需要说明的是，第一声音数据的类型可以与第二声音数据的类型相同，第一声音数据的类型也可以与第二声音数据的类型不同，比如，第一声音数据为音乐类声音数据，第二声音数据为视频类声音数据，此处不作限定。It should be noted that the type of the first sound data can be the same as the type of the second sound data, and the type of the first sound data can also be different from the type of the second sound data. For example, the first sound data is musical sound data, The second sound data is video sound data, which is not limited here.
102、按照预设规则将第一声音数据划分为第一声音片段和第二声音片段，并按照预设规则将第二声音数据划分为第三声音片段和第四声音片段，第一声音片段与第三声音片段对应，第二声音片段与第四声音片段对应；102.

本实施例中，在获取待播放的第一声音数据以及第二声音数据后，按照预设规则将第一声音数据划分为第一声音片段和第二声音片段，并按照预设规则将第二声音数据划分为第三声音片段和第四声音片段，第一声音片段与第三声音片段对应，第二声音片段与第四声音片段对应。In this embodiment, after acquiring the first sound data and the second sound data to be played, the first sound data is divided into the first sound segment and the second sound segment according to the preset rule, and the second sound segment is divided into the second sound segment according to the preset rule. The sound data is divided into a third sound segment and a fourth sound segment, the first sound segment corresponds to the third sound segment, and the second sound segment corresponds to the fourth sound segment.

另外，第一时间周期和第二时间周期为预设时间周期，为了不影响立体音，预设时间周期与一个左声道和右声道的整数倍对应，若立体音需要多声道支持，则预设时间周期与一个左声道或右声道的整数倍对应，此时需要将左声道和右声道进行分类，具体的一种分类可以参见下表：In addition, the first time period and the second time period are preset time periods. In order not to affect the stereo, the preset time period corresponds to an integer multiple of a left channel and a right channel. If the stereo requires multi-channel support, Then the preset time period corresponds to an integer multiple of a left channel or a right channel.

本实施例中，将时间周期划分为不同的时间段，在不同的时间段将相应的声音片段发送给相应的接收设备，使得不同的接收设备播放不同的声音，在时间周期足够小的情况下，人耳分辨不出声音有断层，从而采用类似时分复用的方法实现了同时对不同的声音数据进行播放。所以本发明能够同时进行不同的声音播放，且不会形成混音，提高了收听效果。In this embodiment, the time period is divided into different time periods, and the corresponding sound clips are sent to the corresponding receiving devices in different time periods, so that different receiving devices play different sounds. When the time period is small enough , the human ear can't distinguish the faults in the sound, so the method similar to time division multiplexing is used to realize the simultaneous playback of different sound data. Therefore, the present invention can play different sounds at the same time without forming sound mixing, thereby improving the listening effect.

The device processes the 96KHz sampling frequency corresponding to sound data 1 and the 48KHz sampling frequency corresponding to sound data 2 , adjust the 48KHz sampling frequency corresponding to the sound data 2 to 96KHz. Then the device divides sound data 1 and sound data 2 into multiple sound segments and rearranges the numbers, the sound segments of sound data 1 are 1.1, 1.2, 1.3...1.m, and the sound segments of sound data 2 are 2.1, 2.2, 2.3... 2.n. The device first divides the first time period into two sections.
