随着手机等移动互联网终端以及网络音视频软件的广泛应用，人与人之间可以越来越方便的实现随时随地的通话。目前耳机的应用非常广泛，多数情况下，人们会通过耳机来通话和听音乐等。鉴于通话环境的复杂性和多样性，人们在进行通话时也就越来越多地可能处于噪声环境之下，通话环境中的噪声对于通话质量的负面影响日益明显。比如在喧闹的街道、房间和广场中，又或者在汽车、火车等交通工具中，周围背景噪声对于通话双方的通话质量的负面影响有时会非常严重。而对于佩带耳机聆听音乐、观赏电影或进行电玩游戏的便携多媒体数码设备使用者，噪声对于用户的使用体验的负面影响则会更加让人无法忍受。因此，目前的耳机装置在将麦克风采集的音频信号发送至对端设备之前，或者播放音频信号之前，都需要进行相应的音频处理，以改变或改善音频信号质量和声音效果。如图12所示，相关技术的耳机装置中设置有音频处理单元，其包括待发送音频处理模组和待播放音频处理模组。待发送音频处理模组用于执行所有发送前的音频信号处理，并向耳机装置的通信单元输出待发送的音频信号，通信单元将该待发送的音频信号传输给通话对方；待播放音频处理模组用于执行所有播放前的音频信号处理，并向耳机装置的扬声器输出待播放的音频信号，扬声器播放该待播放的音频信号。如在用户语音通话时，利用待发送音频处理模组，对麦克风采集的包 含本地环境声音和用户语音信号的音频信号进行模数转换、数字降噪等音频处理后获得待发送的音频信号，再将其通过通信单元发送给通话对方；而对通过通信单元接收到的来自通话对方的音频信号，则利用待播放音频处理模组，进行数模转换、功率放大等处理后获得待播放的音频信号，再将其通过扬声器播放。可见，待发送音频处理模组输出到通信单元的音频信号，是在待发送音频处理模组内完成了所有发送前的音频处理的信号，通信单元及相关的编码单元只需根据预定的传输协议将其编码并传输出去；待播放音频处理模组输出到扬声器的音频信号，是在待播放音频处理模组内完成了所有播放前的音频处理的信号，扬声器只需接收该信号并播放。另外，耳机装置还会利用主动降噪处理模块，实现耳机噪声消除等。随着时间的推移，降噪技术飞速发展，特别是一些新兴科技应用在降噪领域后，耳机降噪不仅性能大幅度提升，还能够实现精准降噪、选择性降噪等多种功能，用户及其通话对方可以享受到高纯度、高智能化的视听环境。
但与此同时，用户也陷入了戴上耳机后难以听到自己的说话声音的窘境。另外由于受到使用环境、佩戴方式、设备性能以及音频处理技术设计等多方面的影响，很多耳机的音频处理的效果不尽如人意，特别是容易出现在某些时候效果好，某些时候效果差的不稳定性。在人们不希望通话的对方听到自己所处的环境声音时，人们不能确定对方是否可以听到，这使得用户对自己的耳机音频处理效果缺乏信心，例如人们在不希望通话对方听到自己所处的环境声音时，即使耳机的产品说明书上标明其具有降噪功能，甚至宣称其因采用了高智能的降噪技术可以将不需要的背景声音完全消除，人们因为不能确信而依然习惯在接听电话时用手遮挡麦克风、甚至离开所处环境。
因此，有必要提出一种改进的技术方案来解决上述问题。

实施例1
根据本公开的一些实施例，提供了一种耳机装置，其主要包括主控单元、麦克风、音频处理单元、扬声器及通信单元，其中，
所述音频处理单元，包括待发送音频处理模组和待播放音频处理模组，所述待发送音频处理模组接收麦克风采集的音频信号，并分别向所述通信单 元和所述待播放音频处理模组输出第一音频信号；所述待播放音频处理模组接收所述第一音频信号，并向所述扬声器输出第二音频信号；所述待发送音频处理模组用于对所述麦克风采集的音频信号进行发送前的音频信号处理；所述待播放音频处理模组用于对输入的音频信号进行播放前的音频信号处理。
所述主控单元，用于在检测到来自外部设备的通话请求后，检测是否播放本地音频，检测是否允许通话；
在允许播放本地音频和/或允许通话时，控制所述麦克风采集包含本地环境声音在内的本地音频信号，所述待发送音频处理模组对所述本地音频信号进行待发送音频信号处理以输出第一音频信号；
在允许播放本地音频时，控制所述待播放音频处理模组对所述第一音频信号进行待播放音频信号处理以输出第二音频信号，控制所述扬声器播放所述第二音频信号，
在允许通话时，控制所述通信单元将所述第一音频信号传输至外部设备。
进一步的，所述主控单元检测到来自外部设备的通话请求后，可以先检测是否允许接听，再检测是否播放本地音频和是否允许通话；或者，可以先检测是否播放本地音频，再检测是否允许接听及通话。
进一步的，所述的检测是否播放本地音频和是否允许通话，是先检测是否播放本地音频，在允许播放时控制所述扬声器播放所述第二音频信号，直至检测到播放本地音频的时间达到预定时长或检测到停止播放本地音频的指令；在检测到不允许播放本地音频或停止播放所述第二音频信号时，再检测是否允许通话。
所述耳机装置可以是已知的或未来的入耳式耳机、头戴式耳机、无线耳机、有线耳机、骨传导耳机、智能眼镜、智能配饰等各种支持语音通话的便携式音频采集及输出设备。
所述外部设备可以是在通话时与耳机装置建立有线或无线信号传输链接，以向耳机装置转发来自通话对方发出的通话请求、音频信息的手机、电脑、平板电脑、对讲机等电子通信设备。
所述外部设备还可以是通话对方用于通话的远端设备，如手机、电脑、平板电脑、对讲机等电子通信设备。
在本耳机装置中，由于扬声器播放的音频信号，是将麦克风采集的本地音频信号经过待发送音频处理过程后获得的，而通话过程中发送给远端设备的音频信号，也是经过该待发送音频处理过程后获得的，二者所经历的音频处理过程完全相同，从而最大程度地保证了用户从扬声器听到的声音效果与通话对方听到的声音效果的接近度。因此，不论待发送音频处理过程包括哪些具体的音频处理方式，获得哪些音频处理后的效果，用户都可以通过扬声器，检查最终发给对方的声音效果，确认当前的声音效果是否是自己想要的效果。显然这可以大大增强用户使用耳机的信心，改善体验感。
进一步的，用户检查声音效果的过程可以在通话之前，如在收到通话请求，耳机还在提示来电时，先检查声音效果，再允许接听及通话，检查声音效果的过程在接通电话之前完成，这样完全不影响与对方的通话；或者在收到通话请求后，先允许接听电话以听到对端声音，用户再视情况选择检查声音效果，之后再允许通话，这样，电话被第一时间接听，而用户检查声音效果的过程不影响对方说话，对方不会有明显不适感。可见，本公开既便于用户使用，又不影响通话质量，可在对方基本无感的情况下，完成检测声音效果的过程。
作为一种较佳实施例，图1示出本公开第一种实施例中的耳机装置100，其中：

步骤200，检测收到来自外部设备的通话请求时，进入步骤201；
步骤201，检测是否允许接听；
允许接听或拒绝接听的指令可以由用户操作耳机装置上的输入单元，或者操作与耳机装置相连的手机等移动通信设备来给出。
在允许接听来电时，进入步骤202，并同时执行步骤211，否则继续等待允许接听指令。作为一种较佳实施方式，如果一直没有收到允许接听的指令，则可以等到超过预定时长后，自动执行挂机操作，结束通话。
在接到拒绝接听的指令后，则跳转至步骤220，执行挂机操作，结束通话。
步骤202，检测是否允许播放本地音频，在允许播放本地音频时，进入步骤203，否则跳转至步骤208；
作为一种较佳实施方式，在允许播放本地音频时，还可以同时执行步骤203和205。
步骤203，采集包含本地环境声音在内的本地音频信号，对所述本地音频信号执行待发送音频处理步骤，以获得第一音频信号；
所述待发送音频处理步骤用于对所输入的音频信号进行模数转换A/D、数字降噪、双麦克风降噪、音效处理等一种或多种音频信号处理，以改善或改变所输入的音频信号的声音效果。
步骤204，对所述第一音频信号执行待播放音频处理步骤，以获得第二音频信号，并播放所述第二音频信号；
所述待播放音频处理步骤用于对所输入的音频信号进行数模转换、功率放大、音量调节等一种或多种音频信号处理，以获得适于扬声器播放的音频信号。
步骤205，向外部设备发送预设的第五音频信号；
作为一种可选的方式，为了尽量减少通话对方因为用户没有及时参与通话的不适感，在用户选择播放本地音频时，将一组预定的第五音频信号发送给通话对方，比如预定的人工语音“您好，请不要挂机,您拨打的电话正在通话中”，由此保证通话对方的通话舒适度，因此更增添了用户对本公开的通话 过程的良好体验感；
步骤206，检测播放本地音频的时间是否达到预定时长，或者是否收到停止播放本地音频的指令；
当检测到播放时间已达到预定时长，或接受到用户发出的停止播放指令后，进入步骤207，并停止播放本地音频；否则返回步骤203，继续采集本地音频信号，并播放所述第二音频信号。
所述预定时长可以设置为3s、5s等短暂的时间，既使用户有足够时间收听本地音频，也使通话对方不感觉到等待太久。
步骤207，检测是否允许通话；
当检测到用户输入的允许通话指令时，进入步骤208，而当用户选择不允许通话时，进入步骤220。
作为一种可替代的方式，本步骤中亦可以被省略，即当检测到播放时间已达到预定时长，或接受到用户发出的停止播放指令后，默认为允许通话，而直接进入步骤208。
步骤208，停止发送所述第五音频信号；
步骤209，采集包含本地环境声音在内的本地音频信号，对所述本地音频信号执行待发送音频处理步骤，以获得第一音频信号；
步骤210，向外部设备发送所述第一音频信号。
如此，用户完成了在正常通话之前试听本地音频的声音效果，而进入到与通话对端正常的通话状态中。
步骤211，接收来自外部设备的第三音频信号；
所述的第三音频信号可以是通话对方发出的语音等音频信号。
步骤212，对所述第三音频信号执行待播放音频处理步骤，以获得第四音频信号；
步骤213，播放所述第四音频信号；
由于步骤204和步骤213分别播放两路音频信号，一种实施方式是，待播放音频处理步骤还可以包括合成处理过程，即将待播放的第二音频信号和第四音频信号合成为一路音频信号，通过扬声器播放。在合成时，可以控制其中一路音频信号的音量小于另一路音频信号，从而突出用户当前想要听的 那一路音频信号，例如，使得第二音频信号的音量大于第四音频信号，以便于用户收听麦克风采集的经过待发送音频处理后的本地音频。在步骤206停止播放第二音频信号后，再恢复播放第四音频信号的音量。另一种更佳的实施方式是，扬声器包括左声道扬声器和右声道扬声器，通过其中的一个声道的扬声器播放一路音频信号，通过其中的另一个播放另一路音频信号，这样，用户从两个声道分别听到来源不同的声音，既可以清晰收听通话对方的声音，又不影响收听麦克风采集的本地音频。在步骤206停止播放第二音频信号，再恢复两个声道的扬声器播放第四音频信号。
步骤220，通话结束，挂机。
基于本实施例的通话方法，用户在收到来电请求后，可以先允许接听电话。这时，用户可以一边听着来电对方的声音，一边在选择允许播放本地音频后，自己说一段话，并通过扬声器播放来试听声音效果，比如已经滤除了环境声音、已经添加背景声音、已经改变了自己的语调、已经由男声变成女声等等。用户在确认该声音效果是自己想要的效果之后再启动通话功能，与通话对方进行正常的通话。
而对于通话对方而言，他听到通话被接听后开始说话。但由于此时用户没有允许通话，他听不到用户发出的真实声音，如果用户预先设置了第五音频信号，他此时可以听到第五音频信号，如果没有设置，他此时听不到用户传来的任何声音。直到用户允许通话后，通话对方才能听到对端传来的第一音频信号，即用户发出并经过待发送音频处理过的音频信号。而如果用户最终选择不允许通话而挂机，通话对方因为电话是在被接听后才挂断的，往往会以为是通信信号故障，而不会因为电话被挂断而心生误解和埋怨。
可见本实施例提供了一种全新的通话方法，一方面在通话过程中增加了预先确认通话的声音效果的功能，避免了隐私泄露的担忧，或无奈变换通话环境甚至挂机的尴尬，改善了隐私保护能力，提高了用户的使用信心；另一方面改变了被邀请通话方一键同时允许接听和通话的传统方式，为用户在决定与对方正常通话之前留出了确认和决策的时间，提高了通话过程中的舒适度，更有助于用户维护良好的人际交往。
实施例3
作为一种较佳实施例，图3示出本公开的第三种实施例中的通话方法。显然，该方法也可以用于实施例1中的耳机装置，其中：
步骤300，检测收到来自外部设备的通话请求时，进入步骤301；
步骤301，检测是否允许接听来电；
在允许接听来电时，执行步骤310、320和330，否则继续等待允许接听指令。作为一种较佳实施方式，如果一直没有收到允许接听的指令，则可以等到超过预定时长后，自动执行挂机操作，结束通话。
在接到拒绝接听的指令后，则跳转至步骤340，执行挂机操作，结束通话。
步骤310，检测是否允许播放本地音频，在允许播放本地音频时，进入步骤311，否则跳转至步骤314；
步骤311，采集包含本地环境声音在内的本地音频信号，对所述本地音频信号执行待发送音频处理步骤，以获得第一音频信号；
所述待发送音频处理步骤用于对所输入的音频信号进行模数转换A/D、数字降噪、双麦克风降噪、音效处理等一种或多种音频信号处理，以改善或改变所输入的音频信号的声音效果。
步骤312，对所述第一音频信号执行待播放音频处理步骤，以获得第二音频信号，并播放所述第二音频信号；
所述待播放音频处理步骤用于对所输入的音频信号进行数模转换、功率放大、音量调节等一种或多种音频信号处理，以获得适于扬声器播放的音频信号。
步骤313，检测播放本地音频的时间是否达到预定时长，或者是否收到停止播放本地音频的指令；
当检测到播放时间已达到预定时长，或接受到用户发出的停止播放指令后，进入步骤314，从而停止播放本地音频；否则返回步骤311，继续采集本地音频信号，并播放所述第二音频信号。
步骤314，停止播放本地音频；
步骤320，检测是否允许通话；
当检测到用户输入的允许通话指令时，进入步骤321，而当用户选择不允许通话时，进入步骤340，结束通话。
当未检测用户输入的是否允许通话的指令时，在一种较佳实施例中，可以等待预定时长，以便用户有足够的时间选择是否允许通话。进一步的作为一种更优实施方案，在等待用户输入是否允许通话的指令的预定时长内，可以参照实施例2的方法，向外部设备发送预设的第五音频信号，直至检测到用户输入的是否允许通话的指令。
应当可以理解的是，为了便于描述，步骤310和步骤320被分成两个检测步骤，但在具体实施时，其实质可以为一个检测步骤，即用户给出一次指令，即可表示同时选择允许或拒绝播放本音频和通话。
步骤321，采集包含本地环境声音在内的本地音频信号，对所述本地音频信号执行待发送音频处理步骤，以获得第一音频信号；
应当能理解，在同时播放本地音频和发送第一音频信号时，步骤321和步骤311可以是同一个步骤。即该步骤获得的第一音频信号可以同时用于步骤312和322。
步骤322，向外部设备发送所述第一音频信号；
步骤330，接收来自外部设备的第三音频信号；
步骤331，对所述第三音频信号执行待播放音频处理步骤，以获得第四音频信号；
步骤332，播放所述第四音频信号；
步骤340，通话结束，挂机。
基于本实施例的通话方法，用户在收到来电请求后，可以先允许接听电话，再同时允许通话和播放本地音频。这时，用户可以一边与对方正常通话，一边从扬声器中听到自己发送给对方的声音。此时，用户既可以确认通话时的声音效果，还可以在通话过程中，随时调整自己的本地声音效果，例如，发现噪声太大时，调整耳机的佩戴方式，以避免双麦克风降噪功能失效，或改变身处环境，以规避环境噪声太复杂，耳机降噪不理想；或者在通话时，随时启动变声处理，增加背景音等，与通话对方共享欢乐时刻。
可见本实施例提供的通话方法，不仅可随时发现通话声音效果的缺陷， 还可为语音通话过程增添许多乐趣。
作为实施例3的另一种变形，步骤301和步骤310、320亦可合并为一个步骤，即同时检测是否允许接听及通话，如果允许，即认为也允许播放本地音频，进而同步执行步骤311、321和330，并且步骤311和321可以合并为一个步骤。如此，则与相关技术中的一键接听电话相似，且同时还开启了播放本地音频功能。用户在无需顾忌隐私的情况下，使用更加方便。
实施例4
作为一种较佳实施例，图4示出本公开的第四种实施例中的通话方法。显然，该方法可以用于实施例1中的耳机装置，其中：
步骤400，检测收到来自外部设备的通话请求时，进入步骤401；
步骤401，检测是否允许播放本地音频，在允许播放本地音频时，进入步骤402，否则跳转至步骤405；
步骤402，采集包含本地环境声音在内的本地音频信号，对所述本地音频信号执行待发送音频处理步骤，以获得第一音频信号；
步骤403，对所述第一音频信号执行待播放音频处理步骤，以获得第二音频信号，并播放所述第二音频信号；
步骤404，检测播放本地音频的时间是否达到预定时长，或者是否收到停止播放本地音频的指令；
当检测到播放时间已达到预定时长，或接受到用户发出的停止播放指令后，进入步骤405，从而停止播放本地音频；否则返回步骤401，继续采集本地音频信号，并播放所述第二音频信号。
步骤405，检测是否允许接听及通话；
在允许接听及通话时，执行步骤406和408；在接到拒绝接听的指令后，则跳转至步骤411，执行挂机操作，结束通话。
步骤406，采集包含本地环境声音在内的本地音频信号，对所述本地音频信号执行待发送音频处理步骤，以获得第一音频信号；
步骤407，向外部设备发送所述第一音频信号；
步骤408，接收来自外部设备的第三音频信号；
所述的第三音频信号可以是通话对方发出的语音等音频信号。
步骤409，对所述第三音频信号执行待播放音频处理步骤，以获得第四音频信号；
步骤410，播放所述第四音频信号；
步骤411，通话结束，挂机。
基于本实施例提供的通话方法，用户在收到来电通话请求后，可以先允许播放本地音频，以检测通话的声音效果，在确认声音效果理想时，再允许正常通话。与实施例2和实施例3不同的是，本实施例中的步骤405与相关技术中的一键接听电话的功能相似，同时启动接听和通话功能。相对实施例2和实施例3，本实施例将用户确认通话声音效果的过程设置于来电振铃阶段，既留给用户足够的检查、调整通话声音效果的时间，也不会给通话对方带来任何影响。用户操作简单，使用方便，隐私保护性能好。
实施例5
作为一种较佳实施例，图5示出本公开第五种实施例中的耳机装置500，其中相对实施例1中的耳机装置100，差别在于耳机装置500的音频处理单元仅包括待发送音频处理模组和待播放音频处理模组。并且待发送音频处理模组仅对输入的音频信号进行模数转换和数字降噪处理。因此相对耳机装置100，其音频处理过程相对简单。但很显然本实施例的耳机装置500依然可以用于实现实施例2、3、4中的通话方法。
采用本公开上述实施例中的耳机装置和通话方法，可以在耳机装置中播放与通话对方收听的声音效果最接近的音频信号，以便用户及时、准确确认或调整通话，既保护用户隐私，又使得耳机使用更加便利、舒适。

所述通话装置600可被用于手机、平板电脑、电话机、通话手表、蓝牙耳机等各种可支持语音通话的电子设备中，从而实现本公开的可进行本地声音效果检查的通话流程。
实施例7
本实施例提供一种通话系统，包括耳机装置710和通话设备700。
其中，如图7所示，所述通话设备700与通话对端720和耳机装置710通信，用于接收来自通话对端720的通话请求，并在通话过程中，将来自通话对端720的第三音频信号转发至所述耳机装置710，将来自所述耳机装置710的第一音频信号转发至通话对端720。
所述通话设备700可以是基于电话交换通信网络接收通话对端的通话请 求，也可以是通过互联网、局域网、短距离无线通信网络等计算机通信网络接收通话对端的通话请求。所述通话请求可以是来电呼叫，亦可是通过安装在所述通话设备700内的具有语音通话功能的应用程序(application，APP)产生的语音通话请求。
在一些实施方式中，所述通话设备700可以是固定电话、移动电话、智能手机、平板电脑、个人计算机、手持式计算机、PDA等各种可实现语音通话的电子设备。具体实施时，所述通话设备700可以包括一个或多个处理器和存储器，所述存储器存储被配置为由所述一个或多个处理器执行的一个或多个程序，所述一个或多个程序包括用于实现本公开所述的通话方法的程序指令。所述通话设备700还可以以硬件、软件或硬件与软件两者的组合来实现，包括一个或多个信号处理电路和/或专用集成电路。
所述通信设备700还包括通信单元，以使得所述耳机装置710可以与所述通话设备700建立有线方式或无线方式的通信连接；还使得所述通信设备700可以与所述通话对端720建立通信连接。所述通信单元可以是一组被分时复用的无线通信电路，也可以是两组独立的通信电路，分别与耳机装置710和通话设备700通信。所述通信单元或通信电路可以采用相关技术或未来适用的技术实现，本公开对此不做具体限定。
所述耳机装置710的具体组成和结构可以与本公开实施例1或实施例6描述的相同或相似，此处不再赘述。
在一些具体实施方式中，所述通话设备700在收到通话对端720的通话请求时，向所述耳机装置710发送来电提醒信号。所述耳机装置710接收到来电提醒信号时，可通过产生振动或播放音乐、振铃、语音等多种方式提醒用户，在此不做具体限定。
所述通话设备700还用于接收用户输入的控制指令，并将所述控制指令发送给所述耳机装置710。所述控制指令可以包括允许接听、允许通话、允许或停止播放本地音频、允许接通电话(或称：允许接听及通话)、挂机等指令中的一种或多种。所述通话设备700可通过机械键盘、按钮、鼠标、具有触敏功能的触敏显示屏(或称触摸屏)、语音识别等多种方式接收用户在所述 通话设备700上输入的控制指令。在一些实施方式中，所述通话设备700还可接收所述耳机装置710发送的用户在所述耳机装置710上输入的前述控制指令。
所述通话设备700响应于允许接听指令，接收来自通话对端720的第三音频信号并向耳机装置710转发。
所述通话设备700响应于允许通话指令，接收来自耳机装置710的第一音频信号，并向通话对端720转发。
所述通话设备700响应于允许接通电话指令，接收来自通话对端的第三音频信号，并转发至耳机装置710；并接收来自耳机装置710的第一音频信号，并向通话对端转发。
所述通话设备700在未被允许通话时，响应于允许播放本地音频指令，进入用户检查声音效果状态。在所述用户检查声音效果状态下，通话设备700不向通话对端发送音频信号，或者向通话对端发送预置铃声，如可以接收耳机装置710发送的第五音频信号并作为预置铃声向通话对端转发；或者可以将预先存储在通话设备700内部的预置铃声发送至通话对端。从而可以减少通话对方因没有及时收听到用户的通话音频而引起的不适感。在一些具体实施方式中，所述通话设备700还响应于停止播放本地音频指令，停止向通话对端发送所述预置铃声。
在一些具体实施方式中，所述通话设备700还响应于挂机指令，结束与通话对端的通话过程。
应当可以理解的是，所述通话设备700在接收通话对端720或耳机装置710的音频信号后，可根据其内部预置音频处理流程或通信协议，对所接收到的音频信号进行处理或编码后再发送出去。本公开对该预置的音频处理流程或通信协议不做具体限定。
在一些具体实施方式中，所述通话设备700具有用于显示通话界面的显示器。所述通话界面至少用于显示是否允许播放本地音频的使能表示。所述通话设备700在所述通话界面接收表示选择是否允许播放本地音频的用户输入，并在未被允许通话时响应于表示允许播放本地音频的选择的用户输入，进入用户检查声音效果状态。在所述用户检查声音效果状态下，所述通话设 备700不向通话对端发送音频信号，或者仅向所述通话对端发送预置铃声。而此时，所述耳机装置710因接收到被允许播放本地音频的指令，开始采集包含本地环境声音在内的本地音频信号，对所述本地音频信号执行待发送音频处理，以获得第一音频信号；对所述第一音频信号执行待播放音频处理步骤，以获得第二音频信号，并播放所述第二音频信号。
在一些实施方式中，所述通话界面还用于显示是否允许接听的使能表示、是否允许通话的使能表示、是否允许接听及通话的使能表示、是否允许挂机的使能表示中的一种或多种。
在一些实施方式中，所述通话界面有一个或多个。
作为一种具体实施方式，所述显示器可以是具有触敏功能的触敏显示屏(或称触摸屏)。用户通过触摸显示屏，在所述通话界面触发所述使能表示，从而输入所选择的控制指令。
在一些其它的实施方式中，所述通信设备700上还设置有键盘、按键、语音识别单元、手势识别、面部识别等一种或多种形式的输入模组，以使得用户可在通话界面采用现有或未来适用的各种输入方式触发所述使能表示而输入所选择的控制指令。可以理解的是，所述使能表示还可以因接收到用户在耳机装置710上输入的控制指令而被触发。
本公开还提供一种通话设备的通话方法，参考图9及图8A～8C所示，具体包括：
步骤900，通话设备收到通话对端的通话请求，在其显示器上显示第一通话界面(如图8A所示界面800)；
其中，在所述显示器上显示的第一通话界面800至少包括显示是否允许接听的使能表示，例如图8A中图标803所示。
所述第一通话界面还可以包括是否挂机的选择使能表示，例如图标802所示。在一些具体实施方式中，可以在一个或多个通话界面上显示所述是否挂机的选择使能表示，以便用户可随时选择不接听电话，例如在确认将发送给通话对端的声音效果不是自己想要的效果，认为当前不适合接通电话时，用户可以随时选择挂机。
所述第一通话界面还可以显示来电提醒信息，如来电号码、来电联系人信息、接听状态信息等。
在一些具体实施方式中，所述通话设备700可以向耳机装置710发送来电提醒或转发通话请求，以通知耳机装置710收到通话请求。
步骤901，通话设备在第一通话界面等待接收用户输入；
通话设备可以接收用户在通话设备上输入的用户输入，也可以接收耳机装置转发的用户输入。
用户可以通过操作通话设备而触发相应的使能表示以输入表示其选择的用户输入，也可以通过操作耳机装置输入控制指令，而使得通话界面上的相应的使能表示被认为触发，从而使得通话设备接收到表示用户选择的用户输入。
步骤902，通话设备在所述第一通话界面接收表示允许接听的选择的第一用户输入，以及响应于所述第一用户输入，显示第二通话界面；
所述第二通话界面(如图8B所示界面810)至少包括显示是否允许播放本地音频的选择使能表示，还可以包括显示是否允许通话的选择使能表示。
图8B中图标804表示允许播放本地音频，图标805表示允许通话；显然，在其它实施方式中，可以将二者合并为一个图标，而通过选择顺序或连续输入次数来区分不同的使能指令，如第一次用户输入表示允许播放本地音频，第二次用户输入表示停止播放本地音频并允许通话等。亦可采用更多数量和形式的图标表示上述使能表示。诸如此类的各种变化或替换，都应涵盖在本公开的保护范围之内。
当所述通话设备响应的所述第一用户输入为用户在通话设备上输入时，所述通话设备还向耳机装置710发送允许接听指令。
所述通话设备700还响应于所述第一用户输入，允许接听来电。即，与通话对端建立语音通话连接，并接收来自通话对端的第三音频信号，将其转发至耳机装置710。但此时所述通话设备700不向所述通话对端发送音频信号，避免通话对端听到本地声音。
步骤903，通话设备在所述第二通话界面等待接收用户输入；
步骤904，通话设备在所述第二通话界面接收表示允许播放本地音频的 选择的第二用户输入，以及响应于所述第二用户输入，进入用户检查声音效果状态；
在所述用户检查声音效果状态下，所述通话设备不向通话对端发送音频信号，或者仅向所述通话对端发送预置铃声，如前述实施例中所转发的第五音频信号。并且，所述通话设备在第二通话界面继续等待接收用户输入，并根据用户输入指令，保持或退出所述用户检查声音效果状态。所述通话设备还可以根据所述耳机装置的控制指令退出所述用户检查声音效果状态，如耳机装置计时到播放时间达到预定时长时，可向所述耳机装置发送退出指令。
当所述通话设备响应的所述第二用户输入为用户在通话设备上输入时，所述通话设备还向耳机装置710发送允许播放本地音频指令，以使得所述耳机装置710可播放本地音频，帮助用户检查声音效果，即，耳机装置710获取包含本地环境声音在内的本地音频信号，并执行待发送音频信号处理后获得第一音频信号，将所述第一音频信号执行待播放音频处理后获得第二音频信号，通过扬声器播放所述第二音频信号，从而使用户可检查将被发送给通话对端的第一音频信号的声音效果。
步骤905，通话设备在所述第二通话界面接收表示允许通话的选择的第三用户输入，以及响应于所述第三用户输入，显示第三通话界面。
所述第三通话界面(如图8C所示界面820)用于显示用户与通话对端正常通话的状态，其中可包括是否挂机的选择使能表示、通话状态提醒信息、来电联系人信息、通话持续时间等与当前通话相关的信息。在一些具体实施方式中，所述第三通话界面还可以包括显示是否允许播放本地音频的选择使能表示，以随时为用户提供检查当前声音效果的功能。
响应于所述第三用户输入，所述通话设备700还接收来自耳机装置710的第一音频信号，并向通话对端720转发；同时继续接收来自通话对端720的第三音频信号，并向所述耳机装置710转发，从而实现正常的双向通话。
在一些具体实施方式中，所述是否允许通话的选择使能表示还可用于停止播放本地音频，响应于所述第三用户输入，所述通话设备700在允许通话的同时，还停止发送所述预置铃声。
步骤906，结束通话。
本步骤可以在前述任意一个通话界面下，因为接收到表示挂机的选择的用户输入，并响应于该用户输入，而执行本步骤以结束通话，亦可因通话对端主动结束通话而进入本步骤。
本实施例提供的通话设备的通话方法，改变了传统的通话界面和通话方式，将接听电话和允许通话分成两个指令使能，可更有利于用户在接通电话之前做出更稳妥的决策。
可以理解的是，所述通话设备700参照图8A～图8B所示的通话界面执行图9所示的通话方法流程时，所述耳机装置710可以参照图2所示的通话方法流程执行，此处不再赘述。
图10A～10C所示为本公开通话设备的另一种通话方法的实施方式。其中，在第四通话界面(如图10A所示界面1010，其可与界面800相同)接收到表述允许接听的选择的用户输入后，进入第五通话界面(如图10B所示界面1020)，并将来自通话对端的第三音频信号转发至耳机装置。所述第五通话界面至少包括显示是否允许播放本地音频及通话的选择使能表示。在第五通话界面下接收到表示允许播放本地音频及通话的选择的用户输入后，进入第六通话界面(如图10C所示的界面1030)。在所述第六通话界面下，所述通话设备700进入正常通话状态，即继续接收来自通话对端的第三音频信号并转发至耳机装置，同时接收来自耳机装置的第一音频信号并转发给通话对端。但此时，耳机装置710还将所述第一音频信号执行待播放音频处理后通过扬声器播放。所述第六通话界面还可显示是否允许停止播放本地音频的选择使能表示，用于在正常通过状态下，随时接收用户输入的停止本地音频播放的控制指令。可以理解的是，对应于本实施方式，所述耳机装置710可以参照图3所示的通话方法流程执行，此处不再赘述。
图11A～11C所示为本公开通话设备的通话方法的第三种实施方式。其中：
所述通话设备收到通话对端的通话请求时，在其显示器上显示第七通话界面(如图11A所示界面1110)。
所述第七通话界面1110至少包括显示是否允许接听及通话的选择使能表示，例如图11A中的图标1102所示，还包括显示是否允许播放本地音频的选择使能表示，例如图11A中的图标1101所示。
所述通话设备在第七通话界面1110接收到表示允许播放本地音频的选择的用户输入后，显示第八通话界面(如图11B所示的界面1120)，并进入用户检查声音效果状态。在用户检查声音效果状态下，所述通话设备不接听来电，即不接收通话对端的音频信号且不向通话对端发送音频信号。所述耳机装置710则播放基于所述第一音频信号获得的第二音频信号。
所述通话设备在第七通话界面1110接收到表示允许接听及通话的选择的用户输入后，显示第九通话界面(如图11C所示的界面1130，其可以与图8C所示界面820相同或相似)，并进入与通话对端的正常通话状态，即，接收来自耳机装置710的第一音频信号，并向通话对端720转发；同时接收来自通话对端720的第三音频信号，并向所述耳机装置710转发，从而实现正常的双向通话。
所述第八通话界面1120可以包括显示是否允许接听及通话的选择使能表示，还可包括指示当前处于用户检查声音效果状态的提示信息、与当前来电相关的信息等。在所述第二通话界面1120下接收到表示允许接听及通话的选择的用户输入后，所述通话设备退出用户检查声音效果状态，并显示第九通话界面1130，进入与通话对端的正常通话状态。
与前述实施方式类似的是，在本实施方式的任一通话界面上均可包括显示是否挂机的选择使能表示，以便随时接收用户输入的挂机指令，结束当前通话。
作为一种可选实施方式，所述通话设备亦可根据耳机装置发送的退出指令退出用户检查声音效果状态；所述通话设备还可以在退出用户检查声音效果状态的同时自动进入与通话对端的正常通话状态，而无需用户指令。
可以理解的是，所述的通话界面可以是指显示屏上显示的全部界面，也可以是其中包含的部分界面。所述通话界面之间的切换，可以是全部界面的切换，也可以是部分界面的切换，还可以是各使能表示的切换。所有基于本公开思想所作出的替换或修改，均在本公开的保护范围之内。
可以理解的是，对应于本实施方式，所述耳机装置710可以参照图4所示的流程实现通话，此处不再赘述。
本公开的实施例还提供一种非易失性计算机可读存储介质，包括程序，当所述程序被至少一个处理器运行时，使得所述至少一个处理器执行以下一个或多个操作：
