In order to make the high-frequency far-field sound smaller, the distance between the two sound sources in the second set of dual sound sources can be set to a smaller value. Because the wavelength of the high-frequency signal is short, the small distance between the two sound sources can avoid the formation of a large phase difference in the far field, thus avoiding the formation of large sound leakage. The distance between the second set of dual sound sources is less than the distance between the first set of dual sound sources.

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,在描述本发明中声音传导相关技术时,将采用“播放器”、“扬声器装置”、“扬声装置”或“扬声器”的描述。该描述仅仅为声音传导应用的一种形式,对于该领域的普通技术人员来说,“播放器”、“播放装置”、“扬声装置”、“扬声器装置”或“助听器”也可用其他同类词语代替。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,在了解扬声器的基本原理后,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,扬声器中加入环境声音拾取和处理功能,使该扬声器实现助听器的功能。例如,在使用骨传导扬声器的情况下,加入可以拾取使用者/佩戴者周围环境的声音的麦克风等传声器,在一定的算法下,将声音处理后(或者产生的电信号)传送至骨传导扬声器部分。即,骨传导扬声器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骨传导扬声器部分将声音传递给使用者/佩戴者,从而实现骨传导助听器的功能。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。
图1为扬声器装置导致人耳产生听觉的过程。扬声器装置通过其自带的扬声器可以通过骨传导或者气传导的方式将声音传递给听力***,从而产生听觉。如图1所示,扬声器装置使人耳产 生听觉的过程主要包括以下几个步骤:
在步骤101中,扬声器装置可以获取或者产生含有声音信息的信号。在一些实施例中,声音信息可以指具有特定数据格式的视频、音频文件,也可以指一般意义上能够携带最终可通过特定途径转化为声音的数据或文件。在一些实施例中,含有声音信息的信号可以来自于扬声器装置本身的存储单元,也可以来自于扬声器装置以外的信息产生、存储或者传递***。此处所讨论的声音信号并不局限于电信号,也可包括电信号之外的其它形式的如光信号、磁信号、机械信号等。原则上,只要该信号包含有扬声器装置可以用以产生声音的信息,均可作为声音信号进行处理。在一些实施例中,声音信号也不局限于一个信号源,可以来自于多个信号源。这些多个信号源可以相关也可以相互无关。在一些实施例中,声音信号传递或产生的方式可以是有线的也可以是无线的,可以是实时的也可以是延时的。例如,扬声器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,也可以直接从存储介质上获取数据,产生声音信号。以骨传导技术作为示例性说明,在骨传导扬声器中可以加入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。其中,有线连接包括但不限于使用金属电缆、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、和双绞线。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。
这里所说的存储设备/存储单元,包括直接连接存储(Direct Attached Storage),网络附加存储(Network Attached Storage)和存储区域网络(Storage Area Network)等存储***上的存储设备。存储设备包括但不限于常见的各类存储设备如固态存储设备(固态硬盘、固态混合硬盘等)、机械硬盘、USB闪存、记忆棒、存储卡(如CF、SD等)、其他驱动(如CD、DVD、HD DVD、Blu-ray等)、随机存储器(RAM)和只读存储器(ROM)。其中RAM有但不限于:十进计数管、选数管、延迟线存储器、威廉姆斯管、动态随机存储器(DRAM)、静态随机存储器(SRAM)、晶闸管随机存储器(T-RAM)、和零电容随机存储器(Z-RAM)等;ROM又有但不限于:磁泡存储器、磁钮线存储器、薄膜存储器、磁镀线存储器、磁芯内存、磁鼓存储器、光盘驱动器、硬盘、磁带、早期NVRAM(非易失存储器)、相变化内存、磁阻式随机存储式内存、铁电随机存储内存、非易失SRAM、闪存、电子抹除式可复写只读存储器、可擦除可编程只读存储器、可编程只读存储器、屏蔽式堆读内存、浮动连接门随机存取存储器、纳米随机存储器、赛道内存、可变电阻式内存、和可编程金属化单元等。以上提及的存储设备/存储单元是列举了一些例子,该存储设备/存储单元可以使用的存储设备并不局限于此。
在步骤102中,扬声器装置可以将含有声音信息的信号转换成振动并产生声音。振动的产生伴随着能量的转换,扬声器装置可以使用特定的换能装置实现信号向机械振动转换。转换的过程中可能包含多种不同类型能量的共存和转换。例如,电信号通过换能装置可以直接转换成机械振动,产生声音。再例如,声音信息包含在光信号中,一种特定的换能装置可以实现由光信号转换为振动 信号的过程。其它可以在换能装置工作过程中共存和转换的能量类型包括热能、磁场能等。在一些实施例中,换能装置的能量转换方式包括但不限于动圈式、静电式、压电式、动铁式、气动式、电磁式等。扬声器装置的频率响应范围以及音质会受到不同换能方式以及换能装置中各个物理组件性能的影响。例如,在动圈式换能装置中,缠绕的柱状线圈与振动板相连,受信号电流驱动的线圈在磁场中带动振动板振动发声,振动板材质的伸展和收缩、褶皱的变形、大小、形状以及固定方式,永磁体的磁密度等,都会对扬声器装置最终的音效质量带来很大的影响。
这里使用的术语“音质”可以理解为能够反映出声音的质量,指经处理、传输等过程后音频的保真度。在声音设备中,音质通常包含几个方面的内容,包括音频的强度和幅度、音频的频率、音频的泛音或谐波成分等。在评定声音音质时,既有客观评价音质的测量方法和评价标准,也有结合声音不同要素和主观感受来评价音质各种属性的方法,因此声音的产生、传递以及接收过程都会一定程度上影响声音的音质。
在步骤103中,声音通过传递***进行传递。在一些实施例中,传递***是指可以传递包含声音信息的振动信号的物质,例如,人或/和有听力***的动物的颅骨、骨迷路、内耳淋巴液、螺旋器。又例如,可以传递声音的介质(例如,空气、液体)。仅仅为了说明声音信息通过传递***进行传递的过程,以骨传导扬声器作为示例性说明,骨传导扬声器可以将电信号转化的声波(振动信号)直接通过骨头传至听觉中枢。此外还可以通过气传导的方式将声波传递至听觉中枢,关于气传导的内容请参见本说明书中其他地方的具体描述。
在步骤104中,声音信息被传递至传感终端。具体地,声音信息通过传递***传递给传感终端。在一种工作场景中,扬声器装置拾取或产生含有声音信息的信号,通过换能装置将声音信息转换成声音振动,并通过传递***将声音传递给传感终端,最终听到声音。不失一般性,以上描述的传感终端、听力***、感觉器官等的主体可以是人,也可以是具有听力***的动物。需要注意的是,以下对于人类使用扬声器装置的描述并不构成对扬声器装置使用场景的限制,类似的描述同样可以适用于其它动物。
以上对扬声器装置大致流程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,在步骤101获取含有声音信息的信号和步骤102声音产生之间,可以额外加入信号修正或强化步骤,该步骤可以将101中获取的信号根据特定的算法或参数进行强化或者修正。更进一步的,在步骤102声音产生和103声音传递步骤之间,可以额外加入振动强化或修正步骤。
本申请说明书中的扬声器装置可以包括但不限于耳机、MP3播放器、助听器。本申请的以下具体实施方式中以MP3播放器为例,对扬声器装置进行具体说明。图2是根据本申请一些实施例提供的MP3播放器的***结构示意图,图3是根据本申请一些实施例提供的MP3播放器中耳挂的部分结构示意图,图4是图3中A部分的局部放大图。如图1所示,在一些实施例中,MP3播放器 可以包括耳挂10、机芯壳体20、电路壳体30、后挂40、耳机芯50、控制电路60以及电池70。其中,机芯壳体20与电路壳体30分别设置于耳挂10的两端,后挂40则进一步设置于电路壳体30远离耳挂10的一端。机芯壳体20的数量为两个,分别用于容纳耳机芯50,电路壳体30的数量也为两个,分别用来容纳控制电路60和电池70,后挂40的两端分别连接对应的电路壳体30。其中,耳挂10是指在用户佩戴骨传导MP3播放器时,用于环绕并支撑于用户的耳根部位,进而将机芯壳体20及耳机芯50悬挂并固定于用户耳朵预定位置的结构。
结合图2、图3和图4,在一些实施例中,耳挂10包括弹性金属丝11、导线12、固定套管13以及设置于弹性金属丝11两端的接插端14和接插端15。在一些实施例中,耳挂10还可以包括保护套管16以及与保护套管16一体成型的壳体护套17。其中,弹性金属丝11主要用于使耳挂10保持为与用户耳朵匹配的形状,并具有一定的弹性,从而能够在用户佩戴时根据用户的耳型以及头型产生一定的弹性形变以适配不同耳型以及头型的用户。在一些实施例中,弹性金属丝11可以由记忆合金制成,具有良好的变形恢复能力,从而即便是耳挂10受到外力作用产生形变,在外力去除时,仍然能够恢复至原来的形状以能够继续为用户所使用,从而延长MP3播放器的使用寿命。在其它实施例中,弹性金属丝11也可以由非记忆合金制成。导线12可以用于与耳机芯50以及控制电路60、电池70等进行电连接,以为耳机芯50的工作进行电量供应以及数据传输。
固定套管13用于将导线12固定于弹性金属丝11上。本实施方式中,固定套管13为至少两个,至少两个固定套管13可沿弹性金属丝11以及导线12的走向而间隔设置,并通过包裹设置在导线12以及弹性金属丝11的***而将导线12固定于弹性金属丝11上。
在一些实施例中,接插端14和接插端15可由硬质材料,如塑胶等制成。在一些实施例中,在制作该接插端14和接插端15时,可以分别以注塑的方式将二者形成于弹性金属丝11的两端。在一些实施例中,也可以先对接插端14和接插端15分别进行注塑,并在注塑时分别预留与弹性金属丝11端部的连接孔,从而在注塑完成后,通过连接孔而将该接插端14和接插端15分别插接在弹性金属丝11的对应的端部,或者并通过粘接的方式进行固定均可。
需要指出的是,在本实施方式中,接插端14和接插端15可以不直接注塑形成在导线12的***,而是在注塑时避开导线12。具体地,可以在注塑接插端14和接插端15时,对位于弹性金属丝11两端的导线12进行固定,以远离接插端14和接插端15的位置,并进一步在接插端14和接插端15上分别设置第一走线通道141和第二走线通道151,以在注塑完成后,将导线12沿第一走线通道141和第二走线通道151延伸设置。具体地,在形成第一走线通道141和第二走线通道151后,可将导线12以穿线的方式穿入该第一走线通道141和第二走线通道151。在一些实施例中,也可以根据实际情况,将接插端14和接插端15直接注塑在导线12的***,此处不做具体限定。
在一些实施例中,第一走线通道141可以包括第一走线槽1411和连通第一走线槽1411的第一走线孔1412。其中,第一走线槽1411连通接插端14的侧壁面设置,第一走线孔1412的一端与第一走线槽1411的一端连通,另一端与接插端14的外端面连通。接插端14处的导线12沿第一走线槽1411和第一走线孔1412延伸并外露于接插端14的外端面,以进一步与其它结构连接。
在一些实施例中,第二走线通道151可包括第二走线槽1511和连通第二走线槽1511的第二走线孔1512。其中,第二走线槽1511连通接插端15的侧壁面设置,第二走线孔1512的一端与第二走线槽1511的一端连通,另一端与接插端15的外端面连通。接插端15处的导线12沿第二走线槽1511和第二走线孔1512延伸并外露于接插端15的外端面,以进一步与其它结构连接。
在一些实施例中,接插端14的外端面是指接插端14远离接插端15的一端的端面;相应地,接插端15的外端面是指接插端15远离接插端14的一端的端面。
在一些实施例中,保护套管16可注塑形成于弹性金属丝11、导线12、固定套管13、接插端14和接插端15的***,从而将保护套管16分别与弹性金属丝11、导线12、固定套管13、接插端14和接插端15固定连接,而无需将保护套管16单独注塑形成后再进一步套装在弹性金属丝11以及接插端14、接插端15的***,从而能够简化制作及装配工序,且通过这种方式,能够使得保护套管16的固定更加牢靠、稳定。
在一些实施例中,在成型保护套管16时,同时与该保护套管16一体成型有设置于靠近接插端15一侧的壳体护套17。在一些实施例中,壳体护套17可与保护套管16一体成型而成为一整体,电路壳体30可通过与接插端15的接插固定而连接设置在耳挂10的一端,壳体护套17则可进一步以套装的方式包覆于在电路壳体30的***。
具体地,在制造MP3播放器的耳挂10时,可通过如下步骤实现:
步骤S101:利用固定套管13将导线12固定于弹性金属丝11上,其中在弹性金属丝11的两端预留出注塑位。具体地,可以先将弹性金属丝11与导线12按照预设的方式,如并排放置在一起,然后,将固定套管13进一步套设在导线12与弹性金属丝11的***,从而将导线12固定在弹性金属丝11上。其中,由于弹性金属丝11的两端还需要注塑接插端14和接插端15,因此,在固定时,弹性金属丝11的两端不能被固定套管13完全包裹,而需预留出对应的注塑位,以供接插端14和接插端15注塑占用。
步骤S102:在弹性金属丝11的两端的注塑位上分别注塑接插端14和接插端15,其中接插端14和接插端15分别设置有第一走线通道141和第二走线通道151。
步骤S103:将导线12设置成沿第一走线通道141和第二走线通道151延伸。具体地,此处可在接插端14和接插端15成型完成后,进一步通过手动或者通过机器将导线12的两端分别穿入第一走线通道141和第二走线通道151。其中,导线12位于第一走线通道141和第二走线通道151之间的部分由固定套管13固定于弹性金属丝11上。
步骤S104:在弹性金属丝11、导线12、固定套管13、接插端14和接插端15的***注塑形成保护套管16。
在一些实施例中,在执行步骤S104时,进一步以注塑的方式形成与接插端15***的保护套管16一体成型的壳体护套17。
需要指出的是,在一些实施例中,也可以在安装固定套管13时先不设置导线12,而在接插端14和接插端15注塑之后,再进一步设置导线12,具体步骤如下:
步骤S201:将固定套管13套设于弹性金属丝11上,其中在弹性金属丝11的两端预留出注塑位。
步骤S202:在弹性金属丝11的两端的注塑位上分别注塑接插端14和接插端15,其中接插端14和接插端15分别设置有第一走线通道141和第二走线通道151。
步骤S203:将导线12穿设于固定套管13的内部,以利用固定套管13将导线12固定于弹性金属丝11上,并进一步将导线12设置成沿第一走线通道141和第二走线通道151延伸。
需要指出的是,通过这种方式,能够避免在对接插端14和接插端15注塑时受到导线12的干扰,从而有利于成型的顺利进行。
需要指出的是,上述实施方式中方法所涉及到的弹性金属丝11、导线12、固定套管13、接插端14、接插端15与保护套管16的结构、作用以及形成方式等均与上述实施方式中的相同,相关详细内容请参见上述实施方式,此处不再赘述。
在一些实施例中,机芯壳体20可用于容纳耳机芯50,并与接插端14接插固定。其中,耳机芯50和机芯壳体20的数量均为两个,分别对应用户的左耳和右耳。
在一些实施例中,机芯壳体20可以与接插端14通过插接、卡接等方式连接,以将机芯壳体20与耳挂10固定在一起。也就是说,本实施方式中,耳挂10与机芯壳体20可先分别成型,然后再进一步装配在一起,而不是将二者一体直接成型。
通过这种方式,可以采用各自对应的模具对耳挂10和机芯壳体20分别成型,而无需采用同一个较大尺寸的模具将二者一体成型,从而可减小模具的尺寸,以降低模具的加工难度,以及成型难度;另外,由于耳挂10和机芯壳体20分别采用不同的模具加工,在生产制造过程中,在需要对耳挂10或机芯壳体20中的某一个的形状或者构造进行调整时,仅调整该结构对应的模具即可,而无需对另外一个结构的模具进行调整,从而能够降低生产成本。当然,在其它实施方式当中,也可以根据情况而使耳挂10与机芯壳体20通过一体成型得到。
在一些实施方式中,机芯壳体20设置有与机芯壳体20的外端面21连通的接插孔22。其中,机芯壳体20的外端面21是指机芯壳体20朝向耳挂10的端面。接插孔22用于为耳挂10的接插端14***机芯壳体20提供容置空间,以便进一步实现接插端14与机芯壳体20的接插固定。

结合图2、图5和图6,在一些实施例中,接插端14可以包括***部142和两个弹性卡勾143。具体地,***部142至少部分***于接插孔22内并抵接于止挡块23的外侧面231上。其中,***部142的外侧壁的形状与接插孔22的内侧壁的形状匹配,以使得***部142至少部分***于接插孔22内时,使得***部142的外侧壁与接插孔22的内侧壁抵接。
止挡块23的外侧面231是指止挡块23朝向耳挂10设置的一侧面。***部142可进一步包括一朝向机芯壳体20的端面1421,该端面1421可与止挡块23的外侧面231匹配,从而在***部142至少部分***于接插孔22内时,***部142的端面1421与止挡块23的外侧面231抵接。
在一些实施例中,两个弹性卡勾143可沿垂直于***方向并排并间隔且对称设置于***部142朝向机芯壳体20内部的一侧。其中,每个弹性卡勾143可分别包括梁部1431和勾部1432,梁部1431与***部142朝向机芯壳体20的一侧连接,勾部1432设置在梁部1431远离***部142的一端,并沿垂直于***方向延伸。进一步地,每个勾部1432设置有连接平行于***方向的侧面与远离***部142的端面的过渡斜面14321。
在一些实施例中,在机芯壳体20与接插端14接插固定后,***部142部分***于接插孔22内,且在***部142的外露部分呈阶梯状设置,进而形成与机芯壳体20的外端面21间隔设置的环形台面1422。***部142的外露部分是指***部142外露于机芯壳体20的部分,具体地,可以是指外露于机芯壳体20且靠近机芯壳体20外端面的部分。
在一些实施例中,环形台面1422可以与机芯壳体20的外端面21相对设置,且二者之间的间隔可以是指沿接插方向间隔以及沿垂直于接插方向的间隔。
在一些实施例中,保护套管16可以延伸至环形台面1422朝向机芯壳体20的外端面21的一侧,并在机芯壳体20的接插孔22与接插端14接插固定时,填充于环形台面1422与机芯壳体20的外端面21之间的间隔内,并与机芯壳体20弹性抵接,从而使得外部液体难以从接插端14与机芯壳体20之间的接合处进入机芯壳体20内部,进而实现接插端14与接插孔22之间的密封,以保护机芯壳体20内部的耳机芯50等,从而能够提高对骨传导MP3播放器的防水效果。
具体地,在一些实施例中,保护套管16在环形台面1422朝向机芯壳体20的外端面的21一侧形成一环形抵接面161。其中,该环形抵接面161为保护套管16朝向机芯壳体20一侧的端面。
其中,环形台面1422可以与机芯壳体20的外端面21相对设置,且二者之间的间隔可以是指沿接插方向间隔以及沿垂直于接插方向的间隔。
进一步地,保护套管16延伸至环形台面1422朝向机芯壳体20的外端面21的一侧,并在机芯壳体20的接插孔22与接插端14接插固定时,填充于环形台面1422与机芯壳体20的外端面21之间的间隔内,并与机芯壳体20弹性抵接,从而使得外部液体难以从接插端14与机芯壳体20之间的接合处进入机芯壳体20内部,进而实现接插端14与接插孔22之间的密封,以保护机芯壳体20内部的耳机芯50等,从而能够提高对骨传导MP3播放器的防水效果。
在一些实施例中,保护套管16在环形台面1422朝向机芯壳体20的外端面的21一侧形成一环形抵接面161。其中,该环形抵接面161为保护套管16朝向机芯壳体20一侧的端面。
在一些实施例中,保护套管16还可以包括位于该环形抵接面161内部且相对于环形抵接面161凸出设置的环形凸台162。具体地,该环形凸台162具体形成于环形抵接面161朝向接插端14的一侧,并相对于该环形抵接面161沿朝向机芯壳体20的方向凸出设置,进一步地,该环形凸台162还可直接形成于环形台面1422的***,并覆盖该环形台面1422。
在一些实施例中,机芯壳体20可以包括用于连接机芯壳体20的外端面21和接插孔22的内侧壁的连接斜面24。该连接斜面24具体为机芯壳体20的外端面21与接插孔22的内侧壁之间的过渡面,该连接斜面24与机芯壳体20的外端面21和接插孔22的内侧壁均不在同一平面上。在一 些实施例中,连接斜面24可以为平面,或者也可以根据实际需求而设置成曲面,或者其它形状,此处不做具体限定。
具体地,在机芯壳体20与接插端14接插固定时,环形抵接面161和环形凸台162分别与机芯壳体20的外端面和连接斜面24弹性抵接。需要指出的是,由于机芯壳体20的外端面21和连接斜面24不在同一平面上,从而使得保护套管16与机芯壳体20之间的弹性抵接处不位于同一平面上,从而使得外部液体难以由保护套管16与机芯壳体20之间进入机芯壳体20以进一步进入耳机芯50,从而能够提高MP3播放器的防水效果,以对内部功能结构起到保护作用,进而延长MP3播放器的使用寿命。
在一些实施例中,***部142在环形台面1422朝向机芯壳体20的外端面21的一侧进一步形成有与环形台面1422邻接的环形凹槽1423,其中,环形凸台162可形成于环形凹槽1423内。
在一些实施例中,耳挂10的导线12的位于机芯壳体20的外部的一端可穿过第二走线通道151而进一步连接电路壳体30所容纳的控制电路60、电池70等机芯壳体20外部的外部电路,另一端则沿第一走线通道141而露出于接插端14的外端面,并进一步随***部142而通过接插孔22而进入机芯壳体20内部。
图7是根据本申请一些实施例提供的机芯壳体的部分结构示意图,图8是图7中D部分的局部放大图,图9是根据本申请一些实施例提供的机芯壳体的局部截面图。
结合图2、图7、图8以及图9,在一些实施例中,机芯壳体20可以包括主壳体25以及隔板组件26。其中,隔板组件26位于主壳体25内部,并与主壳体25连接,进而将主壳体25的内部空间27分隔成第一容置空间271和靠近接插孔22一侧的第二容置空间272。在一些实施例中,主壳体25可以包括周侧壁251以及与周侧壁251的一端面连接的底端壁252,周侧壁251与底端壁252共同围绕形成一主壳体25的内部空间27。
隔板组件26位于主壳体25的靠近接插孔22的一侧,并包括侧隔板261以及底隔板262。其中,侧隔板261可沿垂直于底端壁252的方向设置,且侧隔板261的两端均与周侧壁251连接,从而对主壳体25的内部空间27进行分隔。底隔板262可与底端壁252平行或者接***行且间隔设置,并进一步分别与周侧壁251和侧隔板261连接,从而将主壳体25所形成的内部空间27一分为二而形成由侧隔板261、底隔板262和远离接插孔22的周侧壁251、底端壁252共同围成的第一容置空间271,以及由底隔板262与侧隔板261和靠近接插孔22的周侧壁251共同围成的第二容置空间272。其中,第二容置空间272可小于第一容置空间271。当然,隔板组件26也可以通过其它的设置方式对主壳体25的内部空间27进行划分,此处不做具体限定。
在一些实施例中,耳机芯包括功能组件51,该功能组件51设置于第一容置空间271内,可用于振动发声。在一些实施例中,MP3播放器还可以包括与功能组件51连接的导线80,该导线80的另一端可由第一容置空间271而延伸至第二容置空间272内。
在一些实施例中,侧隔板261可在远离底端壁252的顶部边缘设置走线槽2611,该走线槽2611可连通第一容置空间271和第二容置空间272。进一步地,导线12的远离功能组件的一端经 由该走线槽延伸至第二容置空间272内。
导线12的远离电路壳体30的一端随***部142进入机芯壳体20内部后,可进一步延伸入第二容置空间272内,并在第二容置空间272内与导线80电连接,以形成从第一容置空间271经由第二容置空间272而连接至外部电路的导线通路,从而通过该导线通路将功能组件51与位于机芯壳体20外部的外部电路电连接。
在一些实施例中,底隔板262上还可以设置有走线孔2621,该走线孔2621将接插孔22与第二容置空间272连通,从而使得由接插孔22进入机芯壳体20的导线12能够经由该走线孔2621而延伸至第二容置空间272。
其中,导线12与导线80在第二容置空间272内连接后,盘绕设置于第二容置空间272内。具体可通过焊接的方式将导线12与导线80连接于一起,进而将功能组件51与外部电路电连接,以通过外部电路为功能组件51的正常工作提供电量或者为耳机芯50传输数据。
需要指出的是,在对骨传导MP3播放器装配时,导线往往会长于实际需求,以便于装配。然而耳机芯50处多余的导线若不能够进行合理的放置,则容易在功能组件51工作时产生振动而发出异响,从而降低骨传导MP3播放器的声音质量,从而影响用户的听音感受。本实施方式中,在机芯壳体20的主壳体25所形成的内部空间27当中分离出第二容置空间272以用于容置多余的导线12和导线80,从而避免或者减少多余的导线对因振动而对骨传导MP3播放器所发出的声音的影响,以提高声音质量。
在一些实施例中,隔板组件26进一步包括内隔板263,内隔板263进一步将第二容置空间272分隔成两个子容置空间2721。具体地,该内隔板263垂直于主壳体25的底端壁252设置,分别与侧隔板261和周侧壁251连接,并进一步延伸至走线孔2621处,从而在将第二容置空间272分隔为两个子容置空间2721的同时,还进一步将走线孔2621划分为两个,两个走线孔2621可分别与对应的子容置空间2721连通。
本实施方式中,导线12和导线80可分别为两根,其中两根导线12分别沿对应的走线孔2621而分开延伸至各自的子容置空间2721内,而两根导线80则仍一起通过走线槽2611而进入第二容置空间272,并在进入第二容置空间272后分开,并分别在对应的子容置空间2721内与对应的导线12焊接于一起,并进一步盘绕设置于对应的子容置空间2721内。
在一些实施例中,第二容置空间272可进一步由密封胶进行填充。通过这种方式,能够将第二容置空间272内所容置的导线12和导线80进一步固定,以进一步降低由于导线振动而对声音质量造成的不良影响,从而提高骨传导MP3播放器的声音质量,同时能够对导线12与导线80之间的焊接点起到保护作用,另外,将第二容置空间272密封设置还能够达到防水防尘的目的。
参照图2和图3,在一些实施例中,电路壳体30与接插端15接插固定,从而将电路壳体30固定在耳挂10远离机芯壳体20的一端。其中,在用户佩戴使用时,容纳电池70的电路壳体30和容纳控制电路60的电路壳体30可分别对应用户的左侧和右侧,二者在与对应的接插端15的接插方式上可以不同。
具体地,电路壳体30可以与接插端15通过插接、卡接等方式连接。也就是说,本实施方式中,耳挂10与电路壳体30可先分别独立成型,然后并在成型完成后再进一步装配在一起,而不是直接将二者一体成型。
通过这种方式,可以采用各自对应的模具对耳挂10和电路壳体30分别成型,而无需采用同一个较大尺寸的模具将二者一体成型,从而可减小成型模具的尺寸,以降低模具的加工难度,以及成型难度;另外,由于耳挂10和电路壳体30分别采用不同的模具加工,在生产制造过程中,在需要对耳挂10或电路壳体30中的某一个的形状或者构造进行调整时,仅调整该结构对应的模具即可,而无需对另外一个结构的模具进行调整,从而能够降低生产成本。
在一些实施例中,电路壳体30设置有接插孔31,该接插孔31的内表面的形状可与接插端15的至少部分外表面的形状匹配,从而使得接插端15能够至少部分***至接插孔31内。
进一步地,在接插端15的相对两侧分别设置有与接插端15相对于接插孔31的***方向垂直设置的开槽152。具体地,两个开槽152对称且间隔设置于接插端15的相对两侧,且均在沿***方向的垂直方向上连通接插端15的侧壁。
参照图2,电路壳体30可以呈扁平状设置,例如,电路壳体30于第二接插孔31处的横截面可以为椭圆形,或者能够形成扁平状设置的其它形状。本实施方式中,电路壳体30的面积较大的两个相对设置的侧壁为主侧壁33,连接两个主侧壁33的面积较小的且相对设置的两对侧壁为辅侧壁34。
需要注意的是,以上对MP3播放器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MP3播放器的基本原理后,可能在不背离这一原理的情况下,对实施MP3播放器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,固定套管13的数量不限于上述实施例中所述的至少两个,其数量也可以为一个,具体可根据实际需求而定。又例如,接插孔31处的横截面的形状不限于椭圆形,还可以为其它形状,如三角形、四边形、五边形等多边形。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,扬声器装置可以包括但不限于耳机、MP3播放器、助听器等。基于上述的扬声器装置,如图2所示,在一些实施例中,机芯壳体20在扬声器装置的位置可以是不固定的,机芯壳体20可以贴合用户脸颊的不同部位(例如耳前、耳后等),使用户感受到不同的音质,用户可根据自己的喜好自行调节,还可方便不同头型大小的用户使用。例如,图2所示的扬声器装置通过耳挂10固定在人耳上,机芯壳体20位于耳前。在一些实施例中,耳挂10可以是弹性可发生形变的,将耳挂10进行折弯以改变机芯壳体20在人体的贴合位置。在一些实施例中,耳挂10用于与机芯壳体20的连接端可以根据用户习惯的位置进行设置,例如,用户习惯将机芯壳体20位于耳后,可在保持耳挂10固定功能的前提下将耳挂10的连接端设置于耳后。关于耳挂10和机芯壳体20之间卡接的连接方式可以参考本申请其他地方的具体内容。需要注意的是,耳挂10与机芯壳体20之间的连接方式不限于上述的卡接,例如,耳挂10与机芯壳体20之间还可以通过铰接的方式(如, 铰链组件)进行连接,关于铰接的具体内容可以参考本申请其他地方的具体内容。
在一些实施例中,机芯壳体20可以贴合在使用者头部的任意位置,例如,头顶、额头、脸颊、鬓角、耳廓、耳廓背面等。在一些实施例中,骨传导耳机可以和头部的贴合方式可以为面贴合或者点贴合。贴合表面设有梯度结构,所述梯度结构指的是接触面表面存在高度变化的区域。梯度结构可以是接触面外侧(与使用者贴合的一侧)存在的凸起/凹下或者台阶状等结构,也可以是接触面内侧(背向使用者的一侧)存在的凸起/凹下或者台阶状等结构。
需要注意的是,以上对机芯壳体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,在了解贴合的基本原理后,可能在不背离这一原理的情况下,对实施贴合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,耳挂不限于图2中的形状,耳挂的形状可以根据机芯壳体与人体头部的贴合位置进行调整。诸如此类的变形,均在本申请的保护范围之内。
图10是根据本申请一些实施例提供的铰链组件的结构示意图,图11是根据本申请一些实施例提供的铰链组件的***结构示意图。如图10和图11所示,铰链组件可以包括铰链2530,铰链2530是用来连接两个固体并允许两者之间做相对转动的结构。在一些实施例中,耳挂10与机芯壳体20之间还可以通过铰接的方式进行连接。机芯壳体20与人体皮肤的贴合位置可以通过铰链组件进行调整。
请结合图2、图10和图11,铰链组件设置于耳挂10远离电路壳体30的端部,并进一步通过铰链2530将机芯壳体20连接至耳挂10远离电路壳体2530的端部。在一些实施例中,铰链组件还可以包括杆状件2540和固定件2550。在一些实施例中,铰链2530可以包括铰链座2531以及铰链臂2532。其中,铰链臂2532通过转轴2533与铰链座2531转动连接。容易理解地,铰链座2531与铰链臂2532可分别连接在需要转动连接的两个构件上,以使得两个构件通过铰链2530的转轴2533转动连接在一起。
在一些实施例中,铰链2530的铰链座2531连接设置在杆状件2540上。在一些实施例中,杆状件2540可以是通过铰链2530转动连接的两个构件中的一个的部分结构或者整体结构,或者也可以是需要转动连接的两个构件中的一个与铰链2530进行连接的连接结构。本实施方式中的铰链组件在用于扬声器装置时,杆状件2540可以为扬声器装置的耳挂的至少一部分,例如可以是耳挂10的全部,或者是耳挂10远离电路壳体30的一端的一部分,进而通过该部分耳挂10将铰链2530设置于耳挂远离电路壳体30的端部。
在一些实施例中,杆状件2540沿长度方向设置有与杆状件2540的端面连通的铰链腔2541,杆状件2540的侧壁上设置有与铰链腔2541连通的第一插置孔2542,铰链座2531的远离铰链臂2532的一端从杆状件2540的端面***至铰链腔2541,并由插置在第一插置孔2542内的固定件2550固定在铰链腔2541内。在本实施方式中,铰链腔2541连通耳挂10远离电路壳体30的端部的端面,从而使得铰链座2531***至铰链腔2541内而将铰链2530与耳挂10连接。
在一些实施例中,第一插置孔2542也可由杆状件2540在成型过程中形成,或者在成型后 进一步通过钻孔等方法在杆状件的侧壁上形成。在一些实施例中,第一插置孔2542的形状可以为圆形。在其它实施例中,第一插置孔2542的形状还可以为方形、三角形等其它形状。固定件2550的形状与第一插置孔2542匹配,以使得固定件2550能够从杆状件2540的外部***第一插置孔2542,并进而通过抵紧铰链座2531的侧壁的方式,或者进一步穿透铰链座2531的外壁以插接的方式等将铰链座2531固定在铰链腔2541内。在一些实施例中,第一插置孔2542的内壁与固定件2550的外壁上可以设置匹配的螺纹,以使得固定件2550可以通过螺接的方式与第一插置孔2542连接以进一步将铰链座2531固定在铰链腔2541内。在一些实施例中,第一插置孔2542与固定件2550还可以通过过盈配合等方式进行连接。
在一些实施例中,铰链臂2532还可与其它构件连接,从而使得该构件在于铰链臂2532连接后,进一步通过将铰链座2531装设在杆状件2540的铰链腔2541内从而与杆状件2540或者与杆状件2540连接的其它构件之间能够绕转轴2533进行转动。例如,铰链组件在应用于上述扬声器装置中时,机芯壳体20连接设置在铰链臂2532远离铰链座2531一端,从而通过铰链2530连接在耳挂10远离电路壳体30的端部。
在一些实施例中,杆状件2540上可以设置有与该杆状件2540的端面连通的铰链腔2541,铰链2530通过将铰链座252531容置于该铰链腔41内,并进一步将固定件2550通过第一插置孔2542穿透杆状件2540的侧壁从而将容置于铰链腔2541内的铰链座2531固定在铰链腔2541内,从而可以实现铰链2530相对于杆状件2540可拆装,以方便铰链2530或者杆状件2540的更换。在本实施例中,扬声器装置可以实现铰链2530与机芯壳体20相对于耳挂10可拆装,从而在机芯壳体20或耳挂10损坏时,便于进行更换。
在一些实施例中,铰链座2531上设置有与第一插置孔2542对应的第二插置孔25311,固定件2550进一步插置于第二插置孔25311内。在一些实施例中,第二插置孔25311的形状与固定件2550匹配,以使得固定件2550在穿过第一插置孔2542后,进一步***第二插置孔25311中以将铰链座2531固定,从而减少铰链座2531在铰链腔2541内的晃动,使得铰链2530固定得更加牢固。在一些实施例中,第二插置孔25311的内侧壁上可设置有与固定件2550对应的外壁上互相匹配的螺纹,以使得固定件2550与铰链座2531螺接在一起。在一些实施例中,第二插置孔25311的内壁与固定件2550的对应接触的位置处的外侧壁均为平滑的面,固定件2550与第二插置孔25311过盈配合,此处不做具体限定。在一些实施例中,第二插置孔25311还可贯穿铰链座2531的两侧边设置,从而使得固定件2550能够进一步穿透整个铰链座2531,以将铰链座2531更加牢固得固定在铰链腔2541内。
在一些实施例中,在垂直于杆状件2540的长度方向的截面上,铰链座2531的截面形状与铰链腔2541的截面形状相匹配,以使得在***后铰链座2531与杆状件2540之间形成密封配合。在一些实施例中,铰链座2531的截面形状和铰链腔2541的截面形状可以为任意形状,只要能够使得铰链座2531从杆状件2540的远离铰链臂2532的端面***至该铰链腔2541中即可。进一步地,第一插置孔2542设置在铰链腔2541的侧壁上,并贯通铰链腔2541的侧壁与铰链腔2541连通。
在一些实施例中,铰链座2531的截面形状和铰链腔2541的截面形状均呈矩形设置,第一插置孔2542垂直于矩形的一侧边设置。在一些实施例中,铰链座2531外侧壁的棱角或铰链腔2541的内侧壁的角可以做倒圆角设置,使得铰链座2531与铰链腔2541的接触更加平滑,从而使得铰链座31能够顺利得***至铰链腔2541内。
在一些实施例中,铰链组件还可以包括设置于铰链2530外侧的连接线。在一些实施例中,连接线可以为具有电性连接作用和/或机械连接作用的连接线。铰链组件用于将机芯壳体20与耳挂10远离电路壳体30的端部进行连接,而与机芯壳体20相关的控制电路等可设置于耳挂10或电路壳体30中。连接线可以将机芯壳体20与耳挂10或电路壳体30中的控制电路等进行电连接。具体地,连接线可位于铰链座2531和铰链臂2532的一侧,与铰链2530设置于同一容置空间当中。
进一步地,铰链座2531包括第一端面,铰链臂2532具有与第一端面相对设置的第二端面,容易理解地,第一端面和第二端面之间存在一定的间隙,以使得铰链座2531和铰链臂2532能够绕转轴2533进行相对转动。本实施方式中,在铰链臂2532与铰链座2531进行相对转动过程中,第一端面与第二端面之间也随之发生相对位置的变化,从而使得二者之间的间隙变大或者变小。
在一些实施例中,第一端面与第二端面之间的间隙始终保持为大于或小于连接线的直径,从而使得位于铰链2530外侧的连接线不至于在铰链座2531与铰链臂2532的相对转动过程中夹入第一端面与第二端面之间的间隙中,进而减少铰链对连接线2560的损伤。在一些实施例中,第一端面与第二端面之间的间隙在铰链臂2532与铰链座2531进行相对转动过程中与连接线的直径的比例可始终保持为大于1.5或小于0.8,例如大于1.5、1.7、1.9、2.0等,或小于0.8、0.6、0.4、0.2等,此处不做具体限定。
图12是根据本申请一些实施例提供的铰链组件的结构示意图,图13是根据本申请一些实施例提供的铰链组件的局部截面图。如图12和图13所示,在一些实施例中,铰链组件还可进一步包括保护套管70。保护套管70套设在铰链2530的***,并随铰链2530发生弯折。在一些实施例中,保护套管70包括沿保护套管70的长度方向间隔设置的多个环状凸脊部71以及设置于环状凸脊部71之间并用于连接相邻设置的两个环状凸脊部的环状连接部72。在一些实施例中,环状凸脊部71的管壁厚度大于环状连接部72的管壁厚度。保护套管70的长度方向与铰链2530的长度方向一致,保护套管70具体可沿铰链座2531和铰链臂2532的长度方向设置。该保护套管70可以由软质材料做成,例如软质的硅胶、橡胶等。
在一些实施例中,环状凸脊部71可由保护套管70的外侧壁进一步向外凸出形成,而环状凸脊部71对应的保护套管70的内侧壁的形状此处不做具体限定。例如,内侧壁可以为平滑的,或者内侧壁上对应环状凸脊部71的位置还可设置凹陷等。环状连接部72用于连接相邻的环状凸脊部71,具体连接于环状凸脊部71的靠近保护套管70内部的边缘区域,从而在保护套管70的外侧壁一侧可相对于环状凸脊部71呈凹陷设置。
在铰链2530的铰链座2531和铰链臂2532之间绕转轴2533相对转动时,铰链座2531和铰链臂2532之间的角度发生变化,从而使得保护套管70发生弯折。具体地,在保护套管70随铰链 2530发生弯折时,位于保护套管70所形成的弯折形状的外侧区域的环状凸脊部71和环状连接部72处于拉伸状态,而位于弯折形状的内侧区域的环状凸脊部71和环状连接部72处于挤压状态。
环状凸脊部71和环状连接部72的管壁厚度分别是指环状凸脊部71和环状连接部72所对应的保护套管70的内侧壁与外侧壁之间的厚度。在一些实施例中,环状凸脊部71的管壁厚度大于环状连接部72的管壁厚度,从而使得环状凸脊部71相对于环状连接部72更硬,从而在保护套管70处于弯折状态时,处于弯折形状的外部一侧的保护套管70处于拉伸状态,环状凸脊部71能够为保护套管70提供一定的强度支撑;同时,处于弯折状态的内部一侧的保护套管70区域受到挤压,环状凸脊部71还能够承受一定的挤压力,从而对保护套管70起到保护作用,提高保护套管70的稳定性,延长保护套管70的寿命。
在一些实施例中,保护套管70的形状与铰链2530所处的状态一致。在一个应用场景中,保护套管70的沿长度方向上且绕转轴转动的两侧都可能受到拉伸或者挤压。在另一个应用场景中,铰链2530的铰链座2531和铰链臂2532仅能够绕转轴2533在小于或等于180°的范围内进行转动,也就是说,保护套管70仅能够朝向一侧进行弯折,那么保护套管70的沿长度方向上的两侧中有一侧可受到挤压,另一侧可受到拉伸,此时,可以根据保护套管70两侧受力的不同,而将保护套管70受力不同的两侧设置为不同的结构。
在一些实施例中,环状凸脊部71在保护套管70处于弯折状态时朝向保护套管70所形成的弯折形状外部一侧的沿保护套管70长度方向的宽度大于朝向弯折形状内部一侧的沿保护套管70长度方向的宽度。沿保护套管70长度方向上,增大环状凸脊部71的宽度能够进一步提高保护套管的强度。在一些实施例中,铰链座2531和铰链臂2532之间的初始夹角的角度小于180°,若保护套管70的环状凸脊部71均匀设置,则会使得保护套管70在原始状态下便受到挤压。在该实施例中,对应于弯折状态时朝向弯折形状的外侧区域一侧的环状凸脊部71的宽度较大,从而能够扩大该侧保护套管70的长度,从而在提高保护套管70的强度的同时,还使得在保护套管70弯折时,在一定程度上减少拉伸侧的拉伸程度;同时,环状凸脊部71在保护套管70处于弯折状态时朝向弯折形状的内侧区域一侧的沿保护套管70长度方向的宽度较小,能够增大挤压的环状连接部72在保护套管70长度方向上的空间,从而能够在一定程度上缓解挤压侧的挤压。
在一些实施例中,环状凸脊部71的宽度在从朝向弯折形状的外侧区域一侧向朝向弯折形状的内部区域一侧逐渐变小,从而使得保护套管70处于弯折状态时朝向保护套管70所形成的弯折形状的外侧区域一侧的宽度大于朝向弯折形状的内侧区域一侧的宽度。环状凸脊部71围绕设置在保护套管70的***,在保护套管70的长度方向上,一侧对应拉伸侧,另一侧对应挤压侧。本实施方式中,环状凸脊部71的宽度从朝向弯折形状的外侧区域一侧向朝向弯折形状的内侧区域一侧逐渐变小,从而使得宽度的较为均匀,能够在一定程度上提高保护套管70的稳定性。
在一些实施例中,环状凸脊部71在保护套管70处于弯折状态时朝向保护套管70所形成的弯折形状的外侧区域一侧的保护套管70内部的内环面设置有凹槽711。凹槽711沿垂直于保护套管70的长度方向设置,进而使得对应的环状凸脊部71在保护套管70在长度方向上受到拉伸时能 够进行适当的伸展。在保护套管70处于弯折状态时,朝向保护套管70所形成的弯折形状外部一侧的保护套管70处于拉伸状态,在对应的环状凸脊部71对应的保护套管70内部的内环面上设置凹槽711,从而能够在该侧保护套管拉伸时,凹槽711对应的环状凸脊部71能够适当伸展以承担部分拉伸,从而减少该侧保护套管所受到的拉力,进而对保护套管70起到保护作用。
需要指出的是,在保护套管70处于弯折状态时,朝向弯折形状的内侧区域的一侧的环状凸脊部71可在对应的保护套管70的内侧壁上不设置凹槽711。在一些实施例中,凹槽71沿保护套管70长度方向的宽度在从朝向弯折形状的外侧区域一侧向朝向弯折形状的内侧区域一侧逐渐变小,从而使得在朝向弯折形状的内侧区域一侧的环状凸脊部71所对应的保护套管70的内侧壁上没有凹槽711设置。
具体地,在本实施方式中的铰链组件应用于本申请中的扬声器装置中时,保护套管70可以与分别设置在保护套管70的长度方向上的两侧的耳挂以及机芯壳体连接在一起。在一个应用场景中,保护套管70还可以为扬声器装置中的其它结构,例如,一些部件的保护盖层等一体成型,从而使得扬声器装置更加封闭、一体。
需要指出的是,本申请实施例中的铰链组件不仅仅可以用于本申请扬声器装置实施方式中的扬声器装置,还可以用于其它装置当中,例如眼镜、耳机、助听器等。在一些实施例中,铰链组件还可以包括除了上述杆状件2540、固定件2550、连接线、保护套管70等之外的其它与铰链2530相关联的构件以实现相应的功能。
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,环状凸脊部71和环状连接部72的数量不局限于图中所示,具体数量可以根据实际使用情况而定。又例如,可以根据保护套管70的长度、环状凸脊部71和环状连接部72本身在保护套管70长度方向上的宽度等情况设定。诸如此类的变形,均在本申请的保护范围之内。
图14所示为根据本申请一些实施例所示的一种扬声器装置的结构模块图。在一些实施例中,扬声器装置1400可以至少包括耳机芯1402、辅助功能模块1404和软性电路板1406。
在一些实施例中,耳机芯1402可以接收音频电信号并将音频信号转换为声音信号。软性电路板1406为不同模块/组件之间提供电连接。例如,软性电路板1406可以提供耳机芯1402与外部控制电路和辅助功能模块1404之间的电连接。
在一些实施例中,耳机芯1402可以至少包括磁路组件、振动组件以及容纳磁路组件和振动组件的支架。磁路组件用于提供磁场,振动组件用于将输入至振动组件的电信号转化为机械振动信号,并由此产生声音。在一些实施例中,振动组件可以至少包括线圈和内部引线。在一些实施例中,耳机芯1402还包括外部导线,外部导线能够将音频电流传输至振动组件中的线圈。外部导线可以一端连接耳机芯的内部引线,一端连接扬声器装置的软性电路板。在一些实施例中,支架可以具有埋 线槽,所述外部导线和/或所述内部导线可以部分设置于所述埋线槽内,具体详见本申请其他部分的描述。
在一些实施例中,辅助功能模块1404用于接收辅助信号,执行辅助功能。辅助功能模块1404可以为区别于耳机芯之外的用于接收辅助信号而执行辅助功能的模块。在本申请中,将音频信号转换为声音信号可以认为是扬声器装置1400的主要功能,而不同于主要功能的其他功能可以认为是扬声器装置1400的辅助功能。例如,扬声器装置1400的辅助功能可以包括通过麦克风接收用户和/或环境声音,通过按键控制所述声音信号的播放过程等。其对应的辅助功能模块可以是麦克风、按键开关等,具体可根据实际需求设置。所述辅助信号可以是与辅助功能相关的电信号、光信号、声信号和振动信号中的一种或多种的组合。
扬声器装置1400还包括用于容纳所述耳机芯1402、所述辅助功能模块1404和所述软性电路板1406的机芯壳体1408。当扬声器装置1400是上述的MP3播放器时,机芯壳体1408的内壁可以和耳机芯中的振动组件直接或者间接相连接,当用户佩戴所述MP3播放器时,机芯壳体1408的外壁与用户接触并将振动组件的机械振动经由骨骼传递到听觉神经,使人体听到声音。在一些实施例中,扬声器装置可以包括耳机芯1402、辅助功能模块1404、软性电路板1406和机芯壳体1408。

在一些实施例中,扬声器装置1400通过骨传导方式传递声音。机芯壳体1408外表面可以具有贴合面。所述贴合面为当用户佩戴扬声器装置1400时,扬声器装置1400的与人体相接触的外表面。扬声器装置1400能够将贴合面压紧在预设区域(耳屏前端、头骨位置或耳廓背面),从而有效地将振动信号经由骨骼传递给用户的听觉神经,提高扬声器装置1400的音质。在一些实施例中,贴合面可以与耳廓背面贴合。机械振动信号由耳机芯传导至机芯壳体,并通过机芯壳体的贴合面传导至耳廓背面,进而由耳廓背面附近的骨骼将振动信号传至听神经。在这种情况下,耳廓背面附近骨骼更接近听神经,具有更好的传导效果,可以提高扬声器装置1400向听神经传递声音的效率。
在一些实施例中,扬声器装置1400还可以包括固定机构1410。在一些实施例中,固定机构1410可以是图2中所示的耳挂10中的一部分或整体。固定机构1410与所述机芯壳体1408外部连接,用于支撑并保持所述机芯壳体1408的位置。在一些实施例中,所述固定机构1410内可以设置有电池组件和控制电路。所述电池组件可以为扬声器装置1400中的任意电子组件提供电能。所述控制电路可以控制扬声器装置1400中的任意功能组件,所述功能组件包括但不限于耳机芯、辅助功能模块等。所述控制电路可以通过软性电路板与电池及其他功能组件连接,也可以通过导线与电池及其他功能组件连接。
图15是根据本申请一些实施例所示的机芯壳体内部的软性电路板的结构示意图。
在一些实施例中,软性电路板上可以设置多个焊盘,并通过若干不同的软性引线将不同的信号导线(例如,音频信号导线、辅助信号导线)与不同的焊盘分别电连接,以避免音频信号导线和辅助信号导线都需要与耳机芯或辅助功能模块连接,产生的内部导线众多并且繁杂的问题。如图15和图16所示,软性电路板44至少包括多个第一焊盘45和多个第二焊盘(未在图中示出)。在一些实施例中,图15中的软性电路板44与图14中软性电路板1406相对应。所述第一焊盘45中的至少一个第一焊盘45与辅助功能模块电连接,所述至少一个第一焊盘45通过所述软性电路板44上的第一软性引线47与至少一个所述第二焊盘电连接,所述至少一个第二焊盘通过外部导线(未在图中示出)与所述耳机芯(未在图中示出)电连接。所述第一焊盘45中的至少另一个第一焊盘45与辅助信号导线电连接,所述至少另一个第一焊盘45与所述辅助功能模块通过所述软性电路板44上的第二软性引线49电连接。在本实施例中,至少一个第一焊盘45与辅助功能模块电连接,至少一个第二焊盘通过外部导线和耳机芯电连接,再通过第一软性引线47将至少一个第一焊盘45中的一个与至少一个第二焊盘中的一个进行电连接,使得外部音频信号导线和辅助信号导线同时通过软性电路板与耳机芯和多个辅助功能模块电连接,简化了走线的排布。
在一些实施例中,所述音频信号导线可以是与耳机芯电连接并向耳机芯传输音频信号的导线。所述辅助信号导线可以是与辅助功能模块电连接并与辅助功能模块进行信号传输的导线。
在一些实施例中,参见图15,具体地,所述软性电路板44上设置有多个焊盘45以及两个焊盘(未在图中标出),该两个焊盘与多个焊盘45位于软性电路板44的同一侧并间隔设置。且两个焊盘通过软性电路板44上的软性引线47连接至多个焊盘45中对应的两个焊盘45上。进一步地,该机芯壳体41内还容纳有两条外部导线,每条外部导线的一端焊接在对应的焊盘上,另一端连接至耳机芯,从而使得耳机芯通过外部导线与焊盘连接。辅助功能模块可贴装于该软性电路板44上,并通过该软性电路板44上的软性引线49连接至多个焊盘45中的其它焊盘上。
在一些实施例中,扬声器装置1400的固定机构1410中设置有导线,导线至少包括音频信号导线和辅助信号导线。在一些实施例中,固定机构1410中的导线可以是多条,包括至少两条音频信号导线和至少两条辅助信号导线。例如,固定机构1410可以是耳挂10(图15中所示),耳挂与机芯壳体41连接,导线可以是设置在耳挂中的导线,多个耳挂导线的一端焊接至机芯壳体41内设置的软性电路板44上,或者控制电路板上,另一端则进入机芯壳体41内部,并与软性电路板44上的焊盘45焊接。
其中,多个耳挂导线中的两条音频信号导线的位于机芯壳体41内的一端焊接至两条软性引线47所焊接的两个焊盘45,另一端可直接或间接连接在控制电路板上,该两个焊盘45进一步通过软性引线49与两个焊盘46的焊接,以及两条外部导线与焊盘的焊接而连接耳机芯,从而向耳机芯传递音频信号。
至少两条辅助信号导线的位于机芯壳体41内的一端焊接至软性引线49所焊接的焊盘45上,另一端则可直接或间接连接在控制电路板上,从而向控制电路(未在图中示出)传递由辅助功能模块接收并转化得到的辅助信号。
上述方式中,在机芯壳体41内设置软性电路板44,并在软性电路板44上进一步设置相应的焊盘,从而将导线(未在图中示出)进入机芯壳体41内后焊接在相应的焊盘上,并进一步通过焊盘上的软性引线47、软性引线49进一步再连接相应的辅助功能模块,从而避免将多个导线均直接连接在的辅助功能模块上而使得机芯壳体41内的走线繁杂的情况,从而能够优化走线的排布,并节约机芯壳体41空间的占用;而且将多个耳挂架导线均直接连接在的辅助功能模块上时,耳挂导线的中间部位悬挂于机芯壳体41内而容易造成的振动,从而带来异响以影响耳机芯的发声质量,而按照上述方式中将耳挂导线焊接在软性电路板44上而进一步连接相应的辅助功能模块则能够减少导线悬挂而影响耳机芯发生质量的情况,从而在一定程度上能够提高耳机芯的发声质量。
在一些实施例中,可以进一步在软性电路板(或称为软性电路板44)上进行分区,将软性电路板划分成至少两个区域。每一分区上可以设置有一个辅助功能模块,以使得软性电路板上可以设置有至少两个辅助功能模块,通过软性电路板实现音频信号导线和辅助信号导线与至少两个辅助功能模块之间的走线。在一些实施例中,所述软性电路板可以至少包括主体电路板和第一分支电路板。所述第一分支电路板和所述主体电路板相连,并远离所述主体电路板沿所述主体电路板的一端延伸。辅助功能模块可以至少包括第一辅助功能模块和第二辅助功能模块。第一辅助功能模块可以设置于所述主体电路板上,第二辅助功能模块可以设置于所述第一分支电路板上。多个第一焊盘可以设置于所述主体电路板上,第二焊盘可以设置于所述第一分支电路板上。在一些实施例中,所述第一辅助功能模块可以为按键开关,所述按键开关可以设置于所述主体电路板上,并对应于按键开关设置所述第一焊盘。所述第二辅助功能模块可以为麦克风,所述麦克风设置于第一分支电路板上,并在第一分支电路板上设置有对应于麦克风的第二焊盘。通过第二软性引线连接所述主体电路板上对应于按键开关的第一焊盘与第一分支电路板上对应于麦克风的第二焊盘,可以将按键开关与麦克风进行电连接,使按键开关可以对麦克风进行控制或操作。
在一些实施例中,所述软性电路板还可以包括第二分支电路板,所述第二分支电路板和所述主体电路板相连,并远离所述主体电路板沿所述主体电路板的另一端延伸,并与所述第一分支电路板间隔设置。所述辅助功能模块还可以包括第三辅助功能模块,所述第三辅助功能模块设置在所述第二分支电路板上。所述多个第一焊盘设置于所述主体电路板上,至少一个所述第二焊盘设置于所述第一分支电路板上,其他所述第二焊盘设置与所述第二分支电路上。在一些实施例中,所述第三辅助功能模块可以是第二麦克风。第二分支电路板与主体电路板垂直延伸,第二麦克风贴装于第二分支电路板远离主体电路板的端部,多个焊盘则设置于主体电路板远离和第二分支电路板的端部。
具体地,如图15和图16所示,第二辅助功能模块可以是第一麦克风432a,第三辅助功能模块可以是第二麦克风432b。其中,第一麦克风432a和第二麦克风432b都可以是MEMS(微型机电***)麦克风432,工作电流小,性能较为稳定,且产生的语音质量高。两个麦克风432根据实际需求可设置在软性电路板44的不同位置上。
其中,软性电路板44包括主体电路板441(或称为主体电路板)以及与主体电路板441连接的分支电路板442(或称为第一分支电路板)和分支电路板443(或称为第二分支电路板),分支 电路板442与主体电路板441同向延伸,第一麦克风432a贴装于分支电路板442远离主体电路板441的端部,分支电路板443与主体电路板441垂直延伸,第二麦克风432b贴装于分支电路板443远离主体电路板441的端部,多个焊盘45则设置于主体电路板441远离分支电路板442和分支电路板443的端部。
在一些实施例中,机芯壳体41包括环绕设置的周侧壁411以及与周侧壁411的一端面连接的底端壁412,进而形成具有一开口端的容置空间。其中,耳机芯经开口端放置于容置空间内,第一麦克风432a固定于底端壁412上,第二麦克风432b固定于周侧壁411上。
在本实施例中,可以适当对分支电路板442和/或分支电路板443进行弯折,以适应麦克风432对应的入声孔在机芯壳体41上的位置的设置。具体地,软性电路板44可以主体电路板441平行于底端壁412的方式设置于机芯壳体41内,从而能够使得第一麦克风432a对应于底端壁412,而无需对主体电路板441进行弯折。而第二麦克风432b由于固定于机芯壳体41的周侧壁411上,因此需要对第二主体电路板441进行弯折设置,具体可将分支电路板443在远离主体电路板441的端部弯折设置,以使得分支电路板443的板面垂直于主体电路板441和分支电路板442的板面,并进而使得第二麦克风432b朝向背离主体电路板441和分支电路板442的方向而固定于机芯壳体41的周侧壁411上。
在一些实施例中,焊盘45、焊盘、第一麦克风432a和第二麦克风432b均可设置于软性电路板44的同一侧,焊盘与第二麦克风432b相邻设置。
其中,焊盘可具体设置于分支电路板443远离主体电路板441的端部,并与第二麦克风432b朝向相同并间隔设置,从而随分支电路板443的弯折而垂直于焊盘45的朝向。需要指出的是,分支电路板443在弯折后其板面也可以不垂直于主体电路板441的板面,具体可根据周侧壁411与底端壁412之间的设置方式而定。
进一步地,软性电路板44的另一侧设置有用于支撑焊盘45的刚性支撑板4a、麦克风刚性支撑板4b,该麦克风刚性支撑板4b包括用于支撑第一麦克风432a的刚性支撑板4b1以及用于共同支撑焊盘46与第二麦克风432b的刚性支撑板4b2。
其中,刚性支撑板4a、刚性支撑板4b1和刚性支撑板4b2主要用于对相应的焊盘和麦克风432起支撑作用,从而需具有一定的强度。三者的材质可以相同或者不同,具体可以为聚酰亚胺(PolyimideFilm,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,三个刚性支撑板的厚度可以根据刚性支撑板本身所具有的强度以及焊盘45、焊盘以及第一麦克风432a、第二麦克风432b所实际需求的强度进行设定,此处不做具体限定。
其中,刚性支撑板4a、刚性支撑板4b1和刚性支撑板4b2可以为一个刚性支撑板整体的三个不同区域,或者也可以是三个彼此间隔设置的独立的整体,此处不做具体限定。
在一些实施例中,第一麦克风432a和第二麦克风432b分别对应于两个麦克风组件(未在图中示出)。在一些实施例中,两个麦克风组件的结构相同,机芯壳体41上设置有入声孔413,进一步地,该扬声器装置在机芯壳体41处还设置有一体成型于机芯壳体41的内表面的环形挡壁414, 并设置于入声孔413的***,进而定义一与入声孔413连通的容置空间(未在图中示出)。
在一些实施例中,软性电路板44可设置于刚性支撑板(如,刚性支撑板4a、刚性支撑板4b1和刚性支撑板4b2)和麦克风432之间,并在对应于麦克风刚性支撑板4b的入声孔4b3的位置设置有入声孔444。
进一步地,软性电路板44进一步向远离麦克风432的方向延伸,以与其它功能元件或导线连接而实现相应的功能。对应地,麦克风刚性支撑板4b上也随着软性电路板向远离麦克风432的方向延伸出一段距离。
对应地,环形挡壁414上设置有与软性电路板44的形状匹配的缺口,以允许该软性电路板44从容置空间延伸而出。另外,可在该缺口处进一步填充密封胶,以进一步提高密封性。
在一些实施例中,如图17所示,软性电路板44可包括主体电路板445以及分支电路板446,其中,该分支电路板446可沿垂直于主体电路板445的延伸方向而延伸。其中多个焊盘45设置于主体电路板445远离分支电路板446的端部,按键开关贴装于主体电路板445上,焊盘46设置于分支电路板446远离主体电路板445的端部。第一辅助功能模块可以是按键开关431,第二辅助功能模块可以是麦克风432。
在本实施例中,软性电路板44的板面与底端壁412平行间隔设置,以使得按键开关可朝向机芯壳体41的底端壁412设置。
如前所述,耳机芯(或称为耳机芯1402)可以包括磁路组件、振动组件、外部导线、支架。其中,振动组件包括线圈和内部引线,外部导线能够将音频电流传输至振动组件中的线圈。外部导线可以一端连接耳机芯的内部引线,一端连接扬声器装置的软性电路板。支架可以具有埋线槽,至少部分所述外部导线和/或所述内部导线可以设置于所述埋线槽内。在一些实施例中,内部引线和外部引线彼此焊接连接,焊接位置可以位于所述埋线槽内。
具体的,参见图18和图19,耳机芯包括支架421、线圈422以及外部导线48。支架421用于对整个耳机芯结构起支撑以及保护作用。本实施方式中,支架421上设置有埋线槽4211,可用于容纳耳机芯的线路。
线圈422可设置于支架421上,并具有至少一个内部引线423,该内部引线423的一端与线圈422中的主线路连接,以将主线路引出,并通过该内部引线423向线圈422传输音频电流。
外部导线48一端与内部引线423进行连接,进一步地,该外部导线48另一端可连接至控制电路(未在图中标出),以通过控制电路而藉由内部引线423向线圈422传输音频电流。
具体地,在装配阶段,需要将外部导线48和内部引线423通过焊接等方式连接在一起,由于结构等因素的限制,在焊接完成后,不能使得线的长度与通道的长度恰好一致,通常会有多余长度的线。而多余长度的线若不能够得到合理的放置,则会随线圈422的振动而振动,从而发出异响,影响耳机芯所发出的声音质量。
进一步地,可将外部导线48和内部引线423中的至少一个卷绕设置于埋线槽4211内,在一个应用场景中,可将内部引线423和外部导线48之间的焊接位置设置于埋线槽4211内,从而将 外部导线48和内部引线423位于焊接位置附近的部分卷绕于埋线槽4211内。另外,为了保持稳定,可进一步在埋线槽4211内填充密封胶,从而对埋线槽4211中的走线起固定作用。
上述实施例中,在支架421上设置埋线槽4211,从而将外部导线48和内部引线423中的至少一个卷绕设置于埋线槽4211内,以收纳多余长度的走线,从而减弱其在通道当中所产生的振动,进而减少由于振动产生异响而对耳机芯所发出的声音质量的影响。
在一些实施例中,支架421包括环形主体4212、支撑凸缘4213以及外挡壁4214。其中,环形主体4212、支撑凸缘4213以及外挡壁4214可通过一体成型得到。
其中,环形主体4212设置于整个支架421的内侧,用于支撑线圈422。具体地,环形主体4212的沿垂直于环形径向的方向上的横截面与线圈422一致,线圈422设置于该环形主体4212的朝向机芯壳体内部一端,且该环形主体4212的内侧壁和外侧壁可分别与线圈422的内侧壁与外侧壁平齐,从而使得线圈422的内侧壁与环形主体4212的内侧壁共面设置,以及线圈422的外侧壁与环形主体4212的外侧壁共面设置。
进一步地,支撑凸缘4213凸出设置于环形主体4212的外侧壁上,并向环形主体4212的外侧延伸,具体可沿垂直于环形主体4212的外侧壁的方向向外侧延伸。其中,该支撑凸缘4213可设置于环形主体4212的两端部之间的位置。在本实施例中,该支撑凸缘4213可以环绕环形主体4212的外侧壁凸出形成一环状的支撑凸缘4213。在其它实施方式中,也可以根据需求而仅在环形主体4212的外侧壁的部分位置凸出形成。
外挡壁4214与支撑凸缘4213连接并沿环形主体4212的侧向与环形主体4212间隔设置。其中,外挡壁4214可间隔套设于环形主体4212和/或线圈422的***,具体可根据实际需求而部分套设于环形主体4212和线圈422的***,而部分套设于环形主体4212的***。需要指出的是,本实施方式中,外挡壁4214靠近埋线槽4211的部分套设于部分环形主体4212的***。具体地,外挡壁4214设置于支撑凸缘4213的远离机芯壳体的一侧。其中,环形主体4212的外侧壁与支撑凸缘4213远离机芯壳体的侧壁以及外挡壁4214的内侧壁共同定义该埋线槽4211。
在一些实施例中,环形主体4212和支撑凸缘4213上设置有走线通道424,内部引线423经走线通道424延伸至埋线槽4211内。
其中,该走线通道424包括位于环形主体4212上的子走线通道4241和位于支撑凸缘4213上的子走线通道4242。子走线通道4241贯穿环形主体4212的内侧壁和外侧壁设置,并在环形主体4212于靠近线圈422的一侧设置有连通该子走线通道4241一端的走线口42411,在靠近支撑凸缘4213的朝向机芯壳体内部一侧设置有连通该子走线通道4241另一端的走线口42412;子走线通道4242则沿朝向机芯壳体外部的方向贯通支撑凸缘4213,并在支撑凸缘4213朝向机芯壳体内部一侧设置有连通该子走线通道4242一端的走线口42421,在远离机芯壳体内部一侧设置有连通子走线通道4242另一端的走线口42422。其中,走线口42412与走线口42421通过支撑凸缘4213与环形主体4212之间的空间连通。
进一步地,内部引线423可进入走线口42411,并沿子走线通道4241延伸,并从走线口 42412穿出而进入环形主体4212与支撑凸缘4213之间的区域,进一步由走线口42421进入子走线通道4242,在由走线口42422穿出后延伸入埋线槽4211。
在一些实施例中,外挡壁4214的顶端设置有开槽42141,外部导线48可经开槽42141延伸至埋线槽4211内。
其中,外部导线48的一端设置于柔性电路板44上,该柔性电路板44具体设置于耳机芯的朝向机芯壳体内部一侧。
本实施例中,支撑凸缘4213进一步延伸至外挡壁4214的远离环形主体4212的一侧,以形成一外边缘。进一步地,该外边缘环绕抵接于机芯壳体的内侧壁。具体地,支撑凸缘4213的外边缘设置有开槽42131,从而使得位于耳机芯的朝向机芯壳体内部一侧的外部导线48能够通过该经开槽42131延伸至而由支撑凸缘4213的朝向机芯壳体外部一侧,进而延伸至开槽42141,并由开槽42141而进入埋线槽4211。
进一步地,机芯壳体内侧壁上设置有一端位于软性电路板44一侧,另一端连通开槽42131的沿朝向机芯壳体外部的方向延伸的导引槽416,以使得在外部导线48通过该导引槽416而由软性线路板延伸至第二走线槽3331。
在一些实施例中,支架421进一步包括沿环形主体4212的周向间隔设置且连接环形主体4212、支撑凸缘4213和外挡壁4214的两个侧挡壁4215,进而在两个侧挡壁4215之间定义埋线槽4211。
具体地,两个侧挡壁4215相对设置于支撑凸缘4213上,沿支撑凸缘4213朝向机芯壳体外部一侧凸出。其中,两个侧挡壁4215的朝向环形主体4212的一侧与环形主体4212的外侧壁连接,远离环形主体4212的一侧终止于外挡壁4214的外侧壁,并将走线口42422以及开槽42141限定于两个侧挡壁4215之间,从而使得由走线口42422穿出的内部引线423以及由开槽42141进入的外部导线48延伸入两个侧挡壁4215定义的埋线槽4211当中。
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,分支电路板还可以包括第三焊盘和第三软性电路板。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,所述扬声器装置可以包括一个或多个声源。所述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20显示一种通过气传导的方式传递声音的示意图。
如图20所示,声源2210和声源2220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,所述声源2210和声源2220可以是分别位于扬声器装置上特定位置(例如,机芯壳体20,或者电路壳体 30)的两个出声孔。
在一些实施例中,声源2210和声源2220可以由同一个振动装置2201产生。所述振动装置2201包括振膜(未显示在图中)。当所述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2212在出声孔处形成声源2210,振膜背面驱动空气振动,通过导声通道2222在出声孔处形成声源2220。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,或者电路壳体30)围成的路径。需要知道的是,在一些可替代的实施例中,声源2210和声源2220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2210和声源2220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2210和声源2220距离用户耳朵的位置较近,为了描述方便,所述传递到用户耳朵的声音可以称为近场声音,所述传递到环境中的漏音可以称为远场声音。在一些实施例中,所述扬声器装置产生的不同频率的近场/远场声音与声源2210和声源2220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2210和声源2220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2210和声源2220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。所述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)耳挂处的保护套管与机芯壳体弹性抵接,提高了扬声器装置的防水性能;(2)通过采用不同的模具对耳挂和机芯壳体分别成型可以减小成型模具的尺寸,从而降低了模具的加工难度以及耳挂和机芯壳体生产时的成型难度;(3)机芯壳体与耳挂之间通过铰链组件连接,可以调整机芯壳体与人体皮肤的贴合位置;(4)将外部导线和内部引线中的至少一个卷绕设置于支架上的埋线槽内,以收纳多余长度的走线,从而减弱导线在通道当中所产生的振动,进而减少由于振动产生异响而对耳机芯所发出的声音质量的影响,提高扬声器装置的音质。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“模块”、“单元”、“组件”或“***”。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,本申请所述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***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***。
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”表明所述数字允许有±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,本申请中所述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。
