为了解决相关技术的耳机装置不能通过旋转进行终端智能化控制的问题，本发明实施例提供了一种旋转式耳机装置及控制方法，以下结合附图以及实施例，对本发明实施例进行进一步详细说明。
本发明实施例的一种旋转式耳机装置如图2所示，包括耳机插头21、耳机座22、耳机旋转识别装置和控制装置23，所述耳机旋转识别装置分别与所述耳机座22和所述控制装置23连接，在使用时所述耳机插头21插入所述耳机座22。
以3.5mm三段式耳机为例，本实施例的耳机插头的结构如图3a～图3f所示，包括外环端(对应耳机电势参考地)、中环端(对应右声道)和芯端(对应左声道)，其中外环端为具有轴对称特性的多边形结构，即所述耳机插头具有多边形导体结构，所述外环端设置有用于检测磁场的磁化薄膜。出于保证耳机的兼容性使用的考虑，本实施例中，耳机制造标准中地导体以上部分保持不变，仅调整作为耳机电势参考地的造型结构——将传统的圆形结构，改为具有轴对称特性的多边形结构，本实施例为四方形结构，其他结构形式也可包含在内，且薄膜结构不局限于本实施例图中所示的对角线的形式，其他对称结构也可包含在内。
本实施例的耳机座的结构如图4a～图4d所示，本实施例的耳机座具有磁场腔体，当所述耳机插头插入所述耳机座并进行旋转时，所述多边形导体切割所述磁场腔体内的磁力线，产生电动势。出于保证耳机座的兼容性使用的考虑，本实施例中，耳机座制造标准中主体部分保持不变，仅增加耳机座磁场腔体(黑色实体部分)。所述磁场腔体包括电流绕线、电磁导体和磁屏蔽腔体；所述电流绕线设置为：传输系统馈入的电流；所述电磁导体在所述电流绕线有电流存在的条件下，将电流转换为磁场；所述磁屏蔽腔体设置为：阻止磁场泄露，起到保护系统减小干扰的作用。本实施例中的耳机座不局限于图中的方形电-磁转换结构，其他形状的结构形式也可包含在内，且数量也可为1。

本实施例的耳机旋转识别装置设置为：当所述耳机插头插入所述耳机座并进行旋转时，采集所述耳机插头相对于所述耳机座的旋转数据。参照图2，所述耳机旋转识别装置包括耳机识别触发单元24、数据采集单元25和信号处理单元26；所述耳机识别触发单元24通过向所述磁场腔体27供电，在所述耳机座22内建立磁场，为识别旋转操作提供必要产生和判断环境；所述数据采集单元25设置为：在所述耳机装置的初始化和所述耳机插头21旋转过程中中产生的电信号进行数据采集；所述信号处理单元26设置为：根据采集的数据，判断所述耳机插头21旋转的方向和角度，以作为所述控制装置控制受控外设28的依据。
本实施例的控制装置23与所述耳机旋转识别装置连接，设置为：根据所述旋转数据对使用所述耳机装置的终端(受控外设28)进行控制，所述对终端进行控制包括调节音频音量。
本发明实施例的一种旋转式耳机装置的电路逻辑如图6所示，其中分压放大电路、鉴幅鉴相器(即鉴幅器和鉴相器)和ADC采样电路即为图2中所示的数据采集单元的结构，所述鉴幅鉴相器分别与所述分压放大电路和ADC采样电路连接。
所述分压放大电路设置为：检测耳机初次接入和旋转过程中产生的电压弱信号，并对所述电压弱信号进行放大，得到无失真的放大信号。
转动电压的检测可通过平面二维结构简单举例，根据时变电磁场定律：
1)当耳机插入后，磁场(磁场场强B＝B0sin(ωbt))建立时，产生的感生电动势Ein＝-wB0hωbcos(ωbt)cosα，可用于初始化耳机空间位置(t＝0)。其中w表示导体平面宽度，B0表示恒定磁场场强，h表示导体平面长度，ωbt表示磁场随时间的变化量，α表示导体平面与其法向的夹角；

Ein＝B0hwωrsin2(ωbt)，可用于判断线圈旋转的角速度ωr。
本发明实施例的一种耳机旋转方向示意图如图7所示，参照图7对耳机旋转方向的识别方法进行说明，本实施例中，规定逆时针旋转时角度为负值。可见，耳机装置旋向分别为顺时针和逆时针时，磁通Φ的变化规律不同——当磁化材料法向与磁场方向平行时，磁通量最大；当磁化材料法向与磁场方向垂直时，磁通量最小。耳机初始位置的判断可根据上述初始化耳机空间位置的公式进行获取。

系统控制单元即为图2中所示的控制装置，其主要控制过程包括：
1)首先检测耳机装置接入终端设备；
2)控制分压放大电路完成上电；
3)控制电磁转换器产生稳定磁场；
4)接收DSP分析模块产生的角度信息(数字信号)；
5)通过电信号控制受控单元完成特定的操作；
6)控制系统装置的检测周期；
7)识别耳机装置拔出状态，并控制电路装置下电。
下面以利用手机的旋转式耳机装置进行耳机音频音量调节为例，对旋转式耳机装置的使用流程进行说明，其流程如图8所示。以终端为手机为例，用户在使用前将手机开机，后续的使用步骤为：首先，用户在首次使用本发明实施例的旋转式耳机装置时，耳机插入耳机接口并被终端正确识别到；然后，用户启用耳机识别功能软件，等待系统完成校准；最后，用户通过有线
耳机正常接收音频，期间可以通过旋转耳机(双向)进行耳机音量大小的调节。其过程如下：
硬件上，当用户插入耳机时，终端根据耳机座内置弹片的电信号状态首先检测耳机是否存在，若正确识别耳机装置，则系统输出稳定频率的弱电流为耳机座外侧的磁场腔体“充磁”，使之建立恒定磁场，并以此时耳机装置的回馈电压作为校准的初始(参考)状态。完成校准后，有相应的用户提示。
当用户根据不同的应用场景进行耳机旋转操作时，由于耳机的方形导体部分不断切割磁力线，因此在耳机装置的导体表面会有感应电动势(电压)幅相的连续变化，变化过程被传递给数据检测和处理电路，经过幅相分离和采样后转变为数据流，以实现实时记录。
当用户旋转操作结束后，耳机装置上的感应电动势消失，装置据判定用户操作已完成，记录并保留当前系统状态(或被系统作为中断处理)。
当用户拔出耳机后，终端正确检测出耳机状态，系统对整个装置的控制做复位处理。
其中，本发明实施例的旋转式耳机装置可以应用在以下场景：
1)用户开启终端设备，通过有线耳机进行音频、视频格式的多媒体文件播放；
2)用户开启终端设备，通过有线耳机进行电路域或分组域语音通话；
3)用户开启终端设备，通过有线耳机进行FM等无线业务的接听或发送。

可选地，上述实施例的全部或部分步骤也可以使用集成电路来实现，这些步骤可以被分别制作成一个个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。
上述实施例中的装置/功能模块/功能单元可以采用通用的计算装置来实现，它们可以集中在单个的计算装置上，也可以分布在多个计算装置所组成的网络上。
