面积的60%以上。一般来说,面板301上与使用者身体接触或抵靠的区域可以是平面或者曲面。

为曲面上任意一点的法线,ds为面元。
更进一步地,曲面为接近平面的准平面,即曲面上至少50%区域内任意一点的法线与其平均法线的夹角小于设定阈值的面。在一些实施例中,设定阈值小于10°;在一些实施例中,设定阈值可以进一步小于5°。
在一些实施例中,驱动力所在直线B与面板301上用于与使用者身体接触或抵靠的区域的法线A’具有夹角θ。夹角θ的数值范围可以为0<θ<180°,进一步其数值范围可以为0<θ<180° 且不等于90°。在一些实施例中,设定直线B具有指向扬声器外的正方向,设定面板301的法线A(或者面板301与人体皮肤接触面的法线A’)也具有指向扬声器外的正方向,则直线A或A’与直线B在其正方向上形成的夹角θ为锐角,即0<θ<90°。
图16是根据本申请一些实施例提供的一种夹角方向的示意图。如图16所示,在一些实施例中,驱动装置101产生的驱动力在XOY平面坐标系的第一象限和/或第三象限内具有分量。其中,XOY平面坐标系为一个参考坐标系,其原点O位于扬声器佩戴在人体上后,面板和/或外壳与人体的接触面上,X轴与人体冠状轴平行,Y轴与人体矢状轴平行,且X轴正方向朝向人体外侧,Y轴正方向朝向人体前方。象限应当被理解为平面直角坐标系中的横轴(如X轴)和纵轴(如Y轴)所划分的四个区域,每一个区域叫做一个象限。象限以原点为中心,X、Y轴为分界线。右上的(X轴的正半轴与Y轴的正半轴围成的区域)称为第一象限,左上的(X轴的负半轴与Y轴的正半轴围成的区域)称为第二象限,左下的(X轴的负半轴与Y轴的负半轴围成的区域)称为第三象限,右下的(X轴的正半轴与Y轴的负半轴围成的区域)称为第四象限。其中,坐标轴上的点不属于任何象限。应当理解为,本实施例驱动力可以直接位于XOY平面坐标系的第一象限和/或第三象限中,或者驱动力朝向其他方向,但是在XOY平面坐标系的第一象限和/或第三象限中的投影或分量不为0,以及在Z轴方向的投影或分量可以为0或不为0。其中,Z轴垂直于XOY平面,且经过原点O。在一些实施例中,驱动力所在直线与面板上与使用者身体接触或抵靠的区域的法线之间的最小夹角θ可以为任意锐角,例如夹角θ的范围优选为5°~80°;更优选为15°~70°;再优选为25°~60°;再优选为25°~50°;再优选为28°~50°;再优选为30°~39°;再优选为31°~38°;更优选为32°~37°;更优先选为33°~36°;更优先选为33°~35.8°;更优先选为33.5°~35°。具体的,夹角θ可以是26°、27°、28°、29°、30°、31°、32°、33°、34°、34.2°、35°、35.8°、36°、37°或38°等,误差控制在0.2度以内。需要说明的是,上述对驱动力方向的说明不应理解为本申请中驱动力的限制,在其他实施例中,驱动力还可以在XOY平面坐标系中的第二、四象限具有分量,甚至驱动力还可以位于Y轴上等等。
图17是根据本申请一些实施例提供的扬声器装置作用于人体皮肤、骨骼的结构示意图。如图17所示,扬声器装置包括驱动装置101(在其他实施例中也可称为换能装置),传动组件303,面板301,以及外壳302。
在一些实施例中,驱动力所在的直线与驱动装置101振动所在的直线共线或平行。例如,在动圈原理的驱动装置101中,驱动力的方向可以与线圈和/或磁路组件的振动方向相同或相反。面板301可以为平面,也可以为曲面,或者面板301上具有若干凸起或凹槽。在一些实施例中,当扬声器装置佩戴在使用者身体上后,面板301上与使用者身体接触或抵靠的区域的法线与驱动力所在的直线不平行。一般来说,面板301上与使用者身体接触或抵靠的区域较为平坦,具体可以是平面,或者曲度变化不大的准平面。当面板301上用于与使用者身体接触或抵靠的区域为平面时,其上任意一点的法线均可以作为区域的法线。当面板301上用于与使用者身体接触面板为非平面时,区域的法线可以为其平均法线,此时,上述面板301的法线A与面板301与人体皮肤接触面的法线A’ 可以为平行或重合。关于平均法线的详细定义可以参见图15中的相关描述,在此不再赘述。在其他一些实施例中,当面板上用于与使用者身体接触面板为非平面时,区域的法线还可以如下确定,选定面板301与人体皮肤接触时的一个区域中的某一点,确定面板301在该点处的切平面,再确定过该点且与切平面垂直的直线,将该直线作为面板的法线。当面板301上用于与人体皮肤接触面板为非平面时,所选的点不同,面板在该点出的切平面不同,所确定的法线也会有所差异,此时的法线A’与面板的法线A是不平行的。根据本申请一个具体实施例,驱动力所在直线(或驱动装置101振动所在直线)与区域的法线具有夹角θ,夹角0<θ<180°。在一些实施例中,当指定驱动力所在直线具有经面板(或者面板和/或外壳与人体皮肤接触面)指向扬声器装置外的正方向,指定面板(或者面板301和/或外壳302与人体皮肤接触面)法线具有指向扬声器装置外的正方向,这两条直线在正方向上形成的夹角为锐角。如图17所示,在一些实施例中,线圈304与磁路组件307均为环状结构。在一些实施例中,线圈304与磁路组件307具有相互平行的轴线,线圈304或磁路组件307的轴线与线圈304径向平面和/或磁路组件307径向平面垂直。在又一些实施例中,线圈304与磁路组件307具有相同的中心轴线,线圈304的中心轴线与线圈304径向平面垂直,且经过线圈304的几何中心,磁路组件307的中心轴线与磁路组件307径向平面垂直,且经过磁路组件307的几何中心。线圈304或磁路组件307的轴线与面板301的法线具有前述夹角θ。
在一些实施例中,上述实施例中的磁路组件可以是同一结构,都可以用于指代提供磁场的结构,上述实施例中的线圈也可以是同一结构,都可以用于指代能够接收外接电信号,将电信号在磁场的作用下转化为机械振动信号的元件。
仅仅作为示例,下面结合图17,阐述驱动力F与皮肤变形S之间的关系。当驱动装置101产生的驱动力所在直线与面板301法线平行时(也就是夹角θ为零),驱动力与皮肤总形变的关系为:
F =S ×E×A/h                           (2)
其中F 为驱动力大小,S 为皮肤在垂直皮肤方向的总形变,E为皮肤的弹性模量,A为面板301与皮肤的接触面积,h为皮肤的总厚度(也即面板与骨骼之间的距离)。
当驱动装置101的驱动力所在直线与面板上与使用者身体接触或抵靠的区域的法线垂直时(也就是夹角θ为90度),垂直方向的驱动力与皮肤总形变的关系可以如公式所示:
F //=S //×G×A/h                           (3)
其中F //为驱动力大小,S //为皮肤在平行皮肤方向的总形变,G为皮肤的剪切模量,A为面板301与皮肤的接触面积,h为皮肤的总厚度(也即面板与骨骼之间的距离)。
剪切模量G与弹性模量E之间的关系为:
G=E/2(1+γ)                              (4)
其中γ为皮肤的泊松比0<γ<0.5,因而剪切模量G小于弹性模量E,对应在相同的驱动力下皮肤的总形变S //>S 。通常,皮肤的泊松比接近0.4。
当驱动装置101产生驱动力所在直线与面板301与使用者身体接触的区域的法线不平行时,水平方向驱动力与垂直方向的驱动力分别表示为以下的公式(5)和公式(6):
F =F×cos(θ)                             (5)
F //=F×sin(θ)                             (6)
其中,驱动力F与皮肤变形S之间的关系可由以下公式(5)表示:
Figure PCTCN2019102382-appb-000004
当皮肤的泊松比为0.4时,夹角θ与皮肤总形变之间的关系的详细描述可以在图18中找到。
图18是根据本申请一些实施例提供的扬声器装置的夹角-相对位移关系图。如图18所示,夹角θ与皮肤总形变之间的关系为夹角θ越大,相对位移越大,则皮肤总形变S越大。皮肤在垂直皮肤方向形变S 随着夹角θ的变大,相对位移变小,皮肤在垂直皮肤方向形变S 变小;并且在夹角θ接近90度时,皮肤在垂直皮肤方向形变S 逐渐趋向于0。
在一些实施例中,扬声器装置在低频部分的音量与皮肤总变形S正相关。S越大,低频的音量越大。扬声器装置在高频部分的音量与皮肤在垂直皮肤方向形变S 正相关。S 越大,低频的音量越大。
进一步的,当皮肤的泊松比为0.4时,夹角θ与皮肤总形变S,皮肤在垂直皮肤方向形变S 之间的关系的详细描述可以在图18中找到。如图8所示,夹角θ与皮肤总形变S之间的关系为夹角θ越大,皮肤总形变S越大,对应扬声器装置的低频部分音量越大。如图18所示,夹角θ与皮肤在垂直皮肤方向形变S⊥之间的关系为夹角θ越大,皮肤在垂直皮肤方向形变S⊥越小,对应扬声器装置的高频部分音量越小。
通过方程(7)以及图18的曲线可以看出,随着夹角θ的增大,皮肤总形变S增大的速度与皮肤在垂直皮肤方向形变S 减小的速度不同。皮肤总形变S增大的速度先变快后变慢,皮肤在垂直皮肤方向形变S 减小的速度越来越快。为平衡耳机低频与高频的音量,夹角θ要在一个合适的大小。例如θ的范围为5°~80°,或者为15°~70°,或者为25°~50°,或者为25°~35°,或者为25°~30°等等。
图19是根据本申请一些实施例提供的不同夹角θ时扬声器装置的频率响应曲线低频段部分的示意图。如图19所示,面板301与皮肤接触,将振动传递到皮肤。在这个过程中,皮肤也会影响扬声器装置的振动,从而影响到扬声器装置的频率响应曲线。从上面的分析中,我们发现夹角度越大,相同的驱动力下皮肤的总形变越大,而对应扬声器装置来说,相当于皮肤相对其面板301部分的弹性减小。进一步地可以理解为,在驱动装置101的驱动力所在直线与面板301上与使用者身体接触或抵靠区域的法线形成一定夹角θ时,尤其是当夹角θ加大时,可以将频率响应曲线中的低频区域的谐振峰调节至更低频的区域,使低频下潜更深,低频增多。相对于其他提高声音中低频成分的技术手段,如在扬声器装置中增设传振片,设置夹角能够在提高低频能量的同时有效抑制振动感的增加,进而使振动感相对减少,使得扬声器装置低频灵敏度显著提高,提高音质和人体的体验感。应当注意的是,在一些实施例中,低频增多,振动感少可以表现为夹角θ在(0,90°)范围内增大时,振动或声音信号中的低频范围的能量增加了,同时振动感也增加了,但是低频范围的能量 增加的程度比振动感增加的程度更大,因此,在相对效果上,振动感相对减小了。从图19可以看出,夹角较大时,低频区的谐振峰出现在更低频段处,可以变相地延长频率曲率平坦的部分,从而提高耳机的音质。
需要注意的是,以上对扬声器装置的描述仅仅是具体的示例,不应该被视为是唯一可行的实施方案。显然,对于本领域的专业人员来说,在了解扬声器装置的基本原理后,可能在不背离这一原理的情况下,对实施扬声器装置的具体方式和步骤进行形式和细节上的各种修正和改变,但是这些修正和改变仍在以上描述的范围之内。例如,驱动力所在直线与面板上与使用者身体接触或抵靠的区域的法线之间的最小夹角θ可以为任意锐角,此处的锐角不仅仅局限于上述的5°~80°,在一些实施例中,夹角θ可以小于5°,例如1°、2°、3°、4°等。在另一些实施例中,夹角θ可以大于80°且小于90°,例如81°、82°、85°等。在一些实施例中,夹角θ的具体数值可以不为整数(例如81.3°、81.38°)。诸如此类的变形,均在本申请的保护范围之内。
图20是根据本申请一些实施例提供的扬声器装置的纵截面示意图。需要知道的是,在不违背原理的情况下,以下描述的内容可以同样适用于气传导扬声装置和骨传导扬声装置。
如图20所示,在一些实施例中,扬声器装置可以包括第一磁性元件202、第一导磁元件204、第二导磁元件206、第一振动板208、音圈110、第二振动板112以及振动面板114。其中,骨传导扬声器中耳机芯的部分元件可以组成磁路组件。在一些实施例中,磁路组件可以包括第一磁性元件102、第一导磁元件104、第二导磁元件106。磁路组件可以产生第一全磁场(也可被称为“磁路组件的总磁场”或“第一磁场”)。
在本申请中描述的磁性元件都可以用于指代产生磁场的元件,例如磁铁等。磁性元件可以具有磁化方向,磁化方向是指在磁性元件内部的磁场方向。在一些实施例中,第一磁性元件202可以包括一个或多个磁铁,第一磁性元件可以产生第二磁场。在一些实施例中,磁铁可以包括金属合金磁铁,铁氧体等。其中,金属合金磁铁可以包括钕铁硼、钐钴、铝镍钴、铁铬钴、铝铁硼、铁碳铝,或类似的,或其中多种的组合。铁氧体可以包括钡铁氧体,钢铁氧体,美锰铁氧体,锂锰铁氧体,或类似的,或其中多种组合。
在一些实施例中,第一导磁元件204的下表面可以连接第一磁性元件202的上表面。第二导磁元件206可以连接第一磁性元件202。需要注意的是,这里所说的导磁体也可以称为磁场集中器或铁芯。导磁体可以调整磁场(例如,第一磁性元件202产生的第二磁场)的分布。导磁体可以包括由软磁材料加工而成的元件。在一些实施例中,软磁材料可以包括金属材料、金属合金、金属氧化物材料、非晶金属材料等,例如铁、铁硅系合金、铁铝系合金、镍铁系合金、铁钴系合金、低碳钢、硅钢片、矽钢片、铁氧体等。在一些实施例中,可以通过铸造、塑性加工、切削加工、粉末冶金等一种或多种组合的方法加工导磁体。铸造可以包括砂型铸造、熔模铸造、压力铸造、离心铸造等;塑性加工可以包括轧制、铸造、锻造、冲压、挤压、拔制等一种或多种组合;切削加工可以包括车削、铣削、刨削、磨削等。在一些实施例中,导磁体的加工方法可以包括3D打印、数控机床等。第一导磁元件204、第二导磁元件206与第一磁性元件202之间的连接方式可以包括粘接、卡 接、焊接、铆接、螺栓连接等一种或多种组合。在一些实施例中,第一磁性元件202、第一导磁元件204和第二导磁元件206可以设置为轴对称结构。轴对称结构可以是环状结构、柱状结构或是其它具有轴对称结构。
在一些实施例中,第一磁性元件202与第二导磁元件206之间可以形成磁间隙。音圈110可以设置于磁间隙中。音圈110可以与第一振动板208连接。第一振动板208可以连接第二振动板112,第二振动板112可以连接振动面板114。当音圈110内通入电流后,音圈110位于在第一磁性元件202、第一导磁元件204和第二导磁元件206形成的磁场,会受到安培力作用,安培力驱动音圈110振动,音圈110的振动会带动第一振动板208、第二振动板112和振动面板114的振动。振动面板114将振动通过组织与骨骼传递到听觉神经,从而使人听到声音。振动面板114可以直接与人体皮肤接触,或可以通过由特定材料组成的振动传递层与皮肤接触。
在一些实施例中,对于具有单一磁性元件的扬声器装置,通过音圈110处的磁感线并不均匀,呈发散状。同时磁路中可能会形成漏磁,即较多的磁感线泄漏至磁间隙以外,未能穿过音圈110,从而使得音圈110位置处的磁感应强度(或磁场强度)下降,影响扬声器的灵敏度。因此,扬声器可以进一步包括至少一个第二磁性元件和/至少一个第三导磁元件(图中未示)。至少一个第二磁性元件和/至少一个第三导磁元件可以抑制磁感线的泄露,约束穿过音圈110的磁感线形态,使得较多的磁感线尽量水平密集地穿过音圈110,增强音圈110位置处的磁感应强度(或磁场强度),从而提高扬声器的灵敏度,进而提高扬声器的机械转化效率(即,将输入扬声器100的电能转化为音圈110振动的机械能的效率)。

在一些实施例中,第一磁性元件202和/或第一导磁元件204与第二磁性元件208的内环之间形成磁间隙。音圈238可以设置于磁间隙中。在一些实施例中,第二磁性元件208的音圈238相对于第二导磁元件206的底板的高度相等。
在一些实施例中,第一磁性元件202、第一导磁元件204、第二导磁元件206以及第二磁性元件208可以形成磁回路。在一些实施例中,磁路组件2100可以产生第一全磁场(也可被称为“磁路组件的总磁场”或“第一磁场”),第一磁性元件202可以产生第二磁场。第一全磁场由磁路组件2100中的所有组分(例如,第一磁性元件202,第一导磁元件204、第二导磁元件206以及第二磁性元件208)产生的磁场共同形成。
在一些实施例中,第一全磁场在磁间隙内的磁场强度(也可以被称为磁感应强度或者磁通量密度)大于第二磁场在磁间隙内的磁场强度。在一些实施例中,第二磁性元件208可以产生第三磁场,第三磁场可以提高第一全磁场在磁间隙处的磁场强度。这里所说的第三磁场提高第一全磁场的磁场强度指的是,在有第三磁场存在(即,存在第二磁性元件208)时第一全磁场在磁间隙的磁场强度大于没有第三磁场存在(即,不存在第二磁性元件208)时第一全磁场的。在本说明书中的其他实施例中,除非特别说明,磁路组件表示包含所有磁性元件和导磁元件的结构,第一全磁场表示由磁路组件整体产生的磁场,第二磁场、第三磁场、……、第N磁场分别表示由相应的磁性元件所产生的磁场。在不同的实施例中,产生第二磁场(或者第三磁场、……、第N磁场)的磁性元件可以是相同的,也可以不同。

在一些实施例中,在第二磁性元件208的位置,第一全磁场的方向与第二磁性元件208的磁化方向之间的夹角不高于90度。在一些实施例中,在第二磁性元件208的位置处,第一磁性元件202产生的磁场的方向与第二磁性元件208的磁化方向之间的夹角可以是0度、10度、20度等小于或等于90度的夹角。进一步的,与单一磁性元件的磁路组件相比,第二磁性元件208可以提高磁路组件2100中磁间隙内总磁通量,进而增加磁间隙中的磁感应强度。并且,在第二磁性元件208的作用下,原本发散的磁感线会向磁间隙所在位置收敛,进一步增加磁间隙中的磁感应强度。
图22是根据本申请一些实施例提供的磁路组件的纵截面示意图。如图22所示,与磁路组件2100不同的是,磁路组件2600可以进一步包括至少一个导电元件(例如,第一导电元件248、第二导电元件250及第三导电元件252)。
在一些实施例中,导电元件可以包括金属材料、金属合金材料、无机非金属材料或其它导电材料。金属材料可以包括金、银、铜、铝等;金属合金材料看可以包括铁基合金、铝基合金材料、铜基合金、锌基合金等;无机非金属材料可以包括石墨等。导电元件可以是片状、环状、网状等。第一导电元件248可以设置于第一导磁元件204的上表面。第二导电元件250可以连接第一磁性元件202以及第二导磁元件206。第三导电元件252可以连接第一磁性元件202的侧壁。在一些实施例中,第一导磁元件204可以凸出于第一磁性元件202形成第一凹部,第三导电元件252设置于第一凹部。在一些实施例中,第一导电元件248、第二导电元件250以及第三导电元件252可以包括相同或不同的导电材料。第一导电元件248、第二导电元件250以及第三导电元件252可以通过本申请中描述的任意一种或多种连接方式分别连接第一导磁元件204、第二导磁元件206和/或第一磁性元件202。
在一些实施例中,第一磁性元件202、第一导磁元件204与第二磁性元件208的内环之间形成磁间隙。音圈238可以设置于磁间隙中。第一磁性元件202、第一导磁元件204、第二导磁元件206以及第二磁性元件208可以形成磁回路。在一些实施例中,导电元件可以降低音圈238的感抗。例如,若音圈238通入第一交变电流时,音圈238附近会产生第一交变感应磁场。第一交变感应磁场在磁回路中磁场的作用下,会使音圈238产生感抗,阻碍音圈238的运动。当在音圈238附近设置导电元件(例如,第一导电元件248、第二导电元件250以及第三导电元件252),在第一交变感应磁场作用下,导电元件可以感生出第二交变电流。导电元件内的第三交变电流可以在其附近产生第二交变感应磁场,第二交变感应磁场与第一交变感应磁场方向相反,可以减弱第一交变感应磁场,从而减小音圈238的感抗,增大音圈中的电流,提高扬声器装置的灵敏度。
图23是根据本申请一些实施例提供的扬声器装置的纵截面示意图。如图23所示,与磁路组件2500不同的是,磁路组件2700可以进一步包括第三磁性元件510、第四磁性元件512、第五磁性元件514、第三导磁元件516、第六磁性元件524以及第七磁性元件526。第三磁性元件510、第四磁性元件512、第五磁性元件514、第三导磁元件516和/或第六磁性元件524以及第七磁性元件526可以设置为共轴的环形柱体。

在一些实施例中,在第七磁性元件526处,磁路组件2700产生的磁场的方向与第七磁性元件526的磁化方向之间的夹角不高于90度。在一些实施例中,在第七磁性元件526的位置处,第一磁性元件202产生的磁场的方向与第七磁性元件526的磁化方向之间的夹角可以是0度、10度、20度等小于或等于90度的夹角。
在磁路组件2700中,第三导磁元件516可以将磁路组件2700产生的磁路封闭,使得较多的磁感线集中于磁间隙内,从而达到抑制漏磁、增加磁间隙处的磁感应强度、及提高扬声器的灵敏 度的功效。
图24是根据本申请一些实施例提供的扬声器装置的纵截面示意图。如图24所示,磁路组件3100可以包括第一磁性元件602、第一导磁元件604、第一全磁场改变元件606以及第二磁性元件608。

图26是根据本申请一些实施例提供的磁路组件的纵截面示意图。如图26所示,磁路组件4100可以包括第一磁性元件402、第一导磁元件404、第二导磁元件406以及第二磁性元件408。
需要说明的是,上述实施例中的磁路组件都可以用于指代提供磁场的结构。上述实施例的磁性元件都可以用于指代储能、能量转换及电气隔离的元件。上述实施例的导磁元件都可以用于指代形成磁场回路的元件。
在一些实施例中,第一磁性元件402和/或第二磁性元件408可以包括本申请中描述的任意一种或几种磁铁。在一些实施例中,第一磁性元件402可以包括第一磁铁,第二磁性元件408可以包括第二磁铁,第一磁铁与第二磁铁可以相同或不同。第一导磁元件404和/或第二导磁元件406可以包括本申请中描述的任意一种或几种导磁材料。第一导磁元件404和/或第二导磁元件406的加工 方法可以包括本申请中描述的任意一种或几种加工方式。在一些实施例中,第一磁性元件402、第一导磁元件404和/或第二磁性元件408可以设置为轴对称结构。例如,第一磁性元件402、第一导磁元件404和/或第二磁性元件408可以是圆柱体。在一些实施例中,第一磁性元件402、第一导磁元件404和/或第二磁性元件408可以是共轴的圆柱体,含有相同或者不同的直径。第一磁性元件402的厚度可以大于或等于第二磁性元件408的厚度。在一些实施例中,第二导磁元件406可以是凹槽型结构。在一些实施例中,凹槽型结构可以包含U型的剖面,凹槽型的第二导磁元件406可以包括底板和侧壁。在一些实施例中,底板和侧壁可以是一体成型的,例如,侧壁可以由底板在垂直于底板的方向进行延伸形成。在一些实施例中,底板可以通过本申请中描述的任意一种或几种连接方式连接侧壁。第二磁性元件408可以设定为环状或片状。关于第二磁性元件408的形状可参考说明书中其他地方的描述。在一些实施例中,第二磁性元件408可以与第一磁性元件402和/或第一导磁元件404共轴。
进一步的,第一磁性元件402的上表面可以连接第一导磁元件404的下表面。第一磁性元件402的下表面可以连接第二导磁元件406的底板。第二磁性元件408的下表面连接第一导磁元件404的上表面。第一磁性元件402、第一导磁元件404、第二导磁元件406和/或第二磁性元件408之间的连接方式可以包括粘接、卡接、焊接、铆接、螺栓连接等一种或多种组合。
在进一步的,第一磁性元件402、第一导磁元件404和/或第二磁性元件408与第二导磁元件406的侧壁之间形成磁间隙。音圈可以设置于磁间隙中。在一些实施例中,第一磁性元件402、第一导磁元件404、第二导磁元件406以及第二磁性元件408可以形成磁回路。在一些实施例中,磁路组件4100可以产生第一全磁场,第一磁性元件402可以产生第二磁场。第一全磁场由磁路组件4100中的所有组分(例如,第一磁性元件402,第一导磁元件404、第二导磁元件406以及第二磁性元件408)产生的磁场共同形成。第一全磁场在磁间隙内的磁场强度(也可以被称为磁感应强度或者磁通量密度)大于第二磁场在磁间隙内的磁场强度。在一些实施例中,第二磁性元件408可以产生第三磁场,第三磁场可以提高第二磁场在磁间隙处的磁场强度。
在一些实施例中,第二磁性元件408的磁化方向与第一磁性元件402的磁化方向之间的夹角在90度与180度之间。在一些实施例中,第二磁性元件408的磁化方向与第一磁性元件402的磁化方向之间的夹角在150度与180度之间。在一些实施例中,第二磁性元件408的磁化方向与第一磁性元件402的磁化方向相反(如图所示,a方向与b方向)。
与单一磁性元件的磁路组件相比,磁路组件4100增加了第二磁性元件408。第二磁性元件408磁化方向与第一磁性元件402磁化方向相反,可以抑制第一磁性元件402在磁化方向上的漏磁,从而使第一磁性元件402产生的磁场可以较多地被压缩到磁间隙中,因而提高磁间隙内的磁感应强度。
以上对扬声器装置的描述仅仅是具体的示例,不应被视为是唯一可行的实施方案。显然,对于本领域的专业人员来说,在了解扬声器装置的基本原理后,可能在不背离这一原理的情况下,对实施扬声器装置的具体方式形式和细节上的各种修正和改变,但是这些修正和改变仍在以上描述 的范围之内。例如磁路组件中的磁性元件不限于上述的第一磁性元件、第二磁性元件、第三磁性元件、第四磁性元元件、第五磁性元件、第六磁性元件、第七磁性元件,还可以增加或减少磁性元件的数量。诸如此类的变形,均在本申请的保护范围之内。
在一些实施例中,以上描述的扬声器装置可以通过气传导的方式将声音传递给用户。当采用气传导的方式传递声音时,扬声器装置可以包括一个或多个声源。声源可以位于用户头部的特定位置,例如,头顶、额头、脸颊、鬓角、耳廓、耳廓背面等,而不用堵塞或者覆盖耳道。出于描述的目的,图27是显示一种通过气传导的方式传递声音的示意图。
如图27所示,声源3010和声源3020可以产生相位相反的声波(图中以“+”和“-”表示相位相反)。为简单起见,这里所说的声源指的是扬声器装置上输出声音的出声孔。例如,声源3010和声源3020可以是分别位于扬声器装置上特定位置(例如,机芯壳体20,或者支撑连接件10)的两个出声孔。
在一些实施例中,声源3010和声源3020可以由同一个振动装置3001产生。振动装置3001包括振膜(未显示在图中)。当振膜受到电信号驱动而振动时,振膜正面驱动空气振动,通过导声通道3012在出声孔处形成声源3010,振膜背面驱动空气振动,通过导声通道3022在出声孔处形成声源3020。所述导声通道指的是振膜到对应出声孔的声音传播路径。在一些实施例中,所述导声通道是由扬声器上特定结构(例如,机芯壳体20,或者支撑连接件10)围成的路径。需要知道的是,在一些可替代的实施例中,声源3010和声源3020还可以由不同的振动装置,分别通过不同的振膜振动产生。
由声源3010和声源3020产生的声音中,一部分传递给用户耳朵形成用户听到的声音,另一部分传递到环境中形成漏音。考虑到声源3010和声源3020距离用户耳朵的位置较近,为了描述方便,传递到用户耳朵的声音可以称为近场声音,传递到环境中的漏音可以称为远场声音。在一些实施例中,扬声器装置产生的不同频率的近场/远场声音与声源3010和声源3020之间的间距有关。一般说来,扬声器装置产生的近场声音会随着两个声源之间间距的增大而增大,而产生的远场声音(漏音)会随着频率的增加而增大。
针对不同频率的声音,可以分别设计声源3010和声源3020之间的间距,使得扬声器装置产生的低频近场声音(例如,频率小于800Hz的声音)尽可能大,且高频远场声音(例如,频率大于2000Hz的声音)尽可能小。为了达到以上目的,所述扬声器装置中可以包括两组或两组以上的双声源,每组双声源包含类似于声源3010和声源3020的两个声源,并分别产生特定频率的声音。具体地,第一组双声源可以用于产生低频声音,第二组双声源可以用产生高频声音。为了获得较大的低频近场声音,第一组双声源中两个声源之间的距离可以设置为较大的值。并且由于低频信号的波长较长,双声源之间较大的距离不会在远场形成过大的相位差,因而也不会在远场中形成过多的漏音。为了使得高频远场声音较小,第二组双声源中两个声源之间的距离可以设置为较小的值。由于高频信号的波长较短,双声源之间较小的距离可以避免在远场形成大的相位差,因而可以避免形成大的漏音。第二组双声源之间的距离小于所述第一组双声源之间的距离。
本申请实施例可能带来的有益效果包括但不限于:(1)优化了扬声器装置上按键模块的位置,提高了振动效率。(2)提高了扬声器装置的声音传递效率,提高了音量。(3)通过调整面板的法线A或面板与人体皮肤接触面的法线A’与装置驱动力所在直线B之间的夹角θ可以改善扬声器装置的音质。(4)通过在磁路组件中增设磁性元件、导磁元件和导电元件,可以提高扬声器装置的灵敏度。需要说明的是,不同实施例可能产生的有益效果不同,在不同的实施例里,可能产生的有益效果可以是以上任意一种或几种的组合,也可以是其他任何可能获得的有益效果。
上文已对基本概念做了描述,显然,对于本领域技术人员来说,上述发明披露仅仅作为示例,而并不构成对本申请的限定。虽然此处并没有明确说明,本领域技术人员可能会对本申请进行各种修改、改进和修正。该类修改、改进和修正在本申请中被建议,所以该类修改、改进、修正仍属于本申请示范实施例的精神和范围。
同时,本申请使用了特定词语来描述本申请的实施例。如“一个实施例”、“一实施例”和/或“一些实施例”意指与本申请至少一个实施例相关的某一特征、结构或特点。因此,应强调并注意的是,本说明书中在不同位置两次或多次提及的“一实施例”或“一个实施例”或“一替代性实施例”并不一定是指同一实施例。此外,本申请的一个或多个实施例中的某些特征、结构或特点可以进行适当的组合。
此外,本领域技术人员可以理解,本申请的各方面可以通过若干具有可专利性的种类或情况进行说明和描述,包括任何新的和有用的工序、机器、产品或物质的组合或对他们的任何新的和有用的改进。相应地,本申请的各个方面可以完全由硬件执行、可以完全由软件(包括固件、常驻软件、微码等)执行、也可以由硬件和软件组合执行。以上硬件或软件均可被称为“数据块”、模块”、“引擎”、“单元”、“组件”或“系统”。此外,本申请的各方面可能表现为位于一个或多个计算机可读介质中的计算机产品,该产品包括计算机可读程序编码。
此外,除非权利要求中明确说明,本申请处理元素和序列的顺序、数字字母的使用或其他名称的使用,并非用于限定本申请流程和方法的顺序。尽管上述披露中通过各种示例讨论了一些目前认为有用的发明实施例,但应当理解的是,该类细节仅起到说明的目的,附加的权利要求并不仅限于披露的实施例,相反,权利要求旨在覆盖所有符合本申请实施例实质和范围的修正和等价组合。例如,虽然以上所描述的系统组件可以通过硬件设备实现,但是也可以只通过软件的解决方案得以实现,如在现有的服务器或移动设备上安装所描述的系统。
同理,应当注意的是,为了简化本申请披露的表述,从而帮助对一个或多个发明实施例的理解,前文对本申请实施例的描述中,有时会将多种特征归并至一个实施例、附图或对其的描述中。但是,这种披露方法并不意味着本申请对象所需要的特征比权利要求中提及的特征多。实际上,实施例的特征要少于上述披露的单个实施例的全部特征。
一些实施例中使用了描述成分、属性数量的数字,应当理解的是,此类用于实施例描述的数字,在一些示例中使用了修饰词“大约”、“近似”或“大体上”等来修饰。除非另外说明,“大约”、“近似”或“大体上”表明数字允许有±20%的变化。相应地,在一些实施例中,说明书和权 利要求中使用的数值数据均为近似值,该近似值根据个别实施例所需特点可以发生改变。在一些实施例中,数值数据应考虑规定的有效数位并采用一般位数保留的方法。尽管本申请一些实施例中用于确认其范围广度的数值域和数据为近似值,在具体实施例中,此类数值的设定在可行范围内尽可能精确。
最后,应当理解的是,本申请中实施例仅用以说明本申请实施例的原则。其他的变形也可能属于本申请的范围。因此,作为示例而非限制,本申请实施例的替代配置可视为与本申请的教导一致。相应地,本申请的实施例不仅限于本申请明确介绍和描述的实施例。
