Description

技术领域
本发明涉及移动通讯领域, 特别是涉及一种调节通话音量的方法、 装 置及移动终端。 背景技术
科学发现每个人的左右耳听力都是有差距的, 尤其是一些患过耳朵方 面疾病的人, 他们双耳听力的差距会很大。 根据 1998年国外一项听力调查 显示, 在校儿童中约有 1%的儿童单边听力损失。 在 2009年在《中华儿科 学杂志》上的调查显示, 西安市中学生听力减退患病率 2.30%。 据统计, 我 国目前有约 2780万听力障碍者, 居各类残疾人群之首。 而且受环境污染, 噪声、 频繁使用耳机听歌等影响, 听力障碍者的人数呈上升的趋势。
针对双耳听力不同的用户, 他们在接听电话时会有很多的不便。 他们 长时间通话时, 单侧接听太久会感到不适, 一般会左右耳轮流接听, 而此 时如果听筒声音保持不变的话, 用户就会觉得声音太大或太小。 当他们频 繁的左右耳交替时, 要不断的调节音量, 这样会影响其通话时的心情, 进 而对手机感到不满。 另外, 大脑的左半部分和右半部分处理声音的方式不 同, 因此, 双耳听到声音时会用不同的方式进行处理。 左耳对音乐最为敏 感, 而右耳则会更好地获取说话声。
在用户左右耳轮流通话的过程中, 由于左右耳听力不同, 用户常需要 不断的手动对听筒的音量进行调节, 导致接听电话时的多种不便。 发明内容

为了解决现有技术用户通话的过程中, 用户常需要不断的手动对听筒 的音量进行调节, 无法实现自适应的音量调节, 导致接听电话时存在多种 不便的问题, 本实施例提供了一种调节通话音量的方法、 装置及移动终端, 以下结合附图对本发明进行进一步详细说明。 应当理解, 此处所描述的具 体实施例仅仅用以解释本发明, 并不限定本发明。
本实施例提供的调节通话音量的方法的流程可以如图 1 所示, 包括步 驟 S102至步驟 S104。
步驟 S102: 在设定的检测时间到达时, 对终端的重力位置信息进行检 测。
步驟 S104: 当重力位置信息与相邻上次检测得到的重力位置信息分别 位于预设的重力零点线两侧时, 按设定的音量调节规则, 对当前的通话音 量进行调节。
其中, 重力零点线为移动终端处于竖直状态下的中分线, 重力位置信 息为移动终端重心沿重力方向所在的铅垂线。
本实施例通过检测移动终端的重力位置信息的变化, 在与上一次检测 相比时, 重力位置信息显示位于重力零点线不同两侧时, 确定移动终端在 左右耳间有交换, 则将当前的通话音量调节为另一音量。
可见, 本实施例可以自动调节通话过程中的通话音量, 提升了移动终 端的性能, 提高了用户体验, 很好地解决了现有技术在用户左右耳交替通 话的过程中, 由于左右耳听力不同, 用户常需要不断的手动对听筒的音量 进行调节, 导致接听电话时的多种不便的问题。
在检测之前, 可以对重力零点线的左右区域分别进行划分, 即左、 右 两个区域, 在检测时间到达时, 检测重力位置信息与相邻上次检测得到的 重力位置信息是否分别位于预设的重力零点线两侧。
当移动终端的重力位置信息感应到移动终端的重力由左侧区域变化到 右侧区域时, 将当前的通话音量调节为右侧区域对应的通话音量; 或者, 当移动终端的重力位置信息由右侧区域变化到左侧区域时, 则将当前的通 话音量调节为左侧区域对应的通话音量。
设置时, 可以对移动终端左侧区域和右侧区域进行赋值, 例如, 在左 侧区域时, 检测到的重力位置信息为正, 当重心由左进入右时, 重力位置 信息变成负, 则通过该方法可以简单的判断出移动终端的重心位于哪个区 域, 进而确定如何调节通话音量。 在设置时要注意, 为了显示左右区域的 不同, 可以使左侧区域和右侧区域内的值不同时为正或负, 当然, 也可以 设置一个区间, 例如左侧区域的取值范围在 [1,2] , 右侧区域的取值范围在 [2,3] , 将检测到的重力位置信息的大小进行判断, 进而确定重心位于哪个 区域, 则此时的 2为重力零点线对应的值。
在实现上述方法的过程中, 可能由于用户打电话姿势的浮动过于大, 进而引起一些误判断, 例如并没有在左右耳间进行切换, 但是通话音量却 进行了调节, 因此, 在调节通话音量之前, 判断移动终端与用户头部间的 距离是否超过了预设距离阈值, 如果超过了预设距离阈值, 再调节通话音 量。 实现过程中, 可以通过距离探测器对移动终端与用户头部的距离进行 检测, 当移动终端与用户头部的距离超过了预设距离阈值时, 移动终端的 屏幕可能会被点亮, 进一步确定的确发生了移动终端在左右耳进行了交换, 此时再调节通话音量, 避免了误操作带来的问题。
在检测移动终端的重力位置信息时, 还存在一种情况, 就是在检测的 时间点上, 重力位置信息正好处于重力零点线上, 此时, 不对移动终端进 行通话音量调节; 设定一个定时时间 T, 在 T时间到达时, 再次检测重力 位置信息。 本实施例中的 T设置为小于检测时间, 当然也可以根据需要进 行其他设定。
本实施例提供的调节通话音量的装置的结构示意可以如图 2所示, 包 括: 检测模块 10, 配置为在设定的检测时间到达时, 对终端的重力位置信 息进行检测; 音量控制模块 20, 与检测模块 10耦合, 配置为当重力位置信 息与相邻上次检测得到的重力位置信息分别位于预设的重力零点线两侧 时, 按设定的音量调节规则, 对当前的通话音量进行调节。
实现过程中, 还可以将上述装置的功能进一步细化, 以从属单元的形 式设置, 则上述装置的结构示意可以如图 3所示, 在图 2所示装置的基础 上, 音量控制模块 20包括: 第一音量控制单元 202, 配置为当重力位置信 息由左侧区域变化到右侧区域时, 将左侧区域对应的通话音量调节为右侧 区域对应的通话音量; 第二音量控制单元 204, 配置为当重力位置信息由右 侧区域变化到左侧区域时, 将右侧区域对应的通话音量调节为左侧区域对 应的通话音量。
为了进一步提高通话过程中调节音量的准确性, 避免误操作, 上述装 置还可以如图 4所示, 在图 2所示装置的基础上, 该装置还包括: 判断模 块 30, 与检测模块 10和音量控制模块 20耦合, 配置为判断相邻上次检测 时间到本次检测时间的时间段内终端与用户头部的距离是否超过预设距离 阈值; 音量控制模块 20, 配置为在超过所述预设距离阈值的情况下, 对终 端的通话音量进行调节。
上述装置在实现的过程中, 可能存在检测时间点检测到的重力位置信 息正好位于重力零点线上, 为了避免此种情况下上述装置无法调节通话音 量的问题, 还可以对上述装置进一步优化, 优化后的结构示意如图 5所示, 在图 4所示装置的基础上, 该装置还包括:
执行模块 40, 与检测模块 10耦合, 配置为当重力位置信息处于重力零 点线上时, 设定定时时间 T, 并在 T时间到达时, 重新对所述重力位置信 息进行检测, 其中, T小于所述检测时间。
上述检测模块可以由手机中的陀螺仪或重力感应器等实现; 所述判断 模块、 音量控制模块及执行模块均可以由 CPU芯片实现。
上述调节通话音量的装置可以设置在移动终端中, 例如, 将上述装置 设置在平板电脑、 手机等。 优选实施例
目前手机越来越人性化, 各种功能应用也非常丰富, 人性化的设计显 得尤为重要, 由于左耳对音乐最为敏感, 而右耳则会更好地获取说话声, 因此, 左右侧接听时, 有必要对音量加以区分。
本实施例提供的手机包括检测模块、 判断模块、 执行模块和音量控制 模块, 其在手机中的设置示意可以如图 6所示。
检测模块, 配置为接收所在手机中已有设备采集的手机的各种信息, 例如, 重力感应器、 光线感应器及屏幕亮度等采集的信息来判断如何进行 音量控制; 根据上述信息确定手机发生倾斜时, 将上述信息传输至判断模 块;
所述判断模块, 配置为判断所在手机与用户头部间的距离是否超过预 设距离阈值, 在确定手机与用户头部距离超过预设距离阈值时, 并且当确 定手机发生了左、 右耳间的位置变化时, 将处理结果传递给音量控制模块; 所述音量控制模块, 配置为根据判断模块传入的处理结果, 确定将发 生了左右耳的变动的手机的听筒音量进行调节。
上述检测模块可以由手机中的陀螺仪或重力感应器等实现; 所述判断 模块及音量控制模块均可以由 CPU芯片实现。
本优选实施例着重利用重力感应器和手机屏幕状态(例如, 屏幕亮度) 的信息, 通过对信息的处理来判断用户是左耳还是右耳接听电话, 再根据 预设模式调节听筒音量。
下面以上述利用了重力感应器和手机屏幕状态的信息来自动调节听筒 音量的手机进行说明:
所述重力感应器首先测量内部一片与压电片做成一体的重物在正交两 个方向的电压大小, 然后利用压电效应即可转换电压为分力, 根据两分力 的大小利用简单的几何知识即可判断出手机倾斜角度, 如图 7所示, 当手 机的位置处于垂直时, 其重力感应的方向向下; 如图 8所示, 当手机的位 置改变时, 其重力感应的方向会变化。 当我们在左侧接听电话时, 手机朝 左倾斜; 反之, 手机朝右倾斜。 根据手机的倾斜方向即可检测出用户是用 左耳还是右耳接听电话。
其中, 所述手机的倾斜方向的判断方法说明如下, 如图 9所示。
步驟 S902: 获取重力感应信息和屏幕状态信息。
实现时, 可以是通过手机中已存在的重力感应器和屏幕传感器来获得 感知。
该步驟获取参数的过程是在拨打或接听电话后, 获取重力位置信息、 手机贴近面部的信息等, 例如, 屏幕变黑的时间 t; 同时由检测模块读取在 该时间点 t重力感应器内一重物在两个坐标轴上分力大小 (x,y)。
步驟 S904: 检测模块对读取到的数据进行常规处理以得到可以传输的 数据。
步驟 S906: 根据处理后的重力位置信息判断手机是否发生了向左或向 右倾斜; 如果重力位置信息与相邻上次检测得到的重力位置信息分别位于 预设的重力零点线两侧时, 确定手机发生了向左或向右倾斜, 则执行步驟 S908; 如果未判断出存在向左或向右倾斜, 则执行步驟 S910。
步驟 S908: 音量控制模块根据输入控制输出音量。
步驟 S910: 按已确定的音量进行通话。
在 S906至 S910执行的过程中, 检测接收到上述数据后, 利用坐标参 数判断手机倾斜方向。 比如当 X大于零时, 设置其表示手机往右倾斜, 如 图 10所示, 则可以说明此时用户在用右耳接听电话。 反之, 若检测 X小于 零, 可以判断是左耳接听。 若 x=0, 说明此时手机是竖直状态, 调用执行模 块, 在 t+0.1s 时重新获取新的坐标进行判断, 直到判断出为止, 在未判断 出左右耳接听期间不调用音量控制模块, 以正常模式输出音量。
在判断用户是左耳还是右耳接听电话之后, 检测模块将判断结果传递 给音量控制模块, 该模块通过接收到的信息, 根据预设的模式控制听筒的 音量。 预设左右耳音量大小可以在通话设置中由用户预先进行设置, 例如 在图 11显示的通话设置中进行预先设置, 当进入通话设置后, 可以直接显 示自动听筒音量调节, 还可以在图 12所示通话设置下的菜单中的其他设置 中进入, 进而设置自动听筒音量调节。 至此, 接听电话的第一次判断已经 完成。 在一次通话过程中, 用户的姿势随时可能会变化。 为了准确的识别出 是用户主动的从一侧换到另一侧接听, 还是姿势的改变导致手机倾斜方向 的改变, 此时调用判断模块以确定手机与用户头部的距离是否超过预设距 离阈值, 在确定检测的距离超过预设距离与之后, 确定是用户主动的从一 侧换到另一侧接听, 此过程中屏幕可能会被点亮。
检测模块可以在屏幕由点亮到黑屏之后重新判断手机是否发生了向左 或向右倾斜。 这样当用户改变姿势 (比如低头)导致手机朝相反方向倾斜时, 由于手机一直在耳边, 屏幕不会被点亮, 因此不会出现误判。 而当用户主 动换到另一侧接听时, 听筒会逐渐远离面部再靠近, 在此过程中屏幕会被 点亮一次, 这样就会很大程度上减少误判的机会。
尽管为示例目的, 已经公开了本发明的优选实施例, 本领域的技术人 员将意识到各种改进、 增加和取代也是可能的, 因此, 本发明的范围应当 不限于上述实施例。
