技术领域
本发明涉及通信技术领域，尤其涉及一种音频播放装置、音频播放方法及电子设备。
背景技术
随着多媒体技术的发展，电子设备具备双扬声器，利用双扬声器播放音频，不仅在音量上有所提升，还能形成立体声场。
现有技术中，双扬声器需要搭载两个智能功放，一个用于驱动传统扬声器，一个用于驱动二合一扬声器。其中，二合一扬声器包括扬声器模式和受话器模式两种工作模式。当二合一扬声器处于扬声器模式时，所需要的音量大，二合一扬声器对应的智能功放的输出电压高，通路上的电流较大；当二合一扬声器处于受话器模式时，无需过大音量，该智能功放的输出电压低，通路的电流较小。
由于二合一扬声器位置靠近天线辐射位置，易受天线信号的干扰。当二合一扬声器处于扬声器模式时，对应的智能功放输出的是脉冲宽度调制(Pulse width modulation，PWM)波，此时升压高，对射频接收性能影响较大；当二合一扬声器处于受话器模式时，在全球移动通信系统(Global System for Mobile Communications，GSM)通话场景下，天线辐射也容易对音频通路产生干扰。
可见，现有技术中，二合一扬声器和射频模块同时工作时，存在相互干扰的问题。

图7是本发明实施例提供的电子设备的结构图之二。
具体实施方式
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作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。
参见图1，图1是本发明实施例提供的音频播放装置的结构图，如图1所示，音频播放装置包括：
功放模块11；
开关12，所述开关12的输入端与所述功放模块11连接；
第一噪声抑制组件13和第二噪声抑制组件14，所述第一噪声抑制组件13的第一端与所述开关12的第一输出端连接，所述第二噪声抑制组件14的第一端与所述开关12的第二输出端连接；
扬声器模块15，连接所述第一噪声抑制组件13的第二端和所述第二噪声抑制组件14的第二端，所述扬声器模块15具有受话器模式和扬声器模式；
其中，在所述扬声器模块15处于受话器模式的情况下，所述开关12的输入端与所述开关12的第一输出端连接，且所述第一噪声抑制组件13的工作参数与所述功放模块11的第一输出电流相匹配；
在所述扬声器模块15处于扬声器模式的情况下，所述开关12的输入端与所述开关12的第二输出端连接，且所述第二噪声抑制组件14的工作参数与所述功放模块11的第二输出电流相匹配。
其中，开关12包括一个输入端和两个输出端，开关12的输入端可以和第一输出端或者第二输出端连接。扬声器模块15可以是现有技术中的二合一 扬声器，其既能够用于立体声播放，即扬声器模式，也能够在手持通话的时候发声，即受话器模式。
当扬声器模块15处于受话器模式下工作时，可以将开关12的输入端和第一输出端连接，具体可以通过手动操作的方式控制或者通过电子设备智能控制连接。此时，功放模块11、第一噪声抑制组件13和扬声器模块15形成通路。在受话器模式下无需过大的音量，所以此时功放模块11的输出电压较低，输出通路上的过流较小。第一噪声抑制组件13的主要作用在于抑制GSM时分双工(Time Division Distortion，TDD)电流音干扰，第一噪声抑制组件13的工作参数可以选择与当前通路上的过流匹配的工作参数，也就是说，第一噪声抑制组件的工作参数的抑制电流音的效果较好，而过流能力能够满足输出通路的电流要求。第一噪声抑制组件可以是磁珠、电感或者是其他用于抑制噪声的器件，第一噪声抑制组件的工作参数例如，900MHz的阻抗在1kΩ以上，过流能力在0.6A以上。
当扬声器模块15处于扬声器模式下工作时，可以将开关12的输入端与第二输出端连接，具体可以通过手动操作的方式控制或者通过电子设备智能控制连接。此时，功放模块11、第二噪声抑制组件14和扬声器模块15形成通路。在扬声器模式下需要音量较大，此时功放模块11升压，输出电压较高，输出通路上的电流较大。此时对TDD电流音的干扰要求相对较低，因为用户不会在扬声器模式下耳朵贴近扬声器，第二噪声抑制组件14的工作参数可以选择与当前通路上的过流参数匹配，第二噪声抑制组件的过流能力能够满足输出通路的电流要求。第二噪声抑制组件也可以是磁珠、电感或者是其他用于抑制噪声的器件，第一噪声抑制组件和第二噪声抑制组件可以是相同或不同类型的器件。第二噪声抑制组件的工作参数例如，过流能力大于1.5A，900MHz阻抗为100Ω左右。
这样，当扬声器模块15处于受话器模式和扬声器模式时，可以分别使用第一噪声抑制组件13和第二噪声抑制组件14，既能兼顾受话器模式的抗TDD电流音的要求，也能兼顾扬声器模式对过流能力的要求。
可选的，所述第一噪声抑制组件13的阻抗大于或等于预设阻抗值，且过流能力小于预设电流值；
所述第二噪声抑制组件14的阻抗小于所述预设阻抗值，且过流能力大于或等于所述预设电流值。
在该实施方式中，由于受话器模式下无需过大的音量，功放模块11的输出电压较低，输出通路上的过流较小。第一噪声抑制组件13的主要作用在于抑制GSM TDD干扰，可以选择阻抗较大且过流能力较小的噪声抑制组件，且第一噪声抑制组件的过流能力能够满足输出通路上的过流大小。
在扬声器模式下，功放模块11的输出电压较高，输出通路上的过流较大。第二噪声抑制组件14的过流能力较大，且阻抗值较低，且第二噪声抑制组件的过流能力能够满足输出通路上的过流要求。
噪声抑制组件的具体选用参数值可以根据扬声器模块所处工作模式下的电路上的工作参数以及实际需求确定。
由于第一噪声抑制组件13和第二噪声抑制组件14的工作参数不同，在扬声器模块15处于不同工作模式下，不同的噪声抑制组件能够满足不同工作模式的需求，能够提高噪声抑制组件功能的效果。
可选的，如图2所示，所述第一噪声抑制组件13包括第一子噪声抑制组件131和第二子噪声抑制组件132，所述第一子噪声抑制组件131的第一端连接所述开关12的第一输出端，所述第一子噪声抑制组件131的第二端连接所述扬声器模块15的正极，所述第二子噪声抑制组件132的第一端连接所述开关12的输入端，所述第二子噪声抑制组件132的第二端连接所述扬声器模块15的负极。
在该实施方式中，第一噪声抑制组件13的电路图可以参照图2所示。
当图2中所示噪声抑制组件为第一噪声抑制组件13时，第一噪声抑制组件13可以包括第一子噪声抑制组件131和第二子噪声抑制组件132，第一子噪声抑制组件131和第二子噪声抑制组件132分别连接扬声器模块的正极和负极，第一子噪声抑制组件和第二子噪声抑制组件的具体连接方式可以参照现有技术。
在该实施方式中，可以通过控制开关的输入端与输出端的连接，实现功放模块与第一噪声抑制组件的连接。由于第一噪声抑制组件包括第一子噪声抑制组件和第二子噪声抑制组件，当功放模块通过开关连接第一噪声抑制组 件时，能够在第一子噪声抑制组件和第二子噪声抑制组件之间形成电流通路，且能够提高抗电流音干扰能效果。
可选的，所述第二噪声抑制组件14包括第三子噪声抑制组件和第四子噪声抑制组件，所述第三子噪声抑制组件的第一端连接所述开关12的第二输出端，所述第三子噪声抑制组件的第二端连接所述扬声器模块15的正极，所述第四子噪声抑制组件的第一端连接所述开关12的输入端，所述第四子噪声抑制组件的第二端连接所述扬声器模块15的负极。
在该实施方式中，第二噪声抑制组件14的电路图也可以参照图2所示。当图2中所示噪声抑制组件为第二噪声抑制组件14时，则第一噪声抑制组件13可以替换成第二噪声抑制组件14，第一子噪声抑制组件131和第二子噪声抑制组件132可以分别替换为第三子噪声抑制组件和第四子噪声抑制组件，第三子噪声抑制组件和第四子噪声抑制组件分别连接扬声器模块的正极和负极，第三子噪声抑制组件和第四子噪声抑制组件的具体连接方式可以参照现有技术。
在该实施方式中，可以通过控制开关的输入端与输出端的连接，实现功放模块与第二噪声抑制组件的连接。由于第二噪声抑制组件包括第三子噪声抑制组件和第四子噪声抑制组件，当功放模块通过开关连接第二噪声抑制组件时，能够在第三子噪声抑制组件和第四子噪声抑制组件之间形成电流通路，能够提升扬声器的效果。
可选的，当上述音频播放装置中的扬声器模块为二合一扬声器时，如图3所示，所述装置还包括智能功放17和普通扬声器18，所述智能功放17的输入端连接所述处理器16，所述智能功放17的输出端连接所述普通扬声器18；
所述处理器16还用于控制所述智能功放17向所述普通扬声器18输出电压，以使所述智能功放17驱动所述普通扬声器18工作。
在该实施方式中，音频播放装置包括普通扬声器18和智能功放17，其中，普通扬声器18可以是用于实现普通扬声器功能的模块。智能功放17和普通扬声器18之间可以增加第三噪声抑制组件19，以滤除智能功放输出通路与射频天线的互扰。其中，第三噪声抑制组件的电路连接方式也可以参见 图2所示。处理器16可以控制智能功放17向普通扬声器18输出电压，以普通扬声器工作。
这样，处理器16可以根据用户操作控制扬声器模块15，如即二合一扬声器，或普通扬声器18工作，从而启动不同的工作模式。
本发明实施例还提供一种电子设备，该电子设备包括上述任一实施方式中的音频播放装置，该电子设备具备上述任一实施方式中的有益效果。
可选的，所述电子设备包括处理器16，所述处理器16连接所述开关12；所述处理器16用于：
在所述扬声器模块15处于受话器模式的情况下，控制所述开关12的输入端连接所述开关12的第一输出端；
在所述扬声器模块15处于扬声器模式的情况下，控制所述开关12的输入端连接所述开关12的第二输出端。
在该实施方式中，处理器16连接开关12，处理器16可以检测扬声器模块15所处的工作模式，从而根据工作模式自动控制开关12的输入端与输出端之间的连接。处理器16与开关12的连接电路图可以参见图1。
具体地，当处理器16检测扬声器模块15处于受话器模式的情况下，处理器16控制开关12的输入端与第一输出端连接，从而使功放模块11连接第一噪声抑制组件13，第一噪声抑制组件13的工作参数与功放模块11的输出通路上的参数匹配，主要用于抑制噪音干扰，能够提高扬声器模块的效果。
当处理器16检测扬声器模块15处于扬声器模式的情况下，处理器16控制开关12的输入端与第二输出端连接，从而使功放模块11连接第二噪声抑制组件14。第二噪声抑制组件14的工作参数与功放模块11的输出通路上的参数匹配，能够提高扬声器模块的效果。
这样，处理器16可以根据扬声器模块的工作模式控制开关12选择噪声抑制组件，能够提高扬声器模块的效果。
参见图4，图4是本发明实施例提供的一种音频播放方法的流程图，该方法应用于电子设备，该电子设备包括上述实施方式中的音频播放装置。音频播放方法包括：
步骤401、接收第一输入。
用户可以根据实际需求对电子设备进行操作，即进行第一输入。第一输入可以是在显示屏上的操作或者是对物理按键的操作，或者是语音输入，等等，此处不作限定。第一输入可以是工作模式的切换操作或者是初始对工作模式的启动操作，还可以是对扬声器模块的启动操作。
步骤402、响应于所述第一输入，将所述扬声器模块切换至受话器模式，并将所述开关的输入端与所述第一输出端连接。

在此步骤中，电子设备响应第一输入，可以获取扬声器模块开启的工作模式或者第一输入所选择的工作模式。在扬声器模块切换至受话器模式的情况下，电子设备可以控制开关的输入端连接开关的第一输出端，从而使功放模块连接第一噪声抑制组件。由于第一噪声抑制组件的工作参数与当前模式下的通路上的电流参数匹配，且第一噪声抑制组件的参数能够更好地抑制TDD电流音的干扰，提高扬声器模块的效果。
步骤403、响应于所述第一输入，将所述扬声器模块切换至扬声器模式，并将所述开关的输入端与所述第二输出端连接。
