HarmonyOS鸿蒙Next中audioHaptic (音振协同) 的使用

audioUri和hapticUri需更改为目标音频资源的Uri，代码操作将音频和震动配置文件从rawfile送进沙箱路劲，然后再执行音频registerSource()操作，

demo：

async function resourceFile(resourcePath: string) {
  let uint8Array: Uint8Array = getContext()
    .createModuleContext("library")
    .resourceManager
    .getRawFileContentSync(resourcePath);
  let fileName = resourcePath.substring(resourcePath.lastIndexOf('/') + 1);
  console.log("${tag} fileName:${fileName}");
  
  let filePath = getContext().createModuleContext("library").filesDir + '/' + fileName;
  if (fileIo.accessSync(filePath)) {
    fileIo.unlinkSync(filePath)
  }
  let file: fileIo.File = fileIo.openSync(filePath, fileIo.OpenMode.READ_WRITE | fileIo.OpenMode.CREATE);
  
  fileIo.writeSync(file.fd, uint8Array.buffer);
  
  fileIo.closeSync(file);
  console.log("${tag} filePath:${filePath}");
  return filePath;
}

audioHaptic 振动可能只会有一种振动效果，声音可以并发，一次振动两次音效，如果是创建两个AudioHapticPlayer，应该是可以达到的

当前audiohaptic是振动对齐到音频的，所以是一对一的关系

这边audiohaptic是不支持并行播放音频，这边可以使用soundPool并行播放两个音频，再使用Vibrator进行振动，这样便可实现你要的效果，

soundPool 并行播放请参考demo：

import audio from '@ohos.multimedia.audio';
import media from '@ohos.multimedia.media';
import fs from '@ohos.file.fs'
import { common } from '@kit.AbilityKit';
import fileIo from '@ohos.file.fs';

let soundPool: media.SoundPool;
let streamId: number = 0;
let soundId1: number = 0;
let soundId2: number = 0;

let context = getContext(this) as common.UIAbilityContext;
let resourceDir = context.resourceDir;

let audioRendererInfo: audio.AudioRendererInfo = {
  usage: audio.StreamUsage.STREAM_USAGE_MUSIC,
  rendererFlags: 1
}

let PlayParameters: media.PlayParameters = {
  loop: 3, // 循环4次
  rate: audio.AudioRendererRate.RENDER_RATE_NORMAL, // 正常倍速
  leftVolume: 0.5, // range = 0.0-1.0
  rightVolume: 0.5, // range = 0.0-1.0
  priority: 0, // 最低优先级
}

let uri: string = "";

async function create() {
  soundPool = await media.createSoundPool(2, audioRendererInfo);
  loadCallback();
  finishPlayCallback();
  setErrorCallback();
  
  let filePath = context.resourceDir + '/tap.mp3';
  let filePath1 = context.resourceDir + '/push.mp3';

  let file = await fileIo.open(filePath, fileIo.OpenMode.READ_ONLY);
  let file1 = await fileIo.open(filePath1, fileIo.OpenMode.READ_ONLY);

  uri = 'fd://' + (file.fd).toString()
  let uri1 = 'fd://' + (file1.fd).toString()

  soundId1 = await soundPool.load(uri);
  soundId2 = await soundPool.load(uri1);
}

async function loadCallback() {
  soundPool.on('loadComplete', (soundId_: number) => {
    console.info('loadComplete, soundId: ' + soundId_);
  })
}

async function finishPlayCallback() {
  soundPool.on('playFinished', () => {
    console.info("recive play finished message");
    // 可进行下次播放
  })
}

function setErrorCallback() {
  soundPool.on('error', (error) => {
    console.info('error happened,message is :' + error.message);
  })
}

async function PlaySoundPool(index:number) {
  streamId = await soundPool.play(index);
  soundPool.setLoop(streamId, 2); // 播放3次
  soundPool.setPriority(streamId, 1);
  soundPool.setVolume(streamId, 0.5, 0.5);
}

async function release() {
  soundPool.stop(streamId);
  // 卸载音频资源
  // await soundPool.unload(soundId);
  setOffCallback();
  await soundPool.release();
}

function setOffCallback() {
  soundPool.off('loadComplete');
  soundPool.off('playFinished');
  soundPool.off('error');
}

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';

  async aboutToAppear(): Promise<void> {
    create();
  }

  build() {
    RelativeContainer() {
      Button("播放").width('33%').height('5%').onClick(async () => {
        PlaySoundPool(soundId1)
        PlaySoundPool(soundId2)
        // setOffCallback()
        // release()
      })
    }
    .height('100%')
    .width('100%')
  }
}

在HarmonyOS鸿蒙Next中，audioHaptic（音振协同）功能通过结合音频和振动反馈，提升用户体验。开发者可以使用AudioHapticManager类来管理音振协同效果。首先，通过getAudioHapticManager()获取实例，然后使用playEffect()方法播放音振效果，传入音频文件和振动模式。振动模式可通过VibrationEffect类定义，支持自定义频率、强度和时长。通过stopEffect()可停止播放。此功能适用于游戏、通知等场景，增强交互沉浸感。
