本发明涉及音频播放领域， 尤其涉及一种播放音频的方法及装置。
背景技术
随着社会发展， 越来越多的多媒体文件在移动终端上进行播放， 在播放过 程中， 由于声道输出的音频信号方向固定， 进而如何使得播放的声音效果随移 动终端空间姿态的改变而改变成为待解决问题。 现有技术中， 移动终端使用双 扬声器播放音频信号， 一边通过左声道固定播放音频信号， 一边通过右声道固 定播放另一音频信号， 以实现立体声效果。

为了使得本领域技术人员更好的理解本发明实施例提供的技术方案， 现对 本发明又一实施例提供的一种播放音频的方法进行详细的说明。
本发明又一实施例提供的一种播放音频的方法， 用于移动终端， 所述移动 终端包括重力传感器以及 3个扬声器， 3个扬声器分别为扬声器八、 扬声器 B 以及扬声器 C, 其中， 如图 2所示， 在姿态 1的情况下， 扬声器 A位于移动终 端的左下方， 扬声器 B位于移动终端的右下方， 扬声器 C位于移动终端的右上 方。 如图 3所示， 所述播放音频的方法， 包括：
步骤 301、在移动终端进行屏幕旋转时， 获取空间姿态信息以及空间姿态变 化速率。
其中， 所述移动终端的旋转角度大于预设的旋转阈值时， 移动终端上进行 显示的屏幕就会发生旋转， 具体的， 例如
例如， 移动终端以姿态 1为参考姿态， 当移动终端以姿态 1为参考姿态发 生大于 60度旋转时， 移动终端的屏幕显示就会旋转 90度， 如图 4所示， 由姿 态 1顺时针旋转 90度， 移动终端处于姿态 2的状态时， 移动终端的屏幕显示也 会旋转 90度； 当移动终端以姿态 1为参考姿态发生大于 150度旋转时， 移动终 端的屏幕显示就会旋转 180度。 如图 5所示， 由姿态 1顺时针旋转 180度， 移 动终端处于姿态 3的状态时， 移动终端的屏幕显示也会旋转 180度； 当移动终 端以姿态 1为参考姿态发生大于 240度旋转时， 移动终端的屏幕显示就会旋转 270度。 如图 6所示， 由姿态 1顺时针旋转 270度， 移动终端处于姿态 4的状态 时， 移动终端的屏幕显示也会旋转 270度。
其中， 所述空间姿态信息为根据所述重力传感器采集到的所述移动终端的 位置信息生成的信息， 包括角度、 角加速度以及角变化速率。
步骤 302、根据所述空间姿态变化速率以及预先设置的速率阈值判断所述移 动终端空间姿态是否变化緩慢， 若所述移动终端空间姿态变化緩慢， 则执行步 骤 304, 否则执行步骤 303。
步骤 303、根据所述空间姿态信息从所述 3个扬声器中选出一对扬声器，控 制所述一对扬声器中的第一扬声器播放左声道， 所述一对扬声器中的第二扬声 器播放右声道， 除一对扬声器以外的剩余扬声器静音。
其中， 第一扬声器位于所述当前播放的视频信息的左侧， 第二扬声器位于 所述当前播放的视频信息的右侧。
例如， 如图 2和图 4所示， 当移动终端由姿态 1变化为姿态 2时， 才艮据空 间姿态信息得到扬声器 A位于移动终端的左上方， 扬声器 B位于移动终端的左 下方， 扬声器 C位于扬声器的右下方， 从中选出扬声器^ 扬声器 C为一对扬 声器， 此时， 控制扬声器 A静音， 扬声器 B播放左声道、扬声器 C播放右声道。
例如， 如图 2和图 5所示， 当移动终端由姿态 1变化为姿态 3时， 才艮据空 间姿态信息得到扬声器 A位于移动终端的右上方， 扬声器 B位于移动终端的左 上方， 扬声器 C位于扬声器的左下方， 从中选出扬声器八、 扬声器 B为一对扬 声器， 此时， 控制扬声器 C静音， 扬声器 B播放左声道、扬声器 A播放右声道。

值得说明的是， 在移动终端进行屏幕旋转时， 由于移动终端空间姿态变化 緩慢， 在姿态变化的过程中， 控制 3 个扬声器同时播放左声道和右声道， 并根 据空间姿态信息以及空间姿态变化速率控制扬声器播放左、 右声道的音量。
例如， 如图 2和图 4所示， 当移动终端由姿态 1緩曼变化为姿态 2的过程 中， 控制扬声器 A、 扬声器 B以及扬声器 C均播放左右声道， 根据扬声器 A在 移动终端由姿势 1变化为姿势 2的过程中， 控制扬声器 A中播放的左声道右声 道音量都根据空间姿态变化速率匀速减小， 扬声器 B中播放的左声道音量根据 空间姿态变化速率勾速增大、 右声道音量根据空间姿态变化速率勾速减小， 扬 声器 C中播放的左声道音量根据空间姿态变化速率匀速减小、 右声道音量根据 空间姿态变化速率匀速增大， 在音量变化过程中通过控制所述扬声器 A播放的 左右声道音量同所述扬声器 B播放的左右声道音量的叠加音量与所述扬声器 C 播放的左右声道的音量相等， 使得所述当前播放的视频信息的左右两侧的音场 强度在音量变化过程中保持相等， 最终， 当移动终端由姿态 1变化为姿态 2后， 扬声器 A中播放的左声道右声道音量减小为 0, 即扬声器 A处于静音状态， 扬 声器 B中播放的右声道音量减少为 0, 即扬声器 B播放左声道， 扬声器 C中播 放的左声道音量减小为 0, 即扬声器 C播放右声道。
例如， 如图 2和图 5所示， 当移动终端由姿态 1緩曼变化为姿态 3的过程 中， 控制扬声器 A、 扬声器 B以及扬声器 C均播放左右声道， 根据扬声器 A在 移动终端由姿势 1变化为姿势 3的过程中， 控制扬声器 A中播放的左声道音量 根据空间姿态变化速率勾速减小、 右声道音量根据空间姿态变化速率勾速增大， 扬声器 B 中播放的左声道音量根据空间姿态变化速率匀速增大、 右声道音量根 据空间姿态变化速率匀速减小， 扬声器 C中播放的左声道右声道音量都根据空 间姿态变化速率匀速减小， 在音量变化过程中通过控制所述扬声器 B播放的左 右声道音量同所述扬声器 B播放的左右声道音量的叠加音量与所述扬声器 A播 放的左右声道的音量相等， 使得所述当前播放的视频信息的左右两侧的音场强 度在音量变化过程中保持相等， 最终， 当移动终端由姿态 1 变化为姿态 3后， 扬声器 A中播放的左声道音量减小为 0, 即扬声器 A播放右声道， 扬声器 B中 播放的右声道音量减少为 0, 即扬声器 B播放左声道， 扬声器 C中播放的左声 道右声道音量减小为 0, 即扬声器 C处于静音状态。
例如， 如图 2和图 6所示， 当移动终端由姿态 1緩曼变化为姿态 4的过程 中， 控制扬声器 A、 扬声器 B以及扬声器 C均播放左右声道， 根据扬声器 A在 移动终端由姿势 1变化为姿势 4的过程中， 控制扬声器 A中播放的左声道音量 根据空间姿态变化速率勾速减小、 右声道音量根据空间姿态变化速率勾速增大， 扬声器 B 中播放的左声道右声道音量都根据空间姿态变化速率匀速减小， 扬声 器 C中播放的左声道音量根据空间姿态变化速率匀速增大、 右声道音量根据空 间姿态变化速率匀速减小， 在音量变化过程中通过控制所述扬声器 A播放的左 右声道音量同所述扬声器 B播放的左右声道音量的叠加音量与所述扬声器 C播 放的左右声道的音量相等， 使得所述当前播放的视频信息的左右两侧的音场强 度在音量变化过程中保持相等， 最终， 当移动终端由姿态 1 变化为姿态 4后， 扬声器 A中播放的左声道音量减小为 0, 即扬声器 A播放右声道， 扬声器 B中 播放的左声道右声道音量减小为 0, 即扬声器 B处于静音状态， 扬声器 C中播 放的右声道音量减少为 0, 即扬声器 C播放左声道。
