**System capability**: SystemCapability.Multimedia.AudioHaptic.Core

**Parameters**

| Name| Type  | Mandatory| Description                                             |
| ----- | ----- | ---- | ------------------------------------------------- |
| type   | string | Yes  | Event type. The value is fixed at **'audioInterrupt'**.|
| callback | Callback<[audio.InterruptEvent](js-apis-audio.md#interruptevent9)> | No  | Callback used to return the audio interruption event when the subscription is canceled.|

**Example**

```ts
import { audio } from '@kit.AudioKit';

// Cancel all subscriptions to the event.
audioHapticPlayerInstance.off('audioInterrupt');

// For the same event, if the callback parameter passed to the off API is the same as that passed to the on API, the off API cancels the subscription registered with the specified callback parameter.
let isPlaying: boolean; // An identifier specifying whether rendering is in progress.
let isDucked: boolean; // An identifier specifying whether the audio volume is reduced.
let audioInterruptCallback = (interruptEvent: audio.InterruptEvent) => {
  // When an audio interruption event occurs, the audioHapticPlayerInstance receives the interruptEvent callback and performs processing based on the content in the callback.
  // 1. (Optional) The audioHapticPlayerInstance reads the value of interruptEvent.forceType to see whether the system has forcibly performed the operation.
  // Note: In the default focus policy, INTERRUPT_HINT_RESUME maps to the force type INTERRUPT_SHARE, and others map to INTERRUPT_FORCE. Therefore, the value of forceType does not need to be checked.
  // 2. (Mandatory) The audioHapticPlayerInstance then reads the value of interruptEvent.hintType and performs corresponding processing.
  if (interruptEvent.forceType == audio.InterruptForceType.INTERRUPT_FORCE) {
    // The audio focus event has been forcibly executed by the system. The application needs to update its status and displayed content.
    switch (interruptEvent.hintType) {
      case audio.InterruptHint.INTERRUPT_HINT_PAUSE:
        // The audio stream has been paused and temporarily loses the focus. It will receive the interruptEvent corresponding to resume when it is able to regain the focus.
        console.info('Force paused. Update playing status and stop writing');
        isPlaying = false; // A simplified processing indicating several operations for switching the application to the paused state.
        break;
      case audio.InterruptHint.INTERRUPT_HINT_STOP:
        // The audio stream has been stopped and permanently loses the focus. The user must manually trigger the operation to resume rendering.
        console.info('Force stopped. Update playing status and stop writing');
        isPlaying = false; // A simplified processing indicating several operations for switching the application to the paused state.
        break;
      case audio.InterruptHint.INTERRUPT_HINT_DUCK:
        // The audio stream is rendered at a reduced volume.
        console.info('Force ducked. Update volume status');
        isDucked = true; // A simplified processing indicating several operations for updating the volume status.
        break;

        // The INTERRUPT_HINT_RESUME operation must be proactively executed by the application and cannot be forcibly executed by the system. Therefore, the INTERRUPT_HINT_RESUME event must map to INTERRUPT_SHARE.
