现通过具体实施方式结合附图的方式对本发明做出进一步的诠释说 明。
图 1 为本发明第一实施例提供的放音响度调整方法的示意图, 由图 1 可知, 在本实施例中, 本发明提供的放音响度调整方法包括以下步骤: S101 : 终端获取环境声音信号及内部声音信号;
本发明实施例中所涉及的终端, 是指可以进行放音并接收外部声音信 号的设备, 包括但不局限于手机、 电脑、 掌上电脑等, 优选的, 可以是手 机等移动终端; 本发明实施例中所涉及的环境声音信号, 是指终端所处环 境的所有声音信号, 在发明实施例中, 按照其效果将其分为两部分: 噪声 信号及放音回音信号; 其中, 放音回音信号是指终端利用麦克风采集到的 其自身通过扬声器等放音装置所放音的回音信号 , 主要包括扬声器发出的 声音通过直射以及外部环境的反射之后由麦克风接收到的声音信号, 噪声 信号是指终端利用麦克风接收到的所有声音信号中除去放音回音信号的部 分; 本发明实施例中所涉及的内部声音信号, 是指终端需要通过扬声器进 行放音的声音信号, 也即没有进行功率放大之前的声音信号; 本发明实施 例中所涉及的放音, 包括但不局限于终端播放音乐歌曲、 终端进行电话通 信或视音频通信等操作时, 扬声器所发出的声音;
S102: 根据环境声音信号及内部声音信号获取放音响度差值; 本申请所涉及的放音响度差值, 主要是指终端内部的内部声音信号的 响度值与放音回音信号的响度值之差;
当终端所处的外部环境中没有噪声或噪声可以忽略不计时, 可以直接 将环境声音信号的响度值作为放音回音信号的响度值;
当终端所处的外部环境中的噪声不可以忽略不计时, 就需要将噪声信 号进行滤除, 以得到纯粹的放音回音信号, 进而进行放音响度差值的计算; 那么, 此时, 根据环境声音信号及内部声音信号获取放音响度差值的步骤 包括: 滤除环境声音信号中的噪声信号, 得到放音回音信号; 根据放音回 音信号的响度值及内部声音信号的响度值获取放音响度差值;
优选的, 在滤除环境声音信号中的噪声信号之前还包括: 确定环境声 音信号中的噪声信号的步骤; 滤除环境声音信号中的噪声信号具体为: 将 环境声音信号中确定的噪声信号滤除;
优选的, 确定噪声信号的步骤包括: 根据声音信号相关性, 将环境声 音信号中与内部声音信号相关的信号部分滤除, 得到并输出噪声信号; 声 音信号相关性包括声音信号的波形相关性, 如声音信号的振幅、 频率及相 位等;
本申请所涉及的放音响度差值还可以是终端内部的内部声音信号的响 度值与环境声音信号中主声音信号的响度值之差; 具体的: 获取环境声音 信号的各声音信号的响度值, 将响度值最大的声音信号作为主声音信号; 根据主声音信号的响度值及放音内部信号的响度值获取放音响度差值;
S 103 : 终端比较放音响度差值与至少一个调整阈值的大小, 并输出比 较结果;
本申请所涉及的调整阈值主要是指终端需要进行放音响度调整的判断 条件, 其可以是一个确定的数值, 那么, 此时的比较结果则只有大于调整 阈值和小于调整阈值两种情况, 这种调整方式的效果较佳, 其可以保证放 音响度差值为一个固定的值, 而放音响度差值则与终端用户的使用感受直 接相关, 当放音响度差值保存不变时, 相当于终端用户听到的终端放音效 果稳定不变, 效果最佳, 但是, 在实际应用中, 终端所处环境会经常变化, 这种调整方式会导致终端需要实时调整放音响度的大小, 会造成电量的浪 费;
相应的, 在其他实施例中, 调整阈值还可以是两个及以上个数的数值 或一个取值范围, 此时的比较结果将有大于调整阈值的最大值、 小于调整 阈值的最小值及处于调整阈值的最大值与最小值之间三种情况, 这种实施 例可以具备一定的兼容性, 如当比较结果为处于调整阈值的最大值与最小 值之间时, 不对终端放音响度进行调整, 在一定程度上可以降低电量的浪 费;
S 104: 终端根据比较结果对放音响度进行调整。
当调整阈值的个数不同时, 具有不同的调整方案, 现分别给予说明: 当仅有一个调整阈值时, 根据比较结果对放音响度进行调整的步骤包 括: 当比较结果为放音响度差值大于调整阈值时, 提高放音响度, 当比较 结果为放音响度差值小于调整阈值时, P争低放音响度; 当有两个及以上调整阈值时, 根据比较结果对放音响度进行调整的步 骤包括: 当比较结果为放音响度差值大于调整阈值的最大值时, 提高放音 响度, 当比较结果为放音响度差值小于调整阈值最小值时, P争低放音响度, 当比较结果为放音响度差值处于调整阈值最小值与调整阈值最大值之间 时, 不调整放音响度。
可以预见的是, 在本申请的其他实施例中, 可以通过设置三个以上的 调整阈值或两个以上的调整阈值范围的方式, 来实现对放音响度调整值的 确定; 例如: 设置两个以上的调整阈值范围的方式时, 当比较结果为放音 响度差值处于 (1 , 2 )之间时, P争低 4分贝的放音响度值, 当比较结果为 放音响度差值处于 (2, 3 )之间时, P争低 2分贝的放音响度值, 当比较结 果为放音响度差值处于 (3 , 4 )之间时, 不调整, 当比较结果为放音响度 差值处于 (4, 5 )之间时, 增加 2分贝的放音响度值, 依此类推, 不再赘 述。
图 2 为本发明第二实施例提供的放音响度调整方法的示意图, 由图 2 可知, 在本实施例中, 放音响度调整方法包括以下步骤:
S201-S204: 终端获取环境声音信号及内部声音信号, 根据环境声音信 号及内部声音信号获取放音响度差值; 终端比较放音响度差值与至少一个 调整阈值的大小, 根据比较结果对放音响度进行调整; 这 4个步骤与图 1 相同, 不再赘述;
S205: 根据调整时的放音响度差值及修正阈值对调整阈值进行更新; 该步骤的目的是为了使得终端每次对放音响度进行的调整都是在前次 的调整基础之上进行的, 这样可以使得终端由一环境到另一环境移动时, 不会出现响度调整的断层; 具体的, 当调整阈值的个数不同时, 具有不同 的更新方案, 现分别给予说明:
当仅有一个调整阈值时, 根据调整时的放音响度差值及修正阈值对调 整阈值进行更新的步骤具体为: 将调整时的放音响度差值与修正阈值之和 / 之差作为新调整阈值, 或者将调整时的放音响度差值直接作为新的修正阈 值;
当有两个及以上调整阈值时, 根据调整时的放音响度差值及修正阈值 对调整阈值进行更新的步骤具体为: 将调整时的放音响度差值与修正阈值 之和作为新调整阈值的最大值, 将调整时的放音响度差值与修正阈值之差 作为新调整阈值的最小值;
S206: 显示调整后的放音响度值。
执行该步骤的目的是为了使终端用户能够了解到调整后的终端放音响 度值, 避免用户在下次使用时, 因为放音响度值过大 /过小造成用户使用感 受差的问题。
可以预见的是, 图 2所示实施例中的步骤 S205及 S206的先后顺序是 可以倒换的。
