Description

一种防止外放扬声器与麦克风声音串扰的方法及终端 本申请要求于 2012年 2月 29日提交中国专利局、 申请号为 201210050140.0中国专利申请的优先权,其全部内容通过引用结合在本申请 中。
技术领域 本发明涉及通信领域, 尤其涉及一种防止外放扬声器与麦克风声 音串扰的方法及终端。 背景技术 扬声器和麦克风是手机等终端设备必须的电子部件,手机等终端 通常有外放和非外放两个扬声器, 其中非外放扬声器也可称为听筒, 用于在用户进行非免提通话时将对方的声音传输给用户;外放扬声器 常用于在免提电话时将对方的声音放大播放给用户,或用于外放音乐 等需要外放声音或音频信号的场合。 麦克风用来拾取用户的声音, 并 把声音通过网络发送给对方。 在手机等终端设计过程中, 经常会遇到 外放扬声器和麦克风距离很近的情况。用户在打免提电话时由于外放 扬声器和麦克风两者距离过近,麦克风会拾取外放扬声器播放的对方 的声音并将所述对方的声音再回传给对方, 导致回声, 严重时会产生 嘯叫, 即造成外放扬声器与麦克风声音串扰。
现有技术中用于防止外放扬声器与麦克风声音串扰的方法有多 种, 目前常用的技术方案是设置外放扬声器和麦克风的安全距离; 或 者降低麦克风放大器的增益, 即减少灵敏度; 或者减小外放扬声器的 音量; 还有就是釆取特殊的电路以及软件算法消除回声。
在应用上述几种技术方案的过程中,发明人发现现有技术中至少 存在如下问题:设置外放扬声器和麦克风的安全距离实际上限制了外 放扬声器和麦克风设计的自由;降低麦克风放大器的增益或减小外放 扬声器的音量实际是人为放弃了麦克风或外放扬声器的性能,降低了 用户感受; 釆取特殊的电路以及软件算法则增加了成本以及功耗。 发明内容 本发明的实施例提供一种防止外放扬声器与麦克风声音串扰的 方法及终端,可以在满足用户体验和不增加成本的情况下有效的防止 外放扬声器与麦克风声音串扰。
为达到上述目的, 本发明的实施例釆用如下技术方案:

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,所描述的实施例仅仅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。
本发明实施例提供了一种防止扬声器与麦克风声音串扰的方法, 如图 1所示, 所述方法可以包括以下步骤:
101、 在终端接通来电后, 检测终端的免提通话功能是否开启。
102、 若所述免提通话功能开启, 则使用第一麦克风、 非外放扬 声器、第二麦克风和外放扬声器中的所述第二麦克风和所述外放扬声 器。
其中所述第一麦克风与所述外放扬声器的间距小于所述第二麦 克风与所述外放扬声器的间距。
其中, 所述 102包括, 若所述免提通话功能开启, 且所述第一麦 克风、 非外放扬声器处于开启状态, 则关闭所述第一麦克风、 非外放 扬声器, 使用所述第二麦克风和所述外放扬声器。 这种场景可以是用 户刚从非免提通话切换到免提通话, 免提通话功能刚刚开启, 非免提 通话时使用的所述第一麦克风、 非外放扬声器还没有关闭时的情况。 所述 102还包括, 若所述免提通话功能开启, 且所述第一麦克风、 非 外放扬声器处于关闭状态, 则使用所述第二麦克风和所述外放扬声 器。 即, 若所述免提通话功能开启, 则使用第一麦克风、 非外放扬声 器、 第二麦克风和外放扬声器中的所述第二麦克风和所述外放扬声 器。
用户在接到对方来电后,会根据需要选择进行免提通话或非免提 通话。 若用户选择进行免提通话, 则触发开启终端的免提通话功能, 如点击终端的免提通话功能键。此时终端会触发发起开启免提通话请 求, 终端根据所述开启免提通话请求检测到所述免提通话功能开启, 此时终端会进行打开第二麦克风、 打开外放扬声器这两个操作, 这两 个操作在一定时间间隔之内先后或同时进行, 在此不做限制。 即只使 用第一麦克风、 非外放扬声器、 第二麦克风和外放扬声器中的所述第 二麦克风和所述外放扬声器;这样使与外放扬声器间距较近的第一麦 克风处于关闭状态, 使用与外放扬声器间距较远的第二麦克风, 由于 所述第二麦克风与所述外放扬声器的间距不会造成所述外放扬声器 与所述第二麦克风的声音串扰,从而有效防止在进行免提通话时外放 扬声器与麦克风的声音串扰。
本发明实施例提供了一种防止外放扬声器与麦克风声音串扰的 方法, 通过在终端接通来电后, 检测终端的免提通话功能是否开启; 并在所述免提通话功能开启时, 使用第一麦克风、 非外放扬声器、 第 二麦克风和外放扬声器中的所述第二麦克风和所述外放扬声器;在所 述免提通话功能关闭且通话未结束时, 使用所述第一麦克风、 非外放 扬声器、第二麦克风和外放扬声器中的所述第一麦克风及所述非外放 扬声器。其中所述第一麦克风与所述外放扬声器的间距小于所述第二 麦克风与所述外放扬声器的间距,使得用户在进行免提通话时使用距 离所述外放扬声器较远的所述第二麦克风,有效的防止了外放扬声器 与麦克风的声音串扰。所述方法不用设置所述第一麦克风与所述外放 扬声器的安全距离, 从而提高了外放扬声器和麦克风设计的自由度; 也不用降低终端的麦克风以及外放扬声器的性能,从而保证了终端的 麦克风以及外放扬声器的性能, 提升了用户的体验; 也不用釆取特殊 的电路以及软件算法, 从而节省了成本及功耗。
在本发明提供的一种防止扬声器与麦克风声音串扰的方法的一 个实施例中, 如图 2所示, 所述方法除了包括步骤 101、 102外还包 括以下步骤:
103、 若所述免提通话功能关闭且通话未结束, 则使用所述第一 麦克风、 非外放扬声器、 第二麦克风和外放扬声器中的所述第一麦克 风及所述非外放扬声器。 即, 当用户在进行非免提通话时, 使用所述 第一麦克风及所述非外放扬声器。
若用户在接到对方来电后, 选择进行非免提通话, 即一般的正常 通话, 则触发开启终端的非免提通话功能, 如点击终端的非免提通话 功能键, 也即为常用的用于接听来电的通话功能键。 此时终端的免提 通话功能并未开启即为关闭状态,从而终端可以检测到所述免提通话 功能关闭,如可通过终端的开启非免提通话请求来检测到所述免提通 话功能关闭, 此时终端会打开第一麦克风和非外放扬声器, 即只使用 所述第一麦克风、 非外放扬声器、 第二麦克风和外放扬声器中的所述 第一麦克风及所述非外放扬声器, 以进行非免提通话。
若用户在进行免提通话的过程中,根据实际情况需要进行非免提 通话。此时用户可以触发开启终端的非免提通话功能或触发关闭终端 的免提通话功能, 以进入非免提通话, 如点击终端的非免提通话功能 键。此时终端会触发发起开启非免提通话请求或触发发起关闭免提通 话请求,终端可根据所述开启非免提通话请求或关闭免提通话请求检 测到所述免提通话功能关闭,此时终端会进行四个操作关闭第二麦克 风、 关闭所述外放扬声器, 打开第一麦克风、 打开非外放扬声器, 即 只使用所述第一麦克风、 非外放扬声器、 第二麦克风和外放扬声器中 的所述第一麦克风及所述非外放扬声器, 来进行非免提通话。 所述四 个操作在一定时间间隔之内先后或同时进行,但本发明实施例对于四 个操作的执行顺序并不作限制。优选的, 所述四个步骤中打开第一麦 克风在关闭外放扬声器之后, 例如可以按照关闭第二麦克风、 关闭外 放扬声器, 打开第一麦克风、 打开非外放扬声器依次进行, 也可以按 照关闭外放扬声器、 关闭第二麦克风、 打开非外放扬声器、 打开第一 麦克风等依次进行。
当然,用户在进行非免提通话的过程中也可能由于某些原因需要 进行免提通话。 此时用户会触发开启终端的免提通话功能, 如点击终 端的免提通话功能键。 此时终端会触发发起开启免提通话请求, 终端 可根据所述开启免提通话请求检测到所述免提通话功能开启,此时终 端会进行四个操作: 关闭第一麦克风、 关闭非外放扬声器、 打开第二 麦克风、 打开外放扬声器, 即只使用第一麦克风、 非外放扬声器、 第 二麦克风和外放扬声器中的所述第二麦克风和所述外放扬声器,来进 行免提通话;这样使与外放扬声器间距较近的第一麦克风处于关闭状 态, 使用与外放扬声器间距较远的第二麦克风, 由于所述第二麦克风 与所述外放扬声器的间距不会造成所述外放扬声器与所述第二麦克 风的声音串扰,从而有效防止在进行免提通话时外放扬声器与麦克风 的声音串扰, 所述麦克风包括所述第一、 第二麦克风。
上述四个操作在一定时间间隔之内先后或同时进行,但本发明实 施例对于四个操作的执行顺序并不作限制。 优选的, 所述四个步骤中 关闭第一麦克风在打开外放扬声器之前,例如可以按照关闭第一麦克 风、关闭非外放扬声器、打开第二麦克风、打开外放扬声器依次进行, 也可以按照关闭非外放扬声器、 关闭第一麦克风、 打开外放扬声器、 打开第二麦克风等依次进行。
104、 通话结束后, 使所述第一麦克风、 第二麦克风、 外放扬声 器及非外放扬声器均关闭。
步骤 104可以在步骤 102或 103之后。
具体的, 通话结束可以有如下几种场景:
一种场景是用户在进行免提通话时通话被结束,所述通话被结束 可以由用户或对方触发,即可以是用户点击或选择终端的通话结束键 结束了通话, 也可以是对方挂断了电话而结束了本次通话。 用户在进 行免提通话时使用的是第二麦克风和外放扬声器,即非外放扬声器和 第一麦克风关闭, 第二麦克风和外放扬声器开启。 故在通话结束时或 通话结束后, 需要关闭第二麦克风和外放扬声器, 从而使得在通话结 束后所述第一麦克风、 第二麦克风、 外放扬声器及非外放扬声器均关 闭。
第二种场景是用户在进行非免提通话时通话被结束,所述通话被 结束可以由用户或对方触发。用户在进行非免提通话时使用的是非外 放扬声器和第一麦克风, 即第二麦克风和外放扬声器关闭, 非外放扬 声器和第一麦克风开启。 故在通话结束时或通话结束后, 需要关闭非 外放扬声器和第一麦克风, 从而使得在通话结束后所述第一麦克风、 第二麦克风、 外放扬声器及非外放扬声器均关闭。
还有一种场景是终端接到对方来电,但由于某种原因不便接通电 话, 此时用户直接点击或选择终端的通话结束键结束通话, 由于未接 通电话故所述第一麦克风、 第二麦克风、 外放扬声器及非外放扬声器 一直处于关闭状态。
本实施例中图 2 所示的方法流程应用于用户在进行非免提通话 时通话结束及用户在进行免提通话时通话结束的场景。
本发明实施例提供了一种防止外放扬声器与麦克风声音串扰的 方法, 通过在终端接通来电后, 检测终端的免提通话功能是否开启; 并在所述免提通话功能开启时, 使用第一麦克风、 非外放扬声器、 第 二麦克风和外放扬声器中的所述第二麦克风和所述外放扬声器;在所 述免提通话功能关闭且通话未结束时, 使用所述第一麦克风、 非外放 扬声器、第二麦克风和外放扬声器中的所述第一麦克风及所述非外放 扬声器。其中所述第一麦克风与所述外放扬声器的间距小于所述第二 麦克风与所述外放扬声器的间距,使得用户在进行免提通话时使用距 离所述外放扬声器较远的所述第二麦克风,有效的防止了外放扬声器 与麦克风的声音串扰。所述方法不用设置所述第一麦克风与所述外放 扬声器的安全距离, 从而提高了外放扬声器和麦克风设计的自由度; 也不用降低终端的麦克风以及外放扬声器的性能,从而保证了终端的 麦克风以及外放扬声器的性能, 提升了用户的体验; 也不用釆取特殊 的电路以及软件算法, 从而节省了成本及功耗。
本发明实施例提供了一种终端,如图 3所示所述终端包括检测单 元 301、 控制单元 302。 检测单元 301 , 用于在终端接通来电后, 检测终端的免提通话功 能是否开启。
控制单元 302 , 用于在所述免提通话功能开启时, 使用第一麦克 风、 非外放扬声器、 第二麦克风和外放扬声器中的所述第二麦克风和 所述外放扬声器;其中所述第一麦克风与所述外放扬声器的间距小于 所述第二麦克风与所述外放扬声器的间距;以使得用户在进行免提通 话时使用所述外放扬声器和距离所述外放扬声器较远的所述第二麦 克风, 从而防止所述外放扬声器与所述第一麦克风的声音串扰。
用户在接到对方来电后,会根据需要选择进行免提通话或非免提 通话。 若用户选择进行免提通话, 则触发开启终端的免提通话功能, 如点击终端的免提通话功能键。此时终端会触发发起开启免提通话请 求,检测单元 301根据所述开启免提通话请求检测到所述免提通话功 能开启, 此时控制单元 302会进行打开第二麦克风、 打开外放扬声器 这两个操作, 这两个操作在一定时间间隔之内先后或同时进行, 在此 不做限制。 即只使用第一麦克风、 非外放扬声器、 第二麦克风和外放 扬声器中的所述第二麦克风和所述外放扬声器;这样使与外放扬声器 间距较近的第一麦克风处于关闭状态,使用与外放扬声器间距较远的 第二麦克风,由于所述第二麦克风与所述外放扬声器的间距不会造成 所述外放扬声器与所述第二麦克风的声音串扰,从而有效防止在进行 免提通话时外放扬声器与麦克风的声音串扰。
所述控制单元 302可以具体用于, 在所述免提通话功能开启, 且 所述第一麦克风、 非外放扬声器处于开启状态时, 关闭所述第一麦克 风、 非外放扬声器, 使用所述第二麦克风和所述外放扬声器。 这种场 景可以是用户刚从非免提通话切换到免提通话,免提通话功能刚刚开 启, 非免提通话时使用的所述第一麦克风、 非外放扬声器还没有关闭 时的情况。 所述控制单元 302还可以具体用于, 若所述免提通话功能 开启, 且所述第一麦克风、 非外放扬声器处于关闭状态, 则使用所述 第二麦克风和所述外放扬声器。
进一步地, 所述控制单元 302 , 还用于在所述免提通话功能关闭 且通话未结束时, 使用所述第一麦克风、 非外放扬声器、 第二麦克风 和外放扬声器中的所述第一麦克风及所述非外放扬声器;以使得所述 用户使用所述第一麦克风及所述非外放扬声器进行非免提通话。 若用户在接到对方来电后, 选择进行非免提通话, 即一般的正常 通话, 则触发开启终端的非免提通话功能, 如点击终端的非免提通话 功能键, 即常用的用于接听来电的通话功能键。 此时终端的免提通话 功能并未开启即为关闭状态,从而检测单元 301可以检测到所述免提 通话功能关闭,如可通过终端的开启非免提通话请求来检测到所述免 提通话功能关闭,此时控制单元 302会打开第一麦克风和非外放扬声 器, 即只使用所述第一麦克风、 非外放扬声器、 第二麦克风和外放扬 声器中的所述第一麦克风及所述非外放扬声器进行非免提通话。
若用户在进行免提通话的过程中,根据实际情况需要进行非免提 通话。此时用户可以触发开启终端的非免提通话功能或触发关闭终端 的免提通话功能, 以进入非免提通话, 如点击终端的非免提通话功能 键。此时终端会触发发起开启非免提通话请求或触发发起关闭免提通 话请求,检测单元 301可根据所述开启非免提通话请求或关闭免提通 话请求检测到所述免提通话功能关闭,此时控制单元 302会进行四个 操作: 关闭第二麦克风、 关闭所述外放扬声器、 打开第一麦克风、 打 开非外放扬声器, 即只使用所述第一麦克风、 非外放扬声器、 第二麦 克风和外放扬声器中的所述第一麦克风及所述非外放扬声器来进行 非免提通话。 所述四个操作在一定时间间隔之内先后或同时进行, 但 本发明实施例对于四个操作的执行顺序并不作限制。 优选的, 所述四 个步骤中打开第一麦克风在关闭外放扬声器之后,例如可以按照关闭 第二麦克风、 关闭外放扬声器, 打开第一麦克风、 打开非外放扬声器 依次进行, 也可以按照关闭外放扬声器、 关闭第二麦克风、 打开非外 放扬声器、 打开第一麦克风等依次进行。
当然,用户在进行非免提通话的过程中也可能由于某些原因需要 进行免提通话。 此时用户会触发开启终端的免提通话功能, 如点击终 端的免提通话功能键。 此时终端会触发发起开启免提通话请求,检测 单元 301 可根据所述开启免提通话请求检测到所述免提通话功能开 启, 此时控制单元 302会进行四个操作: 关闭第一麦克风、 关闭非外 放扬声器、打开第二麦克风、打开外放扬声器, 即只使用第一麦克风、 非外放扬声器、第二麦克风和外放扬声器中的所述第二麦克风和所述 外放扬声器, 来进行免提通话; 这样使与外放扬声器间距较近的第一 麦克风处于关闭状态, 使用与外放扬声器间距较远的第二麦克风, 由 于所述第二麦克风与所述外放扬声器的间距不会造成所述外放扬声 器与所述第二麦克风的声音串扰,从而有效防止在进行免提通话时外 放扬声器与麦克风的声音串扰, 所述麦克风包括所述第一、 第二麦克 风。
上述四个操作在一定时间间隔之内先后或同时进行,但本发明实 施例对于四个操作的执行顺序并不作限制。 优选的, 所述四个步骤中 关闭第一麦克风在打开外放扬声器之前,例如可以按照关闭第一麦克 风、关闭非外放扬声器、打开第二麦克风、打开外放扬声器依次进行, 也可以按照关闭非外放扬声器、 关闭第一麦克风、 打开扬声器、 打开 第二麦克风等依次进行。
进一步的, 所述控制单元 302还用于在通话结束时, 使所述第一 麦克风、 第二麦克风、 外放扬声器及非外放扬声器均关闭。
具体的, 通话结束可以有如下几种场景:
一种场景是用户在进行免提通话时触发终端的通话结束键结束 了通话。 用户在进行免提通话时使用的是第二麦克风和外放扬声器, 非外放扬声器和第一麦克风关闭, 第二麦克风和外放扬声器开启。 故 控制单元 302在通话结束时需要关闭第二麦克风和外放扬声器,从而 使得在通话结束时所述第一麦克风、 第二麦克风、 外放扬声器及非外 放扬声器均关闭。
第二种场景是用户在进行非免提通话时触发终端的通话结束键 结束了通话。用户在进行非免提通话时使用的是非外放扬声器和第一 麦克风关闭, 第二麦克风和外放扬声器关闭, 非外放扬声器和第一麦 克风开启。故控制单元 302在通话结束时需要关闭非外放扬声器和第 一麦克风, 从而使得在通话结束时所述第一麦克风、 第二麦克风、 外 放扬声器及非外放扬声器均关闭。
还有一种场景是终端接到对方来电,但由于某种原因不便接通电 话, 此时用户直接点击终端的通话结束键结束通话, 由于未接通电话 故控制单元 302需要使所述第一麦克风、 第二麦克风、 外放扬声器及 非外放扬声器一直处于关闭状态。
在本发明所提供的一个实施例中, 如图 4所示, 当所述终端为手 机时,所述第一麦克风 41和所述外放扬声器 43位于所述手机的底部, 所述第二麦克风 42及非外放扬声器 44位于所述手机的顶部。 其中, 户的声音通过通信网传输给对方, 非外放扬声器 44用于在用户进行 非免提通话时将对方的声音传输给用户; 第二麦克风 42用于在用户 进行免提通话时拾取用户的声音并将用户的声音通过通信网传输给 对方, 外放扬声器 43用于在用户进行免提通话时将对方的声音播放 给用户。 所述第一麦克风 41、 第二麦克风 42及外放扬声器 43的具 体位置可以变化, 只需保证所述第一麦克风 41与所述外放扬声器 43 的间距小于所述第二麦克风 42与所述扬声器 43的间距即可。这样在 进行免提通话时可以关闭与外放扬声器 43 间距较近的第一麦克风 41 , 使用与外放扬声器 43间距较远的的第二麦克风 42。 由于所述第 二麦克风 42与所述外放扬声器 43的间距较远,从而可有效防止外放 扬声器与麦克风的声音串扰。
需要说明的是,本发明实施例中所述的第一麦克风可以是一个麦 克风, 也可以是多个麦克风, 所述的第一麦克风为距离所述外放扬声 器很近的、会产生声音串扰的所有麦克风。 所述的第二麦克风可以是 一个麦克风, 也可以是多个麦克风, 所述的第二麦克风为距离所述外 放扬声器较远的、 不会产生声音串扰或串扰较小的所有麦克风, 所述 第一麦克风与所述外放扬声器的间距小于所述第二麦克风与所述外 放扬声器的间距。 所述麦克风的个数可根据具体情况设定, 在此不作 限制。 终端检测到免提通话功能开启时, 就会关闭所有第一麦克风, 打开任意一个或多个第二麦克风及外放扬声器;在检测到免提通话功 能关闭且通话未结束时, 终端会关闭所有第二麦克风及外放扬声器, 打开任意一个或多个第一麦克风。 还需要说明的是, 本文中所述外放 扬声器及非外放扬声器的个数可以为一个或多个。
本发明实施例提供了一种防止外放扬声器与麦克风声音串扰的 终端, 通过在终端接通来电后, 检测终端的免提通话功能是否开启; 并在所述免提通话功能开启时, 使用第一麦克风、 非外放扬声器、 第 二麦克风和外放扬声器中的所述第二麦克风和所述外放扬声器;在所 述免提通话功能关闭且通话未结束时, 使用所述第一麦克风、 非外放 扬声器、第二麦克风和外放扬声器中的所述第一麦克风及所述非外放 扬声器。其中所述第一麦克风与所述外放扬声器的间距小于所述第二 麦克风与所述外放扬声器的间距,使得用户在进行免提通话时使用距 离所述外放扬声器较远的所述第二麦克风,有效的防止了外放扬声器 与麦克风的声音串扰。所述终端不用设置所述第一麦克风与所述外放 扬声器的安全距离, 从而提高了外放扬声器和麦克风设计的自由度; 也不用降低终端的麦克风以及外放扬声器的性能,从而保证了终端的 麦克风以及外放扬声器的性能, 提升了用户的体验; 也不用釆取特殊 的电路以及软件算法, 从而节省了成本及功耗。
最后, 还需要说明的是, 在本文中, 诸如第一和第二等之类的关系术 语仅仅用来将一个实体或者操作与另一个实体或操作区分开来,而不一定 要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。
