技术领域
本发明实施例涉及便携式收听设备技术领域，特别是涉及一种耳机及其佩戴检测装置。
背景技术
随着科技的发展，耳机在人们生活中的使用越来越普遍，其中，蓝牙耳机越来越普及，双耳无线耳机也逐渐兴起，并且集成度越来越高、体积越来越小。为了实现更长久的续航时间和更好的用户交互体验，这类耳机通常会配备佩戴检测功能。
目前，佩戴检测功能通常是通过红外、激光或电容式检测等方式实现的，不管哪种方式都需要额外的占用相当大的空间，其中，采用红外检测还会影响外观设计，电容式检测需要设置触摸感应面板，并且通过检测芯片检测触摸感应面板获取的感应信号，但是，电容式检测中的触摸感应面板通常需要额外的空间进行设置，不利于耳机的小型化，又由于耳机的内部空间有限，所以触摸感应面板的感应面积会受限，检测灵敏度受限。
鉴于此，如何提供一种解决上述技术问题的耳机及其佩戴检测装置成为本领域技术人员需要解决的问题。
发明内容
本发明实施例的目的是提供一种耳机及其佩戴检测装置，在使用过程中不仅有利于耳机的小型化，而且还能够提升佩戴状态检测灵敏度和可靠性。
为解决上述技术问题，本发明实施例提供了一种耳机的佩戴检测装置，包括：
用于构成电池封装金属外壳的感应面板、输入端与所述感应面板连接的检测芯片以及与所述检测芯片的输出端连接的控制芯片，所述电池设置于耳机的耳柄中；其中：

可选的，所述隔离层为泡棉制作而成的隔离层。
可选的，所述检测极耳与设置于所述电池的电池电芯上的正负极耳位于所述感应面板的同一个侧面上。

本发明实施例还提供了一种耳机，包括耳柄、设置于所述耳柄中的电池以及如上述所述的耳机的佩戴检测装置。
可选的，所述耳机为无线蓝牙耳机。
本发明实施例提供了一种耳机及其佩戴检测装置，包括：用于构成电池封装金属外壳的感应面板、输入端与感应面板连接的检测芯片以及与检测芯片的输出端连接的控制芯片，电池设置于耳机的耳柄中；其中，检测芯片，用于检测感应面板的感应信号，并依据感应信号确定耳机的佩戴状态；控制芯片，用于依据佩戴状态对耳机的工作状态进行调节。
可见，本申请中的检测芯片与设置于耳机耳柄内部的电池的封装金属外壳连接，将电池的封装金属外壳复用为感应面板，在用户佩戴耳机时，耳机耳柄与用户皮肤接触，感应面板和用户皮肤之间形成电容效应、产生感应信号，所以检测芯片就能够通过检测感应面板的感应信号来确定耳机的佩戴状态，以便控制芯片根据该佩戴状态对耳机的工作状态进行调节。本申请中将电池的封装金属外壳复用为感应面板，不需要额外增设感应面板，不仅节约了空间，有利于耳机的小型化，而且电池的表面面积较大，还有利于提升佩戴状态检测灵敏度和可靠性。
附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对现有技术和实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
本发明实施例提供了一种耳机及其佩戴检测装置，在使用过程中不仅有利于耳机的小型化，而且还能够提升佩戴状态检测灵敏度和可靠性。
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参照图1，图1为本发明实施例提供的一种耳机的佩戴检测装置的结构示意图。该佩戴检测装置，包括：
用于构成电池封装金属外壳的感应面板1、输入端与感应面板1连接的检测芯片2以及与检测芯片2的输出端连接的控制芯片3，电池设置于耳机的耳柄中；其中：
检测芯片2，用于检测感应面板1的感应信号，并依据感应信号确定耳机的佩戴状态；
控制芯片3，用于依据佩戴状态对耳机的工作状态进行调节。
需要说明的是，本申请中的佩戴检测装置适用于电池设置于耳柄内部的耳机，并且电池可以紧贴耳柄的外壳进行安装，电池包括电池电芯4、封装该电池电芯4的封装金属外壳以及电池保护板5，本申请中将电池的封装金属外壳作为电容式感应检测的感应面板1，也即，将检测芯片2的输入端直接与感应面板1连接，请参照图2所示的电路原理图，在用户佩戴该耳机时，耳机耳柄的外壳与用户皮肤接触，使设置在耳柄内部的感应面板1与用户皮肤之间形成电容感应，产生感应信号，检测芯片2在检测到该感应信号后，根据预先设置的分析算法对该感应信号进行分析，从而能够确定出耳机当前的佩戴状态，例如为正常佩戴状态、非正常佩戴状态或非佩戴状态等，检测芯片2在确定出耳机的当前佩戴状态后，将佩戴状态发生至控制芯片3，控制芯片3依据该佩戴状态对耳机的工作状态进行调节，例如当耳机处于正常佩戴状态时，控制耳机正常工作，当耳机处于非佩戴状态时，则控制耳机关闭或进入低功耗模式。
具体的，在用户摘下耳机的过程中，检测芯片2会检测到感应面板1产生的感应信号的感应值迅速减少，可以以此来判断耳机被摘下，如果用户将耳机放在手中，手的皮肤与耳柄上对应感应面板1的位置接触，此时感应信号的感应值比佩戴时的感应值要大，所以此时可以确定为非佩戴状态，其他的状态也可以通过检测到的感应值与正常佩戴时的感应值进行比较以及可以通过相应的算法来确保检测的准确性。另外，对于本申请中的检测芯片2具体是如何根据感应信号确定出耳机的佩戴状态的过程、以及控制芯片3具体如何依据佩戴状态对耳机的工作状态进行调节的过程还可以参照现有技术中的相应方法，本申请对此不做详述。
本申请中将耳机电池的封装金属外壳复用为电容式感应检测的感应面板1，不需要在耳机内部额外增设感应区域和空间，大大利用了现有的空间，不会增加耳机的体积、对产 品的外观设计无任何影响，并且电池的表面面积较大，也即感应面板1的表面积较大，所以还可以确保感应面板具有较大的感应面积，以提升检测的灵敏度和可靠性。
进一步的，感应面板1上设有检测极耳，电池的电池保护板上设有与检测极耳对应的检测接口，检测芯片2的输入端通过检测接口与检测极耳连接，以使检测芯片2与感应面板1连接。
具体的，耳机电池的电池电芯4上设有正负极耳，也即设有正极耳41和负极耳42(如图3所示)，本申请的感应面板1上设有检测极耳11，也即从感应面板1上引入另一个管脚作为检测极耳11(如图4所示)；对应的电池保护板5上除了设置有与正极耳41和负极耳42分别对应的正电极51和负电极52之外，还设有检测接口53(如图5所示)，正极耳41、负极耳42以及检测极耳11分别与电池保护板5上的正电极51、负电极52和检测接口53的一端连接(具体可以采用焊接的方式连接)，其中，检测接口53可以作为检测芯片2的感应检测电极，也即，检测芯片2可以通过电池保护板5上的检测接口53与感应面板1连接(如图6所示)，从而使检测芯片2能够检测到感应面板1的感应信号。
更进一步的，感应面板1中用于在耳机佩戴时通过耳柄的外壳与用户皮肤接触的面为贴合面，感应面板1中除贴合面之外的其他各面的外侧均设有隔离层。
需要说明的是，本申请中的感应面板1具有多个表面，用户在摘下耳机或拿起耳机时，手的触摸可能会使感应面板1的感应信号产生一定的影响，从而如引起误触，所以为了减少误触的发生，可以在感应面板1的各个非贴合面的外侧设置隔离层，其中，在耳机佩戴时感应面板1中的能够通过耳柄的外壳与用户皮肤接触的一面作为贴合面，其他的面作为非贴合面，在感应面板1的非贴合面的外侧设置隔离层后，用户在摘下或拿起耳机时，手与耳柄的接触面对应的为感应面板1中设有隔离层的几个面，从而能够大大降低对感应电容值的影响。
更进一步的，为了在确保隔离效果的基础上，节约成本，本实施例中的隔离层可以为泡棉制作而成的隔离层。当然，也可以采用其他材质制作而成的隔离层，具体可以根据实际需要进行确定，本申请对此不做特殊限定。
为了进一步节约空间，提高空间利用率，本实施例中的检测极耳11与设置于电池的电池电芯4上的正负极耳位于感应面板1的同一个侧面上，具体请参照图4。其中，检测极耳11可以设置于正极耳41和负极耳42的中间位置处，相应的电池保护板5上的检测接口53也设置于正电极51与负电极52的中间，与检测极耳11对应设置。
另外，本申请中的感应面板1可以为基于铝塑膜制作而成的面板，也即电池的封装金属外壳可以为铝塑膜外壳，当然，感应面板1也可以为采用其他材质制作而成的感应面板，具体可以根据实际需要进行设定，本申请对此不做特殊限定，能够实现本实施例的目的即可。
可见，本申请中的检测芯片与设置于耳机耳柄内部的电池的封装金属外壳连接，将电池的封装金属外壳复用为感应面板，在用户佩戴耳机时，耳机耳柄与用户皮肤接触，感应 面板和用户皮肤之间形成电容效应、产生感应信号，所以检测芯片就能够通过检测感应面板的感应信号来确定耳机的佩戴状态，以便控制芯片根据该佩戴状态对耳机的工作状态进行调节。本申请中将电池的封装金属外壳感应面板复用为感应面板，不仅节约了空间，有利于耳机的小型化，而且电池的表面面积较大，还有利于提升佩戴状态检测灵敏度和可靠性。
在上述实施例的基础上，本发明实施例还提供了一种耳机，包括耳柄、设置于耳柄中的电池以及如上述的耳机的佩戴检测装置。
进一步的，本实施例中的耳机为无线蓝牙耳机。具体可以为双耳无线耳柄式蓝牙耳机或单耳无线蓝牙耳机，当然，也可以为其他形式的耳机，具体不做特殊限定。
需要说明的是，本发明实施例中所提供的耳机具有与上述实施例中的耳机的佩戴检测装置相同的有益效果，并且对于本实施例中所涉及到的耳机的佩戴检测装置的具体介绍请参照上述实施例，本申请在此不再赘述。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
