## vibrator.vibrate<sup>(deprecated)</sup>

vibrate(effectId: EffectId, callback?: AsyncCallback&lt;void&gt;): void

Triggers vibration with the specified effect. This API uses an asynchronous callback to return the result.

This API is deprecated since API version 9. You are advised to use [vibrator.startVibration](#vibratorstartvibration9) instead.

**Required permissions**: ohos.permission.VIBRATE

**System capability**: SystemCapability.Sensors.MiscDevice

**Parameters**

| Name  | Type                     | Mandatory| Description                                                      |
| -------- | ------------------------- | ---- | ---------------------------------------------------------- |
| effectId | [EffectId](#effectid)     | Yes  | Preset vibration effect ID.                                        |
| callback | AsyncCallback&lt;void&gt; | No  | Callback used to return the result. If the vibration starts, **err** is **undefined**; otherwise, **err** is an error object.|

**Example**

```ts
vibrator.vibrate(vibrator.EffectId.EFFECT_CLOCK_TIMER, function (error) {
  if (error) {
    console.error(`Failed to vibrate. Code: ${error.code}, message: ${error.message}`);
  } else {
    console.info('Succeed in vibrating');
  }
})
```

## vibrator.stop<sup>(deprecated)</sup>

stop(stopMode: VibratorStopMode): Promise&lt;void&gt;

Stops vibration in the specified mode. This API uses a promise to return the result.

This API is deprecated since API version 9. You are advised to use [vibrator.stopVibration](#vibratorstopvibration9-1) instead.

**Required permissions**: ohos.permission.VIBRATE

**System capability**: SystemCapability.Sensors.MiscDevice

**Parameters**

| Name  | Type                                 | Mandatory| Description                    |
| -------- | ------------------------------------- | ---- | ------------------------ |
| stopMode | [VibratorStopMode](#vibratorstopmode) | Yes  | Mode to stop the vibration.|

**Return value**

| Type               | Description                                  |
| ------------------- | -------------------------------------- |
| Promise&lt;void&gt; | Promise that returns no value.|

**Example**

```ts
// Start vibration based on the specified effect ID.
vibrator.vibrate(vibrator.EffectId.EFFECT_CLOCK_TIMER, function (error) {
  if (error) {
    console.error(`Failed to vibrate. Code: ${error.code}, message: ${error.message}`);
  } else {
    console.info('Succeed in vibrating');
  }
})
// Stop vibration in VIBRATOR_STOP_MODE_PRESET mode.
vibrator.stop(vibrator.VibratorStopMode.VIBRATOR_STOP_MODE_PRESET).then(() => {
  console.info('Succeed in stopping');
}, (error) => {
  console.error(`Failed to stop. Code: ${error.code}, message: ${error.message}`);
});
```


## vibrator.stop<sup>(deprecated)</sup>

stop(stopMode: VibratorStopMode, callback?: AsyncCallback&lt;void&gt;): void

Stops vibration in the specified mode. This API uses an asynchronous callback to return the result.

This API is deprecated since API version 9. You are advised to use [vibrator.stopVibration](#vibratorstopvibration9) instead.

**Required permissions**: ohos.permission.VIBRATE

| -------- | ------------------------------------- | ---- | ------------------------------------------------------------ |
| stopMode | [VibratorStopMode](#vibratorstopmode) | Yes  | Mode to stop the vibration.                                    |
| callback | AsyncCallback&lt;void&gt;             | No  | Callback used to return the result. If the vibration stops, **err** is **undefined**; otherwise, **err** is an error object.|

**Example**

  } else {
    console.info('Succeed in vibrating');
  }
})
// Stop vibration in VIBRATOR_STOP_MODE_PRESET mode.
vibrator.stop(vibrator.VibratorStopMode.VIBRATOR_STOP_MODE_PRESET, function (error) {
  if (error) {
    console.error(`Failed to stop. Code: ${error.code}, message: ${error.message}`);
  } else {
