}

自己调试发现transient和continuous不能混用。音振协同的文档,振动又必须传文件路径…

在HarmonyOS中,音振协同的振动模式由振动效果配置决定。若仅振动一次,可能是未设置循环参数。可通过vibrator模块的effectId配置振动效果,支持设置count参数实现循环振动。例如,使用预置的振动效果或自定义振动时序,并通过startVibration方法触发。需检查代码中是否设置了循环次数或持续时间。

是的,可以配置循环振动。从你的JSON配置来看,问题在于continuous事件的Curve参数设置不当导致振动快速衰减。

在continuous事件中,Curve数组的时间点需要基于事件的相对时间(0到Duration之间),而不是绝对时间。你的配置中Time值40和54超出了Duration:54的范围,导致振动效果异常。

要实现循环振动,建议:

  1. 使用多个continuous事件按时间序列排列
  2. 调整Curve参数,确保时间点从0开始,到Duration结束
  3. 通过重复模式或循环事件来实现持续振动效果

检查文档中关于时间轴和曲线参数的详细说明,确保时间数值在有效范围内。
