本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,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,并不用于限定本发明。
图 1 是发明实施例提供的 一种根据周围环境调节音量大小的方法 的流程示意图,为了便于说明,只示出了与本发明实施例相关的部分。
在步骤 S101 中,记录用户设置的一组以上的周边环境声音强度区间和音乐播放时音量分贝的对应关系 。
在本实施例中, 可以在音响上预先设置一组以上的周边环境声音强度区间和音乐播放时音量分贝的对应关系,如:设置环境声音为 30 分贝到 40 分贝之间,对应的音乐播放时的音量分贝为 40 分贝到 50 分贝,或是设置环境声音为 41 分贝到 50 分贝之间,对应的音乐播放时的音量分贝为 51 分贝到 60 分贝等。
在步骤 S102 中, 统计一定时间内周边环境的声音强度。
通过 声音分贝测试仪可以实现统计工作,统计一定时间内周边环境的声音分贝数,如:在茶楼的大厅中安装声音分贝测试仪,通过声音分贝测试仪统计 5 分钟该茶楼环境的声音分贝数。
在步骤 S103 中, 计算所述一定时间内周边环境声音强度的平均值。
将上述统计一定时间内周边环境的声音分贝数进行求平均值,算出该环境在这段时间内周边环境的平均声音强度,如:根据上述记录 5 分钟茶楼的环境内的声音强度,算出该茶楼在这 5 分钟内的平均声音强度。
在步骤 S104 中, 根据所述平均值所处的所述周边环境声音强度区间,以所述强度期间对应的音量分贝播放音乐。
将上述计算得出的一定时间内的环境声音强度的平均值和预先设置好的环境声音强度区间进行对比,从而以所述强度期间对应的音量分贝播放音乐,如:通过计算得出环境声音强度为 42 分贝,根据我们预先设置好的环境声音强度为 41 到 50 分贝,所以对应播放音乐时的分贝为 51 到 60 分贝。
该 发明通过用户预设周边环境声音强度区间和音乐播放时音量分贝的对应关系,计算一定时间内周边环境声音强度的平均值,从而能根据当前环境的声音强度,调整音响输出的音乐音量。
图 2 是本发明实施例提供的一种 音响 的结构示意图,该 音响 包括 :
记录单元 21 ,用于记录用户设置的一组以上的周边环境声音强度区间和音乐播放时音量分贝的对应关系;
统计单元 22 ,用于统计一定时间内周边环境的声音强度;
计算单元 23 ,其输入端与所述统计单元 22 的输出端连接,用于计算所述一定时间内周边环境声音强度的平均值;
执行单元 24 ,其输入端分别与所述记录单元 21 的输出端以及所述计算单元 23 的输出端连接,用于根据所述平均值所处的所述周边环境声音强度区间,以所述强度期间对应的音量分贝播放音乐。
其工作原理是:记录单元 21 记录用户设置的一组以上的周边环境声音强度区间和音乐播放时音量分贝的对应关系 ; 统计单元 22 ,统计一定时间内周边环境的声音强度;计算单元 23 ,计算所述一定时间内周边环境声音强度的平均值;执行单元 24 根据所述平均值所处的所述周边环境声音强度区间,以所述强度期间对应的音量分贝播放音乐。
该 发明通过用户预设周边环境声音强度区间和音乐播放时音量分贝的对应关系,计算一定时间内周边环境声音强度的平均值,从而能根据当前环境的声音强度,调整音响输出的音乐音量。
